วันนี้ผมขอแนะนำ Application ที่ใช้ AC Servo Motor อีกตัวครับครับ AC Servo Motor เป็นอุปกรณ์ที่นิยมใข้ในการขับเคลื่อนมากมาย อย่างแพร่หลาย ด้วยคุณสมบัติที่สามารถควบคุมตำแหน่งของ ตัวเองได้อย่างแม่นยำ แตเจ้า AC Servo Motor เอง ยังมีอีก 1 Mode ก็คือ Torque Mode ซึ่งสามารถที่จะควบคุมแรงบิตของตัวเองได้ ดังนั้น ได้มีหลาย ๆ บริษัทพัฒนาผลิตภัณฑ์ ของตัวเองขึ้นมาก เป็ลลักษระของการ ควบคุม แรงบิต เช่น Servo Press (ควบคุมแรงกด ด้วย Servo Motor) และอีกหนึ่งตัวที่นิยมนำมาใช้งานในการขัน สกรู หรือ โบล ก็คือ AC Servo Nut Runner
AC Servo Nut Runner เป็นอุปกรณ์ที่นิยมนำมาขัน Bolt หรือ Screw หรือ Nut เพื่อควบคุมแรงในการขัน ให้สามารถที่จะรับประกันคุณภาพได้ว่า ไม่มีการขัน แน่นในทุก ๆ ครั้งของการขัน ด้วยค่าที่ เท่า ๆ กัน และได้พัฒนาให้สามารถ บันทึกค่าต่าง ๆ ได้ เพื่อ รองรับการตรวจสอบกลับ ถึงคุณภาพ สร้างความมั่นใจให้กับระบบการผลิต และลูกค้า
นอกจากนี้ ทางบริษัทผู้ผลิต AC Servo Nut Runner ยังได้ ศึกษาเกี่ยวกับพฤติกรรม ของแนวแรง การคลายตัว ปัญหา การขันที่ผลิดรูปแบบ ปีนเกลียว ขันไม่สุด ขันแล้วคลาย อะไรต่าง ๆ อีกมากมายซึ่งผู้ผลิต ก็ได้ออกแบบให้สามารถที่จะตรวจจับได้ มี Step ในการขัน ที่หลาย ขั้นตอนขึ้นไม่เหมือน กับการใช้คนขัน และมีการ ควบคุมการขัน หลาย ๆ ตัวพร้อมกัน ให้มีความสัมพันธ์กันได้ อีกตัวทีสำคัญคือ Angle เป็นลักษระของการควบคุม องศาของการขัน หลังจากที่ การขันได้ ค่า Torque ที่ต้องการแล้ว ต้องขั้น เลยไปอีกกี่องศา ซึ่งสามารถที่จะกำหนดได้ เหมือนกับการขันของคนที่บอกว่า ขันพอตึงมือ (แล้วตึงมือยังไงจารย์ ^_^")

finding it amusing.
The hilarious video shows six-month-old Stevie, who is
from St John's in Newfoundland, Canada, with her arms up high in a glass tube, known as
a Pigg-O-Stat, with her mother laughing in the background.
The infant suffers from Down's Syndrome as well as a congenital
heart defect.
The device, which according to manufactures has been around
since the 1960s, aims to hold babies or small
children still during X-rays.
The Pigg-O-Stat is an all-in-one pediatric immobilization device
designed for positioning infants and young children for an appropriate
x-ray without significant complications.

The manufacturer describes the Pigg-O Stat as an 'all-in -one paediatric immobilisation device designed
for positioning infants and young children for an appropriate x-ray without significant
complications.'
They go onto say that the device safely secures the child
and allows the x-ray technician to be brief and efficient while the
child remains immobilised.
The manufacturer adds: 'the Pigg-O Stat provides x-ray technicians the best
opportunity to capture a great picture on the first attempt.
With fewer retakes required, infants receive significantly less exposure
to radiation.'

People in Switzerland have voted for strict controls on executive
pay
68 per cent backed plans to veto pay-outs to bosses
Move sparked by anger over the big bonuses blamed for fuelling
risky investments
It comes after the EU announced plan to cap bankers' bonuses at a year's pay

Swiss citizens have voted to impose some of the world's strictest controls
on executive pay.
Early returns in a referendum revealed 68 per cent backed plans for shareholders to veto executive pay and for a ban on big rewards for new and departing managers.
The clear majority came as a surprise given fierce opposition and intense campaigning by business lobby group Economiesuisse, which warned the proposals will damage the country's competitiveness
and scare away international talent.
Support for the move was sparked by anger over the big bonuses blamed for fuelling
risky investments that nearly felled Swiss bank UBS, as well as
outrage over a proposed $78 million payment to outgoing
Novartis chairman Daniel Vasella.
Claude Longchamp, of pollsters Gfs.Bern,
said the public outcry last month that forced Novartis to cancel Vasella's 'golden goodbye' helped drive the campaign.
The Swiss vote for stricter rules on execuitve
pay was sparked by outrage over a proposed $78 million payment to outgoing chairman of drugs
company Novartis Daniel Vasella (pictured)
'It emotionalised and it mobilised,' he said.
Thomas Minder, the businessman-turned-politician behind the campaign, says his proposals are aimed at ending a culture of short-termism and rewards for managers of badly-run companies rather than just capping salaries.

Despite threats from some executives, Switzerland is unlikely to see an exodus of big companies who have
previously been drawn to the country by low taxes, stable politics and business-friendly laws.
And companies will seek ways around the new
rules to reward executives, just as banks in Europe
are looking to soften the impact of a cap on bonuses for top staff agreed by European politicians on Thursday.
The Swiss vote comes as the European Union tries to push through a proposal
which will mean bankers bonuses will be capped at a year's pay and a perk of two years' salary could only be paid if a majority of shareholders agreed to it.
Downing Street said Prime Minister David Cameron had ‘real concerns' about the plans
and warned it must not be allowed to stifle Britain's role as a global banking centre.

The deal must be signed off by EU governments before coming
into force next year but Chancellor George Osborne
is expected to argue against it at a meeting of European finance ministers
next year.
Boris Johnson joined the chorus of British opposition, branding the plans 'deluded' and 'self-defeating'.
The London Mayor warned it would simply play into the hands of the City of London's overseas.
Mr Osborne is expected to try to block the plans, claiming it would prevent City firms hiring the best staff, prompting an exodus of top talent to New
York.
The deal must still be signed-off by EU governments before coming into force in 2014 but the UK is struggling to convince other countries it is a bad idea.
If Britain loses its showdown with Brussels, it would
mean the most draconian clampdown on fat cats' perks since the financial crisis of 2008.
Swiss companies accounted for five of the top 10 best-paid chairmen in Europe in 2011,
but only the heads of Novartis and Roche made it into the continent's top 10 for chief executives.
While anger at multi-million dollar payouts for executives has spread
around the globe since the financial crisis, the Swiss system of direct democracy means populist proposals have a greater chance of implementation.
Swiss citizens get to vote on a range of topics in up to
four national referendums each year.
A few other countries, including the United States and Germany, have introduced
advisory 'say on pay' votes in response to anger over inequality and corporate excess.
Britain is also planning to give shareholders a binding vote on pay and 'exit
payments' at least every three years.
The near collapse of flagship bank UBS in 2008 stoked anger among
Swiss who blamed its heavy losses on rewarding bankers to
make risky bets
Thomas Minder's initiative in Switzerland forces binding votes on compensation every year as
well as on board composition and would also ban bonus
payments to managers if their companies are taken over.
The plan also includes possible jail sentences and fines for breaching the new rules.
While Switzerland has fared relatively well through the
financial crisis, the near collapse of flagship bank UBS in 2008 stoked anger among
Swiss who blamed its heavy losses on rewarding bankers to make risky bets.
Last year, more than one third of UBS shareholders rejected the bank's plans for executive pay - including
a 4 million franc signing-on fee for new German chairman Axel Weber - after a sub-par 2011 profit and a $2 billion rogue trading scandal.
The centre-left Social Democrats are already pushing for another referendum on even tougher curbs on executive pay - they want to limit
the annual compensation of top managers to just 12 times that of
their lowest-paid worker.
