Title: Centering equipment for parts
Inventor: AKAHORI MASAHIRO
IPC: H05K13/04
Filed: 1989-07-29
Abstract: PURPOSE:To realize the accurate positioning at a desired center, by a method wherein, when a front pinching claw and a rear pinching claw pinch a parts and then a right pinching claw and a left pinching claw approach with each other, the right and the left claws are inserted wedge-wise between the front and the rear claws to open them in the front-and-rear direction. CONSTITUTION:When a parts is subjected to centering at a desired center on a substrate 34, a centering apparatus 1 is moved by a robot. Thereby the center between front and rear pinching claws 15, 16 and the center between right and left pinching claws 21, 22 are made to coinside with a center position 36. The pinching claws 15, 16 are made to approach with each other, and the parts 36 is pinched between the pinching claws 15 and 16. Next the pinching claws 21, 22 are made to approach, and inserted wedge-wise between the claws 15 and 16 to open them in the front-and-rear direction. Hence the pinching of the parts from front and rear is released. Thereby the parts 35 is accurately subjected to centering at the desired position, without generating pivotary movement.

Filed: 1989-08-01
Abstract: PURPOSE:To stabilize wavelength of a narrow-band laser beam with relatively compact and inexpensive configuration by using non-narrow laser beam as a reference light for a narrow-band laser beam. CONSTITUTION:First of all, a non-arrow laser beam Q2 incides a fabry-perot interference meter 34 and light intensity peak position of interference pattern due to this laser beam Q2 is detected and is stored into a memory part 42. Then, a laser switcher 31 is switched, thus enabling one part Q1' of a narrow- band laser light Q to incide the fabry-perot interference meter 34 and light intensity peak position of interference pattern due to this laser beam Q1' to be detected. Angle adjustment of a grating 22 is repeated until both light intensity peak positions agree each other. Then, if they agree, light intensity peak position detection operation of interference pattern due to the laser beam Q2 which is not narrow-banded is performed again and the similar operation is repeated. Thus, the central wavelength of the laser beam Q1 which is narrow- banded constantly agrees with that of the laser light Q2 which is not narrow- banded.
