Title: Take-out device for workpiece in container
Inventor: MIKAMI AKIRA
IPC: B65G47/90
Filed: 1986-04-18
Abstract: PURPOSE:To speed up the take-out operation of several kinds of workpiece in a container, by providing a container coating table an a workpiece retainer device in a workpiece take-out device for taking out workpiece in the container during a ferrite magnet being calcined, and also by providing a reversing device for the container with respect to the workpiece take-out device. CONSTITUTION:A container 25 set on a table 21 is located and clamped by actuating a cylinder 27. Then, motors 53, 54 are driven to slack a belt 18 by a predetermined length. A cylinder 9 is operated to move a retainer device 15 toward the container 25. Further, a workpiece is retained in association with the operation of the cylinders 19, 20 while the operation of a rotary actuator 2 reverses the container 25, and therefore, the workpiece is taken out onto a pay-out surface in association with the operation of the cylinder 19. Again the cylinders 19, 20 are operated to shift the workpiece onto another conveyer or the like, and the belt 18 is rewound by the motors 53, 54. Again the container is reversed by the rotary actuator 2, and the container 25 having been emptied is taken out.

Filed: 1981-06-12
Abstract: PURPOSE:To get rid of influence due to vibration of a focal control driving device, by using a storage-type photoelectric converting element, in case of measurment of thickness by automatic focal control which has used a pattern projected on the surface and the reverse side to be measured. CONSTITUTION:Patterns 2, 2' are projected on bodh water surfaces by opposed objective lenses 4, 4' on the surface and the reverse side of a silicon wafer 9, respectively, these projected patterns are also image-formed on image pickup devices 8, 8' by objective lenses, and they are focused by lens driving mechanisms 5, 5' so that contrast of these images becomes maximum. Thickness of  the wafer is detected from a position of the lenses which have been focused.  When the lens is finely moved by a driving motor, a position Z shows vibration  of a period TS, therefore, when a storage-type photodiode two-dimensional array sensor is used and its scanning period is made to coincide with the vibration  period TS, the quantity of incident light of the period t1-t2 of a picture signal  6B is integrated by a scanning start signal 6A, therefore, a variation of the  quantity of light by vibration is averaged.

Title: Oscillation circuit
Inventor: TANAKA YASUSHI
IPC: H03B5/32
Filed: 1994-04-28
Abstract: PURPOSE:To reduce the negative feedback noises which are generated from the gate elements, etc., that are connected to an oscillator when the oscillation is started and to secure the stable and satisfactory oscillation start characteristic of the oscillator. CONSTITUTION:The gate elements 10-12 are connected to an oscillator 100 which consists of a NAND gate 1, a crystal oscillator 2, etc. Then the oscillation pulses are outputted in response to the oscillation output of the oscillator 100 by the actuation of elements 10-12. The oscillator 100 starts its oscillating operation by the positive feedback function of an output signal defined to an input signal. A prescribed difference is set between the oscillating operation point voltage of the oscillator 100 and the input threshold voltage of the element 10. Thus the switching actions of elements 10-12 are suppressed when the oscillator 100 starts its oscillating operation. Therefore the negative feedback noises caused by the switching actions of elements 10-12 are reduced and the stable oscillation start characteristic is secured for the oscillator 100 with no disturbance given to the positive feedback function.

Abstract: PURPOSE:To make it possible to use light sources having the same wavelength and the same photodetectors by making frequencies of light emitting element driving subcarriers different from one another in an optical transmission system. CONSTITUTION:In case of the transmission from a terminal 1 to a terminal 1', the subcarrier from a subcarrier generator 8 is modulated to drive a light emitting element 3, and an optical signal is made incident to an optical fiber 5 through an optical coupler 6. The optical signal from the optical fiber 5 is branched in an optical coupler 7, and the electric signal from a photodetector 4' is allowed to pass through a band-pass filter, and a modulated subcarrier is outputted to the terminal 1'.
