Title: Wafer transfer device
Inventor: OSHIMA YASUTAKE
IPC: H01L21/68
Filed: 1991-09-20
Abstract: PURPOSE:To move the plurality of wafers at the same time from a wafer carrier to a wafer boat where wafers are placed at small pitches. CONSTITUTION:Between supporting plates 32, 33 which are installed on a moving hand 3, spacers 50 which can be inserted between the plurality of wafers W on a wafer boat are located. When an air cylinder 40 does not work, the spacers 50 are separated from each other by a compression spring and a parallel pitch is large. When the air cylinder 40 works, the spacers 50 are brought very close together and the arrangement pitches become small. The plurality of wafers W on the wafer boat are all held simultaneously by a wafer supporting plate 64 and are moved to a wafer carrier. By this method, the plurality of wafers can be moved at the same time from the wafer carrier to the wafer boat where wafer are arranged at small pitches.

Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a safety device for a telescope capable of preventing an object emitting a strong light beam such as the sun from coming into a visual field and damaging an observer's eye. SOLUTION: The light made incident through a pin hole 6 and a field diaphragm 7 having the field larger than the real field of the telescope by a specified angle, which are arranged on an axis 5 parallel with the optical axis 4 of the telescope, is measured by a photoelectric element 8.

Abstract: PURPOSE:To secure a requisite and proper displacement as well as to make stable injection quantity control performable by performing the on-off operation of a valve system through a shaft rod solidly connected to an almost U-shaped metal member supporting and fixing a piezoelectric element. CONSTITUTION:A piezoelectric element 10 is inserted into, and fixed to a groove 9b of a U-shaped metal member 9.

Title: Synchronization separating circuit
Inventor: MITANI HIROSHI
IPC: H04N5/08
Filed: 1986-10-13
Abstract: PURPOSE:To prevent the occurence of pulse-like noise and to easily make a titled circuit into an intergrated circuit even if a composite video signal with which pulse-like noise is overlapped is added by providing plural comparators, delay units, an output breaker and a reference voltage generator. CONSTITUTION:If the composite video signal (a) with which pulse-like noise is overlapped is added to a synchronous separating circuit, a signal (b) in which a pulse generated by a synchronizing signal and pulse-like noise is included appears in an output from a comparator 101. A delay unit 104 delays the signal (b) and a signal (c) can be obtained. Pulse-like noise is taken out in the output from a comparator 105, and the output is delayed by a delay unit 106, whereby a signal (e) can be obtained. In an output breaker 107, the output becomes L only when the signals (c) and (e) become H, whereby pulse-like noise does not appear in the output signal (f). Since delay time in the delay units 104 and 106 is considerably short, the capacity of a capacitor for executing delaying can be minimized and it can be formed in the integrated circuit. Thus, the occurence of pulse-like noise can be prevented and the titled circuit can be easily made into the integrated circuit even if the signal (a) is inputted.
