Title: Semiconductor device
Inventor: KATOU TATSUMASA
IPC: H01L21/02
Filed: 1983-09-16
Abstract: PURPOSE:To prevent generation of a slip line and reduce the warp of a substrate by making the circumferential end of the semiconductor substrate a round or tapered surface. CONSTITUTION:The circumferential end of a substrate is made a slowly tapered surface 3 or a round surface 4. This reduces change of black body radiation from the circumferential end of the substrate during a high temperature short time heat treatment, uniformly distributes temperature in all the semiconductor substrate and extremely reduces the slope of temperature at the circumference. Consequently, during an isothermal high temperature short time heat treatment by a halogen lamp or a graphite heater, a slip line is prevented and the warp of the substrate is reduced whereby manufacture of a high quality and highly integrated LSI is made possible.

Title: Control circuit including operation stabilizing circuit for automatic focusing camera
Inventor: ENOMOTO SHIGEO
IPC: G02B27/64
Filed: 1979-12-28
Abstract: PURPOSE: To suppress the occurrence of unstable operation by providing an operation stabilizing circuit which generates the signal for forcibly stopping a photographic lens near the focusing position.  
     CONSTITUTION: The signal outputted from a detector 3 is logically processed by a direction instructing circuit 4 and a stop instructing circuit 5. The outputs of both instruction circuits 4, 5 are inputted to a focusing motor driving circuit 6 via an AND circuit. The operation stabilizing circuit 2 within the dotted line frame is provided. If the output signal of the Q' output terminal of the direction instructing circuit 4 inverts, a positive pulse is applied to the 1st binary counter 7 by a CR circuit, and the output terminals 1W8 of the counter 7 are reset; at the same time, said counter receives the clock from an oscillator 8 and counts the same. When the Q' output from the circuit 4 inverts while the 1st counter 7 is counting, the 2nd counter 10 is reset and starts counting the clock from the oscillator 8. If the 3rd and 4th inversions occur, the 1st, 2nd counters 7, 10 are reset every time, hence, the focusing motor remains stopped.

Inventor: YOSHIDA RITSUO
IPC: H04N5/92
Filed: 1988-07-11
Abstract: PURPOSE:To certainly discriminate the recording mode of reproduced FM luminance signals irrespective of the content of video signals and to reproduce the luminance signals stably by discriminating the recording mode of the luminance signals during the nonpictorial signal period of the luminance signals. CONSTITUTION:A PG head 6 generates a control signal II by giving signals generated by the rotation of a head drum to a monostable multivibrator (MM) 7. The signal II becomes 'H' only immediately after a switch circuit 5 is switched and turns on a switch circuit 10. Therefore, signals of a nonpictorial signal period immediately after rotary heads 1 and 2 respectively start to trace tracks A and B are led to BPFs 11 and 12 and signals of a stable level having no relation with the content of video signals are outputted from the BPFs 11 and 12. The signals outputted from the BPFs 11 and 12 are FM-detected at DETs 13 and 14 and the detecting outputs of the DETs 13 and 14 are given to a comparator 17 through LPFs 15 and 16. Thus the recording mode is certainly discriminated and stable reproduction of luminance signals can be performed.

Abstract: PURPOSE:To form a complicated waterspout shape with a small number of nozzles by connecting a nozzle with the downstream side of a control valve inserted in a water supply pipe through a flexible pipe joint and inserting through this upper part into an opening of a crossing part of a stereo-cross- shaped elevation-variable mechanism. CONSTITUTION:When a plurality of servo-driven motors 4 and 4 are rotated respectively in X and Y directions, a plurality of curved belt sheets in an elevation-variable mechanism are rotated respectively in alpha and beta directions. As the result, the base part of an elevation-variable nozzle 12 is rotated along a nozzle supporting stage 10. In this time, as the intermediate part of the elevation-variable nozzle 12 is loosely restricted in a long hole 8 of each curved belt sheet, the ceutral line of the elevation-variable nozzle 12 points to a specified elevation. By the way, variation of the elevation can be done by either successive rotation or simultaneous rotation of the servo-driven motors 4 and 4 and for the simultaneous rotation, the cross space of the elevation-variable mechanism 5 may be rotatively moved in the direction r. In addition, rotation of each servo-driven motor 4 and 4 is controlled by means of a computor.

Filed: 1989-07-05
Abstract: PURPOSE:To eliminate the necessity performing the disassembling investigation or cyclical disassembling investigation of rotary electrical machinery by automatically detecting the abnormality of a rotor conductor to output an abnormality detection signal. CONSTITUTION:The shaft voltage of an induced electromotor 1 is detected to be expand ed in Fourier series and the secondary harmonic component alpha2, tertiary harmonic component alpha3 and quadratic harmonic component alpha4 thereof are respectively compared with the upper limit value alpha4 of the secondary harmonic component and, when either one of the components is larger than the upper limit value, an abnormality detection signal Sa is outputted from an abnormality detection apparatus 11 and the abnormality such as cutting of a rotor conductor is automatically detected. In this case, unlike a conventional method, it is unnecessary to disassemble the induced electromotor 1 for the sake of investigation or cyclical disassembling investigation also becomes unnecessary. Since a power supply switch 2 is subjected to trip operation on the basis of the output of the abnormality detection signal Sa so as to cut off the supply of power to the induced electromotor 1, a stator is surely prevented from sustaining damage.
