Title: Tracking servo circuit
Inventor: OINUMA AKIRA
IPC: G05D3/12
Filed: 1980-09-04
Abstract: PURPOSE:To previously prevent the out-of-tracking phenomenon, by foreseeing the disturbance of error signal of a tracking servo circuit caused by a defect produced during the production of a disk or the damage caused during the handling of the disk and then stopping the following of the servo system for a short time. CONSTITUTION:The laser beams reflected by a disk 1 are amplified by a preamplifier 8. One of these beams is changed into a video signal after the demodulation 9, and the other beam receives a tracking error detection 10 to be compared with the reference voltage given from a reference voltage generator 11 through a differential amplifier 12. Then a tracking mirror 5 is made movable via a drive amplifier 13. In this case, if a reduction of amplitude is caused to the output signal of the amplifier 8 due to a dropout, the pulse signal of a certain width is produced from a monostable multivibrator 16 by the trigger signal of an envelope wave detector 15 that constitutes a preholding circuit 14. Thus an analog gate 17 is turned off. Then the error signal is preheld by a holding capacitor 18 to eliminate the noise.

Title: Inter-frame coder
Inventor: YOSHIDA OSAMU
IPC: H04N19/65
Filed: 1992-05-15
Abstract: PURPOSE:To prevent the generation of sharp variation in picture quality by suppressing the sudden variation of information volume in a transmission buffer due to the increment of information volume in a refresh period. CONSTITUTION:An intra-frame processing/inter-frame processing switching judging circuit 113 compares a forecasting signal obtained from a movement compensating circuit 111 with a current signal and applies '0' (for intra-frame processing) or a forecasting signal (for inter-frame processing) to a subtractor 104 so that the intra-frame processing is executed when a deviation is large or the inter-frame processing is executed when the deviation is small. The circuit 113 is controlled at its switching so that the intra-frame processing is forcedly executed in accordance with a signal applied to its terminal C, and since the signal is a movement detection signal applied from a movement detecting circuit 102 for detecting the image movement of a current signal, an intra-frame processing period is shortened when movement is large and the period is extended when the movement is small to average the information volume of an output buffer.

Title: Transmitter-receiver for teletext
Inventor: ANDO MORIO
IPC: H04N7/025
Filed: 1987-05-22
Abstract: PURPOSE:To reduce the burden of a main control part by decoding respective code data which is received, retrieving external character code data which is stored in an external character memory, reading pattern data and disconnecting a bus buffer while retrieval processing. CONSTITUTION:A central processing means CPU13 decoding respective code data which are received and an external character memory control means 20 which accesses the external character memory 19 independent of the CPU13 are provided. While the external character memory 19 is being accessed, bus paths 14 and 22 between the external character memory 19 and the CPU13 are disconnected. Since the external character memory control means 20 retrieves the external character memory 19 while the CPU13 executes an instructed processing, it comes to be unnecessary for the CPU13 to retrieve the external character memory 19, and the CPU13 can execute other processings as much. Thus, the processing burden of the CPU can be reduced.

Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To eliminate a foreign matter in an opening/closing path by increasing driving force at the time of repeating opening/closing action when load acts upon the opening/closing action of a car door. SOLUTION: When abnormal load is reported from an abnormal load detector during the movement of a car door in an opening/closing direction, the car door moves in the opening direction. The car door is once fully opened and then moved again in the closing direction. At this time, torque of a door opening/closing motor 32 is increased by the action of variable resistance 35. When abnormal load is reported again during the movement of the car door in the closing direction, the car door moves again in the opening direction. The car door is once fully opened again and then moved again in the closing direction. At this time, torque of the door opening/closing motor 32 is further increased by the action of variable resistance 35, 36. Unless abnormal load is detected during the movement of the car door in the closing direction, the opening/closing action of the car door is completed.  If abnormal load is reported, an elevator device is stopped and put out of restart.

Abstract: PURPOSE: To improve lubricating efficiency and to prevent wear and seizure by forming a plurality of projecting portions on the inside surface side of the bottom wall of a bearing outer ring and effectively introducing the grease on the wall in between the contact surfaces.  
     CONSTITUTION: The flat portion of the inside surface of a bottom wall 41 is formed with a plurality of projecting portions 46 each having a top portion in the shape of a curved surface or mount and an arbitrary plan shape, the top portion in sliding contact with a mating part during use.
