Title: Lock device
Inventor: SASAKI KAZUO
IPC: E05B49/00
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To increase a distance in which communication with a transponder is possible without increasing consumption power of a leader. SOLUTION: A lock cylinder 10 is supported and fixed on an attaching panel face P while the idling ring 21 holds a coil 2c wound around the periphery of a lock cylinder 20. In this case, a part thereof is cut to fill an insulator 21a such as a curing resin and formed so as not to become an annular conductive body. Thereby as the result where the occurrence of an induction magnetic field ϕ' canceling a magnetic flux ϕ which a coil 2c generates is suppressed, a distance for communication with a transponder 1 can be increased without increasing consumption power of a leader.

Abstract: PURPOSE:To eliminate the number of components and to improve the reliability and noise resistance, by leading an output of a photo detector required for the carrying control of a medium into a scanning area, in a device scanning the information of the paper medium to apply photoelectric conversion, so as to eliminate the need for a carriage control circuit. CONSTITUTION:A light from a lamp 6 lighting a paper 3 is guided through optical fibers 7A-7C to light transmission ends 4a-4c of a paper detecting section, and the light received on receiving ends 4a'-4c' provided oppositely is led in an image forming objective area of a photoelectric converting element 1. When the paer sheet 3 is carried and reaches a position interrupting the photo detecting ends 4a', 4b', only the photo detecting end 4c' in the image forming objective area of the photoelectric converting element 1 is brightened and an output is obtained. The discrimination is performed at each photo detecting section with a strobe pulse generated corresponding to the element number of the photoelectric converting element in advance. Thus, the circuit for carriage control is not required.

Title: Cooling device
Inventor: KOJIMA TAKAO
IPC: F28D7/10
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To carry out heat exchange effectively even if a capillary tube has a length longer than that of a suction pipe by disposing the capillary tube formed in a coil-like shape in an interior of the suction pipe. SOLUTION: A capillary tube 7 passed through a suction pipe 11 is formed in a coil-like shape and has a length capable of corresponding to characteristic conditions of a refrigerant used or temperature conditions of a refrigeration cycle. Then, effective heat exchange becomes possible because the capillary tube 7 carries out direct thermal conduction with the refrigerant within the suction pipe 11. Furthermore, the capillary tube 7 can be set at a length corresponding to the characteristic conditions of the refrigerant used or the temperature conditions of the refrigeration cycle by forming the capillary tube 7 in a coil-like 7a shape and omission of operation of soldering the tube 7 and the suction pipe 11 can be contrived. Because the capillary tube 7 is fixed within the suction pipe 11, its vibration can be controlled.

Title: Automatic gain control system
Inventor: TOKIMASA SATORU
IPC: H04B3/10
Filed: 1979-11-28
Abstract: PURPOSE:To enable automatic gain control without giving interference to PCM- FDM signal, by picking up the pilot signal in PCM-FDM signal and suppressing the transmission level variance with this signal. CONSTITUTION:When a pilot signal in PCM-FDM signal is varied during transmission, the pilot signal picked up with a pilot filter 13 is rectified at a rectifying circuit 14, and a DC component is varied through an LPF15. This variable DC component controls the gain of an automatic control amplifier 11 and the variance of transmission level is suppressed. Thus, when PCM-FDM signal is located to the bands of a plurality of basic supergroups and transmitted, automatic gain control can be made without giving interference to PCM-FDM signal to make easy the long distance transmission.

Title: Video camera containing automatic focus detecting circuit
Inventor: AMIKURA TAKASHI
IPC: G02B7/28
Filed: 1984-07-26
Abstract: PURPOSE:To avoid the evil effects given to an effective reproduction screen although a power supply voltage level has a drop in a start mode, by securing a coincidence of a start timing of an automatic focus detecting circuit within a vertical flyback time of the video signal reproduced by a video camera. CONSTITUTION:An end of a start switch SW1 is connected to a power supply VCC with the other end connected to an input terminal D of an FF20. A vertical synchronizing signal VD is supplied to an input terminal CK of the FF20 and an output terminal Q gives the ON/OFF control to a transistor TR21. When the SW1 is turned on and the signal VD is supplied, the output Q of the FF20 delivers the actual start timing of an automatic focus detecting circuit. The TR21 is turned on when the output Q is set at a high level, and a current (i) flowed by the power supply voltage V has the timing to produce a large fluctuation (a) at an exact time point of the vertical synchronizing signal, i.e., within a vertical flyback time. Then the large fluctuation (a) is changed into a small fluctuation (b) by a synchronizing signal SYNC given from a microcomputer 11.

Title: Linear motor type curtain opening/closing device
Inventor: KAWAKITA MASAHIKO
IPC: H02P25/06
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a linear motor type curtain opening/closing device capable of raising the thrust of a motor when a curtain is stopped by the repulsion of the curtain or an obstacle or the like in the middle of opening/closing. SOLUTION: Only one of a pair of left and right mover units 4a and 4b stopped in the middle of opening/closing is energized. In this case, the thrust of a linear motor is raised by applying a double voltage to one of the mover units and the inconvenience that opening/closing can not be performed or opening can not be completely performed since an obstacle is present or the thrust lacks due to the repulsion of curtains 5a and 5b drawn to an opening direction end part and turned to a folded state in the middle of opening 7 closing is evaded. Also, when timer time set at prescribed time elapses, since an energizing processing to only one of the pair of the left and right mover units 4a and 4b is automatically stopped, the situation that energizing time to the mover units 4a and 4b becomes long, a coil generates heat and the charge amount of a battery lacks is prevented.
