Title: Composition of adhesive for flexible printed circuit board
Inventor: INMAKI NORIKO
IPC: H05K3/38
Filed: 1995-04-25
Abstract: PURPOSE: To prevent the adhesion from lowering after immersion into solder by employing a thermosetting resin, acrylonitrile butadiene rubber and a specified antioxidant as essential components. CONSTITUTION: A thermosetting resin, acrylonitrile butadiene rubber and a specified antioxidant, i.e., a thioether based compound shown by a formula, are essential components. In the formula, R represents a 12-14C alkyl group. An adhesive composition is admixed with 0.01-5.0wt.% of antioxidant. Since a specified antioxidant is admixed, the acrylonitrile butadiene rubber is protected against thermal deterioration due to the catalytic action of copper during solder immersion. Consequently, lowering of adhesion can be suppressed after solder immersion while enhancing the breaking resistance.

Abstract: PURPOSE: To decrease power consumption and achieve the miniaturization of a camera by using a liquid crystal panel as a diaphragm device and setting the aperture by controlling the power supply to the picture elements of the liquid crystal panel.  
     CONSTITUTION: The liquid crystal panel consists of a plurality of circular picture elements 21, to each of which electrodes 22 and a common electrode 23 are connected. The liquid crystal panel has the characteristic that when it is applied with voltage it does not allow the transmission of light. This characteristic is utilized and applied to a diaphragm device. The brightness of the light 11 of a subject is sent as an analog signal of a photosensor 1 to an A/D converter 34. The A/D converter 34 sends the digital signal to an arithmetic processing unit 4. The arithmetic processing unit 4 determines proper aperture value based on various pieces of information and sends the signal to a liquid crystal panel control circuit 39. The liquid crystal panel 31 is divided to an open part 33 and a shut part 32 by the signal of the control circuit 39, by which the aperture is determined. The liquid crystal panel consumes electric power very little, and since it is lightweight and compact, the camera may be miniaturized.

Title: Tuner
Inventor: KOBAYASHI ATSUSHI
IPC: H04N5/44
Filed: 1977-10-17
Abstract: PURPOSE: To obtain a tuner, which requires neither a tracking adjustment nor an AFT circuit, operating ordinarily only when normal broadcast waves exist.  
     CONSTITUTION: With switch SW 1  closed, a sweep voltage is generated and with switch SW 2  closed at the same time, intermediate frequency oscillator 7 is operated, so that a signal from antenna 1 will be applied to frequency mixer circuits 4 and 8 via high-frequency amplifier circuit 2 whose tuning frequency is controlled by  sweep- voltage generating circit 3. In circuit 8, the output of oscillator 7 is mixed  with a high-frequency input signal and a sum-frequency beat component generated  as the result of it becomes equal invariably to a normal local oscillation frequency  which corresponds to the frequency of the high-frequency input signal. Therefore,  when the carrier frequency of a signal within the band of an input tuning circuit becomes equal to that of a normal video carrier signal, it agrees with one of frequencies at which a delay-line type oscillator can oscilate and driving delay-line type oscillator 9 by this output circuit causes a mode switching phenomenon, so that the  frequency of its oscillation will change from the prior frequency into another frequency close to a new frequency applied discontinuously

Title: Method for controlling opening and holding of automatic door
Inventor: YOSHIDA KENJI
IPC: E05F15/20
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To eliminate the inconvenience and the danger that an automatic door to be normally opened/closed is stopped in a door-opened condition by the manual operation of a passing person, and misunderstood to be failed, or a rebound door is unexpectedly closed when the door is powerfully and manually opened to keep the opened condition for carrying-in/carrying-out goods. SOLUTION: When a door is manually opened H1 from the low-speed door- open braking starting position P3 to the full-open position P4 during the general electric door opening operation, the door is electrically returned to achieve the low-speed door-closing D5. When the door reaches the low-speed door-open braking starting position P3, the normal door opening/closing operation is returned to be in the fully-closed condition. During the returned low-speed door- closing operation D5, if a worker for carrying-in/carrying-out goods intentionally pushes the door before reaching the low-speed door-open braking starting position, the door-open keeping condition is realized at a forcible stop position P8.  When the door is manually closed H2 after the working to the low-speed door-open braking starting position P3, it is returned to the general opening/ closing operation and controlled to be fully-closed condition.
