Abstract: PURPOSE: To provide a black-and-white, image or color image having high quality and good prereserving stability with an easy means by removing a reducing agent from a photosensitive layer simultaneously with or after heat development. CONSTITUTION: A heat developing photosensitive material having a photosensitive layer containing at least silver halide, a reducing agent, and a binder on a support body is image-exposed and heat-developed to provide an image. After the image is provided by the heat development, the reducing agent is removed from the photosensitive layer. As a method for removing the reducing agent, a dry treatment such as heating is preferably used, and the reducing agent is preferably transferred to a different layer from the photosensitive layer. In this case, it is required that the residual reducing agent is transferred to the different layer after worked as reducing agent as general. The different layer referred herein may be present on the same support body as the photosensitive material, or on another sheet.  After this treatment, it is required that the reducing agent left in the photosensitive layer is set less than 20 mole % of silver halide, and preferably less than 10 mole %.

Title: Operation control method for air compressor
Inventor: KAYAMA YUTAKA
IPC: F04B49/06
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To save energy in an air compressor by utilizing high-pressure air in its low-pressure side. SOLUTION: A high-pressure tank 12 in a high-pressure unit 10 and a low- pressure tank 22 in a low-pressure unit 20 are connected together by means of a connecting duct 30 with an outflow valve 31. The pressure in the high- pressure tank 12 is detected with a pressure sensor 18, which then outputs a detection signal and feeds it to a pressure controller 16. If the pressure in the high-pressure tank 2 falls within a set range, the controller 16 fully closes a blowoff valve 5 and then controls a suction valve 14 to set the pressure in the tank 12 to a predetermined pressure.  If the pressure in the high-pressure tank 12 exceeds the ceiling set value, on the other hand, the controller 16 sets the suction valve 14 fully throttling its suction quantity within avoiding a surge and then controls the outflow valve 31 to thus lead high-pressure air in the tank 12 to the low-pressure tank 22, which operation prevents a blowoff through the blowoff valve 15.

Title: Optical fiber laser device
Inventor: HORIGUCHI MASAHARU
IPC: H01S3/106
Filed: 1988-03-14
Abstract: PURPOSE:To output a train of optical pulses extremely narrow in width efficient ly by a method wherein an oscillating wavelength of an optical fiber laser is made to coincide very accurately with a wavelength (zero dispersion wave length) which makes a total dispersion of the optical fiber itself zero. CONSTITUTION:A double refraction Nd added optical fiber 12 is a core glass to which a rare earth element such as Nb is added, ferrules are fixed to the end faces of the above optical fiber, the ferrules are mirror-polished, and then a dielectric reflective film is formed thereon through a vacuum evaporation method. And, the device of this design is structured in such a manner that a zero dispersion wavelength of an optical fiber of a laser oscillator medium is made to coincide with a laser oscillating wavelength by deviation within + or -100Angstrom . And, the optical fiber has a double refraction of 5X10<-4> or more which is required for operating with a unipolarized wave for a laser oscillating wave length. First, a semiconductor laser 3a is driven by CW, oscillated laser rays are made to be incident on a Nd added optical fiber 1a through a rod lens 4b. Under this condition, an optical fiber laser grows to be in a CW oscillation state, then starts a high frequency signal generator 9 operating, and drives an LN optical modulator 5.

IPC: B60R7/06
Filed: 1982-04-09
Abstract: PURPOSE:To prevent the sudden release of a glove box, by controlling closing speed in the glove box with a closing speed control mechanism. CONSTITUTION:In the case where a glove box 4 is in a state of being fully closed, a swing arm 11 of a closing speed control mechanism 5a is pulled up by an energizing member 12 and engaged with the underedge upside of a cam hole 7a. Next, when the glove box 4 is unlocked, this box 4 gets opening with its dead load. If it reaches a half-opened state, the swing arm 11 is energized to rotate in a clockwise direction by guidance of the cam hole 7a and thereby receives powerful energizing force by the energizing member 12, and the other end 11b of this arm is more strongly pressed by the underedge of the cam hole 7a. As a result, frictional force in the other end 11b of the swing arm 11 against the underedge of the cam hole 7a increases, reducing the opening speed of the glove box 4, so that the crew aboard may escape from danger.

Filed: 1989-03-10
Abstract: PURPOSE:To obtain an appliance having excellent induced noise resistance by using a flexible printed circuit board made into the structure in which a head mounting part is bent, providing this wiring board with copper foil for grounding and packaging electronic parts thereon. CONSTITUTION:The head 2 is fixed by fittings 4 for mounting the head in an example shown in figure in which the flexible printed wiring board 1 having the copper foil on one surface is used. The electronic parts of head-up are packaged onto one surface of the wiring board 1 made into the structure in which the mounting part of the head 2 is bent. For example, a main IC 5 constituting a head amplifier circuit and peripheral parts 6 thereof are provided. A hatched part 3 is the grounding copper foil 3 for preventing the induced noises. The base film itself of the wiring board 1 is used as an insulating sheet by cutting off the copper foil corresponding to the terminal soldering part of the head. Since the terminal soldering part of the head 2 mounted to the wiring board 1 comes into contact with a metallic case 10 via the wiring board 1 in the sectional view after mounting to the appliance, the wiring board 1 from which the copper coil is cut off serves as an insulator to prevent the electrical shorting from the metallic case 10. This wiring board is connected by soldering to the main wiring board 7.

Title: Synchronizing circuit
Inventor: KARIYADO AKIRA
IPC: H04N5/04
Filed: 1980-05-01
Abstract: PURPOSE:To synchronize the counting operation in a counter circuit with a repetitive signal accurately, by resetting the counter circuit where reset pulses are generated most frequently. CONSTITUTION:Counter compensation circuit 17 generates reset pulses P2 and detects the generation positions of pulses P2 in the generation period of inhibition pulse P4 to detect where pulses P2 are generated most frequently. On the basis of this detected position, circuit 17 forces counter circuit 15 to reset. Therefore, reference pulse P3 generated by ROM circuit 16 is synchronized with a desired position of a TV signal. Once the counting operation of circuit 15 is corrected by circuit 17, circuit 16 supplies inhibition pulse P5 as a substitute for pulse P4. The time width of this pulse P5 is set nearly equal to the range of the shift of pulse P2. Therefore, if pulse P2 goes out of range of prescribed operation even after compensating circuit 15, it is compensated by circuit 17.
