Title: Activating method for alloy for occluding hydrogen
Inventor: ONO SHIYUUICHIROU
IPC: C01B3/00
Filed: 1981-12-07
Abstract: PURPOSE:To reactivate an alloy for occluding hydrogen by simple operation  when the performance of the alloy is deteriorated by repeating the occlusion and  release of hydrogen, by treating the alloy under pressure of hydrogen other than stationary running conditions. CONSTITUTION:A heat exchange tube 5 through which a heat medium from a process P is passed is installed in a regenerator 1 packed with an alloy for occluding hydrogen such as an Ni-Mg alloy. The regenerator 1 is connected to a tank 2 foe storing hydrogen with piping 3a, 3b to form a heat controller for the process P in which a surplus of heat and demand for heat are repeated at certain time intervals. When the heat medium in the process P has an excess of heat, hydrogen in the alloy is released by heating with the heat and the medium is cooled. The released hydrogen is fed to the tank 2 with a compressor 4. When the heat medium requires heat, hydrogen is occluded in the alloy and the medium is heated. When the performance of the alloy is deteriorated by repeating  said operations, by closing a valve V5 and opening a valve V6, the heat medium  is bypassed, and by evacuating the regenerator 1 or feeding highly compressed  hydrogen, the alloy is reactivated.

Filed: 1992-06-30
Abstract: PURPOSE:To calculate the porosity and pore size of a solid material accurately according to a specific formula pertaining to pore properties in the solid material by utilizing an ultrasonic wave. CONSTITUTION:A pair of ultrasonic sensors are set up at both ends of a solid material, while an ultrasonic wave is transmitted out of the sensor on one side and the response waveform is detected by the sensor on the other. In succession, the detected waveform is subjected to reverse convoluted integral processing by comparison with the response waveform obtained out of a solid material sample piece of the same material, where no pore exists at all, and thereby a pore function to be expressed in an equation I is found out. In this equation, tp shows propagation delay time in the pore function, tw is half-value width of each pore, H a peak value of the pore function, respectively. A graph, using axis of abscissa for the time, axis of ordinate for the pore function respectively, is drawn up, finding out tp, tw and H from this graph. In addition, porosity psi and means pore radius (r) are found out of functional equations II and III of pore properties. In the equations, Vp shows sound velocity of an incident wave, Vc the sound velocity of a bypass wave (a wave advancing along a pore surface), L a propagation distance of wave motion, respectively. With this constitution, the porosity and the pore radius can be sought without being swayed by material quality, form and measuring conditions.

Title: Photographic film cartridge
Inventor: MIZUNO KAZUNORI
IPC: G03C3/00
Filed: 1990-07-26
Abstract: PURPOSE:To surely send a film out and to completely cut off light which is made incident from a port slit by providing a light shield member which is elastic and projects inside a cartridge main body in a film passage in a film winding direction. CONSTITUTION:The light shield member 17 is fixed to a lower cartridge 12 at the position where the film 13 moves to the port slit 15. This light shield member 17 is formed by implanting rayon pile electrostatically on both surfaces of a polyester base and projects in the film take-up direction. Consequently, the light shield member covers the rolled film while contacting either or both of the base surface and emulsion surface of the film, so the light which is incident from the port slit is cut off not to fog the film with the light. Further, the light shield member is elastic and varies according to the movement of the film and the resistance between the sent-out film and light shield member does not become so large, so that the film can securely be sent out.

Abstract: PURPOSE:To prevent the deterioration of an output potential waveform by connecting an in-phase input and the output of an inversion amplifier, and connecting the output of a direct current amplifier to connect a reverse phase input to a reference input to the reverse phase input of the inversion amplifier through a third resistance. CONSTITUTION:To the drain of an electric field effect transistor 2, a load resistance 3 and the in-phase input of an inversion amplifier 9 are connected, and the output of a direct current amplifier 13 to connect the reverse input to a potentiometer (reference input) composed of a variable resistor 12 is connected to the reverse phase input of the inversion amplifier 9 through a resistance 11. Even when the light input level inputted to the pin photo diode 1 is increased, the direct current potential of the output terminal 8 is constantly kept by the direct current feedback circuit composed of the direct current amplifier 13 and resistances 10 and 11. Thus, as the light input level is increased, the direct current potential of the output terminal of the light receiving circuit is changed and the deterioration of the waveform is inhibited.

Title: Head access controlling device for magnetic photographic printing apparatus
Inventor: KOKAJI TOKUO
IPC: G03G19/00
Filed: 1988-08-11
Abstract: PURPOSE:To prevent flawing deeply even through a recording head collides against a magnetic drum by any chance by a method wherein sub scanning in a magnetic drum axial direction with a recording head is started by a sub scanning means before the recording head reaches a recording position of the magnetic drum. CONSTITUTION:When a state capable of writing comes by a start of rotation of a magnetic drum 1, an arm 3 pivots by using a pin 4 as a fulcrum by solenoidal excitation to push an access shaft 8 out to the magnetic drum 1 side via a stop pin 5. The pin 5 stops by fitting into a V groove 10, and a magnetic head 15 installed to a top part of a plate spring approaches the magnetic drum 1 via an air damper 16. In that case, carriage 17 is pulled with a wire 53 by drive of a sub scanning motor before the magnetic head 15 reaches a recording position, and electrification of the magnetic head 15 is controlled while the carriage 17 is being moved along guides 18, 19 to form a magnetic latent image on the magnetic drum 1. Thus, even though the magnetic head collides against the magnetic drum by any chance, since its position differs each time, flawing deeply can be prevented.

Abstract: PURPOSE:To detect the abnormal short circuit readily by generating the warning when the abnormal short circuit occurs in the electronic balance, and preventing the double operations of a warning device and a computing device by using interrupting means. CONSTITUTION:When a key in an input device 1 is locked to an ON state before a power source is turned ON or by some cause during the operation, the warning device 4 is operated by a warning command signal S4. When the warning device 4 is linked with a display device 5, the operation of the computing device 2 is concurrently stopped by an interruption command signal S'2 from an interruption command means 8. Even though the short circuit has occurred, and a timer is returned to the original position within a specified time, the computing device 2 is operated by a computation command signal S2 at that time point, and the timer 71 is concurrently reset by a stop command signal S''4. Thus a normal mode is restored.
