Patent JP-S5930568-A (JP)
Title: Developing device
Inventor: TAJIMA HATSUO
IPC: G03G15/09
Filed: 1982-08-13
Abstract: PURPOSE:To reduce the size of a developing device and to provide stabilization in image density and the improvement in image quality, by constituting a titled device in such a way that a toner is scooped up and supplied into the narrow spacing between a developing roll and a toner well plate. CONSTITUTION:When a toner scooping body 6 is rotated in an arrow (b) direction, the horizontal part 9a of a member 9 agitates toner 4 while moving therein. An elastic body 9b carries the toner thereon up to the one end of a toner well plate 10 where said body forces further the toner into a gap (g). The toner 4a stored on the plate 10 is brought into contact with the surface of a developing roll 3 by which the toner is frictionally charged and is stuck on the surface of the roll 3. The stuck toner 4b is regulated to a prescribed thickness 4c by a member for regulating a toner thickness, i.e., a rubber blade 12, and is then transferred to a development part 13. A hopper, i.e., a developing device 2 is made smaller in size by the above-mentioned constitution and since the sticking of the toner onto the roll 3 is made uniform and stable, the image quality is improved.

Title: Driving method for pulse motor
Inventor: MAEDA YUTAKA
IPC: H02P25/066
Filed: 1986-06-17
Abstract: PURPOSE:To substantially eliminate hysteresis by arranging auxiliary coils near main coils in such a manner that the anxiliary coils generate magnetic fluxes in the opposite direction of those by the main coils. CONSTITUTION:An auxiliary coil, (a) adjacent to a main coil A is wound on a core C and in the same manner, an auxiliary coil (d) adjacent to a main coil B is wound on a core D. In this case, the numbers of turns of the auxiliary coils a and b are substantially smaller than the respective numbers of turns of the main coils A and B. After excitation by the main coils is completed, the auxiliary coils are excited so as to generate magnetic fluxs in the opposite direction of those by the main coils. As a result, residual magnetism can be avoided, and the hysteresis of a moving element can be eliminated.

Title: Signal input device
Inventor: KUWAKI KATSUHIKO
IPC: G06F9/48
Filed: 1988-06-07
Abstract: PURPOSE:To realize the generation of interruption signals as necessary by resetting a delay action via a delay circuit constituting each differentiation circuit with use of an interruption condition selecting signal and making a memory circuit store a differential output signal for output of this signal to an OR circuit and each AND circuit and at the same time resetting the memory circuit with an interruption inhibiting signal. CONSTITUTION:Each of delay circuits 10-1 to 10-n constituting the differentiation circuits 5-1 to 5n respectively contains a function which resets the delay actions with reception of an interruption condition selecting signal. At the same time, these delay circuits store the differential output signals received from the differentiation circuits to output these signals to the OR circuits 7-1 to 7-n and AND circuits 9-1 to 9-n respectively and also contain the memory circuits 11-1 to 11-n whose memory contents are reset with reception of an interruption inhibiting signal. If both the interruption condition selecting signal and the interruption inhibiting signal are insignificant, an interruption request is produced with the state change of an input signal. Thus the interruption condition selecting signal defined significant. As a result, an interruption request is produced only when the input signal has a rise change. Then the interruption request is not produced despite a state change recognized as long as a significant interruption inhibiting signal is available.

Title: Aluminum electrolytic capacitor
Inventor: KUNUGIHARA HIROSHI
IPC: H01G9/12
Filed: 1990-05-29
Abstract: PURPOSE:To prevent gas of driving electrolytic solution from flowing to the outside by providing a space part above an explosion-proof valve provided to a top board part of a metallic case, by providing a plurality of buffles inside the space part and by providing an absorbing material having an effect to absorb electrolytic solution. CONSTITUTION:Fiberglass, porous hypolymer, etc., are used as an absorbing material 10. When an overvoltage above the rated value is applied to an aluminum electrolytic capacitor, the internal pressure of a metallic case 2 rises, thereby allowing an explosion-proof valve 6 provided to a top board part 2a to start, and driving electrolytic solution in the inside ejects from the explosion- proof valve 6. In the process, most of gas of driving electrolytic solution hits a plurality of buffles 9, it is cooled and liquified, and drops on the top board part 2a of the metallic case 2. The remaining gas of driving electrolytic solution goes outside through a small hole 9a provided to the buffle 9; however, since it is absorbed by the absorbing material 10 provided to the outside of the buffle 9, gas of driving electrolytic solution can be prevented from flowing outside the capacitor.

During this, if a guide operates a decelerating button as the very important person forgets to bring something, the cage is retarded by a retarding circuit RT and stopped to the nearest floor. The cage is immediately reversed and returned to the starting floor, so that the return time is remarkably shortened to case the feeling of irritation of the very important person.

Title: Magneto-optic recorder
Inventor: YAKOBU MARIA FUAN NIYUURANDO
IPC: G11B5/02
Filed: 1989-06-05
Abstract: PURPOSE: To prevent deterioration in an S/N by providing a compensation device which changes a parameter to control a magnetic field generated by a coil according to correction signal so that a magnetic field strength of a thermo-magnetic layer does not depend on a position of this thermo-magnetic layer. CONSTITUTION: By adopting a current flowing in a coil 15 as a parameter, a compensation device is configured so as to operate in accordance with a prescribed function of the coil current 15. This configuration makes only a necessary current flow through the coil 15. The prescribed function, with the magnetic field assumed as a function of a distance, can linearly approximate the magnetic field to follow characteristic varying along the coil axis. Therefore, the current flowing through the coil 15 can be reduced, and the power consumption of the circuit dissipating the heat in the coil 15 and energizing a magnetic head can be suppressed. This prevents a deterioration of an S/N.

Title: Method for measuring index of refraction of prism
Inventor: TOMITA NORIKO
IPC: G01N21/41
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To easily form a prism and measure an index of refraction accurately by arranging a plurality of prisms of the same material having the same vertical angle in parallel to an optical axis of a measurement light to obtain a specific thickness and measuring the index of refraction. SOLUTION: A plurality of prisms of the same material having the same vertical angle are arranged in parallel to an optical axis of a refractive index measurement light to measure a refractive index. That is, a plurality of thin prisms are manufactured under the same conditions and bound. A total breadth (thickness) of the bound prisms is 5-20mm. A bright slit image is obtained if the thickness is at least 5mm or larger. The vertical angles of the prisms are necessary to agree with each other. Since the plurality of prisms bound to a required thickness are arranged to measure the refractive index, a width of a slit is increased and a brightness required for correct measurements is obtained. Accordingly, measurement accuracy necessary for measuring the refractive index of the prism is attained.
