Title: Switching power circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M7/12
Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for improving the breakdown voltage of a smoothing capacitor on primary side by preventing a rise in DC input voltage at no-load. SOLUTION: The power-factor improved circuit of a composite resonance converter is formed, so that a switching pulse is transmitted from a tertiary winding wound around an insulated converter transformer via a series resonance capacitor CA to a primary winding NP of a magnetic coupling transformer MCT. The secondary winding NS of the magnetic coupling transformer MCT is in a rectified current path, therefore the switching pulse is ultimately fed back to the rectified current path via the magnetic coupling of the magnetic coupling transforme MCT.  Although the feedback output permits rectified current to be interrupted by means of a high-speed recovery type rectifier diode D2 to improve power factor, and even while the high-speed recovery diode D2 is not being conducted, resonance current is fed to charge a smoothing capacitor by causing AC current over an entire period by means of the resonance operation of the series resonance capacitor CA and the primary winding NP.

Title: Sliding material
Inventor: ITO KATSUTO
IPC: F16C33/12
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To obtain a sliding property with an excellent initial conformable property, and an excellent abrasion-proof property. SOLUTION: This sliding material 1 furnishes a Cu plating layer 3 formed on a base member, and an Sn or Zn plating layer 4 or an alloy plating layer of them. Such a plating layer 4 is soft and has an excellent conformable property. And when a friction heating is generated by sliding with the opponent material, the Cu plating layer 3 and the plating layer 4 generate a diffusion reaction by the friction heating, and an alloy layer including the alloy (bronze) of the Cu and the Sn, or the alloy (brass) of the Cu and the Zn is formed between both layers. Consequently, since an alloy layer 5 of the bronze or/and the brass is exposed in the sliding surface when the abrasion of the plating layer 4 progresses, a sliding property with an excellent abrasion-proof property can be obtained by the alloy layer 5.

Title: Thyristor exciting device for synchronous machine
Inventor: SHIBATA MASAHIKO
IPC: H02P9/30
Filed: 1994-10-07
Abstract: PURPOSE: To enable a control system to obtain the optimum stable response even when either one of an auxiliary exciting power source and main exciting power source is used by setting the optimum control gain to each power source when each power source is operated. CONSTITUTION: A control gain function setter 32 respectively sets in advance optimum control gain functions corresponding to a main exciting power source and auxiliary exciting power source. A control gain function selector 33 selects the control gain function corresponding to one of the exciting power sources selected through a switch 13 from the setter 32 and uses the function as the specific control gain function of a voltage adjuster 31. When a synchronous machine is operated by using the auxiliary power source, the selector 32 sets the optimum control gain function of its control system to the adjuster 31 and, when the machine is operated by using the main exciting power source, the setter 31 sets the optimum control gain function of its control system to the adjuster 31.  Therefore, the occurrence of such a case that the control characteristics of the control systems become unstable or the responses of the systems become slower can be prevented.

Title: Hydrogen storage electrode and manufacture thereof
Inventor: FURUKAWA ATSUSHI
IPC: H01M4/26
Filed: 1989-10-16
Abstract: PURPOSE:To lengthen the life of a hydrogen storage electrode independently of the kind of hydrogen storage alloy by forming the hydrogen storage electrode with composite powder of hydrogen storage alloy powder and carbonyl nickel powder, which covers the hydrogen storage alloy powder, with chain structure numerously branched in the three-dimensional direction. CONSTITUTION:A hydrogen storage electrode is formed mainly with composite powder of hydrogen storage alloy powder and carbonyl nickel powder, which covers the hydrogen storage alloy powder, with chain structure numerously branched in the three-dimensional direction. Since the composite powder is three-dimensionally connected each other with the three-dimensional chain structure of the carbonyl nickel powder, the conductivity of the electrode is increased, and stress caused by the expansion and shrinkage of the hydrogen storage alloy particle attendant on repeated charge-discharge is eased, and the generation of cracks and powderization of the hydrogen storage alloy particle are retarded. The cycle life of the electrode can be increased.

Title: Image density control system
Inventor: TONOMOTO YOSHIHIRO
IPC: G03G15/09
Filed: 1985-11-29
Abstract: PURPOSE:To improve the detection sensitivity of a density variation by recording the density of a density mark which is formed on a photosensitive body by a lower density than an image density of an image recording area. CONSTITUTION:A laser beam for scanning a density mark area 5, among scanning laser beams is reflected by a polygon mirror 2, and thereafter, set to an exposure quantity by which a density mark goes to a density area in which the detection sensitivity of a density variation is improved, by an optical filter 6 for absorbing the laser beam in a prescribed ratio, and projected to a rotary photosensitive drum 3. Accordingly, a latent image of the density mark is formed by an exposure quantity being weaker than a necessary image, and the density mark which is developed by a developer by using a developing device 7 is deviated to a lower density than a necessary image. As for the detection sensitivity of a sensor for detecting a density variation, it is higher in a low density area, therefore, a control input becomes larger and the density can be controlled exactly.

Title: Electron-beam pulse generator
Inventor: BUIRUHERUMU SHIETSUFUERUSU
IPC: H01J37/04
Filed: 1990-10-08
Abstract: PURPOSE: To avoid transverse movement of a main focus with respect to the beam axis by furnishing a deflection device between two lenses, and installing an electron beam stop between the deflection device and the second lens. CONSTITUTION: An electron beam 2 is passed through a beam stop part 11 and focused by a deflecting device 9 onto a processing region of a row works 7 or in its neighboring area. If the energy to work within the processing region is transmitted in the beam working time, the beam 2 is deflected to the stop 10 by the deflecting device 9. Because the intermediate focus 4, focus of lens 5, and the working focus 6 lie on a straight line, electron beam fluxes advancing from the focus 4 in different directions reach the same focus 6 after passage of the lens 5. The device 9 is accurately positioned at the focus 4 and performs deflection of the beam 2. This permits avoiding the transverse movement of the main focus with respect to the beam axis.

Title: Picture signal processing unit
Inventor: KUROSAWA TOSHIHARU
IPC: H04N1/40
Filed: 1987-10-23
Abstract: PURPOSE:To improve the picture quality by magnifying again a binarized picture with respect to a picture signal reducing a multi-value picture signal by arithmetic means so as to bring the area of white and black picture element into one picture element or over thereby improving the gradation characteristic. CONSTITUTION:An input picture signal is reduced by arithmetic means at a main scanning signal 1/2 reduction circuit 2 and converted into a binary signal by a random dither binarizing circuit 3. Then the main scanning signal is magnified by repeating two picture elements at a main scanning signal double magnification circuit 4 and decoded into the original size. Thus, the minimum black/ white picture element is selected to be one picture element or over and consecutive gradation characteristic is obtained even when the signal is recorded by a conventional laser printer. Since only the main scanning picture element is subject to reproduction/magnification and recovery, the deterioration in the resolution of the picture is less. Thus, the gradation characteristic is improved and the picture quality is improved.
