Patent JP-H05153773-A (JP)
Title: Dc-dc converter
Inventor: MASAMOTO KAZUHIKO
IPC: H02M1/08
Filed: 1991-11-26
Abstract: PURPOSE:To enable high frequency switching operation by providing a gate circuit, which quickly discharges the charges accumulated in a gate capacitance of MOSFET during the discharging operation, in a converter comprising an inductor which conducts charging operation when a main switch element MOSFET is in the on-state and a discharging means which conducts discharging operation when the main switch element is in the off-state. CONSTITUTION:When an output of a control IC14 turns off, charges accumulated in a gate capacitance of a P-channel MOSFET 3 applies a forward bias to a transistor 10 through a resistor 11, a base current to the transistor 10 and discharges quickly by turning on the transistor 10. As a result, a gate-to-source voltage of the P-channel MOSFET 3 quickly becomes lower than the cut-off voltage and the P-channel MOSFET 3 turns off. As described, the main switch element P-channel MOSFET 3 turns off quickly through a gate discharge circuit, providing the effect that the high switching frequency can be obtained.

Abstract: PURPOSE:To improve the working speed, by providing a grip bracket movable back/forth and up/down with respect to a unit table while arranging a lifting/ lowering mechanism and a forward/rearward motion mechanism therefor between said grip bracket and the unit table, and arranging a nut support near stud bolts arranged in work symmetry. CONSTITUTION:When a nut G is removed from a stud bolt F, the nut G is rotated and released from screwed condition, while a unit table 7 is set near said nut G and a grip bracket 18 is advanced to the lower position of the nut through operation of a forward/rearward motion mechanism 20. Then the grip bracket 18 is lowered through operation of a lifting/lowering mechanism 19 to such a washer H as required, thereafter the grip bracket is lifted to removed the nut G and the washer H from the stud bolt F. Then the nut is engaged with a nut support 21 through operation of the forward/rearward motion mechanism 20 and the lifting/lowering mechanism 19, and only the grip bracket 18 is removed. When the nut G is fitted over the stud bolt F, said sequence is reversed.

Title: Lighting device for discharge lamp
Inventor: TAKEDA TETSUSHI
IPC: H05B41/24
Filed: 1987-12-09
Abstract: PURPOSE:To facilitate the discrimination and improve ease of maintenance of a discharge lamp by causing to function an informing circuit, which does not control the oscillation of an inverter circuit when the last stage in the life of the discharge lamp is detected, by means of pover of commercial dc power source and by causing a display lamp provided in the informing circuit to light. CONSTITUTION:A detection coil 5 and a detection circuit 7 detect the life of a discharge lamp 6 by capturing a voltage rise on time secondary side of an oscillation transformer 14 based on half-ware discharge phenomenon of the discharge lamp 6. An informing circuit 14 is actuated by receiving a trigger output issued when the detection circuit 7 detects the life of the discharge lamp 6, and causes a display lamp 42 to light. At the same time, the discharge lamp 6 continues the lighting condition with the half-wave discharge even in the last stage of the life of the lamp 6. Since the power source of the informing circuit 41 which informs the life by lighting the display lamp 12 comes from a commercial power source 1, the informing circuit 41 continues to inform of the location of the discharge lamp 6 even if a wall switch 2 is turned off after the functioning start of the informing circuit. This improves the ease of maintenance of the discharge lamp.

Title: Instruction processing method and instruction processor
Inventor: IMAI TORU
IPC: G06F9/38
Filed: 1988-12-09
Abstract: PURPOSE:To attain continuous processing by providing plural prefetch buffers, housing the instruction of a branch destination to the designated prefetch buffer according to a computer instruction, and designating the prefetch buffer to be next read when a branching instruction is executed. CONSTITUTION:By executing the first instruction before the branching instruction, the instruction of the branch destination can be prefetched in advance to one designated prefetch buffer (the prefetch buffer not to be used for normal prefetch processing) out of plural prefetch buffers 41-4n. By using the second instruction as the branching instruction, the prefetch buffers 41-4n to already prefetch the instruction are designated and the instruction of the branch destination can be immediately sent to an instruction decoding part 6. Thus, the continuous instruction processing can be attained without being interrupted when the branching instruction is executed. Then, a processing speed can be improved.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of a white region around spacer due to abnormal orientations of liquid crystal and to obtain a liquid crystal display element having good display quality, by using a spacer for liquid crystal display element having a specific volumetric resistivity or above. SOLUTION: The spacer 9 for liquid crystal display element has a volumetric resistivity of >=10<15> Ω.cm. Consequently, the electrification property thereof is high and the orientation of liquid crystal molecules having strong polarizable property perpendicular to the surface of the spacer 9 by electrical attraction or repulsion, is made possible, thereby, the abnormal orientation is prevented. In such a case, insulating films 11 are formed respectively on the opposite surfaces of a pair of transparent electrodes 10 and for example, transparent conductive films 12 are patterned and formed by photolithography on the insulating films 11 of the respective substrates 10. Oriented films 13 consisting of, for example, polyimide films, are formed on the transparent conductive films 12 of the respective substrates 10.  Next, the spacers 9 for the liquid crystal display element are sprayed on the oriented films 13 of the substrates. Adhesive layers are, thereafter, formed in the peripheral parts on the circumferences of the substrates by using sealing materials 14 to stick the substrates to each other.

Filed: 1993-12-13
Abstract: PURPOSE:To provide a compactness of an upright type and the touch feeling of an acoustic piano by combining an upright type acoustic piano with a reproducing system in an electronic piano. CONSTITUTION:This piano is constituted of an acoustic piano part AP and an electronic piano part EP. Then, when a key board 11 is operated, a musical tone (acoustic piano sound) is generated from a well-known acoustic sound generation mechanism generating sound by operating the strings with external force by depressing a key. On the other hand, key sensors 21, 22 detect an operation condition and the strength of a touch when the key board 11 is operated. A musical tone generation part 33 reads out a storage content in a sampling waveform ROM and generates electronically a musical tone waveform based on the information of the interval and the strength, etc., of the musical tone to be performed, and the generated musical tone (electronic piano sound) is generated from speakers 55a, 55b. Thus, since a high-pitched band component is generated simultaneously, tone quality and extent like a ground piano are obtained.

Title: Curved honeycomb structural body
Inventor: MACHIDA MINORU
IPC: F01N3/28
Filed: 1992-11-20
Abstract: PURPOSE:To provide a curved honeycomb mold body where the flow rate of fluid which comes in from one end face, and comes out of the other end face through through holes, is uniformly distributed. CONSTITUTION:The curved honeycomb mold body 8 in an ellipse shape in cross section while each cell is in a square shape, includes a plurality of through holes (curved passage) 14 which are penetrated through from one end face to the other end face. Each through hole 14 is formed into a partition composed of inner walls 12 extended in the radial direction and inner walls 10 extended in the major axis direction of the aforesaid ellipse. In this case, a pitch Py between bulkheads, that is, the adjacent inner walls 10 and 10 forming each through hole 14, is so set as to be made gradually small at a linear rate or stepwise as it goes from the inward diameter side to the outward diameter side. Each through hole 14 is in a square shape in cross section. A pitch Px between the bulkheads in the direction perpendicularly intersected with the radial direction over a cross sectional surface is kept constant. By this constitution, when fluid comes in the curved honeycomb mold body from one end face, and comes out of the other end face through the through holes 14, the flow speed can thereby be uniformly distributed over the end face from the inward diameter side to the outward diameter side.
