Title: Switching power source
Inventor: SENBA KAZUHISA
IPC: H02M3/28
Filed: 1989-05-18
Abstract: PURPOSE:To improve voltage variation characteristic by detecting the current of a choke coil of a main DC output circuit, and raising the switching frequency of a switching element when the detected current is small. CONSTITUTION:A choke coil 43 of a main DC output circuit 40, a current detector 60, and a frequency modulator 70 for raising the switching frequency of a switching element 20 when the detected current is small are provided. Accordingly, when the current of the coil 42 becomes a small value near a critical point, the modulator 70 is so operated as to raise the switching frequency of the element 20. When the frequency is raised, the coil 42 is held in an operating range not exceeding a critical point. Thus, the ON/OFF ratio of the element 20 is not varied, and the output voltage of a sub DC output circuit 40, out of detection of the output voltage is held substantially at a predetermined constant voltage. In this manner, even if the current of the circuit 40 is lowered, the output voltage of the circuit 40' is not lowered, thereby improving its voltage variation characteristic.

IPC: F01L1/34
Filed: 1981-08-12
Abstract: PURPOSE:To obtain high efficiency and safety through entire running conditions by making a cam shaft movable with respect to a crank shaft while an engine is in operation. CONSTITUTION:The opening or closing time of a suction valve 7 and an exhaust valve 8 with respect to the rotational angle of a crank shaft 7 is made variable in response to the detected result of a detector 10 which detects the running conditions of an internal combustion engine. For example, a regulating mechanism in which a sliding block 9' is inserted into a cam shaft sprocket 5 in freely slidable manner is provided, and the cam shaft 4 is designed to be movable with respect to the crank shaft 1 while the engine is in operation. The sliding block 9' moves in the axial direction by controlling apparatus 13 connected to the detector 10 along a peripheral groove 12. Upon this occasion, the cam shaft 4 is relatively rotated with respect to the cam shaft sprocket 5 by a slant spline to vary a phase angle with respect to the crank shaft 1. Thus, the valve opening or closing time in accordance with the speed can be selected and a high efficiency can be obtained.

Title: Path correcting method for robot
Inventor: RENBUTSU TATSUYA
IPC: G05B19/42
Filed: 1989-05-19
Abstract: PURPOSE:To simplify the work by correcting plural points of the front and the rear, as well at the time of correcting one point. CONSTITUTION:Teaching data stored in a controller C for controlling a robot body R is brought to one point correction by an operator. The correction quantity of the corrected point Pk is calculated, and a point number (n) is set. A distance L between the point Pk and Pn is calculated. Whether a position of the point Pn is within a correction range determined in advance or not is decided. When a result of decision if 'YES', a correction coefficient is calculated from the distance L between the point Pk and the point Pn and the correction range. The correction of teaching data of the point Pn is executed, based on the correction coefficient. In such a way, by a correction curve based on a correction pattern stored in advance, teaching data of the point being adjacent to the point Pk is corrected automatically. Accordingly, the teaching data can be corrected in a short time, and it becomes unnecessary to correct data by an expert.

Filed: 1979-10-03
Abstract: PURPOSE: To obtain a proper molding continuously by regulating working oil and heat medium in the manufacture of a plural number of resin moldings by using molds with plural cavities.  
     CONSTITUTION: Using the mold 1 with plural cavities 3a, 3b, and 3c, plural resin moldings are injected concurrently.

Title: Thermal lithographic original plate
Inventor: YAMANE SHIRO
IPC: B41N1/14
Filed: 1988-05-24
Abstract: PURPOSE:To improve the attaching property of ink thereby, to obtain a clear printing image without ground staining, by rendering the smoothness of the surface of a heat-sensitive recording layer not lower than a specified value measured by an Oken type smoothness gauge. CONSTITUTION:A heat-sensitive recording layer mainly composed of an inorganic pigment, a binder and a thermally-melting substance is formed on a water-proof support body. The surface of the recording layer is set to have a smoothness not smaller than 2,000sec. measured by an Oken type smoothness gauge. This is because the recording layer can be tightly adhered to a thermal head, and therefore a high quality printing image can be formed when a printing plate is formed. In order to obtain the smoothness not smaller than 2,000sec., the surface of the recording layer should be subjected to a calender treatment when a printing original plate is manufactured. A paper which has the wet strength increased by a thermosetting resin or the like, a synthetic resin film, a melting vaporized paper etc. can be used for the water-proof support body. Zinc oxide is preferable for the inorganic pigment from the viewpoints of its effectiveness and heat sensitivity. For the binder, it is preferable to use, for example, polystyrene, styrene-acrylic acid ester copolymer or the like that has a softening point or melting point not higher than 150 deg.C by the ring and ball method, and for the thermally-melting substance, kinds of wax which are melted at 50-200 deg.C, polyhydric alcohol higher fatty acid ester etc. are suitable.
