Title: Polishing method
Inventor: TANI YASUHIRO
IPC: B24B37/00
Filed: 1985-03-22
Abstract: PURPOSE:To enable polish to be precisely finished with high efficiency by polishing a mixture having bendolar or funicular region in which grains and liquid are filled and mixed with a polishing layer obtained by dry or semi-dry system molding. CONSTITUTION:About 1-30mum of grains like diamond and liquid like water or alkali solution are filled and mixed. The mixture is polished by the use of abrasives molded by dry or semi-dry system compression. Then, the filled and mixed condition is made of bendolar region in which liquid is annularly discretely attached around the contact points of grains while an air layer continuously exists or funicular region in which liquid is enclosed by surfaces containing the contact points of grains and exists continuously while the air layer discretely exists. Thus, in the polished cylinder 2B made of acryl resin, a grid 1 is projected over the whole polishing surface 3B as it is and even in the peripheral edge the line 1'' of the grid 1 is projected approximately as straight line. Thus, precise finish polishing can be performed with high efficiency.

Abstract: PURPOSE:To prevent SOG films from being excessively removed through hydrofluoric acid cleaning and maintain flatness by applying a SOG film to an insulating film twice, performing firing and heat treatment to densify the SOG films, and sufficiently reducing etching rate. CONSTITUTION:An insulating film 3 of 100-300nm in thickness is deposited by a CVD method on a semiconductor substrate 2 having a first layer wiring 1 formed thereon.

Abstract: PURPOSE:To obtain the focus detecting device of high accuracy for allowing the improvement of automatic focusing accuracy and the reduction of overall length to coexist with each other by attaching externally an image-forming lens to the vicinity of a photographic lens, interlocking a focusing use lens group moved at the time of focusing of the photographic lens and a part of a focus detection use optical system, and executing the decision and detection of focusing of the photographic lens. CONSTITUTION:An image forming lens does not utilize a photographing optical system, and an image forming lens 1 being a separate body from photographic lens is attached externally in the vicinity of a photographic lens, so that a focusing use lens group moved at the time of focusing of the photographic lens and a part of a focus detection use optical system are interlocked, and so that focusing of the photographic lens can be decided and detected by the focus detection use optical system. The accuracy is determined by four parameters of FP, beta, (f) and fAF. In this regard, FP, beta, (f) and fAF denote an F-number at the time when a principal ray of a re-image forming lens passes through the image forming lens 1, paraxial magnification of a condenser lens 3 and a re-image forming lens 5, a focal distance of the photographic lens, and a focal distance of the image forming lens 1, respectively. This automatic focusing system can set the parameter independently from the photographic lens. In such a way, the focus detecting device being compact and having high accuracy is obtained.

Title: Semiconductor circuit
Inventor: SAKAMOTO MITSUZO
IPC: H01L21/8234
Filed: 1989-03-10
Abstract: PURPOSE:To enable detecting a load current, even if a circuit is in a reflux mode, by connecting a current-sensing MOS transistor in parallel with a current- monitoring MOS transistor and by preventing a reverse current from flowing through said current-monitoring MOS transistor. CONSTITUTION:When N-channel MOS transistor 4 is in the ON state, a current flowing through a load is equal to the total of drain currents of N-channel MOS transistors 2 and 3, and the drain current of said N-channel MOS transistor 3 can be monitored with a sense voltage VS generated in a sense resistor 9. When the N-channel MOS transistor 4 is turned OFF, the current flows through the sense resistor 9 because the body of sense FET 3, 6 is connected with VGND via diode. Thus, a load current can be detected, even after the N- channel MOSFET 4 changes in the OFF state.

Abstract: PURPOSE:To always perform adequate ignition timing control and improve performance of full load operation especially at low temperature, by obtaining a basic advance angle value from detection of engine speed, load, etc. and providing a correction means holding the basic advance angle value to at least a required value for an engine at low temperature. CONSTITUTION:Each output signal S1-S4 of a temperature sensor 1, intake negative pressure sensor 2, reference angle sensor 3 and unit angle sensor 4 is input to an arithmetic device 6 through an input/output control device 5.

Title: Operation of galvanic battery type oxygen sensor
Inventor: FUJITA YUUKOU
IPC: G01N27/49
Filed: 1984-03-24
Abstract: PURPOSE:To contrive to prolong the life of an oxygen sensor by conserving the discharge quantity of electricity of a negative pole active substance, by connecting a resistor larger than a normal resistor at the time of use when the oxygen sensor is not used over long period of time while connecting the normal resistor at the time of continuous use. CONSTITUTION:When an oxygen sensor 1 is not used for a long period of time, a switch 8 is turned ON and, at the time of normal use, a switch 7 used at the time of normal use is turned ON. When the quantity of an electrolyte is set to 1/10 that of a practical product and the comparison test of the life of the sensor is performed by this inventive operation method A and a conventional operation method B, the result shown by the drawing is obtained. This drawing clearly shows that the discharge quantity of electricity of lead is reduced in the case of A because a small current is flowed during the operation of the oxygen sensor by a resistor having a resistance value larger than that of a normal resistor when the switch 8 used at the time of non- use is turned ON on the supposition for the time of non-use. By conserving the discharge quantity of electricity of a negative pole active substance as mentioned above, the life of the sensor can be made longer.
