Title: Micro-processing method
Inventor: YAMAZOE HIROSHI
IPC: H01L21/306
Filed: 1985-05-31
Abstract: PURPOSE:To prevent a resist film from exfoliating and a transparent conductive film from damaging by dipping a thin film formed by a sputtering method on a substrate in a mixture of aqueous organic acid solution and hydrogen peroxide water, thereby shortening a micro-processing time due to corrosion of the film. CONSTITUTION:A thin film is formed by a sputtering method with praseodymium oxide, manganese oxide or mixture of both as a target on a substrate. The film is dipped in a mixture solution of aqueous organic acid solution and hydrogen peroxide water. The aqueous organic acid solution is used as aqueous tartaric acid solution or aqueous citric acid solution, and the temperature of mixture is held at 50-80 deg.C. The micro-processing time based on corrosion of the film is shortened to prevent the resist film from exfoliating and a transparent conductive film from damaging.

Title: Resin composition for semiconductor sealing
Inventor: MURAKAMI SHIGERU
IPC: H01L23/29
Filed: 1990-05-09
Abstract: PURPOSE:To obtain a resin composition for semiconductor sealing having sufficient soldering-heat resistance, high flow and excellent cracking resistance and reliability of humidity resistance by mixing a specified polyether copolymer with an inorganic filler. CONSTITUTION:A resin composition prepared by mixing a polyether copolymer comprising repeating units of formula I and repeating units of formula II and having a content of repeating units of formula I {in terms of a molar ratio : (I)/[(I)+(II)]} of 0.15-0.4 and a melt viscosity of below 1000P at 400 deg.C and a shear rate of 1000sec<1> with 10-80wt.%, based on the polyether copolymer inorganic filler. When the compositional ratio of the repeating units of formula I is below 0.15, the glass transition temperature of the polyether copolymer is lowered and the heat resistance is lowered, or the melting point is increased and the moldability is worsened. When it is above 0.4, the crystallinity of the polyether copolymer is lost and the heat resistance and solvent resistance are worsened.

Title: Pressure detecting device
Inventor: KINOSHITA MITSUTAKA
IPC: G01L23/24
Filed: 1980-08-29
Abstract: PURPOSE:To obtain the titled device wherein errors are hard to occur in detected values by providing a responsive member which moves in response to the difference between free air pressure and the pressure in a hermetically sealed chamber wherein a specified pressure in the vicinity of the atmospheric pressure is maintained and detecting the displacement of the responsive member. CONSTITUTION:Under the operating state of an engine 2, a fuel injection device 22 injects the fuel which is proportional to the flow of suction air based on the signal of a flowmeter 18, and controls the amount of fuel injection in response to the opening degree of a throttle valve 26, the speed of a vehicle and the like. Furthermore, a signal from the pressure sensing device 30 is supplied to a control device 20 which controls the fuel injection device 22. The quantity of the suction air sensed by the flowmeter 18 indicates the flow rate by volume, and the flow rate signal is compensated to indicate the flow rate by weight. In comparison with the conventional vacuum type pressure detecting device, the pressure difference acting on a pressure sensing element 38 is very small. Therefore, even though minute pin holes are generated in a silicon diaphragm 44, the pressure in the hermetically sealed chamber 42 is hard to vary, and the faults against the pressure detecting function is hard to occur.

Title: Oil pressure conversion type air cylinder
Inventor: KIKUCHI NOBUMI
IPC: F15B15/22
Filed: 1978-09-29
Abstract: PURPOSE: To improve the stability of a generated oil pressure by conducting a rapid feed by an air cylinder, conducting boosting by a hydraulic cylinder, and avoiding the contact between air and oil.  
     CONSTITUTION: An air pressure is fed from a port A formed in a cylinder cover 24, and a port B is opened into the outside air. At this time, oil supply is cut off, and a piston 2 and a piston rod 3 descend rapidly. Attending on the descent of an intermediate cylinder 7, a negative pressure develops in an intermediate hydraulic chamber 20, and the oil flows into the chamber 20. When a high-output ram 8 and the cylinder 7 having descended rapidly together with the piston rod 3 collide with a work, the oil 4 in a high-oil-pressure generation chamber 10 is pressurized by the cylinder rod 3, cuts off the back flow of the oil 19, locks the cylinder 7, and pushes down the ram 8 with a high output, so that the contact between air and oil is avoided.

Filed: 1990-05-10
Abstract: PURPOSE:To obtain a photosetting adhesive which can join not only transparent materials but also translucent materials readily and rapidly by compounding a radical-polymerizable vinyl compound, alpha-diketone and a specific sensitizer. CONSTITUTION:A radical-polymerizable vinyl compound [e.g. 2-hydroxyethyl (meth)acrylate], alpha-diketone (e.g. camphor quinone) and a sensitizer of the formula (wherein Q<1> and Q<2> each independently represent a dialkylamino group being linked to the o-, m- or p-position with respect to the carbonyl group) [e.g. 4,4'-bis(diethylamino)benzophenone] are compounded to obtain a photo-setting adhesive. This adhesive can be cured not only by exposure to UV rays but also by exposure to visible rays, and therefore, it can exhibit higher sensitivity and attain higher adhesive strength when employed in joining translucent materials which do not transmit UV rays and transmit only visible rays, ceramics such as alumina and silica, and plastics containing a pigment or a ceramic filler.
