Title: Formation of solder mask
Inventor: KANEMITSU KINICHI
IPC: C25D5/02
Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To prevent the short circuits between circuits caused by solder and to obtain excellent thermal resistcance, chemical resistance and weather resistance by forming chromate films on a wiring circuit by electrolytic chromate treatment, and using the films as solder masks. SOLUTION: Plating-resistant protecting masks 15 are formed on parts 16, on which solder is deposited, and plating lead parts 13 of a wiring circuit 12 in a wiring board 11, and electrolytic chromate treatment is performed. Thus, black chromate films (solder masks) 14 are formed on the exposed conductor part. Then, the plating-resistant protecting masks 15 are removed, and an etchingresistant mask is formed on the wiring circuit part other than the plating lead parts 13. Thereafter, the plating lead parts 13 are etched, and a wiring circuit board 10 having the plating leads is obtained by removing the etching- resiscant mask. Thus, the short circuits between the circuits caused by the solder can be prevented and excellent thermal resistance, chemical resistance and weather resistance can be obtained.

Filed: 1983-10-27
Abstract: PURPOSE:To conduct shift operation gently by changing a throttle for exhaust from a cylinder device for shift operation at least by two stages in the course of shift operation and varying change timing according to the rev count of an engine. CONSTITUTION:When a change lever 4a of a command unit 4 is operated, a command signal is sent out to a control unit 3, thereby to switch one of solenoid valves 5, 6 to the exhaust state and to control one of variable throttle solenoid valves 7, 8, so that only during an initial little time, a quick exhaust is performed through a valve portion 7b having a large throttle, and then a valve portion 7a having a small throttle is used to perform slow exhaust. When the initial stage of shift operation is completed, the valve portion 7b is again used to conduct quick exhaust. If a valve of engine revolution number related velocity detected by a velocity sensor VS is low, in a short time, the valve portion 7b is switched to the valve portion 7b to complete shift operation more quickly than during high-speed running.

Title: Method for pulling up single crystal
Inventor: KATAYAMA SHUJI
IPC: C30B15/36
Filed: 1986-08-29
Abstract: PURPOSE:To obtain a high-quality single crystal with less cracks generated in good yield by using a seed crystal formed from a crystal having orientation different from that of the grown crystal as the seed crystal in the Czochralski method. CONSTITUTION:A seed crystal formed from a crystal having orientation different from that of the grown crystal is used as the seed crystal to be used for crystal growth in the method for pulling up a single crystal by the Czochralski method.

Title: Fault check method and fault check device for transparent material
Inventor: YAMAMOTO TAKAHIKO
IPC: G01N21/892
Filed: 1994-08-05
Abstract: PURPOSE:To visually detect a transparent object from its surface with high precision by making check light incident from the end part flat surface of the transparent object to the transparent object and identifying faults of the surface and the internal part of the transparent object as brighter one or darker one than the peripheral part due to differences in a refraction ratio and a reflection ratio from those of the defective periphery. CONSTITUTION:The lower side of an object 101 to be checked is pinched by means of a guide part 104, the object 101 to be checked is supported and fixed by means of a support part 106, the check light from a light source part 102 is made incident from the end part flat surface 101A of the object 101 to be checked. The direction of check light made incident by means of a parallel holding part 105 and the surface of the object 101 to be checked are adjusted and held so that they are roughly parallel to each other. And, if a defect is founded when the incident check light passes through the inside of the object 101 being checked the light passing through the inside is refracted or reflected at a defective part and reaches the observer, and only the light from the defective part is seen bright as being observed redundant. If a defect is found at the surface part of the checked object 101, a part of the light is refracted or reflected and reaches the observer after its direction has been changed. Therefore, only light from the defective part is less observed and seen slightly dark.

IPC: C04B35/52
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To obtain a graphite material coated with pyrolyzed carbon having little impurities, dense coating layer and excellent oxidation resistance by applying pyrolyzed carbon having specified or larger crystal grain size on the surface of a graphite base material. SOLUTION: A graphite base body is subjected to CVD treatment to be coated with pyrolyzed carbon having >150Å grain size Lc(002) to obtain a graphite material coated with pyrolyzed carbon having excellent oxidation resistance. The thickness of the coating film of the pyrolyzed carbon is preferably 10 to 150μm. The graphite base body may be a normal graphite. When a carbon fiber reinforced carbon material is used, it has a smaller coefft. of thermal expansion than that of a graphite material and has an almost the same coefft. of thermal expansion as that of the pyrolyzed carbon which coats the base body. Therefore, by using the carbon fiber reinforced carbon material, problems of peeling due to difference in the coefft. of thermal expansion can be avoided.  The obtd. graphite material coated with pyrolyzed carbon is suitable for a furnace tube for an optical fiber, jig for semiconductors, graphite furnace for atomic absorption analysis, crucible for melting metals, etc.

Title: Solenoid valve
Inventor: BUERUNAA BUREEMU
IPC: H01F7/16
Filed: 1990-08-02
Abstract: PURPOSE: To obtain good magnetic force characteristic lines by forming the opposite poles of an electromagnet conically such that the conical faces of the pole have an identical conical angle. CONSTITUTION: Poles 17 of a mover 14 having an identical conical angle are formed while space apart through a work air gap 16 from a conical counter pole 15 formed on the end face at the free end of a pin 13 of a casing 10. Consequently, the plane at the work air gap 16 is widened as compared with a solenoid valve having a flat counter pole. When a coil 12 is excited, the mover 14 is pulled toward the counter pole 15 while resisting against the force of a compressive spring 19. Pressure generated from a pump 43 causes a valve 38 to abut against a valve seat 37 and a pressure medium flows through a chamber 39 into a part 44 to be coupled with a consumption unit. Consequently, good magnetic force characteristic lines can be obtained.
