Title: Link device
Inventor: FUJITA NOBORU
IPC: F16H21/00
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To perform smooth movement of an arm, to decrease the number of parts, and to simplify an assembly work. SOLUTION: A link device 30 is formed such that a shaft part 32 formed of a sheet 31 is inserted in the mounting hole 34 of an arm 33 and to form a rotary shaft and in a way that a caulked part 35 is formed in a slip-off preventive part, the arm 33 is rotatably mounted. The caulked part 35 is formed by bending a cylindrical part having a diameter smaller than that of the shaft part 32 and outer peripherally protruded in a flange-form state from the outer peripheral surface of the shaft part 32. Further, the height of the shaft part 32 is slightly higher than the thickness of the arm 33 and further, a diameter is set to a value slightly lower than that of the mounting hole 34. Thus, the caulked part 35 does not contact with the hole edge part of the arm 33 and the arm 33 is smoothly rotatable. Further, since a difference part, such as a caulking pin, is not used, the number of parts is reduced and an assembly work is simplified.

Title: Control valve for heavy equipment having reproducing function
Inventor: HIYUN JIYON CHIYO
IPC: F15B13/02
Filed: 1995-06-30
Abstract: PURPOSE: To provide a precise regeneration function by moving a regeneration spool based on the supply oil quantity of a pump, increasing the quantity of oil to a tank port during oil discharging from an actuator port and reducing the quantity of oil to a regeneration port. CONSTITUTION: When a main spool 2 is moved in an A direction, a pimp port P and a hydraulic chamber 5 are communicated with each other by an internal passage 6, and a regeneration spool 3 is pushed in a B direction by the supply oil quantity of a pump. At this time, if the quantity of supply oil is small and the set pressure of a pressure setting spring 4 is not maintained, the regeneration spool 3 is not moved in the B direction, after the oil quantity of a return side actuator port is discharged through a passage 12, a part of the oil quantity flows through a passage 22 to a regeneration port, and the residual oil quantity is returned through passage 23 and 24 to a tank port.  When the quantity of supply oil is increased, the regeneration spool 3 is moved in the B direction, the opening area of a passage 25 is increased/reduced in proportion to the quantity of supply oil, and when the quantity of supply oil is increased, the quantity of oil returning to the tank port is increased, and the quantity of regeneration oil is reduced in relative relation. Thus, the quantity of regeneration oil is properly increased/reduced.

Filed: 1988-07-29
Abstract: PURPOSE: To produce a Pd alloy acting as a catalyst to oxidize the hydrogen in an atmosphere contg. hydrogen and oxygen by compounding Pd, Ni and Cu at specific ratios.  
     CONSTITUTION: The Ni-contg. Pd alloy metal consisting of at least 80wt.% Pd, max. 19.9wt.% Ni and max. 10wt.% Cu is prepd. This Pd alloy acts as the catalyst to rapidly oxidize and remove the hydrogen in the atmosphere contg. the hydrogen and the oxygen at a surface temp. of about 100°C and is, therefore, useful for removing the hydrogen from the atmosphere of the safety vessel of a nuclear reactor. Since the Pd alloy generates heat at the time of catalyst oxidation of the hydrogen, the alloy is supported on one or both surfaces of a supporting plate having reaction heat absorptivity. Al or Al alloy is adequately used for this supporting plate.

Title: Shading correction method
Inventor: KONDO HIDEYUKI
IPC: H04N5/16
Filed: 1989-07-20
Abstract: PURPOSE:To attain accurate shading correction even against a complicated shading characteristic by storing an actual shading characteristic including an element such as dispersion in a lighting system and an image sensor to a correction data. CONSTITUTION:A picture of an object 1 is formed on a photodetector face of an image sensor 3 through an image forming lens 2, a signal outputted from the image sensor 3 for each picture element is amplified by an amplifier 4 and converted into a digital signal by an A/D converter 6 for the output. Since a correction data corresponding to all densities as to all picture elements of the image sensor 3 is stored based on the shading characteristic obtained through the input of a picture having a uniform brightness distribution, the actual shading characteristic including factors such as the dispersion in the lighting system and the image sensor 3 is stored in the correction data. The density data of the input picture is corrected according to the above shading characteristic. Thus, accurate shading correction is applied even against a complicated form of the shading characteristic.

Title: Coil type contact piece and connector using it
Inventor: TAKAHASHI TORU
IPC: H01R13/11
Filed: 1993-06-30
Abstract: PURPOSE:To construct a connector in a small size by arranging so that the axes of pitch loops constituting an electroconductive coil spring are oriented in inclination to the long axis of the coil spring. CONSTITUTION:An electroconductive coil spring 1A is made of beryllium copper, titanium copper alloy, etc., and the axes X of its pitch loops 2 are inclined to the long axis Z of a coil spring so that parallel orientation to one another is obtained. The pitch loops 2 are formed in tight contact so that parts thereof are short-circuiting to one another. The two ends P1, P2 of the coil spring 1A constitute a coil type contact piece 1 owing. for example, to the arrangement such that they lie at the pressure receiving points for the pattern of a wiring board and the terminals of a leadless type IC package. Because the pitch loops 2 are short-circuiting to one another, the inductance of the contact piece itself 1 is extremely small.
