Title: Test of semiconductor integrated circuit
Inventor: OKUMURA KENZO
IPC: G01R31/26
Filed: 1988-03-23
Abstract: PURPOSE:To achieve a reduction in test time, by a method wherein a bias is applied to a semiconductor integrated circuit and an output of a measuring terminal is compared with upper and lower limit values of output characteristic thereof separately to enable testing without use of a DC measuring device. CONSTITUTION:A specified measuring terminal of a semiconductor integrated circuit 20 is connected to a function tester 10 composed of a controller 11, a pattern memory 12, a comparator 13 and a judging section 14 through a contact 33 to which a specified bias current is applied. The pattern memory 12 inputs an upper or lower limit value of output characteristic at a specified measuring terminal in the semiconductor integrated circuit 20 into the comparator 13 as reference voltage by a signal of the controller 11. The comparator 13 compares an output at the measuring terminal of the semiconductor integrated circuit 20 with the value to output a reject signal to a judging section 14 in case of rejection. This enables a significant reduction in test time.

Abstract: PURPOSE:To secure the fluidity of hard solder despite the formation of a film in an extremely small thickness by forming a thin film of silver, etc. by a vapor deposition or sputtering process and joining core wafers together by means of the silver solder as well as said thin film. CONSTITUTION:Both core wafers 3 and 4 are butted so that their mirror surfaces are set as opposed to each other. A rod 71 of about 1/4 silver solder is put into the 1st groove 42, and the section area of the rod 71 is much smaller than that of the groove 42. While a silver solder rod 72 having a size aoproximate to the section area of the 2nd groove 43 is put into said groove 43. The core wafers made of a metallic magnetic material are joined together by means of a solder material. In tis case, a thin film of about 0.1-0.5mu thickness made of a precious metal (silver, gold, palladium, platinum or an alloy containing mainly one of said metals) which is not easily deteriorated under the normal working conditions is provided at the desired area of junction. As a result, the fluidity of a solder material (silver solder, etc.) is secured to assure attachment of the solder material at an area near a front gap of a metallic head.

IPC: B23K15/06
Filed: 1987-03-26
Abstract: PURPOSE:To improve the effective capacity rate in a vacuum chamber by providing moving mechanisms in two directions where the mobile direction of an electron gun crosses at right angles with the mobile direction of a machining table at the outside of the vacuum chamber and bringing the capacity in the vacuum chamber close as much as possible to the volume of a work and the volume required for its movement.

Title: Wet type multiple disk clutch
Inventor: UENO KENJI
IPC: F16D25/0638
Filed: 1992-02-20
Abstract: PURPOSE:To improve durability by fitting frictional material to first friction plates, and setting the assembling time surface roughness of the faces, brought into contact with the frictional material, of second friction plates out of at least three second friction plates to be larger than that of the second friction plate positioned at the center part. CONSTITUTION:Separator plates 2 are formed of metal plates subjected to surface hardening such as shot peening and surface roughness treatment, and the assembling time surface roughness of the faces opposed to friction plates 3 on both axial end part sides is set to the larger value than that of the one positioned at the center part. The friction plates 3 are formed by attaching frictional material to both outer peripheral faces of metal plates. With the relative rotation of the plates 2, 3, the friction face positioned at the center part wears easily, but those on both end part sides do not wear easily. The wear generated at the friction faces of the plates 2, 3 thereby progresses evenly on the whole, and the coefficient of friction between both plates 2, 3 is stabilized into the specified value to improve durability.

Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To provide an optical amplifier which can provide a stable gain, a small gain deviation between signal wavelengths and less leakage of internal oscillation light with a simple arrangement. SOLUTION: Signal light is demultiplexed by an optical wavelength demultiplexer/multiplexer 14 according to its wavelengths, demultiplexed light of the different wavelengths are gain equalized by optical attenuators 16, a demultiplexed output to which the signal light is not allocated, that is, the demultiplexed output of wavelengths outside of the wavelength band, is fed back to an amplification part which includes an optical demultiplexer 11, an exciting light source 12 and a rate-earth added optical fiber 13 for internal oscillation, thus stabling the gain. That is, a gain stabilization can be realized, a gain dependency on wavelength can be reduced, and it is prevented that the internal oscillation light externally leaks.

Title: Resin composition for binding molding sand particle
Inventor: OOKAWA HIROE
IPC: B22C1/22
Filed: 1979-06-07
Abstract: PURPOSE: To evenly harden the mold and improve yield by compounding the limited amount of unsaturated prepolymer or monomer or their mixture in unsaturated polyester and using the same as the composition for binding sand particles.  
     CONSTITUTION: Fumaric acid being an unsaturated acid and ethylene glycol and isophthalic acid being saturated acids are mixed and cause to make esterification reaction to be made into the crystalline unsaturated polyester which is solid at ordinary temperature and has virtually on tackiness. Next, the polyester resin composition comprising adding the unsaturated prepolymer copolymerizable with the unsaturated polyester or one or two or more kinds of styrene, divinylbenzene and diarylphthalene as monomers at 0W50pts.wt. based on 100pts.wt. of the unsaturated polyester is used as a binder for sand particles. The reason for limiting the addition amount is: The addition of more than the limited amount makes the coated sand extremely tacky, resulting in decreased bulk density and decreased intensity of molding.
