Title: Ceramic package type semiconductor device
Inventor: SUDOU TAKESHI
IPC: H01L21/52
Filed: 1978-10-16
Abstract: PURPOSE: To prevent inclinations in pellets and prevent the occurrence of defective products, by making the thickness of a glass material less than the thickness of a pellet when a semiconductor pellet is bonded thru glass in a cavity on a ceramic base.  
     CONSTITUTION: Molten cavity glass 2 is supplied into a cavity provided on ceramic base 1, and here semiconductor pellet is mounted and fixed by cooling. At this time, the thickness of glass 2 is set below the thickness of pellet 3. Subsequently, the terminal of the electrode provided on pellet 3 is connected to lead frame 4, which is prouided on glass layer 5 for sealing the surrounding wall of base 1. Sealing is done by placing a cap. By this, it is possible to operate bonding of pellet 3 with the back surface of base 1 as reference, so that positioning is simplified. Further, since there is no inclanation in pellet 3, no defective bonding occurs.

IPC: F01D5/06
Filed: 1984-06-21
Abstract: PURPOSE:To prevent the condensation of steam flowing into the keyway parts of wheels so as prevent effectively stress corrosion cracking, by communicating the clearances between wheels on the upstream side with an exhaust chamber on the downstream side by means of communication passages provided on a rotor. CONSTITUTION:Plural number of wheels 12 each of which is provided with blades 11 on its periphery are shrink-fitted on a rotor 13 via fit drive keys 14 respectively. In this case, a clearance is provided between bore parts 15 of neighboring wheels 12, and outside space of each bore part 15 is communicated with an exhaust chamber 17 at the downstream of low-pressure stage wheel through the said clearance and a communication passage 16 formed in the rotor 13.

Title: Higher harmonic generator
Inventor: SATO HIROMASA
IPC: G02F1/37
Filed: 1995-05-25
Abstract: PURPOSE: To avert the nonstabilization of the oscillation frequency of an LD and the degradation in the coupling efficiency to a resonator occurring in an increase in an oscillation spectral line width by shifting a basic wave from the resonance axis of the resonator and making the basic wave incident on the resonator so as to be in alignment to the axis within the permissible resonance width parallel with the resonance axis. CONSTITUTION: The semiconductor laser (LD) 102 emits the basic wave 105. The basic wave 105 is condensed by a coupling optical system 103, is matched with a resonance mode and is made incident on the resonator 104. This standing wave linear resonator 104 is composed of a resonance mirror 106 and a nonlinear optical crystal 108. In such a case, the optical axis 110 of the incident basic wave is deviated from the resonance axis 111 and is in parallel with the resonance axis 111. The distance from the resonance axis 111 is in alignment to the prescribed axis.  Part of the basic wave 105 is not made incident on the resonator 104 in this arrangement and since the optical axis 110 of the incident basic wave and the optical axis of the directly reflected light 112 reflected at the incident face have a specified angle, the basic wave is not condensed again at the light emitting layer of the LD 102. Then, the oscillation frequency of the LD 102 is stable and the increase in the oscillation spectral line width does not arise.

Filed: 1990-05-18
Abstract: PURPOSE:To make it possible to eliminate an oversight of an extraneous substance by separating and detecting the extraneous substance from the background by a threshold curve determined on a two-dimensional plane which is formed of detection signal values obtained by first and second detecting means. CONSTITUTION:An extraneous substance emphatical detection output VL obtained from a photoelectric conversion element 6L which detects an extraneous substance on a wafer 1 with emphasis and a pattern emphatical detection output VH obtained from a photoelectric conversion element 6H which detects a pattern (background) on the wafer 1 with emphasis are converted into digital values by A/D converters 12. Then, a free curve threshold f(VL) determined primarily for the value of the extraneous substance emphatical detection output VL is outputted by a threshold memory 13, with the value of the VL used as an address, and the pattern emphatical detection output VH and the threshold f(VL) are compared with each other by a comparator circuit 14. In this way, the extraneous substance is recognized as existing when the pattern emphatical detection output VH is smaller than the threshold f(VL). According to this constitution, an oversight of the extraneous substance in proximity to a pattern existing area is prevented.

Title: Compensation of residual voltage of hall element
Inventor: SATOU TADASHI
IPC: H01L43/06
Filed: 1981-08-14
Abstract: PURPOSE:To simplify process for compensation and to enhance accuracy of compensation by a method wherein an offset-voltage compensating circuit is provided on th input side of an operational amplifier. Outputted residual voltage of a Hall element generated when magnetic field strength impressed to the Hall element is zero, can be eliminated by adjustment of offset voltage. CONSTITUTION:The index number ''4'' in this figure is an operational amplifier through which output of a Hall element 1 can be taken out. The index number ''5'' represents the offset-voltage compensating circuit which is connected on the input side of the operational amplifier 4. A constant-current power supply 2 supplies electric current to the Hall element 1 in this circuit to output voltage proportional to impressed magnetic field strength. Even though impressed magnetic field strength is zero, output by residual voltage appears, but negative voltage -V'r can be generated against the residual voltage V'r by adjustment of the offset-voltage compensating circuit 5 which is connected to the operational amplifier 4 so that output voltage Vo of the operational amplifier 4 can be zeroed when impressed magnetic field strength becomes zero. Then, the intrinsic offset voltage of the operational amplifier 4 can be compensated together.

IPC: B29C70/16
Filed: 1993-05-28
Abstract: PURPOSE:To prevent the occurrence of a cracking even in a thick-walled laminate by adding a fine magnetic material to a thermosetting resin impregnated continuous fiber used in a filament winding method and winding this continuous fiber having the magnetic material added thereto around the core mold and curing the wound fiber layer under heating using a high frequency induction heating device.

Abstract: PURPOSE:To reduce the contact pressure produced when a liner and a disk are revolved with a contact secured between them by using an unwoven fabric consisting substantially of nylon fibers to the disk contact surface. CONSTITUTION:A parallel card web is produced with a single fiber degree of 2 deniers, the fiber length of 51mm, and the 10g/m<2> weave of nylon-6 fiber 100wt%.

IPC: B29K105/12
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To provide a laminate which shows no undermined mechanism strength even when it is foamed at a high magnification and also outstanding molding properties with sufficient lamination strength by laminating and forming a thermoplastic resin platelike foam obtained by dispersing a fibrillar liquid crystal resin in a thermoplastic resin having a lower fusion temperature than the transition point of the liquid crystal resin, and a skin. SOLUTION: A liquid crystal resin and a thermoplastic resin having a lower fusion temperature than the transition point of the liquid crystal resin are melted and mixed above the transition point of the liquid crystal resin to obtain a fibrillar dispersion mixture. Further, this mixture is molded into a sheetlike form below the decomposition temperature of a pyrolytic foaming agent showing a higher fusion temperature than that of the thermoplastic resin and a lower decomposition temperature than the transition point of the liquid crystal resin and thus a foamable resin sheet is obtained. In addition, the foamable resin sheet is made to foam above the decomposition temperature of the pyrolytic foaming agent and below the transition point temperature of the liquid crystal resin. Thus a thermoplastic resin platelike foam is obtained.  Next, the thermoplastic resin platelike foam and a skin agent are laminated above the fusion temperature of the thermoplastic resin and below the transition point temperature of the liquid crystal resin.
