Title: Alignment winding method and apparatus
Inventor: TANEDA KOUKI
IPC: H01F41/06
Filed: 1978-05-31
Abstract: PURPOSE: To accomplish the alignment winding regardless of variance in dimensions by changing the direction of wire supply at a given number of turn with the winding started after adjustment of the bobbin width through calculation of the number of turn and width per layer from the width of bobbin and the diameter of the wire.  
     CONSTITUTION: The width of the bobbin 15 is adjusted by calculating the number of turn and the width per layer enough to allow alignment winding from the width of the bobbin 15 with the width variable and the diameter of the wire 19. Then, the winding is started with the start point of the wire 19 set on a flange of the bobbin. After the winding is made around the bobbin by a given angle, the holding of the wire with a push plate is released and the wire supply position is moved freely in a given delay with respect to the winding position. When the wire 19 attains the position at which it is supplied straight along the flange 15b from the position at the right angle to the bobbin axis after the given number of turn is reached, the supply position is changed in the direction. With such an arrangement, the alignment winding is possible regardless of variance in the dimensions of the bobbin 15 and the wire 19, if any.

Title: Carrier for semiconductor wafer
Inventor: USUI KAORU
IPC: H01L21/68
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain a carrier for semiconductor wafer in which a semiconductor wafer contained in the carrier is prevented from being contaminated with foreign matters during carriage or being warped by attracting the semiconductor wafer fixedly to a support, i.e., an electrostatic chuck. SOLUTION: A carrier containing a plurality of semiconductor wafers 2 is held at the handle thereof and transferred while being mounted on a moving truck. When it is connected not with the DC power supply of the moving truck but with an independent DC power supply 4, the carrier can be used as a preservation case as it is. More specifically, an electrostatic chuck 3 provided on the carrier supports the semiconductor wafer 2 horizontally at the opposite ends on both sides and brings the gravitationally warped semiconductor wafer 2 into tight contact with the supporting face of the electrostatic chuck 3 through no gap thus lessening the warp. Furthermore, no foreign matter, e.g. abrasion powder, is generated through fixing of a movable part because the support, i.e., the electrostatic chuck 3 itself, secures the semiconductor wafer 2 which is thereby protected against contamination with foreign matters.

Abstract: PURPOSE:To give sufficient strength to the titled semiconductor device as well as to increase mass-productivity of the device by a method wherein, after an insulating film has been formed on the exposed surface of the laminated body consisting of the first conductivity type III-V compound semiconductor substrate and an N-group semiconductor substrate, the first conductivity type high density impurity layer is formed on the back of the compound semiconductor substrate by diffusing the constituent atoms located between both substrates by performing a heat treatment. CONSTITUTION:The insulating film 4 such as an SiO2 film, an Si3N4 film and the like is formed on the exposed surface of the laminated body 3 consisting of the N-type GaAs substrate 2 laminated on a silicon substrate 1. A high density impurity layer (a buried collector region) 5 is formed by diffusing Si from the Si substrate 1 to the GaAs substrate 2 by performing a heat treatment at 1,000 deg.C for 30min in an Ar/As atmosphere, and at the same time, Ga and As are diffused to the Si substrate from the GaAs substrate 2. Moreover, utilizing said region 5, a bipolar transistor is formed on the GaAs substrate 2. Accordingly, as the back of the GaAs substrate 2 is supported by the mechanically strong Si substrate 1, sufficient strength can be given to the substrate 2. Also, as the thickness of the heat-treated laminated body 3 can be controlled by performing a polishing and an etching from the surface side of the GaAs substrate 2, the productivity of the semiconductor device can be increased substantially.

Title: Method for inhibiting overcurrent of power supply
Inventor: SANUKI NAGAKADO
IPC: G05F1/10
Filed: 1981-04-30
Abstract: PURPOSE:To obtain a drooping characteristic which does not cause unstable operations, suh as hunting, etc., when an overcurrent is generated, by giving a hysteresis characteristic to a control signal produced based on a peak-hold detected value of an instantaneous value at a half cycle of the main current flowing through a semiconductor device for controlling electric power. CONSTITUTION:The main current of a semiconductor device for controlling electric power Tr is detected by a current detector Dc. The output of the detector Dc outputs an inhibit signal CL to a controlling circuit Av at an instantaneous value of a half cycle of the main current in an overcurrent inhibiting circuit. The circuit Av controls the device Tr with the signal CL, and outputs a constant voltage of a power source E to terminals T1 and T2 through a transformer  T and rectifier elements D1, D2, L, and C. When the peak-hold detected value is higher than a reference level, the signal CL lowers the reference level to a lower level, and, when the peak-hold value exceeds the lower level, inhibits the delivery of a drive signal Ds from the circuit Av. In this way, a power unit having a drooping characteristic which does not cause any hunting can be obtained by utilizing the hysteresis characteristic between the two levels.
