Title: Semiconductor device
Inventor: HIKOSAKA YASUMI
IPC: H01L29/739
Filed: 1984-05-31
Abstract: PURPOSE:To make it possible to perform high speed operation, by using conductivity modulation of minority carriers, which are injected from the third electrode, and controlling the amount of hot injection of majority carriers by a heterojunction structure. CONSTITUTION:A contact metal 8 is formed on a p<+>-GaAs region (third electrode) 6. The (x) value of an n-AlxGa1-xAs layer 3 on the cathode side is selected to be, e.g., 0.3eV, so that a barrier, which is smaller than energy (0.36eV) between points GAMMA-L of GaAs, is formed. When the (x) value, which is smaller than energy between the point GAMMA and the point L of an upper valley, is selected, majority carriers can be injected at a hot state. The injected carriers flow to an anode electrode with a high speed being kept without transition to the upper valley. In order to control this current, minority carriers (holes) 5 are injected from a p<+> layer 6, which is the third electrode, the holes are made to flow to a heterogeneous interface and the conductivity modulation is utilized.

Abstract: PROBLEM TO BE SOLVED: To stabilize the characteristic of a product by inserting an inclusion between a primary winding wire and a secondary winding wire. SOLUTION: A multi-layer insulating electric wire 13' is normally wound to the inner side of a bobbin 11 as the primary winding wire. A PET tape 14 is wound to the outer periphery by one layer and polyurethane enamel copper wire 15' is normally wound on it as the secondary winding wire 15. Since the winding work of the enamel line is wound on the PET tape, it can considerably easily be normally wound. The PET tape is wound on the secondary winding wire 15 by three layers and they are set to be an outermost layer 17 so as to obtain a transformer. Twenty transformers are manufactured and the connection coefficients are measured. Then, the stable product without dispersion among the products at all, which has a superior characteristic in which the average value of connection coefficients is 0.978 and a standard deviation is 0.0032 is obtained.  The secondary winding wire is wound on the inclusion, normal winding becomes easy and the characteristic can be stabilized by inserting the inclusion between the multilayer insulating electric wire winding layer and the enamel line winding layer.

Title: A -sn based vibration absorbing alloy and preparation of the same
Inventor: MASUMOTO RIYOU
IPC: C22F1/04
Filed: 1979-09-05
Abstract: PURPOSE: To enhance vibration damping capability and to maintain high strength by a method wherein the Al-Sn based alloy having a specified amount of Sn is subjected to a cold working factor.  
     CONSTITUTION: The alloy is formed by melting 0.1W90wt% of Sn and the remaining Al, and if required, sub-components including specified amount of Pb, Sb, Ge, Ce, Si, Ni, Co, Fe, Nb, Zr, Ta, Ti, Ca, and B. The alloy is heated to a temperature from 150° to its melting point for 5min or more, cooled either rapidly or gradually at a rate or 1°C/s or less, and is subjected to a cold working with factor of 5% of more. After the process with the 5% or more of cold working factor, the alloy may be heated and cooled. The process provides the Al-Sn  based vibration absorbing alloy having a damping capability of 6×10 -3  or more.  Because of its high damping capability, good cold workability, and nonmagnetic  property, the alloy is suited as structure material for traffic facilities, internal combustion engines, and large machines to prevent the vibration and noise or to compact their size.

Title: Stack memory controlling system
Inventor: KUBOU KATSUMI
IPC: G06F9/40
Filed: 1982-06-30
Abstract: PURPOSE:To start easily an underflow processing routine, by setting the head address of an underflow processing program at the final or first stage of a stack memory by an instruction. CONSTITUTION:When a return instruction RTN is delivered, the head address AFAD of an underflow processing program is written to a final stage ST3 of a stack memory STM. The head address of a stack underflow processing program is delivered automatically from the memory STM in place of a return address even in case the instructions RTN more than the number of link instructions LINK are delivered, i.e., a stack counter STC is set at 0. Thus it is possible to start an underflow processing routine with no intervention of an interruption processing circuit and an interruption control circuit. Furthermore the address AFAD is written to the first stage of the memory STM even though it is decided at the link destination by a microprogram that the continuation is impossible for the original process. Thus an underflow processing program can be automatically started.

Abstract: PURPOSE:To simply output a laser output light in a direction perpendicular to a semiconductor substrate by providing an end face having a light emitting section perpendicular to the face of the substrate and inclined at approx. 45 deg. to the substrate at the face perpendicular to the guiding direction of an active layer. CONSTITUTION:A laser resonator is formed between the end face 9 of the laser resonator perpendicular to the face of a semiconductor substrate 1 and an emitting unit 12 of the surface of a cap layer 5 of the uppermost layer of an epitaxially grown layer. An inner mirror is formed of a 45 deg. undercut face 13, and the cutting angle theta of this face, i.e., an angle formed between this face and the surface perpendicular to the layer 5 is theta=35 deg. + or -x deg. (x<20). Since the refractive index of a semiconductor layer is -3.3 and that of an outer medium (normally the air) is -1.4, reflection coefficients at the end 14 of the active layer is near 1 for TE and TM waves to be totally reflected. Thus, a surface light emitting type semiconductor laser element in which an output light is output perpendicularly to the face of the substrate by the inner mirror is obtained.

Abstract: PURPOSE:To stabilize the quality of a semiconductor device by forming a light shielding metallic layer through an insulating resin layer on a control element portion in an image sensor such as a charge transfer device or the like as a monolithic architecture with a photosensor and a control element portion for controlling the photosensor. CONSTITUTION:A photosensor portion 1 and a control element portion 2 for controlling the photosensor portion 1 photosensor portion 1 are formed as an image sensor with a monolithic architecture adjacent to a semiconductor substrate 3. Then, polyimide group resin 6 such as polyimide.isoindoro.quinazorinon colored on the portion 2 is repeatedly coated thereon not to produce pinholes. Since complete ligh shielding effect may not be obtained as it is, an aluminum layer 7 is thereafter coated on the resin while coating the resin 6 on the end. Thus, the shielding effect of the portion 2 can be completed, no error occurs in the sensor, and high production yield can be stably obtained with high quality.
