Title: Manufacture of semiconductor device
Inventor: OKAMURA SHIGERU
IPC: H01L29/812
Filed: 1983-06-09
Abstract: PURPOSE:To reduce the contacting resistance of a source and a drain by providing a gate electrode formed on the second semiconductor layer having an electron affinity smaller than the first semiconductor layer formed on the first semiconductor layer having an impurity implanted region, and source and drain electrodes having an alloy region reaching to the impurity implanted region. CONSTITUTION:A GaAs layer 2 of nondoped GaAs is grown on a semi-insulating GaAs substrate 1, and a mask film 3 is formed thereon. Then, holes 4, 5 are formed, an N<+> type source region 6 and drain region 7 are formed by doping to the layer 2 through the holes 4, 5, and the film 3 is removed with suitable etchant. Then, a protective film 8 is formed on the layer 2, heat treated, and removed. After the film 8 is removed, the surface of the layer 2 is etched to remove the surface modified layer. Then, an Si-doped N type AlGaAs layer 9 is epitaxially grown on the layer 2. Then, gold germanium is deposited in vacuum to be selectively adhered onto the layer 9, thereby forming a source electrode 10 and a drain electrode 11.

Title: Working vehicle
Inventor: ICHINOSE MIKIO
IPC: B60K28/14
Filed: 1986-05-01
Abstract: PURPOSE:To allow the self-travel transfer safely in a narrow area by automatically stopping the travel when the change of the longitudinal tilt angle of a vehicle body within a predetermined time is a preset value or more in a working vehicle such as a combine. CONSTITUTION:The presence of the lateral displacement of a machine against grain straws to be reaped and the displacement direction are detected by a displacement detecting mechanism 7 and entered into a control means 19. On the other hand, the longitudinal tilt angle of the machine is detected by a sensor 12, and the tilt angle change is determined by a detecting means 18 and entered into the control means 19. The control means 19 judges whether the tilt angle change is a preset value or more, and if it judges that there is a change, it outputs signals to a stop unit drive circuit 15, a clutch operating circuit 11 and a buzzer drive circuit 17 for the engine stop, buzzer warning, and travel stop. According to this constitution, self-travel transfer is allowed safely in a narrow area.

Title: Telephone device
Inventor: IWAYA HIDEMITSU
IPC: H04M19/00
Filed: 1982-06-14
Abstract: PURPOSE:To detect an overcurrent generated at the time of short highly accurately and to make unnecessary to replace a fused fuse by providing the titled device with a constant voltage holding circuit limiting circuit to limit current at the detection of potential difference generated by the short-circuit of a line or the like. CONSTITUTION:If short-circuit is generated between P1 and P2 of a line 9, large potential difference is generated between P5 and P6 by short-circuitted currents because of a choke transformer T has some DC resistance. Since a transistor(TR) 1 is turned on by said potential difference, a thyristor S in the constant voltage holding/current limiting circuit 11 is turned on. Consequently, the emitter potential of a TR 2 is turned to about 0V, short-circuitted current is reduced and the temperature rise of the choke transformer T is suppressed and protected. If the shor-tcircuit is removed by turning off the short-circuitted current, the line 9 is normally restored and it is unncessary to replace a fused fuse.

Title: Burner device
Inventor: YAAKOBU KERAA
IPC: F23D14/02
Filed: 1990-04-19
Abstract: PURPOSE: To increase the life of a burner device and lower the generation of failures without producing an ignition outside a combustion chamber, by providing an extended part formed in a nose shaped part in a swirl vane in an opposite side to the combustion chamber, and opening a nozzle to the area of the nose shaped part. CONSTITUTION: When fuel is supplied from a nozzle 9, the fuel is concentratedly mixed with air flowing in a main supply passage 2. An air flow is guided by a nose shaped part 5a protruding in the direction opposite to the flowing direction of air. In the front edge part of the nose shaped part 5a, a fuel-air mixture cannot be produced and ignition cannot be achieved. In an area between swirl vanes 5, a cross-sectional area is reduced due to the swirl vanes, so that the air flow is additionally accelerated. Therefore, a stable combustion cannot be attained even upon generation of ignition. The mixture of fuel and air in the areas of the swirl vanes 5 completely ensures a good combustion in a combustion chamber 1. Since a premixing chamber is removed, the whole length of a burner device is decreased so that a comparatively compact structure can be achieved.

Title: Production of magnetic head core
Inventor: KAWAKAMI YOSHIO
IPC: G11B5/147
Filed: 1982-06-16
Abstract: PURPOSE:To suppress the deterioration of recording/reproducing characteristics in a high frequency region, by laminating core thin plates which are blanked from the side opposite to the insulating film forming surface of a magnetic thin plate. CONSTITUTION:An insulated film is formed on a single side of a magnetic thin plate before core thin plates 1 are press-cut out of a magnetic thin plate by using an electrophoresis process, etc. to stick aluminum oxide powder and cellulose, for example, in 3-4mum thickness. Then the magnetic thin plate containing the insulated coat, i.e., an insulated layer 2 is press-cut from the side opposite to the surface where the layer 2 is formed. Thus a U-shaped core thin plate 1 is obtained. This plate 1 is supplied with magnetic annealing in an hydrogen gas of about 1,100 deg.C, and then epoxy resin, etc. is coated on the plate 1. A prescribed number of plates 1 are laminated to form a core laminated product 5. For the lamination 5, the forming surfaces of layers 2 are set in a single direction. Thus the insulation is secured between the plates 1 and therefore reduces the impedance variation in a high frequency region.
