Title: Controller of steering force for power running gear
Inventor: MORISHITA MITSUHARU
IPC: B62D6/02
Filed: 1983-11-15
Abstract: PURPOSE:To always maintain steering force at a proper value corresponding to a vehicle speed by permitting a feedback abnormal fail-safe malfunction protective circuit not to operate even when the temperature in a proportional solenoid rises or the voltage in a power supply is lowered. CONSTITUTION:When an engine is started in the state of increasing a resistance value of a coil by the temperature rising in a proportional solenoid 6, namely, when the voltage in a power supply is continued in the state of abnormal lowering over a given time, as the reference voltage of an error amplifying circuit 702, corresponds to the state for stopping a car, a maximum current cannot be allowed to flow in spite of indicating the maximum current, and a feedback abnormal fail-safe operating circuit 712 is operated to output a voltage. However, as a point ''b'' against a point ''a'' is set not to drop under a given rate, a feedback abnormal fail-safe malfunction protective circuit 713 would not be operated. Whereby, it is possible to prevent malfunction of the feedback abnormal fail-safe operating circuit 712.

Title: Semiconductor device
Inventor: YAMAGUCHI YASUO
IPC: H01L27/12
Filed: 1987-08-27
Abstract: PURPOSE:To decrease a short channel effect and a kink effect, by setting the thickness of the channel part of a MOS type field effect transistor (MOSFET) so that all the part is transformed into a depletion region by the application of a gate voltage. CONSTITUTION:A groove part 16 is formed in a semiconductor active layer 15. A semiconductor single crystal region, i.e., a channel region 5A, is formed thinly. The thickness of the region is set at, e.g., 500-1,500Angstrom  so that all the region is transformed into a depletion region when a gate voltage is applied. The impurity concentration of this region is set at, e.g., 1-5X10<16>/cm<3>. As a result, a region in which carriers can move is restricted in a narrow region directly beneath a gate insulating film 7. The entire channel region can be controlled with the gate voltage. The end parts of a source region 3 and a drain region 4 are brought into contact with the channel region 5A at the thin semiconductor single crystal layer beneath the groove part 16. Thus, the edge part of the drain region 4 can be eliminated. Concentration of an electric field at the drain edge part can be prevented, and the yield of extra pairs of electrons and holes can be suppressed.

Title: Gallium nitride based semiconductor light-emitting element
Inventor: ITAYA KAZUHIKO
IPC: H01S5/323
Filed: 1996-08-13
Abstract: PROBLEM TO BE SOLVED: To lower the threshold value by employing InGa AIN set at a specified composition in a barrier layer of a quantum well structure. SOLUTION: A barrier layer of multiple quantum well structure has composition shown by Inx Ga1-x-y Aly N (0<x<0.5, Y<0.8x+0.05). When In composition x exceeds 0.5 in the composition InGaAlN of the barrier layer, laser oscillation cannot take place. When it is not lower than Al 10.5, resistance is increased significantly through a laser element. The relation represents the boundary between these defective growth conditions and high quality growth conditions. Even when the InGaN is added with a small quantity of Al to produce a mixed crystal, the well becomes sufficiently deep on the conduction band side, as compared with valence band side and light electrons can contribute to oscillation without casing overflow thus lowering the threshold value.

Abstract: PURPOSE:To extend the width of a V-shaped N<+> buried layer without degrading the degree of integration, and to reduce collector resistance without influencing effects on others by forming the buried layer near the surface of a P type Si substrate, the surface thereof is (100). CONSTITUTION:A V-shaped groove 12 is formed to the (100) face of the P type Si substrate 1 through anisotropic etching, and Sb is introduced and the N<+> layer 13 is formed.

The N layer 14 is isolated by a P<+> layer, a P base 16 is formed just above the buried layer 13, and an N emitter 17 is manufactured. Since the buried layer 13 takes V shape, it is formed widely in the same area as conventional devices, and the resistance value of the N collector layer 14 can be lowered. An N<+> collector extracting layer 18 is formed, and each electrode is attached. Accordingly, a buried region can be extended without expanding the occupied area of a transistor, etc., and collector resistance can be reduced.

Abstract: PURPOSE:To obtain a high-quality picture by fixing the cylinder fixing portion of a tab to the inside face of a support cylinder to make the external dia. of the support cylinder small for reducing input capacity. CONSTITUTION:The external dia. of the cylinder fixing portion 14c of a tab 14 is shaped to be larger than the internal dia. of a support cylinder 15. When a cathode sleeve 3 to which the tab 14 is welded and fixed is inserted into the support cylinder 15, the cylinder fixing portion 14c is adhered to the inside face of the support cylinder 15 by spring force. So, a laser beam is used to weld the support cylinder 15 externally. As the support cylinder 15 has not a flange and the tab 14 is fixed to the inside face of the support cylinder 15, the external dia. of the support cylinder 15 can be made small. In this way, the external dia. of the support cylinder 15 can be made small, and it, therefore, reduces the input capacity of a cathode and obtain a high-quality picture.
