Title: Ignition distributor for internal combustion engine
Inventor: ASAKURA HIDEO
IPC: F02P7/02
Filed: 1988-06-29
Abstract: PURPOSE:To decrease a high frequency noise, generated following ignition, by forming a contact piece, electrically connected to a center electrode of a distributing part, by a resistance material. CONSTITUTION:High voltage, generated in an ignition coil 3, is discharged from a center electrode 14 of a distributor cap 16 to a discharge gap, formed when an electrode 13a of a distributor rotor 13 is opposed facing to an outer electrode 15 of the distributor cap 16, being distributed to each spark plug 2.

Title: Filter of supplied hot water for bathtub
Inventor: OHARA SUMIO
IPC: F24H9/00
Filed: 1986-07-10
Abstract: PURPOSE:To be able to supply hot water into a bathtub in cubic and planar stream by installing an effluent hole placed at the upper part of an upward water passage connected to the discharge hole of a circulating pump, removable closing means at the jet hole in front of the discharge hole, a filter installed at the suction passage for bathtub water, and branch chambers connected respectively to the upward water passage, the jet hole, and the suction passage for bathtub water. CONSTITUTION:When a circulating pump 13 is operated, bathtub water 12 is discharged into a branch chamber 25 and the water flows only in the direction of an upward water passage 19 and flows down into a bathtub 11. When a jet hole 17 is brought in an open state by removing a closing means 18 and also the pump 13 is operated, the water 12 forms the stream as indicated by the arrow and at the same time is returned back forcibly to the tub 11 and a negative pressure is generated to suck up the water only from a suction passage 27 for the bathtub water. Therefore, the water passes through a filter 28 and meets the water 12 discharged from a discharge hole 16 and the confluence spouts in a jet stream from the hole 17 into the tub 11.

Title: Picture encoding calculation system
Inventor: HATTORI SHINICHI
IPC: H04N19/51
Filed: 1990-06-20
Abstract: PURPOSE:To attain efficient encoding by comparing a moving vector and a prediction error evaluation with a prescribed threshold level and selecting out a predicted error block predicted to be an invalid block in advance. CONSTITUTION:A picture encoding device consists of a pre-processing section 1, a moving compensation in-frame/inter-frame prediction section 2 and an encoding section 3. Then a moving vector and a prediction error evaluation value obtained by the moving compensation in-frame/inter-frame prediction are used to select out a prediction error block predicted in advance to be an invalid block, which is eliminated from an object of conditional picture element supplement processing. Thus, an undesired arithmetic step number is saved and efficient picture encoding is implemented.

Title: Integrated semiconductor device
Inventor: OBUSE KAZUHIRO
IPC: H01L21/82
Filed: 1992-06-22
Abstract: PURPOSE:To make it possible to transmit a correct signal and run at high speed without operational failures. CONSTITUTION:In terms of an electrode section 1 of a transistor which performs switching operations, a metal thin film wiring 2 which transmits an output signal of the transistor and a change-direction section 3 for the metal thin film wiring 2, the configuration of circular arc is adopted to provide a radius which exceeds the width of the metal thin film wiring 2. Repetition of such patterns constitutes this integrated semiconductor device. Since the change- direction section of the metal thin film wiring 2 is circular arc in shape, the intrinsic impedance of the wiring is mild in change while the generation of reflected waves from the change-direction section 3 is minimized. As a result, a transmission signal can be conveyed with accuracy without deformation from its original waveform. This construction makes it possible to suppress the reflected waves from the change-direction section 3 and transmit an accurate signal and provide an integrated semiconductor device capable of running at high speed without operational failures.

Title: Two cycle combustion
Inventor: TAKAMATSU KIYOSHI
IPC: F02B25/24
Filed: 1990-06-20
Abstract: PURPOSE:To form the strata of air-fuel mixture layers within a cylinder in a wide range from low load to high load by starting to open a scavenge port after the definite period of time for blow-down has elapsed, so that scavenging is started, opening an inlet valve after the definite period of time for scavenging has elapsed, and thereby closing an exhaust valve. CONSTITUTION:When an engine is in operation at high load side, only air passing through an intake passage 14 in an air system furnished with no fuel feed means 12 is fed into a cylinder 4, so that it pushed exhaust gas within the cylinder 4 out through an exhaust valve 3. In the second place, after the definite period of time for scavenging has elapsed, an inlet valve 2 is opened, air-fuel mixture is started to be led in. And before and after the induction of air, an exhaust valve 3 is closed. Since the intake passage B in an air-fuel mixture system is gradually lowered in pressure as the inlet valve 2 is opened, the difference in pressure from the side of a scavenge port 5 is made small. This thereby causes the amount of air passing through an intake passage 14 in the air system to be gradually throttled by a lead valve 15.

Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To provide a surface light emitting semiconductor element, which emits a light of almost uniform light intensity and outputs a high output, and to provide its manufacturing method. SOLUTION: An n-(Alx Ga1-x )z In1-z P lower clad layer 2, a p-(Aly Ga1-y )z In1-z P light emitting layer 3, a p-(Alz Ga1-x )z In1-z P upper clad layer 4 and a p-GaAs cap layer 5 (O<=y<x<=1, O<=z<=1) are epitaxially grown successively on an n-GaAs substrate 1. Then, p-conductive type impurities are doped on the upper clad layer 4 located below a light taking-out window 10. After a semiconductor layer has been grown as far as to the cap layer 5, the upper clad layer 4 can be doped heavily by doping it. A current is sufficiently diffused to the upper clad layer 4, and as a result, the intensity of light emitted to the outside from a light take-out region can be made almost uniform. Also, as impurity density is high, current density is increased, and a high output light can be emitted.

The raw material powder packed layer is thereby compacted and integrated together with the metallic powder layer 2. The metallic powder layer 2 having a smaller difference of the impact impedance with respect to the raw material powder is used. The amorphous metallic molding having no defects and deteriorated parts in the inside is obtd. by the above-mentioned method.
