Title: Exhaust emission control device of engine
Inventor: MATSUDA TAKASHI
IPC: F02F1/24
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To reduce deterioration of a reed valve due to heat by providing a thermal insulation means in a downstream chamber of a reed valve chest, and guiding exhaust reverse-flowing from an exhaust port to the downstream chamber of the reed valve chest through the thermal insulation means to the reed valve in the device where secondary air is introduced through the reed valve into the exhaust port. SOLUTION: When an engine is operated, exhaust pulse pressure generated in an exhaust port is applied to a pair of reed valves R through a secondary air distribution passage 24 and a reed valve chest C to open the valves. Thus, clean air is introduced from an intake system through a secondary air introduction passage 21, a valve port 28 of the reed valve R, and the secondary air distribution passage 24 into an exhaust port to be mixed in the exhaust, thereby oxidizing and purifying HC, CO and so on in the exhaust. At this time, an air permeable thermal insulation plate 34 is disposed in the downstream chamber Cd of the reed valve chest C. Thus, when heated exhaust is passed through the thermal insulation plate 34, it is cooled, so that the temperature of the exhaust reaching the reed valve R can be lowered effectively to restrain thermal deterioration of the reed valve R.

Title: Crystallization of semiconductor laser element
Inventor: ITOU MICHIHARU
IPC: H01L21/363
Filed: 1979-10-31
Abstract: PURPOSE:To make reverse conductive a PbS1-XSeX crystal of a single conductive type by a method wherein the atoms or molecules of a compound giving reverse conductiveness to the crystal are diffused in it while it is being grown. CONSTITUTION:N type PbS1-XSeX 1 and SSe 22 are contained in chambers 21, 23, respectively, and an ampule 24 is vacuum sealed. The chambers are individually heated, keeping the temperatures in the position F where the crystal 1 is located at 800 deg.C and the end portions D and E at 805 deg.C, ane leaving them unchanged for 96hr. A connecting pipe 27 is kept at the normal temperature to prevent vapor from moving. The supersaturated evaporating gas of the crystal 1 is allowed to adhere to the surface of a polychrystalline particle 1A at the point F of the lowest temperature, and the gas is thereby solidified to become a crystalline nucleus, which grows in an axial direction (100). If the temperature in the chamber 23 is increased to 200 deg.C and kept for 40min after the N type crystal 28 has grown to the specified size, S, Se, which is higher than Pb, enters into the chamber 21, while the crystal to be forme becomes A P type one. The carrier density of the P type crystal formed in this way can be readily controlled by the temperature of the chamber containing S, Se, thus making it possible to obtain a crsytal of good quality with undisturbed atomic configuration.

IPC: H01L39/06
Filed: 1987-06-08
Abstract: PURPOSE:To increase the speed of signal transmission up to the high-frequency region by using oxide ceramic superconductive material having a critical temperature more than the temperature of liquid nitrogen and that of near the normal temperature for some composition as a conductor for a hybrid IC circuit. CONSTITUTION:A conductor 1, a glass insulator 3, and an RuO2 resistor 4 are patterned from a paste-state with screen printing method. This is sintered for a few hours at 900-1100 deg.C being passed through a furnace to form a hybrid IC circuit. The conductor 1, insulator 3, and resistor 4 can be sintered in an oxidation atmosphere with one process since they are all oxide without necessity to be sintered in a separate process as in the case of a Cu conductor. Thus, an oxide ceramic superconductive material having a high-critical temperature ranging from the temperature of liquid nitrogen (77 deg.K) to near the normal temperature is used for the conductor 1 so that the speed of signal transmission is substantially increased.

Abstract: PURPOSE:To attain the functions of both the address qualification and the qualification jump in an instruction cycle with addition of a simple circuit, by using a memory storing the arithmetic data also in common with a qualifying register. CONSTITUTION:The indication of address qualification is detected by a qualifying decoder 13 for the instruction read out of an ROM2 during the fetching cycle of the instruction.

The contents of the access are latched to a latch 14, and a qualified selector 4' is selected. Thus the content of the ROM2 is set at an instruction register 5 and executed. Then the instruction fed from the register 5 during the executing cycle of instruction is decoded by an instruction decoder 16. The decoder 13 feeds the address information to the selector 12 based on the information given from the decoder 16. The content of the memory 9 which received an access is fed to an address selector 1, and the jumping address of the ROM2 is obtained.
