Abstract: PURPOSE:To enhance the recombination efficiency of electrons and holes and to obtain a light emitting diode characterized by high luminance, by epitaxially growing a GaAlP layer on a GaAsP/GaP wafer, forming a P-N junction, thereby providing an electron confining effect. CONSTITUTION:A P-type GaAlP layer 1 is epitaxially grown on an operating layer 13 on a GaAsP/GaP wafer 10, and a P-N junction part is formed. At this time, relationship between gallium Ga and aluminum Al is made to be Ga(1-x) and Al(x). Adjustment is made so that mismatching between an operating layer 13 and lattice constant is made minimum. A GaAlP layer, whose energy gab (a) is larger than that of the operating layer 13 of GaAsP, is epitaxially grown. The confining effect of electrons is enhanced. The probability of the recombination of the electrons and holes is enhanced. The luminance of the light emitting diode is improved.

IPC: C10C3/10
Filed: 1985-07-24
Abstract: PURPOSE:To obtain in high yield optically isomeric spherules having controlled particle diameters, by heat-treating remixed pitch or pitch obtained by fractionating a specific component and selecting a temperature to cool a heat-treated material while stirring. CONSTITUTION:Pitch containing no free carbon obtained by heat treatment (and hydrogenation treatment) is used as a raw material and separated into a solvent-soluble component and a solvent-insoluble component by the use of an aromatic solvent. The two components are remixed by changing its ratio and heat-treated again at the above-mentioned heat treatment temperature - a temperature 200 deg.C lower than it while stirring to form optically isomeric spherules. Then, a temperature to cool the repeatedly heat-treated material while stirring is selected to control the particle diameters of formed spherules.

Title: In-cylinder pressure measuring apparatus for diesel engine
Inventor: MARUYAMA YASUO
IPC: G01L9/00
Filed: 1993-06-07
Abstract: PURPOSE:To accurately measure a pressure by providing a pressure receiving part and a pressure sensing part at a closed end and a sidewall of a cylinder, providing a vibrating film outside the sensing part, exciting it with a predetermined frequency, and detecting a change of the vibrating frequency of the film upon change in a length in a reference distance direction. CONSTITUTION:An inner wall surface 1 of a closed end 3 of a cylinder 5 becomes a pressure receiving part 2, and a pressure sensing part 4 having sidewall 18 continued perpendicularly to the part 2 is elongated or contracted according to a magnitude of a pressure received by the part 2. A reference distance L is from one end 4a to the other end 4b of the part 4. A vibrating film 7 is extended on the side of an outer wall surface 6, and always excited with a predetermined vibrating frequency by a magnet coil 8. When the part 2 receives a pressure, the part 4 is elongated or contracted in the direction of distance L, and the film 7 is also thereby elongated or contracted. Thus, the vibration of the film 7 is varied from the vibrating frequency at the distance L. This varied frequency is picked up, and a pressure is calculated by an arithmetic unit.

Title: Control of solenoid drive frequency
Inventor: HAYASHIDA MASAHIRO
IPC: F02B75/02
Filed: 1988-06-30
Abstract: PURPOSE:To control solenoid drive frequency with no roughing of air fuel ratio (A/F) through entire range of engine drive, by making a solenoid drive frequency H proportional to the engine speed R, so as not to make a R/30H value an integral number. CONSTITUTION:In order to control a solenoid drive frequency, it is judged if the detected engine speed R is in augmentation or not, and the judgement is to be made in consideration of engine speed, throttle opening, temperature of cooling water. If the speed is not in augmentation, the frequency is controlled by a predetermined frequency, while in augmentation, n=R/30H is determined. Then, if the n is an integer or not is judged, and if it is other than an integer, the frequency is controlled by a predetermined frequency Hs, and if it is an integer, the frequency is controlled by a predetermined frequency KHs multiplied by a proportional constant. The process is repeated at every predetermined period. The mentioned method of control is for 4-cycle engine, and if it is to be applied to a 2-cycle engine, synchronizing engine speed is determined as n=R/60H.

Title: Method of reducing production of nox in furnace by blowing in steam
Inventor: KAKETA KENJI
IPC: F23C99/00
Filed: 1983-09-05
Abstract: PURPOSE:To reduce the damage of a furnace wall, a furnace floor, etc. and to reduce production of NOX through prevention of the occurrence of incomplete combustion, by a method wherein steam is blown into a secondary air so that O2 concentration at an exhaust gas outlet is maintained within a given range. CONSTITUTION:An amount of a secondary air, supplied through a secondary air feed pipe 14 to the upper part of a combustion chamber 1, is controlled by a damper 15 so that O2 concentration (dry base) in exhaust gas at the outlet of a combustion chamber 1 is detected to maintain the resultant value at a specified value within a range of 4-10%. Namely, a flow rate control valve 18, located halfway along a steam feed pipe 17, is automatically regulated so that, through mixture of steam into a secondary air, O2 concentration is adjustable into a specified value B (%) within a range of 10-21%, and moisture content concentration C (%) in a secondary air after mixture of steam is brought to C=100B/ 21-100. This causes control of combustion of unburnt gas, decreases an amount of NOX produced, and simultaneously, further reduces production of NOX by a self-denitrating effect produced by water-gasifying reaction of steam to a carbon content in flame.

Abstract: PROBLEM TO BE SOLVED: To detect the voltage of a power source having a fairly high voltage while preventing enlargement of a circuit, increase of cost, increase of heating, reduction of a detection accuracy and so on. SOLUTION: The voltage of a power source 17 is divided by first and second potential resistors R1, R2 connected to the power source 17 and a potential difference V1 appearing between both ends of the second resistor R2 is converted to a primary current I1 corresponding to the potential difference V1 by an FA converter 33 to allow to flow the primary current I1 in a primary coil 3 and resistor 7.

Title: Manufacture of copper foil for printed circuit
Inventor: HINO EIJI
IPC: C25D11/38
Filed: 1979-12-19
Abstract: PURPOSE: To manufacture copper foil for printed circuit having improved peeling strength and rust preventive property, by forming a specific quantity of chromium oxide coating on the rough surface of copper foil by chromate process.  
     CONSTITUTION: Chromium oxide coating in quantity 60W90μg/dm 2  in terms of chromium is formed on the rough surface side of the copper foil to be bonded on a substrate. When the coated quantity is ≤60μg/dm 2 , formed coating is insufficient to the desired level of rust preventive power and peeling strength, and when the coated quantity is ≥90μg/dm 2 , rust preventive power increases, however over- etching is liable to be caused. When the coated quantity is in said range, the peeling strength increases with the increase in the thickness. Hence copper foil for printed circuit improved in peeling strength and rust preventive property is manufactured by a simple chromate process.
