Title: Intake valve for internal combustion engine
Inventor: TSUZUKI TATSUYA
IPC: F01L3/02
Filed: 1993-08-27
Abstract: PURPOSE:To ensure good abrasion resistance and heat transmitting rate without using an iron material by footing the material of a shaft part and an umbrella part of a reinforced Al base MMC(metal matrix composite) by adding ceramic particle whose Al system or Mg system alloy is formed as a matrix, a whiskers, and a fiber respectively. CONSTITUTION:In the axial part and the umbrella part excepting a valve face, for example, SiCw fiber reinforced Al base MMC is used. A reinforced fiber may be formed of silicon carbide fiber and the like. A reinforcing member may be formed of particle such as SiC. A matrix metal may be formed of right alloy such as aluminum alloy or magnesium alloy. After the shaft part is formed by the material, the umbrella part is upset. The MMC applied to a valve face part is manufactured from a rapid cooling coagulum aluminum in which nitride or boride is dispersed by means of a powder method, and the MMC is inserted and mounted on a part corresponding to the face part in a casting type. It is thus possible to provided an intake valve having good abrasion resistance and heat transmitting performance without using an iron system material.

Title: Oscillator
Inventor: YOSHIDA OSAMU
IPC: H03K5/08
Filed: 1986-09-09
Abstract: PURPOSE:To prevent an oscillation output signal from being outputted to the outside until oscillation becomes stable by making the threshold value of a NOT circuit which constitutes an oscillation part different from the comparison value of a comparison part which inputs the oscillation output signal of the oscillation part. CONSTITUTION:An oscillation part output signal v1 increases gradually from a small amplitude based principally on the threshold value (threshold value of the 1st NOT circuit) of an MOS TR Q1 to a large amplitude and when the peak reaches the threshold value (threshold value of MOS TR Q3) of the 2nd NOT circuit, the 2nd NOT circuit outputs an impulsive signal v2. A detection part 2 outputs 0 until three pulses of the signal v2 are inputted and then outputs 1 thereafter and when the output signal of the detection part 2 becomes 1, a NAND circuit 3 passes (by inversion) the output signal of the 3rd NOT circuit (MOS TR Q5). Consequently, a device output signal v0 is outputted for the 1st time after the oscillation of the oscillation part 1 becomes stable after the oscillation is commanded with a reset signal vr.

Title: Recirculation of coal hydrogenation catalyst
Inventor: TAMURA NOBUHIRO
IPC: B01J23/00
Filed: 1982-12-07
Abstract: PURPOSE:To make it possible to economically perform a coal hydrogenation process, in liquefying coal by reacting coal and hydrogen in the presence of a ferrous catalyst, by subjecting obtained formed crude oil to gravity concn. treatment while recirculating a lower oil layer to a coal hydrogenation process to reuse the same. CONSTITUTION:In liquefying coal by reacting coal and hydrogen in hydrocarbon oil at high temp. under high pressure in the presence of a ferrous catalyst, the obtained formed crude oil is subjected to gravity concn. treatment while a high pressure atmosphere is held to form a lower oil layer in which a relatively large amount of a catalyst particle and ash in an amount not exceeding 70% of ash contained in the crude oil are suspended and this lower oil layer is recirculated to and used in a coal hydrogenation process while separated from the upper oil layer reduced in the amount of the catalyst particle. That is, the greater part of the catalyst can be recovered around a reactor and it is available from the standpoint of heat energy conservation. In addition, because separation is performed at a high temp. by a low viscosity slurry, there is no defect related to separation operation. Further, it is economical because the separated and recovered catalyst slurry is directly used.
