Title: Reactive injection molding method using prefoam
Inventor: KITA TETSUO
IPC: B29C45/00
Filed: 1989-06-21
Abstract: PURPOSE:To make air bleed possible without raising a mold, and reduce the size of a whole apparatus and the number of processes by sucking out air and decompressing in the cavity via air bleeding holes formed in the position to which an injected reactive injection molding material reaches, after that, injecting the reactive injection molding material therein. CONSTITUTION:A prefoam P is held in a cavity 11, and a mold 10 having decompressing air bleed holes 12, 12 is fitted therein. The injection holes 13, 13 for a reactive injection molding material Z are formed in the lower side of the mold 10. Decompression is performed in sucking out the inside air within the cavity 11 via the air bleed holes 12, 12, and while keeping the decompressed state, an article is manufactured in injecting the reactive injection molding material Z into the cavity 11. At this time, the inside air within the cavity is pushed out by the flow of the reactive injection molding material and discharged spontaneously from the air bleed holes 12, 12 to the outside. Accordingly, the air bleed in the cavity 11 can be conducted without raising the mold, thus, it becomes unnecessary to provide a mold raising device.

Abstract: PURPOSE:To increase cooling water circulation amount to a radiator by regulating rotation of an electric fan provided adjacent to the radiator and restricting heat release amount at the time when the temperature of cooling water rises and by cancelling a thermo-valve to the low temperature side and driving it after the temperature of cooling water rises. CONSTITUTION:A thermo-valve TV is arranged at one end opening part of a by-pass passage 25 which by-passes a radiator 4 and passes through a plural number of cooling water passages 6, 13. Then the thermo-valve TV is driven and controlled by a control means C through an actuator 35 on the basis of a detection signal from a load detection means A for an engine E. In this case, when the temperature of cooling water becomes higher than the rotation starting temperature of an electric fan 45 on the basis of a detection signal from a temperature detection means B for the cooling water passage 6 on one side, the actuator 35 is cancelled and driven to the low temperature side with a means F. Additionally, even when the temperature of cooling water is high, the rotation drive of the electric fan 45 is regulated with a means G in the state of low load.

Title: Internal combustion engine
Inventor: YOSHIZAKI KOJI
IPC: F01N3/08
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To release NOX from an NOX absorbent perfectly even when an appreciably lean air-fuel ratio is changed to a rich air-fuel ratio. SOLUTION: A selection is made from first combustion where an EGR gas quantity within a combustion chamber 5 is more than an EGR gas quantity with the peak generation of soot and thus generates almost no soot and second combustion where the EGR gas quantity within the combustion chamber 5 is less than the EGR gas quantity with the peak soot generation. An NOX absorbent 22 is placed in an engine exhaust passage. When the air-fuel ratio is to be enriched in advance of the release of NOX from the NOX absorbent 22 when the second combustion is changed to the first combustion, the injection quantity and the injection period are both increased as compared to those when the air-fuel ratio is to be enriched during the first combustion.

Title: Formation of oxide film
Inventor: MORITA YOSHIO
IPC: C23C18/12
Filed: 1986-07-07
Abstract: PURPOSE:To form a uniform oxide film on the surface of a wide range of objects regardless of the specific surface areas thereof by heating a water soluble compd. to constitute the oxide film and non-neutral aq. soln. of urea, depositing a hydroxide film by the decomposition neutralization reaction of the urea and subjecting the film to heating and calcination. CONSTITUTION:The hydroxide deposits gradually as a covering on the surface of a substrate by the neutralization reaction by the carbonic acid or ammonia generated on progression of the hydroxysis reaction of the urea when the above- mentioned aq. soln. is heated. Since the neutralization reaction progresses indirectly with the rate of the hydrolysis reaction of the urea as a rate- determining factor, the forming speed of the hydroxide is easily controlled and the formed hydroxide is selectively or at least preferentially deposited on the substrate surface, by which the film is obtd. The deposited hydroxide film is heated and calcined to the dehydration temp. or above to obtain the oxide film. Since the above-mentioned reaction is the reaction in the isotropic aq. soln., the formation of the uniform film is permitted regardless of the shape and size of the substrate.
