Title: Production of double oxide based superconducting thin film
Inventor: ITOZAKI HIDEO
IPC: C01G3/00
Filed: 1988-02-05
Abstract: PURPOSE:To produce the titled thin film having the high superconducting critical temperature, by carrying out sputtering using a target consisting of a blend of compounds containing La, a specific element and Cu. CONSTITUTION:A blended powder of 70-95wt.% La2O3, 1-20wt.% compound (e.g. SrCO3) of one element (M) selected from group Ia, IIa and IIIa elements of the periodic table and 1-30wt.% CuO is pressed by powder hot (hydrostatic pressure) pressing and sintered to provide a target 3, which is then placed in a bell jar 1 to evacuate the interior thereof through a gas discharge hole 7. An inert gas and O2 are subsequently introduced from an introduction port 8 to adjust the oxygen partial pressure to 10<-6>-5X10<-2>. High frequency at <=5,000W is then applied from a high-frequency power source 3 to the target 2 and a bias voltage of 0-500V is simultaneously applied through a power source 5 and a heater 6 to a substrate 4 to heat the substrate at 100-1,200 deg.C. The target 2 is then sputtered to form a superconducting thin film at an atomic ratio expressed by the formula (0<x<1; 0<=y<4) on the substrate 4 and the resultant superconducting thin film is subsequently heat-treated at 600-1,200 deg.C.

Title: Control device of internal combustion engine
Inventor: TAMURA HIROSHI
IPC: F01N3/24
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To prevent burning and deterioration of a catalyst due to misfire. SOLUTION: A throttle opening characteristic is gradually changed from characteristics A to characteristics B at the point of time when catalyst temperature exceeds 700 deg.C at the time when misfire is caused, and accordingly, a throttle opening is closed in accordance with the characteristics B. Consequently, unburnt gas flowing into the catalyst and burning at the time when the misfire is caused decreases and rise of the catalyst temperature becomes lenient. Thereafter, at the point of time when the catalyst temperature exceeds 800 deg.C, the throttle opening characteristics are gradually changed from the characteristics B to characteristics C, and accordingly, the throttle opening is further closed. Consequently, it is possible to restrain rise of the catalyst temperature as the unburnt gas burning in a catalyst further decreases.  By such throttle control in accordance with the catalyst temperature, even when an accelerator pedal is continuously stepped on, the catalyst temperature does not exceed an allowable upper limit, and accordingly, it is possible to prevent burning of the catalyst and to stably maintain exhaust gas purifying performance of the catalyst for a long period of time.

IPC: B23K9/26
Filed: 1988-02-04
Abstract: PURPOSE:To prevent a water leak at the time of attaching or detaching operation of a changing part by providing a cooling water-gas substituting mechanism to substitute gas for the circuit inside for cooling water before attaching or detaching operation of the changing part to a water supplying and draining mechanism for cooling. CONSTITUTION:A solenoid valve 16 is operated to communicate a pipe 14 with a pipe 15 and a pump 17 is operated before or after this operation. By this method, the air is flowed in the pump 17 via the pipes 14 and 15. The air compressed by the pump 17 is discharged to the pipe 18 side and the cooling water in the circuit for cooling water is pressed out by the compressed air. The changing part such as a nozzle 5 or an electrode is attached or detached. By this method, since the cooling water can be drained practically from the circuit inside for cooling water before attaching or detaching operation inside for cooling water before attaching or detaching operation of the changing part which is water-cooled directly by the cooling water-gas substituting mechanism, the water leak at the time of attaching or detaching operation of the changing part which is water-cooled directly can be prevented.

Title: Automatic transmission for vehicle
Inventor: KASHIWARA TADASHI
IPC: B60K20/00
Filed: 1983-02-17
Abstract: PURPOSE:To provide an automatic transmission having a simple structure with no clutching operation, by frictionally engaging an axially movable speed change ring with the conical surfaces of plural conical rollers for carrying out planetary movement. CONSTITUTION:A transmission having conical rollers 9 each of which is formed with a first frictional transmission surface 3 engaged with a transmitting wheel 2 fitted onto an input shaft 1 and a second frictional transmission surface 6 engaged with a transmitting wheel 5 fitted onto an output shaft 4, in addition to a conical surface 8 engaged with a speed change ring 7. When the speed change ring 7 is moved in the direction in which the effective diameter of the conical surface 8 is increased, the rotational speed of the output shaft decreases. This action is due to frictional force between the conical surface and the speed change ring. When the speed change ring 7 displaces to the lower section of the conical surface, the rotation of the output shaft stops so that this action makes effective in establishing the condition equivalent to the condition of disengaging of a clutch.

Abstract: PURPOSE: To prevent intrusion of vaporized fuel into an intake system by detecting the scarcity of the vaporized fuel amount by means of the temperature of fuel and the vapour pressure in vaporization source and cutting-off the intake negative pressure passage of a purge controlling valve by means of a electromagnetic valve.  
     CONSTITUTION: The fuel vaporized in a fuel tank 1 is drawn into a storage space 8 from the upper space 5 of a canister 4 through a check valve 2 and an absorbing passage 3, and adsorbed onto adsorbent. If the amount of vaporized fuel in the fuel tank 1 is little, or the fuel temperature is low, a temperature sensitive switch 42 is off, and the solenoid 31 of an electromagnetic valve 30 is not energized, so the intake negative pressure passage 25 of the purge controlling valve is intercepted, and the chamber 24 is caused to open to the air. Accordingly, the vaporized fuel is  purged only through an orifice 26, and the intake of purge air into an intake passage 13 can be prevented. On the other hand, when the temperature sensitive  switch 42 is turned-on, the electromagnetic valve 30 is opened, and the amount of  purge is controlled by a valve 11.
