Inventor: KUREMENSU GURIIZAA
IPC: F02D41/14
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To avoid the damage or early deterioration of an exhaust gas treatment system by exceptionally setting an air-fuel ratio substantially to a theoretical air-fuel ratio or rich air-fuel ratio when the exhaust gas treatment system exceeds a prescribed temperature limit. SOLUTION: A multi-cylinder internal combustion engine 10 is controlled by an electronic engine control unit 12 receiving a plurality of input signals 24 such as engine rotating speed, accelerator pedal position and the like. The engine control unit 12 executes an algorithm for controlling an electronic throttle valve 20, an ignition system 18 and a fuel injection system 26. The exhaust gas temperature near an exhaust gas treatment system 28 is measured by use of a temperature sensor 22. When the exhaust air temperature exceeds a prescribed temperature limit, the transfer to lean burn operation or deceleration cut is not permitted. The operation substantially at a theoretical air-fuel ratio is performed in lean burn operation area or overrun operation area.  According to this, the damage or early deterioration of the exhaust gas treatment system at a damage temperature limit or lower can be avoided.

Abstract: PURPOSE:To uniformize coating by discharging an optimum amount of a coating solution by changing the discharge amount of the coating solution forcibly discharged from a nozzle corresponding to the coating stand-by time from the stop time of the coating due to the nozzle to the start time of the coating. CONSTITUTION:The coating solution supplied from a nozzle 8 is forcibly discharged in order to prevent the change of the characteristics of the coating solution supplied to an object 17 to be coated from the nozzle 8 to be applied thereto. The discharge amount of the coating solution forcibly discharged from the nozzle 8 is changed corresponding to the coating stand-by time from the stop time of the coating due to the nozzle to the start time of the coating. That is, a control part 16 controls the discharge amount of the coating solution discharged from the nozzle 8 to the optimum one on the basis of the coating stand-by time clocked by a timer 14 and the optimum discharge amount of the coating solution stored in a memory 15. As a result, coating can be uniformized.

Filed: 1989-08-10
Abstract: PURPOSE:To exhibit a high cushion property of a retainer in various directions by pressurizing a ring-shaped raw material which is formed of a flat metal-made filament curled lengthwise and wound and lapped several times. CONSTITUTION:A ring-shaped raw material 8 is formed by winding and lapping several times a curled filament 5A which is formed flatly and curl-worked in the longitudinal direction, to a winding shaft 7. After the ring-shaped raw material 8 is pulled out from the winding shaft 7, a retainer 5 is molded by pressurizing by a metal mold. In this condition, a ceramic honeycomb structure 3 is retained by interposing the retainer 5 between the outer circumference surface of the ceramic honeycomb structure 3 and the inner circumference surface of a metal-made casing 2. It is thereby possible to give a high cushion property having a large compression quantity and resuming quantity to the retainer 5 and also exhibit a high cushion property in various directions, since the ring-shaped raw material 8 is formed so that each curl part 5a of the adjacent filament 5A is confounded at random.

Abstract: PURPOSE:To decrease the dispersion of internal resistance by molding a positive- electrode active material in a cell case, then injecting an electrolyte, and reducing part of silver oxide into silver under this condition to get conductivity. CONSTITUTION:After a positive-electrode active material 7 made of silver oxide is molded in a cell case 8, an electrolyte is injected, about 3-5% of the silver oxide is electrically reduced into silver under this condition to get conductivity, then it is combined with a separator 5, an electrolyte impregnant 4, and a negative-electrode active material 2 stored in a sealing plate 1 to seal a cell via a packing 3. Accordingly, reduction is performed simultaneously with injection, the process is simplified and the cost is decreased, and the dispersion of the reduced quantity is made nearly zero by reducing the cell one by one, thus preventing the use of silver oxide more than required.

Title: High-order structure forming method
Inventor: YAMASHITA TERUO
IPC: H01B13/00
Filed: 1988-08-23
Abstract: PURPOSE:To form a structure having a high molecular order in a local region by applying a magnetic field to a superconductor of the second kind in such a way that a normally conductive region and a superconductive region coexist, depositing a molecule for forming the high-order structure under a vacuum atmosphere, and selectively sticking the molecule in either one of both regions. CONSTITUTION:An oxide high-temperature superconductor (a superconductor of the second kind) made of Ba2YCu4O7-x is prepared. The superconductor 6 of the second kind is cooled in liquid nitrogen L so as to be kept in a superconductive state under a vacuum atmosphere, and an external magnetic field is applied by a coil 7, so that a superconductive region and a normally conductive region may coexist in the superconductor 6. Molecular beams 9 for forming a high-order structure radiate from a molecular beam source 8 so that the structure having a high molecular order is formed on the superconductor 6. In the case that n-paraffin (diamagnetic molecule) is vacuum-deposited, the high-order structure is formed in the superconductive region. Therefore, the structure having a high molecular order can be locally formed.
