Title: Spark ignition cylinder injection type internal combustion engine
Inventor: YAMAMOTO SHIGEO
IPC: F02D41/04
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To inhibit the generation of knocking and reduce the fuel consumption by setting a target air-fuel ratio so that the injection fuel during an intake stroke comprises the air-fuel ratio more than the lean combustibility limits in a divided fuel injection mode where the fuel is divided into the compression stroke and the intake stroke for directly injecting the same into a combustion chamber. SOLUTION: An ultra-lean operation mode is selected by an ECU 16 which inputs the output signals of a throttle position sensor 37, a crank angle sensor 41 or the like, when the engine speed and the load of a cylinder injection engine 1 are small, and the mode is transferred to a divided fuel injection mode, a lean operation mode, a stoichiometric operation mode and an enrich operation mode in accordance with the increase of the engine speed and the load. A target air-fuel ratio is set so that the injection fuel in the intake stroke in the divided injection mode comprises the air-fuel ratio more than the lean combustibility limits free from the self-ignition, and the target air-fuel ratio in the intake stroke is gradually decreased toward the lean combustibility limits in accompany with the increase of the load correlation parameter.

Filed: 1987-12-12
Abstract: PURPOSE:To make an encoder compact, by integrally mounting the fixed slit pattern, which is formed from a pattern wherein the light non-transmitting and transmitting patterns formed on the light detection surface of a photodetector are alternately arranged, to the photodetector. CONSTITUTION:In an encoder equipped with a photodetector 18 having a fixed slit pattern 20 integrally formed thereto, the light from a light emitting element 12 transmits through the slit of a moving slit plate 16 and the light transmitting pattern of the pattern 20 to reach a photodetector main body 22 and, therefore, an electric signal of moving detection by photoelectric conversion can be obtained. That is, since the moving slit and the light transmitting pattern of the pattern 20 are the same pitch, light is transmitted or blocked by the slit row of the pattern 20 with the movement of the slit plate 16 to output a sine wave like electric signal from photodetector main body 22. Since the photodetector 18 itself is integrally constituted of the pattern 20 and the photodetector main body 22, a means holding a fixed slit is dispensed with and the thickness of the encoder can be reduced.

Title: Gas-blast circuit-breaker for making and breaking reactor
Inventor: NAKAMOTO TETSUYA
IPC: H01H33/915
Filed: 1988-12-14
Abstract: PURPOSE:To prevent high-frequency big surge voltages from being generated, by finding both a stroke position by which reignition may not occur when a reactor is broken, and the time from opening of a contact to the stroke and controlling opening of the contact of the breaker in the title so that the reactor current comes to its zero point at the predetermined stroke. CONSTITUTION:In accordance with the density of gas and the pressure of a driving source, both a predetermined stroke by which reignition may not occur when a gas-blast circuit-breaker brakes a reactor, and the time from opening of a contact to this stroke are computed and the trip signal of the breaker is controlled so that an ac current comes to its zero point at the predetermined stroke. Since therefore the current always comes to its zero point at a proper stroke position, the cooling force of gas flow can fully be obtained, and the insulation restoring force between electrodes is increased, since a fixed arc contact and a movable arc contact are sufficiently separated from each other. Reignition may thus not occur between the electrodes of the breaker when a reactor current is cut off; high-frequency great surge voltages can be prevented from being produced.

Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To facilitate a removal processing of a binder for a ceramic molded body by providing at least one of a through-hole and unevenness in a surface of which at least a ceramic laminate is placed. SOLUTION: A through-hole 4 is provided in a flat plate part 2 and a protruded part 3 of a loading instrument, through which air flows into so that when a chip shaped ceramic molded structure 5 is placed on the loading instrument, the amount of air flowing among the molded structures 5 is increased. For this, a thermal decomposition reaction is likely to be produced and hence the binder can be rapidly removed. Further, a surface of a flat plate part 7 on which the ceramic molded bodies are placed is formed into an uneven shape. Also in the loading instrument 6, air is likely to flow into an uneven part 8 and hence the binder can be rapidly removed.

Abstract: PROBLEM TO BE SOLVED: To enable a user to confirm images of a desired dynamic image to be retrieved at arbitrary points of time at arbitrary time intervals by an arbitrary quantity by generating thumbnails of the moving picture between a start point and an end point inputted by an input means at specified time intervals and displaying them in the time elapse order at the same time. SOLUTION: The user selects a dynamic image to be displayed out of dynamic images recorded on an optical disk loaded in an optical disk drive by operating a keyboard or mouse (S11) and inputs a time interval of images by operating the keyboard or mouse (S12). A CPU generates thumbnails of the selected dynamic image at the inputted time interval (S13), displays the generated thumbnails in the time elapse order on a CRT, and finishes the process (S14). Thus, the CRT of the personal computer simultaneously displays the image thumbnails of the dynamic image having the specific intervals while arranging them in the time elapse order.
