Title: Capacitor
Inventor: MIYAZAKI MASAHIRO
IPC: C30B29/06
Filed: 1989-06-22
Abstract: PURPOSE:To obtain a capacitor having high withstand voltage and large capacitance by forming silicon-oxide films to be utilized as dielectric films on both surfaces of an Si substrate and, at the same time, the Si substrate in a laminated state. CONSTITUTION:Dielectric films 6 of a silicon oxide and electric parts 8a are respectively formed on the upper and lower surfaces of a plurality of Si substrates 4 and surfaces of the films 6. Then the substrates 4 are piled up upon another in the thickness direction and the first electrode 8b is formed by electrically connecting the electrode parts 8a to each other, with the second electrode 10 being formed by electrically connecting the substrate 4 to each other. Since the silicon oxide forming the dielectric films 6 is compact and high in withstand voltage, the withstand voltage of this capacitor is improved. Moreover, since the films 6 are provided on both surfaces of the substrates 4 and the substrates 4 are piled up, the capacitance of this capacitor is increased by the multiple of the number of the substrates by two. Therefore, a capacitor having large capacitance and high withstand voltage can be obtained.

Title: Misfire detector of internal combustion engine
Inventor: YAMAMOTO KENJI
IPC: F02D45/00
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To always detect misfires occurring in an internal combustion engine with high accuracy irrespective of the running condition of the engine. SOLUTION: In the misfire detector of an internal combustion engine, a crank angular speed fluctuation amount is usually calculated for each cylinder based on a rotational angle signal NE corresponding to the rotation of a crankshaft and the occurrence of misfires in the engine is detected by comparing the calculated cylinder crank angular speed fluctuation amount with a specified misfire determination value. Here, under the condition that the engine is normally ignited, an inter-cylinder crank angle difference is calculated by an electronic controller 9 and the calculated crank angle difference is learned for each cylinder of the engine and each running condition.  On the other hand, in the electronic controller 9, a crank angular speed is calculated for each cylinder by correcting the crank angle difference based on learned values regarding each corresponding cylinder and each running condition of the engine and crank angular speed fluctuation amount for each cylinder compared with the misfire determination value is calculated based on changes in the obtained crank angular speed.

Title: Apparatus for stepwise controlling brightness of fluorescent lamp
Inventor: KAGEYAMA MOTOHIRO
IPC: H05B41/40
Filed: 1977-12-30
Abstract: PURPOSE:To eliminate delay in switching the operating mode of a fluorescent lamp between its full-lighted mode and brightness-controlled mode, by pre-charging a capacitor for determining the conduction phase angle to a certain voltage in lighting the lamp to its full capacity, and controlling a switching element at a predetermined conduction angle in switching the operating mode of lamp from its full-lighted condition to brightness-controlled mode. CONSTITUTION:When wall switch 4 is turned OFF and then turned ON again, in the state that changeover switch 6 is set at a brightness-controlled mode position X2, relay Ry is energized instantaneously at the time when the wall switch 4 is turned ON, since electricity in capacitor 22 is already discharged through resistance 21. Similarly, realy contact (r) is also closed instataneously, so that electricity in capacitor 3 is discharged through resistance 10. However, the capacitor 22 is then charged via power source E, a first contact 7 of changeover switch 6, capacitor 14, diode bridge 16, capacitor 3, diode 17, base emitter of transistor Tr, diode bridge 16 and power source E, so that conduction phase angle of switching element 1 is changed from its maximum to minimum.

IPC: F02C7/12
Filed: 1980-11-13
Abstract: PURPOSE: To enable the cooling of the turbine disc of a gas turbine in which a centrifugal compressor and a radial-flow turbine are placed back to back around a single axis and to simplify the cooling structure of the gas turbine.  
     CONSTITUTION: In the operation of a gas turbine, high-pressure air compressed by a centrifugal compressor 2 is used for combustion in a burner 19 and the combustion gas is ejected to a radial-flow turbine 3 to rotate a turbine disc 11 and an output shaft 1. At that time, some air always leaks along a non-contact seal 10 at the side of the compressor 2. Since the leakage air flows in the direction of an arrow in a fixed frame 9, the leakage air is guided to an inside opening 23 by an annular cover 20 so that the leakage air flows into a cooling passage 22 to forcedly cool the back of the turbine disc 11 to reduce the temperature rise of the disc. The leakage air is then discharged into a gas passage 15.

Title: Treatment device of evaporative fuel
Inventor: NAKANO MASARU
IPC: F02M25/08
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To improve fuel-adhesive and withdrawal performances of active carbons used in a treatment device of an evaporative fuel. SOLUTION: An evaporative fuel generated in a fuel tank 9 or the like is introduced into a vessel 3 which constitutes a canister C at the time of an engine stop. Granular adsorbents 18 of active carbons are packed in the vessel 3. The adsorbents 18 of active carbons are produced by adhering heat accumulating particles 18b comprising a metal or an inorganic material which has a higher heat transfer coefficient comparing with active carbons and a big heat capacity, almost uniformly, on the surface of a granular adsorptive base material 18a comprising active carbons. The evaporative fuel introduced into the vessel 3 is adsorbed by the active carbons in the adsorbents 18. The heat generated by the active carbons at the time of the adsorption is transferred to the heat accumulating particles 18b, so a temperature rise of the active carbons is suppressed.  The fuel adsorbed in the adsorbents 18 is withdrawn by introducing air from an air port 13 into the vessel 3 at an operation time of the engine, and sent to an intake pipe 12 of the engine and treated. A temperature decline of the active carbons at a withdrawal time of the fuel is prevented by taking away a retained heat of the heat accumulating particles 18b.

Title: Method and device for transmitting signal
Inventor: FUJITA YUZURU
IPC: H04J3/06
Filed: 1993-06-30
Abstract: PURPOSE:To transmit a high-speed data signal for a long distance by transmitting a clock signal while controlling the phase of the clock signal corresponding to a data signal corresponding to the distance of transmission and reception terminals on the transmission side, and fetching the data signal synchronously with the received clock signal on the reception side. CONSTITUTION:A data signal 301 of a short cable length can be exactly fetched by applying a clock signal 303 of a data transfer pitch (A) whose phase is synchronized with timing for arrival at the range of a required operation margin. Since a data signal 302 of a long cable length does not arrive at the range of the required operation margin at timing to input the clock signal 303, however, that data signal 302 can not be exactly fetched. By using a clock signal 304 of a data transfer pitch (B) at low transmission speed, however, the data signal 302 can be exactly fetched. Thus, the high-speed data signal can be stably transmitted for the long distance without thickening a cable diameter or increasing the physical amount of a transmission/reception circuit element or the like.

Title: Driving method of thin film el element
Inventor: KITA SUMIO
IPC: H05B44/00
Filed: 1977-12-28
Abstract: PURPOSE:To secure the luminance modulation through the pulse duration modulation by changing previously the voltage lower than the light emisson starting threshold level of the EL element to all picture elements on the selected scan electrodes. CONSTITUTION:Switches Sy1, Sy3, Syj, Sx1 ... Snk are turned on when the number of the data electrode is referred to as m and the number of one scanning electrode is n and the number of the selected picture elements is k at the driving time of one scan electrode. In this case, each picture element can be expressed by the equivalent circuits formed by capacity C1-C4. Difference Vs-Vp between writing voltage Vs and clamping voltage Vp is charged to all elements of scan electrode Y in the 1st timing, and then C1 and C2 are charged. No conduction is given via C2 when Vs is applied at the 2nd timing, and the time when the voltage of selected picture element C1 turns to Vs is always constant regardless of the number of the electrode of the matrix panel and the quantity of the data. The voltage of semi- selected picture element C2 and C4 becomes Vs-Vp and Vp respectively. And if Vp is selected properly to the level under the light emission threshold of the EL element, no light emission is obtained. In such constitution, the pulse duration can be modulated to perform the luminance modulation.
