Title: Rotary speed setting circuit for turbine governor
Inventor: WATARAI YUICHI
IPC: F01D17/24
Filed: 1987-09-01
Abstract: PURPOSE:To prevent overexcitation of a transformer or the like in an electric power system in which a turbine generator is incorporated by fixing a condition at the time of completing the speed up of a turbine and a lower limit speed preset value. CONSTITUTION:In a governor of a turbine, OR circuits 24, 26 for giving an up command and a down command are connected to a rotating speed setting device 10. The down command is input to the setting device 10 through a wipe- out circuit 52 controlled by AND circuit 50. An excitation on-operating signal as a speed up completion signal of the turbine and a lower limit speed preset value are input to AND circuit 50, and the AND circuit 50 is adapted to output a down command only when both conditions are satisfied. Thus, the turbine is interlocked so that the rotating speed preset value will not become less than the lower limit value to prevent overexcitation of a main transformer or the like.

Inventor: HIRANO YOSHINOBU
IPC: E04F15/12
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To prepare a large amount of self-fluiding hydraulic composition having very fast hardening property in a short time by transporting it to a jobsite in a form of powder, and kneading it with water by a continuous kneading method to prepare slurry so as to be flowed in at the jobsite. SOLUTION: A continuous kneading method uses a kneading mixer provided with a powder-supply feeder and a device for supplying quantity of water with a water meter capable of the continuous supply of self-fluiding hydraulic composition powder. The ratio of water to powder can be substantially constantly kneaded by controlling the powder-supply feeder and the water meter mounted on a kneader, and slurry having a constant flow value is continuously supplied. The flow value of slurry is preferably 190-250 mm. A large amount of self- leveling material slurry whose secular change of the fluidity is large can be prepared at a jobsite.

Title: Nonvolatile semiconductor storage device
Inventor: KANAZAWA KENICHI
IPC: H01L29/788
Filed: 1988-08-30
Abstract: PURPOSE:To write to only selected cell transistors by making the channel length of a cell transistor that goes away from the drain contact hole and comes toward the source line appropriately smaller. CONSTITUTION:The channel lengths 17a, 17b, 17c, 17d of respective cell transistors TR 14a, 14b, 14c, 14d are made smaller so that the channel length 17a > channel length 17b > channel length 17c > channel length 17d as they go further away from a drain contact hole 9 and come closer toward a source line 2a. Let us take an example of writing to the TR 14a. Although the channel length 17a of the TR 14a is made larger with respect to those of the TRs 14b, 14C, 14d, there is no voltage drop, and therefore it is possible to properly write to the TR 14a. On the other hand, the channel lengths of the other TRs 14b, 14c, 14d are made smaller as they go further away from the drain contact hole 9 so that it is easy to write to them. The writing to the TR 14a causes only a few voltage to be applied to the drain. Thus, there is no writing taking place.

IPC: G01S11/12
Filed: 1991-08-28
Abstract: PURPOSE:To achieve stable tracking of an image by providing an image tracking means, a distance detecting means and a position correcting means of a window to detect a vehicular gap. CONSTITUTION:A window 14 which is adapted to surround an advance vehicle image 5a viewing the advance vehicle image 5a displayed on a display screen 11 is set and a tracking indication switch 13 is operated. The tracking of an image is started automatically after the position of the window 14 is corrected to contain the advance vehicle image 5a exactly within the window 14. A microcomputer 10 reads out a pixel signal within the window 14 tracking the advance vehicle image 5a from a memory 8 to make a reference image signal for the computation of a vehicular gap. An image signal of the image sensor 4 on a memory 9 is stored. Upper and lower pixels are compared and (n) is given as quantity of shift of pixels when the sum of absolute values of the resulting difference signal thereof is at its minimum. Thus, when the pitch of the pixels is represented by P, a base line length of an optical system by L and focal lengths of lenses 1 and 2 by (f), a distance R to the preceding car is determined by the formula of R=fXL/nXP.

Title: Method of controlling glow plug for diesel engine
Inventor: OGAWA TOSHIHISA
IPC: F02B3/06
Filed: 1982-12-13
Abstract: PURPOSE:To improve accuracy by carrying out analog-digital conversion of voltage relating to the terminal voltage of glow plugs during the period at which a power amplifier is conducting and detecting the temperature and comparing it with the target temperature. CONSTITUTION:A current detecting resistor 2 is connected in series to glow plugs 1 and the voltage at a node 20 is transmitted to an A/D together with signals from a water-temp. sensor 22. A power amplifier 3 receives control pulse signals from the duty port section of an input-output port 16 through a drive circuit 23 and carries out duty control. At this time, the temperature can be detected based on the voltage after a lapse of defined time during which a glow plug conducting current becomes constant, thereby enabling further accurate control of temperature.

IPC: B23K9/073
Filed: 1992-08-17
Abstract: PURPOSE:To solve the large capacity and high price of an auxiliary power source circuit, which executes arc regenerating and its smooth maintenance at polarity reversing in a consumable electrode AC arc welding machine. CONSTITUTION:A straight polarity superimposing circuit part 19 charges a straight polarity capacitor in the reversed polarity period, this electric charge is supplied, in the next straight polarity period, to a welding arc part 14 as restriking voltage through the first straight polarity switching element 9.

Title: Intake apparatus for rotary piston engine
Inventor: TADOKORO ASAO
IPC: F02B27/00
Filed: 1982-12-10
Abstract: PURPOSE:To raise the charging efficiency of an engine and to thereby prevent drop of the engine output in the operational range of the engine when switching of a variable port is effected, by opening a second intake port fully at the time of high-load operation of the engine simultaneously with the opening of a control valve, and delaying the timing for closing the second intake port when the control valve is opened to that of a first intake port. CONSTITUTION:The engine speed for switching a second intake port at the time of high-load operation of an engine is set in the range of 3,500-5,000rpm since it is necessary to keep a control valve open at the time of engine operation higher than 5,000rpm and to close the control valve for preventing blow-back of intake air when the engine speed is lower than 3,500rpm. The timing for closing the second intake port when the control valve is open is delayed to that of a first intake port so as to raise the charging efficiency. At the engine speed for switching a variable port when a high-load intake port 4 is opened, expansion wave is produced in a first and a second low-load intake passages 20a, 20b when supply of intake air from a low-load intake port 3 is started and transmitted as secondary pulsation wave of compression wave to the low- load intake ports 3 of cylinders 1A, 1B just before they are closed completely. By thus supercharging the engine and raising the charging efficiency, it is enabled to increase the engine output by preventing the drop of the same.

Abstract: PROBLEM TO BE SOLVED: To secure an equivalent wall thickness and to make the shape of an apex part stable by a method in which an excess thickness is made on the outside of the apex part of a basis body, and the excess thickness is biased to the longitudinal side and is baking-deformed to the short hand side. SOLUTION: When a basis body 1 having plane parts 14, 15 of a short hand and a long hand located perpendicularly is mounted on a baking base and baked, the basis body 1 is expanded in the longitudinal direction, in the width direction, and in the thickness direction to make a sintered body 2. During the expansion, the back if the basis body 1 is mounted on the plane part of the baking base, the expansion in the thickness direction expands to the surface side, and no large change takes place in the back.
