Title: Operation control method of distributed power supply equipment
Inventor: MATSUKAWA MITSURU
IPC: H02M7/493
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To realize a parallel synchronous operations of respective distributed power supply devices, when the respective distributed power supply devices are paralleled off from a power system into self-contained operations, while synchronism is not obtained by exchanging information on output powers, output currents, etc., between the distributed power supply devices. SOLUTION: When a plurality of distributed power supply devices (solar generators 1) which are paralleled off from a power system 5 are put into self-contained operations, an inverter 3 of one of the respective distributed power supply devices is used as a reference inverter. The reference inverter is operated by a voltage control operation to form an AC voltage source. After the reference inverter generates a voltage, the inverters 3 of the remaining distributed power supply devices are operated by current control operation synchronously with the output voltage of the reference inverter. Through the current control operation, AC-current sources synchronous with the AC voltage source are respectively formed, and the parallel synchronous operations of the respective distributed power supply devices are realized.

Inventor: ONISHI SHIGERU
IPC: F02B75/12
Filed: 1985-11-12
Abstract: PURPOSE:To improve a rate of air utilization and shorten the period of time for combustion by striking injected fuel in a solid state against the inside of a cavity centering a struck section so as to attain a three dimensional combus tion of multi-layer multiple point ignition in respective processes of diffusion and evaporation. CONSTITUTION:Injected fuel from a fuel injection nozzle 4 is struck in a solid state against the inside of a cavity 7 for being diffused while being distributed in an entire area of the cavity 7 centering a struck point. And in respective processes of diffusion and evaporation, a three dimensional combustion of multi- layer multiple point ignition is attained for improving a rate of air utilization without depending on swirls so as to shorten the period of time for combustion. In this case, a needle valve with a single hole nozzle having a spray angle of less than 10 deg. is usable for stricking injected fuel against the top face of a projection provided to a piston or the cavity 7. This constitution can speed up the reaction of combustion and improve a rate of air utilization for employing a direct injection type diesel engine, which has an advantage in thermal efficiency, of a small size and high speeds.

Title: Moving distance measuring instrument of numerical controller
Inventor: OTSUKI TOSHIAKI
IPC: G05B19/4155
Filed: 1984-11-30
Abstract: PURPOSE:To obtain immediately an accurate moving amount by providing a storage means storing a feeding speed, an acceleration/deceleration time constant, a servo time constant and a delay time of the reception system of a skip signal so as to correct automatically measuring error due to a delay in acceleration/deceleration or a servo mechanism. CONSTITUTION:A tool is moved toward the axis X in a feeding sped Fm. A position counter 24 counts an output of a distribution circuit 17 to revise the position of a reference point 0 viewed from from the numerical 17 to revise the position of a reference point 0 viewed from the numerical controller. The content of the position counter 24 does not accurately represent the position of the reference point 0 during the movement. When the tip of the tool 1 is pressed into contact with a touch sensor 3, a CPU reads a position Px when viewed from the numerical controller of the reference point 0. Since some delay time exists, the read Px does not represent the actual position Px' but gives a value subjected to some lead. The CPU 10 obtains the moving amount P of the reference position 0 viewed from the numerical controller by subtracting the P0 from the Px to calculate the actual movement Pn. Since the Pn is added with the correction for moving sped of the tool, the Pn is very close to the actual moving amount P'.
