Title: Reproducer for still picture
Inventor: SHINYA KAZUO
IPC: G09G1/00
Filed: 1991-03-14
Abstract: PURPOSE:To prevent the burning of CRT by decreasing the brightness level of a still picture at the time of successively reproducing the same still picture of the specified brightness level. CONSTITUTION:When digital still picture data SO is outputted from a frame memory 14 with the order of 'picture 1', 'picture 2',... and length in terms of time, a microcomputer 18 outputs the change detecting signal S4 of a low(L) level in the shape of a pulse at the changing time point of the respective still pictures so as to measure time from the generation time point of the L level pulse. When the reproduction of the same picture continues for more than specified time after the change detecting signal S4 becomes the L level like the case of 'picture 5', the microcomputer 18 outputs a time detecting signal S1. Then, NAND circuit 20 generates an output signal S3 so that the output signal S5 of a flip-flop circuit 21 becomes high(H) level and a video demodulation circuit 16 decreases the brightness level of an analog still picture signal S6.

Title: Control method for inverter
Inventor: FURUYA SHINICHI
IPC: H02M7/48
Filed: 1989-03-02
Abstract: PURPOSE:To inhibit a steep charging current from rushing into a load by operating a semiconductor switching element constituting an inverter connecting a capacitive load in a non-saturation region at the time of starting said inverter. CONSTITUTION:When an operation command is issued to an inverter, a conducting angle control circuit 33 gives a switch 36 an ON.OFF command by a signal from an integrator 32. The pulse width of an ON signal given to the gate of MOSFET via said switch 36 is initially very narrow but gradually spreads with the lapse of time. Also, a DC voltage outputted by a variable voltage DC power supply 35 after receiving the signal from said integrator 32 initially takes a low value but gradually increases said value with the lapse of time. In this manner, a semiconductor switching element operates in a non- saturation region so that a current charging a capacitive load is inhibited.

Title: Apparatus for reforming liquid fuel
Inventor: KOMATSU YOSHIHISA
IPC: C10G32/02
Filed: 1979-04-26
Abstract: PURPOSE: To reform liquid fuel so that, when the fuel is fed to an internal combustion engine, a boiler or the like, it can be divided into fine particles at the time of spraying or carburetion, and it can be perfectly burned, by applying ultrasonic wave and a voltage to the fuel while passing the fuel through a magnetic field of permanent magnets.  
     CONSTITUTION: 1 is a magnetic oscillator and as the oscillator, one having a Curie point higher than 300°C is used. 2 is permanent magnets, and when a voltage 3 is applied, the magnets change in electric charge to minus. A slit 4 between the two magnets is narrowed so that a strong magnetic field can be applied to the liquid fuel. The distance between the magnetic osicllator 1 and the slit 4 is maintained at a certain length so that, in the slit 4, complicated movement may result from the action of forwardly flowing ultrasonic wave stream upon the flow movement of lines of magnetic force and thereby the charging action may be promoted. By irradiating impurities contained in fuel with ultrasonic wave, the sludge can be dispersed in a finely divided form, and by passing fuel through the field resulting from an electric field and a magnetic field, the fuel can be reformed into finely divided charged particles and the efficiency of fuel can be improved.
