Title: Ac power supply device
Inventor: MORIYA FUMIYASU
IPC: H02M7/497
Filed: 1979-07-09
Abstract: PURPOSE:To obtain an AC power supply device having high voltage DC as a power source by using switching elements as small number as possible by connecting two inverter circuits to a DC power supply, and commonly connecting the secondary sides of transformers correspoding to the respective circuits. CONSTITUTION:Inverter circuits IV1, IV2 formed of 6-phase bridge circuit of high harmonic wave current preventive reactor L1 and capacitors C1, C2 of series circuit are connected through a high velocity breaker HB to a DC power supply ED, and the neutral point P1 of the capacitors C1, C2 is connected to the midpoint P2 of two sets of bridge circuits. The outputs of the inverter circuits IV1, IV2 are synthesized through transformers T1, T2 to 3-phase AC to obtain an output voltage V0. Both the transformers are so wound and determined in winding type that the respective load capacities become equal to each other simultaneously when the inclusive high harmonic waves become less. In this manner it can obtain an AC power supply device having high voltage DC as a power source by using switching elements as small number as possible and can still obtain equivalent performance to the conventional one in waveform distortion rate.

Title: Picture processing circuit
Inventor: SATO SHIGERU
IPC: H04N7/00
Filed: 1991-03-27
Abstract: PURPOSE:To improve the resolution with one picture memory by making the frequency of the synchronizing signal of an input picture and that of an output picture of the picture memory different from each other and stopping read to write the input picture in the blanking period of the output picture. CONSTITUTION:A write counter 12 is used to designate an address of a picture memory 11 and is controlled by the synchronizing signal of the input picture and counts picture element clocks of the input picture. A read counter 13 is controlled by the synchronizing signal of the output picture, whose frequency is different from that of the synchronizing signal of the input picture, and counts picture element clocks of the output picture. Though a selector 14 normally selects the counted output of the counter 13, the selector 14 selects the counted output of the counter 12 to transfer it to the memory 11 when a signal indicating the blanking period of the output picture is outputted. Thus, it is unnecessary that the access time of the memory 11 is especially short, and the resolution is improved with one memory 11.

Abstract: PURPOSE:To obtain a sludge hardener and a soil conditioning material from slug, by adding 5-30wt% of silicate to high basicity steel making sludge held under a molten state to generate melting reaction while adding gypsum or lime to the reaction mixture before crushing. CONSTITUTION:5-30wt% of one or more of silicate selected from rock, mineral, coal ash, waste brick and waste casting sand is added to high basicity steel making slug held under a molten state to generate melting reaction and the resulting mixture is subjected to water granulation treatment before drying. Subsequently, 3wt% of gypsum or lime is added to the treated sludge to crush the same. When a small amount of an alkali stimultaing agent such as CaO is added to this crushed materil and water is further added thereto to perform kneading, said crushed material becomes hydraulic and, therefore, can be used as a sludge hardener. As additives, Al2O3 or SiO2 may be used alone but it is pref. to add an additive in which a proper amount of SiO2, Al2O3, Fe2O3 or the like are contained because melting temp. is lowered.
