Title: Power converter
Inventor: TANAKA SHIGERU
IPC: H02M7/48
Filed: 1994-05-18
Abstract: PURPOSE:To eliminate the fluctuation in DC voltage and to reduce the capacity of a DC smoothing capacitor by suppressing the fluctuation in the DC voltage of a main PWM converter which fluctuates due to the frequency which is twice the frequency of a single-phase AC power supply with an LC series resonance circuit and a DC active filter. CONSTITUTION:A compensation current IA flowing to a DC active filter DC-AF is detected by a current detector CTA and is input to a current control circuit ACRA. The current control circuit ACRA inverts and amplifiers the deviation (=I'A-IA) between a compensation current command value I'A, and the compensation current detection value IA and gives a voltage command value to a PWM control circuit PWMC3. A voltage-type PWM inverter VSI generates a voltage proportional to a voltage command value and controls the compensation current IA. The DC active filter DC-AF takes the compensation current IA=I'A =(Idc)-IFO and the LC series resonance circuit takes the IFO thus preventing the fluctuation component of a single-phase power from flowing to a main smoothing capacitor Cd and eliminating voltage fluctuation.

Filed: 1978-08-25
Abstract: PURPOSE: To prevent detecting capability from declining when the device is placed in a dark place by providing a quantum type infrared ray detecting element in such a way that it is sheilded from unnecessary external light rays and is placed in a heat insulation container to leep it cool, as well as by providing a white light source in the container where the source does not interfere.

A thin film 23 such as Al is coated on the inner surface of the glass container for sheilding external light. A filament of a light source 25 which irradiates white light on the detecting element 22, is sealed in the container 21. If the element is left in a dark place, its detecting capability drops because electron trapping level of an oxidized film on the surface becomes nil. Nevertheless, detecting with high capability is provided by turning on the light source, thus trapping the electrons beforehand.

Further, the ink 5 is transferred to the surface of a corrugated board sheet 4 which finds its way into a gap between a printing cylinder 3 and a receiver roll 7, and thus printing is performed as specified. In this case, a slightly higher static pressure is created in the interior compared to the ambience by injecting a clean air into an ink roll cover 8 from a pressure tank 9. After that, the clean air is ejected to an atmosphere from a gap between the ink roll cover 8 and the printing cylinder 3.  In this case, paper dust, paper scrap or scattered dust is prevented from sticking to the surface of the roll or being mixed into the ink 5 by a dynamic pressure.
