Title: Dc thyristor circuit breaker
Inventor: NAKATSU KEIJI
IPC: H01H33/59
Filed: 1984-03-16
Abstract: PURPOSE:To simplify the constitution of a DC circuit breaker and to attain miniaturization and low cost by using two anti-parallel thyristors to supply power between two power supplies and using in common one set of communication circuit at the interruption of the thyristors. CONSTITUTION:In supplying power from the 1st converter 10 to the 2nd converter 11, the 1st SCR20 is turned on. In interrupting the power, a reverse current SCR22 and a resonance current SCR26 of the commutation circuit are turned on and the 1st SCR20 is turned off by supplying the reverse current to it from a commutation capacitor 5. When the resonance current is zero, the SCR22, 26 are turned off. On the other hand, in supplying power from the 2nd converter 11 to the 1st converter 10, the 2nd SCR21 is turned on. In interrupting the SCR, a reverse current has only to be supplied to the SCR21 by turning on SCR 23, 27. Since the commutation circuit is used in common, the miniaturization and light weight of the circuit are attained and the cost is made inexpensive.

IPC: A61H39/06
Filed: 1986-03-09
Abstract: PURPOSE:To obtain an excellent material for moxa cautery exhibiting synergistic effect of conventional moxa and germanium and having excellent heating effect as well as permeation effect of organic germanium compound, by mixing a germanium compound to moxa or basidiomycete. CONSTITUTION:A germanium compound is included in moxa or basidiomycete e.g. by spraying and impregnating a germanium compound to moxa or basidiomycete or applying a germanium compound in the culture of basidiomycete to effect the absorption of the germanium compound to basidiomycete. Germanium has skin stimulation effect and permeates into the skin. A moxa produced by this process has excellent combustion property and gives mild heat-stimulation for longer time. Basidiomycete can be directly ignited and has higher heating effect than mugwort moxa. The impregnation effect of organic germanium assimilated by the basidiomycete can be expected.

Filed: 1995-03-10
Abstract: PURPOSE: To easily discharge gas accumulated in the upper part of a filter by rotatably supporting the filter by arms and supports installed on side surfaces thereof and inverting the filter in the early stage of the filter operation to discharge gas. CONSTITUTION: Two arms 10 are fixed and fitted onto the side surface of an outer cylinder in symmetric places to the central axis of the outer cylinder. The end part 11 of each arm 10 is formed into a cylinder, and a projecting part projecting sideway of the upper part of each support 12 is inserted into the cylinder. Therefore, a filter body is rotated around the arm 10 in a vertical place. When a pump is operated in the state the filter is held in a normal position to feed a coating material, and the coating material spreads all through the filter, then the filter body is rotated to direct a filter withdrawal port upward. Then, gas in the filter flows out together with the coating material, and after that, the filter body is again rotated and is returned to its normal position.  Thus, since gas flows out from the filtrate withdrawal port, the coating material blows out together with the gas to cause no contamination of the surroundings.

Abstract: PURPOSE:To obtain an improved picture with an improved S/N ratio by installing a sample holding circuit, which retains the output of a detector by sampling the said output by means of sampling signals synchronized with a circuit driving a sample. CONSTITUTION:After an electron beam is irradiated on the LSI board 53 or the like by means of an electron-beam irradiating part 52 installed within a scanning electron microscope 51, secondary electrons generated at the electric potential of the board 53 are detected by a detector 54, and are sent into a sample holding circuit 56.
