Title: Method for sorting aerosol fine particle by particulate diameter using uniform electrostatic field
Inventor: GOTOU MAKIMI
IPC: B01D57/02
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To form a uniform electrostatic field in a direction in which a charged particle migrates and also form the uniform flow of a gas by making a part which forms the electrostatic field a gas formed of two parallel plain plates and setting the gap to be of an annular structure. SOLUTION: An electrostatic field is formed into a rectangular ring gap 1 between a conductive plain plate 2 as an inside square pipe and a conductive plain plate 3 as an outside square pipe. In addition, a pure gas is caused to flow into the gap 1 in the form of a laminar flow. On the other hand, an aerosol 11 is caused to flow into the electrostatic field through a slit-like aerosol inflow aperture 4 opened at right angles with a direction in which the aerosol 11 flows in the upstream part of the inside conductive plain plate 2 and thus the charged particle in the aerosol begins to undergo an electrophotoretic process. A vent 5 from which the aerosol which is classified and separated by the electrophoresis is extracted is provided, in the form of a slit, in the downstream part of the outside conductive plain plate 3.  Consequently, the uniform electrostatic field in a direction in which a charged particle migrates and the uniform flow of the gas are achieved.

Inventor: SAKURAI KAZUO
IPC: C23C22/24
Filed: 1989-10-18
Abstract: PURPOSE:To oxidize Cr(III) to Cr(VI), to restore the performance of a liq. colorant and to regenerate the colorant by adding a specified amt. of H2O2 when the colorant for stainless steel obtained by dissolving sulfuric acid, chromic acid or a Cr(I)-contg. material such as chromate into water is deteriorated. CONSTITUTION:A stainless steel is dipped in an aq. soln. of sulfuric acid and a Cr compd. contg. Cr (VI) such as CrO3 and chromate to form a thin film of the oxides of Cr and Fe on the surface of the steel, and the steel is colored. As the colorant increases in amt., Cr (VI) in the colorant is reduced to Cr(III), the Fe in the steel is dissolved to generate Fe(III), and the coloring capacity is reduced. Accordingly, H2O2 to the ions of Cr(III) and Fe. Consequently, Cr(III) is oxidized to Cr(VI), Fe(III) is deposited as Fe2O3 and removed, and the coloring capacity regenerated and is restored.

Abstract: PURPOSE:To form a small unevenness in an optional shape on a cutting face according to the laser output state of a working pulse and to form an antiskid face by setting the value of the AC voltage impressing on a laser oscillator in two ways and alternately outputting them from a power source device. CONSTITUTION:A laser output is alternately commanded to a control device 3 from a laser output command circuit 2 by synchronizing with a pulse frequency. The control device 3 outputs a high frequency current while being command to output the laser output and outputs a high frequency current while receiving the output command of the laser output. Since the output high frequency current is alternately output according to a laser output command like this the pulse current having different current value is outputted, attaining to a discharging current. A power unit 4 impresses the high frequency voltage corresponding to each current value of a pulse like discharging current to a laser oscillator 1 alternately. As a result, the laser oscillator 1 repeatedly outputs two ways of laser outputs each constant time.

IPC: H02J1/00
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To prevent a control FET(field-effect transistor) from being broken as a result of an excessive current flowing into the control FET, due to the discharge current of a smoothing capacitor. SOLUTION: A control FET 8 can be operated in an area of safe operation and prevented from being broken by limiting the current flowing into the drain of the control FET 8 to current in rating of drain current of the control FET 8 by a resistor 14 inserted in series with a smoothing capacitor 7 at the front stage of the control FET 8. In such a condition when current is flown rapidly into output, for example, in case the output terminal is short-circuited or the impedance of a load is suddenly decreased, excessive current is flowed into the control transistor 8 by the discharge current of the smoothing capacitor 7 positioned at the front stage of the control transistor 8. Therefore, it is possible to prevent the control FET 8 from being broken.

Abstract: PURPOSE:To provide a distribution valve by which a content can be easily transferred from a container to a bottle, and in addition which can transfer a content liquid in a container without leaving a residue. CONSTITUTION:A distribution valve is constituted of an internal member 2 which is screwed on the outside of a grommet 1 provided on a container, an external member 3 which is screwed on the outside of the internal member 2, and a stopper 4 which prevents the internal member 2 from being unscrewed from the grommet 1. When the external member 3 is rotated in the unscrewing direction to the internal member 2, under a condition in which the valve is attached to the grommet 1 on the bottom of the container, an opening 34 at the lower end of the external member 3 is separated from a closing part 26 of the internal member 1, and a content liquid passes between legs 25 of the internal member 2 and streams out from the opening 34. Since the rotation of the internal member 2 is limited or stopped by a stopper 4, the internal member 2 does not rotate together with the external member 3 when the external member 3 rotates. A protruding stripe 38 facing inside on the inner periphery at the upper end of an intermediate outer cylinder 33 is engaged with a protruding stripe 28 facing outside on the outer periphery at the lower end of an intermediate inner cylinder 24 to prevent the intermediate outer cylinder 33 from being removed from the intermediate inner cylinder 24.
