Inventor: YOKOZEKI ICHIRO
IPC: H05B41/24
Filed: 1993-03-31
Abstract: PURPOSE:To prevent counter-recovery of a parasitic diode even when a mismatch is generated deliberately and to make possible dimming due to mismatch by providing a protection diode to hinder the current from flowing in the parasitic diode, and connecting this protection diode in series to a switching element which has parasitic diode. CONSTITUTION:When a motor 9 is driven in accordance with the dimming level and the capacitance of a capacitor Cs is increased or decreased, a mismatch is generated in a matching circuit 2, and the input to an electrodeless discharge lamp 1 decreases, and the lamp 1 is put in the dimmed lighting condition in accordance with the dimming level. This mismatching the involves possibility that parasitic diodes D1, D2 parallel with FET's 4, 5 go in counter-recovery condition, wherein however protection diodes D3, D4 in series to the 4, 5 are connected, so that flow of the circulation current is hindered forcedly. That is, the diodes D1, D2 are incapable of being in electric continuity, and the FET's 4, 5 are protected even at the time of mismatching. and it is possible to make dimming control free from any obstruction. As the protection diodes D31-D34, D41-D43, a plurality of diodes are put in parallel connections so that the regular direction current per diode is lessened to lessen the burden.

Title: Washer
Inventor: MORITA SHIGEMI
IPC: D06F33/02
Filed: 1988-03-28
Abstract: PURPOSE:To execute a washing at a midnight and at the time of sleeping without a trouble by setting the dead time period of a motor to be larger than the case of a standard course or setting the driving time period of the motor to be shorter than the case of the standard course and for an operation executing time, providing a particular course to be set larger than the case of the standard course. CONSTITUTION:Since a dead time period Tb of a motor 5 is larger than a dead time period T2 in the case of the standard course, a time, when the intensity of a water flow formed by the drive of the motor 5, consequently, the rotation of an agitating body 4 is attenuated, is made larger, and namely, a water flow weakening degree is made large. As a result, when the agitating body 4 is inverted from a positive rotation to a reverse rotation or from the reverse rotation to the positive rotation, the water flow is already weakened, a waving and a splashing can be suppressed, and the generation of a noise to accompany the waving and splashing can be suppressed. Thereafter, the washing operation is completed when an executing time Tc passes. In such a case, since the executing time Tc is made larger than an executing time T3 of the washing operation in the case of the standard course and a driving time period Ta of the motor 5 is made equal to a driving time period T1 in the case of the standard course, a washing effect is made above that in the standard course.

Filed: 1992-03-30
Abstract: PURPOSE:To provide a pressure regulating valve which can suppress the displace ment in the radial direction of a bellows or valve piece by the action of an inflow fluid, without suppressing the smooth extension/contraction operation of the bellows. CONSTITUTION:A bellows 3 is extended/contracted in the axial direction, i.e., in the valve opening/closing direction by the pressure difference between the inside and outside of the bellows 3, and the valve opening 21 on a fixed valve seat 2 is opened and closed by the spherical valve (valve piece 4) at the top edge of the bellows 3. When the valve opening 21 is opened, the fluid inside a valve piece 1 flows outside through a flow-out hole 16 from the valve opening 21, and the fluid flows in from the outside fluid space through an inflow hole 15. Since the inflow hole 15 is opened in the deflected direction for the centrifugal direction directing to the center axis of the bellows 3, also the direction of the energizing force generated in the case when the fluid which flows from the inflow hole 15 collides with the bellows 3 or spherical valve 4 deflects, and the vibration and curvature in the radial direction of the bellows 3 and spherical valve 4 are suppressed.

Abstract: PURPOSE:To obtain a full-color printer which stably provides high-quality print at low cost by providing a mechanism which changes a contact angle of a recording head with a resistance layer in accordance with environmental temperature. CONSTITUTION:A platen 200 is composed of a resistance layer 301, a base layer 30a and an ink layer 303. A head unit 100 rotates in an arrow direction A around a head support shaft 20 in response to the movement of a head positioning cam 500 in an arrow direction B. The head positioning cam 500 can change the angle(alpha) of a recording electrode 11 in contact with the resistance layer 301 from 20 deg. to 50 deg.. The smaller contact angle(alpha), the larger contact area of the recording electrode 11 with the resistant layer 301 and also the lower interelectrode resistance value. This is because the platen 200, recording paper 400 and ink film 300 are elastic. In addition, required printing energy can be obtained by changing the contact angle(alpha) in accordance with the environmental temperature, without changing a voltage applied to the printing head and a pulse width according to the environmental temperature.
