Title: Equivalent testing device for breaker
Inventor: SATO MINORU
IPC: G01R31/327
Filed: 1987-09-09
Abstract: PURPOSE:To expand a test voltage range up to a double voltage only by changing connections of existent facilities by connecting a circuit which consists of a transformer and a capacitor and where a leading current flows to the terminal of the breaker to be tested, and making the polarity of a voltage opposite. CONSTITUTION:When a power generator 1 applies a prescribed voltage to transformers 9 and 10 with a turning-on switch 2, a current (i) flows to the breaker 7 through capacitors 11 and 12 in the presence of secondary voltages ea and eb while the breaker 7 to be tested is closed. In this state, when the current (i) is cut off by supplying a disconnection instruction to the breaker 7, ground voltages Va and Vb with the completely opposite polarities are applied to the terminals of the breakers 7 right after the disconnection. Therefore, the sum voltage of output voltage effective values of the transformers 9 and 10 is applied between the terminals of the breaker 7 and the range of the test voltage is widened.

Title: Lens collision preventing mechanism
Inventor: YOSHIDA SETSUO
IPC: G03B17/12
Filed: 1989-08-30
Abstract: PURPOSE:To prevent a power variation system lens and an image formation system lens from colliding against each other by making so as to interfere part of an extender switching lever with part of a macroring on a zoom lens which has an extender power varying mechanism and makes a close-up macrophotography by the movement of an image formation system lens group. CONSTITUTION:In macrophotographic use, the macroring 2 is rotated, so an uncut part comes to the position of the sectorial projection of the extender switching lever 1 according to the shape of a cut 7. At this time, when the extender switching lever 1 is operated, the sectorial projection collides against the outer periphery of the macroring 2, so the extender switching lever 1 can not be operated. Then when an extender is used, the extender switching lever 1 enters the cut part 7 of the macroring 2, which can not be rotated. Consequently, the power variation system lens and image formation system lens are prevented from colliding against each other.

Inventor: KAMATA HISAHIRO
IPC: H02M7/217
Filed: 1995-09-01
Abstract: PURPOSE: To improve the power factor of the AC power inputted into a diode bridge with a simple circuit configuration. CONSTITUTION: The full wave of the AC voltage from an AC power source 1 is rectified by a diode bridge 2, and the rectified output is applied to the primary winding Np while a switching element 4 is on. The voltage induced to the secondary winding Ns is rectified and smoothed by a rectifier and smoothing circuit 16 to output DC output voltage Vout. When the switching element 2 is off, the energy accumulated in the inductor 13 of the rectifier and smoothing circuit 16 is taken out from the primary chalk winding NLp to change a capacitor C2 of large capacitance through a rectifier circuit (diode D1) and, when the voltage becomes a prescribed one, apply it to the primary winding Np of a transformer 3 through the second diode D2 together with the output of the diode bridge 2.  As a result, the outputted current of the diode bridge 2 runs through the period of a valley in pulsating current, and AC current runs around zero of AC voltage, thus improving power factor.

Abstract: PURPOSE:To obtain an acoustic signal with high clearness corresponding to the hearing characteristic of a person, who has difficulty in hearing, by dividing an electric signal from an input part into plural frequency bands and changing the amplification factor of a correspondent amplifier corresponding to the levels of these divided electric signals. CONSTITUTION:The acoustic signal converted to the electric signal by a microphone 1 is divided into respective channels corresponding to the respective frequency bands by band filters 2-4.

At such a time, for example, a CH1 control part 5 compares the output of the band filter 2 with a reference signal IP 1 and outputs a control signal 21 for changing the amplification factor of the amplifier 8. The signals amplified by the respective amplifiers 8-10 are synthesized by a synthesizer part 11 and according to this synthesized electric signal, a speaker 12 is driven. Thus, the distortion or noise of hearing aid is eliminated, and the acoustic signal with high clearness can be obtained corresponding to the hearing characteristic of the person who has difficulty in hearing.
