Patent JP-H0239714-A (JP)
Title: Central frequency and attenuation variable type notch filter
Inventor: TOYODA YUKIHIRO
IPC: H03H7/07
Filed: 1988-07-29
Abstract: PURPOSE:To independently, simultaneously at high speed control a tuning frequency and an attenuating quantity by using at least one variable capacity such as a varactor diode for a capacitance and using a transistor as a resistance element. CONSTITUTION:A turning frequency is changed by adding a frequency and changing the bias of a varactor diode VD1 and the attenuating quantity is changed by adding the attenuating quantity control signal and changing the bias of a transistor Q1. Thus, the present notch filter can be effectively used as an image removing filter at frequency high speed variable system since the tuning frequency can be made variable at high speed. The filter is useful as the filter used to the interruption frequency detecting and interruption wave removing system.

Title: Vacuum cleaner
Inventor: KODACHI TORU
IPC: A47L9/08
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a vacuum cleaner capable of exhibiting a sufficient dust- collecting capability even with a small suction motor. SOLUTION: An exhaust part 7 and a suction part 8 are formed inside a suction port 17 and exhaust air 9 released from the exhaust part 7 is made to beat a floor face and circulate into the suction part 8. Thereby dust on a floor face is blown up and more easily collected in a dust-collecting chamber 2. Also, the dust and air migrate over an almost horizontal surface near the floor face and are not obstructed by gravity. Therefore, dust of a relatively large mass can be trapped in the dust-collecting chamber 2 without requiring a suction motor 4 of a large suction force.

Title: Lighting device for high pressure discharge lamp
Inventor: KITADE WATARU
IPC: H05B41/24
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To avoid an acoustic resonance phenomenon and to keep stable lighting by oscillating two high and low frequencies with an oscillating part and always alternately switching the two frequencies with a frequency switching part. SOLUTION: When output of an oscillator, a rectangular wave oscillator for example, is high, a photocoupler is made conductive, a resistor R is connected in parallel to a resistor RT, and an oscillator RC oscillates high frequency. When output of the rectangular wave oscillator is low, the photocoupler is shut off, and the oscillator RC oscillates low frequency depending on only the resistor RT and a capacitor CT. By this switching, after a high pressure discharge lamp is lit at high frequency for a constant time, it is lit at low frequency for a constant time, and this lighting is repeated to stably light. Changing time of high frequency and that of low frequency or its ratio has an effect on preventing an acoustic resonance phenomenon.
