Title: Electrolytic production of ferromagnetic superfine powder
Inventor: KATO NOBUAKI
IPC: B22F9/30
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To efficiently produce a ferromagnetic superfine powder with very simple facilities by using an aq. soln. of sulfate or acetate of Fe, Co or Mn or a mixed aq. soln. of such sulfates or acetate as an electrolytic soln., forming a pair of electrodes with an Al material and an insoluble electrode material and controlling AC supplied between the electrodes. SOLUTION: An aq. soln. of sulfate or acetate of Fe, Co or Mn having 4-12 wt.% concn. or a mixed aq. soln. of such sulfates or acetate having 4-12 wt.% concn. is used as an electrolytic soln. A pair of electrodes are formed with an Al material and an insoluble electrode material such as graphite or platinum. When AC is supplied between the electrodes while controlling voltage, bubbles are generated on the surfaces of the electrodes and simultaneously a black fine powder is generated on the surface of the Al electrode and near the surface. The powder settles gradually while suspending along a flow of bubbles and the settled powder is recovered with a magnet.

Title: Standard system converting device
Inventor: USAMI AKIRA
IPC: H04N7/00
Filed: 1989-09-22
Abstract: PURPOSE:To always output a desired video signal even when the standard system of an input signal is changed by arbitrarily selecting an output system and controlling a system converting circuit according to the input signal. CONSTITUTION:A system discriminating circuit 3 executes discrimination by measuring the vertical synchronizing signal cycle of the input signal and applies a discriminated result to a system converting circuit 2, inverted gate 4 and exclusive OR gate 6. The system converting circuit 2 inputs the discriminated result as an input system and inputs the output of the inverted gate 4 as the output system. Then, the signal inputted from an output system select signal terminal 5 is applied to the exclusive OR gate 6 and the output of the gate 6 is applied to a switch 7. The switch 7 is changed over so as to output the input signal of the system converting circuit 2 when the discriminated result is same as a select signal, and to output an output signal from a signal output terminal 8 when the discriminated result is different from the input signal. Thus, even when the input signal system is changed, the video signal can always be outputted by the single system.

Title: Low frequency amplifier and control device for amplifier
Inventor: YASUDA TADAO
IPC: G10K15/04
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To automatically control sound volume of an acoustic instrument to a sound volume that does not disturb when calling or transmission of a portable telephone is performed during driving an automobile, by detecting radio transmitted from the portable telephone, outputting a detection signal, and controlling an operation of an amplifying means based on this detection signal. SOLUTION: A radio detecting means 61 detects radio transmitted from a portable telephone and outputs a detection signal. A control means 62 controls ON or OFF of a power supply circuit based on the detection signal. An output connector 64 outputs power supply from an on-vehicle battery to a car stereo or a booster amplifier via the control means 62. In this structure, when the radio transmitted from the portable telephone is detected, power supply to the car stereo or the booster amplifier is blocked to prevent sound from coming through a speaker. When a communication finishes and no radio is transmitted from the portable telephone, power supply to the car stereo or the booster amplifier is started again to send sound through the speaker.

Abstract: PURPOSE:To restrain an air-fuel ratio from shifting to the lean side as well as to abate an amount of harmful ingredient discharge in exhaust gases by compensating an air-fuel ratio feedback control constant to the overrich side at a time when a down-stream side air-fuel ratio detecting means is in a nonactivity. CONSTITUTION:Respective means M3, M4 detecting an air-fuel ratio each are set up in both upper and lower parts of catalytic converter rhodium M2 set up in an exhaust passage of an internal combustion engine M1. When a fact that a driving state of this engine M1 is a specified state is judged by a means M5, an air-fuel ratio feedback control constant is calculated by a means 6 on the basis of the detected result of the means M4. Likewise, according to the calculated constant, an air-fuel ratio controlled variable is calculated by a means M7 on the basis of the detected result of the means M3. In addition, an air-fuel ratio is adjusted by a means M8 according to this calculated controlled variable. In this case, when it is so judged that the means M4 is in a nonactivity by the means M5, the control constant being used at the means M7 is compensated to the overrich side by a means M9.
