Patent JP-S58198909-A (JP)
Title: Electronic circuit
Inventor: SEKI KUNIO
IPC: H03F3/34
Filed: 1982-05-17
Abstract: PURPOSE:To prevent the breakdowns of a couple of output TRs due to counter electromotive force by providing a couple of output TRs and a couple of protecting diodes, and supplying the counter electromotive force generated by an inductive load to a couple of power sources alternately through said TRs and diodes. CONSTITUTION:A base voltage is supplied to a TRQ1 by a plus input signal to flow the 1st current in the order of +Vcc, the TRQ1, inductive load L0, and ground. When the input signal turns minus, the TRQ1 turns off and at the same time, the base voltage is supplied to a TRQ2. A large current by the counter electromotive force of the load L0 flows in the order of -Vcc, the output TRQ2, and a point A. In this case, a diode D2 allows a current 1/hFE to flow between the collector and base of the TRQ2 when the TRQ2 has a current amplification factor hFE. Therefore, the TRQ2 operates as a reverse TR. When the TRQ2 turns on, on the other hand, the 2nd current reversely in the order of the ground, L0, TRQ2, and -Vcc. If the input turns plus in said state, the TRQ2 turns off again. In this case, a large current flows through the TRQ1 by the counter electromotive force and the diode D1 allows the current 1/hFE to flow to the TRQ1. Namely, almost all of the large current flows to the TRs Q1 and Q2 alternately.

Title: Overcurrent protection circuit
Inventor: YANAGISAWA TAKESHI
IPC: H02M7/21
Filed: 1994-04-20
Abstract: PURPOSE:To prevent an overcurrent by prohibiting a current flow through the load side by stopping a switching regulator connected to a Zener diode when an overcurrent flows through the load side. CONSTITUTION:In the case where the load side is short-circuited in an abnormal state, an overcurrent will flow through a load terminal 10, accordingly, an induced electromotive force of a detecting winding 15 decreases, and the output of a rectifier circuit 16 decreases. Because of this, a current flowing through a Zener diode 17 decreases, a charging and discharging circuit 19 is discharged, a base potential of PNP transistor 23 drops and a transistor 23 turns on, a current flows from the collector of the transistor 23 to the earth through a resistor, a gate potential of a thyristor 22 rises, and the thyristor 22 turns on. In consequence, a voltage of a power supply terminal 14 of an oscillator 13 drops, the oscillation of the oscillator 13 stops, and the switching regulator connected to the Zener diode 17 is stopped.

Title: Method for measuring surface level density distribution of metal-insulator-semiconductor(mis) structure
Inventor: KIMURA MIKIHIRO
IPC: G01R31/26
Filed: 1991-04-15
Abstract: PURPOSE:To enable accurate measurement of the distributed state of the surface level density of a metal-insulator-semiconductor(MIS) structure by finding the ideal CV characteristic of the MIS structure from a surface potential, and comparing the ideal CV characteristic with a measured low frequency or a quasistatic CV characteristic. CONSTITUTION:After a flat band voltage is found through measurement of the high-frequency CV characteristic of an MIS structure, a surface potential is calculated by definite integral processing using a specific equation based on the flat band voltage. Then the ideal CV characteristic of the MIS structure is found from the surface potential and compared with a measured low frequency or a quasistatic CV characteristic so as to measure the distributed state of the surface level density of the MIS structure. Therefore, the flat band voltage of an ideal CV curve coincides with an experimentally found low voltage or the flat band voltage of the quasistatic CV curve and so the surface level density distribution of the MIS structure can be accurately measured.

Title: Control method of air-fuel ratio
Inventor: FUKAYA KATSUYOSHI
IPC: F02D33/00
Filed: 1981-05-30
Abstract: PURPOSE:To perform stable control of air-fuel ratio at opening and closing of a needle valve, by regulating air bleed quantity to an air bleed position through a step motor. CONSTITUTION:A step motor 10 both moves a tapered needle valve 11 axially shuttling by its reversible rotary motion and changes opening area of a main fuel air bleed passage 13 and low speed air bleed passage 14 in a carburetor 12. Even if the needle valve 11 is in a fully closed state, a minimum air bleed amount can be held to prevent fuel from flowing into air bleed passages 13, 14. In this way, air is endlessly flowing in the air bleed passages 13, 14, and fuel is never immersed in the air bleed passages 13, 14 by pulsation of the carburetor, then misinformation is not caused, thus stable control of air-fuel ratio can be performed.

IPC: C22C33/04
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To obtain a raw material powder for magnet excellent in a magnetic property by forming a low heat conduction layer on a roll surface so as to suppress the generation of a fine chill crystal structure in a solidified raw material for magnet when producing a raw material for a R-T-B magnet by a rapid solidifying method by using a cooling roll. SOLUTION: When producing a raw material for a R-T-B magnet, a molten metal of the alloy is rapidly cooled/solidified in an inert gas atmosphere of Ar, etc., or a vacuum with a twin roll method, etc., to be pulverized. In this case, a surface layer of 0.1-10 mm thickness, which is made of a material having a low coefficient of heat conduction of Ni, Cr, alumina, etc., is formed on a surface of a rapid cooling roll, which is made of a material having a good coefficient of heat conduction of Cu, etc. Due to presence of the surface layer, the generation of a fine chill crystal is suppressed to a structure of the R-T-B alloy to be cooled/solidified. By setting its generation rate to <=5%, a magnetic property of the R-T-B magnet, which is obtained by crushing the alloy and forming/sintering, is improved.
