Title: Control signal detecting circuit of induction heater device
Inventor: NAGAFUNE TADAYOSHI
IPC: H05B6/06
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To perform a stable automatic frequency control operation by masking detecting output in the other direction when one of the direction from positive to negative and its inverse direction is used for detection in which an electric current crosses zero in an electric current zero crossing circuit. SOLUTION: A high frequency current (i) flowing to a bus bar 2 is detected by a current transformer 3, and is inputted to a comparator 4 through a filter circuit or the like of a high frequency noise after being converted into voltage by a resistor R1. When the electric current (i) changes to positive from negative, an output level of the comparator 4 reverses to H from L, and its rise is triggered by a monostable multivibrator 5, and a pulse (eo ) having a prescribed width is outputted. The output (eo ) is inputted to one of a mask circuit 10 composed of a gate circuit, and a wave reshaped signal on which a voltage waveform (e) is reshaped by a nonlinear element and a resistor potential divider circuit or the like, is inputted to the other. Therefore, the pulse (eo ) generated at time ought not to be originally generated is masked, and does not appear on output of the circuit 10.  The circuit 10 is formed of a NAND gate or an AND gate.

Abstract: PURPOSE:To prevent the MR element of a thin film type magnetic head having a yoke from making Barkhausen noise by providing a laminated structure of Ni-Fe/SiO or SiO2/Ni-Fe to the MR element. CONSTITUTION:When sense current is supplied to thin Ni-Fe film 16 as the 1st layer and a thin Ni-Fe film 18 as the 2nd layer in a direction of an axis of easy magnetization shown by an arrow S, that is, in the direction of parallel arrows M3, M4, a bias magnetic field J4 acts on the 2nd layer by the sense current M3 in the 1st layer, and a bias magnetic filed J3 acts on the 1st layer by the sense current M4 in the 2nd layer.

Title: Tunnel element, driving method therefor and transistor circuit
Inventor: KAWAURA HISAO
IPC: H01L29/786
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a multifunction tunnel element having a high operational margin with low power consumption, a driving method thereof, and a transistor circuit. SOLUTION: When a positive voltage is applied to a first gate 104 and a negative voltage is applied to a second gate 105, a PN junction is formed at the joint of channels 109, 110 induced in the surface of a semiconductor substrate directly under the gates. When the gate voltage is increased sufficiently, carrier concentration in the channels 109, 110 is increased and since the carrier profile thereof is steep, the PN junction can be regarded electrically as a tunnel junction exhibiting negative resistance characteristics at the time of forward bias. Since a tunnel function is formed of electrically induced channels 109, 110, damage can be avoided at the time of introducing the impurities as compared with a conventional tunnel element formed by an impurity layer.
