Abstract: PURPOSE:To obtain a recording medium which is stable for a long period of time and has excellent recording and reproducing characteristics by adding one or >=two kinds of elements among Au, Ag, Pt, and Pd to an alloy of Nd and iron family element. CONSTITUTION:M in the compsn. formula NdalphaMbetaNgamma of the alloy contg. neodium Nd is one or >=two kinds of Fe and Co, and N is one or >=two kinds of elements among Au, Ag, Pt, and Pd. A thin amorphous alloy film having the compsn. range expressed by 16<=alpha<=30, 60<=beta<=84, 0.5<=gamma<=10, alpha+beta+gamma=100 is then formed. The magneto-optical recording medium having the less deterioration with lapse of time, excellent long-term stability and excellent recording and reproducing characteristics is thereby obtd. Namely, the relation between the amt. of addition and Kerr rotating angle when Au, Ag, Pt, and Pd are added to the NdFe alloy is such that the Kerr rotating angle increases when Au, Ag, Pt, and Pd are added thereto. The effect appears up to about 10% amt. of addition and is particularly high when Pt and Au are added to the alloy.

Title: Proximity switch
Inventor: MAKABE HIDEKAZU
IPC: H01H36/00
Filed: 1985-02-14
Abstract: PURPOSE:To detect surely passing of a heater by utilizing the change in the magnetic property of a thin film heat sensing magnetic substance due to temperature. CONSTITUTION:When a heater approaches a proximity switch 3, the temperature of the thin film heat sensing magnetic substance 4 of the proximity switch 3 rises and reaches a temperature T2 higher than the Curie temperature T0 from a temperature T1. Then the magnetism of the magnetic substance 4 is lost and the property is changed from ferromagnetism into paramagnetism. Thus, an output voltage of an oscillator 6 is applied a load resistor 7 only, a Schmitt trigger circuit 8 inverts into the ON-state and outputs a signal corresponding thereto to a signal line 11. When the heater is parted from the proximity switch 3, the temperature of the thin film heat sensing magnetic substance 4 falls down from the temperature T2 and returns to the temperature T1. Then all restores to the original state.

Title: Low-distorsion amplifier output stage for analog/digital converter
Inventor: JIEFURII UIRIAMU SUKOTSUTO
IPC: H03H19/00
Filed: 1992-01-16
Abstract: PURPOSE: To obtain a low-distortion output part for a digital-to-analog converter(DAC) which uses a switched capacitor filter for an analog part. CONSTITUTION: The output stage of the DAC is used in combination with the switched capacitor filter to drive a low-impedance load. A 1st current source is composed of a transistor(TR) 284 and supplies a current to a load resistance 264 at the time of positive output voltage variation. A 2nd current source is composed of a TR 286 and sinks a current from the load resistance when voltage variation is small. The TR 284 performs class-AB operation. When the gate voltage of the TR 284 rises, the current flowing to the TR decreases and the current flowing to TRs 286 and 292 in mirror image relation with a TR 288 increases to sink the load current. The TRs 284 and 286 supply a load current irrelevant to the drain current of a TR 266 to the load resistance.
