IPC: H03D3/14
Filed: 1983-02-17
Abstract: PURPOSE:To transmit a signal FM-modulated with fidelity by applying a demodulated output signal to a terminal of a diode, connecting the other terminal to a power supply and connecting a base of a transistor (TR) flowing nearly identical current to one terminal of the diode. CONSTITUTION:Since one terminal of a diode 50 is connected to collectors of TRs 2, 4 and the other terminal is connected to the power supply, currents + or -DELTAi proportional to a modulating signal DELTAf are produced in addition to a DC current (i) as currents flowing to the diode 50. Further, a base of a TR51 is connected to the cathode of the diode 50 and a current identical to that of the diode 50 flows to the emitter of the TR51. A voltage of a demodulating output signal at a terminal (a) is independent of a DC voltage level of an FM demodulating circuit of the pre-stage.

Title: Optical induction magnetic laminated film, optical sensor, optical actuator, magneto-optic recording medium and optical induction magnetic apparatus
Inventor: INOMATA KOICHIRO
IPC: H01F10/32
Filed: 1994-02-24
Abstract: PURPOSE:To selectively change only a magnetizing direction of a first magnetic material layer by inducing an exchange interaction between both the first layer and a second magnetic material layer having larger coercive force than that of the first layer for a laminated film having the first and second layers and a semiconductor layer interposed between both the first and second layers by a light emission. CONSTITUTION:A magnetic material layer 3 of a laminated unit 4 in which a magnetic material layer 2 and the layer 3 are laminated via a semiconductor layer 1 has higher coercive force than that of the layer 2, and an inversion of a magnetic spin scarcely occurs. Both the layers 2, 3 are formed as surface perpendicular magnetization films, no magnetic interaction exists between both the layers 2 and 3, and magnetic spins are aligned upward. When a light hmu corresponding to a band gap of the semiconductor layer is applied to this laminate 4, an exchange interaction is excited between the layers 2 and 3, an antiferro-magnetic coupling occurs, and the spin of the layer 2 is inverted. Thus, the magnetizing direction of a specific magnetic layer can be controlled, and record information can be held even after a light emission.

Title: Semiconductor device
Inventor: SHIGETA YOSHIHIRO
IPC: H01L29/06
Filed: 1984-02-14
Abstract: PURPOSE:To eliminate a shortcircuit even if leads connected with a pad are contacted with the outer edge of a semiconductor chip by allowing a low impurity density reverse conductive type semiconductor layer to remain in contact with a peripheral edge near a bonding pad. CONSTITUTION:A reverse conductive type low impurity density region 26 to a semiconductor substrate is allowed to remain in contact with the peripheral edge near a bonding pad 3 of a semiconductor chip 1. This region 26 is formed at the position contacted with the outer edge of the side formed in parallel with the pad 3. Thus, even if leads 5 connected with the pad 3 of the chip 1 is contacted with an n type layer 26 at the outer edge of the chip, the withstand voltage of a p-n junction to the substrate 11 is high since the impurity density of the layer 26 is low. In other words, a leakage current flowed to the chip is much reduced as compared with the conventional structure in case that a positive voltage is applied to the substrate 11 at the outer edge of the chip 1. Since the substrate 11 of such an integrated circuit is always disposed at the lowest potential, a danger of flowing a shortcircuiting current with the region of the element in the chip by the contact with the leads 5 is eliminated.
