Title: Address space expanding system for microprocessor
Inventor: HATAKEYAMA OSAMU
IPC: G06F12/06
Filed: 1987-10-28
Abstract: PURPOSE:To expand the address space of a microprocessor by converting a real address consisting of 20 bits into a real address consisting of (16+n) bits at every access to a memory. CONSTITUTION:When the same value as a value set up in respective segment registers is set up in external registers corresponding to respective segment registers and 2-stage FIFO buffers connected to respective external registers at the time of resetting the microprocessor, the same value is set up in a corresponding register at every change in the values of respective segment registers during the operation of a program. Thereby, the same value as that of the segment registers is always stored in the heads of the 2-stage FIFO buffers connected to the external registers corresponding to respective segment registers and address conversion is executed by using the value and the address of 20 bits outputted from an address bus to expand the address of the 20 bits into the address space of 24 bits.

Abstract: PURPOSE:To easily widen the range of linear operation with respect to an input signal voltage by providing a voltage controlled current source comprising a 1st differential amplifier circuit and a 2nd differential amplifier circuit taking the output of the 1st differential amplifier circuit as a differential input. CONSTITUTION:A 1st differential amplifier circuit consists of transistors(TRs) 2, 5 and a 2nd differential amplifier circuit consists of TRs 18, 19. When an input signal voltage is applied from at least 1st and 2nd signal input terminals 1, 13, an output signal is extracted from a voltage controlled current source 8 and a prescribed quantity of the output signal is fed back to the 1st differential amplifier circuit of the voltage controlled current source 8 via a feedback circuit 12 to obtain a prescribed filter characteristic. When a current flowing to the 2nd differential amplifier circuit is changed, the transfer conductance of the 2nd differential amplifier circuit is changed and simultaneously the transfer conductance of the 2nd differential amplifier circuit is varied to obtain the variable characteristic of the cut-off frequency. Thus, the linear operating range with respect to the input signal voltage is easily widened.

Title: Semiconductor laser diode
Inventor: YOO TEE KIYUN
IPC: H01S5/343
Filed: 1993-11-02
Abstract: PURPOSE: To minimize optical gain by a method wherein a composition which changes constituent composition is given to an active layer, and the distribution of electrons and positive holes is concentrated in the center of the active layer. CONSTITUTION: In the semiconductor laser diode using a double heteropolar junction structure DH or a quantum well structure QW as an active layer 4, an active layer 4 is composed of an active layer in which constituent composition changed. A compositional ingredient having a small band gap is formed in the center of the active layer 4 to be used for the semiconductor diode. When a compositional ingredient, having a large band gap, is formed on the boundary surface between the active layer 4 and clad layers 3 and 5, the distribution of the electrons and the positive hole in the active layer 4, is concentrated in the center of the active layer 4 by the band gap distribution potential due to the change in composition. Accordingly, even when external voltage is applied, the decrease in optical gain can be prevented by the change in compositional ingredient of the active layer.

Filed: 1991-10-23
Abstract: PURPOSE:To perform a stable loading action even when a driving load is large by a method wherein a guide-post base is driven by using a second guide-post drive means according to the movement position or the movement speed of a first guide-post base drive means. CONSTITUTION:When a cassette base stand is slid, link gears 242, 250 are turned. When the gear 250 is turned, a link A 252 is turned and driven. However, since a guide van is arranged on a fixed chassis, an impulsive load becomes easily large. As a result, a loading action cannot be performed after that or a magnetic tape is damaged. In order to prevent this, a bent part 2h is formed at a chassis, and the link A 252 is brought into contact with the bent part. Thereby, the link A 252 is turned in a direction opposite to the direction of A, a second drive means can be actuated and guide post bases 246, 258, 259 can be driven.
