Title: Method of driving bistable semiconductor laser
Inventor: ISHIKAWA MAKOTO
IPC: G02F3/02
Filed: 1988-11-18
Abstract: PURPOSE:To obtain a large modulation optical output without a driver circuit by a method wherein an impressed voltage in an absorption region of a bistable semiconductor laser is changed. CONSTITUTION:A bistable semiconductor laser 1 is provided with an excitation region 2 and an absorption region 3; when an electric current I is injected only into the excitation region 2, an optical output is increased nonlinearly at a certain electric current value. These oscillation threshold values I1, I2 are changed in accordance with an optical loss in the absorption region 3; the oscillation threshold values are increased with an increase in the optical loss. The optical loss in the absorption region 3 can be controlled easily by a very weak voltage which is lower than a voltage causing a gain; the optical loss is increased with a decrease in impressed voltages V1, V2. Accordingly, only when a very weak signal voltage 4 is applied to the absorption region 3 in a state that a proper definite bias current IB has been applied to the excitation region 2, it is possible to obtain a large modulation optical output 6. Thereby, it is possible to obtain the large modulation optical output without a driver circuit and only by changing an impressed voltage in the absorption region.

Abstract: PROBLEM TO BE SOLVED: To obtain a data storage format for a carrier capable of efficiently using the bit capacity of a software carrier by dividing a bit stream among data blocks so as to obtain a bit as occasions demand to appropriately reconstruct respective signals represented all the times after the bit of each bit stream is buffered by a reproducing device. SOLUTION: In an optical disk 23, each signal is represented by a bit stream designed so as to be processed at a prescribed changing speed. Plural signal bit use rates are mutually independent, digital data on the optical disk 23 are formed as a series of data blocks, and a data block includes a bit of a different number in a multi-bit stream. And, the bit of each bit stream is read from the optical disk 23 and is buffered by an interchangeable reproducing device, and then, the bit stream is divided among data blocks so as to obtain it as occasions demand to appropriately reconstruct respective signals represented all the times.

Title: Carrier tape
Inventor: KOBAYASHI MASAHIRO
IPC: B65D85/38
Filed: 1988-11-17
Abstract: PURPOSE:To eliminate the falling off of a circuit part and at the same time, remove the circuit part easily by a method wherein at the adhesive film region on a carrier tape which has sprocket holes on the both sides and an adhesive film region on which a circuit part is bonded at the intermediate part, an adhesive which is enbrittled by curing by ultraviolet ray is applied. CONSTITUTION:For a carrier tape, on a guide tape 2, on which sprocket holes are provided on the both sides, an adhesive 4 which lets ultraviolet ray permeate, e.g., an acrylic resin adhesive with a low polymerization degree, is applied. On this adhesive 4, an intermediate tape 5 which becomes a barrier layer for the adhesive 4 and also lets ultraviolet ray permeate, e.g., a tape made of a polyester resin, is glued. Further, on this intermediate tape 5, an adhesive 6 which absorbs ultraviolet ray, e.g., a polyester resin adhesive, is applied. And the carrier tape, for which circuit parts 3 are bonded on the intermediate tape 5, is wound on a reel. When this circuit part 3 is actually installed on a print circuit base board, ultraviolet ray 8 is irradiated from the rear surface of the guide tape 2, and the adhesive 6 is enbrittled by curing. By doing this, the adhesive power of the adhesive 6 is reduced, and the circuit part 3 can be easily removed.

Title: Video tape recorder
Inventor: OKURA JIRO
IPC: H04B1/62
Filed: 1993-11-22
Abstract: PURPOSE:To eliminate the distortions of reproduced video signals by adding a variable time constant means to a de-emphasizing means and controlling the variable time constant means based on the output signal of the de-emphasizing means. CONSTITUTION:The composite video signal which is de-emphasized by a de-emphasizing circuit 12 is inputted to a gate circuit 14. The circuit 14 is operated only in a horizontal blanking period by a control signal, and therefore a horizontal blanking signal is inputted to an A/D converter 16 and converted into a digital signal. This digital signal is inputted to a microcomputer 18 and undergoes a prescribed processing. Then a prescribed control voltage signal is outputted from the microcomputer 18 and inputted to a variable capacity diode 22 through a D/A converter 20. Thus a variable time constant means contained in a de-emphasizing means is controlled by the diode 22 and the resistances R1 and R2. Therefore the reproduced composite video signal never includes the distortions.

IPC: G02F1/01
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To provide an optical switch which changes over an incoming light signal to one of plural outputs in a transient optical communication system. SOLUTION: Plural glass waveguides GWL1,...GWL4 are constituted within a first plane. At least one polymer waveguide PWLA having an acute angle with these glass waveguides is constituted within the plane superposed on an upper side. A vertical direction coupling region is formed where the polymer waveguide described above intersects with the glass waveguides constituted on the lower side. The coupling characteristics may be selectively influenced by using heating electrodes EA1,...EA4; EB1,...EB4. The changing over of the light from the one glass waveguide to another glass waveguide is effected by coupling of the light set at the temperature of the vertical direction coupling region from the glass waveguide to above the polymer waveguide in which the light is introduced and is downwardly coupled into the desired glass waveguide within another coupling region.
