Title: Waveguide path type optical receiver of quantum well base of semiconductor material for coherent communication system having especially multiple polarization
Inventor: KURISUTOFU MINO
IPC: H01S5/00
Filed: 1993-03-23
Abstract: PURPOSE: To simplify a polarization control system by providing a 2nd optical detector for absorbing a crossing-directional electric component of light which is hardly absorbed by a 1st optical detector. CONSTITUTION: This receiver has a 1st optical detector 10, having completely dichroic waveguide structure that preferentially absorbs the crossing-directional magnetic component of an incident light 16 and a 2nd optical detector 22, which is identical with the optical detector 10 and arranged right behind the optical detector 10, so as to secure the optical coupling of multilayered strips. Those two optical detectors 10 and 22 are hybrid circuits, and the multilayered surface of the optical detector 22 crosses the multilayered surface of the optical detector 10 at right angles. Therefore, the crossing-directional electric component TE of the incident light 16, which is perpendicular to the TM and exits from the optical detector 10 becomes perpendicular to the multilayered surface of the optical detector 22 and is preferentially absorbed by the optical detector 22.  Consequently, the polarization control system can be simplified, which is used for a coherent communication system.

Title: Music sound synthesizer
Inventor: KOMANO TAKASHI
IPC: G10H1/02
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To reduce tone color creating cost and to achieve the compatibility among tone color products by using common values as the tone color parameters given to the processing device. SOLUTION: This synthesizer is equipped with a tone generating section 107 which has a small scale constitution. Tone color parameters are then given to the section 107. For the case of a small scale constitution, the synthesizer switches first and second modes in accordance with the mode switching operation of a setting/displaying section 106. The music sound synthesis algorithms, which are to be executed, are switched by the mode switching. Note that even for a small scale constitution, the tone color parameters prepared for every tone color are stored in a ROM 102 with the memory map which is same as the tone color parameter sets for a large scale constitution. Since these parameters are the parameters which fundamentally rule the tone colors, these parameters are commonly used regardless of the scales and the modes of the device.

Title: Programmable counter
Inventor: SHIN YASUHIRO
IPC: H03K23/00
Filed: 1982-04-21
Abstract: PURPOSE:To obtain a maximum operation frequency for any program value, by inhibiting a read of a specific code detection signal in a section wherein a preset signal is generated. CONSTITUTION:In response to an input signal fIN, FFs f1-f8 count down and when an NOR gate 9 detects an output code being 4, the output of the gate G9 goes up to H. Its detection signal is delayed by shift registers S1-S3 to obtain the preset signal Y2, which is inputted to the reset input terminal R of the register S1. The register S1 does not read a signal inputted to an input terminal D9 while a level H is applied to the terminal R, and fixes the output terminal -09 at a level L. Consequently, even when preset data is 132, the register S1 does not read it even in case of a 4-detection error due to the H-level transfer delay of the most significant digit bit, so the data 132 is preset in the FFs f1-f8 normally, improving the highest operation frequency of the signal fIN.
