Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser having high performance by reducing a strain of an active quantum well layer under the condition of sufficiently ensuring an electron and hole confinement energy of a long wave length band semiconductor laser. SOLUTION: An active layer 7 is made to have a quantum well structure, a nitrogen system V group mixed crystal semiconductor such as GaInNAs is used for a well layer 6, and a semiconductor of stretching strain for barrier layers (light guide layers) 4 and 5. GaNAs or GaNPAs is preferable for the semiconductor having stretching strain. Electron and positive hole confinement energy can be sufficiently ensured by using the nitrogen based V group mixed crystal semiconductor for both the well layer 6 and the barrier layers 4 and 5. Also each layer's strain of the quantum well active layer and the total strain can be simultaneously reduced by stress compensation by the well layer 6 and the barrier layers 4 and 5. By this means a semiconductor laser having a high performance can be provided.

Title: Musical sound generating method
Inventor: TAMURA GENICHI
IPC: G10H1/00
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To make inputs not affect the number of sound generations in a waveform processing even when MIDI(musical instrument digital interface) inputs are concentrated. SOLUTION: The sound source driver processing of concentratedly inputted MIDI inputs M1 to M3 is dispersedly performed in processings of seven times of processings (a) to (g) and generated sound source parameters are stored in a P buffer (sound source parameter area). Then, it becomes a sound generating timing, musical sound waveforms are generated as the result of a waveform generating processing B based on the sound source parameters being in the P buffer. Since the sound source driver processing is dispersedly performed, throughputs Jd1 to Jd4 of the processing are never abruptly increased and sufficient throughputs can be assigned to the waveform generating processing.

Title: Liquid crystal display device
Inventor: IKEDA MINORU
IPC: G09G3/36
Filed: 1988-12-02
Abstract: PURPOSE:To use an optical amplifier which is small in rated power consumption by connecting resistances to the outputs of operational amplifiers in series and then connecting smoothing capacitors. CONSTITUTION:Intermediate levels V1', V2'... Vn' are extracted by resistance division between two kinds of power sources VDD and VEE which differ in voltage value and operational amplifiers OP1 - OP4 are connected to the intermediate levels to obtain low-impedance intermediate levels V1, V2... Vn, thereby driving liquid crystal. Then resistances R8 - R11 are connected to the outputs of the operational amplifiers OP1 - OP4 in series and the smoothing capacitors C1 - C4 are connected. Therefore, the output currents of the operational amplifiers R8 - R11 can be limited by the resistances R8 - R11. For variation of a liquid crystal driving power source due to the current limiting resistances R8 - R11, the values of the smoothing capacitors C1 - C4 are increased to stabilize the variation. Consequently, the operational amplifiers which are small in rated power consumption are usable.
