Title: Photodetector
Inventor: SHIMIZU AKIRA
IPC: G01J1/02
Filed: 1990-02-26
Abstract: PURPOSE:To obtain a photodetector having little light absorption by making the photon energy and a subband spacing very much larger than the LO phonon energy or by setting the absolute value of a difference between the photon energy and the subband spacing at an appropriate one. CONSTITUTION:The thickness and other conditions of the quantum well structure QWS (N) at the center and the quantum line structure QLS (w1, W2) on both ends are adjusted in advance so that the electron level or quantum level of a subband may have the specified relations with each other. To avoid light absorption, it is necessary that the subband structure and the photon energy have the specified relations with each other. Besides, the doping amount in the QWS is given adjustments for electrons to occupy a base subband only. An LO phonon has the largest oscillation energy among various phonons including a transverse wave phonon and longitudinal wave phonon of an acoustic mode. Consequently, light absorption by phonon can be kept down to the negligible level by making the photon energy and a subband spacing larger than the LO phonon energy.

Title: Video signal processing device
Inventor: MIHASHI YASUO
IPC: H04N5/208
Filed: 1988-02-26
Abstract: PURPOSE:To improve S/N and the sharpness of pictures by providing a specific noise canceller circuit and a signal processing circuit. CONSTITUTION:The noise component in a flat picture part is eliminated from a video signal (a) including a noise component (n) by a low pass filter 11 of a noise canceller circuit 25 to obtain a signal (h), and a difference signal component (i) is obtained by a subtracting circuit 12. A signal from a limiter 13 is subtracted from the signal (i) by a subtracting circuit 14 to obtain a difference signal component (k) which scarcely includes noise, and the signal (h) is added by an adding circuit 15 to obtain a video signal l where most of the noise component of the signal (a) is eliminated. The signal l passes delay circuits 16 and 17 of a signal processing circuit 26 to become signal (n), and this signal is added to the signal l by an adding circuit 18, and a signal (p) having a half amplitude is obtained through a 1/2 attenuator 19. A signal (q) obtained by subtracting the signal (p) from a signal (m) from the circuit 16 in a subtracting circuit 20 is reduced by an attenuator 21. This signal is added to the signal (m) by an adding circuit 22 to obtain a signal (r). Thus, S/N and the sharpness are improved.

IPC: H04L12/70
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a communication protocol managing method with which the protocol management of a network is not concentrated in one station. SOLUTION: Concerning the network with which plural exchanges are connected and packets are transmitted/received between the exchanges on the basis of prescribed protocol information, prescribed protocol information is uniquely related to an identifier. When any exchange receives a connection demand (step S1), it is investigated whether the exchange has the requested protocol information or not (step S2). When that exchange does not have the protocol information, it is investigated whether any other exchange has the protocol information or not (step S4) and when other exchanges do not have the protocol information, the protocol information is requested to the connection requested terminal (step S7). When an exchange acquires the protocol information by any method, the acquired protocol information is reported to other exchanges as well (step S11).

The resin 2 used at this time is the resin 2 having the refractive index after curing higher than the refractive index of the optical fiber 1. Any of the resin of a thermally curing type, UV curing type or oxygen curing type is usable. As a result, the end treatment of the small return light quantity is easily executed and the structure of the non-reflection treated part is made smaller.
