Inventor: MAIKERU RII MIRAADO
IPC: C04B41/45
Filed: 1990-11-06
Abstract: PURPOSE: To form a metal oxide barrier coating layer having a preselected coating microstructure and thickness by applying a metal salt so as to form a metal oxide to reinforcing fibers, treating the coating layer at a high temperature and improving the interface between the reinforcing fibers and a matrix. CONSTITUTION: A solution prepared by adding a methocellulose compound, etc., as a binder to an aqueous solution of a metal salt so as to decompose at high temperatures and form a metal oxide without causing a toxic chemical reaction with reinforcing fibers, preferably a zirconium oxyhalide or a hafnium oxyhalide is applied to sapphire fibers (e.g. Al2 O3 fibers) as the reinforcing fibers in, e.g. a ceramic matrix composite material and the resultant reinforcing fibers are then heated at a temperature (600 deg.C) decomposing the metal salt to form a barrier coating layer of the metal oxide having a preselected microstructure and a thickness of about 0.05 to <7% based on the fiber diameter. When the concentration of the metal salt in the aqueous solution is 1 to <15 wt.%, a fine and microcrystalline oxide is obtained.  When the concentration is >=15 wt.%, a coating having a crystalline microstructure is obtained.

CONSTITUTION:An active region 15 is composed of quantum well semiconductors different from each other number of layers or thickness or both in number of layers and thickness. A large primary modulation can be realized through a very small light absorption loss modulation taking advantage of the gain saturation characteristics of an active layer 2. At this point, a modulation action is accompanied with the modulation of the active layer 2 in carrier density, but a chirp width is made smaller than that of a conventional distributed feedback-type semiconductor laser or a reflection-type semiconductor laser. Furthermore, a comparatively large carrier density modulation can be executed attendant on a very small light absorption loss modulation, a FM characteristic is predominant through a wide range of a frequency by a carrier effect, so that flat FM characteristics can be obtained. By this setup, a single-wavelength semiconductor laser, which is able to execute a single-wavelength operation low in chirp, flat in FM modulation characteristics, and effectively applicable to a coherent system and the like, can be obtained.

IPC: G05F1/70
Filed: 1987-11-30
Abstract: PURPOSE:To surely detect overcurrent by means of a simple circuit by monitoring a voltage between the anode and cathode of thyristors and deciding a current supply time. CONSTITUTION:A voltage detector 101 for detecting the voltage between the anode and cathode of the thyristors is connected between both the ends of the thyristors 6, 7 to receive a voltage signal and transfer the signal to a level detector 102.
