Title: Semiconductor laser array device
Inventor: MATSUI KANEKI
IPC: H01S5/40
Filed: 1985-02-28
Abstract: PURPOSE:To obtain a semiconductor laser array device emitting laser beams having a large output according to a radiant pattern at a single peak by making the reflectivity of the cleavage end surface of an intermediate region between active waveguides larger than that of the resonator end surfaces of the active waveguides. CONSTITUTION:In an index waveguide type semiconductor laser array, the reflectivity of an intermediate region can be made larger than that of an active waveguide section by forming multilayer films on the cleavage plane of the intermediate region. Consequently, resonator mirror loss at a 0 deg. positional mode can be made largely lower than that at a 180 deg.-phase mode, and loss at a 0 deg.-phase mode can be made smaller than the 180 deg.-phase mode, thus making oscillation threshold gains at the 0 deg.-phase mode smaller than the 180 deg.-phase mode. Accordingly, a semiconductor laser array device emitting laser beams synchronizing at a 0 deg.-phase can be realized, and high-output laser beams having one far field pattern up to a high injection region can be acquired.

Title: Fuel feed amount control device
Inventor: SAKAMOTO MASAHIDE
IPC: F02D41/18
Filed: 1985-03-06
Abstract: PURPOSE:To provide a fuel feed amount control device, having high precision at a low cost, by a method wherein signals from a hot wire sensor adapted to detect an intake air flow rate are inputted at intervals of a specified time. CONSTITUTION:In a control circuit 30, signals qa from a hot wire sensor 18 are inputted periodically at intervals of a specified time independently of engine rotation. An integration value, obtained through integration of the aboves throughout a period T of an ignition signal, is divided by the number of times which the signal qa is inputted during the period T to determines a value Qa. The calculated value Qa produces an average means of the output signal qa from the hot wire sensor 18 during the period T serving as an average period to represent a correct intake air amount. This enables an intake air flow rate to be a always measured without using a crank angle sensor independently of the number of revo- lutions of an engine.
