Title: Excess power controller and method therefor
Inventor: TAMURA SHINJI
IPC: H02J3/00
Filed: 1994-03-31
Abstract: PURPOSE:To utilize excess power of a non-utility generator in a time zone of a valley of repeated variable loads by switching the load when a direction of a current does not change within a set time and an integrated electric energy reaches a set level. CONSTITUTION:A direction detector 3 detects a direction of a current according to an input signal from a detecting transformer 2. When a lower power reaches a non-utility generation level from a high load level toward a low load level and a chattering detector varies an input signal from the detector due to a change of a current flow, it decides presence of the chattering. When the input signal from the detector 3 has no change in the umpteenth time zone and a signal of arrival of electric energy from an electric energy detector at a set level is obtained, it outputs a signal of absence of the chattering. A control circuit decides absence of the chattering at this time point, outputs a reverse control signal to a switching unit 5, supplies excess power to an electric facility 6 such as a compressor, etc., and load-operates a motor 7.

Abstract: PURPOSE:To enable an optical connector to be attached and detached without using any lens for optical coupling by providing a connecting member which connects the optical connector to a cylindrical member optically and mechanically. CONSTITUTION:A semiconductor laser LD 1 is fixed to a mount base 2 in the center. Light emitted by the LD 1 is incident on an optical fiber (SMF) 3 is inserted and fixed in the center of a both-end polished ferrule 4.
