Title: Optical fiber amplifier
Inventor: MURO SHINICHIRO
IPC: H04B10/03
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable optical fiber amplifier which can operate when a different gain is needed. SOLUTION: This amplifier can operate when a different gain is required by supplying excitation light from plural excitation light sources 3-1 to 3N to plural optical fiber amplifying parts 9-1 to 9-N through an optical star coupler 8 and using the sources 3-1 to 3-N having different wavelengths. Also, even if any source 3-1 fails, some other sources 3-2 to 3-N can take its place by using plural sources 3-1 to 3-N having the same wavelength. Thus, reliability of the amplifier 10 is improved.

Title: Refrigeration device
Inventor: MORITA MITSURU
IPC: F04B49/10
Filed: 1984-03-09
Abstract: PURPOSE:To save energy by controlling parallel solenoid valves of a refrigeration circuit by means of a thermostat for detecting lubricating oil temperature 50 as to keep the compressor temperature at a proper level. CONSTITUTION:When the temperature of lubricating oil 2 is relatively high in the summer season, a solenoid valve 4 is kept in an open state by means of a thermostat 9. Accordingly, the most part of refrigerant flows via the first refrigeration circuit to a condenser 5 due to a difference in the resistances of the flow passages of the refrigeration circuit, and refrigerant gas flows through a lubricating oil heating pipe 3 of the second refrigeration circuit, very slightly heating the lubricating oil 2. On the contrary, when the temperature of the lubricating oil 2 is low in the winter season, the solenoid valve 4 of the first refrigeration circuit keeps a closed state, and all high temperature refrigerant gas discharged from the compressor 1 flows through the lubricating oil heating pipe 3 of the second refrigeration circuit to heat the lubricating oil 2, allowing proper temperature to be kept.

Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which enables the integration of a bipolar transistor and a J-FET where both improvement in the mutual conductance of the J-FET and prevention of lowering of voltage breakdown are made consistent. SOLUTION: A P-type deffused layer 15b to be an upper gate region of a J-FET is formed shallowly, at the same time as a P-type deffusion layer 15a to be an active base of a bipolar transistor.
