Title: Optical communication system
Inventor: TOMIOKA TAZUKO
IPC: H04B10/516
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To make an internal semiconductor laser of a slave station operate stably in the case that the slave station is installed outdoor and to simplify wavelength control at wavelength multiplex in the communication system where optical signals from a plurality of distributed slave stations are confluent and the resulting signal is sent to a control station. SOLUTION: A comb-line wave generator 4 is used for a light source in a bus type optical fiber network and placed at an end of the bus fiber 1. Since the light source is managed at one location and care about production of a beat noise is not required because a comb-line wave is in use. Furthermore, since no light source such as a semiconductor laser element is in use in slave stations 5-1-5-n, instability of the semiconductor laser element is not concerned. Furthermore, a variable optical filter 6 of band block type is used for a modulator for the slave stations. Thus, it is not required to provide a complicated configuration such as Add/Drop using a wavelength multiplexer/demultiplexer and the system can be simplified.

Title: Hot water storing type hot water supply device
Inventor: FUKAHORI MASAHISA
IPC: F24H7/02
Filed: 1990-11-20
Abstract: PURPOSE:To supply a hot water at high temperature to the load side by suppressing the decrease of hot water quantity even at the time of large quantity consumption of a peak loading by providing a heat storage chamber, in which a high temperature heat storage material which phase-changes by taking heat away from a hot water to be fed through a heating water supply line is contained, in a hot water storage tank. CONSTITUTION:By opening a second flow valve 9, a hot water HW in a hot water storage tank 1 is supplied to the load side such as a shower equipment. When the water level in the hot water storage tank 1 has descended, a normal temperature water supply line is formed by closing a first flow valve 6 and opening the by-pass side of a 3-way valve 7. Under this condition, water W from a water receiving tank 2 is fed in the hot water storage tank 1 through a by-pass passage 14, and the water level in the hot water storage tank 1 is restored. At this time, if the temperature of the water W is, e.g. approximately 7 deg.C, the temperature difference with a high temperature heat storage material 17 is large, and heat can be taken out efficiently. Therefore, even if a large quantity of hot water HW is consumed at this time, sufficiently heated hot water HW can be supplied from the hot water storage tank 1.

Filed: 1988-12-15
Abstract: PURPOSE:To make it possible to distinguish and detect solid, water and oil by providing a plurality of sensor parts comprising a solid detecting part, a liquid detecting part and an oil detecting part in the longitudinal direction. CONSTITUTION:At first, a light signal is outputted from an electricity/light transducer 8 and inputted into optical fibers 1 at each sensor part S of a solid detecting part 13, a liquid detecting part 14 and an oil detecting part 15 through a directional coupler 9. The light signal is transmitted through the optical fiber 1. When a specimen is attached to the sensor part S, part of the light signal is not transmitted at the point, and a transmission loss is generated. Therefore, the reflected light which is transmitted from each detecting part 4 of the sensor part S as the backward scattered light is converted into the electric signal through a light/electricity transducer 10. The electric signal is amplified in an amplifier 11 and processed in an averaging circuit 12. The result is visually observed through a CRT 7 or processed in a computer. Thus the amount of fluctuation in transmission at each detecting point 4 is measured, and the specimen which is attached to each sensor part S is distinguished as solid, water or oil and can be detected as quality.
