Abstract: PURPOSE:To simplify constitution and to easily perform manufacture and adjustment, by performing demultiplexing and branching by providing a half mirror and a band- pass filter at a joint part by using a deformation prism whose corner is cut at a prescribed angle and a wedge type prism. CONSTITUTION:When a multiplex signals with wavelength lambda1 and lambda2 are inputted from an input port P0, they are converted to parallel rays by a focusing rod lens 6 and are introduced to a glass block 1. The half mirror 4 bi-branches the signal by reflection and transmission, and the signal one side is introduced to the band-pass filter 5 after being reflected, and the signal on the other side is introduced to a focusing rod lens 7 after being transmitted, and is converted to beam light, then, it is obtained at an output port P1. When the band-pass filter having a characteristic capable of transmitting the wavelength lambda1 and reflecting the wavelength lambda2 is used as the band-pass filter 5, the wavelength lambda1 is introduced to a focusing rod lens 8 and is converted to the beam light, then, it is obtained at an output port P2. Meanwhile, the wavelength lambda2 is introduced to a focusing rod lens 9 after being reflected, and is converted to the beam light, then, it is obtained at an output port P3. In such a way, it is possible to obtain an optical repeater whose constitution is simplified and manufacture and adjustment can be performed easily.

Title: Gas hot water heater
Inventor: NIIMURA NORIO
IPC: F23N1/08
Filed: 1991-06-20
Abstract: PURPOSE:To prevent incomplete combustion due to the shortage of oxygen by cutting off a gas flow passage doubly by means of a water flow responding valve which senses a gas solenoid valve and a water flow and actuates when operating a gas hot water heater for a specified time. CONSTITUTION:A gas solenoid valve 2 which opens/closes a gas flow passage 7 and a water solenoid valve 5 which opens/closes a water flow passage 4 are arranged to be closed after a specified time is over since the gas solenoid valve 2 and the water solenoid valve 5 start their service by means of a timer 10 built-in with a control circuit 9. When the water solenoid valve 5 is closed, a water governor fails to sense hydraulic pressure and closes a hydraulic pressure responding valve 8 separately installed to a gas flow passage 7 so that the gas flow passage 7 may be cut of doubly. This construction makes it possible to prevent incomplete combustion produced by the shortage of oxygen at a kitchen or the like by halting the operation in automatic mode when it drives for a specified time. Furthermore, even when the gas solenoid valve is subjected to leakage at that time, the hydraulic pressure responding valve is capable of cutting of the gas flow passage, thereby preventing the gas leakage doubly.
