Patent JP-H01318853-A (JP)
Title: Controller for hot-air heater
Inventor: FUJISAWA YOSHINORI
IPC: F24H3/04
Filed: 1988-06-16
Abstract: PURPOSE:To make it possible to lower the temperature inside a casing through blowing off hot air from the casing by prolonging the operation of a blower when the temperature inside the casing is not lower than a predetermined temperature. CONSTITUTION:A draft controller 43 is provided with a timer 45 for operating a convection fan 13 continuedly after combustion at a burner is stopped, at the time of stopping the operation of a heater. When draft quantity is decreased due to closure of a suction port 12 or clogging of a filter 1, the temperature inside a casing 10a is raised. In such a case, sufficient cooling can not be achieved by only carrying out post-purge for a period of time set on the timer 45. When a bimetallic switch 36 is closed, therefore, the post-purge time is prolonged by a prolonging part 46.

Title: Light output control circuit of optical connection type equipment
Inventor: SUZUKI YUMIKO
IPC: G02B6/42
Filed: 1989-06-12
Abstract: PURPOSE:To prevent infrared light from entering the eyes of an operator by detecting the attachment/detachment state of an optical connector from the light reception state of a sensor photodetector and controlling the light output of a light emitting circuit according to the detection result. CONSTITUTION:When the optical connector 22 is detached from a receptacle 21, a sensor light receiver 13 receives a little reflected light from the optical connector 22, so the output of the sensor optical receiver 13 decreases. Consequently, the reference value of a differential amplifier 6 decreases and the control reference of a bias circuit to the output of a photodiode 3 decreases. Therefore, the output of the bias circuit 4 is limited in this state and the light emission output of a laser diode 2 is reduced or eliminated. Consequently, when the optical connector 22 is detached from the receptacle 21, the light emission output of the laser diode 2 is reduced to prevent the eyes of the operator, etc., from being damaged.

Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To provide a non-immersion type flowmeter utilizing a surface velocity sensor and a look-down water level sensor, and a device for installing of the flowmeter inside the manhole without requiring a worker to move into the manhole. SOLUTION: A velocity sensor and a water level sensor are so arranged to generate first and second energy beams 26 and 30 which 26 and 30 are transmitted to positions closer to each other on the surface of a fluid 10. The surface of the fluid 10 is made to reflect a signal radio wave to the sensors. A surface velocity signal is generated from a Doppler shift between incidence and reflection first beams and this signal is corrected to generate an average velocity signal. A water level signal is generated by determining a spatial distance between the sensors and the surface of the fluid 10 from the incidence and reflection first beams and by relating a change in the spatial distance of the level of the fluid according to the shape of a pipe. Thus, the flow rate of the fluid 10 can be calculated from the average speed signal and the fluid level signal.

Abstract: PURPOSE: To prevent generation of microwave discharge and enhance microwave melting efficiency, in microwave melting of unburned matter-contg. incineration ash, by adding an element easy to bond to carbon to the unburned matter.  
     CONSTITUTION: A sample of powdered incineration ash contg. unburned matter of a substance to be treated is collected to measure the amt. of the unburned matter.

Mixt. 4 is charged into resonance type melting furnace 3 with screw feeder 6, and microwaves are introduced from supply inlet 1 to allow furnace 3 to perfectly resonate with matching mechanism 2. By a dielectric loss due to a strong microwave electric field produced in furnace 3 the ash is melted to form a glassy substance. Part of the unburned matter is burned to CO 2 , yet a sort of amorphous carbon formed by insufficient supply of air floats on the glassy melt surface and causes microwave discahrge. At this time, the carbon is turned into Fe 3 C, CaC 2 , SiC, B 4 C or the like with the above additive and surrounded by the glassy melt to prevent generation of microwave discharge.
