Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To execute safety action against CO in combustion exhaust, using information on the combustion capacity and air volume from a fan. SOLUTION: A CO sensor 11 detects the CO concentration in exhaust gas. A combustion time-measuring means 13 measures the time from the start of combustion. A data memory 12 is preliminarily given data for determining, on the supposition that exhaust gas has leaked into a room, the time preceding danger, after an elapse of which the CO concentration in the room reaches a hazardous level, set for each of variables of the combustion capacity and for each of variables of the air volume from a fan. A CO safety action part 14 obtains information on the combustion capacity and air volume from the fan and selects from the data in the data memory 12 data for determining the time preceding danger that corresponds to the combustion capacity and the air volume from the fan.  When the time of danger has come which matches the CO concentrations in the exhaust under detection by the CO sensor 11 from the start of combustion, it is decided that the CO concentration in the room has reached a hazardous level of CO poisoning and CO sefety action, such as stopping of the combustion, is executed.

Title: Electromagnetic ultrasonic wave generating device
Inventor: SUGINO KAZUMI
IPC: G01N29/04
Filed: 1987-08-20
Abstract: PURPOSE:To reduce the size of the device on the whole by extracting a rod- shaped magnetic core suddenly in an initial state where the rod-shaped magnetic core is excited by a solenoid coil, decreasing the inductance of a circuit, and supplying a current which increases abruptly to a generating coil. CONSTITUTION:A capacitor 7 is charged with the DC voltage of a DC power source 5 through a charging resistance 6. When a switch 9 is closed, the discharging current I of the capacitor 7 flows through a damping resistor 8 and also flows to a solenoid coil 10 to excites the rod-shaped magnetic core 11 inserted into the coil 10. When a driving mechanism 14 extracts the magnetic core 11 from the coil 10 abruptly, the inductance of the coil 10 is reduced suddenly to 1/mu, where mu is the magnetic permeability of the magnetic core 11. The current I flowing to an excitation part 12 varies by about mu times because the inductance varies abruptly to mu. Thus, the device is reduced in size on the whole.
