IPC: F23N5/24
Filed: 1979-09-19
Abstract: PURPOSE: To prevent occurrence of accidents due to troubles caused with a heat- sensitive resistance element, component parts constituting a circuit or others, by  stopping oscillation of an oscillator at the time when some trouble is caused,  through comparison of the oscillation voltage of the oscillator and the output signal  of the heat-sensitive resistance element.

On the other hand, when combustion flame is extinguished by some reason or other, heating of heat-sensitive resistance element 34 by combustion flame is stopped, so that its resistance becomes higher than a predetermined value. Resultantly, oscillation of a comparator 27 is stopped and solenoid valve 37 is closed, so that effluence of gas can be prevented. Similarly, in case that some trouble is caused with the oven at the heat-sensitive resistance element 34, solenoid valve 37 is also closed.

Title: Displacement sensor
Inventor: AKASHI HIROSHI
IPC: G01B13/24
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To accurately detect the amount of the displacement of a work without detecting minute protrusions by blowing air against the work and always maintaining the distance to the work constant. SOLUTION: An air holding device A which is held in a freely moving manner in the up and down directions blows high pressure air C to the top of a work 7 which moves in a horizontal direction. When a distance H between an operating surface 5 and the work 7 is large, the device A moves toward the work 7 by the reduction in the pressure of the high pressure air flow going through the space between the two. If the distance H is small, the pressure of the space is increased by an air cushion effect, the device A is pushed up from the work 7 and the distance H between the two is always maintained constant (normally approximately 2mm).  Thus, the device A moves in the up and down directions for the amount which is same as the amount of the displacement without being affected by the minute protrusions located on the surface of the work 7 during the measurements of the warp, the waviness and the steps of the work surfaces. Therefore, the amount of the displacement of the work 7 is detected by detecting the amount of the movement of the device A.
