Title: Gas detector, gas warning device, combustion device and safety device for automobile
Inventor: SASAKI HIROSHI
IPC: F02D45/00
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To provide a gas detector by which a gas concentration can be detected with high reliability. SOLUTION: A light detecting sensor 11 is installed in such a way that a gas sensor 30 which is reacted with carbon monoxide gas in a measuring atmosphere and whose discoloration degree is changed according to its concentration and with the passage of time is used and that the discoloration degree of the gas sensor 30 is measured. A detection current from the light detecting sensor 11 is supplied to a variable oscillator 20 as a concentration detecting means, and a gas concentration is converted into a change in an oscillation frequency. The gas concentration is supplied to a control part 32. When it is at a prescribed gas concentration or higher, a transistor Q3 is turned on, and an alarm 34 is operated.  When a living-body imitation-type chemical sensor is used as the gas sensor 30, a sensor output which is related nearly to the gas concentration and to the generation time of the gas is obtained. Since the living-body imitation-type chemical sensor is reversible, a variation due to a change with the passage of time in the absorption characteristic and the diffusion characteristic of the gas is reduced.

Title: Highly efficient desulfurization method
Inventor: HAMASHIMA KAZUO
IPC: B01D53/46
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a dry two-step desulfurization method to carry out desulfurization at high efficiency while requiring only a small amount of a desulfurization agent by removing dust from a coal-fired combustion gas by passing the gas through a porous ceramic and simultaneously carrying out desulfurization again by a desulfurization gent supplied on the surface of the porous ceramic. SOLUTION: A high temperature combustion gas which is desulfurized in a furnace and calcium sulfate are introduced into the insides of porous ceramic cylindrical tubes 7 arranged vertically in parallel to each other from a gas inlet 5. Since the relatively large solid matter contained in the introduced gas does not pass the wall faces of the porous ceramic, the solid matter is led to the lower part of the cylindrical tubes 7 and discharged. On the other hand, the gas containing the desulfurization agent supplied by a nozzle 8 for supplying a desulfurization agent is desulfurized in a deposited layer formed in the inner circumferential face of the cylinders and passes through the porous ceramic tubes 7 while passing the voids of the tubes.  Further, the gas component and the solid matter are passed through a gas route 9 for a desulfurized gas and a gas for cleaning and led to a gas turbine out of a gas outlet 6.

IPC: B22C13/08
Filed: 1981-10-22
Abstract: PURPOSE:To prevent the flow of sand around the projection of a prototype and to prevent chipping away of shell molds in the stage of forming the shell mold having a recess by providing an enclosure that encircles said projection. CONSTITUTION:Sand 7 contg. a resin of a binder is put in a dump box 3, and a shutter 4 is closed. The box 3 is turned over and is put on a heated prototype 1 then a shutter 4 is puled to allow the sand 7 to drop onto the prototype 1. Then the resin contained in the sand 7 is melted by the heat of the prototype 1 and a shell mold layer 8 is formed on the surface of the prototype. When the device is turned over the unbound sand drops and the mold 8 is left around the prototype 1. Since there is an enclosure 6 around the projection 1a of the prototype 1, the shell mold layer around the projection 1a is isolated from the unbound sand around the same and the chipping away of the shell mold layer around the projection 1a by the flow of the sand is obviated. If the mask 2 is not used, the enclosure 6 may be mounted directly to the dump box 3.
