Abstract: PROBLEM TO BE SOLVED: To perform display according to the causes of a failure in the safety device of combustion equipment. SOLUTION: In the safety device of combustion equipment for detecting flame failure and the abnormal increase in temperature, a temperature signal from a temperature signal generation means 2 for generating a temperature signal that changes continuously according to the temperature of a first measurement point P near the flame is inputted to safe operation means, and a safe operation is performed when temperature decreases. On the other hand, when the temperature of a second measurement point Q within the combustion device abnormally increases, input to the safe operation means of a temperature signal is broken by a circuit-breaking means 3 and the safe operation means performs a safe operation.  The input signal of the safer operation means is differentiated in terms of time by a differentiation means 6 and the value is compared with a setting value by a comparison means 7, thus discriminating the type of failure and performing different display on a display means 8 according to the type.

IPC: F02D41/04
Filed: 1994-12-20
Abstract: PURPOSE: To relax torque shock generated in association with the switching of an air-fuel ratio at the time of a driver hardly operating an accelerator even entering an upward slope during lean operation. CONSTITUTION: A judging means 21 judges whether an operation area is a preset lean operation area on the basis of the detection signal of an operating condition. At the time of judging the lean operation area, a setting means 22 sets an air-fuel ratio to the target value leaner than a stoichiometric air-fuel ratio. At the time of switching from this lean target value to the stoichiometric air-fuel ratio, a means 24 brings the air-fuel ratio target value close to the stoichiometric air-fuel ratio gradually at the air-fuel ratio enriching change speed at a time. On the basis of the set air-fuel ratio gradually brought close to the stoichiometric air-fuel ratio, an air-fuel ratio control means 25 performs air-fuel ratio control. When a vehicle speed condition comes off a specified range in the case of the condition of the lean operation area including the vehicle speed being within the specified range, a decrease-correcting means 26 decrease-corrects the air-fuel ratio enriching change speed set by a setting means 23.

Title: Manufacture of substrate for surface acoustic wave element
Inventor: KIMURA KOJI
IPC: H03H9/08
Filed: 1991-11-30
Abstract: PURPOSE:To improve the smoothness of the surface of the substrate, to decrease the specific resistance of an electrode formed on the substrate and to improve the surface acoustic wave characteristic by providing step in which an ion beam employing a rare gas radiates to a face on which an electrode for the substrate for the surface acoustic wave element is formed to the manufacture process. CONSTITUTION:The smoothness of a face of the substrate on which an electrode is formed by emitting an ion beam employing a rare gas to the substrate. Thus, the increase in the specific resistance of a metallic film deposited on the smoothed face of the substrate by vapor-deposition or the like is suppressed. Thus, even in the case of the surface acoustic wave element whose electrode film thickness is as thin as 1000A or so, a satisfactory characteristic is always obtained. For example, in-band ripple of the surface acoustic wave element is suppressed. Furthermore, it is possible to eliminate a stress of the substrate caused by polishment or the like by the radiation of ion beam employing the rare gas. Then the characteristic of the surface acoustic wave element is improved also at this point.

Abstract: PURPOSE: To enable the reliable measurement with a bulb which receives a hot or cold gas from a flow of a gas directly delivered from an evaporator, by a method that a pressure difference measuring unit acts against pressuring means to control the position of a flow rate control means and bulb approaches to a discharge pipe of the evaporator and supports a heating means and part of the bulb is located in the discharge pipe. CONSTITUTION: When a compressor 101 operates with full load, a resistor 20 is energized to heat a liq. 8 in a bulb 104 to push a spring 17 enough to open a piston 15, thereby flowing a liq. refrigerant from a condenser 102 into an evaporator 2. If the heat quantity obtd. from a circulating water in a vessel 4 lacks, the refrigerant fluid cannot enough evaporated by the evaporator 2, liq. droplets appear in a discharge pipe 1. When the carried liq. droplets begin to collide against a region 27 of the bulb 104, the bulb is cooled to reduce the pressure therein to reduce the pressure on a film 10, thereby closing the piston 15. A region where heat is given to the bulb and region where cold gas is received by the bulb and liq. housed therein are closely adjacent and hence the heat quantity need not move over a long Cu strip and hence an expansion valve 103 opens sensibly.
