IPC: F23N5/24
Filed: 1994-03-30
Abstract: PURPOSE:To reduce ignition noise caused by excessive supplying of fuel during ignition at a subsequent operation even in the case that a power supply is turned off due to a power failure during combustion by a method wherein both a flow rate regulating valve and a pressure relief valve are opened for a specified period of time in the case that the power supply is recovered from its off-state to its on-state. CONSTITUTION:A controller 16 releases a flow rate regulating valve 6 and a pressure relief valve 10 for a specified period of time in the case that a power supply is recovered from its off-state to its on-state when the power supply for a combustion device is turned off due to a power failure during an operation of a petroleum combustion device. With such an arrangement as above, petroleum remained within a return passage 7 while being kept at its high pressure due to a power failure in the midway of the operation passes from a return passage 7 to a flow rate regulating valve 6 in a petroleum supplying passage 3, bypasses the pressure releasing valve 10, is released toward an upstream side of a first pump 4, resulting in that a pressure within the return passage 7 is reduced. With such an arrangement as above, it is possible to reduce ignition noise caused by excessive supplying of fuel during ignition at a time of starting a combustion operation after the power supply is recovered.

Abstract: PURPOSE:To highly integrate a semiconductor device by simultaneously forming elements on not only one surface of a semiconductor but more than two surfaces including back and side surfaces. CONSTITUTION:An SiO2 film 7 is formed on an Si substrate 1, a thin film 2 of single crystal of almost single crystal is formed, and an SiO2 film 4 and a polysilicon gate 3 are formed. Diffused layers 6, 6' are formed on the film 2, the gate 3 is used as a word line, and the layer 6 is used as a bit line. The formation of the diffused layer is prevented on the side faces of the thin film 2 at the bit line side 6, and the layer 6' is formed on the side face of opposite side. When the voltage for inverting the polarity of the film 2 is applied to the substrate 1, a node (diffused layer 6') at opposite side to the bit line of a switching element is connected to the back surface 8 of the thin film. Accordingly, the capacity between the back surface 8 and the substrate 1 can be used as the capacity of dynamic RAM, thereby remarkably reducing the area. It is effective to provide a diffused layer 9 due to the reduction in the resistance of the substrate 1. According to this configuration, a dynamic RAM of high integration is completed in which the switch element is arranged on the front surface and a capacitive element is arranged on the back surface.

When a frequency difference is found by a numerical formula, pi1Hz is indicated correctly. In a frequency-sweeping spectrum analysis, the frequency difference can be found also on the basis of frequencies at minimum values (a), (b), (c) or on the basis of frequency intervals of A, B, C.
