摘要： PURPOSE:To form a CVD film of good quality on a substrate by a method wherein the introducing hole of reaction gas is formed at a point within the range of a specific distance from an electron cyclotron resonant point. CONSTITUTION:The intensity of a magnetic field is formed by a coil 16 and an auxiliary coil 16' in the divergent magnetic field distribution in which the degree of intensity is gradually made lower as going to the substrate 17 to be treated from a plasma generating chamber, and the reaction gas introduced from a reaction gas introducing hole 19 is ionized by the plasma stream generated by the gas introduced from a plasma generating gas introducing hole 18. At that time, when the resonant point of an electronic cyclotron is formed at the position X-X' as shown in the diagram, the position of the introduction hole 19 is provided within the range of 50 mm to the side of the substrate 17 to be treated and 200mm to the side of a microwaveguide 15. As a result, a CVD film of excellent quality and uniformity can be formed on the substrate 17.

摘要： PURPOSE:To attain a stable radio communication while S/N is kept constant even if noise level is changed by controlling a high frequency output of a radio transmitter in response to a noise detection level. CONSTITUTION:A noise detector 10 is added to the transmission circuit of a radio transmitter, a noise caught by a transmission antenna 4 is rectified and extracted as a DC signal, the DC signal controls a current supplied to the transmission circuit to adjust the high frequency output automatically. That is, when the noise level is increased, the noise signal is rectified and the DC signal level rises and the supply current to the transmission circuit controlled by the DC signal is increased and the high frequency output is increased attended therewith. Conversely, when the noise level is decreased, the DC signal is decreased, the supply current is decreased and the high frequency output is lowered. Thus, the high frequency output is increased/decreased in response to the change in the external noise level to ensure a prescribed S/N and stable communication is attained by using a radio equipment with a minute output.

摘要： PURPOSE:To promote the improvement of efficiency, by providing plural sets of extraction booster compressors switching their operation to parallel and series running in accordance with a change of flow amount and pressure ratio. CONSTITUTION:Plural sets of extraction booster compressors 8-1, 2, 3 are connected with a compressor 3. When pressure ratio is in a large value with a small amount of flow, two sets of the compressors are driven in series running operation by opening valves 16-1, 2, and 17-1. When the pressure ratio is in a small value with the large amount of flow, two sets of the compressors are driven in parallel running operation by closing the valve 16-1 while opening valves 16-3, 17-2, 3. In this way, efficiency can be enhanced by small decreasing a throttle amount of pressure resisting structures of an inlet valve or the like the extraction booster compressor.

摘要： PURPOSE:To control temperature rise and drop at the time of the operation and the shutdown of a gas turbine to prevent its heat cycle fatigue by supplying heated air into the gas turbine in such condition as it has been tightly closed after its shutdown. CONSTITUTION:Each of shutoff dampers 6, 7 is opened, and on the other hand, each of separation valves 3, 5 is closed in starting a gas turbine 13 and thereafter during its operation. After the shutdown of the gas turbine 13, each of the shutoff dampers 6, 7 is closed, and the gas turbine 13 is thereby tightly shut to prevent its heat release, and is fed with air 26 by a blower 1, and moreover heated by a heater 2. In this case, an air 26 is discharged through a bypass valve 4 into an atmosphere 25 until the air 26 reaches a fixed temperature. When the air 26 has reached the said temperature, the bypass valve 4 is closed, and on the other hand, each of the separation valves 3, 5 is opened to supply a high temperature air 27 into a combustor 12 and the gas turbine 13. Temperature drop occurring in the gas turbine 13 can thus be controlled.

摘要： PURPOSE:To immediately diagnose a foreign matter collision by detecting a collision sound by an acoustic sensor provided to a baring part and processing its output signal. CONSTITUTION:The output of the acoustic sensor 1 is amplified 2 and detected 3. When a small foreign grain strikes on a rotary blade, an acoustic signal due to the collision is generated, a mean value circuit 4 converts the output of an amplifying circuit 2 into a mean value, and a V/F converter 5 outputs pulses proportional to a voltage value; and a counter 6a outputs a DC voltage proportional to counted values and a standard device 7a outputs a signal for operating an alarm 10a when the output of the counter 6a exceeds a standard value. Then if a large foreign grain strikes, an impulsive waveform is generated, detected 3, and compared 8 with a threshold voltage, and a signal exceeding a voltage E is converted into a pulse signal as the output of the comparator 8, thereby outputting a signal for operating an alarm 10c through a counter 6b and a standard device 7b. The outputs of small-grain and large- grain collision detecting circuits 20 and 30 are inputted to a small- and large-grain simultaneous generating and detecting circuit 40 and an alarm is generated 10b when the AND result is satisfied.

摘要： PURPOSE:To obtain the superconductive device having a load-supporting body of large rigidity limit as a whole by a method wherein the titled superconductive device is constructed in such a manner that the outer circumferential side of a multiple cylinder is connected to an ultralow temperature part, and the inner circumferential side is connected to a high temperature part. CONSTITUTION:In a heat-insulating load supporting member 10, a shaft 9 is connected to an outer case 3, and an outer cylinder 5 is connected to an inner case 1 through the intermediary of an electromagnetic force supporting member 8 respectively. On the side of an ultralow temperature (outer circumferential side), a carbon fiber reinforced plastic (CFRP) cylinder 6 is arranged, and a glass fiber reinforced plastic (GFRP) cylinder 8 is arranged on the side of normal temperature (inner circumferential side) respectively. In coupled parts A and B, as the temperature of the outer circumferential side is lower than that of the inner circumferential side, the outside of the coupled parts contracts more than the inside, the effect of expansion-fit performed when the supporting member is manufactured can be reinforced further, the CFRP coupled part having small interlayer exforiation-resisting force can also be reinforced sufficiently, and the desired load supporting member of high rigidity and high strength can be obtained as a whole.
