Title: Detection of fluid leakage
Inventor: HONDA KIICHIRO
IPC: G01M3/24
Filed: 1986-08-05
Abstract: PURPOSE:To enable the discriminating of possible leak of a fluid accurately even during the operation, by judging the presence of a leaked fluid based on the existence of cyclic changes in the level of a sound as measured with an acoustic measuring device and acoustic frequency thereof. CONSTITUTION:Sounds collected with microphones 3 and 4 are amplified with an amplifier 10 and then, inputted into a monitor switch 14. The intensity of the sounds is monitored while the signals amplified are inputted into a subtractor 11. With the subtractor 11, a difference between two signals is determined to compute a rate of change in the deviation with a change rate computing unit 12 and depending on the changes, noises are checked whether they are caused by the injection of a soot blower. This enables discrimination of possible leak of a fluid accurately not only during the stoppage of the soot blower but also during the operation thereof.

Abstract: PURPOSE:To enhance a production yield of a metal pattern by a method wherein an insulating film spacer is formed by continuously changing an etching rate of this spacer to be large on the side of a semiconductor substrate and to be small on the side of the surface in such a way that a side-etching amount during an etching operation of the insulating film spacer is smaller than a film thickness of the spacer. CONSTITUTION:A spacer film 11 composed of SiNx:H is formed on a semiinsulating GaAs substrate 101 by a plasma CVD method. During this process, a parameter of one out of a ratio of a gas flow rate, a pressure inside a chamber and the high-frequency electric power to be impressed is changed continuously among conditions to form the SiNx:H spacer film; an etching rate of the spacer film is reduced continuously from the side of the substrate to the side of the surface. In succession, a photoresist film 12 is applied to the spacer film 11; a development operation is executed; an opening 22 is made in the photoresist film; the SiNx:H spacer film 11 at this opening 22 is etched by using an NH4F/HF solution; a side etching part 21 is formed. After that, a metal layer 13, e.g. Al, is evaporated; the metal is removed by a lift-off method; a metal pattern 23 is formed.

Title: Data transfer system between external memory device
Inventor: KATSURAGAWA SHOJI
IPC: G06F3/06
Filed: 1985-08-21
Abstract: PURPOSE:To improve the processing efficiency by reading data from an external memory device, storing it in a memory and writing this data in the other external memory without using a general-purpose bus. CONSTITUTION:When it is judged that the write operation of all the prescribed data in a magnetic tape device 5 is terminated, the effect is reported to a host processor 1, and a series of processing operations is completed. When the data is transferred from a fixed disk device 4 as the external memory to the magnetic tape device 5, the general-purpose bus 6 is occupied only during the transfer of the instruction and the termination of the processing. Since the general-purpose bus 6 is not occupied while the data transfer is executed, which requires the longest time, the host processor 1 can execute the other operations during the data transfer. Therefore the processing efficiency can be improved as a whole.

Title: Oscillation circuit
Inventor: MAKISHIMA YOJI
IPC: H03L7/08
Filed: 1989-07-18
Abstract: PURPOSE:To obtain an oscillation circuit with high stability although the circuit is compact, energy consumption is reduced and cost is lowered by storing the compensation control voltage value of a voltage control oscillator(VCO) corresponding to each temperature as a digital value in an EEPROM, reading the value by an output from a temperature sensor, converting this value to an analog value, and controlling the VCO. CONSTITUTION:In the oscillation circuit using the VCO, exact temperature compensation is executed by storing the compensation control voltage value of a VCO 5 corresponding to each temperature as the digital value in an EEPROM 3, reading the compensation control voltage value corresponding to each temperature by the output from a temperature sensor 1, converting this value to the analog value, inputting it to the VCO 5 and controlling the VCO 5. For writing the value into the EEPROM 3, it can be easily executed by using a signal, for which the compensation control voltage value to be applied to the VCO 5 is digitized, when phase lock is executed to the output of the VCO 5 to the input of a reference frequency. Thus, while making the circuit compact, reducing the energy consumption and lowering the cost, the stability less than 1ppm can easily be obtained.

Abstract: PURPOSE:To form a conversion mechanism in which the electricity having three stopping positions is converted into five mechanisms by a method wherein a difference is caused in the attraction force according to the direction of the current flowing through the coil of an electromagnet by combining the electromagnet and a permanent magnet. CONSTITUTION:A current is permitted to flow on a coil 4 in the direction which helps the generation of magnetic flux on a permanent magnet 5 when the attraction force in the air-gap 6 by compound magnetic flux exceeds the full load of the magnetic iron 2 including the load of a tensile spring 13 at the first stop position of movable magnetic iron 2, said attracting force goes back to the second stop position where the magnet 5 is finally fixed closely to a stationary magnetic pole 3.
