Title: Measuring device for high frequency excitation plasma
Inventor: OMI TADAHIRO
IPC: H05H1/00
Filed: 1993-01-15
Abstract: PURPOSE:To precisely measure plasma potential by setting the absolute value of the impedance between a first electrode and earthing 5 times or more the absolute value of the impedance between the first electrode and a plasma. CONSTITUTION:To minimize the impedance of a sheath, an electrode 103 is connected to an electrode 101 through a capacitor, and no direct current is thus carried to the electrode 103. Since the direct current is only carried through the electrode 101 with a small surface area, it hardly disturb a plasma. A filter 111 is provided on a probe, whereby the impedance of the probe in an excitation frequency is increased. For example, the absolute value of the impedance of the filter 111 in excitation frequency 200MHz is 6.2kOMEGA, the reactance of a solid wire 110 is 160OMEGA, and the absolute value of the impedance of the electrode 101 to earthing is surely 6kOMEGA or more. Thus, each plasma parameter can be precisely measured.

Title: Tape cassette
Inventor: KISANUKI AKITSUGU
IPC: G11B23/087
Filed: 1984-02-09
Abstract: PURPOSE:To make the structure strong by providing a strut to the inside of a cassette half and providing a fitting part that fits to the strut to the inside of another cassette half. CONSTITUTION:A magnetic tape 8 is loaded between two reels 6, 7 along the front face of a cassette case 5. In the longer half 3, a columnar strut 9 is formed near the back side in the center of inside. In the upper half 2, a cylindrical fitting part 10 is formed to the inside at a position corresponding to the strut 9. The diameter of the strut 9 and the inner diameter of the fitting part 10 is so determined that the strut 9 is somewhat pressed into the fitting part 10 and fitted without leaving space. These tightly fitted strut 9 and fitting part 10 function to suppress the movement of upper and lower halves 2, 3 in the direction to deviate from each other. Accordingly, upper and lower halves 2, 3 are combined in the state that the movement in the direction to deviate from each other is restrained. Consequently, even when torsional force acts on the tape cassette 1, upper and lower halves 2, 3 do not cause the deviation. Thus, the structure becomes very strong against torsion.

Abstract: PURPOSE:To obtain continuity of the horizontal synchronizing signal and the color signal, by delaying the luminance signal and the color signal by prescribed lines at the high-speed reproducing time and by advancing these signals by prescribed lines at the slow, still, or reverse reproducing time. CONSTITUTION:The signal reproduced by head 7 is led to envelope detector 20, and the envelope is detected to obtain pulse signal 27 indicating the discontinuous point of the horizontal synchronizing signal and the color signal. This signal 27 is led to FFs 22 and 23, and control signals 28 and 29 of switches 15 and 19 are obtained. At the high-speed reproducing time, the luminance signal is delayed by 0.5H and the color signal is delayed by 0.5H if discontinuity occurs. Meanwhile, if discontinuity occurs at the slow, still, or revese reproducing time, the luminance signal is advanced by 0.5H, and the color signal is advanced by 0.5H. As a result, continuity of the horizontal synchronizing signal and the color signal is obtained in any case of special reproducing.

Title: Tri-state signal drive circuit
Inventor: FUKUDA MAKOTO
IPC: H03K19/0175
Filed: 1988-02-03
Abstract: PURPOSE:To generate an output signal with less delay by using an input signal and charging a static capacitance existing on an output line of a tri-state buffer rapidly so as to set the potential to a desired potential. CONSTITUTION:A timing generating circuit 2 drives actively a tri-state buffer 1 with respect to a head portion of an input signal A, sends an output signal B of an H level corresponding to the H level of the input signal A to an output line, the static capacitance in existing on the output line is charged rapidly to bring the level to the H level. After the input signal is used to transit the level of the output line to the H level, the timing generating circuit 2 uses the signal at the end of the input signal A retarded by a delay circuit 3 to inactivately drive the tri-state buffer 1. Thus, when the tri-state buffer 1 transits to the active and the inactive state, the output signal B without delay due to the static capacitance of the output line is produced.

Title: Cleansing method for gas turbine casing and cleansing device thereof
Inventor: GOTOU SOTOHARU
IPC: F02B77/04
Filed: 1982-02-16
Abstract: PURPOSE:To enable cleansing of a gas turbine casing, by a method wherein the aqueous solution of a chemical compound gasified at lower than a given temperature is jetted into a working gas pipe installed at the inlet of a gas turbine driven by combustion gas. CONSTITUTION:The aqueous solution in a chemical liquid tank 7, gasified at a temperature lower than about 400 deg.C, is jetted into a gas turbine 4 through a spray nozzle 6. The sprayed aqueous solution percolates through a scale once. Water impregnated through the scale as a result of rise in an exhaust temperature due to the increase in an engine load is evaporated, and only salts are left. A first chemical reaction occurs to the salts as a result of a boiling, a fusion starts at about 100-150 deg.C to bring it into liquid, and a boiling occurs again to cause a second chemical reaction. If temperature rises to higher than about 200-250 deg.C, it is gasified, and if rising to higher than about 300 deg.C, it is violently gasified. Finally, all the salts are gasified, and a pressure of gas produced at the inside of the porous scale peels and removes a scale from a metal surface.

IPC: B29L22/00
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to uniformly mold the thickness of a hollow product by increasing the flowing resistance of the resin extruded by the movement of a floating core to a sub-cavity after the start of moving the core, and decelerating the flowing velocity. SOLUTION: A main molding is molded by a main cavity 1, and a sub- molding is molded by a sub-cavity 7. The sub-molding is used for a product or reuse. Pressurized fluid is press injected from a pressure pump 5 in the state that the cavity 1 is fully filled with a molten resin, a floating core 4 is moved, and the resin is extruded from a communication port 6 to a primary sub-cavity 7a. The extruded resin is fed to a secondary sub-cavity 7b to become a sub- molding. The opening area of the connecting port 8 communicating with the cavities 7a, 7b is reduced smaller than that of the port 6. Thus, the resin flowing velocity to the cavity 7 is decelerated, and the moving speed of the core 4 is suppressed to obtain a molding having uniform thickness.

Title: Radio equipment
Inventor: YOSHIDA KOJI
IPC: H04B1/10
Filed: 1995-02-13
Abstract: PURPOSE: To perform switching between transmission and reception without stopping any of oscillator for up-conversion and an oscillator for down- conversion by oscillating the oscillator for up-conversion of a transmission signal with the oscillation frequency different from that for transmission at the time of reception. CONSTITUTION: In the case of communication in the TDD system, the oscillation frequency of a VCO 11 which modulates transmission data and the frequency of a reception signal are equal to each other. Consequently, the reception sensitivity of the reception signal is affected in a mixer 5 which mixes a reception signal and the reception signal to down-convert the reception signal to an IF signal. Since it is necessary to exclude this influence, the oscillation frequency or the VCO 11 which modulates transmission data is shifted by a band-pass filter 3 which limits the band of the reception IF signal. This shift of the oscillation frequency of the VCO 11 is controlled by operating the modulation input of the VCO 11 by a control part 14.
