Title: Turbine equipped with shroud made of ceramic
Inventor: TATSUMI TETSUO
IPC: F01D11/08
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To make a tip clearance extremely small at the time of a rated operation by adding elastic force which causes a shroud made out of ceramics to be directed to the inner side in the radial direction with respect to a metallic support member, and thereby supporting the shroud by the support member without a hitch. SOLUTION: A shroud 18A employed in this constitution is formed out of a ring body made of ceramics, and covers each turbine rotor blade 13 housed in a housing 11. A metallic support member 20 is supported by the housing 11 so as to be held in such a way as to be freely moved in the radial direction. An elastic force adding means 23 adds elastic force which causes the shroud 18A to be directed relatively in the radial direction with respect to the support member 20. By this constitution, there is no possibility that each turbine rotor blade is brought into contact with the shroud 18A at the transition time in an early stage of operations even if a tip clearance between each turbine rotor blade 13 and the shroud 18A is made sufficiently small at the time of a rated operation. Therefore, the efficiency of a turbine can positively be prevented from being degraded.

Therefore, thermal expansion difference at the guide tubes composed of the outer tube 6 and the inner tube 7 is absorbed by the fitting part between the atomizing medium nozzle 15 and liquid fuel injection nozzle 3. And when gas fuel is utilized as atomizing medium, there is no such a problem as leaking from an absorbing part for thermal expansion difference experienced in the past. Therefore, stable flow rate of atomizing medium is obtained and fine oil drop atomization is achieved by atomizing medium of small quantity and low pressure.

Title: Radio receiver
Inventor: ISHIZUE KAZUO
IPC: H04B1/18
Filed: 1982-04-19
Abstract: PURPOSE:To minimize spurious radiation from an antenna, by providing a trap circuit tuning to an oscillating frequency of a local oscillating circuit on an antenna input circuit. CONSTITUTION:A signal received at an antenna 1 is tuned by a coil 4 and a capacitor 5 constituting a tuning circuit and amplified at a high frequency amplifier circuit 6. A signal amplified at a frequency mixing circuit 7 is applied to a frequency mixing circuit 7 together with an oscillating output of a local oscillating circuit 8 and converted into an intermediate frequency signal at the circuit 7. The intermediate frequency signal is amplified at an intermediate frequency amplifier circuit (not shown) and detected at a detection circuit. The output of the local oscillating circuit 8 is not only applied to the circuit 7, but also given to the antenna in the opposite direction via the high-frequency amplifier circuit 6 and the tuning circuit. Since a trap circuit is inserted between the antenna input terminal and ground, the oscillation output of a local oscillation circuit 9 transmitted in the opposite direction via the circuit 6 and the tuning circuit is grounded via the trap circuit, allowing to suppress the oscillating power of the circuit 9 transmitted to the antenna 1 remarkably.

Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To surely wash a photomask used in the exposure stage of photolithographic work without requiring skill by rotating the photomask so that processing solution coming in contact with the photomask is removed, and drying it. SOLUTION: In the case of spraying the processing solution to the photomask 4, the photomask 4 is placed on a rotary table 3 and coated with the processing solution while it is slowly rotated. By rotating the photomask 4, the processing solution coming in contact with the photomask 4 is always new, and by rotating it slowly, the processing solution is hardly splashed to be mist spray. After the photomask 4 is washed with the processing solution, the photomask is rinsed with water. At such a time, it is rinsed from both upper and lower surfaces by using processing solution discharge nozzles 5 and 6. This is because the processing solution going round to the back due to the rinsing from the lower surface can be removed. By rotating the photomask 4 at high speed after rinsing, the water on the photomask 4 is shaken off so as to dry the photomask 4.
