Title: Noise reducing method
Inventor: RONARUDO RESURII POUERU
IPC: B63H1/26
Filed: 1989-12-20
Abstract: PURPOSE: To suppress noise by forming flat notches formed out of a plurality of triangular surfaces disposed along at least a part of respective surfaces adjacent to the trailing edge in at least one of main surfaces almost without interfering with the contour of a trailing edge. CONSTITUTION: In the propeller blade 1 of a hydrofoil, noise caused by vortex shedding generated at a trailing edge is suppressed by arranging notches 4 in a row 5 along the main surface 6 of the blade adjacent to the trailing edge. A row 7 similar to triangular notches 8 is formed along the back side surface 9 of the blade adjacent to the trailing edge. The notches 4 and 8 serve to interrupt the regular characteristics of vortex shedding, thus suppressing or inhibiting noise. The surfaces of the respective notches are flat, and the notches are continuous, therefore, no flat areas are at the surfaces 6 and 9 between adjacent notch corners. The two rows 5 and 7 of the notches 4, 8 are shifted sequentially each other, and the notch of one surface 6 of the blade is in a space to the other surface 9.

Title: Ultrasonic creep damage evaluating apparatus
Inventor: SHIRAI TASUKU
IPC: G01N29/44
Filed: 1994-12-09
Abstract: PURPOSE: To correctly evaluate a damaged amount by providing a divider for obtaining the N/B of noise value N to bottom echo value B in which the bottom echo and noise echo are integrated in the same frequency band as those of the frequency distributions of the bottom echo and the noise echo, and a display unit for evaluating and displaying a creep damage amount. CONSTITUTION: An ultrasonic probe 2 is mounted at a sample piece 1, and a signal from a spectrum analyzer 6 is input to a display unit 8 via a divider 7. The divider 7 obtains the ratio N/B of noise value N to echo value B in which the frequency distributions of the bottom echo and the noise echo are integrated in the same frequency band. The unit 8 evaluates and displays the creep damage amount from the correlation in which the N/B and the creep damage amount are displayed by logarithm to logarithm. As the creep damage amount increases, the noise value scattered by void is increased, while the bottom echo value is attenuated, the change of characteristic value is strengthened, and the creep damage can be evaluated for a steel material in which the void is scarcely generated.

Title: Vacuumizing method for curved passage for charged particles
Inventor: FURUYA SHINJI
IPC: H05H13/04
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To enhance vacuumizing of a cryopump by exhausting scattered gas molecules from an end station using a first cryopump, exhausting gas molecules discharged parallel with the wall surface using a second cryopump, and thereby vacuumizing the inside of the passage to a high degree of vacuum. SOLUTION: When a resist is coated to a board, much impurity gas is generated with incidence of an ion beam, and the gas molecules are going to diffuse into a passage 1, where those molecules diffused upon bombarding the wall surface of the passage 1 are exhausted upon flying into the suction hole of the first cryopump 4 opening large while it is surrounding the wall surface, so that diffused gas molecules from elsewhere can be exhausted with a high efficiency even if the passage is curved or non-curved. Other gas molecules diffusing following a track parallel with the wall surface reach the curved part of a magnet chamber 3, where the suction hole of the second cryopump 5 exists, so that the molecules fly into the hole and are exhausted by the pump 5.

Title: Waveform shaping circuit
Inventor: MASUDA YOSHIFUMI
IPC: H03K5/08
Filed: 1993-12-27
Abstract: PURPOSE:To shape a waveform by generating a stable comparison signal while using a voltage with an input voltage used as a reference as a comparing voltage. CONSTITUTION:A select signal output means 2 is turned on and off corresponding to an output from a differential amplifier 3. Based on an input voltage VB, a comparison voltage setting means 1 sets a comparison voltage VC. The voltage VC is delayed to rise or fall of the input voltage VB because of the response characteristics of a photodetector, the threshold voltages of respective transistors inside the waveform forming circuit and the transient characteristics of switching or the like. Thus, when an input signal B is changed, the voltage VB of the input signal crosses the comparison voltage VC. The rise and fall of the input voltage VB are detected by utilizing this crossing of respective voltages VB and VC caused by the delay inside the circuit.
