Title: Ultrasonic flaw detection method
Inventor: TAKADA HAJIME
IPC: G01N29/04
Filed: 1991-03-01
Abstract: PURPOSE:To suppress oscillation of waves with high frequency from an ultrasonic oscillator to a small level, suppress scattering noise due to structure to a small value and improve an S/N ratio by making high frequency voltage waveforms applied to the ultrasonic oscillator into sine waves having one cycle. CONSTITUTION:A clock circuit 11 outputs synchronization signals to a function generating circuit 12 with constant time intervals. The circuit 12 receives the outputs to output sine waves of one wavelength. The sine waves of one wavelength are amplified to an appropriate voltage by an amplifying circuit 13 and applied to a ultrasonic oscillator built into an ultrasonic transmitter/receiver 14, and transmitted ultrasonic pulses 51 are transmitted to a material 1 to be inspected. Ultrasonic pulses reflected on a surface, a bottom and an inner flaw of the material 1 to be inspected and ultrasonic pulses scattered by crystal structure again return to the transmitter/receiver 14 and are received. Then they are amplified by a receiving amplifying circuit 15 and their waveforms are displayed on an oscilloscope 16.

Title: Method for thermally molding sheet and apparatus therefor
Inventor: TANAKA TOSHIHIRO
IPC: B29C51/18
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for thermally molding a sheet which can easily mold an uneven shape of or corrugate the bottom or side of a product with a uniform thickness of the product without partial irregular thickness. SOLUTION: A sheet 1 is conveyed between a cavity mold 2 and a core mold 3 by a sheet clamping unit. Then, the sheet 1 is mounted on the mold 3. Thereafter, the mold 2 starts pressing the sheet 1. At this time, the peripheries of the four corners of the sheet 1 are waved (wrinkles). When the mold 2 is further dropped in this state, a retaining plate 5 starts dropping. Then, pressure molding is conducted. At this time, the sheet 1 is clamped from above a core mold side retaining plate 4 and below a cavity mold side retaining plate 5 while holding a predetermined clearance, and at the time of molding, the sheet 1 is drawn into the mold while sliding from the plates 4, 5 in the state applied by a predetermined applied pressure, and hence the sheet 1 can be molded while preventing the wrinkle without elongating the sheet l.

Title: Pedal sensor regulator for composite piano
Inventor: INABA TATSUYA
IPC: G10H1/32
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To rapidly execute position regulation of a pedal sensor which makes announcement by judging the press on the pedal down to a prescribed position and to obviate the occurrence of variation in the result of the regulation by providing the pedal sensor with an announcing means which is freely attachable and detachable to and from the pedal sensor. SOLUTION: The change in the resistance of the pedal sensor is inputted to a controller and a half pedal value is outputted to a regulator. A jig 6 for regulation has two regulation surfaces 61 and 62 varying in the height from the base surface. When the pedal 1 is pressed on until the pedal comes into contact with the regulation surface 61, a half pedal start state is attained. The phase of the pedal sensor is, thereupon, regulated and the result thereof is announced from the regulator. When the damper pedal is pressed on down to the regulation surface 61, a damper effect is completely released and even if the pedal is pressed on beyond this point, the state that reverberation time does not change is resulted. The position in the longitudinal direction of a bracket is regulated in such a manner that the prescribed announcement from the regulator is attained in this state.

Filed: 1995-02-01
Abstract: PURPOSE: To suppress the vibrating noise generated by mechanical unbalance by providing a mechanism for providing the rotary balance between a compressing piston and an expanding piston. CONSTITUTION: When a motor 3 rotatably drives a compressing piston 1 and an expanding piston 2 via connecting rods 31, 32 and a crankshaft 33, the piston 1 reciprocates in a compression cylinder 30 for forming a compressing space 11, and the piston 2 reciprocates in an expanding cylinder for forming an expanding space 21. Thus, the gas in the space 11 is supplied to the space 21 via the piston 2. In this case, a rotating mechanism 4 rotatably balances between the piston 1 and the piston 2. Thus, the vibration generated at the periphery by the mechanical foundation is prevented, and vibrating noise generated due to the unstable factor caused by the mechanical unbalance can be suppressed.
