Title: Mechanical scanning type ultrasonic probe
Inventor: TOKUNAGA WATARU
IPC: G01N29/24
Filed: 1992-11-24
Abstract: PURPOSE:To provide a mechanical scanning type ultrasonic probe which enables to obtain a better ultrasonic image by reducing a multiplex reflection to be generated between the surface of an ultrasonic transducer and an acoustic window to correct the refraction of an ultrasonic wave as caused when it passes through the acoustic window. CONSTITUTION:Centers 12 and 10 of curvature of a curved surface 11 of an internal wall and the curved surface 9 of an external wall of an acoustic window 2 are made different from the center of a rotating shaft 6 of a rotor 5 on which an ultrasonic transducer 7 for transmitting or receiving ultrasonic waves is fixed. The ultrasonic wave transmitted from the ultrasonic transducer 7 can be incident into the acoustic window 2 at an angle, not vertical thereto, which allows reduction in the multiplex reflection of the ultrasonic wave to be generated between the ultrasonic transducer 7 and the acoustic window 2. Since the center 12 of the curvature of the internal wall curved surface 11 and the center 10 of the curvature of the external wall curved surface 9 are differentiated, sound velocity differs when the ultrasonic wave passes through the acoustic window 2 thereby enabling the correction of refraction of the ultrasonic wave.

Title: Multistage compression refrigerating apparatus
Inventor: SUZUKI YOSHIBUMI
IPC: F25B1/10
Filed: 1992-11-24
Abstract: PURPOSE:To suppress a rise of the intermediate pressure during operation of a compressor so as to prevent a fall in the oiling efficiency by a method wherein, when an abnormal rise in the suction pressure of a compressor occurs during cooling operation, the compressor preceding the compressor in question by one stage is put under capacity control. CONSTITUTION:A semiclosed two stage compressor 1 has a compression mechanism for a low stage compression and an intermediate stage compression inside; after being compressed two times thereby, the refrigerant undergoes compression for the third time by a semiclosed, single-stage compressor 2, which effects a high stage compression, and is discharged as a high temperature, high pressure gas. The pressure of the refrigerant after the first stage compression is referred to as first intermediate pressure and the pressure after the second stage compression, as second intermediate pressure. When the second intermediate pressure abnormally rises and reaches a value set for a pressure switch 15, a low stage capacity- controlling solenoid valve 16 and an intermediate stage capacity-controlling solenoid valve 18 are opened and the low stage compression and the intermediate stage compressor starts capacity-controlled operation. When the first intermediate pressure abnormally rises and reaches a value set for a pressure switch 14, the low stage capacity-controlling solenoid valve 16 opens and the low stage compression of the compressor enters into capacity-controlled operation.

Filed: 1987-12-11
Abstract: PURPOSE:To prevent the defectiveness of a recorded trace by transferring a separate actuator to drive and displace a separate recording and reproducing element by one transfer body transferred by a common transport mechanism. CONSTITUTION:The title system is equipped with actuators ACT1 and ACT2 fitted to the same transfer body FA and used in an automatic control system composed for each of plural recording and reproducing elements H1 and H2.
