Title: Sensor for ultrasonic range finder
Inventor: YOSHIDA YOSHIMICHI
IPC: G01S7/52
Filed: 1985-04-19
Abstract: PURPOSE:To execute a measurement with a high accuracy even in case of a high temperature and a room temperature atmosphere, by providing a 1/4 wavelength layer which has formed a fine foam by a microballoon made of glass. CONSTITUTION:The first - the fourth 1/4 wavelength layers 18-21 are formed so that the percentage of content of its microballoon 23 made of glass becomes larger gradually from an electrode 15 side. Especially, the fourth 1/4 wavelength layer 21 of its outermost layer is formed in the almost same way as th acoustic impedance of gas 24 such as air, etc. When an ultrasonic wave 16 transmits through the first - the fourth 1/4 wavelength layers 18-21 and it is radiated into the gas 24, since each acoustic impedance of the fourth 1/4 wavelength layer 21 and the gas 24 is almost the same, the acoustic radiation efficiency is made as high as possible, and a measurement can be executed with a high accuracy.

Title: Liquid pressure clutching device
Inventor: TAKAHASHI TAKASHI
IPC: F16D25/04
Filed: 1983-05-16
Abstract: PURPOSE:To prevent rupture of bellows installed at a cylinder, by forming the bellows from a flexible diaphragm made of a plurality of thin films laminated. CONSTITUTION:A cylinder 11 is equipped with bellows 13 in the form of a ring, which are expanded by fluid pressure so as to press a friction plate 7 for clutching. The bellows 13 are formed from corrugated flexible diaphragms 19, 20 made of a plurality of thin films 19a, 19b, 20a, 20b laminated one over another. This gives the bellows 13 a greater stiffness in radial direction than its axial direction so as to provide possibility of enlarging the expansion stroke in the axial direction while the bellows are restricted from expanding in the radial direction. Thus rupture of bellows 13 is prevented.

Title: Cathode-ray tube
Inventor: KISHIMOTO SHIYUNICHI
IPC: H01J29/64
Filed: 1980-06-20
Abstract: PURPOSE:To form on a phosphor screen a spot with small diametrical width in the scanning direction by focussing an electron beam which passed through an aperture with a smaller aspect ratio than that of the beam spot on the phosphor screen, using a ring-shaped permanent magnet. CONSTITUTION:An electron gun EG used for a cathode-ray tube consists of a cathode K, current control electrode G1, beam lead electrode G2, acceleration electrode G3 and beam focussing magnet ring M. An aperture [A] with a smaller aspect ratio (for example, 2:1) than that (for example, 3:1) of the cross section which is irradiated on a phosphor screen is formed at a current limiting electrode G1 and the magnet ring M is fixed to the acceleration electrode G3 by an insulating jig S so that its centering can universally adjusted. This can form a lengthwise long beam whose aspect ratio is not exceedingly large and prevent the saturation of the color of a beam index table and deterioration of color purity.

Title: Color television picture receiver
Inventor: TOOYAMA AKIRA
IPC: H04N9/24
Filed: 1978-07-11
Abstract: PURPOSE: To secure an accurate color synchronization even with variation of the elecron beam scanning speed by securing the color synchronization with the signal which changed the frequency of the index signal into 1/2 via the polarity switching circuit.  
     CONSTITUTION: When the scanning is given via the electron beam to the index fluorescent substance stripes 11 over horizontal scan starting part 9 and effective screen part 6 comprising fluorescent substance stripes of red (R), green (G) and blue (B) each on the inner surface of the beam index type Braun tube, original index signal S 10  is generated. For this signal S 10 , the polarity of the pulse is inverted with every second pulse via polarity switching circuit, and the signal featuring 1/2 frequency of signal S 10  is used as index signal S 1  for the color synchronization. Thus, owing to 1/2 frequency of signal S 1 , the frequency fluctuation range of the disturbance spectrum existing at both sides of the index information contained in the signal is narrowed even with the fluctuation of the electron beam scanning speed. As a result, the disturbance spectrum can be eliminated assuredly, thus securing an accurate color synchronization.

Filed: 1979-07-03
Abstract: PURPOSE: To detect the abnormality of pressing in an early time and perform automatic stopping of the press by installing a sensor to a male die and transmitting the disturbance of the pulses generated when working operation is abnormal to a press control unit by way of a signal processing circuit.  
     CONSTITUTION: With the pressing operation in a normal state, a fixed space is held between the contactless switch 6 installed to a male die 4 and the metal piece 7 installed to a female die 5, and the magnetic force signal of a regular and correct waveform is generated from the contactless switch 6. If abnormality such as damage of the male die 4 or female die 5 occurs, the pulses generated from the contactless switch 6 disturb. The disturbed signal pulses cause the signal processing circuit of an abnormality detecting monitor 9 to operate and the alarm output and stop output in a signal generating unit 13 are obtained. By this stop output, the operation of an automatic press device 1 is rapidly stopped by way of a press control unit 12.
