Filed: 1986-02-13
Abstract: PURPOSE:To form an antenna reflector face with high rigidity by providing plural expansion mechanisms each consisting of an expanding angle synchronizing device, plural expansion arms and a link part fitted to the tip of each expansion arm.

Filed: 1983-02-25
Abstract: PURPOSE:To keep always an operating frequency constant automatically by adjusting an output setter in accordance with the deviation of frequency between the operating frequency and a frequency setter when a water wheel and a generator are disconnected from the system and are operated. CONSTITUTION:When the water wheel and the generator are disconnected from the system, a switching device 16 disconnects an external driving device 11 and an output setter 10 from each other and connects the deviation of frequency between a frequency detector 1 and a frequency setter 2 and the output setter 10 by a system-side breaker 15.

Title: Semiconductor element for detecting radiation
Inventor: NAGANO KENJI
IPC: G01T1/24
Filed: 1988-02-09
Abstract: PURPOSE:To measure neutrons at high sensitivity by implanting boron containing <10>B in higher concentration than that of <10>B present in nature into a radiation detection region as an impurity. CONSTITUTION:Boron containing <10>B in higher concentration than that of <10>B present in nature is implanted as an impurity into a radiation detecting region. That is, after an N-type impurity region 2 is formed on a main face on which radioactive ray of a P-type semiconductor substrate 1 made of silicon containing the boron <10>B in higher concentration than that of <10>B present in nature is incident as an impurity, a P-type impurity region 3 containing boron containing <10>B in higher concentration than that of <10>B present in nature is formed on the main face. Accordingly, thermal neutron incident on the region 3 is absorbed to the <10>B, and a nuclear reaction occurs thereby to radiate alpha-particles having strong ionization. Thus, holes or electrons generated in the substrate 1 through which the particles are penetrated are gathered and can be externally read as a signal. In this manner, the thermal neutron can be measured at high sensitivity.

Title: Optical head of magnetooptic memory
Inventor: OOTA YOSHINORI
IPC: G11B11/10
Filed: 1984-02-20
Abstract: PURPOSE:To reproduce signals with high S/N and low noise characteristics by reflecting the light, which is transmitted through the first and the second 1/4 wavelength plates, on the surface of a photomagnetic disc and providing a photodetector which detects optical waves emitted from a polarizing element and detecting the phase of the photoelectric conversion signal of the photodetector. CONSTITUTION:Light 20 transmitted through the second 1/4 wavelength plate 8 becomes a rotating linearly polarized light rotating with an angular frequency OMEGA and is irradiated to a photomagnetic disc 2. The reflected light from the photomagnetic disc 2 is made incident on the second 1/4 wavelength plate 8 again and is converted to the rotating linearly polarized light to two orthogonal linearly polarized lights. Polarization of only optical wave components which go back on a going path 16 is rotated at 90 deg., and they are diffracted. A relative wavelength shift between two wavelengths is 2OMEGA, and the rotating linear polarized light which goes back on a path 14 and rotates with an angular frequency 2OMEGA is led to a photodetector 11. Since a slight polarized light diffraction effect due to the photomagnetic disc is detected by electric phase comparison, the quantity of received light is large, and variance of the light source causes no noise to improve the S/N.

Abstract: PURPOSE: To prevent the fall of volume efficiency with the raise of the oil discharge pressure of an balance piston and the heating of suction gas by discharge oil avoided by returning the discharge oil of a bearing and the piston to a compressing chamber in suction operation.  
     CONSTITUTION: When rotors 1 and 2 rotate, a compressing chamber 9 increases in volume to suck gas. At this time, the radial suction port 6 formed in its circumferential wall 3 is closed and only the axial suction port 7 formed in its suction side wall 4 is open. A discharge oil return hole 10 is so provided in the circumferential wall 8 of a casing as to open in the chamber 9 in that condition. The discharge oil of a bearing and the discharge of the operating oil of a balance piston is returned to the chamber 9 through the hole 10 so that the raise of oil discharge pressure above suction pressure, the obstruction of the operation of the piston and the heating of suction gas by discharge oil are avoided. The fall of volume efficiency can thus be prevented.
