Title: Controlling device of reactivity in reactor
Inventor: KUDO FUMIO
IPC: G21C9/02
Filed: 1990-10-19
Abstract: PURPOSE:To enable control of a reactor output for the situation wherein a rise in temperature is abnormal, by a method wherein an absorber for reactivity control suspended from the fore ends of movable arms is lowered by a thermal expansion difference between tension rods 7 and a rod which is a strength member. CONSTITUTION:When the temperature of a reactor coolant rises due to some cause, the fore ends of movable arms 4 are lowered with pins 6 operating as fulcrums, by a thermal expansion difference between a rod 1 and tension rods 7 of which a thermal expansion coefficient is small. Therefore a distance between pulleys 12 and 13 is made small, an absorber 14 gears with this through wires 16 and moves downward, i.e., into a core. Thereby an output of the core is limited. On the occasion, the amount of movement (amount of lowering) is set to be proportional to the distance between the pulleys 12 and 13, the number of winds of the wires 16, the rise in the temperature and the thermal expansion difference between the rod 1 and the tension rods 7 at the time of a rated operation. When the temperature of the coolant returns to the state of the rated operation, the absorber 14 made to move downward with the rise in the temperature returns to the original position automatically by a reverse operation.

Title: Revolution detector
Inventor: OGAWA NAOKI
IPC: G01C19/5607
Filed: 1988-11-09
Abstract: PURPOSE:To obtain an accurate signal with a smaller detection error corresponding to the angular velocity by making a vibrating plate to vibrate normally in the thickness direction which is provided on a tuning fork, and rotating the device making the axis of a rod as the center. CONSTITUTION:A twist detector 3 and the tuning fork are arranged at the center part of the rod 5 provided along a Z-axis. The tuning fork is furnished with the vibrating plate 15 which is formed with a U-shape in the manner of bending a thin- sheet stated metal plate, and the vibrating plate 15 is supported with the rod 5 penetrating through the center part. When the vibrating plate 15 provided in the tuning fork is made to vibrate normally in the thickness direction and the device is rotated making the axis of the rod 5, i.e. Z-axis as the center, a Coriolis' force is exerted to the vibrating plate 15 in the axis direction orthogonally with the axis of the vibration in accordance with the angular velocity of the vibrating plate 15 at that time. As this force is exerted in the direction to make the tuning fork to move rotationally around the axis of the rod 5, the tuning fork is vibrated in the direction to rotate against the rod 5. The accurate signal corresponding to the angular velocity of the device is obtained accordingly by detecting the twisting force to exert between the rod 5 and the vibrating plate 15.

IPC: H01L27/148
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To improve sensitivity of a solid-state image sensing device with a transfer electrode of a plurality of phases without increasing propagation delay of a transfer electrode of an uppermost layer.

Title: Combustion equipment
Inventor: IWAMURA KAZUYUKI
IPC: F23D14/14
Filed: 1985-12-17
Abstract: PURPOSE:To reduce the amount of NOx to be generated by lowering the temperature of flame as well as prevent the occurrence of backward flame by providing a metal net with flame pores coated with a far-infrared rays-radiating paint at the outside face of a burner in a combustor burning a combustible mixed gas. CONSTITUTION:A fuel and air jetted from a fuel nozzle 15 and an air jet nozzle 16 are mixed in a vaporizing cylinder 8 heated to form a mixed gas. The mixed gas comes into the burner head 4 and ignited on the outer surface through the internal air holes of the head 4 made of a sintered porous material to form flame on the surfaces of the a metal net 6 with flame holes. Since the sintered porous material has countless air holes, uniform, short, and stable flame is formed over the whole burning surfaced 17 from strong combustion to weak combustion. Also, since the metal net 6 is applied with a far-infrared rays- radiating paint, the radiation of heat is accelerated to suppress the rise of temperature of the metal net 6 and thereby to lower the temperature of flame. The amounts of NOx to be generated during the combustion period can thus be greatly reduced.

Title: Light diffusing plate
Inventor: YANO SHUJI
IPC: B32B7/02
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To make light transmissivity high and to improve the surface luminance of a surface light source device by making the refractive index of a particulate different between the surface part and the inside of its own and making the difference of the refractive index occurring on a boundary between transparent resin and the particulates small. SOLUTION: This light diffusing plate 1 is constituted by forming a light diffusing layer 6 consisting of the transparent resin 6a and the particulates 6b on the surface of a base plate sheet 7. The refractive index of the particulate 6b is made different between the surface part and the inside, so that the difference of the refractive index occurring on the boundary between the transparent resin 6a and the particulates 6b is made small. After emitted light from the light emitting surface of a light transmission plate is diffused by the plate 1, it is condensed by a light condensing sheet so as to irradiate a liquid crystal display screen.  Since the refractive index of the surface of the particulate 6b is different from that of the inside thereof, the boundary reflection between the particulates 6b and the transparent resin 6a is restrained in the case the light passes the plate 1, and the reflection loss of the light is restrained, thereby improving the light transmissivity by as much as the loss of the boundary reflection.

IPC: G11B20/14
Filed: 1994-11-17
Abstract: PURPOSE: To constitute a PLL circuit so as not to be locked in at a pseudo stability point. CONSTITUTION: Respective reproducing signals of data of a data recording part and address data of a address part are obtained and outputs in which waveforms of these reproducing signals are shaped are supplied to a waveform discriminating circuit 22 and a PLL circuit 20 and a waveform processing is performed based on a clock CK outputted from the PLL circuit. A start/stop type variable oscillator 24 is provided in the PLL circuit. A waveform-shaped output and the envelope detection signal of the reproducing signal are supplied to a shift register 36 and a start/stop pulse corresponding to an envelope output is generated.  Since the oscillation of the variable oscillator is stopped in a period when the start/stop pulse is obtained and when the register 36 is reversed, the oscillator oscillates in synchronization with the data of the reproducing signal, the phase changing range of a phase comparison output becomes narrower and the PLL circuit is made not to be locked in at the pseudo stability point.
