Title: Measuring for temperature and pressure of coolant in nuclear reactor
Inventor: NISHIWAKI NOBUHIKO
IPC: G21C17/02
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To measure the temperature of a coolant by measuring the pressure of the coolant within a pipe line and also the acoustic velocity thereof by the emission of ultrasonic wave to a plurality of points of the coolant. SOLUTION: Ultrasonic oscillators P1, P2, P'1, P'2 are provided on the outer surfaces of primary and secondary circulating passages 3, 6 in order to measure the temperature of a coolant carried in the pipes 3, 6. The melting temperature and acoustic velocity of a fluid having a fixed pressure have a fixed relation, and this is applicable to the temperature and acoustic velocity of Na in fused state. The pressure can be measured by sticking a metal oil on the wall surface of a pipe line and measuring the ultrasonic wave reflected by the boundary surface between the foil and the wall surface.  On the basis of the measurement principle of 'when materials A, B differed in acoustic impedance are perfectly in contact to each other, ultrasonic wave is partially reflected by the contact surface, and the reflectance is determined depending on the impedance values of both the materials A, B, the corresponding pressure can be measured by measuring the reflected quantity of ultrasonic wave. The acoustic velocity can be measured according to the principle of 'a fluid is suddenly reduced in acoustic velocity at about the melting point when the temperature is raised'. Thus, the temperature of the coolant can be measured.

Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To provide an aeronautical beacon lamp equipped with a color filter providing a stable color of light by a simple manufacturing process even if it has a rounded shape, and having a chromaticity range of the color of light prevented from being deviated by a change in an ambient temperature. SOLUTION: In this aeronautical beacon lamp 1, an incandescent lamp 4 as a light source is attached to a fixed member 2b of a lamp body 2 by means of a light-source support part 5, while a globe 3, a color filter 60a, and a glass member 60b are attached to a fixed member 2a of the lamp body 2. The glass member 60b is formed of transparent glass of a rounded shape while the color filter 60a is formed into a cap shape covering the glass member 60b by using a colored silicone rubber member. The colored silicone rubber member 60a can be simply formed into a color filter providing stable color of light without precisely mixing color materials that affect variations in color of light, and is characterized by producing no color deviations by a change in an ambient temperature.  Thus, the color filter 60a can be formed providing stable color of light without a color material mixed therein irrespective of its shape, and therefore the aeronautical beacon lamp 1 can be provided that has better light emission performance and lower manufacturing cost than a conventional one.

Title: Base driving system for power transistor
Inventor: TAMURA YASUHARU
IPC: H02M3/00
Filed: 1988-06-01
Abstract: PURPOSE:To simplify the circuit and to reduce the cost while keeping the equal function to that of a conventional system by using an unregulated voltage for a positive voltage of a power transistor(TR) base driving circuit of the collector catch system (CCD system) and adopting a regulated voltage for the negative voltage of the circuit. CONSTITUTION:A forward voltage of a DC-DC converter type power supply circuit is adopted for a positive voltage (P) and a regulated flyback voltage is adopted for a negative voltage (N). Since the negative voltage (N) of the CCD system base drive circuit is regulated by obtaining the flyback voltage of the DC-DC converter type power supply circuit, a constant diode and a diode for stabilizing the base voltage are able to be eliminated from a conventional base drive circuit. Moreover, the positive voltage (P) of the base drive circuit is obtained from the forward voltage of the DC-DC converter type power supply circuit proportional to an output voltage of a DC power supply C<+>-C<->.

Title: Phase and frequency comparator
Inventor: MIZUGUCHI HIROSHI
IPC: H03K5/26
Filed: 1981-08-27
Abstract: PURPOSE:To improve synchronism acquisition characteristics by providing a phase comparator with a frequency discriminating function. CONSTITUTION:When a reference phase signal PR arrives, the 1st trigger pulse generating circuit 100 generates a pulse and a down counter 400 performs counting operation. This counting operation is carried on until the level at the output terminal 600c of a phase detector 600 goes up to 1 and the output of the counter 400 goes down to 0. When the counter 400 outputs 0, a clock pulse is not supplied from a gate circuit 700 any more. While the output level of the phase detector 600 is 1, on the other hand, the level of the set terminal 400b of the counter 400 is still 1, so the counter 400 is not set. Therefore, when the frequency of the input signal is not coincident, the output is held at a minimum or maximum according to the frequency of a phase detection signal is high or low for the frequency of the reference phase signal, so not only the phase difference between both the signals, but also the frequency difference is discriminated.

Title: Repeat arithmetical operation device
Inventor: MIYOSHI AKIRA
IPC: G06F7/487
Filed: 1994-06-17
Abstract: PURPOSE:To quickly execute the repeat multiplication of normalized floating- point numbers with a small amount of hardware. CONSTITUTION:A mantissa XMk satisfying 1<=XMk<2 is supplied to a mantissa processing part to execute the repeat multiplication of normalized floating-point binaries Xk (k=0,..., (m)) expressed by P=X0XX1XX2X...XXm. The mantissa processing part is so constituted that the product expressed by a redundant binary number is stored in a register 15 and is fed back to a multiplier 13 without being converted into a binary. A shifter 14 for right one-digit shift processing is inserted between the multiplier 13 and the register 15. A converter 16 successively converts the redundant binary stored in the register 15 into a binary and supplies a shift extent signal S1 corresponding to the conversion result to the shifter 14. In this case, S1 is set to 0 if the digit two digits higher than the decimal point of the binary obtained by conversion is 0, but S1 is set to one if it is one.

Title: Two-cycle internal combustion engine
Inventor: OOYAMA KAZUO
IPC: F02D13/02
Filed: 1982-08-03
Abstract: PURPOSE:To increase the charging efficiency of mixture by deviding an exhaust port in two, upper and lower ports. CONSTITUTION:Since a two-cycle internal combustion engine is subject to reflecting negative pressure waves of exhaust only when the upper half of the exhaust port is open on the up stroke of a piston, it is not necessary to control the whole of the exhaust port for opening and closing with a rotary valve. Therefore, the exhaust port is divided at least in two, upper 31 and lower 32 ports and a rotary valve 41 is provided for the upper port 31, while the lower port 32 is controlled for its opening and closing through the reciprocating movement of a piston 5. The upper and lower sides of both exhaust ports 31 and 32 are formed in gentle curves and their four corners are rounded thereby smoothly pushing back a piston ring 6 which is going to project when positioned at the exhaust ports 31 and 32. As the exhaust rotary valve 41 carries out the opening and closing of only the upper half exhaust port 31, the capacity of a recess P1 between the valve 41 and the port 31 becomes less than half of the conventional type reducing the quantity of staying new air thereby improving the fuel cost and the output power.
