Title: Reactor having integral type pressure vessel construction
Inventor: KAWATA TOKUO
IPC: G21C1/20
Filed: 1989-03-16
Abstract: PURPOSE:To simplify constitution and to improve the safety in the event of an accident by partitioning a heavy water moderator and a coolant only by a pressure pipe thereby facilitating the heat transfer from a fuel assembly through the coolant to the heavy water moderator. CONSTITUTION:The fuel assembly is loaded in the pressure pipe and the outside surface of the pressure pipe comes into direct contact with the heavy water moderator in a calandria tank 22. The heavy water moderator is, therefore, operated usually under approximately the same conditions as the conditions for the coolant. If an outflow-of- coolant accident (e.g. dislodgment of a recirculation pump 26) happens, the pressure of the coolant system decreases rapidly and the pressure difference generates, then the rupture disc 46 breaks out. The heavy water moderator becomes steam, enters the coolant system and is released to the outside of a pressure vessel 24 while cooling the fuel assembly. The core cooling by the heavy water moderator is started in this way. A heat removal mode is switched to auxiliary machinery cooling by an auxiliary heat exchanger 44 from the feed water heating by a main heat exchanger 42 in a heavy water cooling system 32 and the removal of decay heat is executed by the moderator system. Since the pump of the cooling system 32 is kept run at all times, the safe and reliability are enhanced.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a filament sewing thread having a fluff such as a spun yarn by which the interlacing treatment can be carried out at a high speed of >=100 m/min while retaining a high strength. SOLUTION: One or plural multifilament yarns Y having a first twist applied thereto in a first twisting step are doubled, reciprocated and wound around a guide. The yarns in the forward passage are alternately interlaced with the yarns in the return passage to thereby apply twisting and squeezing thereto and carry out a fluffing processing. At this time, heat treatment is conducted so as to provide a yarn temperature of Tg or above and the softening point or below just before the interlacing treatment. The resultant yarn is then subjected to the final twisting in the final twisting step.

Title: Temperature-type expansion valve
Inventor: KURODA SHIGEAKI
IPC: F25B41/06
Filed: 1982-04-21
Abstract: PURPOSE:To expand the usage range of flow control by using a bar member made of a shape memory alloy as a valve rod or by fitting a valve seat to a coil member made of the shape memory alloy so as to form the valve seat movably. CONSTITUTION:A bar member 12a made of a shape memory alloy is inserted in the middle of a valve rod 12. A refrigerant enters from below an expansion valve and flows in an arrow direction through a clearance between the lower section of a valve body 6 and a valve seat 3. At this time, if the temperature of a heat sensitive section 4 is elevated, the pressure of a space 1a is raised, the center of a diaphragm 1 is moved downward, this movement forces the valve body 6 to move through the valve rod 12, the clearance between the lower section of the valve body 6 and the valve seat 3 is made larger, and the refrigerant flow is increased. If the temperature of the heat sensitive section 4 is lowered, the clearance between the valve body and valve seat is made smaller on the contrary, and the flow is decreased.

Title: Quadrature frequency division multiplex communication system
Inventor: TAKAHASHI YASUO
IPC: H04L27/26
Filed: 1995-03-24
Abstract: PURPOSE: To provide an OFDM communication system capable of preventing erroneous frequency synchronization. CONSTITUTION: In a demodulator for quadrature demodulating OFDM modulation signals using the codes of high autocorrelation along a frequency axis as reference signals for erroneous frequency synchronization prevention, transforming them to the signals of the frequency axis by an FFT processing and demultiplexing multiplexed signals at a prescribed timing, a frequency deviation is calculated from a rotation amount on the phase plane of FFT processing output in a frequency error detection circuit 27 and a carrier wave frequency for quadrature demodulation is controlled so as to turn the frequency deviation to '0.' Then, the reference signals for the erroneous frequency synchronization prevention are separated from the FFT processing output in a reference signal separation circuit 28,  code correlation with the reference signals from a reference signal generation circuit 29 is detected in a correlation detection circuit 30 and whether or not synchronization is performed by a correct frequency is judged by a correlation peak position. The processing of frequency demapping is shifted corresponding to a judged result and thus, correct signals are surely demodulated.

Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To produce the subject new compound capable of retaining surface modifying actions such as hydrophility, antimicrobial activities or dew condensation preventing properties for a long period by including sulfonate group and a fluoroalkyl group therein. SOLUTION: This compound is represented by formula I (R is H or methyl; M is Li, Na or K; (n) is 1-6; Rf is a 1-20C fluoroalkyl), e.g. a compound represented by formula II. When R is H, a metallic salt of a succinic acid monoester (e.g. potassium salt of monoallyl succiniate) is reacted with a fluorine iodide [Rf-(CH2 )n -I] to provide a compound represented by formula III, which is then dissolved in a mixed solvent, etc., of water with ethanol. A metallic hydrogensulfite (e.g. sodium hydrogensulfite) is subsequently added to afford the objective compound. When R is methyl, the allyl group of the monoallyl succinate can be replaced with a group represented by CH2 =CCH3 CH2 to thereby afford the objective compound in the similar method for production. The resultant compound is capable of forming a homopolymer of itself and further a copolymer thereof with other vinyl monomers.

Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To reduce the amplitude of torsional vibration in a crankshaft to be produced at the time of motoring an internal combustion engine by an electric motor mechanically connected to the crankshaft of this engine via damper as well as to make it quickly pass through a revolution area where a resonance phenomenon is induced. SOLUTION: When an engine is started, first of all, the on-off timing of an inlet valve 152 of this engine 150 is controlled to delay the ignition timing, thereby motoring the engine by a motor MG1 to be mechanically connected to a crankshaft 156 via a damper 157. When this engine 150 exceeds an area where its speed causes a resonance phenomenon, the on-off timing of the inlet valve 152 is put back to the ordinary timing, and control over the fuel supply and ignition of the engine 150 is stated. If the on-off timing of the inlet valve 152 is controlled to delay its ignition timing, an effective compression ratio of the engine 150 becomes reduced, so that the engine 150 is able to be smoothly rotated and driven, and thus the amplitude of torsional vibration in the crankshaft 156 is reducible.
