Title: Reactor water control method for bwr plant, low radioactive concentration reactor water bwr plant and fuel cladding tube for bwr
Inventor: UETAKE NAOTO
IPC: G21C17/022
Filed: 1993-07-01
Abstract: PURPOSE:To allow efficient reduction of radioactivity in reactor water even if fuel rods, to which metal ions scarcely adhere, are loaded by accelerating adhesion of crud to a newly loaded fuel and stopping the adhering operation of clad when a predetermined target adhesion is reached. CONSTITUTION:When a pressure vessel 10 of reactor is loaded with a new Zr liner fuel 13 and the operation is started, an electrolytic iron injector 14 is operated simultaneously to produce iron crud. Electrolytic iron is injected 15 into supply water while sustaining the injection concentration at 2ppb and the injection is stopped when the total quantity of iron reaches 5X10<5>g/cm<2> the sum of surface area of all newly loaded fuel rods. Furthermore, an anion-exchange resin in a desalting condenser 5 is partially rendered to Na type and the condensate is passed. The pH of supply water is then increased to 7-9 and the operation is sustained for a while even after the injection of iron crud is interrupted. Water supply to a resin tower is then stopped and switching is made to other resin tower and a cycle of operation is ended while lowering the pH below 7. Consequently, metal ions adhere well to the fuel and the radioactivity in the reactor water is reduced.

Title: Amplifying device
Inventor: UENAKA SUSUMU
IPC: H03F1/32
Filed: 1983-09-05
Abstract: PURPOSE:To output rated outputs corresponding to a high power source voltage and a low power source voltage with operations of both power source voltages when a sound volume is maximum, by switching feedback resistances of an amplifier in accordance with power source voltages. CONSTITUTION:When the power source voltage is low as a battery or the like, the base current is not flowed to a transistor TR6 because the Zener voltage of a Zener diode 8 is set to a value higher than this power source voltage, and the TR6 is turned off, and a voltage gain GV of the amplifier is equal to 1+R4/R3 where resistance values of resistances 3 and 4 are denoted as R3 and R4. Meanwhile, when the power source voltage is high, the Zener current is flowed to the Zener diode 8 to make the TR6 conductive, and a resistance 5 is inserted in parallel to the resistance 3, and therefore, the voltage gain GV is equal to 1+R4/ R3+R4/R5 where R5 is the resistance value of the resistance 5. Since voltage gains suitable for respective power source voltages are set in this manner, prescribed purposes are achieved.

Title: Method and device for inspecting pattern
Inventor: IWATA SATOSHI
IPC: G01N21/956
Filed: 1988-06-30
Abstract: PURPOSE:To surely decide the tapered state of an edge face whether it is normally tapered or reversely tapered by irradiating the tapered section with polarized light from the oblique direction of the tapered section of a pattern and measuring the reflected light beam from the tapered section. CONSTITUTION:When linearly polarized light beam is made incident to the tapered section 3 of a pattern 2, laser light beam 4 is detected after the laser light beam is reflected plural times by a base plate 1 and the tapered section 3. When a visual point is placed on the (n-1)th reflecting point by assuming that the detected light beam is nth-order reflected light beam, the nth-order reflecting surface makes rolling motions against the (n-1)th-order reflected light beam. Namely, the change in the polarized angle of the (n-1)th-order reflected light beam fluctuates proportionally to the change in the tapered angle of the nth-order reflecting surface. Therefore, the polarized angle of the reflected light beam to be detected changes as the tapered angle changes. Thus whether an edge face is normally tapered or reversely tapered can be surely decided.

Title: Insulating transmission circuit
Inventor: SHIOE YASUHIKO
IPC: H04L25/02
Filed: 1979-12-18
Abstract: PURPOSE:To make small the size of transmission circuit, by giving the signal modulating clock pulse with the input signal, to two sets of full-wave rectifying circuits via pulse transformers. CONSTITUTION:With the input terminal 2 fed with the signal S in H level, when the clock pulse CP is fed with the pulse CP at H level, a current flows to the winding of a pulse transformer T1 toward the arrow A and with the pulse CP at L level, the current toward the arrow B flows. No current flows to the pulse transformer T2 in any case. Next, when the signal of L level is fed to the terminal 2, a current flows only to the winding of the transformer T2 alternately. Thus, since the phase control of the clock pulse is made at the primary side of the pulse transformers, no transformer for phase control is required, allowing to constitute the transmission circuit only with two pulse transformers.

Abstract: PURPOSE:To form a curved edge having an appearance being continuous to other part by softening inside by heating a narrow zone approximately along the part to be cut and forwarding a cutting blade from the outer surface side under the condition that the outer surface side has a higher hardness than the inside. CONSTITUTION:Air for cooling is blown on a molded item 2 under a condition that a tension is applied on the molded item 2 by pulling a clamp 45 in the direction (b). When a cutting blade 15 is forwarded from the outer surface side, as the outer surface 2a has a higher hardness than other part, the outer surface is not cut or broken and pushed down as it is while it is drawn and as the result, a resin of the inside 2b moves to the surrounding. Part of the resin of the inside 2b easily tend to move to the uncut part 44 and to form a protuberance, which can be prevented to occur by applying the tension. When the cutting blade is furthermore forwarded, the uncut part 44 and the outer surface part 2a are curvedly deformed while an appearance being continuous to other part is kept and are cut under a condition that a curved edge 62 is formed.

Abstract: PROBLEM TO BE SOLVED: To widen the material value limit range of construction material to be used, to facilitate dimensional control and to improve assemblability by heating a toner cap before press-fit engagement and press-fitting and engaging it in a toner filling port in a state in which its temperature is raised. SOLUTION: A toner unit J is constituted by covering the toner filling port with the toner cap 11f after it is filled with toner from the toner filling port. The toner cap 11f is formed of the construction material such as polyethylene or polypropylene or the like, and it is press-fit in the toner filling port provided on a toner frame body 11 after heating so that it may be prevented from falling off. The toner cap 11f is warmed by using a heating means such as a drier by the time just before the press-fit engagement and the warm toner cap 11f is press-fit and engaged in the toner filling port. At such a time, the temperature of the heated toner cap 11f is >=35 deg.C and <=60 deg.C. Thus, the upper limit value of the rigidity of the usable construction material is improved and the press- fitting time is shortened.

Title: Epoxy resin composition
Inventor: SUGAWARA TOSHIO
IPC: C08G59/40
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To obtain a composition having a low viscosity, a short curing time and a long pot life which are essential characteristics of a resin for impregnating an electric insulating coil or the like by specifying an initial viscosity and an increase in viscosity during storage of a one pack-type epoxy resin composition containing a latent curing agent. SOLUTION: This epoxy resin composition has an initial viscosity of not higher than 1 Pa.s at 25 deg.C and the viscosity reaches two times as high as the initial viscosity not earlier than 120 days when stored at 25 deg.C. Preferably, a liquid epoxy resin employed comprises a resorcinol type epoxy resin as an essential component and cures within 10 min at 150 deg.C. As a latent curing agent can be employed an aromatic sulfonium compound salt or a boron trichloride amine salt. The boron trichloride amine salt gives out an extremely irritating odor necessitating the use of a draft chamber when added to the resin and its dissolution in cresyl glycidyl ether in advance is preferable to destroy the irritating odor practically.

Filed: 1978-12-29
Abstract: PURPOSE:To make antisinging possible with a simple circuit by dividing signals, which come around the hybrid transformer of a subscriber's circuit, into two groups and by mixing them so that they may be cancelled by each other. CONSTITUTION:A part of the service signal sent from telephone set A to the transmission side of hybrid transformer HA of subscriber's circuit LA is leaked to the transmission side of hybrid transformers HB-HN of another telephone set subscriber's circuit, and all of the signal is inputted to mixer circuit M1 assigned to telephone set A through the transmission path of each transmission side and is mixed and is inputted to the receiving side of hybrid transformer HA of telephone set A, and a part of the signal is leaked to the transmission side to constitute a singing loop. When the number of participating subscribers is increased, the quantity of echo is incerased to cause danger of singing. Therefore, input ends for output signals from transformers HA-HN of participating subscriber's circuits are divided into two groups in respective input parts of mixer circuits M1-Mn, and signals inputted to one group are inverted for signals inputted to the other group, and they are mixed. Thus, singing is prevented by cancelling signals coming around by each other.
