Filed: 1988-11-28
Abstract: PURPOSE:To prevent the slackening of a magnetic tape drawn out to a front face by displacing tape guide member(s) and/or tape pad(s) between a position of pressurizing contact with each other and their separating position. CONSTITUTION:When an upper half is opened, a pad supporting body 93 of a tape guide mechanism 25 on the side of a supply reel is turned to be displaced in the direction of C by a spring 94, and the tape pad 92 and a guide pole 90 are separated by a prescribed distance, and then a guide roller 101 of a tape guide mechanism 26 on the side of a take-up reel is energized in the direction of D by a spring 106, so that the guide roller 101 is separated from a tape guide 100, and hence the magnetic tape can easily be passed through these gaps respectively. Then, when the upper half is closed, the pad supporting body 93 of the tape guide mechanism 25 is rotatively displaced, so that a tape pad 92 fitted to the tip is brought into pressurized contact with the guide pole 90 to hold the magnetic tape between them, and then the guide roller 101 of the tape guide mechanism 26 approaches the tape guide 100, thus preventing the magnetic tape from slackening.

Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To provide a nondestructive test device of concrete capable of detecting precisely and surely an internal crack of a concrete product. SOLUTION: An external force applied to an ALC board 1 by a hammer 2 for generating a hammering sound is detected by an exciting force sensor 11, and the ratio thereof to an external force reference value is determined by a ratio computing unit 15. The hammering sound generated on the ALC board 1 is detected by a microphone 3, and separated into time series signals in each frequency zone by an analog BPF 5, and rectified and instantaneous maximum values in each frequency zone are extracted by a peak hold 7. The maximum values are corrected based on the ratio calculated by the ratio computing unit 15, and compared with a vibration reference value set up beforehand by a comparator 9.  When the result is out of the prescribed relation, comparison result signals are issued, and if the number of the comparison result signals is, for example, three or more, an alarm unit 18 gives the alarm. As the maximum values of the time series signals in each of the plural frequency zones are extracted and compared, reliability of the determination is improved.

Title: Recirculation pump system with built-in nuclear reactor
Inventor: NAKAMURA AKIRA
IPC: G21C15/243
Filed: 1991-11-18
Abstract: PURPOSE:To prevent a recirculation pump from being abruptly lowered in revolution, and thereby enable cooling a furnace core to be kept on by disposing a cooling water pump in the pipe line for a cooling water supply connected to the pump motor section of recirculation pump system with a built-in nuclear reactor. CONSTITUTION:A cooling water pump 33 driven by a steam turbine is, for example, disposed in the cooling water pipe line 31 of a heat exchanger 30, and is connected to a cooling water inlet port 32 provided for the lower section of a motor casing 8. When one of power supplies for the pump motor 6 of recirculation pump 2 with a built-in nuclear reactor is cut off, the pump impeller 7 of the pump 2 is lowered in revolution. Since cooling water pressurized by the pump 33 is fed into the pump 2, an auxiliary impeller 19 is driven by cooling water. By this constitution, the pump 2 is neither abruptly lowered in revolution, nor suspended. This configuration thereby dies not result in passage resistance which impairs the other flow of refrigerant by the pump 2 normally operated, any fuel rod will never increase in temperature.

Title: Electric double layer capacitor
Inventor: HIRAHARA SATOSHI
IPC: H01G11/24
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To obtain durability at the time of applying a high voltage and increase energy density, by optimizing material for adjusting the natural potential of activated carbon electrodes and its loadings, and setting the potentials of a positive pole and a negative pole at the time of applying the maximum voltage to be in the range that decomposition due to oxidation or reducing reaction of non-aqueous electrolyte is not generated. SOLUTION: In an electric double layer capacitor, non-aqueous solution is used as electrolyte and activated carbon electrodes are used as both poles. When electrodes whose natural potential is reduced by setting the amount of Li in both activated carbon electrodes to be 0.02-2 wt.% are used, the adjustment in a potential range that decomposition of the non-aqueous electrolyte is hardly generated is enabled, by setting the potential of a positive pole side in the electrolyte at the time of applying the maximum allowable voltage to the activated carbon electrodes to be 3.5-4.2 V (to Lm/Li+ ), and by setting the potential of a negative pole side to be 0.1-0.8 V (to Li/Li+ ). In order to increase the capacitance of the electric double layer capacitor, it is preferable that activated carbon whose specific surface area is large is used as activated carbon before Li is introduced.

Title: Liquid fuel supplier by spraying
Inventor: YASUDA HIROFUMI
IPC: F23D11/30
Filed: 1989-11-20
Abstract: PURPOSE:To keep to the minimum the amount of fuel drops falling to the front face of a fuel shielding plate and the amount of fuel flying towards it and supplying the fuel surely and accutately with a small variation in the control of the fuel supply with spraying by forming the circumferential section of the fuel passage hole of the fuel shielding plate tapered internally towards a fuel passage hole. CONSTITUTION:A fuel shielding plate 60 is formed to have its circumferential section tapered towards the fuel passage hole 61 in its center. Namely the fuel shielding plate 60 is formed to have its fuel passage hole 61 project towards a spray nozzle 1 like a truncated cone. With this formation the collision angle of the sprayed fuel that is to be cut by the inner wall face 60a of the fuel shielding plate at the circumferential section of the fuel passage hole 61 becomes small and fuel flying is prevented, and the fuel that is cut moves smoothly along the inner wall face 60a to the outer circumferential section. And, the taper toward the inside of the inner wall face 60a constitutes a kind of 'return point' and it becomes difficult for the fuel that is once shielded to go over the fuel passage hole 61. By the way, since the outer wall face 60b of the fuel shielding plate at the circumferential section of the fuel passage hole 61 is tapered towards inside, it can dodge without difficulty the sprayed fuel Q passing through the fuel passage hole 61.
