Filed: 1978-03-24
Abstract: PURPOSE: To reduce the power of auxiliary machinery in the halt of the plant by pumping-up sealing steam from a condenser by a water pump 20 having a small capacity in the stop state of the plant.  
     CONSTITUTION: In the stop state of the plant, a portion of the sealing steam supplied to a packing part 3 from an auxiliary steam system flows into a condenser 4 in low pressure, and the rest sealing steam is supplied to a grand condenser 6 through a grand exhaust pipe 5 from outside the packing part 3. The sealing steam which flows into a condenser 4 is pumped-up by a small capacity water pump, and through the cooling system 21, exchanges heat with the cooling water which passes through cooling narrow pipes 19 and forms condensed water to be stored in a hot well. The cooling water having performed heat-exchange is discharged to a drainage canal through a return system 22. Thus, the retention of vacuum in the condenser is enabled without operating a circulation water pump 8 which necessitates large power consumption.

Filed: 1990-02-13
Abstract: PURPOSE:To impart excellent heat resistance, chemical resistance and impact resistance by constituting a resin composition of a PPS resin to which deionizing treatment is applied and an epoxy group-containing olefinic copolymer in a specific wt. ratio. CONSTITUTION:A PPS resin composition prepared by adding 0 - 200pts.wt. of an inorg. filler to 100pts.wt. of a resin component consisting of 95 - 60wt.% of a polyphenylene sulfide (PPS) resin to which deionizing treatment is applied and 5 - 40wt.% of an epoxy group-containing olefinic copolymer is used as a main constituent. The PPS resin to which no deionizing treatment is applied is inferior to the compatibulity with epoxy group-containing polyolefin and appearance inferiority or the marked lowering of impact resistance is generated. When the compounding amount of the PPS resin is 95wt.% or more, below moldability is lowered and, when said compounding amount is 60wt.% or less, heat resistance or chemical resistance is damaged. When a fibrous and/or granular inorg. reinforcing agent is compounded with 100pts.wt. of the PPS resin and the epoxy group-containing olefinic copolymer in total within the range not exceeding 200pts.wt., strength, rigidity, heat resistance or dimensional stability can be enhanced.

Title: Method of taking out cable strand
Inventor: WATANABE YUUSAKU
IPC: B65H59/04
Filed: 1980-03-18
Abstract: PURPOSE: To prevent a strand within a reel from slack automatically and positively by taking out forcibly the strand while exerting rotational torque to the reel in a direction opposite to that of taking out the strand.  
     CONSTITUTION: Rotational torque of a reel 23 in the direction 11 of taking up a strand is controllably held by an unreeler 8 automatically. When the rotational frequency of a hydraulic motor 15 is set to a predetermined level by a control 16, the predetermined rotational torque of a reel 23 in the direction of taking up the strand is given by the unrealer 8. This torque appears as back tension to the strand being taken up near an outlet of the reel 23, and the amount of the torque can be changed by the switching operation of the unreeler 8. Thus, no slack is produced since the rotational torque 11 is always given by the reel 23.

Title: Optical input type switching device
Inventor: NAKAMURA TAKURO
IPC: H03K17/78
Filed: 1990-02-13
Abstract: PURPOSE:To realize an optical input type switching device capable of self-hold action by providing a storage function of a photoelectric conversion output to a post-stage of a photodetector section and providing a photoelectric conversion output reverse flow block function to the photodetector section. CONSTITUTION:When a light enters a photodetector section 1 of an optical input type switching device, an electromotive force is generated therein. A FET 2 is energized by the electromotive force. An electric charge is stored in a stray capacitor C (acting like a storage function) between a gate G and a source S of the FET 2. When no light enters to the photodetector section 1, the electromotive force (photoelectric conversion output) is lost. As soon as the optical input is lost, when the RET 2 is turned off, a discharge control circuit 4 is immediately operated to discharge the charge stored in the stray capacitor C and the drain D and the source S are interrupted. When the FET 2 is kept on even after the loss of the optical input, the discharge control circuit 4 is not operated. In this case, since a diode 3 of reverse polarity is connected to the photodetector section 1, the drain D and the source S are conductive.
