摘要： PURPOSE: To provide a drum rotor for an impulse steam engine including blades locked in longitudinal grooves and an impulse steam engine including said rotor. CONSTITUTION: A drum rotor for an impulse steam engine includes blade wheels constituted by blades whose roots 8 are provided with dovetails and are locked in grooves formed in a rotor 6. The grooves are longitudinal over at least a portion of the rotor 6. The roots 8 of the blades of a blade wheel 10 are separated from the roots 8 of the blades of an adjacent blade wheel 10 by spacers 12. Preferably, a partition plate 15 is an integral member. Thus, an optimum filling of the grooves is effected for better interconnection of the caps of the blades.

摘要： PURPOSE: To generate a zero cross of an electric current even in any environment, and extinguish an arc by connecting a circuit breaker having large breaking force and a circuit breaker which is small in breaking force but has a means to increase arc voltage, in series to each other. CONSTITUTION: One circuit breaker 100 has large breaking force, and the other circuit breaker 200 is small in breaking force but has a means to increase arc voltage by drawing out an arc. These circuit breakers are simultaneously operated, or the breaker 100 is operated slightly later than the circuit breaker 200. The circuit breaker 100 is a publicly known automatic blowing-out type sulfur hexafluoride circuit breaker small in operation energy, and exhibits excellent breaking force at electric current zero cross time. When the circuit breaker 200 is opened, the arc elongates, and its resistance and the arc voltage increase, and the circuit breaker 100 opened simultaneously when a zero cross of an electric current is generated or by delaying several milliseconds, reliably breaks an electric current.

摘要： PURPOSE: To swage a blank by carrying out pressure application to a blank of a tubular thimble inserted into a cylindrical core from the end face of a block made of an elastomer, having a ring-like cross-section shape, and arranged in the surrounding of the blank and decreasing the inner diameter. CONSTITUTION: A tubular blank 1 of a thimble of a contact finger made of a material having high conductivity and elasticity comprises parallel and vertical slots and a ring 3 with durability to an arc. The blank 1 is so positioned in the surrounding of a cylindrical core 10 with approximately same length and diameter as those of the blank as to bring the ring 3 into contact with the end part of the core. A block 5 having a ring like cross-section shape and made of an elastomer material is arranged in the circumference of the blank 1 and pressure application to the blank is carried out from the end face through a thrust washer 11 and a metal top block 8. Consequently, the inner diameter of the block 5 can be decreased as to have a desirous slot width and the blank 1 can be swaged.

摘要： PURPOSE: To simplify manufacture of an insulating gas automatic blast-type series arc-type breaker, by comprising a secondary arc contact generating the pressure for assisting the opening of a breaker inside the volume, and installing all electric contacts outside the volume. CONSTITUTION: In an engagement position, the electric current passes through a contact 4, tubes 8A-8-8B, a finger 13, a flange 12 and a tube 11. When the short-circuit current flows, a driving tube 6 is moved to the right, the contact 4 and 8A are separated, and the current is switched to arc contacts 3 and 7A. Further the finger 13 and the tube 8B are also switched to the contacts 25, 26. The tube 6 is further moved, the contacts 3A, 7A, and 25, 26 are almost simultaneously separated, while arcing there between, but the secondary arc as the latter heats the gas in a volume V2, so that the pressure is increased to act on a piston 30, thereby the opening drive is assisted. An one-way valve 18 is closed, to assist the blowing of the insulating gas in the volume V1 to the primary arc as the former.

摘要： PURPOSE: To make high-sensitivity measurement by penetrating a bottom section with the strands of a fluorescent optical fiber in a base to form a symmetrical loop. CONSTITUTION: When a circuit breaker is opened by the drive of a drive rod 16, a moving arc contact piece 7 is kept in no contact with a fixed arc contact piece 5, and an arc is generated. The light wave is transmitted via a tubular member 14, and most of high-temperature gas is released through openings 13, 15. The light passes through the small-diameter hole 35 of a plate 3, and the high-temperature gas cannot enter a support columnar body 17 due to the small diameter. The side face of an optical fiber 25 absorbs the light, the light is absorbed over the whole length of tens of cm of the optical fiber 25, and high-sensitivity measurement can be made. Since the optical fiber 25 is symmetric, individual strands can receive the same quantity of light, the same amplifiers 32, 33 are used to calibrate a device, and the device can be accurately positioned. Amplifiers different in sensitivity are selected to classify the arc into two intensity ranges after the device is once adjusted.
