Abstract: PURPOSE: To improve the condition of steam flowing into a turbine to a superheated one and eliminate the necessity of installing a large shield in a turbine system. CONSTITUTION: A steam pipe 5 connected to a reactor pressure vessel 1 is equipped with a heat exchanger 22. A primary system of the heat exchanger 22 is connected to the steam pipe 5, and a water pipe 29 on the primary system of the heat exchanger 22 is connected to a feedwater pipe 7. A steam pipe 24 on a secondary system of the heat exchanger 22 is connected to a high-pressure steam turbine 11. A steam heater 27 is installed between the high-pressure steam turbine 11 and a low-pressure steam turbine 14, and a bypass pipe 44 which branches off from the steam pipe 24 on the secondary system is connected to the steam heater 27. The steam from the low-pressure steam turbine 14 turns to condensate, which flows from a low-pressure feedwater heater 18 through a water pipe 23 on the secondary system into the heat exchanger 22.  Consequently, the condensate on the side of the secondary system turns from subcool through saturated steam and water to steam entirely and is further superheated. The steam flowing into the turbine side turns to superheated steam which does not contain moisture, which improves the efficiency of the turbine.

Title: Magnetic disk device
Inventor: WAKATSUKI SHIGETO
IPC: G11B17/32
Filed: 1989-12-04
Abstract: PURPOSE:To secure the commencement of suction of a magnetic disk without providing a pressing pad by providing a slantwise moving means for slanting a suction plate in order to gradually spread out a gap between the suction plate and the magnetic disk along the rotating direction of the magnetic disk at the time of starting turning the magnetic disk. CONSTITUTION:The disk device is provided with the slantwise moving means (iron piece and suction solenoid) 7 and 8 for slanting the suction plate 2 in order to gradually spread out the gap between the suction plate 2 and the magnetic disk 3 along the rotating direction 14 of the magnetic disk 3 at the time of starting rotating the magnetic disk 3. Consequently, even if an projecting amt. of the magnetic head 1 against the suction plate 2 is large, the distance between the magnetic disk 3 and the surface of the suction plate 2 can be reduced, thus facilitating the occurrence of negative pressure. Then, since a negative pressure generating effect owing to expansion of an airflow path by a slant of this suction plate is added, the suction force is increased. By this method, without providing a pressing pad, the magnetic disk 3 can securely by started to be sucked by the suction plate.

Title: Inertial sliding type starter
Inventor: ARAKI TSUYOSHI
IPC: F02N15/06
Filed: 1993-12-16
Abstract: PURPOSE:To provide the inertial sliding type starter which can realize quick advance rising while an increase in shock is being prevented when a pinion gear is advance stopped. CONSTITUTION:Though a sliding contact section 9 fixed to a housing is slidably in contact with a rotating section (one-way clutch) 4 at least when the rotating section starts rotating, the advancement of the rotating section permits friction force with the rotating section to be attenuated. As a result, when an output shaft 2 and the rotating section 4 starts rotating, though high advancing acceleration is given to the rotating section 4 through a helical spline groove 21 because the sliding contact section 9 restrains the rotation of the rotating section 4, rotation resistance based on friction between the sliding contact section 9 and the rotating section 4 is reduced before the advancement of a pinion gear 6 is suspended, the resistance is decreased by that much that the advancing force of the rotating section 4 is reduced, and shock at the time when the advancement of the rotating section 4 is suspended is thereby lessened by that much.
