Abstract: PURPOSE:To reduce water quantity which leaks from a drainage box to the outside by disposing a packing at the entrance of the drainage box to drain water leaking from a guide plate which forms a flow passage in a water turbine into the drainage box as non-pressurized water. CONSTITUTION:A boss 3 for fixing a bearing 5 is fixed at the jointed part of both upper and lower casings 1, 2 by a rib 4 which also serves as an exit/ entrance guide vane. Besides, the inner ring 7 of the runner 6 is fitted to the bearing 5. With this constitution, a rotating cylinder 8 and an outer ring 18 are disposed at the outside of the runner 6. Moreover, the inner peripheral surface of the rotating cylinder 8 is sealed by a packing 12 inside a packing box 11 which is fixed inside the drainage box 10 formed by both the upper and lower casings 1, 2 and a guide plate 9. Moreover, a belt 15 is fitted to the outer ring 18 to transmit the rotation of the runner 6 to a motor. It is thus possible to drain water leaking from a guide plate 9 which forms a flow passage inside a water turbine as non-pressurized water, reducing water leaking from the drainage box 10.

Inventor: KUWABARA TAKASHI
IPC: G06F11/18
Filed: 1992-08-27
Abstract: PURPOSE:To constitute the dual CPU so that an A system CPU and a B system CPU contend with each other for the right of using of a command bus on equal terms, and also, without using an arbitrating circuit, etc. CONSTITUTION:Each CPU 1, 2 tries to output bus request signals 21, 22, respectively to the other CPU extending from the time point when it is started to use a bus 3 to the time point when use of the bus is finished. In this regard, its output is executed by discriminating non-existence of the bus request signal of the other system, and also, an actual use start of the bus 3 is executed by discriminating non-existence of the bus request signal of the other system again after a prescribed time (several CPU cycles) elapses, after the bus request signal is outputted once. In this regard, at the time of this repeated discrimination, when the bus request signal of the other system exists, a prescribed one of two CPUs 1, 2 annihilates the bus request signal in its output, and the other CPU discriminates this annihilation and starts to use the bus 3.

Inventor: TANNO MASAYUKI
IPC: G02B6/30
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring method in which an optical waveguide without any face droop is selected by a method wherein a core edge at the optical waveguide is irradiated with a laser beam, an optical fiber is moved in parallel along the core edge and it is measured that the cycle of a change in the intensity of its reflected light is at a specific value or higher. SOLUTION: For example, a laser beam at a wavelength of 1.31μm from a laser light source 2 is incident on an optical fiber 32 via a wavelength-independent bidirectional optical coupler (WIC) 4, a core edge 8 at an optical waveguide 1 is irradiated from the tip of the optical fiber 32 whose tip is brought close to 0.1 to 10μm from the core edge 8, its reflected light is coupled to the optical fiber 32, it is incident on an optical power meter 5 via the WIC 4, and the intensity of the reflected light is measured. Then, while the optical fiber 32 is moved in parallel along the core edge by every very small distance from the surface 9 of the optical waveguide 1, the intensity of the reflected light is measured, and the relationship between a distance and the intensity of the reflected light is found.  Then, it is confirmed that the cycle width of the intensity of the reflected light is at 30μm or higher and that the face droop of the core edge does not exist. When the optical waveguide is evaluated by this method, the optical waveguide without any face droop can be selected with good efficiency and easily.

Title: Medium-positioning mechanism
Inventor: KINOTA MANABU
IPC: G06Q40/02
Filed: 1985-10-14
Abstract: PURPOSE:To prevent a medium from skewing, by providing a part for discriminating the kind of a medium inserted, providing a medium-detecting part at a guide part for moving the medium to one side, and moving the inserted medium according to the kind of the medium until a side end part of the medium is detected by the medium- detecting part. CONSTITUTION:With a slip 5 inserted into an inserting port 1, the inserted medium is discriminated as the slip 5 due to a low contact pressure detected by a sensor S3, and a corresponding feed quantity is read from a feed quantity memory 12. A feed- controlling part 13 drives a feeding mechanism 7 in correspondence with the read feed quantity, and the slip 5 is fed toward a guide 1b by a laterally moving plate 71. When a side end part of the slip 5 depresses leaf springs 8a, 8b and both sensors S4, S6 are shielded by shielding plates 80a, 80b, the feed-controlling part 13 stops driving the feeding mechanism 7 in response to a signal from an AND circuit 14. Then, a stopper 6 is opened, and the slip 5 is fed in by feeding-in rollers R1-R4. When a passbook is inserted, a high contact pressure is detected by the sensor S3, and feeding is stopped in response to detection by the sensors S4, S5. Accordingly, the medium to be inserted can be inserted easily and normally, and jamming and skew printing can be prevented from occurring.
