Title: Preventive method for adhesion of marine creature in intake channel
Inventor: ISHIKAWA TAKASHI
IPC: E02B1/00
Filed: 1993-08-04
Abstract: PURPOSE:To prevent adhesion of marine creatures in an intake channel at a low cost. CONSTITUTION:Marine creatures stick to an intake channel because spawn of marine creatures stick to the boundary layer and grow up. From this view point, a pair of water collection plates 3 are arranged so as to make an opened- angle-form against the stream direction, in the intake channel 1 which is always fully filled with water and further, the collection plates are slowly reciprocated. Since a part of water stream flows at a high speed on the boundary layer due to the water collection plate 3, the boundary layer is broken. Accordingly, the marine creatures are prevented from sticking and since the energy of water flow is utilized, the operation cost is low.

IPC: F02M51/08
Filed: 1984-10-11
Abstract: PURPOSE:To always stabilize the motion of a valve element to aim at enhancing a stable accuracy of metering the amount of injection fuel and an every-time stability of fuel atomization, by providing the valve element therein with a limiting part for limiting the seating attitude of the valve element with respect to a valve seat. CONSTITUTION:Even if a valve element 16 is moved variously in association with the attraction and separation of an armature iron core 15, a columnar shape section 16a is held in a through-hole 20. Accordingly, the seating attitude of the valve element 16 with respect to a valve seat 22 is such that there is no rotational motion since the motion of the valve element 16 is limited by the mated slide surfaces of the through hole 20 and the columnar shape section 16a. Further, the attitude of the valve element is always uniform, and the final rest position of the movable iron core 15 after completion of its operation is always parallel with a stationary iron core 4 and the spacer 9. Further, the valve element 16 moves along the center axis of the columnar shape section 16a, and therefore, the movable core 15 is always held in parallel with the stationary iron core 14 and the spacer 9 even during the operation of attraction and separation.

Filed: 1989-08-21
Abstract: PURPOSE:To prevent a laser output from being lowered until impurity concentration is saturated at the initial stage of laser operation by providing a laser gas purifying device, and encapsulating impurity gas produced during laser oscillation in a discharge tube beforehand. CONSTITUTION:A laser oscillator 1 is supplied with given mixing ratio laser gas from a laser gas supply device 2 and a given amount of impurity from an impurity addition device 4.
