Title: Method for powering hydrofoil boat take off and arrangement therefor
Inventor: SAITO YASUO
IPC: B63B39/06
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To power and smooth a takeoff of a hydrofoil boat by obtaining an optimum trim tab angle from takeoff performance information at which the hull resistance at an approximate takeoff speed of the boat becomes a minimum under a condition of an actual boat being loaded and controlling the trim tab angle to the optimum trim tab angle. SOLUTION: Boat speed information of a boat speed sensor 10 is sent to an optimum trim tab angle calculation device 11. Takeoff performance data obtained from model tests or trial runs is stored in a memory device 12 in advance as takeoff performance information of the actual boat sorted by loaded conditions of the actual boat. Information from the memory device 12 and an input device 13 to which data of a boat weight and an initial trim are inputted is sent out to the optimum trim tab angle calculation device 11. The optimum trim tab angle calculation device 11 calculates the optimum trim tab angle at an approximate takeoff boat speed based on the actual boat speed, takeoff performance information, and loaded condition. The calculated result is sent to a servo-actuator 9 to control the trim tab 7 to the optimum trim tab angle.

Filed: 1983-05-30
Abstract: PURPOSE:To send out liquid by a method wherein a sollar heat collecting part is provided in an expanding and contracting vessel to heat the liquid in the vessel and the vessel is expanded and contracted by the change of a shape memory alloy in accordance with the change of temperature. CONSTITUTION:The pump 5 is provided with the expanding and contracting vessel 6, whose peripheral wall 6c is made of bellows-shaped shape memory alloy, and the sollar heat collecting section 7 provided on the upper surface of the pump. When the solar heat collecting section 7 receives the sunshine and water therein becomes hot-water, the vessel 6 is brought into expanded condition due to the deformation of the peripheral wall 6c consisting of the shape memory alloy and cool water flows into the vessel through an entrance port by the effect of a non-return valve 8. The shape memory alloy is contracted again by the inflow of the cool water and the vessel 6 is contracted again also and the water in the vessel 6 is pushed out of the outlet port of the vessel to the side of the heat collector by the effect of the non-return valve 9.

Abstract: PURPOSE: To prevent unsatisfactory cleaning and toner leakage from occurring due to a very small step on a photoreceptor by making a photoreceptive layer area longer than the length obtained by adding the abutting area of a cleaning member and the abutting area of a sealing member. CONSTITUTION: In a photoreceptor drum 7, an organic photoconductive layer (photoreceptive layer) 7b is formed on the outer peripheral surface of an aluminum cylinder 7a functioning as a conductive base substance. The photoreceptive layer area 7b1 of the photoreceptive layer 7b is formed to be longer than the length obtained by adding the abutting area 7b2 of a cleaning blade 9a removing toner left after transfer on the drum 7 and the abutting area 7b3 of the sealing member 9e preventing the toner from being leaked from both ends of the blade 9a to both ends in the longitudinal direction of the drum. Thus, the cleaning member 9a and the sealing member 9e are prevented from coming into contact with an uneven photoreceptive layer area 7b4 at the end of the photoreceptive layer caused by drop of liquid or nonuniform peeling in the case of forming the photoreceptive layer.

Title: Surface combustion burner and heat exchanger utilizing this burner
Inventor: IGARASHI KAZU
IPC: F24H9/00
Filed: 1985-05-08
Abstract: PURPOSE:To prevent backfire and make it possible to give surface combustion always in stable state by mounting a cooling box through which a cooling fluid passes at the downstream side of a mixing chamber where a gas and air are mixed to make a premixing gas. CONSTITUTION:A cooling box 10 is provided at the downstream side of a mixing chamber 9, and many through-holes 11 are provided which pass the premixing gas toward a combustion chamber 12. The through-holes 11 are cooled by a fluid that passes through the cooling box 10 to maintain the temperature of the passing premixing gas to a temperature below the ignition temperature. When the amount of supply of the premixing gas is reduced and its speed is lowered in order to lower the combustion temperature at a burner A, the position of ignition which is effected in the combustion chamber 12 moves gradually towards the mixing chamber 9, but the premixing gas passing through the through-holes 11 does not ignite because it is maintained at a temperature below the ignition temperature. Accordingly, there is no fear that backfire occurs in the premixing chamber 9.
