Title: Wave power propulsion vessel
Inventor: NISHIKAWA KOICHI
IPC: B63H19/02
Filed: 1987-11-25
Abstract: PURPOSE:To obtain a wave power propulsion vessel which is excellent in buoyancy absorption efficiency by promoting the oscillation motion of the water in a duct below a hull buoyancy chamber so as to take out wave power as output of an air chamber upper face and rotating a pusher through an air turbine so as to propel the vessel. CONSTITUTION:A horizontal duct 2 is attached to below a long and narrow buoyancy chamber 1, and this opens in a stern and this is long in the horizontal direction and a hollow duct. The inside is filled with water, and this is bent upward at a right angle in the front end of the buoyancy chamber 1 so as to form an air chamber 3. The air chamber 3 is located in front of the buoyancy chamber 1, and large relative wave height is generated in the air chamber 3 by the pitching of a vessel so as to compress and suck the air of a upper face. This air force passes through a duct 4 and becomes the high speed rotation of a turbine shaft by an air turbine 5 and is decelerated through a speed reducer 6 so as to rotate a propeller 8. This pushing force of the propeller 8 advances hull through a propeller holding hardware 9.

IPC: F16H59/72
Filed: 1988-11-24
Abstract: PURPOSE:To prevent any response delay from occurring by overshooting a command value from a desired command value as much as a quantity conformed to oil temperature when this command value for a hydraulic controlling solenoid is changed, and afterward putting it back to the desired command value. CONSTITUTION:When a controlling computer changes a command value for a hydraulic controlling solenoid, for example, when a driving current value I1 is changed to a desired value I2, it overshoots the command value temporarily from the desired command value I2 and then puts it back to this value I2. Here a degree of this overshoot, namely, an overshoot rate or overshoot time is set according to oil temperature being detected by an oil temperature detecting means. Thus, hydraulic pressure is always controllable with proper response speed.

Title: Method for decreasing residual stress of metallic strip
Inventor: WATANABE TERUO
IPC: B21B1/22
Filed: 1985-12-28
Abstract: PURPOSE:To apply a desired residual stress to a metallic strip which is slit to a prescribed width according to working conditions by subjecting said strip to skin pass rolling with a pair of rolls which have different moduli of elasticity and face each other. CONSTITUTION:An edge drop hardly arises on the sintered hard alloy roll side but the edge drop and resultant deformation arise on the high speed steel roll side in the 1st pass of skin pass rolling in which the sintered hard alloy rolls and high speed steel rolls are combined. The weak residual stress having the tendency to bend outward arises in the 2nd pass of skin pass rolling in which the high speed steel rolls are combined. The desired residual stress can be thus be applied to the strip according to the working conditions. The execution of the 2nd skin pass rolling by combining the rolls consisting of different materials is also possible.
