Title: Marine screw propeller steering method
Inventor: FUJITA SHOJI
IPC: B63H5/07
Filed: 1985-02-22
Abstract: PURPOSE:To reduce the load imposed on a main engine, by making a water current, containing air bubbles, flow in a main part of a propeller blade an and around the critical revolving speed of a screw propeller, while reducing the extent of propulsive toque of the screw propeller temporarily. CONSTITUTION:When the revolving speed of a screw propeller 3 reaches to the vicinity of critical revolving speed, a compressed gas generator is operated and thereby compressed gas is jetted out of a compressed gas injection nozzle 4. And, a water stream 7 inclusive of this compressed gas flows in a range of 0.5-0.9 times over a rotating diameter D of the propeller blade. This range is equivalent to a main part of the propeller blade as propulsive torque of the screw propeller 3 is largely produced. The compressed gas is jetted out of the compressed gas injection nozzle 4 whereby the water current 7 flowing into this range comprises air bubbles so that fluid density of the water current 7 comes small, thus the propulsive torque becomes reduced.

IPC: C10B39/02
Filed: 1986-02-19
Abstract: PURPOSE:To provide a method capable of operating a winder according to the required time of a carrying device and reducing the power consumption, by controlling the speed of a winder so as to attain the minimum power consumption and, at the same time, completing the winding and unwinding operations within a carrying time of red hot coke. CONSTITUTION:The speed of a winder 11 is controlled by controlling the speed of winding and unwinding of the winder 11 and the speed of travel of a winding truck 13. A drive motor of which the number of the revolutions can be freely varied is used. This drive motor is controlled by signals from a speed control device. Individual speeds with respect to the winder and power consumption are determined by simulation so as to satisfy a condition which completes the operations of the winding, charging, and unwinding by means of the winder 11 within a carrying time of the carrying device 2 and minimizes the waiting time and a condition which minimizes the power consumption with respect to the winder 11. The cycle time of the winder 11, the speeds of winding and unwinding and the speed of travel are determined based on the data thus obtd.

Title: Optical information recording carrier
Inventor: IIDA TETSUYA
IPC: G11B7/2534
Filed: 1989-02-14
Abstract: PURPOSE:To obtain the optical information recording carrier which is decreased in the influence of the defective part between a substrate and a transfer layer on laser light by forming the transfer layer having the film thickness which satisfies prescribed conditions. CONSTITUTION:The optical disk consists of the transparent substrate 11 and the transparent transfer layer 12, a recording layer 13 and a protective layer 14 successively laminated on the substrate 11. This transfer layer 12 has the film thickness (h) to satisfy an equation h>=(l/K)cottheta. In the equation, (l) is the average radius of the opaque region to shield the laser light to be projected to the critical face between the transfer layer and the recording layer; K<2> is the area ratio of the area of the opaque region to the section of the laser light to be projected at the critical face; theta denotes the angle formed by the normal line of the reflecting surface of the recording layer and the outer edge of the focused laser light to be projected. The transfer layer 12 is formed thicker than the film thickness of the general transfer layer 2 and the substrate 1 is formed correspondingly thinner, by which the defect 5 at the critical face between the substrate and the transfer layer is parted from the pit P surface of the reflecting layer. The influence of the defective part on the laser light is decreased in this way.

Title: Multi-window control system in half duplex communication system
Inventor: YASUNAGA HIROSHI
IPC: G06F13/00
Filed: 1991-02-06
Abstract: PURPOSE:To utilize a multi-window system without waiting an input by substituting output operation for input operation from a host side computer system to a terminal side computer system without allowing an application program to be conscious of the substitution. CONSTITUTION:Output operation is substituted for input operation from the host side computer system 1 to the terminal side computer system 6 without allowing the application program(AP) 5 to be conscious of the substitution. The transmission of a response from the system 6 to the system 1 is executed simultaneously with the transmission of a brake signal from the system 6 at the time of completing each input operation of an operator. Consequently an window input waiting problem can be eliminated and an window environment having excellent operability can be attained. In addition, an existing AP 5 can be used as it is.

Title: Simplified x-y table
Inventor: SAWADA YUZO
IPC: B23Q1/62
Filed: 1987-02-18
Abstract: PURPOSE:To simplify construction of a stage driving gear in an XY table, by constituting the table forming in a continuous state an X axis loop and a Y axis loop by a single winding unit and switching the operative condition of a control rotary unit by a brake means. CONSTITUTION:When an X axis loop 12 is controlled, forcedly stopping rotation of a control rotary unit 17 by a brake means 19, a winding unit 11 is unmovably restricted on the peripheral surface of the control rotary unit 17. Under this condition, if a motor 21 is started, tensile force acts on a fixed end of either the control rotary unit 17 or an arm 3 of the winding unit 11, moving the arm 3 in that direction. If the motor 21 switches its driving rotary direction, the arm 3 moves in a reverse direction. On the other hand, when Y axis loops 13A, 13B are controlled, releasing the brake means 19, the control rotary unit 17 is switched to a condition that it can rotate in the same direction to the winding unit 11. Under this condition, if the motor 21 is started, tensile force acts on a loop guide 16 on a stage 5 so as to pull out one of the loops to the side of the X axis loop 12, and the loop guide 16 is moved.
