Title: Shape of bow of chunky ship
Inventor: TAKAHASHI TAKESHI
IPC: B63B1/06
Filed: 1980-09-24
Abstract: PURPOSE: To reduce the resistance increase and pitching on wavy water, by providing the hull of a ship with a flat part which horizontally extends outward from the main part of the hull at the bow under the waterline and by making the width of the flat part larger than the waterline width of the main part of the ship body.  
     CONSTITUTION: The full of a chunky ship is provided with a flat part 13 under the waterline at the bow so that the flat part almost horizontally extends outward from the main part 11 of the hull. The width of the flat part 13 is made larger than that of the longitudinal section 11a of the main hull part 11. The displacement by the bow part near the waterline is reduced so that the decrease in the displacement is cancelled by the submerged flat part 13. This results in reducing the resistance increase and pitching on wavy water.

Title: Reflection type liquid crystal display device and its manufacture
Inventor: SUZUKI YUKIE
IPC: G02F1/1335
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of ruggedness on a liquid crystal display member formed on the upper layer of a reflection plate while ruggedness optimumly designed about the reflection characteristic of the reflection plate is being maintained by arranging a film having a flat surface on the light incidence surface of the reflection plate. SOLUTION: Since the flatened film 15 having the flat surface is arranged on the upper layer of the reflection plate 14, the reflection plate 14 improved at its parallax and having optimized ruggedness is held to prevent the picture quality of a display picture from being deteriorated due to defect orientation. Although the ruggedness of the reflection plate 14 having optimized optical design is held, the surface of an orienation film 16 is flatened without forming ruggedness by forming the flatened film 15 on the upper layer of the plate 14. Thereby the dispersion of rubbing due to the ruggedness of the plate 14 can be removed, the generation of defective orientation can be prevented and an image of high picture quality can be displayed.  In addition, the thickness of a liquid crystal layer is not dispersed, retardation Δn.d (d: thickness of liquid crystal layer) is also fixed, contrast is improved, and an image of high picture quality can be displayed.

Abstract: PURPOSE:To drive a rotating magnetic head with low voltage and low power consumption and with low cost and high reliability, by supporting the head via an elastic substance of high permeability, absorbing the body through an electromagnetic coil and correcting the position of the head. CONSTITUTION:When power is applied to electromagnetic coils 14, 15, attracting force is produced between yokes 12, 13 and high permeability members 16, 17 (or, elastic plates 18, 19 made of high permeability member) and the plates 18, 19 go upward. Thus, operating heads 1, 2 fitted at the tip of elastic plates 3, 4 go upward. In this case, the reference current is given to the current in the electromagnetic coil and the current is increased or decreased, allowing to control the displacement upward or downward from the reference position. Thus, the head can be driven with low voltage and power consumption and with low cost and high reliability.

Title: Ventilation device
Inventor: ISHIZUKA ICHIRO
IPC: F24F7/06
Filed: 1985-06-19
Abstract: PURPOSE:To make it possible to ventilate selected rooms with a large volume of air and allow the ventilation of multiple rooms with a single unit of ventilation appliance by opening the damper for the selected rooms only by manipulating the forced priority switch while dampers for other rooms are closed, and operating the ventilation appliance at a high setting. CONSTITUTION:When the forced priority switch 8 is made ON, the relay 7 is actuated to close the normally opened contact 7b to cause the motor 2 to be electrified directly at its high setting for 'HIGH' operation. At the same time, the circuit to dampers 5a, 5b, 5c for respective rooms connected to the normally closed contact 7a is interrupted, but, the damper 5a receives the power supply from the circuit that directly supplies the power to the damper 5a from the normally opened 7b, bypassing the switch 6a. As a result, the damper 5a is opened while other dampers 5b, 5c remain closed. Since the ventilation appliance 1 is being operated at high setting, and only the damper 5a for the room having the forced priority switch 8 is opened while the dampers 5b, 5c for other rooms are closed, the ventilation of the room having the forced priority switch 8 being made ON only becomes possible.

Filed: 1988-05-30
Abstract: PURPOSE:To obtain highly efficient braking control function by controlling a brake system in such a way that the four-wheel independent control, the rear wheels select-low control or the front and diagonal wheels low control is selected according to the coefficient of friction with the road surface and the amount of the slippage at the rear wheels. CONSTITUTION:When the turning speed of wheels is reduced by the brake application, an electronic control circuit 10 calculates the estimated wheel speed, the coefficient mu of friction with the road surface and the sum SR of the slip ratio at the rear wheels according to the wheel speeds detected by sensors S1 to S4, and compares the results with related reference values mu0 and THR. If mu>mu0 and SR<mu, the entire wheels are controlled independently, if mu>mu0 and SR>THR, or mu<mu0 and SR<THR, the front wheels FL and FR are controlled independently and the rear wheels RL and RR are placed under the select-low control. If mu<mu0 and SR>THR, the front wheels FL and FR are placed under the diagonal select-low control and the rear wheels RL and RR are under the select-low control. As a result the problems of reduction in direction stability and shortage in braking force are dissolved so that the highly efficient braking control may be executed.
