Title: Liquid crystal display device
Inventor: OTANI AKINARI
IPC: G02F1/139
Filed: 1988-01-14
Abstract: PURPOSE:To always obtain an image of high quality by dividing one picture element to one or plural first areas and one or plural second areas and constituting a device so that axes of polarization of first and second polarizing plates are parallel with each other in the first area but are orthogonal to each other in the second area. CONSTITUTION:The device is so constitute that axes of polarization of a first polarizing plate 203a and a second polarizing plate 203 are parallel with each other in the first area, namely, a normally black N.B. area 105a and axes of polarization of a first polarizing plate 203b and the second polarizing plate 203 are orthogonal to each other in the second area, namely, a normally white N.W. area 105b. By this constitution, opposite voltage-transmittance characteri stics of N.B. and N.W. areas in a minute area are seen as an average value on the whole of a screen by human eyes. Thus, white part and white/black inversion are not sensed though the voltage applied to liquid crystal is not adjusted in accordance with the change of the visual field, and an image of good tone and high quality is always obtained.

IPC: F24H1/00
Filed: 1988-01-14
Abstract: PURPOSE:To simplify the structure of the device and to accomplish a water level control with good accuracy by driving an electrically-driven type switching valve on the basis of a signal from at least one of a water level sensor and switching means. CONSTITUTION:A control circuit 4 generates an output on the basis of an output of a water level sensor 5 to actuate a drive circuit including a power amplifier and the like for supplying power to actuate a switching valve 122. The switching valve 122 which has been closed up to that time is opened and water is supplied into a water storage tank 1 through a hot water supply pipe 120. When, in accordance with the water supply, the float 5b of the water level sensor 5 rises up, the output of the sensor 5 is turned off at a predetermined water level. In this case, power supply to the switching valve 122 is stopped, the switching valve 122 is closed, and hot water supply from a supply hot water heating unit A is interrupted. Upon this occasion, in a case where the control circuit 4 does not interrupt the output even if the defined water level is exceeded due to the fault of the water level sensor 5, switching means 8 is driven and opened by a float 6 and power supply to the switching valve 122 is interrupted, and hence the switching valve 122 is closed.

Title: Controller for automatic transmission
Inventor: SANO AKIHIKO
IPC: F16H61/04
Filed: 1988-01-13
Abstract: PURPOSE:To prevent dry blow-up from occurring by detecting a variation in an actual gear ratio from input-output shaft rotational frequency, and for a period when this variation is within the specified range, maintaining a friction factor, varying from the clamp side to the release side, in a clamped state. CONSTITUTION:An automatic transmission control unit 19 selectively clamps and releases a frictional engaging element 8 of a gear shifting mechanism 7 according to a specified shift characteristic curve on the basis of each signal out of a throttle sensor 14 and a car speed sensor 15 and performs a speed change. In this case, a variation in an actual gear ratio is calculated from rotational frequency Nt of an input shaft 5 to be detected by a turbine speed sensor 16 and rotational frequency of an output shaft 6 or a car speed signal, and for a period when this variation is within the both upper and lower gear ratio reference values, a friction factor of the frictional engaging mechanism 8, varying from the clamp side to the release side, is maintained in a clamped state. Thus, supposing that engine output tries to start up to a high output range by foot operation from power-on, any blow-up of an engine can be prevented from occurring.

Title: Device for forcing gear onto shaft end of motor
Inventor: TAMURA YOZO
IPC: F16H55/17
Filed: 1988-01-18
Abstract: PURPOSE:To arrange a dimension between a motor case and gear with high accuracy for reducing dispersion thereof by applying a preload between the motor case and a shaft and fixing it to a lift block and plate so that a forcing force is applied only to the shaft to force the gear onto the shaft. CONSTITUTION:When a lift block 13 is lowered while a thrust load corresponding to the dead load of a holding die 15 is applied between a motor case 3b and a motor shaft 3a, a temporary clamp pin 16 is first operated by a cam plate 18 to brake the holding die 15 with a force acting on the side of holding die 15. When the lift block 13 is further lowered, a wedge 19 is operated by a cam plate 21 so that the upper portion of holding die 15 contacts a slant surface 19a to fill mechanically the gap and prevent the holding die 15 from upward displacement. Thus, a motor 3 is locked by the lift block 13 on a motor mounting plate 14 and the motor shaft 3a is forced into a gear on a gear bed 22 to complete the forcing in a fixed position of the plate 14 abutting against the gear bed 22. Thus, the finishing dimension between the motor case 3b and gear 2 can be arranged with high accuracy.

Abstract: PURPOSE: To control the amount of dissolved oxygen in the aeration tank for raising the utilizing rate of oxygen by introducing pure oxygen through a pathway separated from the flow of ventilating and stirring air in the clarification of waste water by sending pure oxygen into the mixture of activated sludge and waste water in the aeration tank.  
     CONSTITUTION: Air from an air blowing device 11 is sent upwardly in the form of bubbles into the mixture 10 of activated sludge and waste water inside the aeration tank 1 to stir the mixture 10. On the other hand, pure oxygen is injected from the pure oxygen blowing device 21 into the water 20 to be treated in the oxygen dissolution tank 2 to saturate the water 20 with oxygen. When the concentration of dissolved oxygen in the mixture 10 inside the tank 1 is detected, and the value is read out by an automatic control meter 4 and reduced to less than the set value, a needle valve 6 connected to a control box 5 is opened to introduce the oxygen-saturated water 20 into the mixture 10 to increase the amount of dissolved oxygen to the set value. When the set value is reached, the meter 3 detects it, the valve 6 is closed, and the amount of dissolved oxygen is automatically controlled to the set value.

Filed: 1985-01-18
Abstract: PURPOSE:To attain the automatic character disposition for plotting by calculating the degree of superposition between a polygon already set at a plotting position within a CPU and a polygon set newly and deciding the position of the new polygon excluding said superposition part. CONSTITUTION:For an automatic production system of disposition line diagram, both character string and symbol data are defined by an oblong polygon 26 and supplied to a CPU2 from an input device 1. The polygon 26 is set at the position of the plotting coordinates as a rectangle having the minimum size that can cover a single symbol 31 or a series of character strings 30. The CPU2 carries out the nearby search processing and checks the presence of a polygon which has possibly the superposition on the periphery of a newly set polygon. The check processing is performed for superposition after the periphery search processing is through with all existing polygons. Then the position of the new polygon is shifted and the result of the superposition check is delivered to an output device 3 after correction of the character string data. In such a way, the characters can be disposed automatically with no superposition of character strings, symbols, etc.
