摘要:
The present invention provides a thin film transistor, wherein the semiconductor channel region is patterned. Gate electrodes 102, gate insulating film 103, source electrodes 104, and drain electrodes 105 are formed on a glass substrate 101. A patterned insulating film is formed thereon, and a part of the film in the region 110 on the gate electrode is removed. An organic semiconductor film is formed thereon by vapor deposition. The organic semiconductor film 107 in the region 110, where the patterned insulating film is removed, becomes a channel region, and is separated from the organic semiconductor film 108 on the patterned insulating film 106. Therefore, the organic semiconductor channel region is patterned to have the same size as the gate electrode. In accordance with the present invention, a thin film transistor, wherein the semiconductor region is patterned precisely, becomes available.

A reflective-type display device having a light modulating layer, including a host dispersed with light scatterers, which is held between two transparent electrodes; and a light absorbing layer disposed in back of the light modulating layer. The size of each light scatterer or the nearest distance between the adjacent light scatterers is nearly equivalent to the wavelength of incident light at least in two-dimensional directions. The refractive index ratio relative to incident light between the light scatterers and host is changed from 1 to 1.5 or more depending on the magnitude of a voltage applied across the electrodes.

A liquid crystal layer composing a liquid crystal display apparatus is formed by being laminated with a plurality of single particle layers of liquid crystal micro-capsules having a uniform size and being arranged in a two-dimensional crystal array, the liquid crystal micro-capsule being formed by cladding a liquid crystal droplet with a medium having a constant thickness. The liquid crystal micro-capsule is formed by being cladded with a medium composed of gelatine and gum arabic. Further, the single particle layer has a filling medium for making the surface flat and filling the gaps among the liquid crystal micro-capsules. The filling medium is composed of gelatine and gum arabic.

A control system for an automatic transmission includes a first frictional engagement element and a second frictional engagement element; and a first hydraulic servo for controlling the application/release of the first frictional engagement element and a second hydraulic servo for controlling the application/release of the second frictional engagement element. A regulator valve regulates the oil pressure to the first hydraulic servo. A signal pressure is applied to the regulator valve to establish a predetermined gear stage by switching the applied/released states of the first frictional engagement element and the second frictional engagement element by feeding/releasing oil pressure to/from the first hydraulic servo and the second hydraulic servo. The regulator valve includes a valve member having: a first pressure receiving area to which is applied the feed pressure to the first hydraulic servo as a feedback pressure in a first direction; a second pressure receiving area to which is applied the signal pressure in a second direction opposite the first direction; a fourth pressure receiving area to which is applied the feed pressure to the second hydraulic servo in the first direction, in a shift wherein the first frictional engagement element is released while the second frictional-engagement element is applied; and a third pressure receiving area to which is applied the signal pressure in the second direction, for regulation of the oil pressure only during a shift.

A shift control system is provided for an automatic transmission having, connected in series, a secondary shifting unit, capable of being shifted between a high speed stage and a low speed stage, and a primary shifting unit which provides plural speed stages including a reverse speed stage. The secondary shifting unit can be set to the high speed stage upon a shift into reverse. The shift control system is equipped with a reverse range detector for detecting a shift from neutral to reverse range, a vehicle stop detector for detecting that vehicle is stopped, and a high speed stage command device for setting the secondary shifting unit at the high speed stage when, subsequent to a shift of the primary shifting unit into reverse, the vehicle is determined by a signal from the vehicle stop detector to have substantially stopped.

A controller of an automatic transmission provides gear changes with optimum gear change characteristics under any traveling conditions. The controller of the automatic transmission of the present invention includes an input torque detector for determining input torque to the transmission, an inertia torque estimator for estimating an inertia torque corresponding to the rate of change of rotary speed of a rotary member during a gear change, input torque corrector for calculating a required operating torque by adding the input torque and the inertia torque and an operating pressure controller for controlling operating pressure to correspond to the required operating torque. The operating pressure corresponding to the necessary engagement torque is supplied to a hydraulic servo, to effect a gear change, irrespective throttle opening and driving speed and irrespective of whether the gear change is made step by step or jumped.

A control system is provided for servo hydraulic pressure in an automatic transmission. Upon downshifting, one of first and second frictional engagement devices is released while the other is engaged. A directional control valve is provided to feed or drain servo hydraulic pressure to selectively engage or release the first and second devices. The hydraulic pressure is regulated by a pressure regulator under the control of an electronic control unit. Detectors are also provided to determine input rotation and torque, respectively. The regulator is interposed between the directional control valve and the engaged device. The regulator is controlled to maintain the servo hydraulic pressure at a predetermined value under the control of the electronic control unit until predetermined input rotation is detected and then to gradually raise the servo hydraulic pressure under the control of the electronic control on the basis of the value of input torque.

摘要:
A control system in an automatic transmission for controlling the change-over of the three speed change patterns which are a speed change pattern having a cross gear ratio on a low speed side, a speed change pattern having a cross gear ratio on a high speed side and a speed change pattern having a normal gear ratio. According to this controlling system, when one of the three speed change pattern is selected based one a throttle opening and a vehicle speed, and when it is judged that the gear shift from a speed range in the present speed change pattern to a speed range in the selected speed change pattern falls under on of prohibited conditions, e.g., requiring engagement and/or disengagement of three or more frictional engaging elements for the gear shift, the gear shift is performed using a temporary speed change pattern (including the present speed change pattern) including a speed range not falling under the prohibited conditions. Thereafter, the pattern selection is repeated and the change-over between speed change pattern is performed under a gear shift condition not falling under the prohibited conditions.
