摘要:
A liquid crystal display element, which is installed in a projection-type color liquid crystal display, is provided with the first glass substrate. The first glass substrate is provided with the first micro-lens array on its light-incident side and the second micro-lens array on its light-releasing side. The first micro-lens array converges light beams of respective primary colors onto the vicinity of the light-releasing position on the second micro-lens array. The second micro-lens array makes the incident light beams parallel to each other and releases them from the liquid crystal display element. Thus, even in the case of using a projection lens having a small diameter, it is possible to improve the efficiency of utilization of light. Moreover, this arrangement eliminates the necessity of having to employ a comparatively expensive projection lens with a large diameter, thereby reducing the costs of production.

The projection-type color display device of the invention includes: a white light source; a splitting means for splitting white light emitted from the white light source into a first, a second, and a third beam having respectively different wavelength regions; a modulation means for modulating the first, the second and the third beams; an irradiation means for irradiating the first, the second and the third beams onto a principal surface of the modulation means at respectively different angles; and a projection means for projecting the first, the second and the third beams modulated by the modulation means. In the projection-type color display device, the first beam includes a color beam having a weakest intensity among the beams in three primary colors contained in the white light; and a direction of the first beam incident onto the principal surface of the modulation means is closer to a normal of the principal surface of the modulation means as compared with the second and the third beams.

Particles of a lens coating material for forming a primary film are deposited from a direction toward which the surfaces of the lens prisms of a Fresnel lens face. Next, a light absorbing film is formed, conventionally, by sputtering, on both the lens surfaces on which the previously deposited primary film was formed and on the non-lens surfaces (on which no primary film was formed). This light absorbing film is intended to absorb types of undesirable or "invalid" light (e.g., "flaring light"). Subsequently, the films are removed from only the lens surfaces. Accordingly, a Fresnel lens having "invalid" light absorbing films only on the non-lens surfaces is more easily fabricated within a shorter time and at a reduced cost. Moreover, it is also possible to reduce the generation of "cone" and "rainbow" effects caused by "flaring light" when the Fresnel lens is used as a field lens of a projection-type image display device.

Safety of the distance between vehicles is judged by monitoring whether or not an object other than a front road surface, namely, a preceding vehicle, exists in a predetermined area of the front road surface which is recognized by a picture processing unit used as a sensor for recognizing traffic states of the front road, without recognizing an image of a preceding vehicle having a complicated shape and a plurality of colors of the preceding vehicle by means of picture processing.

A base insulating layer is formed on a suspension body, and write wiring traces and read wiring traces are formed on the base insulating layer. The write wiring trace and the read wiring traces are formed on a body region of the base insulating layer, and the write wiring trace is formed on an auxiliary region of the base insulating layer. The base insulating layer is bent along a bend portion. This causes the write wiring trace to be positioned above the write wiring trace.

An electrode-wiring substrate includes first routing wires (108) made of gate material for forming gate electrode wires (105) and second routing wires (110) made of source material for forming source electrode wires (106). The first routing wires (108) and the second routing wires (110) are arranged alternately so as not to coincide with each other when viewed in plan. The second routing wires (110) are electrically connected to the gate electrode wires (105) via first contact holes (111) and to gate electrode terminals (102) via second contact holes (113).
摘要:
First, second, and third light sources serve to emit light having three primary colors, respectively. The first light source is activated by a first drive pulse which has a first width and which repetitively occurs at a specified frequency. The second light source is activated by a second drive pulse which has a second width and which repetitively occurs at the specified frequency. The third light source is activated by a third drive pulse which has a third width greater than the first and second widths and which repetitively occurs at the specified frequency. Time positions of front edges of the first, second, and third drive pulses are different. The first drive pulse occupies a time range contained in a time range for which the third drive pulse extends. The second drive pulse occupies a time range contained in the time range for which the third drive pulse extends.

A method and apparatus for detecting the quality of combustion in each cylinder of a multi-cylinder internal combustion engine is disclosed. The invention determines a combustion stroke of each cylinder by sensors and detects the rotational speed of the engine at least three times during each combustion stroke by a rotation speed calculation device. The detected rotational speeds are evaluated by an arithmetic calculation device to identify the variation in rotational speed of each piston during a combustion stroke whereby the quality of combustion is, thus, determined. In a feature of the invention fluctuations in rotational speed caused by reciprocating inertia (.omega..sub.c) are calculated and eliminated from fluctuation in engine speed caused by combustion (.omega..sub.g) so that the quality of combustion based only upon variation in detected speeds caused by combustion is derived.
摘要:
There is disclosed an electrically-operated actuator in which a throttle valve is driven by a combination of the rotation of a motor and the operation of an accelerator by the operator, and besides the rotational force of the motor is not so transmitted to an accelerator pedal. This actuator is further provided with a fail-safe function. A parallelogrammic link is constituted by a link member fixedly mounted on a throttle shaft, a link member rotatably mounted on the throttle shaft and operatively connected to the accelerator pedal via a wire, a link fixedly mounted on a shaft rotatably mounted on the link member, and a link member connected to the link members by pins. The throttle shaft is coaxial with a shaft of the motor. A gear in mesh with a gear fixedly mounted on the motor shaft is fixedly mounted on the shaft, thereby forming a differential gear mechanism. Forces of springs act respectively on the throttle shaft and the link member in a direction to close the throttle valve. In order to prevent excessive opening and closing of the throttle due to the run-away of the motor, stoppers limit the angle of rotation of the motor.
