摘要： A digital subscriber line formed by terminal equipment, a network control device including a plurality of the terminal equipment, and an exchange terminal. In a waiting state of the digital subscriber line, the network control device is placed in a state which can only receive a signal. A sending portion of the network control device is driven when, at a call from the terminal equipment, the terminal control device receives a line activation signal from the exchange equipment and when, at an incoming state from the state from the exchange terminal, the terminal control device receives a line activation from the exchange equipment. The synchronization pattern signal is sent from the sending portion to the exchange terminal so that the synchronization of the exchange terminal is established.

摘要： A distributed amplifier with a simple structure that permits miniaturization of circuit in which the input-side transmission line of the distributed amplifier is constituted by a coplanar line having a signal line and a ground face formed on the upper face of a dielectric substrate and the output-side transmission line of the distributed amplifier is constituted by a microstrip line having a signal line formed on the upper face of the dielectric substrate and a ground face formed on the lower face of the dielectric substrate. In addition, a plurality of amplification transistors is formed on the upper face of the dielectric substrate and each of the electrodes is connected to the signal line or the ground face that is formed on the upper face of the dielectric substrate. Because a large transistor-drive current does not flow to the input-side transmission line, the signal line can be made narrow and there is no increase in the required surface area even in the case of a coplanar line. Further, because the ground face of the coplanar line can be formed on the upper face of the dielectric substrate, the source electrodes or similar of the transistors can be grounded easily with a simple structure.
摘要翻译：具有简单结构的分布式放大器，其允许分布式放大器的输入侧传输线由具有形成在电介质基板的上表面上的信号线和接地面的共面线构成的电路的小型化，并且输出分布式放大器的侧面传输线由形成在电介质基板的上表面上的信号线和形成在电介质基板的下表面上的接地面的微带线构成。此外，在电介质基板的上表面上形成多个放大晶体管，并且每个电极连接到形成在电介质基板的上表面上的信号线或接地面。由于大的晶体管驱动电流不流到输入侧传输线，所以即使在共面线的情况下，也可以使信号线变窄并且不需要增加所需的表面积。此外，由于可以在电介质基板的上表面上形成共面线的接地面，所以可以以简单的结构容易地接地晶体管的源极或类似物。

摘要： A projection-type display apparatus in accordance with the invention reduces the margin formed around the image forming range of the light valves, and forms a bright projected image. Emitted light from a light source lamp unit of a projection-type display apparatus illuminates liquid crystal light valves of each color via an integrator optical system. First and second lens plates of an integrator optical system that serves as a uniform illuminating optical system are disposed such that the attachment position thereof is capable of fine adjustment in a direction vertical to the optical axis. By performing fine adjustment of the attachment position of these, the forming position of the illumination range B can be adjusted to include the image forming range A of the liquid crystal light valves. Accordingly, there is no need to provide a wide margin around the image forming range A, taking shifting of the forming position of the illumination range B into consideration. Thus, efficient usage of the illumination light can be increased, thereby improving the brightness of the projected image.

摘要： The present invention provides a technique that reduces color non-uniformity in a color image projected and displayed by a projector. The projector that projects and displays the color image includes an illumination optical system, a color light separation optical system, first through third electro-optical devices, a color light synthesizing optical system, and a projection optical system. The projector generally has one or a plurality of light bundle adjustment optical systems provided in one or some of three optical paths, which respectively connect the color light separation optical system with the first through the third electro-optical devices. Each light bundle adjustment optical system regulates size of a light bundle of a selected color light. The technique of the present invention adjusts specific one or plural image signals according to pixel positions of a color image, so that cross sectional luminance distributions of first through the third modulated lights on a light-exiting side of the color light synthesizing optical system have substantially the same gradients at least when the image of interest to be projected and displayed is a white image. This arrangement effectively reduces color non-uniformity in the resulting color image, due to the presence of the light bundle adjustment optical system.

摘要： A liquid crystal device that modulates light in accordance with supplied image information comprises a plurality of pixels arranged in a matrix, each pixel having an opening to allow passage of light, and an array of micro-lenses arranged in a matrix that divides illumination light into a plurality of partial light beams and converges the light beams to a light incidence plane of the pixels. In the liquid crystal device, the characteristics of the micro-lenses are adjusted to increase a proportion of light exiting from the opening of each pixel substantially parallel to a clear viewing direction of the liquid crystal device compared to a proportion of light parallel to other directions. Each micro-lens is positioned so that a line connecting the optical center of the micro-lens to the center of the incident surface of the corresponding pixel is substantially parallel to the clear viewing direction.
