摘要： A control means individually turns each switching means on or off so that a current has a waveform which is approximate to a parabolic waveform and is appropriate for focusing current flows in a focusing coil, synchronizing with a horizontal sweep. When the focusing current increases, energy is transferred from the power source to the focusing coil. When the focusing current decreases, energy is returned from the focusing coil to the power source by a flywheel current. Thus, the focusing current is supplied with less consumption.
摘要翻译：控制装置单独地打开或关闭每个开关装置，使得电流具有近似于抛物线波形的波形，并且适合于聚焦线圈中的电流流动，与水平扫描同步。当聚焦电流增加时，能量从电源传递到聚焦线圈。当聚焦电流降低时，能量通过飞轮电流从聚焦线圈返回到电源。因此，聚焦电流被提供更少的消耗。

摘要： A projector 100 projects an image onto a screen 200 by having light from a light source 111 pass through light valves 108˜110 corresponding to RGB colors and a projection lens 101. A special pattern is displayed on the light valves 108˜110 so that an image of the special pattern is projected onto the screen 200. The projector includes a half mirror 112 that directs light, which has been reflected back off this image on the screen 200 and back through the light valves 108˜110, toward the collective lens 113, and a light detecting element 114 for detecting the intensity of the light collected by the collective lens 113. Based on the detected intensity, the microcomputer 116 automatically adjusts the projection parameters of the projector 100.

摘要： An APL detection unit detects the APL for each unit field time period of an input video signal, and a light source control data production unit produces, depending on the results of the APL detection, a light source control signal at a minimum level which can stably drive a light source when the APL is 0% up to a predetermined value A1, a light source control signal at a maximum level which can stably drive the light source when the APL is a predetermined value A2 up to 100%, and a light source control signal which dynamically varies depending on the APL when the APL is between the predetermined value A1 and the predetermined value A2, to drive the light source on the basis of the light source control signal. As a result, it is possible to mitigate the lack of a contrast feeling and the occurrence of a floating blackness, as well as to improve the reliability of the light source.

摘要： A projector that can be easily set up and adjusted is disclosed. In accordance with a projection condition inputted into a microcomputer via a remote-controller, the microcomputer selects an optimum projection lens by referring to correlation data showing a relation among a projection lens, a projection display size, and an optimum projection distance. The microcomputer has a screen to indicate an optimum projection lens and projection distance that satisfy the inputted projection condition. The microcomputer calculates the amounts of zoom and focus adjustments to be made to the projection lens with reference to the correlation data so as to attain the projection display size and the microcomputer automatically drives the projection lens via a zoom driving unit and a focus driving unit.

摘要： An apparatus for receiving and selecting high-definition television signals and NTSC standard television signals includes a high-definition display screen device having an aspect ratio of 16 to 9. The NTSC standard television signals have an aspect ratio which is different than the 16 to 9 aspect ratio of the high-definition display screen device. A first signal converter is for converting the NTSC standard television signals into first quasi-high-definition television signals identifying a first displayed image corresponding in vertical length to a vertical length of the high-definition display screen device. A second signal converter is for converting the NTSC standard television signals into second quasi-high-definition television signals identifying a second displayed image corresponding in horizontal length to a horizontal length of the high-definition display screen device. Switching circuits are provided for selecting one of the high-definition television signals and the first and second quasi-high-definition television signals.

摘要： The natural rubber of the present invention is natural rubber obtained by leaving standing for a prescribed period of time a hydrous coagulum obtained from a natural rubber latex to which a preservative is added and/or from a coagulum of a natural rubber latex to which a preservative is added and drying it. The natural rubber coagulum is inhibited from being changed in a molecular weight even in a standing step (aging) in a high moisture condition, whereby the natural rubber having stable mechanical properties is obtained. An isothiazoline base compound is used for the preservative. Further, a rubber composition containing the natural rubber is prepared, and a tire is produced by using the rubber composition.

摘要： A focus adjustment changeover circuit for a projection display television receiver having red, green and blue-emission CRTs includes a changeover switch for selecting an operating mode in which a level of current is supplied to the static focus coil of the blue-emission CRT such as to precisely focus the electron beam of that CRT, so that projection lens focus adjustment for that CRT can be easily performed with a test pattern signal being projected, and an operating mode in which the current supplied to that static focus coil causes the electron beam of the blue CRT to be slightly defocused, so that white balance adjustment of the television receiver can be executed while a television picture is projected.
