摘要:
A projection-type liquid crystal display device having a light source for emitting a luminous flux; a liquid crystal light valve for modulating the luminous flux emitted by the light source means; a liquid crystal drive circuit for applying the common voltage to the common electrode and the video signal to the source electrode; a projection lens for projecting the luminous flux modulated by the liquid crystal light valve onto a screen; a liquid crystal temperature detector for detecting temperature in the vicinity of the liquid crystal light valve; and a controller. The controller controls the common voltage and/or the source voltage on the basis of values detected by the liquid crystal temperature detector in such a way that fluctuation in the light transmittance of the liquid crystal light valve means is reduced.

A method and apparatus for adjusting a color difference signal of an image includes a video signal processor. The video signal processor receives a luminance signal and color difference signals representing the image, and accesses a color saturation level from a color saturation level table stored in memory based on the color difference signals. The video signal processor then detects flesh tone in areas of the image based on the luminance signal and the color saturation level, and generates a flesh tone detecting signal based on results of the flesh tone detection.

A biaxially oriented blow-molded bottle-shaped container made of synthetic resin comprises a rectangular tubular body provided with a generally central circumferential groove having upper and lower sidewalls. The sidewalls are inclined at an oblique angle within a range of 21.degree.-28.degree. with respect to a vertical longitudinal axis of the container. The rectangular tubular body includes flat walls, each having a central recessed portion with a bottom wall comprising a shaped panel wall for compensating for deformation due to reduced pressure in the container and a shaped peripheral groove invertedly curved around the shaped panel wall. The shaped panel wall has ribs traversing the shaped panel wall parallel to each other, and a crest of each of the ribs has a larger radius of curvature than that of a root thereof. The rectangular tubular body has an upper end which is a regular polygon having twice as many corners as corner panels of a main portion of the body and a shoulder having a lower end portion connected to the upper end of the body. The lower end portion of the shoulder is in the form of a regular polygonal truncated pyramid shape.
摘要:
A blow-molded bottle-shaped container of biaxially oriented synthetic resin integrally molded with a neck at the top of a cylindrical body thereof, comprising a pair of recesses depressed inwardly on the cylindrical wall thereof at both sides of the cylindrical body and spaced so that one remaining container body surface of the container body forms a grip by the formation of said recesses. The blow-molded bottle-shaped container of biaxially oriented synthetic resin can enhance sufficiently the mechanical strength of the recesses formed on the container body by providing reinforcing ribs for effectively dispersing internal pressure acting one the recesses.

The present invention relates to a saturated polyester resin bottle made thin by biaxial orientation and comprising a trunk portion formed to have a regular polygonal cross section consisting of a plurality of generally upright flat sides separated by vertically oriented ribs. When the interior of the bottle is subjected to a vacuum, the flat sides uniformly warp radially inwardly to accommodate the vacuum without detracting from the appearance of the bottle.

In a serial signal transmission system for transmitting data signals in a serial manner from a transmitting part to a receiving part of the system, both supplied power from a common power source, are provided a signal line extended between the two parts, a device for detecting the polarity of the power source voltage, a device for generating binary pulses in response to the output of the polarity detecting device, and a control element provided in the signal line. The control element is made conductive in accordance with the binary pulses constituting the data signals.

This invention relates to process for preparing saturated polyester resin bottles, that the residual strain of the bottles is reduced and the deforming temperature is elevated. The process is that a heated intermediate material (1) made of a saturated polyester resin is set in a mold (5), then compressed air is blown in the intermediate material (1) to orient the same biaxially, temperature in thus shaped bottle is elevated to a temperature higher than the heating temperature of the intermediate material (1) under the elevated pressure to effect thermal fixing and thereafter the saturated polyester resin bottle (19) is taken out.
摘要:
A synthetic resin bottle produced by blow-molding a parison of a synthetic resin. In the blow-molding process of the parison, the portion of the parison supporting the handle is prevented from being expanded, thereby to sufficiently increase the supporting strength of the handle. Since the bottle product has its drum recessed in the vicinity of the handle, the grip of the handle can be facilitated.

A first intermediate image generating means (1) generates an intermediate image (D1) by extracting a component of an input image DIN in a particular frequency band; a second intermediate image generating means (2) generates an intermediate image D2 having a frequency component higher than the intermediate image (D1); a first intermediate image processing means (3M) generates an intermediate image (D3M) by amplifying the pixel values in the intermediate image (D1); a second intermediate image processing means (3H) generates an intermediate image (D3H) by amplifying the pixel values in the intermediate image (D2); and an adding means (4) adds the input image (DIN) and the intermediate image (D3M) and the intermediate image (D3H) together to obtain an output image (DOUT). A first amplification factor (D3MA) and a second amplification factor (D3HA) are determined according to pixel values in the input image (DIN). Even if the input image includes a fold-over component on the high-frequency side or does not include an adequate high-frequency component, an enhanced image can be provided without causing overshoot.

An image display device and an image display method are provided so as to suppress consumption power and provide a more brightly colored display image. The image display device is provided with a light modulating means wherein image data is inputted and an image is formed by modulating light from a light source based on the image data. The image display device is also provided with a color information detecting means for detecting a quantity of a chromatic color component of an image expressed by the image data; a light source control data generating means for generating light source control data for controlling brightness of the light source; and a light source control means for controlling the brightness of the light source based on the light source control data.
