摘要:
An image processing device comprises an encoder for encoding inputted image data in the form of fixed length compression. The encoded data encoded in the form of the fixed length compression by the encoder is stored in a hard disk through an encoded data buffer which is a toggle buffer. Accordingly, the image data can be stored in the hard disk at a constant speed, and a capacity of the encoded data buffer can be minimized since the data amount after data compression is decided. As a result, it is not necessary to provide a semiconductor memory corresponding to storage of one screen, so that a low cost image processing device is obtained.

In an image processor using image data compression coding of a fixed compression rate, the data of one color of image data is stored in a coding memory without coding, if compression coding is not necessary. If the compression coding is necessary, the data is coded by an encoder by compression coding with a compression rate of 4, and the coded data of four colors, i.e. cyan, magenta, yellow and black, are stored in the coding memory. Since the image data is compressed by a fixed compression rate, it is possible to estimate the quantity of data after compression. As a result, the coding memory can be used effectively, without using a fixed disc unit.

A method of simulating a color image. Firstly, images are displayed and printed, respectively, by means of display device and hard copy unit on the basis of the same image data. Secondly, the image data are subjected to a color conversion process by the use of color conversion parameters having different values from one another, and a plurality of processed images are displayed by the display device. Moreover, from among the processed images being currently displayed there is selected a processed image having substantially the same colors as the image recorded by the hard copy unit, to thereby set the value of the color conversion parameter. Subsequently, a color conversion parameter representing an inverse conversion to the color conversion by way of color conversion parameter which has been set is set into the hard copy unit to thereby print the image based on said image data.

An arm rest mounted to an arm rest support portion of a trim assembly, includes a substrate and a pad on the substrate. The substrate has an energy absorbing structure adapted to be collapsible in a predetermined direction in response to application of a load to the arm rest in the predetermined direction. The energy absorbing structure of a generally honeycomb shape includes a plurality of ribs interconnected to define a plurality of openings. Resilient pawls and a resilient clip are disposed on the substrate to be engaged with peripheral edges of insertion holes of the arm rest support portion.

A photosensitive plate includes a transparent electrode layer, a transparent carrier blocking layer of polyvinyl carbazole and a P type photoconductive layer superposed on one another and opposed to a dielectric recording medium with a gap therebetween. While a recording voltage is applied across the electrode layer and recording medium with positive polarity being imparted to the electrode layer, an imaging light irradiates the photoconductive layer to transfer a corresponding electrostatic latent image formed on that layer to the recording medium across the gap. For an N type photoconductive layer, a negative polarity is imparted to the electrode layer.

An interior member on a side wall of a passenger room is formed with an arm rest body projecting inwardly of the passenger room and has a placed member on an upside part of the arm rest body for providing a place for an arm of the passenger to be put thereon, the placed member being detachably attached to the arm rest body and lockingly engaged therewith by an engagement mechanism having lock pawls integral with the placed member and engaged with an edge of an opening formed in the upside part of the arm rest device and ribs integral with the placed member and brought into abutment with the edge of the opening so that, as a primary collision has happened at a lateral side of vehicle, a secondary collision load of the passenger imposed on the arm rest body forces the placed member to be released from the locking engagement by the engagement mechanism.

An optical wavelength stabilizing system including a laser diode for emitting signal light, a Peltier element for controlling a temperature of the laser diode, and a drive circuit for driving the Peltier element. The signal light is branched into two components by an optical coupler. In an optical path of one of the two components obtained by the optical coupler, there is inserted an optical filter having a portion whose transmittance continuously changes according to wavelength. The signal light component passed through the portion of the optical filter is detected by a photodetector. An output current from the photodetector is converted into a voltage, which is then input into a comparator. The comparator compares the voltage output from the photodetector and a reference voltage to input a voltage difference therebetween into the drive circuit.

A method for cutting a sapphire substrate whose A plane functions as a main surface is carried out after forming a semiconductor device or in order to form a device. Here a just A plane of the sapphire substrate is represented by a (11-20) plane, a line of intersection of the main surface and at least one of a (10-12) plane and a (0-112) plane is defined as a base line and a direction which an angle decreases as it reaches the axis c is defined as a positive direction. In that case, a separation line is formed along a first direction which makes an angle of 0 to 4 degrees with the line of intersection and a second direction which is perpendicular to the first direction.
