Abstract: An image processing apparatus for simulating a print output of a printing machine. The image processing apparatus firstly acquires color value information for converting color value information of image data so that a color reproduced on one surface of a recording medium by the printing machine based on the color value information is reproduced as an output. The image processing apparatus secondly acquires show-through color profile information for converting the color value information so that the color reproduced on the one surface by the printing machine as seen from the other surface is reproduced. The image processing apparatus then generates image data formed by composing first image data obtained by converting the color value information based on the color profile information, with second image data obtained by converting the color value information based on the show-through color profile information and by inverting the converted color value information horizontally or vertically.

Abstract: A drive circuit supplies a FB feedback signal having a predetermined frequency to drive electrodes to vibrate a vibrator. An angular velocity detecting circuit detects a vibratory movement caused in a direction normal to an oscillating direction of the vibrator based on a sensing signal of angular velocity sensing electrodes, thereby generating an angular velocity signal. A signal input circuit supplies a diagnostic signal having a frequency different from that of the FB signal, which is entered into the vibrator via diagnosing electrodes. A diagnosis circuit generates a breakdown signal based on a signal responsive to the diagnostic signal which is obtained from at least one of the drive electrodes and the angular velocity sensing electrodes.

Abstract: A personal computer incorporated in a numerical control device (CNC) has a function for emulating a CNC display circuit. This personal computer emulates a CNC display circuit and converts a transmitted display command A into a video signal for transmission to display means. The numerical control device (CNC) incorporating this personal computer need not to provide a display circuit for each of the CNC body and the personal computer, and, moreover, a switching circuit for selectively receiving the video signals from two display circuits and transmitting selected signal to the display means is not required either. Furthermore, the personal computer has a function for emulating a data input/output circuit of CNC. The personal computer inputs or outputs data transmitted from the CNC or data to be transmitted to the CNC, from or to a data input/output circuit in the personal computer to or from an external input/output device, through an input/output data RAM.

Abstract: An ink jet printer head includes a spacer including pressure generating chambers continuous to nozzle openings, ink supply paths, and reservoirs, a cover member for covering the pressure generating chambers in a sealing fashion, and pressure generating means for generating pressure in the pressure generating chambers in accordance with print data. In processing a silicon single-crystal substrate vertically oriented in (110) by anisotropic etching process, one of the walls of a path hole for forming a pressure generating chamber is aligned with one of the walls of a path hole for forming a reservoir. Walls defining the path hole for forming a pressure generating chamber, which are located in the vicinity of a nozzle opening, are connected to each other at an obtuse angle. As a result, the ink supply path serving as a narrow path for ink flow and the pressure generating chamber are formed as smooth flow paths.

A pair of driving electrodes are attached to the arms in order to generate vibrations in the arms. A pair of detecting electrodes, which are attached to the arms, detect the vibrations of the arms. Therefore, the pair of driving electrodes can cause the arms to vibrate uniformly and stably, so that a S/N ratio of the angular velocity sensor can be improved.
