  • Publication number: 20060028153
    Abstract: Disclosed herein is a discharge lamp lighting device which realizes the minute control of the lighting sequence and electric power of a high-pressure discharge lamp and the control of various anti-error protecting functions by mounting a microcomputer. However, since microcomputer processing typically progresses in accordance with the programs previously recorded on a ROM, various actions of the discharge lamp are controlled in accordance with ROM-recorded data settings. To modify these settings, the contents of the ROM need to be updated. Therefore, a function for communicating with an external device is assigned to the microcomputer so that various data settings can be modified.

  • Patent number: 6861837
    Abstract: A rotation angle detector is simple in structure and is capable of angle detection with a high resolution. First and second detecting units detect rotations of first and second detecting members rotating in association with a rotating member as detection signals in which predetermined waveforms continue. A control unit connected with the first and second detecting units detects a difference between the waveforms output from first and second detecting units as a gradually increasing detection signal and detects a rotation angle of the rotating member from two signals: the gradually increasing detection signal and the waveform output from the first detecting unit.

  • Patent number: 6753255
    Abstract: A chemical vapor deposition process controls the thickness of a film on an edge of a wafer by modifying the density of flow gases at the edge of the wafer through the use of a gas flow control ring. The deposition process is performed with the gas flow control ring disposed about a wafer holding region on a wafer holder. The top surface of the gas flow control ring is controlled relative to the top surface of the wafer to adjust the thickness of the film deposited on the wafer edge. In one particular embodiment, the gas flow control ring has a top surface in the same plane as the top surface of the wafer. In another embodiment, the deposition process is performed with the clearance between the inner diameter of the gas flow control ring and the periphery of the wafer minimized.

  • Patent number: 6270270
    Abstract: A printing apparatus has a small size that facilitates replacement of rolled paper, removal of jammed paper, etc., and alleviates the likelihood of a paper jam with a considerably simple structure. The printing apparatus comprises a rolled-paper holder (2), which is provided with a first holder (2b) for use in carrying out printing on rolled paper (1), and a second holder (2a) for use in setting the rolled paper (1). The rolled paper (1) is moved from the second holder (2a) to the first holder (2b) as a main body of the apparatus is shifted from a paper setting position to a printing work position, thereby facilitating the setting of the rolled paper (1) and removal of jammed paper, since the rolled paper (1) can be temporarily supported by the second holder (2a) in order to provide sufficient work space when replacing the rolled paper (1) or removing jammed paper.
