  • Patent number: 8022376
    Abstract: A method for manufacturing a semiconductor device or a photomask by exposing a pattern while scanning a plurality of deflection regions determined depending on a deflection width of an exposure device on an exposure target with electron beams, enables a computer to execute a step of extracting a first pattern that exists near the boundary of the deflection region and in a first deflection region, a step of searching a second pattern that is adjacent to the first pattern and in a second deflection region different from the first deflection region, and a step of performing data processing of exposure data in accordance with a width of the first pattern so as to minimize the change in distance between the extracted first pattern and the searched second pattern due to positional deviation of the deflection region.

  • Patent number: 7913258
    Abstract: A remote machine uses a process control unit to monitor a process for a Web browser program. When the process for the Web browser program starts to operate, an operating time therefor starts to be measured. When the operating time reaches a predetermined time, the process for the Web browser program is forcefully terminated. After that, unless the remote machine 2 is rebooted, that is, unless a RAM is cleared, the process for the Web browser program is forcefully terminated immediately after its start.

  • Publication number: 20110018399
    Abstract: A piezoelectric device has a piezoelectric vibration element mounted in a package wherein the piezoelectric vibration element comprises two stick-like vibration legs; a central leg provided between the two vibration legs; a coupling portion that couples one end of each of the two vibration legs and one end of the central leg; and a protrusion portion that is coupled to another end of the central leg, has a predetermined angle, neither 0 nor 180 degrees, to the length direction of the central leg, and extends into a direction not interfering with the driving legs. In making the piezoelectric device smaller and thinner, this configuration avoids interference between a support point on the central leg, provided for supporting the vibration element, and conductive electrodes, improves insulation between the conductive electrodes, and reduces the generation of short-circuits between the conductive electrodes.

  • Patent number: 7765375
    Abstract: In a computer including a processor for executing a program and a storage that includes a first storage area and a second storage area for storing objects generated by the executed program, the processor stores objects generated by executing the program in the first storage area. If an object stored in the first storage area is accessed, the processor records access information of the accessed object. The processor extracts a leak object having a high possibility of memory leak on the basis of the recorded access information, and moves the extracted leak object to the second storage area.

  • Publication number: 20090128632
    Abstract: A video signal produced through a shooting operation of a camera is sent to a motion detecting unit which detects a motion included in the video signal to set an area of the motion as a space motion area and inputs information of the area to a distance determination circuit which calculates distance between the motion area and the camera by use of a parallax signal produced from stereo cameras disposed in the camera to send information of the space motion area and the distance to a mask determination circuit. The mask determination circuit conducts a comparison between the space motion area information and the space mask area information and between the distance information of the motion area and that of the space mask area, and resultantly compares three-dimensional positions between the detected motion and the mask to determine a position relationship therebetween.
