  • Publication number: 20040026758
    Abstract: Disclosed herein is an image sensor. The image sensor has a CdTe plate, a plurality of hole-type electrodes, and a voltage-applying unit. The hole-type electrodes are arranged at predetermined intervals in the direction of thickness. The voltage-applying unit applies a voltage to the hole-type electrodes. One of the electrodes is not adjacent to any other electrode and is used as an anode. The remaining electrodes are used as cathodes. A sensor-element array is provided on the detecting surface of the image sensor. The array comprises a plurality of sensor elements arranged in the form of a matrix. Each sensor element comprises an anode, a plurality of cathodes, and CdTe lying between the anode and the cathodes.

  • Publication number: 20030137654
    Abstract: Before measuring a wavefront aberration of a projection optical system, an image formation position of an image of a pattern of a test reticle which is formed on a predetermined surface is detected by an AF sensor. Based on a result of this detection, the position of an incident surface of a wavefront aberration measurement unit is adjusted, and a position of an image of the pattern with respect to the incident surface is adjusted. After this adjustment, the image of the pattern formed through the projection optical system is detected by the wavefront aberration measurement unit, and a wavefront aberration detection section is used to obtain wavefront aberration information of the projection optical system based on a result of this detection.

  • Publication number: 20030000439
    Abstract: A stitch balancing thread tension 11 of a sewing machine 1 includes a rotary disk 17 having a surface extending perpendicular to an axial direction of a shaft 16 on which the rotary disk 17 is mounted. The thread breakage detection device includes a permanent magnet member 21 attached to the surface of the rotary disk 17, a hole element 22 that detects a magnetic field generated at the permanent magnet member 21 and outputs detection signals, and a detection unit that detects the thread breakage based on the detection signals from the hole element 22. Because the thread breakage detection device is integrally formed to the stitch balancing thread tension 11, the thread breakage detection device can be provided to the sewing machine 1 without increasing a number of components and the size of the sewing machine 1.

  • Patent number: 5899157
    Abstract: In a presser foot device of a sewing machine, a presser foot is vertically movably supported to a sewing machine body frame by a presser bar. A drive device moves the presser bar up and down in accordance with a drive signal. A sensor detects when the presser foot is raised close to a top dead center position, that is, a predetermined position. Based on the detection by the sensor, a control device controls the drive signal for the presser foot drive device.
