摘要:
A photoelectric sensor includes a phototransmitter that outputs light toward a detection target region of an object; an optical receiver that receives the light outputted from the phototransmitter; a signal processing unit that outputs a signal indicating that the object is detected in response to a decrease of an amount of light received by the optical receiver; and two optical filters that are provided between the phototransmitter and the optical receiver to transmit only pieces of light having specific characteristics. In the phototransmitter, two kinds of light having different characteristics and that do not interfere with each other are outputted from output regions in the light transmitting surface; one of the two optical filters has a characteristic of transmitting only one of the two kinds of light and the other of the optical filters has a characteristic of transmitting only the other of the two kinds of light; the optical filters are disposed opposite to output regions of the pieces of light different from the pieces of light of a selecting target while located across a detection target region; and output directions of the two kinds of light are fixed such that whole surfaces of the optical filters corresponding to the characteristics are irradiated with the two kinds of light from the phototransmitter when the optical filters are disposed in a light transmitting surface while located away from each other by a predetermined distance or more.

摘要:
The method and apparatus for positioning a semiconductor wafer incorporates an X.Y axis drive mechanism for moving a mounting bed with a rotary part mounted on the mounting bed for supporting a wafer horizontally and rotating around the vertical axis. An edge portion distance measuring device optically measures a distance from the center position of the rotary part to the edge portion of the wafer along intervals of a definite angle. A distance and angle calculating device calculates a distance between the center position of the wafer and the rotational center of the rotary part relative to a reference line, and an angle of a line connecting the center position of the wafer and the rotational center of the rotary part with respect to the reference line. A notched portion calculating device calculates a deflection angle of the notched portion of the wafer with respect to the reference line, and a deflection amount calculating device calculates the X.Y deflection amount of the center position produced by moving the center position of the wafer based on the data of the angle and distance calculated by the distance and angle calculating device.
摘要:
When a composite material comprising a nylon non-woven fabric as a substrate and a paper material for cleaning a magnetic tape which has been stuck onto one surface or both surfaces of said nylon non-woven fabric is used as a ribbon used in a tape cleaning device for cleaning a magnetic tape and/or for cleaning a magnetic converter or a magnetic head for sending a magnetic tape, a decrease in a reproduction output due to static charge can be prevented, the generation of dust and the damage of the tape can be decreased, and a cleaning effect for the magnetic tape and/or the magnetic head can be improved.

摘要:
A light transmission module includes an optical converter for converting an electrical signal to an optical signal; a light transmission path for transmitting the optical signal converted by the optical converter; an electrical transmission path for transmitting an input electrical signal; and a control instructing unit for instructing stop of drive to the optical converter based on a detection of an input electrical signal. When an input electrical signal having a predetermined frequency is detected, the input electrical signal having the predetermined frequency is converted to an optical signal and transmitted in the light transmission path. When input of an electrical signal other than the predetermined frequency is detected, the electrical signal other than the predetermined frequency is transmitted by the electrical transmission path without being converted to an optical signal due to the stop of the drive of the optical converter.

A product design CAD data reconstruction unit 50 reconstructs product design CAD data used for product evaluation regarding an initial design so as to fulfill restrictive conditions obtained from the product evaluation based on a product structure for the initial design. The reconstructed product design CAD data is stored in a product design CAD data database 90. Upon reception of a corrected design obtained by correcting the initial design, the product design CAD data for the initial design is read from the product design CAAD data database 90, and the product design CAD data is corrected along a design surface of the corrected design.
