Inventor: MOTOMURA YOSHIHIRO
IPC: G11B5/39
Filed: 1991-03-04
Abstract: PURPOSE:To provide a magnetoresistance effect element having no Barkhausen noise and high performance in simple steps. CONSTITUTION:A ferromagnetic magnetoresistance effect layer 2 is formed on a nonmagnetic-base 1, ions are partly implanted (3) to the layer 2, and then heat treated in a magnetic field.

Title: Arithmetic state display system for ddc
Inventor: SAKAGUCHI KAZUO
IPC: G05B23/02
Filed: 1990-02-20
Abstract: PURPOSE:To efficiently execute the check and control of control logic by displaying the trend graph of a control block near the control block of an arithmetic state display screen. CONSTITUTION:An arithmetic result output value 12 of a control block 11 is periodically updated and a simplified trend graph 13 is also periodically updated together. The simplified trend graph 13 links output values for 5 updating periods adding a current time point to the preceding 4 updating periods by broken lines in order from the left side in a frame equipped with the same size as the control block 11. Namely, a longitudinal axis scale defines the maximum and minimum values of the output values in the 5 periods of respective elements as upper and lower limits, and when the output value difference is less than 10, the difference between the upper and lower limit is defined as 10 so as to exactly grasp increase/decrease tendency. Thus, the increasing/ decreasing state of the arithmetic result in each control block until a screen display time point can be known.

Filed: 1988-02-19
Abstract: PURPOSE:To eliminate the number of matchings, to reduce the number of times of matchings and to shorten a matching processing time by matching a picture pattern obtained with image pickup to a possible distortion pattern corresponding to a recognized objective character. CONSTITUTION:Based on a image pickup timing signal obtained from a photo- interrupter 2, the image is picked-up by a camera 1, the picture pattern is segmented, and whether or not the segmented width is large is judged. When it is judged to be large, the picture pattern is matched to normal matching patterns P1 and P2, and the recognizing signal is outputted to a recognition display device 4. When the segmented width is judged to be small, the picture pattern is matched to possible distortion matching patterns P3-P6. When it cannot be judged to be large or small, the picture pattern is matched to the all matching patterns P1-P6. By using the title device, since the picture pattern is unnecessary to be matched to the all matching patterns, a correcting processing for normalization can be omitted.

Filed: 1991-02-06
Abstract: PURPOSE:To speed up the movement of a mirror stand without altering the specifications of a motor by providing magnetic members for assisting the operation of the mirror stands at specified positions. CONSTITUTION:A permanent magnet 10 as a magnetic member is mounted on a first mirror stand 5, and a permanent magnet 11 as a magnetic member is mounted under a rail 9 as a sliding member.
