Title: Bearing monitoring device
Inventor: KONISHI YOSHIAKI
IPC: G01B7/14
Filed: 1990-02-20
Abstract: PURPOSE:To detect the degree of abrasion in the thrust and radial directions of a bearing continuousley and independently by installing a means for generating the different signals according to the position in the axial direction of a rotary shaft and detecting the distance from the means according to the signal. CONSTITUTION:A signal generating means consisting of a rectilinear projecting stripe 34 parallel to the axis of a rotary shaft 30 and a curved spiral projecting stripe 16 is installed on the surface of an end nut 32 installed at the terminal of the rotary shaft 30. A distance sensor 38 consisting of a noncontact type displacement meter, etc., is installed oppositely to the signal generating means, and the detection signal is supplied to signal processing device. When the end nut revolves, pulse is generated at the position where both the projecting stripes 34 and 36 and the distance sensor 38 are brought to the closest position. When the bearing is worn out in the radial direction, the above-described closest distance reduces according to the degree of abrasion, and pulses increase. When abrasion is developed in the thrust direction, the pulse interval due to the projecting stripes 34 and 36 varies. Accordingly, the abrasion in both the directions can be detected continuously and independently.

Title: Actuator driving circuit
Inventor: MATSUI SHOICHI
IPC: G11B21/10
Filed: 1988-02-19
Abstract: PURPOSE:To perform tracking at the center of a track so as to prevent decline of C/N by correcting the offset produced in the quantity of the light which is split by the optical beam at the center of the track and projected on a photodetector element. CONSTITUTION:Since tracking error signals cut grooves at the time of track jumping, the maximum and minimum (negative maximum) values are produced. The maximum and minimum values are respectively held by a peak holding circuit 4 and inversional amplifier circuit 6 until the next track jump controlling signal comes. Then the values are inputted to a differential amplifier circuit 7 and a mean value is obtained. The differential between the mean value and the tracking error signals is taken at a differential amplifier circuit 8 and a servo is actuated so as to make the output of the amplifier circuit 8 zero. Therefore, even when a tracking actuator operates within the range of <=+ or -0.1mm from the center of a movable section, tracking can be performed at the center of a track and decline of C/N is reduced.

Filed: 1986-02-25
Abstract: PURPOSE:To improve the sharpness and resolution of an image by using a copolymer of a polycrotonic ter-butyl ester or crotonic ter-butyl ester as a high-polymer resist material. CONSTITUTION:The film of the copolymer of the polycrotonic ter-butyl ester or crotonic ter-butyl ester is formed by dissolving said copolymer into an org. solvent, refining the soln., supplying the soln. onto a wafer consisting of silicon, etc. and forming the thin film of the soln. on the wafer. The thin film is subjected together with the wafer to a prebaking treatment for a specified period at a specified temp. The adhesiveness of the thin high-polymer film which is a base material to the wafer is improved by such heat treatment and at the same time the desorption of the ternary butyl group from the structural unit of part of the crotonic ter-butyl ester constituting the thin film arises and consequently a crosslinking reaction is induced, by which the thin film effectively controlled in the solubility with the org. solvent to be used for a developing soln. is obtd. The sharpness and resolution of the image are thereby improved.
