Title: Feed controller of optical pickup
Inventor: ITO SHIGEHIRO
IPC: G11B7/085
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To eliminate reciprocal action around an optical axis center even when the friction on an optical pickup and a feed mechanism is decreased and to prevent the life of a motor from being deteriorated and a tracking servo from being deviated. SOLUTION: An insensitive zone is set in a servo digital signal processor 6 for supplying a servo command to a feed motor 13 in accordance with the deviation of an optical axis so that the servo command is made not to be supplied when the amount of deviation of the optical axis is within the range of a described amount. Moreover, since the width of the insensitive zone in the outer peripheral direction of an optical disk 15 is not made to be the same as that of the inner peripheral direction, and an objective lens shifts to the outer peripheral direction according to a track, the width in the outer peripheral direction is made to be about a half of the deviation amount of the optical axis allowed by the optical characteristic and the width in the inner peripheral direction is made to be the allowable deviation amount of the optical axis. Consequently, the optical pickup 1 is not fed until the deviation of the optical axis exceeding the range of the described amount is generated even when the frictional load is lowered, the reciprocal operation about the optical axis center is prevented and the variation of the feed amount is absorbed since the stipulated amount in the inner peripheral direction is widened.

Title: Method and device for editing and copying
Inventor: KATO ICHIRO
IPC: G03G15/043
Filed: 1985-08-22
Abstract: PURPOSE:To specify the position of editing and copying accurately by specifying the desired area of an original according to coordinates of measures imprinted in the 1st copying operation and obtaining a copy wherein the image except in the desired area is erased in the 2nd copying operation according to the area specification. CONSTITUTION:A motor 35 is driven in editing mode so as to take up a flexible sheet body 34 during the 1st copying operation in synchronism with the rotation of a photosensitive drum 14. The sheet body 34 moves from a transparent part 34a to a measure type light shield part 34b and the composite copy of the copy image of an original and measures of the measure type light shield part 34b is taken. Then, a copy is taken in the 2nd copying operation so that the transparent part 34a faces the optical path of exposure and the exposure image of the original is formed on the drum. A position specifying means 41 reads an area to be cut from the composite image of the copy image of the original formed in the 1st copying operation and the measures of the light shield part 34b to obtain X and Y coordinates. Consequently, the electrostatic latent image of a no-image formation area is erased by an image erasing means 19 to obtain the image of only the desired part.

Title: Apparatus of measuring dropping heavy object
Inventor: MORIYAMA MASAO
IPC: G01G13/00
Filed: 1990-07-11
Abstract: PURPOSE:To measure the weight of a heavy substance within a container at the receiving position with high accuracy regardless of the supplying shock every time the substance is supplied by supporting the container by a bearing through an inverse U-shaped load transmission platform and a rotary driving mechanism. CONSTITUTION:In the standby state, a container 27 for receiving an object is put on a load transmission platform 19. A leg part 28 protruding downward of the container 27 is spaced from a sensitive part of a weighing scale 24. When a heavy object is supplied into the container, the load acts upon a bed 1 through the load transmission platform 19 and a rotary driving mechanism astride the container and bearing 6-9 at both sides of the container, and therefore, it becomes possible to receive the large load without concentrating the load locally. When the heavy object is supplied, a vertical driving mechanism 30 is activated to move a vertical shifting part upwards, and the weighing scale 34 is raised. Therefore, the sensitive part butts against the leg part 28 of the container 27 which is in turn lifted while extending a link 44. The container 27 containing the heavy object is separated from on the transmission platform 19 at the uppermost position. The gravity of the container 27 acts totally to the sensitive part of the weighing scale 34, and the weight of the heavy object is measured.

Title: Recording head for electrostatic recording device
Inventor: YUASA KAZUHIRO
IPC: B41J2/39
Filed: 1983-10-03
Abstract: PURPOSE:To arrange so that generation of a large blot of dots may effectively be prevented in a recorded image, by keeping a distance between a stylus electrode and its adjacent one of more than 60mum in a recording head. CONSTITUTION:A swing voltage of different polarity from each other distributed centering around an applied recording bias voltage VB is applied to a stylus electrode 2 and its corresponding auxiliary electrode 3 respectively in a recording head 1. In this way, an electrostatic latent image is formed in the surface of a recording medium 4. When stylus electrodes 21 and 22 adjacent to each other are in ''ON'' position and ''OFF'' position respectively, an electric field under the electrode 21 spreads extensively resulting in the easy generation of a huge dot on account of a surfacial electric potential VS of the evenly charged recording medium 4, electric potential VO of an electroconductive layer 42 by the voltage VB and an electric potential V1 by a swing voltage Vseg. Therefore, if the stylus electrode 2 is arranged in a zigzag form and a distance between the electrode and its adjacent one is kept more than 60mum, the generation of a large blot of dots is prevented.
