Title: Apparatus for positioning measuring point of electron beam prober
Inventor: KAWABATA MASAAKI
IPC: H01J37/28
Filed: 1984-11-20
Abstract: PURPOSE:To obtain an apparatus for positioning measuring point of electron beam prober which has flattened a structure for moving a sample in two dimensions by providing a planetary rotating stage which places a normally and reversibly rotating sample within the rotating stage which normally and reversibly rotates. CONSTITUTION:A sample 11 is placed at the position deviated from the center of stage 8 within a vacuum chamber 4. When a rotating stage 6 is rotated by gears 13, 15 through normal and reversible drive of motor 14, a planetary rotating stage 8 also rotates with a carrier 17 and a support axis 18. Thereby, the sample 11 moved in the circumferential direction. When the planetary rotating stage 8 rotates due to the normal and reversible drive of motor 20 at the rotating position of stage 6, the sample 11 further moves in the diameter direction. Thus, the sample 11 moves in two dimensions and can be located to any part of stage 6. As explained above, only two kinds of stages are arranged in such a way as forming the bottom surface at the bottom part of vacuum chamber. Therefore a thin chamber can be formed in small size and it can be vacuumed easily.

Title: Image formation device
Inventor: TAGAWA HAJIME
IPC: G03G15/041
Filed: 1990-09-18
Abstract: PURPOSE:To prevent an image which is not in one page of a continuous document from being transferred by irradiating an area other than the area of an image carrier where an electrostatic latent image of one page of the continuous document is formed by a light irradiation means and forming a no-image formation area. CONSTITUTION:A computer detects the size of Z paper 65 optionally by a photosensor 73 and detects the form size of a paper feed cassette by a detector. The microcomputer in a copying machine main body calculates an image area to be erased from the detected values. A photosensitive body, on the other hand, is charged electrostatically and then light is emitted according to the calculated value of the erasure area by an erasure array. Consequently, only a potential corresponding to a part A is left on the photosensitive body and the electrostatic latent image of only one page of the Z paper 65 is formed; and no unnecessary image is formed on the image carrier and the image of only one page of the continuous document can be formed.

Abstract: PROBLEM TO BE SOLVED: To reduce plating defect by readily removing remaining bubbles in a recessed surface and realizing uniform roughening by immersing a solid molded item in isopropyl alcohol and thereafter roughening it by immersing in an etchant with isopropyl alcohol retained by a recess. SOLUTION: A solid circuit board is manufactured by forming a conductor circuit 4 in a surface 3 with a recess 1 of a solid molded item 2 which has the recess 1 and consists of electrically insulating resin. After a surface with the recess 1 of the solid molded item 2 is roughened by etching, catalyst is provided and then chemical plating is applied for forming the conductor circuit 4 in a recessed surface.
