IPC: H01L31/04
Filed: 1990-11-26
Abstract: PURPOSE:To enable a pair of main electrodes to be formed by screen printing technology by a method wherein n<+> layer is formed by a high concentration impurity diffusion step on the whole rear surface of a p-type silicon substrate and then this n<+> layer is formed in an insular convex shape by a selective etching step before a p<+> type low concentration impurity diffusion step is performed on the whole surface. CONSTITUTION:N<+> layers are formed on both surfaces of a p-type silicon substrate. Next, an acidproof mask is printed on the other surfaces by screen printing. Next, the phosphorus glass on the non-resist part is removed using fluoric acid and then the resist is removed using a solvent. Next, boron bromide is diffused to forma p<+> layer 15. Next, after removing boron glass, boron silicide skin using fluoric acid, the p-type silicon substrate is oxidized in an oxygen atmosphere to form oxide films 2, 3. Next, in order to form electrodes by the screen printing, the substrate is printed with Ag paste containing several % of Al to be baked in a compound air atmosphere so that the Ag paste may penetrate the oxide film 3 to form an electrode in contact with an n<+> layer 16 and another electrode 6 in contact with a p<+> layer 15. Resultantly, it is confirmed that the whole part of the electrodes 5, 6 is kept within the alignment precision range of + or -150mum.

Inventor: OTAKE KIMITAKA
IPC: B23B31/39
Filed: 1987-12-16
Abstract: PURPOSE:To prevent a pawl of being mounted on a chuck in the faulty, improper, and loose manner by providing both a means which detects the position of the pawl by bringing a touch sensor into contact with the pawl of the chuck and a means which detects scatter in position of the pawl by bringing the touch sensor into contact with the pawl several times. CONSTITUTION:A chuck 3 has the automatic pawl replacement function by which a plurality of pawls 4 are automatically replaced by robot machine 15. Upon receiving a pawl measurement start signal from a central controller, the touch sensor 14 attached to a tool post 4 is moved to the axis of a spindle base 2 or near it and then toward the pawl 4 until restricted to a contact point therewith, at which a touch signal is sent to the central controller to have a pawl position determining means determine whether the pawl is mounted in the specified position or not. By making several contact of the touch sensor 14 with the pawl 4, a position variation detecting means detects the scatter in pawl measuring point, whereby judging whether the precision in the mounting position of the pawl 4 is within the pawl position tolerance. The mounting of a wrong pawl which is not suitable for a work and the inaccurate and loose mounting of the pawl may be found to prevent an accident.

IPC: G01R33/383
Filed: 1989-12-08
Abstract: PURPOSE:To obtain a fresh image by mounting magnetic flux preventing permanent magnets on the peripheral sides of a permanent magnet and a pole piece. CONSTITUTION:A pole piece 2 is mounted for the purpose of making a magnetic field at the center of an air gap formed of opposed permanent magnets 1 uniform. Yokes 3 are formed in a disc shape, and four posts 4 are uniformly disposed between the upper and lower yokes 3. Magnetic flux leakage preventing permanent magnets 5 are mounted on the peripheral sides of the magnets 2 and the pieces 2. In this case, the poles of the magnets 1 and the pieces 2 at the sides in contact with the peripheral sides are so magnetized as to be different from the poles in contact with the yokes 3. Accordingly, a magnetic flux amount to be leaked from the peripheral sides of the magnets 1 and the pieces 2 to the yokes 3 through a space can be reduced. Thus, the magnetic flux amount which passes the opposed pieces from the pieces is increased. In this manner, a central magnetic field intensity is improved to obtain a necessary signal for obtaining a fresh image.
