Title: Manufacture for thin film resistance device
Inventor: MISAKI KOUICHIROU
IPC: H01L21/822
Filed: 1984-04-25
Abstract: PURPOSE:To omit one photo resist process to be conducted for opening a contact window and to simplify the manufacturing process by a method wherein a thermal treatment is performed on the photo resist and a thin film resistor is covered with the photo resist including its side surfaces too. CONSTITUTION:A photo resist film 208 is left on a part alone, where a resistor of a thin film, such as a thin film of Ni, Cr and so forth, is to be formed, then an etching is performed on the thin film of the resistor using the photo resist film 208 as a mask to form the thin film resistor 209. A thermal treatment is performed to dull the photo resist film 208 like a photo resist film 208'. At this time, the photo resist film 208' is formed in a form to completely cover the thin film resistor 209 including the side surfaces of the resistor 209 too. In this condition, a thermal oxide film 205 made to expose in a window 207 for a second contact is removed using an etching liquid of the hydrofluoric acid series. The photo resist film 208' is removed and an aluminum electrode is formed on each of a P type diffusion layer 202 and the thin film resistor 209.

IPC: G03F1/00
Filed: 1978-07-12
Abstract: PURPOSE: To solve stencil problem by utilizing the diffraction effect by densely arranging many holes at a light permeable area in a mask pattern in such a way that diffraction waves from adjonining holes overlap each other.  
     CONSTITUTION: Many small holes, with a diameter of 2 μm for instance, are densely arranged at a light permeable area in a mask pattern in such a way that diffraction waves from adjoining holes overlap each other so that the entire light permeable area of the mask pattern can be exposed by utilizing the diffraction effect. As for the shape of the holes, a circle with a nife-edge section is most desirable in order to apply the diffraction effect efficiently. When holes that have the same diameter are to be arranged, they should be spaced irregularly, and when they are to be equally spaced diameters of the holes should be changed irregularly so that the groupe of the holes does not form a plane diffraction grid.

Title: Copying machine
Inventor: FUJIMOTO KATSUYA
IPC: G03G15/00
Filed: 1978-07-10
Abstract: PURPOSE: To perfectly eliminate the failure of copying by electronically controlling the light transmission quantity of original paper and automatically controlling the copying speed to the optimum speed conforming to the quality of the original paper.  
     CONSTITUTION: The quantity of light which a photo detector 3b receives from a projector 3a changes with the quality of original paper 4a because the light transmission quantity of photosensitive paper 5 is practically constant. Hence, if the light transmission quantity by the photosensitive paper is beforehand set in an amplifier 7a, the light transmission quantity of the original paper may be measured. The signal 8 proportional to the quantity of received light of the photo detector 3b is compared with the signal proportional to the revolving speed of a paper-feed motor 1 at the current point from a tacho generator 6 in the amplifier 7a. If the signal 8 is larger than the signal 9, the output 10 of the amplifier 7a becomes large and causes the motor 1 to be accelerated by a motor control circuit 7b. When the signal 8 is smaller than the signal 9, the above are reversed and therefore the optimum copying speed complying with the light transmission quantity of the original paper 4 may be obtained. Hence, the failure in copying may be perfectly eliminated and the wasteful use of the photosensitive paper eliminated.

Title: Fixing device of magnetic head
Inventor: INOUE YOUICHI
IPC: G11B5/53
Filed: 1982-05-21
Abstract: PURPOSE:To reduce the variation of projecting degree which is due to the revolution of a head base, by using a countersunk screw and a washer having its inner diameter part chamfered properly at the fixed part of the head base. CONSTITUTION:A washer 23 having its inner diameter part shamfered is used in order to fix a head base 8 having a center hole 8A by a screw. Then the base is attached at the lower part of an upper cylinder 2 by means of a countersunk screw 22. When the rotational moment produced by an eccentric pin 16 is applied to the base 8, no slip is produced on a contact surface 25 between the base 8 and the washer 23 owing to the large friction force. Then a slip is produced at a linear contact part 24 between the screw 22 and the washer 23. As a result, the base 8 rotates around the center position of the screw 22. Therefore, the attachment error is eliminated in the assembling stages if the accurate processing is applied only to the position of a female screw of the cylinder 2. This device facilitates a adjustment.
