Title: Calculating system for internal point of arbitrary polygon
Inventor: SAKURAI TAKESHI
IPC: G06T11/20
Filed: 1987-03-13
Abstract: PURPOSE:To derive an internal point of an arbitrary polygon by calculating an address to be read out from a refresh memory, from each apex of a polygon by a CPU, reading out a data by a graph display part, and calculating the internal point. CONSTITUTION:A graph display control part 4 draws a contour of a polygon by a line kind designated to designated color memories R, G and B 5, by an instruction from a CPU 2. Subsequently, on a memory W 8, a copy of a contour of the polygon is drawn by a full line. The CPU 2 derives a Y coordinate of one or plural lines being unequal to any apex, from a range of the minimum and maximum values in the Y direction of each apex of the polygon. Subsequently, the total number of straight lines in which the (y) coordinate crosses a straight line for constituting analogously the polygon is derived. Next, the maximum and minimum values in the X direction of each apex are derived, and in its range, a data on the corresponding memory W 8 is read out in accordance with the (y) coordinate, and the total number which becomes '0'   '1' is derived. Subsequently, that which is equal in the total number of straight lines for crossing the straight line of the previous polygon constitution, and the total number which becomes '0'   '1' on the memory W 8 is derived, and an address which becomes '0' z '1' first, and becomes '1'   '0' subsequently becomes an internal point.

Abstract: PROBLEM TO BE SOLVED: To facilitate carry-in work so as to make installation work rapid by forming a frame in a vertically dividable state, and dividing the frame in a position of the same height as an uppermost stage shelf or above the uppermost stage shelf when the position of the uppermost stage shelf is in a lowest state. SOLUTION: A shelf 3 is rotated while describing a rotation locus 26 of a shelf fixing shaft at a device upper part. The shelf 3a shown by an imaginary line is positioned at an uppermost part in the device, that is, the position of the shelf in the uppermost stage is in a highest state. A frame therefore has height dimension covering the shelf 3a. The frame is vertically dividable and divided in a position of the same height as the uppermost stage shelf or above the uppermost stage shelf when the position of the uppermost stage shelf is in the lowest state, that is, in a position (divided position P) slightly above the upper face of the uppermost stage shelf. The lowest state of the uppermost stage shelf position means the aligned state of the upper face positions of the uppermost stage shelves.

Title: Slider for recording and reproducing head for magnetic disk device
Inventor: FUKUDA KATSUYUKI
IPC: G11B21/21
Filed: 1990-03-13
Abstract: PURPOSE:To prevent a damage to a disk due to contact without losing a substantial function of a floating rail by providing an auxiliary rail of a same height of each floating rail in parallel with the outside of the installing position of each floating rail at the side of a contact face of the disk and finishing an apex face of the auxiliary rail in a circular-arc cross section. CONSTITUTION:An auxiliary rail 18c of a same height of each floating rail 18b is provided in parallel with the outside of the installing position of each floating rail at the side of a contact face of a disk 2 and an apex face of the auxiliary rail 18c is finished in a circular-arc cross section. In this case, when the attitude of the slider 18 at the start/ stop of the disk 2 is unstable and an edge of a side ridge of the floating rail 18b is in contact with the surface of the disk 2 by rolling, the auxiliary rail 18c placed at the outside is first in contact with the surface of the disk 2 to block the contact of the floating rail 18b. The action of air flow is sufficient, the floating of a head 7 is made stable thereby allowing the device to enter the steady-state. Since the cross section of the auxiliary rail 18c is circular-arc, no damage is given to the disk 2 even at contact. Thus, the damage to the disk due to contact is prevented.

IPC: G02B26/10
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To reduce vibration caused in respective optical parts by vibration generated by a driving system and a light deflector in an image forming device. SOLUTION: The respective optical parts are arranged on the bottom wall 24 of an optical box 20 used for this optical scanner 18. When the scanner 18 is driven, the vibration is caused by the rotational driving of a polygon mirror 32 and propagated on the wall 24. Meanwhile, bosses 46a and 46b are integrally formed on the wall 24 of the box 20, and a prepared hole for fixing a screw is formed at the edges of the bosses 46a and 46b. Then, a cover 50 covering over the aperture part of the box 20 is tightened at the edges of the bosses 46a and 46b by screws 56. Thus, the rigidity of the wall 24 is enhanced and not only the vibration propagated on the wall 24 but also the vibration caused in the respective optical parts are reduced.

Title: Membrane switch
Inventor: ASAO TSUTOMU
IPC: H01H13/52
Filed: 1991-02-12
Abstract: PURPOSE:To smoothly carry out elastic deformation of a disc spring at the time of pressing a click plate, avoid a cracking phenomenon, and to improve the durability of the click plate by connecting the disc spring part and a skirt part to each other in a uniform distance by a plurality of supporting parts. CONSTITUTION:Since a supporting part 35 connects a disc spring part 31 and a skirt part 32 to each other in a uniform distance at about 90 deg., the periphery of the spring part 31 is kept rising all the time by the supporting part 35. When pressing operation is carried out through a key top 26, the top 26 directly touchs a click plate 30 and the spring part 31 is deformed in bending and switch contacts 23, 24 are thus electrically connected to each other. At that time, the empty space of the periphery of the spring part 31 of the click plate 30 works as an air vent and the center position of the spring part 31 is thus prevented from moving. Consequently, stress concentration is not caused on the periphery of the disc spring and cracking phenomenon can be avoided so as to improve the durability of the click plate.
