Title: Display device
Inventor: HONJO TERUBUMI
IPC: G09F9/40
Filed: 1986-06-11
Abstract: PURPOSE:To increase the density of a picture element array and to improve the resolution of a display scope by arranging a transmitted light control element between the inclined end faces of one end part of a platelike light leading-in body and one end part of a light leading-out body to constitute a window for observing a display scope and contracting a dead space. CONSTITUTION:Light beams radiated from a light source for back light are transmitted through transparent driving wired layers 61-6n+1 and drawing wired layers 41-4n+1, made incident from a vertical end part 1b of the light leading-in body 1 into its inside, advanced in the light leading-in body 1 in the Z direction, and then made incident upon an one-dimensional liquid crystal element 3. Transmitted light T transmitted through the light leading-in body 1 is advanced through the inside of the light leading-out body 2 and then projected to the outside from its vertical end part 2b. The vertical end part 2b constitutes a window for observing the display scope of the transmitted light control element arranged on one end part 2a of the light leading-out body 2. Thereby, the dead space in the display scope is reduced by sin theta times when an inclination of the inclined end faces of the light leading-in body 1 and the light leading-out body 2 from the Z axis id defined as theta.

Title: Iron-base alloy and its production
Inventor: UENO TAISEI
IPC: C21D8/00
Filed: 1992-04-28
Abstract: PURPOSE:To produce an iron-base alloy free from variance, having high fatigue strength, and excellent in reliability and machinability by applying rolling to a cast iron-base stock at a stress parallel to plastic flow direction and then performing specific heat treatment, rapid cooling treatment, and austempering treatment. CONSTITUTION:An iron-base alloy stock consisting of matrix structure and spheroidal graphite is cast. This stock is subjected, preferably, to surface cleaning, and primary cementite, if contained, is decomposed by heating. Then the stock is heated up to a working temp. and subjected to plastic working by rolling or forging. At this time, the direction of the principal stress applied to a product is regulated so that it is in parallel with the plastic flow direction of the material, and microporosities are pressed and graphite is formed into spindle or sheet-like shape. The resulting worked material is heated up to a temp. not lower than the austenite region temp., preferably 825-980 deg.C, cooled rapidly, and then reheated to undergo austempering treatment. By this method, the graphite-containing iron-base alloy having >=20% plastic working rate, containing <=20% retained austenite, and composed of dual phase mixed structure of bainite and austenite can be obtained.

Title: Manufacturing apparatus for multilayer printed board
Inventor: KYOI MASAYUKI
IPC: H05K3/46
Filed: 1991-06-07
Abstract: PURPOSE:To make thickness of a board after adhesion uniform and to easily form a multilayer printed board having no interlayer deviation and no interlayer bubble by reducing in thickness a hot plate and eliminating generation of warpage of a hot plate due to insertion of a jig plate in steps of heating and pressurizing. CONSTITUTION:An apparatus for manufacturing a multilayer printed board, has two jig plates 2, 3 for holding a plurality of printed board 1 laminated through adhesive, a hot plate 14 for heating and pressuring a jig plate 4, and a support structure for holding the plate 14. The thickness of the plate 14 formed of an upper hot plate 12 and a lower hot plate 13. In this case, if a ratio of thickness to width of the plate 14 is 1/50 or less, it is sufficiently thin. Thus, a temperature distribution of the hot plate when the plate 4 for holding a laminate is inserted between the plates 14 becomes ignorably small, and no warpage of the plate 14 occurs inward. Even if warpage tends to occur, the hot plate is thin and low rigid, and hence it does not affect influence to the thickness of the board.

Title: Ink dot printer
Inventor: IIJIMA HOUCHI
IPC: B41J2/305
Filed: 1983-07-26
Abstract: PURPOSE:To ensure a clear printing even under a continuous driving of needles by forming a magnet section at the tip of a plurality of needles for transferring a magnetic ink to a recording section. CONSTITUTION:Tips 16 of needles 15 are arranged vertically in one row and a magnet section 17 is formed at the end thereof. The magnet section 17 is magnetized with magnetic poles arranged along the axis of the needles 15. When an electromagnetic coil 18 is electrically energized, a magnetic ink 22 is attracted into a magnetic field slit 19 to form a magnetic ink film 24 while attaching to the tips 16 of the needles 15 positioned within the magnetic field slit 19. When the printing of a character or the like by gathering dots requires a continuous driving of the same needle 15, the magnet section 17 provided at the tips 16 of the needles 15 allows returned magnetic ink 22 to creep around and attach to the ends thereof quickly. This keeps the amount of the magnetic ink 22 so uniform as to ensure a clear printing.
