Granted: 1987-02-21
Abstract: Laminated polyester film is prepd. for use as magnetic record tape. Two types of polyester are prepd. by mixing inert compds. whose particle sizes are different from each other. These are pressed out together and then laminated and lengthened. Polyester film I which is not coated with magnetic material has 0.1-12micron particle size. Polyester film II which is coated with magnetic material has 0.1m micron-0.09 micron. The frictional coefficient of film II is larger than that of film I.

Title: Printer controller
Inventor: AOKI HIROYUKI
IPC: B41J5/30
Filed: 1985-01-17
Granted: 1990-04-06
Abstract: One-line data transmitted from a host CPU includes a charater and a figure.  A print and line feed controller causes a character image generator to access a character pattern memory so as to write the read character image in the line buffer.  The print and line feed controller causes generation of a figure image which is then ORed- written on the character image.  As a result, one-line character and figure data can be printed with one scanning operation.  Figure data parameters are stored in the parameter area in the internal memory.

Abstract: A plastic working apparatus to  make  T-shape  tubes  of  gas lighters comprises a cutting die, a first die and a second die.  A round bar made of copper alloy is cutted by the cutting die  to  a length in order to have a volume equivalent to  the  volume  of  a T- shape tube, and is sent to between both dies being  opposite  to each other. Then the round bar of cutting is  transformed  into  a T-shape  tube  through  successive  plastic  forming  steps.  This plastic forming method is simpler and  cheaper  than  die  casting process used before in  making  T-shape  tubes  of  gas  releasing valves for lighters.

Title: Tape cassette
Inventor: TANAKA MASATO
IPC: G11B23/28
Filed: 1991-09-18
Granted: 2000-03-15
Abstract: A tape cassette has one or more manually settable slider elements that are detected to prevent erroneous erasure of information recorded on the cassette. The or each slider (50) slides in a through hole (31) in the cassette case (2, 3) and includes stops (53a, 53b) that limit the travel of the slider element (50) by co-operating with protrusions or shoulders that are formed by the respective half cases (2, 3) making up the cassette case. The slider element (50) also includes a click-stop protrusion (51) that co-operates with a protrusion (32) in the through hole (31) that is formed in only one of the two half-cases (2, 3). The slider element (50) further includes a through slot (55) that permits deformation of the slider element (50) as the click-stop protrusion (51) goes over the protrusion (32) in the through-hole (31), thereby requiring less force to move the element. The stops (53a, 53b) can be formed by two spaced apart protrusions that also permit deformation of the slide element as the click-stop protrusion (51) travels past the protrusion (32) in the through-hole (31). <IMAGE>

Title: Method of manufacturing glass fiber reinforced thermoplastic lamellar
Inventor: KIM KWANG-TAE
IPC: B29D7/00
Filed: 1991-12-30
Granted: 1994-10-24
Abstract: The method manufactures the glass fiber reinforced thermoplastic plate body used for light-weighted and mechanically strengthened industrial parts such as automobile parts, construction materials, or machine parts. The method comprises the steps of: mixing the thermoplastics powder and the glass fiber within the temperature range of 10-100 deg.C lower than melting points under the flow of nitrogen gas; inserting the mixture into between seats made from the same thermoplastics, and heating/ pressing them; managing them within the temp. range of melting point -20 deg.C to melting point +10 deg.C; abruptly cooling them.

Title: Crankshaft of v-type 6-cylinder internal combustion engine
Inventor: BAEK SUNG-YUN
IPC: F16F15/24
Filed: 1991-12-30
Granted: 1996-09-04
Abstract: The crankshaft of the V-type 6-cylinder internal combustion engine is for reducing the vibration of the engine and the pressure applied to the crank journal by offsetting the couples of inertia and unbalanced inertia. The crankshaft have the six balancing weights arranged symmetrically to the center of the axle almost perfectly.
