Title: Method for extracting inner point of polygon
Inventor: MURANO TOMOMITSU
IPC: G06F17/50
Filed: 1984-04-13
Abstract: PURPOSE:To extract an inner point rapidly and exactly by using the phenomenon that a triangle having the centroid to be an inner point of any polygon is included in a triangle formed by three continuous vertexes of the polygon. CONSTITUTION:A triangular surface determining circuit 23 determines three continuous vertexes in accordance with polygonal surface model data received from a surface model circuit 21. A triangular centroid calculating circuit 24 finds out the centroid of the determined triangle to fix the centroid as a candidate inner point. Then, an inside/outside deciding circuit 25 decides whether the candidate inner point exists in an area determined by the polygonal surface model data or outside the area. If the candidate inner point is decided as an outer point, the processing is transferred to the circuit 23, and in case of an inner point, a surface normal determining circuit 22 determines the surface normal.

Abstract: PURPOSE: To increase the efficiency of a winding operation to enhance the productivity and quality of a deflection yoke by forming a die consisting of outer and inner dies, dividing a top into two, i.e., small and large ones, and securing both of the tops in the inner die. CONSTITUTION: To wind an auxiliary deflection coil 20 (shown in Fig. (a)), the end of a small dowel 43 is fitted into a dent 48B, and an outer die 41 and an inner die 42 are combined while a gap several millimeters larger than a final closed state exists therebetween. In that state, however, the end of a large dowel 44 does not fit into a dent 48, and a clearance 49 exists between the dowel 44 and the outer die 41. As the inner die 42 is turned slowly about an axis of rotation X-X by means of a rotating shaft 47, the left outer die 41 is moved accordingly and turned about the axis of rotation X-X, and a coil is wound on the dowel 43 through the clearance 49 and wound onto a coil portion 20. Next, the outer die 41 and the inner die 42 (in Fig. (b)) are further brought close to each other and closed, and the dowels 43, 44 have their ends fitted into the dents 48B, 48A respectively.  The dies are rotated at high speed about the axis of rotation X-X by the shaft 47 to wound a main deflection coil portion 10 on the outer peripheries of the dowels 43, 44.

Title: Memory card
Inventor: SUEOKA KAZUHIKO
IPC: G06K19/07
Filed: 1987-03-27
Abstract: PURPOSE:To improve the efficiency of a backup battery by pulling up a memory IC control terminal at the time of an external connection and pulling down the terminal when the battery is disconnected from the outside, and thus ceasing a current from the backup battery to the IC card input terminal. CONSTITUTION:Memory IC control terminals L1-Ln are connected from external equipment to a power supply line 2a through pull-up resistances R1-Rn. The power supply line 2a is connected to an earth terminal 3 through a pull-down resistance R, so when a memory card is disconnected from the external equipment, the memory IC control terminals L1-Ln are all placed in a pull-down state to obtain constitution immune to external noise. Further, the pull-up resistances R1-Rn and pull-down resistance R are on the anode side of a diode D1, so no current flows from the battery B to the input terminal of the memory IC. Thus, the battery B is used only to back up the IC and the efficiency of the battery B is improved.

IPC: H01M10/05
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To improve adhesiveness with a carbon layer by providing the surface of copper foil with a recessed part and or a projecting part. SOLUTION: Recessed parts or projecting parts are formed on the surface of copper foil for a negative collector, and movement of a carbon layer on the surface of a copper material is restrained to prevent separation of the carbon layer.

Preferably, depth of the recessed parts and height of the projecting parts are not shorter than 5 μm, and are shorter than a thickness of the carbon layer formed on copper foil. When it is larger than the thickness of the carbon layer, the projecting parts project out of the carbon layer, Li ions are electro-deposited onto the projecting parts during charge, and therefore, charge becomes difficult.  In addition, preferably, array of the recessed parts and the projecting parts for the copper foil is continued in a described direction such as the width direction, length direction, tilting direction of the copper foil. Forming of the recessed parts and the projecting parts can be performed in an etching treatment or roll machining.
