Title: Method and forming machine for manufacturing screwdriver having a nut
Inventor: HUANG YING-JIE
IPC: B21K5/16
Filed: 2000-04-01
Granted: 2001-09-11
Abstract: This invention is related to a method and forming machine for manufacturing screwdriver having a nut, that uses a forging forming machine to integrally forge a hexagonal nut with an enlarged diameter on a screwdriver bit. The hexagonal nut is to be engaged by a hexagonal socket for driving its rotation so as to increase the rotational torque of the screwdriver for tightening a screw. The invention is characterized in that, four pressing molds of the forging forming machine are used to overcome the problems of having great difficulty in forming two segments of different diameters on a single rod body found in conventional forging process, such that the hexagonal nut is gradually expanded and formed by being sequentially molded in the four pressing molds, thereby reducing the plastic deformation pressure required in each step, such that the diameters of the hexagonal nut and the screwdriver bit are significantly different to provide the rotational torque required for locking the screw.

Title: Apparatus and process for introducing sensitive into thermoplastic synthetic plastics material
Inventor: BACHER HELMUT
IPC: B29B7/00
Filed: 2000-06-20
Granted: 2002-05-21
Abstract: An apparatus for introducing sensitive additives, in particular additives that are sensitive to a shearing action or kneading action, into thermoplastic synthetic plastics material comprises a plasticizing zone (47) in which a plasticizing screw (8) is bearingly supported within a housing (7) and plasticizes the synthetic plastics material. The plasticizing screw (8) conveys the plasticized material towards a screw section (20) that forms a relief zone (49). Within the relief zone (49) at least one additive is introduced into the plasticizing synthetic plastics material via at least one conduit (24) and is mixed with the plasticized plastics material by means of a screw (20). Between the plasticizing zone (47) and the relief zone (49) there is disposed within a damming zone (50) a damming body (14) that rotates together with the plasticizing screw (8) and limits the flow of the plasticizing synthetic plastics material flowing along it. When seen in conveyance direction of the plastics material, at least one conduit (16) for plasticized synthetic plastics material branches off in front of this damming body (814) that by-passes the damming body (14) and merges behind the mouth (49) of the conduit (24) for the additive into the relief zone (49) or into a housing zone (31) disposed behind it. Thereby, the introduced additives are better wetted by the synthetic plastics material.

Title: System and method for double buffering graphics image data with compressed frame buffers
Inventor: NARAYANASWAMI CHANDRASEKHAR
IPC: G06T1/60
Filed: 1997-05-28
Granted: 2003-08-21
Abstract: The present invention allows the frame buffer to be dynamically reconfigurable during the processing of graphics data. Lower resolution double buffer mode is used when objects are moving, and higher resolution single buffer mode is used when objects are stationary. The user gets the benefits of double buffering while objects are in motion, and the benefit of a higher quality image when objects are stationary. No image tears appear in this case because the graphics processing system redraws the exact same image when motion ceases, however the image has more bits per pixel. The visual effect is that the picture becomes clearer when motion ceases. The graphics processor quickly switches frame buffer modes during execution, and are is constrained to specifying one mode at the start of processing.

Title: Power supply circuit for liquid crystal
Inventor: SHIMODA SADAYUKI
IPC: G09G3/36
Filed: 2000-09-14
Granted: 2002-10-21
Abstract: There is provided a power supply circuit in which, with respect to common side drive voltages VH, VL, and V1 and segment side voltages V2 and V1, the relation of VH-V1=V1-VL is realized with high precision, and the relation of V2-V1=V1-Vss is realized with high precision. The segment side voltage V2 is halved by two resistors to generate the voltage V1. At this time, either one of the two resistors is trimmed, so that V2-V1≠V1-Vss, which is caused by an offset voltage of a buffer circuit constituted by an operational amplifier and ratio precision fluctuation of the two resistors, is corrected, and the relation of V2-V1=V1-Vss is realized with high precision. Besides, a positive power supply of the buffer circuit constituted by the operational amplifier is adopted from the segment side voltage V2, so that the power loss of the buffer circuit constituted by the operational amplifier can be suppressed to (V2-V1)x(consumed current of liquid crystal panel).

Abstract: This invention provides die-casting aluminum alloys used for extra-thin (0.6-1.2 mm) parts for 3C products. The first type is an aluminum-silicon-magnesium-manganese alloy primarily containing 10.0-15.0 weight percent of silicon, 0.25-0.50 weight percent of magnesium and 0.60-1.40 weight percent of manganese. The second type is aluminum-silicon-copper-manganese alloy primarily containing 10.0-15.0 weight percent of silicon, 3.0-4.0 weight percent of copper and 0.60-1.2 weight of manganese. Both types of alloys individually contain no more than 0.05 weight percent of strontium, no more than 0.5 weight percent of iron and no more than 0.25 weight percent of titanium. Fluidity (mold-filling capability) of these two alloys is at least 20 percent better than the conventional alloy. Under high pressure die-casting condition, a casting piece with wall thickness of 0.6-1.2 mm can be achieved. Therefore, the inventive alloys are particularly suitable for the application of 3C product casing. As the production cost of the inventive alloys are 15-25% lower than that of magnesium alloy, the inventive alloys will replace the latter.
