Title: Manufacturing and forming method for air filter of automobile
Inventor: HUANG CHI-RUNG
IPC: F02M35/02
Filed: 2001-03-01
Granted: 2001-11-11
Abstract: This invention provides a manufacturing and forming method for air filter of automobile, which is achieved by a preset mold composed of upper, intermediate, and lower mold holder during manufacturing and forming. The upper and lower mold holder are provided with protruding partitioning plates staggered with relative interval, depending upon the repeated folding type with preset interval of the cotton filter sheet. The plate shaped cotton filter sheet is placed on the protruding partitioning plate of the lower mold holder, so that the cotton filter sheet is squeezed to be formed as repeatedly folded shape spaced at interval by the matching up of the interval of the protruding partitioning plate when upper and lower mold holders are closing. Afterwards, the upper, intermediate, and lower mold holders are heated to an appropriate temperature, and then robber raw material is injected from the upper mold holder in to the mold holder to for robber frame wrapping around the cotton filter sheet. Therefore, an integratedly formed air filter for automobile can be obtained by only one close mold and open mold process, so as to achieve the advantages of increased production efficiency, better structural strength, high quality, and lower cost.

Title: Optical pickup assembly
Inventor: CHOI HAN-KOOK
IPC: G11B7/09
Filed: 2001-03-19
Granted: 2002-08-11
Abstract: An optical pickup assembly is provided which includes: a base; an objective lens including a body portion, and a lens portion built-in to the body portion; a suspension whose one end is fixed to the body portion and whose the other end is fixed to a holder, for supporting the objective lens such that the objective lens is movable; a coil member formed at the sides of the body portion of the objective lens; permanent magnets mounted on the base, opposite to the coil member; and yokes for guiding magnetic flux generated by the permanent magnets. In the optical pickup assembly, the objective lens is constructed such that the body portion serving as a bobbin is combined with the lens portion, thereby reducing the weight of the moving part. As a result, the moving part can sensitively accelerate with application of a voltage. In addition, the moment of inertial of the moving part decreases due to the reduced weight thereof, and the secondary resonance frequency of the moving part is increased due to the structure of the objective lens whose body itself serving as a bobbin. Thus, the optical pickup assembly can efficiently accelerate at a voltage level, so that it can be effectively used for high-speed and high-density optical recording/reproduction systems.

Title: Optical disk
Inventor: MIYAMOTO HARUKAZU
IPC: G11B7/24038
Filed: 2001-07-26
Granted: 2004-02-21
Abstract: In the record type multilayer optical disk, interlayer crosstalk is large in an ID or address data region, a boundary region between a recorded part and an unrecorded part, etc. Locations of an information recording unit region and of ID or address data of adjacent plural tracks on a recording medium are configured so as to be shifted in the circumferential direction by 5 mum or more. Since an effect from a layer that is not selected can be remarkably reduced in the multilayer optical disk, multilayer recording/reproducing can be realized in the record type optical disk. Moreover, since pieces of the ID or address data do not center at the same position in reference to the circumferential direction, the effect of distortion that is generated on the disk substrate and the recording layer at the time of optical disk formation or multiple overwriting can be minimized, and design and fabrication tolerances of the optical disk are extended, and as a result the media can be provided with a low cost.

Title: Self-unloading magnetic coupler
Inventor: KILLEN RICHARD
IPC: H02K49/10
Filed: 2002-06-12
Granted: 2003-05-11
Abstract: In a magnetic coupler, a pair of magnet rotors is slid ably mounted on rods. Ferrous material on the conductor rotors attracts the permanent magnets in the magnet rotors. Under static or relative static conditions, the attractive force urges the magnet rotors toward the conductor rotors to create a minimum, operational air gap therebetween. When there is a significant relative rotational velocity between the magnet rotors and the conductor rotors, a repulsion force urges the rotors apart. During start-up, latch arms retain the magnet rotors apart from the conductor rotors by a larger, soft-start air gap. During operation, centrifugal force moves the latch arms out of their active position. If the rotational speed of the load shaft decreases rapidly during operation, the magnet rotors move apart from the conductor rotors by a still larger, fully disengaged air gap.
