  • Patent number: 6951892
    Abstract: A continuous output system makes paper coating by combining an emulsifier with ASA particles having a mean average size in the low to sub-micron region. A turbine, pump, blender or other device exposes the ASA to a number of repeated episodes of high shear until the resulting ASA is in the form of particles having a mean average diameter in approximately the 1? range. The measure of the amount of high shear is identified by an energy factor index. A system for cooling the ASA enables the processing without causing a hydrolyzing of the ASA, even when a heated cooked emulsion is used.

  • Patent number: 6527568
    Abstract: A card connector comprising a U-shape frame of a pair of guide arms of synthetic resin, a metallic bridge connecting the guide arms to each other to form a U-shape, and a connector part fit to the U-shape frame beneath the metallic bridge. A lever and a slider plate of an eject mechanism are mounted on the bridge. One of the guide arms is provided with an ejector button to be slidable thereon. In order to prevent the PC card from inserting into the card connector with a state where the PC card is reversed in front and rear and/or upside down, one of the guide arms is formed with a thin polarity key and the other of the guide arms is formed with a thick polarity key. Both the guide arms are symmetrically constituted except the polarity keys and are replaceable to each other.

  • Patent number: 6504334
    Abstract: In circuitry for driving a motor 9 by PWM (Pulse Width Modulation) control. a pulse sequence Spwm is generated on the basis of a triangular wave TR that is control led by a capacitor. The pulses of the pulse sequence Spwm are counted in synchronism with position signals U1, V1 and W1 output from position sensing means, which is responsive to the angular positions of the motor 9, so that a duty modulation signal Sduty-b is generated for reducing noise ascribable to the rotation of the motor 9. An exciting pulse generating circuit 8 switches a MOSFET (Metal Oxide Semiconductor Field Effect Transistor) circuit 11 with gate signals Q1P through Q3P and Q1N through Q3N.

  • Patent number: 6437835
    Abstract: A system for transferring video data includes a difference detector for detecting the difference between a current field information and the preceding field information. The preceding information is obtained from an entered interlaced video signal. An interpolator generates current display frame information in response to an interpolation based upon the current filed information with regard to an area of the video signal in which there is a difference value between successive fields that exceeds a predetermined threshold value. The interframe difference between the current display frame information and preceding display frame information is detected by the difference detector. Only the interframe difference is transferred over a system bus to enable a frame display to be presented on non-interlacing display device.

  • Patent number: 6430092
    Abstract: When a /RAS (/row address strobe) signal is input to a memory device, a control logic of the memory device issues an internal /RAS signal corresponding to the /RAS signal and then a row decoder drives a selected wordline in response to the internal /RAS signal. A predetermined time internal passes from the issuance of the internal /RAS signal to the drive of the selected wordline, depending upon a circuit layout of the memory device, skew and so forth. The predetermined time interval is utilized for a time of pre-booting at a booting circuit.

  • Patent number: 6421207
    Abstract: In a contact type magnetic disk drive, a suspension spring or a load beam spring has a length smaller than 5 mm inclusive. This successfully reduces the amplitude of vibration to occur during seek. Also, a magnetic head slider has a mass of greater than 2 mg inclusive and is urged against the disk medium by a load of less than 1 g inclusive, so that a mean wear thickness and maximum amount of jump are reduced. For the reduction of the mean wear thickness and maximum amount of jump, the disk medium may include a lubrication layer having a thickness of greater than 5 nm inclusive, or the suspension spring or the load beam spring may have its thickness sequentially reduced from the side adjoining the spring support mechanism toward the slider. The disk drive reduces the wear of the slider and that of a magnetic disk, and achieves durability and reliability as well as high-density recording.
