  • Publication number: 20140300606
    Abstract: A drawing device includes an input unit, a first vector calculation unit, a second vector calculation unit, and a display control unit. The input unit accepts user input. The first vector calculation unit calculates a first vector whose starting point is one of the endpoints of a hand-drawn line displayed on a display unit based on the user input. The second vector calculation unit calculates a second vector whose starting point is the one endpoint based on the shape of the hand-drawn line in the vicinity of the one endpoint. The display control unit determines whether to extend the hand-drawn line or to erase at least a portion of the hand-drawn line with the one endpoint as the starting point based on the first and second vectors and also performs the extension or at least partial erasure of the hand-drawn line based on the user input.

  • Publication number: 20140300588
    Abstract: A drawing device includes an input unit, an object controller, and a display controller. The input unit receives user's input. The object controller controls a display unit to display a position instruction object movable based on user's input when a line displayed on the display unit is selected. The display controller moves an end point of the selected line along the selected line based on a movement amount of the position instruction object. Further, the display controller sets a part of the selected line between end points before and after the movement as a part to be set for display deletion.

  • Publication number: 20140123053
    Abstract: A display terminal device displays objects arranged in a virtual space on a display device. The display terminal device generates an object identifier indicating an object entered by a user such that the object identifier includes a user identifier. The generated object identifier is, along with the object, transmitted to a drawing device. The display terminal device saves an object and an object identifier received from the drawing device until receiving the transmitted object from the drawing device. A display screen of the display device is refreshed to display the object received from the drawing device.

  • Patent number: 7777991
    Abstract: A head gimbal assembly (HGA) has an improved interconnection between a head slider and a suspension of the HGA. The interconnection is achieved by using a reverse surface of an air bearing surface of the head slider as bonding surface to provide more space for arranging more slider electrical bonding pads thereon. The head slider is mechanically and electrically connected to the suspension at the bonding surface to have good performance on shocking conditions. The suspension further has an attitude control layer located between the head slider and the suspension. The attitude control layer serves as a datum plate for the head slider lying thereon and supporting the head slider so as to ensure the head slider a good attitude and reduce variation of slider flying height. The present invention also discloses a magnetic disk drive with the improved HGA and a fabricating method for the HGA.

  • Publication number: 20090277591
    Abstract: An auxiliary fixture for debonding sliders from an exposure jig and receiving the sliders includes a debonding tray. A top surface of the debonding tray forms a plurality of slider pockets arranged in an array. Every two adjacent slider pockets in every column of the array are separated by an interval wall such that every interval wall corresponds to one slider pocket. One side of each interval wall that forms an inner wall of the corresponding slider pocket is an incline such that the interval wall has a structure tapering from the bottom up. The inclines of the interval walls in the same column of the array incline to the same side and the inclines of the interval walls in two adjacent columns of the array incline to opposite sides such that every two adjacent interval walls in every row of the array form side walls of each other's slider pockets. The present invention also discloses a method for manufacturing sliders with the auxiliary fixture.
