A lift mechanism of a die set apparatus includes a guide pin, a linear motion guide member, a first washer, a second washer, a first coil spring, and a second coil spring. A first positioning portion and a second positioning portion control a first end turn portion and a second end turn portion from moving in a radial direction of the guide pin in a state where a first gap is formed between the first coil spring and the guide pin. A third positioning portion and a fourth positioning portion control a third end turn portion and a fourth end turn portion from moving in the radial direction of the guide pin in a state where a second gap is formed between the second coil spring and the guide pin.

Die set apparatus

A load beam includes a pair of flange bending parts including first bending parts, and a second bending part extending in a width direction. A first cross-section part extends in the width direction of the load beam passing through welding parts. The first cross-section part is warped up toward the flange parts. A second cross-section part extends in the width direction passing through a different position from that of the welding parts. The second cross-section part has a lesser height difference as compared to the first cross-section part. A die is used when bending the second bending part. The die includes a first relief part including a first inclined surface and a second relief part including a second inclined surface in both sides of the supporting surface.

Disc drive suspension including load beam having different cross-sectional shapes at welded and non-welded parts thereof

A disk drive suspension of the embodiments includes a load beam, and a flexure including a mounting portion on which a slider is mounted and overlapping with the load beam. The load beam includes a tab further extending than the mounting portion longitudinal direction of the load beam. The tab is shaped in an arc such that a central portion in a lateral direction protrudes with respect to both end portions in the lateral direction, in the load beam. Each of the both end portions includes a flat surface parallel to the lateral direction.

Disk drive suspension including a load beam with an arc-shaped tab, disk drive, and disk drive suspension manufacturing method

A positioning apparatus has a pilot holder having a hold face, a positioning pin having a tapered tip and supported by the pilot holder so that the tapered tip protrudes from the hold face of the pilot holder, a pad having a pad face that opposes the hold face of the pilot holder, and a movable member having a stop face that opposes the positioning pin and a relief hole for avoiding the tapered tip of the positioning pin from hitting the stop face, the movable member resiliently supported on the pad. The pilot holder and the pad in which the thin plate material is set between the hold face and the pad face relatively move to insert the tapered tip of the positioning pin into the positioning hole of the thin plate material. The stop face is flush with or protruding from the pad face of the pad.

Positioning apparatus and pressing apparatus

Disclosed are a kinematic-simulation method and a kinematic-simulation apparatus which enable simulation of the behavior of a mechanism by using a CAD figure by a simple operation. The kinematic-simulation method includes an interference operational method according to which a translation is continued until the figure associated with the operation (the driver) comes into contact with the figure associated with interference (the stop). When defining the driver translation, an interference operation is defined, whereby a translation amount (an angle or a vector) can be calculated within a computer. Accordingly, an operator does not input a rotation angle for rotation or a vector for translation.

Kinematic-simulation apparatus and kinematic-simulation method with

The present invention relates to a graphics processing apparatus for plotting three-dimensional graphics by using a grid, and to a method of use of the apparatus. An arbitrary plane grid is displayed on a display screen, the displayed grid is variously changed and the three-dimensional graphic is plotted using the changed grid. The possible changes of the grid include a grid translation, a grid spacing change, a grid rotation, the selection of a grid display/non-display mode, coincidence/non-coincidence of the reference points of the graphic with the grid, and the like. Also, the apparatus executes a corner processing, including arc processing and straight line processing. In the arc processing, the corner processing is executed by selecting two straight lines and inputting a radius to define a corner joining the two lines; and in the straight line processing, the corner processing is executed by selecting two straight lines and inputting the length and angle of a line segment to join them.
