Title: Wing anchor
Inventor: MORI SEIICHI
IPC: E02D17/20
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To display nonslip effect and bind lath sufficiently by composing a wing anchor driven to hold vegetation base material on a slope of a hard rock face, of a stainless steel anchor shaft inserted through and fixed into a drilled hole drilled in the slope, and a nonslip plate. SOLUTION: An anchor shaft 11 inserted through and fixed into a drilled hole drilled in a slope is formed of corrosion resistant stainless steel into hollow bar shape. Protrusions are disposed on the surface of the anchor shaft 11 to increase frictional force between the surface and the internal wall of the drilled hole drilled in the slope so as to improve adhesion of a nonslip plate 12 to a sand base layer. A wing anchor 1 is installed on the slope, and vegetation base material is sprayed thereon so as to positively hold each wing anchor 1. Infiltration of rainwater from the top end of the anchor shaft 11 into an opening is prevented by a cover member. Material such as stainless steel is therefore reduced so as to manufacture the wing anchor 1 at a low cost, and lath is sufficiently bound so as to positively prevent detachment of locked lath.

Title: Drive circuit for cross coil movement
Inventor: NAGAMI MASABUMI
IPC: G01R5/16
Filed: 1991-07-22
Abstract: PURPOSE:To cancel a change due to the existence or nonexistence of vibration and thereby to reduce a display error by setting two kinds of SIN and COS approximation signals corresponding to input signals, respectively, and by changing a cross coil angle by selecting either of these two kinds of signals. CONSTITUTION:A determination circuit 10 determines whether a change in a control angle is in a rising direction or a falling direction by comparing voltages V inputted from a frequency measuring circuit 1 before and after a prescribed time, and controls MPX circuits 13 and 14 by its output, so as to select two approximation signals from memories 11 and 12 wherein SIN and COS signals for a rise and a fall are set beforehand. The two signals are supplied to coils 6a and 6b, through two PWMs 4 and 8 and drivers 5 and 9 and thereby a cross coil movement 6 is driven. In this case, a difference in a control angle by the SIN approximation signals for the rise and the fall is so set as to correspond to hysteresis characteristic angles of the coils 6a and 6b making up a cross coil being driven under the control, and therefore skipping of an indicator at the time of switching from the rise over to the fall or from the fall over to the rise is prevented.

Filed: 1990-08-03
Abstract: PURPOSE:To instantaneously remove adhesion between a head part and a disk even if the head part is stuck to the disk by providing this disk driving device with a heating or cooling means for heating or cooling the head part. CONSTITUTION:A heating body 7 is fixed to a head arm 5. When the head part 2 is stuck to the disk face 1a of a hard disk 1, i.e. when a drive motor senses a specific torque or more, the heating body 7 generates heat. The heat of the heating body 7 is transferred to a slider 4 through the head arm 5 and the slider 4 is thermally expanded and slightly elastically deformed. Thereby, a fine gap is generated between the opposite face 4b of a slider 4 and the disk face 1a of the disk 1 and the adhesion between the head part 2 and the disk face 1a is eliminated. Consequently, load applied to the drive motor is instantaneously released and the generation of damages on the head part 2 and the hard disk 1 can be prevented.
