Title: Self tapping screw
Inventor: SAKAMOTO HIROYUKI
IPC: F16B25/08
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a self tapping screw having relatively low screwing torque to make generation as small as possible of a crack at screwing time to a workpiece of resin or the like. SOLUTION: Since this self tapping screw is constituted such that an apex angle α1 is 20 deg.C or less to be continued to a first flank surface 11, also an opposed flank angle α2 formed by a second flank surface 12 in a base part side of a thread ridge 10 is set to an angle looser than the apex angle α1, the thread ridge 10 is constituted by a compound angle comprising the apex angle α1 and the opposed flank angle α2, and a bottom 13 between the thread ridge 10 and its adjacent thread ridge 10 is formed in tapered shape having a thick head part side and a thin tip end side, the self tapping screw, even when it is used in a workpiece of glass fiber reinforced resin or the like, can screw a leg part surely into the workpiece with relatively low screwing torque, to eliminate generation of a crack in the workpiece.  Further, even if using an alloy material-made resin of easy recycle as the workpiece from corresponding to a social problem of recyclability, incineration waste, etc., generation of a whitening phenomenon is prevented.

Title: Vibrationproofing device
Inventor: FURANSOWA BUAZE
IPC: G03B5/00
Filed: 1988-10-19
Abstract: PURPOSE:To prevent a correcting optical means for preventing an image blur from being displaced to the position beyond a displaceable zone and from generating the larger image blur by lowering the driving speed of a driving means for the correcting optical means in response with the movement of the correcting optical means near to the displaceable threshold. CONSTITUTION:The direction and quantity of the blur are detected when the blur arises in a camera. The correcting optical system 2 is then displaced by a cam 4 in the direction where the image blur is negated, i.e., in the direction opposite to the direction of the image blur of the image plane within the plane perpendicular to the photographing optical axis according to the direction and quantity of the blur. The driving speed of a motor 5 is lowered as a moving part 1 moves near to the threshold of the displaceable zone to prevent movement of the cam 4 to the position beyond the threshold position at this time. The correcting optical means is thereby prevented from displacing to the position beyond the displaceable zone and from generating the larger image blur.
