Title: Privative screw excellent in fatigue property
Inventor: SUGIMURA NOBUYUKI
IPC: F16B33/04
Filed: 1988-03-04
Abstract: PURPOSE:To prolong fatigue lifetime in a screw used in such a part where a load remarkably fluctuates as an accumulator by eliminating all contact surfaces on thread crests on such a side as to receive a tensile load so as to form all the thread contact surfaces at the same height. CONSTITUTION:Truncation of all threads of a female screw 20 at the same height eliminates contact surfaces on the thread crests, resulting in identity of all screw contact height L. This equalizes portions Fw where the threads Fs of the female screw come into contact with the threads Ms of a male screw so as to average charge loads bearing on the threads Fs and Ms irrespective of change in screwing or fastening positions, thereby resulting in almost the same bending moment generated in the bottoms of the threads Fs and Ms. Therefore, smaller peak bending moment generated in the thread bottoms in comparison with that in a conventional screw can enhance fatigue property as well as prolong fatigue lifetime.

Abstract: PURPOSE:To make operation and structure simple and to make the structure safe and inexpensive by constituting such that a leg end provided under a tail part of a main body is made to rise up by the turn of the leg to change blowing direction and that swing angle is variable by the turn of a ring centered on the leg end. CONSTITUTION:While a roller 8 is rotatably engaged with a leg 11, the leg 11 is swingably engaged with a bearing 12 formed at a tail part 5. To perform swing adjustment, the leg 11 is swung about the bearing 12 and stabilized in a position shown with dotted lines in the figure. Namely, distance between ground contact points of the roller 8 and a ring 4 against the ground 9 becomes S as shown in the figure. Since the turn of the ring 4 is constant, when the swing radius becomes smaller, blowing range is increased. Also, since the tail part 5 is raised by the leg 11, blowing angle against the floor 9 is adjusted to be small. When performing swing adjustment, the leg 11 is turned to the position shown with dotted lines as far as it is stopped with a stopper 14 formed at the tail part 5 and stabilized. Thus, the swing adjustment mechanism which is simple in operation and structure and safe can be obtained.

Title: Device for inspecting bend of lead wire
Inventor: MORIYA KAZUO
IPC: H01L21/66
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To inspect any upward or downward bend of a lead wire by irradiating the lead wire held in the specified attitude with lights with wavelengths different from each other from different directions. SOLUTION: A first illuminating means 9 emits a red light 7 to an inner lead held in the specified attitude on a tape 1 from a first direction. A second illuminating means 13 emits a blue light 11 with a second wavelength to the inner lead from a second direction different from the first direction. A color TV camera 15 picks up both red and blue lights reflecting at the same time on the inner lead. When the inner lead has any curvature, the TV camera 15 becomes sensitive to the red light and weak in the blue light, that is, the balance of light reception intensity in the TV camera 15 is changed. Therefore, the presence or absence of bend of the inner lead can be judged by observing the change in balance through the TV camera 15.
