Title: V-bending method for composite type laminated steel plate
Inventor: NAKAMURA MICHIO
IPC: B21D5/01
Filed: 1989-01-24
Abstract: PURPOSE:To execute V-bending without generating a gull wing-like shape defect by pressing a composite type laminated steel plate by a punch from the upper part, and also, giving opposed pressure from a pad through a coil spring provided in the lower die. CONSTITUTION:In a space of the lower die body 8, a pad 9 and a coil spring 10 are set. On the horizontal surface of the upper part of this pad 9, a high damping composite steel plate 4 formed by placing viscoelastic resin between and laminating a steel plate is placed. Subsequently, a pump 2 is placed and pressed against the upper face of said steel plate 4 from the upper part. As a result, the coil spring 10 is compressed and the pad 9 moves to the lower part, and while giving opposed pressure from the lower part, the steel plate 4 is bent to a V-shape. In that case, a load of the steel plate 4 to the die 8 part is very small, and a gull wing phenomenon based on stress concentration is not generated. In this case, it is suitable that Rockwell hardness of the coil spring 10 is 42-45, and a spring constant is 3.0-21.0kgf/mm and 1.50-7.0kgf/mm in the case when a V-bending angle is <=90 deg., and >=90 deg., respectively.

Abstract: PURPOSE:To provide a reflection-type photocoupler of two-phase output which is small-sized and offers excellent productivity by a method wherein a light emitting part has at least one light emitting plane and a light receiving part has a plurality of light receiving planes, which are arranged on one straight line, provided with lead terminals for connection corresponding to each light receiving plane. CONSTITUTION:A light from a light emitting plane 11a passes through a window 18 for light emission. If a detecting part exists at that time, the light is reflected there and passes through a window 19 for light reception, after which the light is received by light receiving planes 12a, 12b and two-phase output can be obtained from lead terminals 16b, 16c for connection corresponding to the light receiving planes 12a, 12b respectively. By this constitution, existence and movement of an object for detection can be detected. Thus, the light emitting part 11 and the light receiving part 12 are laid on lead terminals 10a, 10b on the same plane and the light receiving part 12 has two light receiving planes 12a, 12b, thereby composing a reflection-type photo-interrupter which offers two-phase output. As a result, a size in height direction of an outer resin body can be reduced and accordingly a small-sized photo-interrupter which enables detection of existence and movement of an object for detection can be realized.
