Patent JP-S62188901-A (JP)
Title: Optical position detector
Inventor: KOBAYAKAWA YOSHI
IPC: G01B11/00
Filed: 1987-02-06
Abstract: PURPOSE:To enhance an S/N ratio by providing a positive lens integrated in a photosensitive element. CONSTITUTION:A positive cylindrical lens 5 is so disposed in front of a one- dimensional array 3 that the direction of the generating line of the lens 5 is parallel to an X axis along which the array 3 is arranged. An aperture 6 which is an exit pupil is provided in the neighborhood of an imaging lens 2 and with a circular opening. The lens 5 is so disposed that the image of the aperture 6 is formed on the light receiving surface of the array 3 with a width smaller than those of the respective elements of the array 3. These elements are provided in integration with the lens 5. Thus, the luminous flux on a segment A, A', incident upon the elements of the array 3, has an incident width approximately equal to the width of the lens 5 in a (y) axis direction and a sensitivity is increased by the ratio between the width of the lens 5 and the array 3 both in the (y) axis direction. Accordingly, since the focal length of the lens 5 is smaller than the distance between the aperture 6 and the lens 5, the array 3 may be positioned in the rear focal plane of the lens 5, that is, the array 3 and the lens 5 may be integrated together.

Abstract: PURPOSE:To enable a gasket to be molded into an arbitrary shape according to the size and shape of a place to use it by covering the periphery of an elastic body with a metal net smaller than the elastic body in elasticity and capable of being molded into a predetermined shape. CONSTITUTION:An electromagnetism countermeasure gasket 10 is constituted by covering the periphery of a silicon rubber (elastic body) 20, a slender rod of recess shape in cross section, with a net body (metal net) 30 made of aluminum alloy of small elasticity. This metal net 30 can be molded into a predetermined shape because of being plastically deformed by external force.

Abstract: PURPOSE:To prevent the burning of a motor and secure the high discharge pressure by inspecting the pump discharge pressure, feeding it back to the drive mechanism of a plunger, and automatically changing the stroke of the plunger in response to the discharge pressure. CONSTITUTION:When a rotary body 10 is rotated by a motor 8, a small gear 15 provided eccentrically with the rotary body 10 is rotated inscribably with the inner gear 4 of an annular body 3, and a drive lug section 17 performs a straight line motion in the diameter direction of the inner gear 4. Immediately after the start of the pump operation, the discharge pressure of a plunger 22 is low, and a rack 6 is located at the relatively right side due to a spring 42, thereby a reciprocating motion having the maximum stroke is transmitted to the plunger 22 from the said lug section 17 via an axial direction motion extracting mechanism 21, and much fluid material is pushed out through a discharge port 41. Subsequently, when the discharge pressure of the discharge port 41 is increased, the rack 6 is moved to the left against the spring 42, and the stroke of the reciprocating motion transmitted to the plunger 22 is decreased.

Title: Dwell control method in electric injection molding machine
Inventor: KAMIGUCHI MASAO
IPC: G05D15/01
Filed: 1991-01-30
Abstract: PURPOSE:To prevent the difficulty of holding of set dwell from occurring due to the large movement of a screw, and generation of delay to set dwell when dwell pressure is changed over. CONSTITUTION:A screw is driven in the axial direction by a servomotor, and dwell is controlled. Pressure applied to a resin is detected, difference with set dwell is obtained, and movement corresponding to the difference is output to the servomotor and the servomotor is driven and the position of the servomotor is held. Consequently, dwell pressure is controlled by the position of the screw. Even when dwell pressure set is changed from a large value to a small value, the screw is not retreated by resin pressure largely, and dwell pressure is held at dwell pressure set by positioning the servomotor.

Title: Production of butt-welded steel pipe having high strength and high quality of butt-weld zone
Inventor: SAKAMOTO SHINYA
IPC: B21C37/06
Filed: 1995-02-16
Abstract: PURPOSE: To prevent the occurrence of the outside surface flaws and edge butt defects of a butt-weld zone and to obtain a butt-welded steel pipe having a high strength and high quality of butt-weld zone by installing a tension roll between forming rolls and butt-welding rolls. CONSTITUTION: A steel strip is heated in a heating furnace 2 and after the steel strip is hot formed to a tubular shape by the forming rolls 3, 4, oxygen is blown from a nozzle 7 of a welding horn 5 to the butt-welding surfaces at the edges of a tubular skelp 1 to butt-weld these surfaces just before the butt- welding rolls 6. In such a case, the tension roll 8 is installed between the forming rolls 3, 4 and the butt-welding rolls 6. The tension roll 8 is mounted on the inside surface side of the pipe in such a manner that tension is applied on the skelp edges just before butt-welding. The roll moves the skelp edges toward the outside surface side to some extent to the bases of the butt-weld zone.  As a result, the vibration is suppressed and the hot forming is stabilized even if the tension acts at the skelp edges just before the butt-welding and the occurrence of the outside surface flaws and the edge butt defects is eliminated.
