摘要： An injection control method for controlling the weight of a plasticized synthetic resin injected from the cylinder of the injection molder to fill the cavity of a mold. An object of the invention is to offer the method for keeping the quality of the products constant even if there is an influence by outside disturbances or there is a change in the given conditions, such as the molten resin pressure. Another object is to offer a method wherein a study and an analysis from the beginning is not required, different from the adaptive control, in case of the change of the mold. The travel distance S.sub.D of the screw to the position for injecting the plasticized synthetic resin by the amount corresponding to the weight value G of a product is calculated by a specified calculation formula and preset. And the injection of the plasticized synthetic resin into the mold cavity is stopped when the screw has moved for the preset travel distances S.sub.D from the stop position immediately before injection.

摘要： The invention relates to a method of controlling the injection speed selecting points of an injection molder, or more specifically to a method of controlling the injection speed selecting points of an injection molder injecting plasticized synthetic resin from the cylinder into a mold cavity at speed varied in multiple steps in each injection process. The objective is to control the injection molder so as to mold a product with constant surface quality in each injection process for continuous molding production. For this purpose, appropriate injection speed selecting points are determined for each injection process so as to ensure that a constant weight of plasticized synthetic resin is injected at each selected speed, and the injection speed selecting points of the injection molder is controlled accordingly.

摘要： A method for controlling an injection molding machine involving the steps of: detecting, by a screw position detector, a position of a screw of the injection molding machine immediately before the start of injection, to produce a detecting signal; comparing the detecting value with a predetermined value for a plasticizing/measurement position set in a metering position setter, to calculate any deviation therebetween; and adding/substracting the deviation to or from predetermined values representative of switching-over positions set in switching-over position setters, thereby keeping constant an actual screw stroke from the plasticizing/measurement position to the switching-over position for every shot of the injection molding machine.

摘要： An optical system is disclosed for an endoscope having a generally tubular distal end in which an objective lens assembly and an image sensor in the form of a solid-state video camera are internally housed so that an image formed by the lens assembly is focussed upon the input or pickup surface of the video camera. The video camera is disposed along or in proximity to the center axis of the distal end of the endoscope and in some instances is oblique with respect to the center axis. The video camera may be positioned in this way due to the provision of a reflecting surface which is angularly disposed in opposing relationship with an input surface of the video camera, and deflection means disposed in front of the lens assembly and within the objective lens assembly, or between the lens assembly and the reflecting surface so that an image formed by the lens assembly can be focussed on the input surface of the video camera.
