Abstract: An injection molding die includes a fixed half die and a movable half die which has a core surface and which is provided with ejector pins. The ejector pins are held with their extremities retracted from the core surface to form recesses corresponding to compression allowances. The ejector pins are advanced toward the cavity to compress the compression allowances after a molten resin has been injected into the injection molding die in a manner which fills the cavity and the recesses. The compression with the ejector pins renders the pressure distribution int he cavity uniform, so that a molding can be formed with a high degree of accuracy and so that the injection molding cycle time can be reduced.

Abstract: Molten resin is ejected from the gate provided in the wall of a mold, which corresponds to the face of the head insertion opening of a disk cartridge, so that the molded half of the disk cartridge has scarcely any defect in the surface thereof.

Abstract: A graphic drawing method and system are provided to display a composite graphic composed of a plurality of fundamental graphics wherein an operator designates at least two points on a display screen using a pointing device to automatically display a straight line or a curve coupling the two points. As the coordinates input mode, there are provided an ordinary input mode and an auto-adjust mode. If a coordinate input command is given in the auto-adjust mode, it is determined whether the coordinates already inputted are present within a small area spaced apart by a predetermined distance from the cursor position. If present in the small, predetermined area, the coordinates already inputted are used as the present input coordinates. If not present in the small, predetermined area, the position coordinates of the cursor are used as the input coordinates.

Abstract: An image processing apparatus that processes image data consecutively in the column and row directions has an image memory, a reading unit, a temporary memory and an operative unit. The image memory stores image data consecutively in column and row directions on a pixel unit basis. The reading unit reads from the image memory a series of pixels within one column at one row and at least one pixel adjacent to the one row in the column direction. The temporary memory sequentially stores a number of groups of pixels read from the reading unit as is necessary for image processing. The operation unit reads the values of an objective pixel and pixels necessary for a neighborhood operation of the objective pixel from the temporary memory, and subjects the values to a neighborhood operation to determine the output value of the objective pixel.

When an operator inputs a series of commands so as to effect data processing on the first window, the data processed results based on the inputted commands are displayed on the first window, whereas the inputted commands are sequentially displayed in addition to already inputted commands on the second window.

Abstract: Lower resolution video signals (10) having alternating odd fields (12) and even fields (14) are stored in an odd line memory 20A and an even line 20B, respectively. An interpolator 22 interpolates adjacent odd and even lines. A selector 24 cyclically selects odd, even, and interpolated lines in a pre-selected pattern, such as one of the patterns illustrated in FIGS. 1, 7, 8A-F, and 9A-F. By selecting even, odd, and interpolated lines, the number of lines per picture is increased to produce a higher resolution video signal (30).
