A method of and a system for generating a printing ID code representing product ID information to be printed on products based on an identification information of a specific one of the products which is stored in a memory accompanying the specific product. The printing ID generation is performed by converting the identification information read in by an information reading section into an alphanumeric ID code by a notation system of base N so as to have a number of digits less than an encode ID information, converting a part of a numeric code representing a production date of the product into an alphanumeric date code by the notation system of base N and combining the alphanumeric ID code and the alphanumeric date code as a printing identification code.
摘要:
A method of and an apparatus for measuring and evaluating characteristics of material resin using an injection molding machine. Injections of resin are performed with different resin temperatures TCi and different injection velocities Vj to detect injection pressures Pr at set screw positions. Data of combinations (Pr, V, TC) of an N number of injection pressures, injection velocities and resin temperatures are obtained. An interdependency relation function PVT(t, v(x),x) expressing correlation among the injection pressure, the injection velocity and the resin temperature is obtained as PVT(t, v(x), x)=A(x)e−α(x)Tv(x)β(x) according to a least square method using the obtained data, where β(x) represents a degree of dependency on injection velocity influencing the injection pressure and “log A(x)−α(x)T” represents a degree of dependency on resin temperature influencing the injection pressure.
摘要:
There is provided a molding-condition recovery device which may easily recover the molding condition having been applied in the past, and also permits the storage of the past molding conditions in a memory having small capacity. A reduction in required memory capacity of the modification history storage file is permitted by storing only data of a component subjected to setting modification, among the components of the molding condition, in a modification history storage file. The recovery of the past molding condition is made by replacing all the set values of the presently-applied molding condition or the data in a temporary file stored with all the set values of the first molding condition with data in the modification history storage file in sequence.
摘要:
A method and apparatus for loading a magnetic tape into a cassette in which the tape winding appearance is controlled and improved. Friction sheets are disposed around the hub onto which the tape is to be wound, preferably on both sides of the tape winding area. Compressed air is blown into the cassette to press the friction sheets against the edges of the tape as the tape is wound.
摘要:
A tape reel on which a tape strip is wound comprises a cylindrical reel hub having pores distributed allover a hub wall and a center bore formed axially therein and flanges connected opposite ends of the reel hub. The interior of the center bore of the reel hub is depressurized so as thereby to attach an end portion of a tape strip to the reel hub with air sucked in through the pores.
摘要:
In a lapping apparatus including upper and lower lapping turn tables, and disc-shaped workpiece holding fittings which are held rotatably between the upper and lower lapping turn tables and defines a plurality of receiving holes in which flat workpieces are located in the receiving holes, respectively, and the flat workpieces are lapped while the workpieces are moved together with the workpiece holding fittings relative to the upper and lower lapping turn tables, the thickness of the workpiece holding fittings is set to be thinner than a finished thickness of the workpieces with a difference between the thickness of the workpiece holding fittings and the finished thickness of the workpieces being 70 .mu.m or more.
摘要:
A film forming apparatus includes a film forming chamber in which a film is formed on a substrate at a film forming position, a plurality of load lock chambers provided on the film forming chamber through gate valves respectively, a plurality of pivots provided in the film forming chamber correspondingly to the respective load lock chambers, and carrying arms supported by the pivots respectively so as to move the substrate from any one of the load lock chambers to the film forming position and contrariwise from the film forming position to any one of the load lock chambers.
