摘要:
An interface unit simplifies the definition or correction of the contents of conversion from a macro instruction into micro instructions by the machine tool maker, without changing the specifications of the NC processor (3) side in numerical control equipment (NC). A receiving circuit (9, 10) receives a macro instruction delivered from the NC processor (3), and format converting circuitry (6, 8) converts the macro instruction received by the receiving circuit (9, 10) into a series of micro instructions. A transmitting circuit (11, 12) transmits the series of micro instructions obtained by the format converting circuitry (6, 8) to the NC processor (3).

In an automatic programming system for a two-saddle NC turret lathe, shape definition and machining data for defining a machining condition for each machining step are input at each machining step together with a machining code indicating the machining from machining step input apparatus, and stored in a memory. A series of machining steps to be performed by each saddle is set in steps S1 to S9 by assigning, with a machining assigning/setting apparatus, either a machining code indicating the machining condition at each of the series of the machining steps or a wait command. Then, the machining program for each saddle is automatically created by program creating apparatus in accordance with the set data and stored data.

A dwell control system of an injection molding machine is adapted to drive an injection shaft by an electric motor (20) and to control the electric motor (20) by a numerical control unit (30). At the time of a dwell operation, the numerical control unit (30) operates the electric motor (20) under the application of a torque limit to apply a predetermined pressure to a molten material in a mold (4).

For reproducing a picture with a density gradient through printing, an overlapped region is provided in a high density dot reproduction range and a low density dot reproduction range. The switch-over between the high density dot at the overlapped region is conducted where the picture density sharply changes. This reduces the unfavorable perception of quality differences in a printed picture resulting from the switch-over between the high and low density dots.

An image processing apparatus can rapidly produce a hard copy of a video image by setting parameters for processing an input image signal while a record medium is being advanced to an initial recording position. The parameters which are set are upper and lower limits for normalizing the input image signal, and are determined by performing histogram processing on the input image signal. In addition, the processing apparatus may include a plurality of combined normalization and gamma correction reference tables for processing the input image signal. One of the plurality of combined reference tables is selected on the basis of the upper and lower limits determined by the histogram processing of the input image signal. Alternatively, separate normalization and gamma correction reference tables may be used.

A method for forming a color image by using a plurality of coloring materials and controlling quantities of the coloring materials in each pixel to form different colors is disclosed. When a density to be reproduced for at least one of the coloring materials exceeds a density reproducible for that coloring material, the quantities of other coloring materials are reduced.

An image forming method comprises the steps of providing pattern elementary marks which provide an image pattern, controlling the size of the pattern elementary marks, and forming the pattern elementary marks substantially at equal intervals. The controlling step is such that use is made preferentially of the pattern elementary marks in an area wherein the variation in density gradient level relative to the variation in size of the pattern elementary marks is great. An apparatus for carrying out such method is provided.
摘要:
A positional error correction system applicable to a numerical control for controlling a machine tool along more than one control axis, such as along X and Y control axes. If the machine tool is to be positionally controlled along the X-axis, the position of the machine tool along the X-axis is corrected by a correction factor which is a function of the position of the machine tool along that axis and the position of the machine tool along the Y-axis, thus providing highly accurate position correction. The position error correction system is not restricted to merely the X and Y axes and can include control of a Z-axis. In such a case the positional correction is performed using a correction factor which is a function of the machine tool position along all three axes.

Position error correction equipment with which it is possible to perform a backlash correction or a pitch error correction with a high degree of accuracy even if the state of a numerical control machine tool, for instance, temperature, varies. Error correction data groups predetermined by measurement in respective states of the numerical control machine tool are stored in an error storage circuit (MEM) corresponding to the respective states. An error correction data selecting circuit (MPX) selects an error correction data group corresponding to a particular state of the numerical machine tool from the error correction data groups stored in the error storage circuit (MEM). A position correcting circuit (CPG) carries out a position correction by adding a correction pulse to a command pulse or feedback pulse from a position detector through utilization of the error correction data group selected by the error correction data selecting circuit (MPX).

Disclosed is a plunger rod for a syringe. The plunger rod is useful for sliding a piston within a syringe barrel. The plunger rod is characterized in that it is colored in part or in whole. The syringe is also disclosed. According to such plunger rods, even plural syringes of exactly the same external appearance and configuration can be applied with features that make it possible to readily and visually identify them by simply taking a glance at their appearances without needing a measure such as applying indication members such as labels on them. Further, the use of such plunger rods makes it possible to provide syringes of significantly enhanced visual identifiability without impairing high-level quality, functions, sanitariness and safety required for the syringes.
