A thermal transfer sheet having a back coating layer excellent in heat-resistance is provided by using a styrene-acrylonitrile copolymer as a resin constituting the back coating layer. A thermal transfer material having an excellent heat-resistance and having a back coating layer having considerable strength is provided by incorporating at least two species of heat-resistant particles having different particle sizes in the back coating layer, since the larger species of particle imparts excellent heat-resistance to the back coating layer, the smaller species of particle enhances the total amount of the fillers, and the larger and smaller species of particles function so as to provide a synergistic effect. A thermal transfer sheet having a back coating layer which is excellent in storability is provided by incorporation an alkylphosphate multi-valent metal salt into the back coating layer, since the thus prepared back coating layer has an excellent heat-resistance, does not contaminate another menber or thermal head without wearing the thermal head, and has an excellent slip property and an excellent dye barrier property.

The tool feed rate correcting method for numerical control system and the apparatus therefor according to this invention correct the feed override values using an override correction coefficient which is calculated from the displacement information of the tool and control the tool feed rate so that machining loads can be maintained within predetermined range irrespective of the machining conditions. This invention is therefore effective in realizing machining with a high efficiency as well as in reducing the cost.

A tool retracting method and apparatus is for retracting a tool in an NC machine tool upon the detection of the occurrence of an abnormal machining condition during operation of the NC machine tool. The tool retraction direction is determined which is counter to the direction of the cutting load acting on the work at the moment of the occurrence of the machining abnormality, so that the tool can be promptly retracted without interfering with the work.

A color filter composition, a color display device, and a production method of the same with which an increase of the luminance, an increase of the contrast, an increase in the range of color reproduction, and an improvement of the function for preventing reflection of outside light can be achieved. The color filter composition has a spectral characteristic allowing specific light of the visible region to pass therethrough and is composed of fine particles of an inorganic metal oxide containing 15 percent by weight or less of particles having a particle size of 0.1 .mu.m or more based on the weight of all of the particles and contains 70 percent by weight or more of particles having a particle size of 0.01 .mu.m to 0.07 .mu.m based on the weight of all of the particles. A color filter is formed on an inner surface of a panel of a display device by screen printing or heat transfer printing by using this color filter composition.

摘要:
A magnetic coil, a magnetic contactor using the magnetic coil and a method for manufacturing the magnetic coil are disclosed wherein the magnetic coil does not need increased winding space and can be configured as having two coil terminals protruding in only one direction or as having three coil terminals. A three terminal-type magnetic contactor which uses the magnetic coil does not require an increased amount of space for the winding process, and the size of the three terminal version is reduced while still meeting insulation requirements. The magnetic coil maintains reliable electrical connection even when subjected to mechanical vibration.

A numerical control apparatus having a three-dimensional graphic display function is provided. A three-dimensional space is divided into lattice points in storing the form data of a workpiece and a tool. When the same lattice data of a plane including an X-axis and Y-axis of three-dimensional coordinates is continuous in a Z-direction, i.e., the same form continues, those lattice point data are stored using a piece of lattice data and a continuity number, and the lattice data are stored in the form of a list of links. This allows the form data of the workpiece and tool to be stored using a small memory capacity and the accuracy of display to be improved where needed without increasing the memory capacity.
