An NC device includes an accumulation portion for accumulating a report-item corresponding to a report-requiring situation that occurs in a machine. A voice generator control section of the device operates a voice generator to generate a voice for announcing a report-item accumulated by an accumulation portion if a determination portion determines that a operator-in-range information has been generated or in response to a request produced by a request portion. Contrastingly, the voice generator control section does not permit the voice generator to generate the voice if the determination portion determines that the operator-in-range information has not been generated. In this manner, the voice generation is performed efficiently and the operator is reliably informed of the report item.

An automatic programming apparatus includes a process division control section, which automatically divides a machining process executed to obtain a predetermined product shape from a material shape of a workpiece. The process division control section computes a removal shape, which is a shape to be removed from the material shape when executing the machining process, based on the material shape and the product shape. The process division control section defines a reference machining boundary that intersects a reference axis defined on the product shape and divides the volume of the removal shape into two equal parts. The process division control section defines, on the removal shape, a process division boundary that intersects the reference axis based on the reference machining boundary and the profile of the product shape. The machining process is divided into a first process and a second process with the process division boundary.

The invention has for its object to provide a composite dielectric material having any desired dielectric constant selectable from a relatively wide range in a high-frequency band and a low dielectric loss tangent, and a film, substrate, electronic part or molded or otherwise formed article using the same. To accomplish this object, there is provided a composite dielectric material composition comprising a heat-resistant, low-dielectric polymeric material that is a resin composition comprising one or two or more resins having a weight-average absolute molecular weight of at least 1,000, wherein the sum of carbon atoms and hydrogen atoms in said composition is at least 99%, and some or all resin molecules have a chemical bond therebetween, and a filler. A film, substrate, electronic part or molded or otherwise formed article is obtained using this composition.

A depositing method of wall concrete, in which unset concrete is deposited in a form, includes the step of disposing a non-hygroscopic soft sheet which has a large number of hollow projections or ridges on an inner surface of the form being deformable when lateral pressure is applied thereto by the hardening of the concrete.
