A plastic cap with IC tag storing product information provided on the upper surface of a top plate. The top plate is formed by an annular flange and a recessed portion 37, the recessed portion, including a side wall continuous to the inner circumferential edge of the annular flange and a bottom continuous to the lower end of the side wall. The tag 10 is attached to the annular flange to cover the recessed portion. A gap between the tag and the bottom is maintained to such a degree that the transmission and reception of signals to and from the tag are not interrupted when the back surface of the bottom comes in contact with water.

A processing program preparing apparatus for a numerically controlled punch press includes a processing intention data generator for generating, on the basis of product shape data, processing intention data for specifying a processing region to be processed to manufacture a product. The processing program preparing apparatus also includes a tool data adding section for adding, to the processing intention data, data for specifying a punch and a die to be used to process the processing region.
摘要:
A punch press has a punch supporting member (22) for supporting a plurality of punches (26) and a die supporting member (24) for supporting a plurality of dies (28), wherein identification media (34, 36) representing a punch and a die identification information for identifying each tool are attached to each punch and die, respectively. The punch press comprises a punch identification medium reader (38) for reading out a punch identification information from the punch identification medium (34) attached to said punch; a die identification medium reader (40) for reading out a die identification information from the die identification medium (36) attached to said die; and a comparator (68) for comparing a punch identification information from said punch identification medium reader and a die identification information from said die identification medium reader with each other.
摘要:
According to an aspect of the disclosed invention, characteristic portions of graphic images to be used for machining in the form of profiles of a plurality of templates are first registered in advance along with machining design data corresponding to the respective profiles of the templates and including machining methods adapted to the respective profiles of the templates in the form of template machinings. Then, a specific characteristic portion is extracted out of the graph image given for a machining operation and the extracted characteristic portion is collated with each of the registered template profiles. Thereafter, the template machinings for the template profile recognized to be corresponding to the extracted characteristic portion as a result of the collation are read out from the registered data. Finally, the related machining design data is assigned to the extracted characteristic portion according to the read out template machinings to automatically prepare a machining program for a punch press.
摘要:
The invention relates to a fabric used for preparing a base member of a trim member. This fabric is prepared by heating a mixture of a vegetable stiff fiber and a thermoplastic fiber. With this heating, the thermoplastic fiber becomes soft, and thus the vegetable stiff fiber and the thermoplastic fiber are united together. Examples of the vegetable stiff fiber are hemp fiber, coconut fiber and bamboo fiber. An example of the thermoplastic fiber is a composite fiber made of polyethylene and polypropylene. The fabric is superior in strength and workability and becomes advantageously low in heating temperature for molding the fabric.

A casing and a lid which are supplied to a casing/lid supply machine are fed to a main assembly line where a light-shielding sheet is mounted on the casing and a film cover supplied from a film cover assembly line is mounted in the casing. Pressers supplied from a presser assembly line are mounted on the lid. The casing and the lid are combined with each other, completing a film case. The film case manufacturing system is capable of efficiently manufacturing highly accurate film cases and is relatively compact in structure.
