摘要:
In order to detect setting defects of a self-piercing rivet in a self-piercing rivet setting machine, on a graph having X-Y coordinates representing a rivet driven stroke and a rivet driving load, a normal upper limit curve 37 defining the upper limit of a normal setting range and a normal lower limit curve 38 defining the lower limit of the normal setting range are plotted to detect a conventionally detectable setting defects. Further, a defect upper limit curve 39 and a defect lower limit curve 41 which are obtained from an additional setting defect different from the conventionally detectable setting defects are plotted between the normal upper limit curve and the normal lower limit curve, so that the additional setting defect is detected when a plotted curve 45 of actual-measurement data of a rivet under a rivet driving operation lies between the defect upper and lower limit curves.

An antenna module suitable for a reduction in size and weight of equipment and improved in manufacturability. The antenna module includes a ground element formed from a planar conductor, an antenna element formed from a planar conductor and arranged in parallel to the ground element, and a loop element formed from a tubular conductor and arranged between the ground element and the antenna element in predetermined positional relationship with both elements so as to be connected with the antenna element. The loop element has a first hollow portion passing therethrough in a given direction. The antenna module further includes an element support formed from an insulator and arranged so as to fill a space between the ground element and the antenna element and substantially fully cover an outer surface of the loop element. The element support is formed with a second hollow portion passing therethrough in the same direction as that of the first hollow portion of the loop element.

The present invention relates to an ink ribbon winding mechanism for a printer which prints with an ink ribbon. It is constructed by disposing a ribbon winding gear, which is connected with an ink ribbon winding shaft through a slipping mechanism, and a detection driving gear for detecting markers for color identification for a color ink ribbon, which is connected directly with the winding shaft, and by locating a transmission gear for transmitting the driving force of a driving source selectively to these two gears between the driving source driving the ink ribbon winding shaft and the winding gear as well as the detection driving gear. The marker for color identification are detected correctly by directly transmitting the driving force from the driving source to the ribbon winding shaft at the detetion of the markers in the color ink ribbon.

A fastener setting tool is constructed so that the mandrel of a fastener is inserted into a nose at the front end of the tool; the body of the fastener projected from the nose is inserted into the mounting hole of a base member such as a panel; under that condition, the mandrel is pulled enough to break the mandrel to enlarge the shank of the fastener body to fix the fastener by the enlarged shank portion and a flange of the fastener body. The tool also includes a broken piece collecting assembly 30 for collecting, through a path 9 within the tool, the broken pieces 37 of the mandrels, which are broken by the above pulling operation. The broken piece collecting assembly comprises a container 15 encircling the outlet port of the path and extending to elongate the path for collecting the broken pieces as discharged from the path; and a broken piece entangling prevention means disposed in the container. The broken piece entangling prevention means comprises an elongated broken piece receiver member 31 extending in the container along the axis of the path. The broken piece receiver member 31 is provided with an elongated groove 34 to receive the broken piece 37 outputted from the path in its existing posture.

The present invention relates to a label creation cassette capable of creating a label when mounted on a thermal printer used as an output unit for personal computers and wordprocessors.A cassette case 1 with a substantially rectangular surface includes substantially cylindrical cores 2a, 2b, 2c each rotatably supported therein. An image transfer tape 3 is wound around the core 2a of these three cores. Further, a thermal transfer ink ribbon 4 is wound around one of the remaining two cores or the core 2b and the other core 2c is used to wind the ink ribbon 4.

A ground conducting layer and an antenna element conducting layer are set at a predetermined position in a cavity of a molding die, and molten resin is injected into the cavity, thereby molding a resin-formed member in which said ground conducting layer and said antenna element conducting layer are integrated. As a result of this, there can provided an antenna module comprising a resin member formed by molding to be a predetermined shape, a sheet-like ground conducting layer adhered to one surface of the resin member, a sheet-like antenna element conducting layer adhered to another surface opposing to the one surface of said resin member, and a feeder for feeding electricity to the antenna element conducting layer.
摘要:
A method of and apparatus for recognizing the figure pattern of parts used in factories is disclosed in which a pattern input device, such as an ITV camera creates an electrical image of the part which is A/D converted and then stored in binary coded form. The binary coded data is then processed and compared to known stored values, using one or more characteristics of the figure pattern, to determine the identity of the viewed part.
