Title: Electrofusion method and electrofusion controller used therein
Inventor: MORI MASAHIRO
IPC: B29C65/34
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To achieve the optimum fusing and to easily specify a transmission position, in fusion an electrofusion joint with a resin pipe by supplying a current to an electric heating wire embedded in the electrofusion joint, by performing the communication with an external data processor through a communication means such as PHS or the like and receiving the data related to the fusing to control fusion. SOLUTION: On the piping site, at first, the fusion of an electrofusion joint 2 with a thermoplastic resin pipe is performed by using a controller 1. At this time, the connection cable of the controller 1 is connected to the current supply terminal of the joint 2 and, when the start of work is inputted to the controller 1, the data of the bar code applied to the joint is read in a control part by a bar code reader 15 and the control of current supply is performed under the fusion condition of the joint corresponding to the bar code data and the resin of the joint is melted by the heat generated from the electric heating wire embedded in the joint 2 to fuse the joint 2 to the resin pipe. After the completion of fusion work, fusion result data is transmitted to the outside, for example, the host computer of an office by a PHS communication device 14.

Title: Label for concealing
Inventor: KANEMOTO MASAMI
IPC: G09F3/03
Filed: 1989-06-30
Abstract: PURPOSE:To allow concealing simply by sticking the label and to prevent the restoration to the original concealing state after the label is once peeled by segmenting the peeling force of a release layer to a light part and a heavy part by the irradiation quantity of ionization radiations. CONSTITUTION:The peeling force of the release layer 4 of the label 1 for concealing is segmented to the light part 6 and the heavy part 5 by the irradiation quantity of the ionization radiations. The peeling force is heavier as the irradiation quantity of the ionization radiations is larger. The release layer 4 is, therefore, formed by using a release agent of the light peeling force and is irradiated with the ionization radiation while the part to be lightly provided with the peeling force is held masked or the part to be heavily provided with the peeling force is irradiated twice. Since the release layer is provided partially in such a manner, the complete restoration to the original state is no longer possible if information is once tried to be obtd. The concealing property is thus assured.
