IPC: H04L12/64
Filed: 1992-05-29
Abstract: PURPOSE:To easily judge whether or not the opposite terminal equipment is equipped with an ISDN corresponding function by judging whether or not the opposite side terminal equipment is equipped with the ISDN corresponding function at the time of calling in an ISDN mode, and registering the data corresponding to the data of a calling number. CONSTITUTION:When whether or not the communicating opposite terminal equipment is equipped with the ISDN corresponding function is not clear, the calling is operated in the ISDN mode, and it is discriminated by the presence or absence of a prescribed protocol signal. Then, the discriminated data indicating whether or not the opposite terminal equipment is equipped with the ISDN corresponding function are registered in a storage part 12 corresponding to the calling number. Therefore, at the time of transmission to the terminal equipment whose equipment with the ISDN corresponding function is not clear after the data are registered, whether or not the terminal equipment is equipped with the ISDN corresponding function can be preliminarily confirmed by referring to the data registered in the storage part 12 corresponding to the calling number of the terminal equipment. As the result, the transmission can be executed in a useful communication mode by selecting the mode corresponding to the opposite communicating function.

Inventor: MIZUNO JUN
IPC: H01H69/02
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To strengthen the soldered joint of a fuse element (low melting point alloy) with a lead wire. SOLUTION: In the temperature fuse, the end part 1a of each wire rod 1 which is turned into a lead wire, is coaxially soldered so as to be joined with both the ends of a bar-like fuse element 2 made out of a low melting point alloy. The surface of the end part 1a of each wire rod 1 is plated with metals liable to be combined with a low melting point alloy 2, it is formed into a tapered shape having a narrowed point, and concurrently each end part 1a is covered with the low melting point alloy 2.  The end part 1a of each wire rod easily bites in the low melting point alloy 2 as long as the end part is made small in cross section, concurrently the contact area of each wire rod 1 with the low melting point alloy 2 is made wider because of its deep encroachment, and since almost all the contacting area is plated with metals, the combination of each end part 1a with the low melting point alloy 2 is thereby strengthened.

CONSTITUTION:When a limit switch 36 allows its contact element 38 to be biased by 0.5mm toward its main body, it is so set that a first and a second signal are produced at both the ends of a bias, which correspond to a lower limit position and an upper limit position respectively. Paper feed table drive means 28 and 30 are so constituted as to start raising the forward end section of the paper feed table 24 in response to the first signal, and as to start initiating a corresponding operation in response to the second signal. Here, if the thickness of a form is set to be 0.1mm, the paper feed device allows the paper feed table 24 to be raised up by 0.5mm at a point C every time when 5 forms are delivered. In this case, the loading edge of the uppermost form of the piled-up forms is relatively biased by a range of roughly 0.8mm with respect to the outer circumferential surface of a paper separating and feeding roller 12.
