IPC: B41J2/135
Filed: 1981-02-12
Abstract: PURPOSE:To provide a nozzle through which ink has a favorable grain characteristic by passing pressurized air into a tube that is contracted by tension applied on both ends and heating with a wire through it, thus forming the inclined  portions at both ends of the heated section. CONSTITUTION:A metallic wire 2 with a diameter that is the same as a desired nozzle diameter is passed through a glass tube 1 which has a melting point that is lower than that of the wire 2. Tension T is applied to both ends of the glass tube 1 and at the same time its central portion is heated by a heater H. The heated portion is deformed to contract in its diametrical direction when its temperature rises over the softening point of the glass tube 1 and eventually the inside wall of the tube 1 contacts the wire 2. At this time, an inert gas that is pressurized appropriately is sent into the glass tube 1 from both ends to form the inclined sections 1a. After the tube 1 has cooled, the sections (a) and (b) that are specified by the diameter of the wire 2 are cut off with the wire 2, and then the wire 2 is removed by etching to obtain nozzles 3.

Abstract: A broadband integrated subscriber loop system is provided in accordance with the teachings of the present invention. A system is provided in which the subscribers are combined in groups (T1n1-T1n10) each of which is supplied via a single optical communication link. Over the optical waveguide (LWL) of this optical communication link, signals of the channels assigned to subscribers for various telecommunication services are transmitted on a multiplexed basis from the switching unit to an interface unit closely located to the subscribers of the group. In the interface unit the channels are separated and subscriber-assigned multiplexers (Mux 5) combine the channels assigned to a subscriber in accordance with the transmission capacity required into a subscriber time-division-multiplex signal. This signal is transmitted over a subscriber line in the form of a coaxial electric line (KL 1) to subscriber's taps, where the signals for terminals located at the top are separated via demultiplexers (Demux 3, Demux 4, Demux 5, Demux 6). Signals to be transmitted from a subscriber's terminals to the switching unit are combined in digital form (Mux 2, Mux 3, Mux 4), and a multiplexer (Mux 1) in the interface unit combines signals from all subscribers of the group into a back-channel multiplex signal which is transmitted to the switching unit over an optical communication link using the same or a second optical waveguide. In the switching unit, a demultiplexer (Demux 1) separates the received signals into the signals from the individual subscribers, and the signals of each subscriber are split up according to the subscriber's various telecommunications services. The system, including the terminals, is fully digital.
