摘要:
A variable capacity type viscous heater is provided which can carry out the capacity control reliably, and which can inhibit the endurable heat-generating efficiency of a viscous fluid from deteriorating even after a long period of service. For instance, its rear housing 6 is provided with a control chamber 9 which is communicated with a central region of a heat-generating chamber 7, and which has an internal volume capable of expanding and contracting. When a rotor 14 is kept rotated, a silicone oil held, in the heat-generating chamber 7, expands the internal volume of the control chamber 9 by the Weissenberg effect in the capacity reduction. As a result, the heating is relieved, because the silicone oil, held in the heat-generating chamber 7, is collected into the control chamber 9.

A viscous fluid type heat generator adapted for being incorporated in a heating system has front and rear housings in which a heat generating chamber containing therein a viscous fluid and a heat receiving chamber permitting a heat exchanging liquid to flow therethrough. The heat generator also has a drive shaft rotatably supported by an anti-friction bearing unit and having mounted thereon a rotor element rotating in the heat generating chamber to apply a shearing action by which the viscous fluid generates heat absorbed by the heat exchanging liquid flowing in the heat receiving chamber. The heat generator has an intermediate substance unit arranged between the heat generating chamber and the anti-friction bearing unit so as to provide a thermal isolation therebetween. The intermediate substance unit may be a shaft sealing unit, a closed vacant chamber or a combination of the shaft sealing unit and the closed vacant chamber.

A viscous heater is provided which can be manufactured readily and less expensively. For instance, it includes a rear housing 6 which is constituted by a rear plate 2 and a rear housing body 3. The rear plate 2, the rear housing body 3 and a front housing 1 are overlapped and fastened by a through bolt 5, and thereby a rear water jacket RW is formed by the rear plate 2 and the rear housing body 3.

An object of the present invention is to provide an apparatus and a method for injecting assuredly a given amount of a coloring agent to an outer surface of an electric wire and coloring it. An apparatus for coloring an electric wire 1 includes coloring nozzles 31. The coloring nozzles 31 each has a solenoid valve 51 to inject or stop injection of a coloring agent to an outer surface 3a of an electric wire by opening or closing the solenoid valve. A spike voltage is applied to a coil 40 of the solenoid valve 51 when the coloring agent is injected. The spike voltage is a voltage applied to the coil 40 which is necessary to open the solenoid valve 51. The spike voltage is applied to the coil 40 to open the solenoid valve 51 and stopped after a given period of time.

A coloring apparatus 1 includes a coloring nozzle 31 for spouting a coloring material, a signal generator 53, and a controller 19. The coloring nozzle 31 includes an electromagnetic valve 51. The signal generator 53 outputs signals for spouting the coloring material from the coloring nozzle 31 to both a CPU 62 of the controller 19 and a driving circuit 64. The CPU 62 outputs a signal for keeping the electromagnetic valve 51 open to the driving circuit 64 when a frequency of the signals from the signal generator 53 is higher than a specific frequency. When at least one of the signals from the CPU 62 and the signal generator 53 is inputted, the driving circuit 64 applies a spike voltage A and then applies a hold voltage B to a coil 40. While at least one of the signals from the CPU 62 and the signal generator 53 is inputted, the driving circuit 64 applies a spike voltage A and then continuously applies a hold voltage B to a coil 40.

A shielded electric wire 1A is composed of a plurality of covered electric wires 10 of which core wires 2 are covered by covers having different colors; a braided shield 4 attached to an outer region of the covered electric wires 10; and an insulating sheath 5 covering an outer circumference of the braided shield 4. Because the covered electric wires 10 have covers 3 having different colors, the covered electric wires 10 can be identified from each other. Further, a mark 6A for identifying the electric wire is formed on a part of the outer surface of the sheath 5. A color identifying a destination of each covered electric wire 10 is selected properly as the color of the mark 6A. Further, a combination of the colors of the covers 3 of the covered electric wires 10 and the color of the mark 6A can indicate a product type of the shielded electric wire 1A.

The present invention provides electrical cables that can be surely discriminated from one another, even when only a part of an outer surface of each cable is exposed. An electrical cable 1 has an electrically conductive core 5 and a sheathing layer 6 covering the core 5. The sheathing layer 6 has an outer surface 6a with a mono-color. On the outer surface 6a, a first mark 7 and a second mark 8 are provided. At an end 1a of the cable 1, the first mark 7 is provided on a first outer surface 1b while the second mark 8 is provided on a second outer surface 1c positioned oppositely to the first surface 1b of the sheathing layer 6. On the first outer surface 1b, a plurality of the first and second marks 7, 8 are provided to be alternately positioned in a longitudinal direction of the cable 1. The first mark 7 has a first color R while the second mark 8 has a second color G different from the first color R. Desirable variation in hue of the first and second colors R, G allows discrimination of the cables 1 from each other.

A nozzle for coloring an electric wire, by which the coloring agent can be securely spouted with a specific amount thereof per spouting toward a desired position on an outer surface of the electric wire, is provided. The nozzle 31 for coloring an electric wire spouts a liquid coloring agent with a specific amount thereof per spouting toward the outer surface of the wire so as to color the wire. The nozzle 31 includes cylindrical first and second nozzle members 37, 50 for allowing the coloring agent to flow therethrough in a direction of an arrow Q. The first and second nozzle members 37, 50 are connected coaxially to each other. The second nozzle member 50 is disposed nearer to the wire than the first nozzle member 37 is disposed. An inner diameter d of the second nozzle member 50 is smaller than an inner diameter D of the first nozzle member 37. An end surface 50a of the second nozzle member 50 near to the first nozzle member 37 protrudes toward the inside of the first nozzle member 37 from an inner surface of the first nozzle member 37. The end surface 50a is flat in a direction crossing at right angles the direction of the arrow Q.
