Title: Channel duplexing system
Inventor: SHINDOU YASUSHI
IPC: H04L12/42
Filed: 1983-04-13
Abstract: PURPOSE:To obtain a channel duplexing system which requires a loop-back connection even when a transmission line is abnormal by connecting plural nodes in a loop by two-way transmission lines, and transmitting and receiving the same data through two paths. CONSTITUTION:The nodes 21-25 are connected in a loop through the two-way transmission lines 26-30. A node 31 receives data from transmission lines 33 and 34 by data receivers 36 and 37 and sends them out to transmission lines 35 and 32 through switches 382 and 381. Further, the switches 382 and 381 are connected to dotted-line sides in transmission to transmit transmit data of a data transmitter 39 to transmission lines 35 and 32 simultaneously. Consequently, even if one two-way transmission line becomes abnormal, only one path among the nodes becomes abnormal and the other path is still normal, so communication among the nodes is carried on without employing any loop-back connection.

Abstract: PURPOSE:To prevent the abnormalities caused by the unstable behaviour of an ink feed passage such as wear, failure, etc. checking the curvature of the feed passage, by providing a control means for controlling the direction of the ink feed passage by applying tension to the flexible ink feed passage. CONSTITUTION:The ink feed passage 15 fixed between the two points of a sub-ink-tank 14 and a main ink tank is made to go over the pulley 17 fixed, in a free rotation manner, to the spring 19, as a tension generating means, of which one end is fixed to a casing 20. The pulley 17 is pulled by the spring 19 and the feed passage 15 is always loaded by tension. Then, the direction of the feed passage 15 is kept in the tensile direction to be controlled. The spring 19 expands and contracts following the motion of the carriage 13 and the pulley 17 moves smoothly rotating on the feed passage 15 according to its expansion and contraction. Therefore, the connecting direction of the feed passage 15 is always controlled even when the carriage 13 moves. Thereby, there is not wear between the casing of an apparatus or the like and the ink feed passage and the feed passage does not swing also. Then, the stable behaviour of the feed passage position can be achieved.

Title: Liquid sensor
Inventor: YAMAZAKI TETSUYA
IPC: G01V8/16
Filed: 1984-03-31
Abstract: PURPOSE:To sense liquid over a wide range by covering even a substrate surface other than the exposed part of an optical waveguide with a coating layer. CONSTITUTION:When liquid with a larger refractive index sticks on a coating layer 13 and infiltrates into it, light capable of traveling in the optical waveguide 12 is determined not by the critical angle theta1 of the interface between the optical waveguide 12 and substrate 11, but the critical angle theta2 of the interface between the waveguide 12 and layer 13. The angle theta1, however, is larger than the angle theta2, so the rate of total reflection decreases and the quantity of propagating light also decreases, so that a liquid leak is sensed. Further, the layer 13 covers not only the exposed part 12D, but also the surface 11A connecting with the exposed part 12D. Therefore, oil sticking on the layer 13 except at the exposed part 12D infiltrates in the layer up to the exposed part 12D. Further, the waveguide 12 is branched into two branch lines 12C, so the liquid leak is sensed in a plane shape over a wide range much wider than the diameter of the waveguide 12.
