Title: Winding transfer method and device of linear material for parallel shaft continuous winder
Inventor: IKEGAMI YOSHIO
IPC: B65H67/04
Filed: 1979-09-13
Abstract: PURPOSE: To enable smooth and reliable automatic cutting and automatic binding of linear material to an empty bobbin even for large diameter linear material, by improving the cutter when transferring the winding of linear material.  
     CONSTITUTION: Under the condition where a winding bobbin 15L at fully wound side and a bobbin 15R at empty side are stopped, a rolling holder 26R at the winding bobbin 15R side is rotated to hold a linear material P between winding bobbins  15L, 15R. Then a hummer 53 reciprocating against said holder 26R is moved  toward the holding section of linear material P to press the receiving section 44 of  movable holder 37 by means of a hummer 53A. Consequently the linear material P  is completely cut through cooperative function of the holder 37 and the cutter 29R.  Thereafter empty bobbin 15R is rotated in the winding direction to start winding of  linear material P.

Filed: 1992-04-13
Abstract: PURPOSE:To decrease drive voltage, and uniform discharge in a wide range by forming the part of a discharge electrode touching discharge gas of a conductive oxide, and providing a protrusion having specified width and height on the surface thereof. CONSTITUTION:The part of a discharge electrode touching discharge gas is formed of a conductive oxide made of a specified element having perovskite type crystal structure. A protrusion of 5-200mum width and of height being 1/2 of the width or more is formed on the surface of the electrode so that ions are incident slantingly thereon. When the width of the protrusion is less than 5mum, spatters occur easily and performance lacks stability, and when the width of the protrusion exceeds 200mum, the area of the electrode for slanting incidence decreases. When the height of the protrusion is low, the slanting area of the electrode becomes small. By forming the discharge electrode of the specified conductive oxide, and providing the protrusion of a specified size on the surface thereof, it is possible to decrease discharge voltage, to simplify a drive circuit, and to increase discharge efficiency.

Abstract: PURPOSE:To improve a connection loss of an optical transmission fiber in an incident side and an emitting side by constituting so that a diameter of an incident end of a waveguide becomes larger than a core diameter of the optical transmission fiber to be connected to its part, and also a diameter of an emitting end of the waveguide is smaller than the core diameter of the optical transmission fiber to be connected. CONSTITUTION:One surface of a transparent glass substrate 10 containing an ion to be ion-exchanged, as a component is masked by a mask 12 consisting of a substance having an ion transmission preventing effect by leaving an opening 11 of a desired waveguide pattern open. Subsequently, a substance containing an ion which is contributed to an increase of a refractive index of a substrate glass is made to contact through the mask opening 11, and the ion in the glass are exchanged for the ion from the outside, by which the ion 13 from the outside is diffused into the glass. The ion which has been diffused and invaded from the outside becomes a density distribution which is the highest in the mask opening 11 part in the substrate glass and decreases toward inside the substrate and both sides. Next, the mask 12 is removed, and the second stage ion exchange treatment is executed to this substrate surface, by which an equal refractive index line becomes a semicircular outline of an upward projecting shape in the upper part of a high refractive index area.

IPC: H04B17/00
Filed: 1991-03-19
Abstract: PURPOSE:To reduce a circuit scale and to decrease erroneous setting in a test state. CONSTITUTION:A test information transmission circuit 1 of a test equipment at the test information sender side outputs alarm information of a transmission line as test information according to a prescribed rule. A detection circuit 5 of the test equipment at the test information receiver side detects the test information and informs it to a control circuit 3. Then the control circuit 3 controls a control circuit 4 to allow the switch 2 to select the test information from the circuit 1 for the transmission of it to the transmission line 6. That is, the test information is looped back and the detection circuit 5 of the test equipment sending the test information detects it and informs the control circuit 3. The control circuit 3 judges that the transmission line is normal through the notice. Since the system uses the alarm information as the test information, a detection circuit for exclusive use for the test information is not required. Moreover, erroneous setting to the test state due to erroneous detection of the test information is reduced.
