Title: Drum supporting device for taking up and unrolling apparatus
Inventor: TANICHI EIJI
IPC: B65H23/195
Filed: 1985-04-05
Abstract: PURPOSE:To enable both deflection of a drum and adverse effect to the product of a coil due to vibration caused by a winding drum to be eliminated by allowing the brake to be applied to the drum for taking up and unrolling which is installed on a revolution casing, overcoming tension of a strip and the weight of the coil. CONSTITUTION:A drum 2 for taking up and unrolling starts taking up a strip 3', a revolution casing 4 does not start revoluting before the drum takes up the specified amount of the strip. At this moment, in order to support a drum shaft 2' overcoming both tension applied to the strip 3' and gravitational force of a coil, the dynamic brake and friction brake are applied to a motor attached to the base end of a support arm 14. Thus, when the drum 2 is positioned as specified, the revolution is suspended. And after the take-up operation by the coil 3 has been completed, the strip 3' is cut off and is winded on a drum 1 allowing the take-up operation to start. This configuration enables the tip end of the drum in revolution to be supported even if it is subjected to great tension and gravitational force, and also enables deflection of the drum and adverse effect to the product of the coil due to vibration of a winding drum caused by high speed rotation, to be eliminated.

Abstract: PURPOSE:To perform uniform discharge up and down the stream of a laser gas flow by adjusting the capacitance of a capacitor connected between a discharge pin and a power line. CONSTITUTION:Electrodes 1a, 1b are installed to upper and lower sections in the atmosphere of a laser gas in oscillator.

Glow discharge is generated easily because the capacitance of the capacitors 4a, 4b is increased on the upstream side of the flow, and electricity is discharged readily because the laser gas excited upstream is made to flow down stream. Consequently, the capacitance of the capacitors 4c-4f on the downstream side is adjusted and reduced successively, the conditions of discharge are deteriorated intentionally, and the capacitors are balanced. Accordingly, electricity is discharged uniformly in the upstream and the downstream.
