Title: Meander correcting device for band type body
Inventor: YOSHIDA KAZUO
IPC: B65H23/038
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To suppress a meander on the entering side of a meander correction roll when a meander is corrected by supporting an internal frame freely rotationally in the horizontal direction by means of an external frame arranged above the internal frame and matching the horizontal rotation center of the internal frame with the rotation center of the meander correction roll on a vertical tangent line on the outside of the meander correction roll. SOLUTION: Shaft end parts of a pair of meander correction rolls 9a, 9b, which are arranged in the front part and in the rear part individually, are journalled freely rotationally to an internal frame 4 via bearings so as to be turned with the internal frame 4. The meander correction rolls 9a, 9b forming a direction switching unit for a band type body 2 in a conveying process are turned at the same time in the horizontal direction, and their directions are changed, so that a meander of the band type body 2 wound on the rolls 9a, 9b with tension is corrected. In this process, the rotation center 4c of the internal frame 4 is positioned on a vertical tangent line on the outside of the front meander correction roll 9a and is matched with the rotation center of the front meander correction roll 9a.  In this way, a meander is suppressed on the entering side of the meander correction roll, so that the meander can be effectively and surely corrected.

Abstract: PURPOSE:To eliminate complicate relation generated between self-polarization that liquid crystal has and an orienting film and to obtain a stable device by using ferroelectric liquid crystal separated into a liquid crystal phase which is restrained by the orienting film and a liquid crystal phase which is not restrained. CONSTITUTION:Different kinds 6 and 7 of ferroelectric liquid crystal are injected into the device where a substrate 1 after uniaxial orientation processing 4 and a substrate 2 which is not processed are arranged at a constant interval in parallel. Those different kinds of liquid crystal injected into this device are so oriented that the uniaxially oriented liquid crystal layer 6 contacting the substrate surface and the other bulk liquid crystal layer 7 are separated and switched independently of each other. When an electric field is applied, a domain is easily formed in the bulk liquid crystal layer 7 as compared with the uniaxially oriented substrate surface liquid crystal layer and the layer is switched while its area is increased or decreased.

Filed: 1988-10-24
Abstract: PURPOSE:To set the power factor of a power source side completely to 1.0 and to eliminate the need for the series reactor of a capacitor by compensating reactive power through an active filter and cutting off a higher harmonic current which flows in the capacitor. CONSTITUTION:The active filter 9 is connected to the capacitor 5 in parallel and the output reactive power of the active filter 9 is controlled according to the arithmetic result of the reactive power QL of a load 2 by a control circuit 10 so as to cancel the reactive power QL of the load 2. Consequently, the reactive power of the power source side is eliminated substantially to 0 to hold the power factor of the power source side at 1.0. Further, the current Ic flowing to the capacitor 5 is detected by a current transformer 11 and its higher harmonic component is extracted by the control circuit 10 to supply the opposite-phase current of the higher harmonic component to the active filter 9, thereby controlling the higher harmonic current which flows in the capacitor 5. Consequently, the power factor is set substantially to 1.0 by using the active filter and the higher harmonic current which flows in the capacitor is suppressed to eliminate the need for the series reactor of the capacitor.
