Abstract: An easily recyclable container obtained by subjecting a sheet L which is a laminate of a plurality of layers, to vacuum forming and/or pressure forming, in which container the sheet L has such two adjacent layers as to give the minimum peeling strength and can be manually separated into two portions at the interface of the two adjacent layers, and when the portion of the sheet L present from the interface of said two adjacent layers to the inner surface of the container is named as film portion F and the portion of the sheet L present from said interface to the outer surface of the container is named as sheet portion S, the peeling strength required for peeling of the film portion F from the sheet portion S is set at 2 to 45 g/15 mm (width) by allowing said two adjacent layers giving the minimum peeling strength to be constituted by respective particular resins or resin compositions.

Abstract: An electrically-operated curtain drawing/undrawing mechanism comprises a reduction gear connected on the output shaft side of a motor and a driving pulley connected to the reduction gear through an electromagnetic clutch, and further includes an operating switch for sending an operating signal to an electromagnetic clutch circuit in which the electromagnetic clutch is incorporated, and a control logic circuit for sending an operating signal for the motor to the electromagnetic clutch circuit, the electromagnetic clutch circuit being provided for sending the operating signal for sending the operating signal for the electromagnetic clutch to the control logic circuit. Ball bearings are incorporated in the respective bearing portions of a driven pulley and leading curtain runner's wheels.

Abstract: A hand-weaving device which contains a body having a large number of small holes arranged regularly, for weaving pins are inserted into the holes to stand upright, a longitudinal thread is turned around to the pins for warping, and a tranverse thread is woven between the warpings by use of a needle, a shuttle board and the like.

Abstract: A curtain drawer arrangement comprises a curtain rail and a plurality of curtain runners and a motor-driven mechanism depending therefrom. The curtain rail is provided with a lead plate having a conductive lead line of a greater width and a conductive lead line of a smaller width. Brushes are disposed in the motor-driven mechanism and engage the lead line of a greater width. Another brush is disposed in the mechanism and engages the lead line of a smaller width. A collector is connected to a reversible motor. The motor-driven mechanism is also provided with tired wheels which rotate in response to the actuation of the reversible motor. A control panel for drawing or opening the curtain is connected with both the lead lines.
