Title: Multilayer plastic structure, and production unit and manufacture thereof
Inventor: TERENSU AREKUSANDAA BENJI
IPC: B32B27/08
Filed: 1984-07-13
Abstract: A multilayer plastics sheet destined to be formed into foodstuff containers by thermoforming has a barrier layer for low oxygen permeability, and incorporates reclaim material for providing desired mechanical properties to the sheet. The reclaim material represents 40-60% of the sheet by volume, and in order to incorporate these high reclaim levels without concomitant organoleptic problems the reclaim material is formed as a single layer adjacent what is to be the outside surface of the container. The sheet is accordingly highly asymmetric, but any substantial polymer melt instability during coextrusion tending to cause layer thickness variation and lack of visual appeal of the sheet is prevented by forming the sheet as two substantially symmetrical components which are individually and separately coextruded, and subsequently extrusion laminated together. Of the components one includes, and is symmetrical in relation to, the barrier layer, and the other likewise incorporates the reclaim layer.

Filed: 1989-06-06
Abstract: PURPOSE:To make the motion of a component of a robot closer to that of a human body by a method wherein a shape memory alloy wire, which is constricted by heating or stop of heating, is constricted and restored to the original length by applying Joule heating. CONSTITUTION:A piano wire spring 20 as a driving member is provided inside a finger 12 across the whole length of a component, and a shape memory alloy wire 18 is laid across the whole length of the finger 12. One end of the shape memory alloy wire 18 is connected and fixed to the end 20a of the piano wire spring 20 at the finger tip, and the other end is wound around ceramic pulleys 22a and 22b which are located on the palm side of the surface skin 10. When a certain voltage is applied between the tail end 20b of the piano wire spring 20 and the end 18b of the shape memory alloy wire 18, the shape memory alloy wire 18 is heated by Joule heat and constricted at a definite contraction rate, so that the finger 12 bends. The angle of bend is adjustable depending upon the length of the shape memory alloy wire 18 and the diameter of a ceramic pulley 16. When the voltage is released, the shape memory alloy wire 18 stretches to the original length, and the finger 12 is restored to stretching state by the driving force of the spring 20.

Title: Four-directional switch device
Inventor: KITAWAKI HIROYASU
IPC: H01H25/04
Filed: 1994-06-27
Abstract: PURPOSE:To reduce the number of components and construct the device in a small size. CONSTITUTION:A contact piece 400 is furnished on a slider 4, and the line segment tying the two movable contacts 403, 404 of the contact piece 400 is inclined with reference to the four moving directions of the contact piece 400. When an operating piece 3 is rotated in four directions, the contact piece 400 moves in four directions on a circuit board 5 while the slider 4 is interposed, and thereby the first, second, third, and fourth circuits are formed. Accordingly four circuits can be formed from one contact piece 400 to result in use of a smaller number of components. Because the line segment as mentioned above is inclined with reference to the four moving directions of the contact piece 400, the sliding distance of the slider 4 can be lessened and the switch device be constructed small. Further because the contact piece 400 can be made long, it is possible to lessen the spring stress of the contact piece.
