Title: Balanced elevating/lowering mechanism
Inventor: WATT RICHARD L
IPC: A47B9/02
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To stably keep a surface at the balanced position, and to simplify the elevating/lowering operation of the balanced position of the surface. SOLUTION: A table top 12 is guided by a pair of columns 16a, 16b, and reciprocated in the perpendicular direction under the control of a balancing mechanism 18 and a control mechanism 20. When the surface 12 is elevated from the lowest position to the highest position, a connection member 22 is pivotably driven clockwise. In the opposite case, the continuous member 22 is pivotably driven counterclockwise. The urging force by a spring 26 around a first shaft 24a to be applied to the connection member 22 is exerted so as to resist the movement of the surface 12 toward the lower position. As a result, the urging force is balanced with at least the partial weight of the surface 12 and/or the independent weight to be supported by the surface 12.

Abstract: PROBLEM TO BE SOLVED: To make it possible to surely remove coating films forming photosensitive layers and under-coating layers from disposed photoreceptors to regenerate conductive substrates by immersing the photoreceptors into a swelling stripper, holding the one-side ends of the swollen photosensitive layers and under-coating layers and spirally stripping and removing these layers. SOLUTION: The photoreceptors 4 are immersed into an immersion vessel 1 in which the swelling stripper 5 is stored. After the photoreceptors 4 are immersed into the swelling stripper 5 in order to swell the photosensitive layers and under-coating layers of the photoreceptors 4 with the swelling stripper 5, the photoreceptors are taken out of the immersion vessel 1 and both ends of the photoreceptors 4 are set and held in chucks 8 disposed at the revolving shafts of holds 6. The one-side ends of the swollen films 9 are clamped in this state and while these ends are pulled to a normal direction from a tangent direction, the films are peeled and the ends of the peeled films 9 are clamped in peeling means 7.  The peeling means 7 are driven in this state and while the peeled films 9 are drawn so as not to be cut in mid-way, the peeling means 7 are gradually moved, by which the films 9 of the photosensitive layers and under-coating layers are spirally peeled from the surfaces of the conductive substrates 21.

Title: Negative pressure type doubler device
Inventor: TAKEUCHI HIROO
IPC: B60T13/52
Filed: 1980-09-10
Abstract: PURPOSE: To prevent unnecessary application of pressure to a diaphragm by putting the working chambers in communication to each other with a through hole provided in the diaphragm for penetration of tie rod when the pressure in one of the working chambers is higher than the other, and thereby balancing the two chambers in terms of pressure.  
     CONSTITUTION: A through hole 32, for penetration of a tie rod 30 connecting the front and rear walls of the shell 1, shall be open at the front surface 3C of a piston diaphragm 3, which is separable from a booster piston 2. The part surrounding the through hole 32 at the front surface 3C of piston diaphragm shall be set close to, but separable from, the rear end 46C of an expansion boot 46 enclosing the periphery of the tie rod 30. If the pressure in No.1 working chamber A is higher than that in No.2 working chamber B, part of the residual air in N0.1 working chamber A intrudes between the rear surface of the booster piston 2 and the front surface 3C of piston diaphragm to press said part surrounding the through hole 32 at the front surface 3C of piston diaphragm in the direction to separate from the rear end 46C of expansion boot 46, so that a gap is produced between these two and the chamber A and B are put in communication to each other. Thus the two chambers are balanced in terms of pressure.
