Title: Roll sheet supplying device and image forming device
Inventor: MOROFUJI TAKESHI
IPC: B65H26/06
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To detect a remaining amount, presence or absence and a carrier defectiveness of a roll sheet by a correlation between each detected value of a carrier roller rotational angle detection means, a roll sheet carrier amount detection means and a roll sheet rotational angle detection means. SOLUTION: When a roll sheet 2 is pulled by a paper feeding operation by a line feed(LF) 9, the roll sheet 2 rotates with a fixed shaft 1 as a center, a light shielding plate 4 fixed to the fixed shaft 1 rotates and a photosensor 3 generates an output according to rotation of the light shielding plate 4. When the diameter of the roll sheet 2 becomes large, a paper feeding integrating amount by the LF 9 is large and when the diameter becomes small, the integrating amount becomes small. A stepping motor 10 rotating the LF 9 via an LF shaft 11 is controlled by a controller 5 and the displacement is exactly recognized by a calculation on the inside of the controller 5 if step-out of a motor and sliding of the sheet 2 and the LF 9 are not generated. Therefore, a remaining amount of the roll sheet 2 can be calculated from a minimum diameter and thickness of the roll sheet 2.

Title: Manufacture of misch metal-nickel ternary alloy for occluding hydrogen and its manufacture
Inventor: OOSUMI YASUAKI
IPC: F17C11/00
Filed: 1980-10-02
Abstract: PURPOSE:To manufacture the titled alloy having characteristics which bring on less change in the hydrogenation pressure to the composition of hydride in the plateau range by heat treating a misch metal-nickel ternary alloy at a specified temp. CONSTITUTION:An alloy represented by formula MmNi5-xAx (where Mn is misch metal; A is Al, Cr, Si or Co; when A is Al, Cr or Si, x is 0.01-2; and when A is Co, x is 0.1-4.9) is heat treated at 500-1,000 deg.C for 0.25-6hr under reduced pressure or in an inert gaseous atmosphere, and the treated alloy is cooled. Thus, unstable lattice gaps produced in the manufacture of the alloy disappear, so a singlephase alloy is obtd. Since this alloy reacts with hydrogen at a higher reaction rate in a hydrogen occluding and releasing process, the time required to complete the reaction is shortened, and the occlusion of hydrogen is finished in a shorter time. The alloy itself is not deteriorated by repeating the occlusion and release of hydrogen, and the alloy can be used over a long term.
