IPC: C22C16/00
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To obtain a hydrogen storage alloy capable of increasing the low temp. characteristic and high-efficiency electric discharge characteristics of a battery when used as a alkali storage battery cathode material, by using zircaloy as raw material for Zr and further controlling Sn content in an alloy in a method of manufacturing a Zr-Ni-M hydrogen storage alloy. SOLUTION: Inexpensive zircaloy, as Zr-Sn alloy, is used as raw material for Zr, and Sn is added so that Sn content in hydrogen storage alloy becomes 0.4-1.0 atomic %. When Sn is added to a Zr-Ni-M hydrogen storage alloy, Sn content in the resultant hydrogen storage alloy becomes higher than 0.3 atomic % at which the low temp. characteristic and high-efficiency electric discharge characteristic of a battery become minimal and, as a result, its low temp. characteristic and high-efficiency electric discharge characteristic can be improved. As to Sn content in the hydrogen storage alloy, when it is below 0.4 atomic % low temp. characteristic and high-efficiency electric discharge characteristic cannot be improved and, on the other hand, when it exceeds 1.0 atomic % low temp. characteristics and high-efficiency characteristics are saturated and cannot be improved any more.

Title: Extrusion machine and supply of material to extrusion machine
Inventor: KORENAGA KAZUMI
IPC: B29C48/53
Filed: 1993-03-10
Abstract: PURPOSE:To ensure stable extrusion function, even if the hardness and thickness of a material change. CONSTITUTION:A supply orifice 3 for supplying a material is provided at the base end of a cylinder 1. In addition, a screw 2 which allows the bite of a material and its transport to the tip of the cylinder 1, is provided in the cylinder 1. Further, the screw 2 is composed of a rotary shaft 6 and a spiral blade 7. At a part located in the supply orifice 3, the spiral blade 7 has the same circumferential diameter and the rotary shaft 6 has a circumferential diameter which becomes gradually narrower toward the tip. Under this constitution, if a material which allows an easy bite of itself is introduced from the supply orifice 3 in the base and side of the cylinder 1, the bite of the material is restricted as an interval between the cylinder 1 and the rotary shaft 6 is narrow. On the contrary, if a material which does not allow an easy bite of itself is introduced from the supply orifice 3 on the tip side of the cylinder 1, the bite of the material becomes deeper as the interval between the cylinder 1 and the rotary shaft 6 is wide. Consequently, both materials are always allowed to have a stable bite.
