Abstract: PURPOSE: To improve the running operation of a compressor, by providing a prewhirl plate which is swingably supported in a passage extending to the impeller inlet port of a compressor and has the same shape as the side wall of an impeller inlet guide.  
     CONSTITUTION: A prewhirl plate having the same shape as the side wall 13a of an impeller inlet guide 13 is so provided in a passage extending to the impeller inlet section 15 of a compressor that the prewhirl plate can swing centering a rotary shaft 16a. In idling, the prewhirl plate 16 is displaced into a position shown by a full line in Fig. to whirl a gas flow in the impeller inlet section 15. When the rotational frequency of the compressor becomes high, the prewhirl plate 16 is moved into a position along the side wall 13a of the impeller inlet guide. The gas flow is thus whirled at an impeller inlet port in the case of necessity as in slow rotation. The prewhirl plate does not hinder the gas flow in rapid rotation. Therefore, the operation of the compressor is improved.

Abstract: PROBLEM TO BE SOLVED: To enhance the welding strength with a small current value and reduce the dispersion in a parallel type resistance welding with a lead material by forming a plating layer consisting of an Ni-based alloy partially or entirely on the outside surface. SOLUTION: A plating layer of Ni-based alloy is formed by means of electric plating so as to cover the whole surface of a base material of battery can or the part for welding a lead material thereof. The plating layer is preferably formed of an alloy of Ni; Fe, Co, Zn or Fe; and Co in prescribed ratios, which consists of a single phase in which these elements are dissolved in the crystal lattice of Ni or the combination of a plurality of phases. Since the specific resistance is larger than a single body of Ni or other elements, a stable nugget can be formed even with a small current value in a parallel type resistance welding. The alloy with Fe the content of which is set to 50 atom % or less in order to prevent rusting is particularly preferable.  The thickness of the plating layer is suitably set to 5 μm or less, or 4.5 μm or less in case of Ni-Fe alloy, and the dispersion in welding strength can be suppressed.
