Title: Variable speed pulley device
Inventor: SHIRAI EIJI
IPC: F16H9/12
Filed: 1990-11-30
Abstract: PURPOSE:To make it lighter in weight and compact in size by constituting both driving and driven displacement means with each of helical spline mechanism, controlling the driving displacement means with a hydraulic mechanism, and energizing one side of driving pulley flanges to the outer side with a spring means. CONSTITUTION:Torque inherent in a driving pulley 12 is transmitted to a driven pulley 33 via a belt 55, rotating a driven shaft 31. High pressure oil is fed to a hydraulic chamber 81 and hydraulic pressure in this hydraulic chamber 81 is lowering from a maximum speed increasing ratio state when a helical follower 16 is energized to a lower end, whereby this helical follower 16 is moving upward, so an interval between both driving pulley flanges 13 and 14 is widening. At this time, a helical outer 18 is rotated by an interaction between an outer circumferential surface of the helical follower 16 and a helical spline formed in an inner circumferential surface of this helical outer 18. In this case, since a rod 63, whose one end is clamped to this helical outer 18, is shifted in the left, an interval between driving pulley flanges 33 and 34 is narrowed at the side of the driven shaft 31.

Title: Ice heat storage tank
Inventor: OMURA KATSUYA
IPC: F25C1/00
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To achieve a stable continuous operation for a long time by providing a water separation means which applies a resistance to a flow of an antifreeze extract to an antifreeze piping provided on a bottom part of a heat storage tank to separate water mixed in an antifreeze solution. SOLUTION: A multiple plate-shaped member 36 is set at an antifreeze reservoir part 26 as water separation means 35 to make an antifreeze solution 22 flow zig zag so that the flowing length of the antifreeze solution 22 is increased to retain the antifreeze solution at the reservoir part for a longer time. At the reservoir part 26, fine water particles 38 in the antifreeze solution 22 bond to other fine water particles 38 approaching them to grow. The water particles 38 thus grown ascend from the reservoir part 26 because of its increased buoyance to be absorbed into the water 21 in a heat storage tank 23. As a result, the fine water particles 38 in the antifreeze solution 22 reduces, eventually causing a decrease in the water in the antifreeze solution flowing into a refrigerating machine 32.  This can prevent the clogging of a pipe as caused by the solidification of the water 21 in a refrigerating machine 32 and achieves a stable continuous operation for a long time thereby enabling economical operation.

Title: Iron pipe and the like excellent in corrosion resisting performance covered with copolymer water dispersion
Inventor: YAMAMOTO KEN
IPC: C09D5/08
Filed: 1994-12-06
Abstract: PURPOSE: To improve the corrosion resistance of an iron pipe and the like for channel or gas pipeline to be buried. CONSTITUTION: A copolymer water dispersion in which 5-50wt.% of a conjugated diolefin having 4-6 carbon atoms is necessarily copolymerized with 3-10wt.% of at least one of ethylenic unsaturated carboxylic acids is used as a main component by use of a reactive emulsifier having a polymerizing ethylenic unsaturated group to prepare a coating material, and the coating material is applied to the inner and outer surfaces of an iron pipe covered with a Zn primer as a sealer by frame coating. Thus, even when the surface of the iron pipe makes contact with the moisture in the soil, the emulsifier is never eluted from the coating film, and fast projecting function can be kept long. Since the coating material itself is highly corrosion-resistant, and the moisture penetration to a metal layer as substrate can be arrested, corrosion by ionization of the metal is also prevented.  Further, properties such as stability, impact resistance, and white rust prevention as coating material are also remarkably more excellent than in a conventional technique.
