A flange unit for a filter unit for positioning in a water treatment device, the water treatment device including a water reservoir and a suction head. The flange unit includes a base plate having a central recess for accommodating a filling piece of the suction head, a connecting unit for detachably connecting the flange unit to an inner side of the water reservoir, a closure element for closing the recess, and a handle unit for detaching the connecting unit from the flange holding device and for carrying the filter unit.

Provided are decompression shut-off valve device having high responsiveness and a method for controlling the same. The decompression shut-off valve device 10 includes an on-off valve 30, a detection pin 50, and an interlocking member 60 which operates the on-off valve 30 by displacement of the pressure-receiving section 52, a valve chamber 31, an accommodating chamber 17, and a cylinder 40 which accommodates an enlarged diameter section 37 provided in a rod section 33 of the on-off valve 30. The rod section 33 is slidably held through a second partition wall 18, and a rod end portion 36 of the rod section 33 is connected to the detection pin 50 via the interlocking member 60. The cylinder 40 is partitioned into a small diameter low-pressure chamber 80, and a large diameter high-pressure chamber 70 in which the working fluid having a higher pressure than the low-pressure chamber 80 is accommodated.

A die casting method and apparatus are provided, thereby making it possible to produce a thin diecast product that has hitherto been considered impossible to realize, and a diecast product is also provided. A semi-solidified metallic material is formed having particles in solid phase of a particle size less than 30 m, and is thereupon injected into a die. A die casting machine has a sleeve into which a melt of metallic material is poured, and the semi-solidifying material there when it has a certain proportion of solid phase reached is injected into the die with a plunger to which pressure is applied. The melt of metallic material is poured into the sleeve so that the material occupies inside the sleeve at a proportion in vertical cross-sectional area of 30% or less. The particle size in this semi-solid material is held unvaried in a product as diecast.
