A screw type separation device includes: a casing that has a separated liquid discharge port on one end part side and has an object discharge port on the other end part side, while the other end part side is positioned lower, in terms of vertical directions, than the one end part side; a screw shaft provided inside the casing; a first screw blade; and a second screw blade that forms a first space between one face and the first screw blade facing the one face and forms a second space between the other face and the first screw blade facing the other face.

A sludge dewatering system includes: a concentration apparatus that concentrates sludge while conveying the sludge on a top surface of a filter body; and a dewatering apparatus that subjects the sludge discharged from the concentration apparatus to pressure dewatering. The concentration apparatus includes: a filtering unit that subjects the sludge, which has been added with a first chemical agent, to gravity filtration; a chemical feeder that adds a second chemical agent to the sludge conveyed in the filtering unit; and a moving mechanism that moves the sludge, which has been added with the second chemical agent, in a direction intersecting a conveyance direction of the filter body.

A sludge condensing machine includes: a gravity filtration section conducting a gravity filtering to a sludge while conveying the sludge on an upper surface of a filtration body, and a movement mechanism, disposed at a downstream side of a sludge insertion position of the gravity filtration section, for reducing a dimension of the sludge in a width direction on the filtration body by moving the sludge in a direction intersecting a conveying direction that the sludge is conveyed by the filtration body.

To provide a balloon catheter and an apparatus and method for manufacturing the balloon catheter, whereby the degree of welding can be appropriately adjusted and the balloon catheter can be formed so as to have a desired surface profile suitable for various uses including medical use. With a shaftinserted through a catheter tubeinserted into an end portionof a balloon and also with a pressure tubefitted around a welding section where the end portionof the balloonis lapped over the catheter tube, the shaftis heated by emitting laser light from a laser radiation unitto the welding section while the shaftis rotated by a chuck, to weld the welding section.

A casing that squeezes sludge floc at one end portion, a screw shaft, a first screw blade spirally provided on an outer peripheral surface of the screw shaft, and a second screw blade provided side by side along a longitudinal direction of the screw shaft with the first screw blade with a predetermined interval from the first screw blade, are included. In the casing, a concentration zone and a separated liquid zone, which are substantially divided from each other by the first screw blade and the second screw blade, are formed. By rotation of the screw shaft, the sludge floc is squeezed in the concentration zone to be separated into sludge and separated liquid, and the separated liquid is moved rearward in the separated liquid zone to be discharged, while the sludge is discharged outside.
