摘要： PROBLEM TO BE SOLVED: To provide a screw of a metal injection molding machine capable of simply removing an adhesively solidified matter adhered to the inner wall face of a heating cylinder and not disturbing the stable rotary/linear sliding of the screw. SOLUTION: A screw thread front face 21' of a screw 1 to blend/inject a metal material is inclined orthogonal or forward to the axial center, a screw rear face 22 is inclined forward. In this case, an inclined angle of the screw thread front face 21' is preferably set to 0-30 deg., an inclined angle of the screw thread rear face 22 is preferably set to 5-45 deg.. By this method, the adhered/ solidified matter adhered to the inner wall face of a heating cylinder is scraped off with a scraping blade of the screw thread front face 21' in advancing/ rotating the screw 1 and is not accumulated in a large quantity, thus, the advancing/rotating motion of the screw 1 is not disturbed.

摘要： PROBLEM TO BE SOLVED: To effectively and efficiently remove chlorine contact from top water, thereby providing water which suppress the damage to piping to a low level and has good taste. SOLUTION: Water is electrolyzed in an electrolytic bath 1 to produce alkaline water and acidic water. This acidic water is deaerated in a deaerating part 11, and then is mixed with the alkaline water in a mixing tank 10. Thereby, the chlorine contact can be effectively removed without wasting the water, and the water showing alkaline can be obtained.

摘要： PROBLEM TO BE SOLVED: To adjust the degree of kneading promptly and to prevent the generation of a unmelted short pass. SOLUTION: A valve 1 for adjusting the degree of kneading has a fixed valve 10 which is divided into two, inserted from the upper and lower opening parts of the valve member insertion hole 4 of a valve block 2, and integrated and a rotary valve 20. The fixed valve 10 has a pair of channel forming holes 11 with which the column part 42 of a screw is engaged loosely, and branched channels S are formed between it and the column part 42 by the first projection parts formed in the shape of an inner gear on the downstream side in the axial direction of the holes 11. The rotary valve 20 has an outer ring part 21 which is engaged freely rotatably on the upstream side in the axial direction of the holes 11 of the fixed valve 10, and the second projection parts 22 corresponding to the first projection parts 12 are installed in the shape of the inner gear on the inside surface of the outer ring part 21. The rotary valve 20 is rotated by a rotary valve driving mechanism 30 to change the opening of the branched channels S.
