Title: Combination type oil ring
Inventor: TATEISHI YUKIO
IPC: F02F5/00
Filed: 1990-07-31
Abstract: PURPOSE:To achieve the reduction of dimension and weight and realize low fuel consumption and prevent the rise of oil under a high negative pressure by allowing the upper surface of a spacer expander to have an aslant surface higher than the outer peripheral top part, forming the undersurface flat and preventing a lower side rail from applying a force in the radial direction to a cylinder wall. CONSTITUTION:When a combination oil ring is installed on a piston 20, each outer peripheral slide surface of the upper and lower side rails 10 and 18 contacts a cylinder liner 30, and the inner peripheral edge part of the upper side rail 10 and the undersurface of the lower side rail 18 contact the upper and lower inner surfaces of an oil ring groove 21. However, a cavity is left between the inner bottom surface in the radial direction of the oil ring groove 21 and a spacer expander 11 and the upper and lower side rails 10 and 18. The inner peripheral edge part of the upper side rail 10 is nipped by the aslant surface 17 of the spacer expander 11 and the inner upper surface of the oil ring groove 21 and pressed to the outer peripheral side, and contacts the cylinder liner 30 with a prescribed surface pressure. Since the lower side rail 18 contacts a cylinder wall in the state where the force in the radial direction hardly acts, the friction between the cylinder wall is reduced drastically.

Title: Method for making ultrapure water
Inventor: MATSUMOTO SATOSHI
IPC: C02F9/00
Filed: 1986-08-29
Abstract: PURPOSE:To prevent the lowering in capacity of a semipermeable membrane, by supplying raw water after ion exchange treatment, the addition of a chlorine type sterilizing agent and pH adjustment to the semipermeable membrane composed of a cellulosic derivative. CONSTITUTION:After raw water is subjected to ion exchange treatment, a sterilizing agent such as sodium hypochlorite, hydrogen peroxide or sodium bisulfite is added to raw water in a range of 0.01-1ppm. Subsequently, raw water is adjusted to pH 4.0-6.5 and supplied to a semipermeable member formed using cellulose, cellulose acetate, cellulose butyrate or methyl cellulose as a polymer component to be treated. By this method, the lowering in the performance of the semipermeable membrane is suppressed to reduce trouble and the long-term stable operation of a process is made possible.

Title: Grinding device
Inventor: MURAKAMI EIJI
IPC: B24B37/00
Filed: 1987-08-12
Abstract: PURPOSE:To prevent the generation of vibration during grinding operation by providing holding-bodies for holding workpieces within faces spaced a specified distance apart and opposed each other with grinding medium fluid held between the faces, and driving the holding bodies to move the workpieces within the faces at a specified speed. CONSTITUTION:When rotary plates 25a and 2b on whose side surfaces plural workpieces 1 are mounted by means of workpiece-holding plates 2 are driven to rotate by an electric motor 21, flows of a grinding medium fluid 4 along the tangential direction of the rotary plates 25a, 25b are produced on the outer peripheries of the rotary plates 25a, 25b. At the portion where the rotary plates 25a and 25b are close to each other and spaced a specified distance apart, the flows of the grinding medium fluid 4 run in the opposite directions, so that these flows of the grinding medium fluid 4 collide with each other, and at this time, the grinding medium fluid 4 strikes the workpieces 1, thereby grinding the workpieces 1. In this case, since the grinding medium fluid 4 uniformly strikes each workpiece 1, each workpiece 1 is uniformly and specularly ground. This method does not utilize the fluid-bearing condition, so that the vibration due to this condition can be eliminated.

Title: Method for constructing filling steel pipe concrete column
Inventor: TANIGAKI KATSUHIKO
IPC: E04G21/02
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To restrict deformation of a steel pipe by lateral pressure when filling concrete inside the steel pipe by connecting reinforcing steel materials arranged in a symmetrical position of the steel pipe through a through bolt. SOLUTION: Reinforcing steel materials 2 are installed in a symmetrical position of a steel pipe 1 by arranging at least two sets in parallel to a central shaft of the steel pipe 1. Next, one end of a through bolt 3 is installed in one side reinforcing steel material 2 of the steel pipe 1 by a nut 5 through a bearing plate 4, and the other end is installed in the other side reinforcing steel material 2 of the steel pipe 1 by penetrating through the steel pipe 1 to thus restrict the reinforcing steel materials 2 of a symmetrical position of the steel pipe 1 by the through bolt 3.  Afterwards, when filling concrete inside the steel pipe 1, internal pressure acts as lateral pressure of the steel pipe 1, but since the reinforcing steel materials arranged in the symmetrical position are connected through the through bolt 3, deformation of the steel pipe 1 by the lateral pressure is restricted. A role of the reinforcing steel materials 2 finishes after hardening the concrete, and this is removed.
