Filed: 1982-09-17
Abstract: PURPOSE:To prevent the occurrence of abnormal wear, by a method wherein a throttle ring, attached between a rotary shaft and a side plate, is made of a material having an expansion coefficient smaller than that of the rotary shaft, and back pressure of a vane is reduced by decreasing a clearance between the throttle ring and the rotary shaft during high-speed rotation. CONSTITUTION:With rotation of a rotor 2, operating gas is introduced into a pump chamber 7 through a suction passage 9, the gas is pressurized to be discharged to the outside, oil 12 in an oil sump 11 connected to a discharge passage 10 is introduced to the base of a vane support hole 2a through a clearance (c) between a throttle ring 13, attached between a rotary shaft 1 and a side plate 6, and the rotary shaft 1, and a back pressure is applied to vanes 3, 3... to press those vanes against the inner peripheral surface of a cam ring 4. In this case, since the throttle ring 13 is made of a material having an expansion coefficient smaller than that of the rotary shaft 1, as the discharge pressure and discharge temperature increase, the clearance (c) decreases and the back pressure of the vane also reduces, resulting in prevention of abnormal wear of the vanes 3, 3... during steady operation.

IPC: G01N30/88
Filed: 1990-06-20
Abstract: PURPOSE:To study the relation among the formation, absorption and containing amount of a substance not preferable to a living body in a blood by using a predetermined amount of carbon disulfide for a dilution of serum in which ammonium sulfate is saturated and from which protein is removed. CONSTITUTION:Tyramine, histamine, tryptamine of cyclic amino acid amine produced in a body of a domestic animal or a man, and serotonin producing tryptophane which is essential amino acid and further cholesterol are analyzed from cyclic amino acid. At this time, powder of ammonium sulfate is added to the serum which is turned in the saturated state, and then separated by a centrifugal separator. As a result, a serum in which ammonium sulfate is saturated and from which protein is removed is obtained. The above five kinds of substances are extracted altogether from the serum by carbon disulfide which is not sensitive to a hydrogen flame ionization detector of gas chromatography so as to be offered as a liquid under test for chromatographic analysis. The extracted liquid is put into two kinds of columns of different fillers and, analyzed quickly in a simple manner by a hydrogen flame ionization detector. Accordingly, a minute quantity of the above five substances can be correctly analyzed with practically maximum accuracy.

IPC: B28B21/80
Filed: 1994-07-14
Abstract: PURPOSE:To manufacture a consistent quality molding easily and continuously by allowing a mold to rotate at two different speeds: low rotational speed to make a molding material stick uniformly to the inside face of a molding and a high speed to dehydrate the molding material. CONSTITUTION:A mold in which the ratio of the area of drain holes to that of a surface is 0.1 to 1.0% and the diameter of an individual hole is 0.1 to 5mm is used. Dehydrating molding is performed by making a mold rotate around the central axis. Dehydrating molding is performed in two stages, first at a low rotational speed and then at a high rotational speed. Practically a total amount of a molding material is deposited from slurry and stuck to the inside face of the mold at an even thickness during a low rotational speed. In consequence, a reinforced tubular molding of consistent quality can be obtained easily even if accurate molding conditions and a complex type of equipment are not used.
