Title: Fiber reinforced composite member
Inventor: FUJISAKI MASARU
IPC: C22C49/06
Filed: 1982-07-22
Abstract: PURPOSE:To obtain a lightweight fiber reinforced composite member for a member of an internal combustion engine provided with a high modulus of rigidity and high wear resistance by mixing an Al-Si alloy having a specified Si content with SiC fibers. CONSTITUTION:This fiber reinforced composite member is made of a mixture of an Al-Si alloy having 11-25wt% Si content with the required amount of SiC fibers. The composite member is formed by mixing powder of the Al-Si alloy with about 15-30vol% staple SiC fibers and by press-molding the mixture under heating. Since the composite member contains finely and uniformly crystallized Si, it has high wear resistance and increased rigidity, so it is most suitable for use as a member of an internal combustion engine.

Title: Oil-pressure circuit for loading shovel
Inventor: YAGIYUU TAKASHI
IPC: E02F3/43
Filed: 1981-08-18
Abstract: PURPOSE:To prevent the tip-lowering of an arm to happen when the relative angle of the boom and the arm is less than a given value, by providing a switching valve between the level cylinder of an oil-pressure circuit having a function to automatically and horizontally pushing out a bucket and a boom cylinder. CONSTITUTION:A switching valve 22 is provided in pipelines 10 and 11 leading a level cylinder 9 to a boom cylinder 6 and controlled by a switching valve 22. In case where the relative angle between a boom 3 and an arm 4 is less than a given value, the switching valve 22 is in a switching position (x) or a returning position (n). Under the condition, when a direction switching valve 14B is operated, an arm cylinder 7 turns the arm 4 forwards and at the same time the level cylinder 9 operates in the extending direction of the rod. Since the switching valve 22 is interrupted then, the boom cylinder 6 does not move and thereby the tip-lowering amount of the arm 4 becomes smaller than in the conventional ones.

Abstract: PROBLEM TO BE SOLVED: To obtain a method and a reagent by which a component having shape in urine is analyzed and measured with good accuracy and quickly by mixing a urine sample, a dyeing liquid which contains a fluorescent dye, a buffer agent, and an osmotic-pressure compensating agent, and a cell-membrane injuring agent and mixed so as to be analyzed with a flow cytometer. SOLUTION: Before a urine sample which is diluted to a prescribed scale factor is measured, it is treated with a cell-membrane injuring agent so as to be dyed. It is preferable that it is treated, e.g. at 33 to 37 deg.C for 10 to 60 seconds. The urine sample is made to flow in a flow cell, it is irradiated with exciting light, and its fluorescent intensity and its scattered-light intensity are measured. A white corpuscle which is damaged by the cell-membrane inhuring agent is stained intensely, its fluorescent intensity becomes intense, and its scattered-light intensity becomes small. On the other hand, a midget epithelical cell is hardly influenced, its fluorescent intensity and its scattered-light intensity are not changed so much, and the white corpuscle can be discriminated from the midget epithelical cell.  A red corpuscle is dissolved by the cell-membrane injuring agent, but a crystal and a yeastlike fungus are not dissolved so as to be left. In addition, the urine sample which is not treated with the cell- membrane injuring agent is measured, two scattergrams are compared, and the red corpuscle is discriminated from the crystal or the yeastlike fungus.
