摘要:
A pneumatic tire comprising a tread which contacts a road surface and comprises a rubber composition which contains a rubber component composed of 70% by weight or more of a copolymer of a conjugated diene and a vinyl aromatic hydrocarbon and a remaining amount of another synthetic rubber and/or natural rubber, at least one reinforcing filler selected from a group consisting of carbon black and silica, and at least one type of vulcanization accelerator, such as bis(4-methylbenzothiazolyl-2)-disulfide, bis(5-methylbenzothiazolyl-2)-disulfide, mercapto-4-methylbenzothiazole, and mercapto-5-methylbenzothiazole, an amount of the reinforcing filler being 45 to 120 parts by weight and an amount of the vulcanization accelerator being 0.5 to 5.0 parts by weight per 100 parts by weight of the rubber component. Decrease in chipping resistance during tire use is suppressed, and both abrasion resistance and controllability on wet roads after use of the tire are improved.

The present invention provide for a cutting tool member that has been coated with a hard coating. The hard coating has multiple layers including: a) a layer made of a titanium compound that has a cubic lattice structure, b) an Al.sub.2 O.sub.3 layer, and c) an intervening layer that includes a Ti.sub.2 O.sub.3 compound with a corundum-type lattice structure. The hard coating layer provides the cutting tool member with good strength and increases its operational lifetime.

A CAD apparatus includes an input device, a central processing unit, and a display device. In the CAD apparatus, the central processing unit uses an intersection/contact point calculation function to determine diagrammatical elements of points, lines, and circles which are additional elements by using the points, the lines, and the circles as fundamental elements in plotting and inputting necessary parameters to the input device, so that a macro-diagram is formed on a screen of the display device, with a diagram-forming process being performed by accumulation of constraint conditions.
摘要:
In order to simultaneously observe a transparent object from two directions, first and second beam paths containing first and second images from two directions are separated using a prism to reflect the second beam path yet pass the first beam path. The length of the second beam path is caused to be different from that of the first beam path. Then the first and second beam paths are combined so that the first and second images may be viewed simultaneously. The different beam path lengths result in the first and second images being formed at the same position. As a result, the images carried by the first and second beam paths, both passing through a single objective lens, may be viewed simultaneously at a single location.

Or, the plastic sheet or sheets contain at least one color pigment, 5 to 40 parts by weight of an inorganic pigment and 0.005 to 0.5 parts by weight of carbon black per 100 parts by weight of a resin.
摘要:
In a brake controlling device (20), a separating valve (60) is provided in a main flow path (45) for interconnecting a first liquid pressure circuit and a second liquid pressure circuit. When an abnormality detecting section detects an abnormality relating to brake fluid pressure, a controlling section sets the separating valve (60) to a closed state. A leakage suppressing section performs leakage suppressing processing for suppressing entry of a brake fluid, which is in the first liquid pressure circuit, into the second liquid pressure circuit after the separating valve (60) is set to the closed state. A leakage suppressing section sets a master cut valve (64) to a closed state to perform the leakage suppressing processing.

A hydraulic brake unit is provided. The hydraulic brake unit includes a manual hydraulic pressure supply unit that pressurizes a hydraulic medium supplied from a reservoir and generates a hydraulic pressure corresponding to a brake operation amount; first and second hydraulic systems in which the manual hydraulic pressure supply unit communicates with first and second wheel cylinders; a separation valve provided between the first hydraulic system and the second hydraulic system; and a brake ECU having a separation valve control unit and a hydraulic medium amount detection unit. The separation valve control unit executes control to close the separation valve when the hydraulic medium amount detection unit detects that the hydraulic medium stored in the reservoir has decreased below a predetermined amount.

摘要:
In a brake control device and a brake control method, when a shift to a brake mode for backup involving separation of a supply path of working fluid is performed at the time of detection of an abnormality during braking, a differential pressure acting between an outlet opening and an inlet opening of an open-close valve which is provided between a hydraulic pressure source that is used during the backup brake mode and wheel cylinders and which needs to be opened during the backup brake mode is lessened prior to the separation of the supply path of working fluid so that the open-close valve is opened in accordance with a valve-opening command. Therefore, at the time of switch of the control mode, the confinement of wheel cylinder pressure is avoided.
