摘要:
A simplified butterfly valve with low noise in which a cavitation to be generated in a narrowed flow region that is delimited by a valve disc in a valve casing is reduced thereby to control the noise, and the valve can be applied even to a flow line for a fluid containing slurry or foreign particles, and can be used for a fluid flow line through a fluid is flows at a high flow rate. In the butterfly valve with low noise, an enlarged section 35 having the enlarged sectional shape symmetrical relative to the center axis is provided in a downstream side immediately behind a valve seat so as to control or suppress the noise and cavitation which occur around the valve disc, an inner diameter Dy of the enlarged section 35 is made more than 1.3 times a inner diameter D of the piping to which the valve is mounted, and the length X1 of the enlarged section 35 is made more than 0.5 times the inner diameter D of the piping.
摘要:
A transfer vehicle includes a lateral pair of extendable and retractable arms, openable and closable hooks at front and rear ends of the arms, an arm opening and closing mechanism configured to change spacing between the arms, and a controller configured and programmed to control the arms and the arm opening and closing mechanism as well as the hooks. During article pickup, the controller pulls in an article onto the transfer vehicle by causing the arms to protrude to a position beyond the article in a state in which the hooks at a distal end in a pickup direction as viewed from the transfer vehicle are opened, thereafter closing the hooks to clamp the article, opening the arms after the clamping to provide a gap between the article and at least one of the arms, and retracting the arms in a state in which the hooks are closed.

摘要:
In a conveyor device including a branch path, the number of articles sorted to the branch path is counted accurately. The conveyor device conveys a plurality of articles and includes a main conveyor, a first branch path, a first detector, a second detector, a detection information processing section, and a charging conveyor. The first branch path branches from the main conveyor at a first branch point. The first detector and the second detector are arranged upstream and downstream, respectively, of the branch point along a conveyance direction and are arranged to detect articles on the main conveyor. The detection information processing section is configured to calculate the number of articles sorted to the first branch path based on a difference between the number of articles detected by the first detector and the number of articles detected by the second detector.
摘要:
A solar panel has a substrate (1) and a plurality of photovoltaic cells (5). The substrate (1) has a first side (1a), a second side (1b), a third side (1c) and a fourth side (1d). The plurality of photovoltaic cells (5) are provided on the substrate (1), arranged parallel to the first side (1a), and connected in series one after another. The plurality of photovoltaic cells (5) have a first trench (15a) located adjacent to the first side (1a) and parallel to the first side (1a) and a second trench (15b) located adjacent to the second side (1b) and parallel to the second side (1b), while do not have a trench located adjacent to the third side (1c) and parallel to the third side (1c) and a trench located adjacent to the fourth side (1d) and parallel to the fourth side (1d). The first trench (15a) and the second trench (15b) are formed from a surface of the plurality of photovoltaic cells (5) toward a surface of the substrate (1), and so extend to vicinities of the third side (1c) and the fourth side (1d) as not to reach an edge of the substrate (1).
