Abstract: A method of manufacturing a rubber weir main body, which manufactures a rubber weir main body intended to rise by the flow-in of a fluid and to fall by the discharge of the fluid by integrally bonding at least two main body segments divided in the circumferential direction to each other, including the steps of: forming a material removed portion with stepped portions at edges of the rubber weir main body segments previously manufactured; abutting the rubber weir main body segments on each other at the edges; laminating unvulcanized rubber sheets containing reinforcing canvasses and an unvulcanized rubber sheet on the material removed portion formed between both the rubber weir main body segments contacted with each other; and integrally vulcanizing and bonding them. With this method, a large sized rubber weir main body excellent in quality can be easily manufactured at a job site.

Abstract: A coin processing machine comprises a rotatable disk receiving deposited coins and feeding out the received coins to a coin sorting passage by a centrifugal force produced by rotation thereof. The coin sorting passage has a pair of guide members. The denomination of coins to be processed is selected, and the coins which are fed out to the coin sorting passage are processed in accordance with the denomination selected. The coin processing machine further comprises data storage of data concerning the denomination of coins to be processed. The coin data is input into the data storage. A controller reads out the coin data from the data storage in accordance with the denomination selected so as to control the coin processing.

Abstract: A coin stacker for stacking coins to be wrapped includes a pair of stacking blocks each being movable relative to the other perpendicular to a vertical plane including the center line of a coin sorting passage for passing coins of a predetermined denomination therethrough. The first stacking block includes a first inner wall section lying at an angle X to the direction in which the coin sorting passage extends and a second inner wall section lying at an angle -X to the vertical plane including the center line of the coin sorting passage. The second inner wall section is higher than the first inner wall section in the direction in which the coins are stacked. The second stacking block includes a first inner wall section and a second inner wall section.

Abstract: A coin handling machine includes a rotatable disk for receiving deposited coins and feeding out the received coins to a coin sorting passage by the centrifugal force produced by rotation thereof, the coin sorting passage having a pair of guide members for passing only coins of a denomination to be handled therethrough, a denomination selector for selecting the denomination of coins to be handled and passage width adjusting cams for adjusting the spacing between the pair of guide members of the coin sorting passage in accordance with the denomination selected by the denomination selector, the passage width adjusting cams including first and second cams having different cam profiles, a motor for rotating the first cam and the second cam and a controller for controlling the motor, the controller being adapted for selectively transmitting a driving force of the motor to the first cam or the second cam, thereby adjusting the spacing of the pair of guide members of the coin sorting passage so as to coincide with co

Abstract: A coin wrapping machine includes a coin stacking device for stacking coins. A coin support post receives the stacked coins at a post waiting position immediately below the coin stacking device and supports them on a upper surface thereof. A coin wrapping device includes a plurality of wrapping rollers for winding a wrapping film around the stacked coins and produces a wrapped coin roll. A support post moving mechanism moves the coin support post between the post waiting position, a post wrapping position where the supported coins can be wrapped by the coin wrapping device, and a post retracted position where the coin support post is retracted from between the wrapping rollers. A mode selector selects a counting mode which causes the coin wrapping machine to only count coins or a wrapping mode which causes it to count and wrap coins.

Abstract: A collapsible sheet dam comprises a bag of flexible rubber sheet fixed onto a riverbed and riverbank portions of a river, and a fluid supply and discharge port formed in the bag. In such a dam, an end portion of the bag is fixed onto the riverbed and riverbank portions at upstream side and at the same time a portion of the bag located behind the fluid supply and discharge port is fixed onto the riverbank portion and a region ranging from the riverbank portion to the riverbed portion around the fluid supply and discharge port.

Abstract: A damage-protecting flexible rubber sheet dam uses a wear-resistant, cut-resistant member having a corrosion resistance embedded in at least a part of an outer surface portion of a rubber dam body. The member mitigates and prevents damage of the outer surface portion due to wear and other various external injuries to prolong the durable life thereof.

Abstract: A flexible sheet dam is secured to the riverbed along two securing lines at upstream and downstream sides. In this dam, at least one concave and/or convex region is made in the plane of the riverbed between the two securing lines in a direction parallel to the securing lines, whereby the complete deflation of the dam can be attained without trouble.

Abstract: The width of a coin passageway in a coin handling machine is varied in accordance with the type of coins to be handled. The coin passageway comprises a pivotable rail extending from a guide member and pivotably mounted adjacent to the guide member, and a slide rail formed integrally on a slide bar. The slide bar is slidably inserted into the pivotable rail. A guide roller is formed on the end of the slide bar and engaged with a slide guide so that the sliding movement of the slide bar changes the guide roller from one position to another position and the pivotable rail is pivoted. A passageway width setting cam has a cam face which is adapted to act on the slide rail to move it translationally with the pivotable rail through the bar guide.
