Abstract: A control method of a fund management system including a plurality of servers that hold a distributed ledger, and executed by one of the plurality of servers, includes: receiving transaction data, the transaction data pertaining to payment processing for payment of a token from one or more applicants of crowdfunding to a management account, and storing the transaction data that is received in the distributed ledger held in each of the plurality of servers; determining, using a smart contract, whether or not a target condition of the crowdfunding is met; and outputting information indicating a result of the determining.

Abstract: A control method of an analysis device includes analyzing a binary code of each of a plurality of smart contracts stored in a first distributed ledger; obtaining, by using a result of the analyzing, items of commonization information expressing, in a common format, items of information provided by the plurality of smart contracts; and generating transaction data that includes the items of commonization information obtained and performing control of storing the transaction data generated into a second distributed ledger.

Abstract: A pair of filtering membranes are solidly bonded to a membrane-supporting plate by fusibly bonding each of the filtering membranes to the resin membrane-supporting plate. A main fusible domain is formed along peripheral edges of each of the filtering membranes. In addition, a plurality of subordinate fusible domains are intermittently formed in plural locations on one side or on both sides of the main fusible domain. By virtue of the above structure, bonding strength is secured by the main fusible domain, and yet, bonding strength is reinforced by locally provided subordinate fusible domains. A channel is formed in the membrane-supporting plate so that permeated liquid can swiftly flow through the filtering system. In addition, a plurality of projections are formed on peripheral edges of a filtration membrane cartridge facing inner surface of each gutter formed inside of each slit plate by way of causing the respective projections to slidably come into contact with the inner surface of the gutter.

Abstract: A filtration membrane module submerged with processed liquid in the processing tank. Plural plate-like, rigid membrane cartridges are vertically placed in parallel to each other as properly spaced from the adjoining membrane cartridges. The cleaning stream generating means for supplying a flow parallel to the membrane surfaces of the membrane cartridges opposes the gaps between the membrane cartridges opposite to each other. The sucking means for sucking the permeated liquid in each membrane cartridge is communicated with each passage of permeated liquid in each membrane cartridge. The membrane supporting plate for retaining the filtration membrane of the membrane cartridge is made hollow using a rigid structure member.

Abstract: A metal container comprising a sheared portion in a part of the wall thereof, a projecting portion formed adjacent to the sheared portion and outwardly projecting from the wall of the container, the projecting portion having a fractured side surface and the dimension of the projecting portion in the direction transverse to the side surface increasing in the direction outwards of the container, and a gas introducing passage extending along the sheared portion and the fractured side surface and through the wall of the container.

Abstract: A method for filling gas into a container comprises the steps of forming a severed portion through the wall of the container, deforming outwardly a wall portion of the container adjacent to the severed portion so as to form a projecting portion, whereby a gas introducing passage communicating across the wall of the container is formed, supplying pressurized gas into the container through the passage, and deforming the projecting portion inwardly to close the gas introducing passage.

Abstract: A method for manufacturing a bottom valve seat for use in a hydraulic damper is provided including the steps of: punching out a circular blank from a flat plate of a given thickness to prepare a circular blank having given dimensions; drawing the blank into a cup-shaped work having a circumferential flange portion; forming a cylindrical wall in the cup-shaped work thus provided, with the wall having a given length; and pressing the central portion of a bottom portion of the cup-shaped work downwards or internally, thereby forming an annular flat portion along the circumferential edge of the bottom portion; cutting the flange portion into given dimensions; and punching a through hole in the flange portion. In this bottom valve seat, the flange portion has a flat surface and at least one oil passage is provided in the portion of the valve seat, which is opposite to the bottom portion.
