    摘要： This invention provides a composite foil comprising an organic release layer between a metal carrier layer and an ultra-thin copper foil, and a process for producing such composite foils comprising the steps of depositing the organic release layer on the metal carrier layer and then forming an ultra-thin copper foil layer on said organic release layer by electrodeposition. The organic release layer preferably is a nitrogen-containing compound, a sulfur-containing compound, or a carboxylic acid, which provides a uniform bond strength which is adequate to prevent separation of the carrier and ultra-thin copper foil during handling and lamination, but which is significantly lower than the peel strength of a copper/substrate bond, so that the carrier can easily be removed after lamination of the composite foil to an insulating substrate. The invention also includes laminates made from such composite foils and printed wiring boards made from such laminates.

    摘要： The present invention provides a filtration method of copper electrolyte that can remove minute electrolytic by-products and dirt and may improve filtration efficiency by improving a conventional filtration method, the so-called precoating method. In a filtration method of copper electrolyte for removing electrolytic by-products and dirt which affect copper electrolysis, by passing copper electrolyte through a filter element precoated with a filtering aid, in the present invention, a precoated layer of a filtering aid is formed on a filter element in advance. Activated carbon preliminary treatment solution containing powdery activated carbon is passed through the filter element formed with the precoated layer, and is also circulated until no powdery activated carbon leaks from an outlet of the filter element, thus forming a powdery activated carbon layer on the precoated layer. Subsequently, the copper electrolyte is passed through for filtration.

    摘要： A LAN system comprises LAN controllers provided for computer systems that constitute a multi-computer system. Each LAN controller has a memory section in which a LAN address common to the multi-computer system is set in accordance with a command from a master computer of the computer systems, and a register section for holding a reception permit command (flag) from the master computer system. Only when the reception permit command is held in the register section, a transmission frame whose destination address is the LAN address held in the memory section is selectively received from a LAN and transferred to the master computer system.
