  • Patent number: 11302994
    Abstract: In producing a mono-cell, the mono-cell is formed from separator, positive electrode, separator and negative electrode which are joined to each other. Negative electrode is joined, one by one, to one surface of strip of continuously conveyed separator. Positive electrode having different size from negative electrode is joined, one by one, to the other surface of separator. Strip of continuously conveyed second separator is joined to one of negative and positive electrodes. Position of negative electrode joined to separator is detected by negative electrode joining position detection cameras, and joining position of positive electrode is corrected by positive electrode alignment mechanism with this detected position of negative electrode being a reference during conveyance of positive electrode along positive electrode conveyance direction.

  • Patent number: 10656892
    Abstract: When virtual printers are collectively registered with a plurality of print services through one operation, a virtual printer may be registered also with print services not utilized. In the present invention, by acquiring information regarding print services, provided by a plurality of print services, and information regarding virtual printers registered with the print services, it is determined, on a basis of the information regarding the virtual printers and a printer ID of the local printer, whether or not the local printer has been registered as a virtual printer with the print services. Information regarding the print service with which the local printer is determined not to have been registered is displayed, and when instructed by a user to register the local printer with the displayed print service as a virtual printer, the local printer is registered as the virtual printer with the instructed print service.

  • Publication number: 20200136190
    Abstract: A mono-cell is formed of a separator, a positive electrode, a separator and a negative electrode bonded to one another. Each separator includes a ceramic layer facing the positive electrode. On a lower surface and an upper surface of the positive electrode, an adhesive is applied at points lined up on a straight line along a width direction orthogonal to a conveyance direction. When an application length is defined as the product of the number of application points of the adhesive lined up in the width direction and the application diameter of each adhesive, the number of application points and the application diameter are set such that a value obtained by dividing, by the application length, a force applied to each ceramic layer based on acceleration and the weight of the separator during suction and conveyance becomes smaller than the necessary peeling strength per unit length of the ceramic layer.

  • Patent number: 9946498
    Abstract: An information processing apparatus to execute an agent module for controlling communication between a print server and the information processing apparatus, which includes a conversion unit, a transmission unit, and a notification unit. The conversion unit converts a request received from a spooler system of the information processing apparatus. The transmission unit transmits the converted request to a destination corresponding to the print server. Where a first authentication error indicating that proxy authentication is required is received after the request is transmitted, the spooler system is notified of a second authentication error indicating that a different authentication is required. Where a request including authentication information usable for proxy authentication is received as a response to the second authentication error, the conversion unit adds the authentication information to the request as information for proxy authentication.
