  • Patent number: 8102430
    Abstract: An interchangeable lens which can communicate with an associated camera body, the interchangeable lens including an interface logic IC; and a memory connected to the interface logic IC, and stores the data of the interchangeable lens. Fixed data of the interchangeable lens is allocated to a predetermined number of bytes of data sent from the interchangeable lens to the camera body so that terminals of the interface logic IC serve as at least one group of fixed data set-pins to which levels corresponding to the fixed data are set. In communication with the camera body for a predetermined number of bytes thereof, the interface logic IC reads the fixed data set by the group of fixed data set pins to send the read fixed data to the camera body, and sends data of the interchangeable lens which is read from the memory to the camera body.

  • Patent number: 7822339
    Abstract: An interchangeable lens which can communicate with a camera body to which the interchangeable lens is detachably attached to exchange data of the interchangeable lens, includes a logic IC serving as an interface via which the interchangeable lens communicates with the camera body; a memory which is provided independent of the logic IC, connected to the logic IC, and stores the data of the interchangeable lens; and a controller, connected to the logic IC, for controlling operations of the interchangeable lens. The logic IC selectively switches connections of terminals thereof with the memory and the controller for communication therewith upon receiving a communication signal from the camera body.

  • Patent number: 7547620
    Abstract: A method for producing a film pattern comprises a step of forming a resin film on a substrate surface; a step of incorporating into the resin film a constituent of a conductive film or a semiconductor film; a step of irradiating the resin film with an ultraviolet light; and a step of heating the resin film at a temperature not lower than a decomposition temperature of the resin to form a conductive film or a semiconductor film on the substrate, whereby the resin does not easily generate decomposition residues to improve precision and quality of the produced film pattern.

  • Patent number: 7115432
    Abstract: A fine electrode and wiring pattern with a good adhesive property is easily formed using a water-based solution easy to handle and small in environmental load, thereby improving a stability of a manufacturing process of an image-forming apparatus in the case where the water-based solution is used in the manufacturing process. A base pattern is formed using a base pattern forming material for electrode and wiring material absorption which is a water-based solution containing a water-soluble photosensitive resin component and a water-soluble metallic compound including rhodium, bismuth, ruthenium, vanadium, chromium, tin, lead, or silicon. An organic metallic compound is absorbed in the base pattern and then baking is conducted to form electrodes and wirings.
