Abstract: An endoscope system includes: an insertion portion in which an image pickup unit configured to pick up an image of an object to be examined and generate a video signal is disposed in a distal end; a video processor configured to process the video signal generated by the image pickup unit; and a signal transmission path connecting the image pickup unit and the video processor, and at least a part of the signal transmission path is a waveguide configured to allow propagation of a millimeter wave or a submillimeter wave, and signal transmission is performed by the waveguide.

Abstract: A method for manufacturing a dispersion, the method including a step of forming a reaction product by allowing at least two types of liquids to react with each other, the dispersion including a dispersion medium and particles formed from the reaction product dispersed therein. In the method described above, the at least two types of liquids are ejected from independently provided respective nozzles so that traveling directions of the liquids ejected therefrom intersect with each other at an angle of 120° or less and so that the liquids then flow in an integrated manner, whereby the reaction product is generated.

Abstract: An interchangeable lens type camera system in which an intermediate accessory is removably attached between a camera body and a lens barrel includes a first CPU provided in the camera body, a second CPU provided in the intermediate accessory, and a third CPU provided in the lens barrel. The first CPU supplies a reset signal to the second CPU in association with attachment of the intermediate accessory, and the second CPU receives the reset signal supplied from the first CPU and supplies the reset signal to the third CPU.

Abstract: In a mounting structure of an image pickup device, an optical member allowing light to pass through is bonded to one side of an electric substrate with an adhesive with the image pickup device bonded to the other side of the electric substrate. In this structure, the hardness of an adhesive for bonding the image pickup device differs from the hardness of the adhesive for the optical member. The difference in hardness between the adhesives can reduce the influence of a difference in expansion coefficient between the image pickup device and the optical member. For example, the hardness of the adhesive for bonding the optical member can be set lower than that of the adhesive for bonding the image pickup device.

Abstract: A process for producing a liquid composition containing polymeric pigment fine particles including a pigment and a polymeric compound which is soluble in an aprotic solvent and hardly soluble in a poor solvent for the pigment is constituted by a step of preparing a solution of the pigment and the polymeric compound in the aprotic solvent in the presence of alkali; and a step of mixing the solution with the poor solvent for the pigment to precipitate the polymeric pigment fine particles comprising the pigment and the polymeric compound in a dispersion state.

Abstract: A camera body including a camera CPU, a detection switch and an interchangeable lens having a lens CPU are provided. The detection switch is connected to the camera CPU and is switched in response to the start of the attachment of the interchangeable lens and is switched to a reproducing state in response to the completion of the attachment of the interchangeable lens. In this case, when the interchangeable lens is attached to the camera body, the camera CPU supplies reset signals to the lens CPU in response to the switching of the detection switch. Upon the completion of the attachment of the lens, the camera CPU cancels reset signals in response to the switching of the detection switch to the reproducing state.

Abstract: In a camera system according to the invention, a camera body and an interchangeable lens have respective identification data tables that are congruous with each other. As an appropriate data address is indicated to the interchangeable lens by the camera body, an identification data that is stored in the identification data storage section and corresponds to the indicated address is transmitted from the interchangeable lens to the camera body. The identification data judging section of the camera body compares the identification data transmitted back from the interchangeable lens and the identification data that is stored in the identification data storage section and corresponds to the address. As a result, it is determined if the dedicated accessory device is mounted on the camera body or not.
