  • Patent number: 8374499
    Abstract: An imaging apparatus capable of mounting an interchangeable lens thereon includes first and second terminals for communicating with the interchangeable lens, and a control unit capable of switching between a first communication mode in which a clock signal is output from the first terminal and communication is performed using the second terminal based on the clock signal and a second communication mode in which communication is performed using the second terminal without outputting the clock signal from the first terminal. The control unit is configured to output a predetermined signal from the first terminal to the interchangeable lens when a predetermined condition is not satisfied in the second communication mode.

  • Publication number: 20110287229
    Abstract: In a laminated glass, a plastic film is sandwiched between two sheets of resin intermediate film, and an infrared reflective film is formed in the plastic film by alternatively laminating resin films of different refractive indexes. The plastic film on which the infrared reflective film is formed meets any of the following conditions: (A) thermal shrinkage of 0.5 to 3% in the 90 through 150° C. temperature range, (B) modulus of elasticity in the range of 30 through 2000 MPa in a temperature range of 90 through 150° C., and (C) a rate of elongation of the plastic film of 0.3% or less when 10N tensile force per 1 m width of the plastic film is exerted in the 90 through 150° C. temperature range. This laminated glass is a curved infrared ray reflective laminated glass, with high transmissivity to visible light, high reflectivity in the infrared ray region, excellent insulating effect, and will transmit various electromagnetic waves.

  • Patent number: 7978238
    Abstract: A signal processing device includes a memory which stores correction data in advance. The signal processing device modifies the correction data stored in the memory on the basis of an image sensing signal obtained by causing an image sensing unit to perform image sensing operation in a non-exposure state. The signal processing device corrects by using the modified correction data an image sensing signal obtained by causing the image sensing unit to perform image sensing operation in an exposure state.

  • Publication number: 20110097572
    Abstract: According to the present invention, there is provided a production process of a plastic film-inserted laminated glass, the plastic film-inserted laminated glass having a laminated film in which a plastic film of 30 to 200 ?m in thickness is sandwiched between two resin intermediate films and two glass plates, the process including at least the following three steps: a step 1 for forming a laminate in which the glass plate, the resin intermediate film, the plastic film, the resin intermediate film and the glass plate are laminated together in order of mention; a step 2 for degassing the formed laminate; and a step 3 for bonding the degassed laminate by pressing and heating, wherein the steps 1 and 2 are performed under conditions that the temperature of working atmosphere and the temperatures of the plastic film and resin intermediate films fall within a range of 10 to 25° C.
