  • Method for moistureproof coating of an electrical product
    Patent number: 4698240
    Abstract: A method for moistureproof coating of an electrical product, which comprises applying an organic solution of a polyfluoroalkyl group-containing polymer dissolved in a non-combustible low boiling point organic solvent, to a surface of an electrical product, and drying it by evaporating the low boiling point organic solvent, to form a coating layer of the polyfluoroalkyl group-containing polymer on the surface of the electrical product, wherein said polyfluoroalkyl group-containing polymer is a copolymer of a polymerizable compound having a polyfluoroalkyl group with other polymerizable compound, and the copolymer has a glass transition temperature of not higher than 60.degree. C.

  • Exposure control device for camera
    Patent number: 4131350
    Abstract: The present invention relates to an exposure control device for a camera for obtaining a proper exposure taking the differences of the films to be used into consideration, so designed that an exposure amount control circuit for controlling an exposure amount by means of a first light measuring circuit for measuring the light reflected from the film plane is provided, while a second light measuring circuit for measuring the light reflected from the shutter plane and/or the film plane is provided in such a manner that by means of the output of the second light measuring circuit the control output value of the exposure amount control circuit is compensated so as to obtain a proper exposure amount.

  • Power supply circuit for camera
    Patent number: 4126874
    Abstract: A power supply circuit for a camera wherein a detection circuit which detects the voltage of a power source is provided for supplying an electric power to the electric circuit of the camera only when the detected voltage is above a preset value.In the power supply circuit, the power supply is controlled by a detection output obtained after a voltage detecting action is performed in a stable condition by the detection circuit. The power source voltage is detected in a manner suitable for the characteristic of the battery employed. Further, the voltage detection is performed only momentarily to prevent unnecessary power consumption for voltage detection.

  • Temperature compensated exposure control apparatus for a camera
    Patent number: 4000498
    Abstract: An exposure control apparatus which can set accurate shutter speed constantly irrespective of changes in ambient temperature and which can eliminate not only an error in shutter speed caused by an expansion semiconductor element but also an error in shutter speed caused by the variation in output characteristics due to variation in temperature of a compression circuit.
