Abstract: A dome camera includes an inner cover covering a camera lens and a semi-spherical outer cover covering the inner cover, the camera lens being rotatable in a tilt direction and in a pan direction. The inner cover includes a partially spherical portion having an inclined support plane on which the outer cover is supported such that a radial line perpendicular to the inclined support plane is inclined at a predetermined inclination angle with respect to a line passing through a center of the partially spherical portion and extends perpendicular to the installation face. A semi-spherical portion has a window, the semi-spherical portion is covered by the outer cover supported on the inclined support plane, and the outer cover rotatable in the pan direction, so as to orient the window in accordance with the orientation of the camera lens.

Abstract: The dome camera is a fixed-type dome camera having a camera lens, a direction of which is manually set. An inner cover is supported to a parallel support portion of a base. A dome cover is supported on an inclined step portion of the inner cover with the dome cover inclined by an inclination angle ?1. A pan direction of the camera lens has a predefined target direction to be set, and the inner cover is rotatable in the pan direction relative to the base, so as to be directed toward the target direction. An optical axis X of the camera lens passes through a spherical center of the dome cover, and an inclination limit angle of the dome cover is ?2.

Abstract: A camera device includes: an image pickup element; a birefringent plate fixed to a front surface of the image pickup element; and an optical glass member arranged on an optical path of the image pickup element on a front side of the birefringent plate. The optical glass member has a plurality of optical characteristic areas with different optical characteristics from each other. The optical characteristic areas are switched such that one of the plurality of optical characteristic areas is arranged on the optical path by moving the optical glass member in a direction intersecting with the optical path. The plurality of optical characteristic areas include an infrared cut filter area and a blank glass area. The infrared cut filter area is formed by depositing an infrared cut material with infrared cut characteristics on a surface of the optical glass member.

Abstract: The object of the present invention is reuse of the filtrate of a paint mist-cleaning water mixture as cleaning water without reduction in concentration efficiency. According to the present invention, a waste paint-cleaning water mixture 2 available on trapping a water-based paint mist in cleaning water 1 is concentrated to recover the paint and the aqueous phase is recycled as cleaning water. In this system, the cleaning water prepared by reusing the aqueous phase is adjusted to an acid value of not greater than 10 and a pH value of 7.0 to 9.0. Controlling the amount of low molecular acid components in the aqueous phase in this manner prevents an abnormal viscosity increase in the filtration-concentration of the waste paint-cleaning water mixture.

Abstract: A water-based paint composition suitable for re-use with the retention of the intended coating property when recovered from a flushing water utilized to collect the paint composition remain undeposited on an article in a painting process. The water-based paint composition comprises a water-soluble resin selected from the group consisting of alkyd resin and acrylic resin to have an acid value of 25 to 100, a hydroxyl value of 35 to 200, and a solubility parameter (SP) of 10.0 to 11.0. The paint composition also incorporate a curing agent having a solubility parameter (SP) which is higher than that of the water-soluble resin by 0.5 to 3.0.
