  • Patent number: 7198656
    Abstract: There is disclosed a vacuum cleaner including a dust separation section which separates air and dust flowing toward an intake port of a motor blower through a connection port of a cleaner main body. The dust separation section includes an air path forming member which performs a separation function. The forming member includes an introductory port, a derivative port, and an opening disposed between these. In the separation function, while dust-containing air flows toward the derivative port from the introductory port, a part of the air is sucked by the motor blower through the opening. Accordingly, the air is separated from the dust which goes straight in the air path forming member with inertia.

  • Publication number: 20060133061
    Abstract: An ornament plate of a ring-shape made of a metal with a high heat radiation effect, for instance, aluminum, is attached to an end surface on an object side of a lens barrel such that the ornament plate covers the whole front part of the lens barrel. Four kinds of LEDs of high luminance type constructing an LED light source are attached to the lens barrel through the ornament plate used as a substrate. A light diffusion cover made of a transparent resin is attached to the front of the ornament plate for covering the LEDs. When using the flash, a high voltage current is applied to the LEDs to emit flash light. Each LED generates heat. However, the heat is radiated through the ornament plate.

  • Publication number: 20040066461
    Abstract: An electronic camera that makes it possible to determine an image-capturing angle of view by displaying a live image on an LCD before a still image-recording even if the object is dark. When the live image is displayed, a cycle for outputting image signals in one field from a CCD can be changed to another cycle; e.g., from a normal video rate of {fraction (1/60)} second to {fraction (1/30)} second. Therefore, the exposure time of the CCD can be longer than the normal exposure, and thus, the live image with a suitable brightness can be displayed on the LCD even if the object is dark. The electronic camera is provided with an electronic flash that can be intermittently activated by switching on a switch or automatically if the object is dark before the image recording.

    Abstract: A fastening device is provided with a radially contractible and expandable wedge-shaped collet (5) having a V-shaped section and a tapered outer circumference (5c), and supported on the opposite support surfaces (2c, 63b) of a fastening nut (2) and a fastening ring (63). A taper ring (60) is fitted on the collet (5). When fastening an object (T) to a spindle (1), an operating ring (67) is turned in a fastening direction to move the taper ring (60) axially so as to compress the collet (5) and, at the same time, the fastening nut (2) is screwed on an externally threaded part (1a) of the spindle (1). When removing the object (T) from the spindle (1), the operating ring (67), which can be easily turned, in an unfastening direction to remove a compressive force acting on the collet (5) by axially moving the taper ring (60) so that an axial fastening force is removed from the object (T). Then, the fastening nut (2) can be easily turned to remove the object (T) from the spindle (1).

  • Patent number: 6115557
    Abstract: A front chassis and a rear chassis of an electronic camera are made of light transmissible resin. The electronic camera has a plurality of light-shielding elements to prevent unnecessary light (external ambient light and internally emitted light, for example) from entering optical systems such as taking lenses and light guides which guide light to an electronic flash control sensor. Further, the shielding elements prevent unnecessary light from entering photoelectric converters such as imaging devices and electronic flash control sensors. These light shielding elements enables the interior components of the camera to be visible therethrough, while ensuring that operational functions of the electronic camera are not adversely affected by entering unnecessary light.

  • Patent number: 5616289
    Abstract: An exchanging tower having excellent gas/liquid contact efficiency includes a packing which comprises an arrangement of a plurality of sheet-like bases (102), each of which is corrugated to form folds inclined along the longitudinal axis of the tower such that the folds cross one another. The corrugated sheet-like bases have plural continuous concave/convex channels formed on the surface thereof and extending in a horizontal direction. The packings are formed such that, when the packings are installed in the tower, in each corrugated sheet-like base a wall surface (107) of a concave channel above a crest (105) of the meander of an adjacent convex channel of the sheet-like base is located on an upper side along the longitudinal axis of the tower at a position higher than a wall surface (108) of a convex channel below a trough (106) of the meander of the convex channel.
