Patent number: 7198656Abstract: 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.Type: GrantFiled: March 28, 2005Date of Patent: April 3, 2007Assignee: Toshiba Tec Kabushiki KaishaInventors: Ritsuo Takemoto, Masatoshi Tanaka, Hiroshi Yokoyama, Hitoshi Suzuki, Kiyoshi Ebe, Yoshihiro Tsuchiya, Ai Tanaka, Yasushi Nakatogawa, Ikuo Oshima, Yusuke Kinoshita, Yutaka Maeda

Publication number: 20060133061Abstract: 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.

Publication number: 20040066461Abstract: 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.Type: ApplicationFiled: October 6, 2003Publication date: April 8, 2004Applicant: Fuji Photo Film Co., Ltd.Inventor: Yutaka Maeda

Patent number: 6149364Abstract: 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).Type: GrantFiled: November 6, 1998Date of Patent: November 21, 2000Inventor: Yutaka Maeda

Patent number: 6115557Abstract: 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.Type: GrantFiled: July 22, 1998Date of Patent: September 5, 2000Assignee: Fuji Photo Film Co., Ltd.Inventors: Yutaka Maeda, Takayuki Hayashida, Yoshihiro Ishikawa, Keizou Uchioke
