Abstract: A powder container includes a powder chamber for containing powder for forming images, a powder outlet formed in a face of the powder container, and a shutter assembly to open and close the powder outlet and including first and second shutters. The first shutter is movable between a sealing position to close the powder outlet and an open position to open the powder outlet and includes a pressed member to cancel retention of the first shutter at the sealing position. The second shutter includes a pressing projection that interferes with the pressed member of the first shutter and is movable between a shielding position to cover the pressed member without interference between the pressing projection and the pressed member and a releasing position to press the pressed member with the pressing projection.

Abstract: A reflective projection screen for receiving images, for a projector having short focal length of short projection distance, and particularly a reflective projection screen applicable to 2D and 3D imaging. The reflective projection screen has multi-incident angles where every reflection surface is prepared from a projection angle of the projected image and where incident angles are formed differently from each reflection surfaces so that the projection images from different angles are reflected into one direction.

Abstract: An image apparatus includes a screen, a detecting unit, a determining unit, an acquiring unit and a control unit. The screen is configured to display an image formed by an optical system and at least one detection position superimposed onto the image. The detecting unit is configured to detect information regarding focus of the optical system at the detection position. The determining unit is connected to the detecting unit and configured to determine whether the information regarding the focus is within a predetermined range. The acquiring unit is connected to the determining unit and configured to acquire first image information at the detection position when the determining unit determines that the information regarding the focus is within the predetermined range. The control unit is connected to the acquiring unit and configured to evaluate arbitrary second image information in the screen using the first image information.

Abstract: Descriptive location information is associated with and displayed with a photograph taken on a wireless communication device. The descriptive location information is derived from raw location data received from a global positioning system (GPS) receiver in the wireless communication device. The raw location data is cross-referenced with descriptive location information contained within, for example, look-up tables in a memory of the device. The descriptive location information describes the location where the image was taken, for example, a city, a landmark, a distance from a city or landmark, and is visible to a user on the image displayed on a screen of the wireless device or another device.

Abstract: A totally-enclosed traction motor for electric railcar including, a frame structure of totally-enclosed cylindrical shape which is provided with a window, a rotor shaft rotatably supported to the frame structure coaxially with the frame structure, a rotor of cylindrical shape coaxially fixed to the rotor shaft which is rotated with the rotor shaft as one body, a stator of cylindrical shape fixed to an inner surface of the frame structure coaxially with the rotor shaft with keeping a gap between an inner surface of the stator and an outer surface of the rotor, and a cooling body mounted to the frame structure so as to cover the window and provided with a plurality of heat absorbing fins fixed to the cooling body from the inside and a plurality of radiation fins fixed to the cooling body from the outside.

Abstract: In an alternator for a vehicle having field coils for generating rotating magnetic field and stator coils for generating alternating current voltages in response to the rotating magnetic field, each of three stator coils are wound on only one of three stator teeth provided equi-angularly in a two pole-pitch of the rotor so that coil ends of the stator coils exposed outside the stator teeth do not cross each other. Thus, all the coil ends are cooled equally by the cooling air and a temperature rise of the stator coils is minimized. In order to reduce magnetic noise the stator coils are grouped. The first group of coils are provided in contact with a stator core and a second group of coils. The first and second group of coils are shifted from each other by .pi./3 radian in electrical angle.

Abstract: An AC induction motor assembly includes first and second endshields at least one of which is of special construction for reducing material costs. The motor assembly includes a stator assembly and a rotor assembly having an associated rotor shaft, which are mounted between and supported by the endshields. The endshields are of a skeletal construction and include a plurality of truss members which are so configured as to permit the endshields to be made of different materials while retaining the same configuration. The truss members include two rails parallel with one another and oriented generally parallel to the axis of rotation of the rotor shaft, and a web extending between the rails, integral with them.

Abstract: An improved rotor end winding assembly for an electrodynamic apparatus includes a stack of conductive straps that are configured to turn about an end turn portion of a rotor and include a top strap, a bottom strap and a number of intermediate straps that are stacked between the top strap and the bottom strap. A space defined between the rotor shaft and the bottom strap is divided into a high pressure zone and a low pressure zone by a zone block. A stepped coolant passage defined in the stack includes an ascending passage that leads from the high pressure zone toward the top strap and in the direction of the zone block and low pressure zone, and a descending passage that leads from the ascending passage to the low pressure zone. As a result, coolant will flow from the high pressure zone to said low pressure zone to efficiently cool said stack of straps.

Abstract: Methods and apparatus to reduce wear on surfaces in sliding contact by inducing vibratory movement in one or more of the surfaces. The movement is substantially perpendicular to a plane of contact between the surfaces and substantially nonuniform across the area of contact. The nonuniform vibratory motion of one surface with respect to another results in small rotational vibration of one surface with respect to another even as contact is maintained between the surfaces. Rotational motions tend to decrease surface wear due to thermal mounding by moving the zone of actual contact with time; rotational motions also open temporary gaps between the surfaces which allow the escape of wear particles, thus decreasing subsequent abrasive wear. The invention may be applied to sliding electrical contacts, either linear or rotating, and to sliding frictional contacts, as in brakes and clutches.
