    摘要: A compressor has inlet guide vanes, rotor blades and stator blades. To prevent rotating stall, baffle vanes 5 capable of having their angles varied are installed upstream of the inlet guide vanes, actuators to vary the angles of baffle vanes are coupled to the baffle vanes, sensors installed upstream of the baffle vanes detect a rotating stall condition inside the flow passage of the compressor, and a control unit is responsive to signals from the sensors to output control signals to the actuators to vary the angles of the baffle vanes so as to prevent the rotating stall condition. Instead of the baffle vanes, fluid jets may be provided upstream of the inlet guide vanes for the same purposes.

    摘要: In exemplary implementations of this invention, a handheld, collapsible input device (CID) may be employed by a user to input and manipulate 3D information. The CID telescopes in length. As a user presses the CID against a display screen, the physical length of the CID shortens, and the display screen displays a virtual end of the CID that appears to project through the screen into the virtual 3D space behind the screen. The total apparent length of the CID, comprised of a physical portion and a virtual portion, remains the same (after taking into account foreshortening). Thus, the user experience is that, as the user holds the physical CID and pushes it against the display screen, the end of the CID appears to be pushed through the display screen into the virtual 3D space beyond it. The CID housing may include a push button for user input.

    摘要: An image forming apparatus includes an imaging unit for black and imaging units for other colors, a writing unit for black and a writing unit for other colors, a first heater corresponding to the imaging unit and the writing unit for black color, and a second heater corresponding to the imaging units and the writing unit for other colors. Turning ON/OFF of each of the first heater and the second heater are controlled separately. Thus, the first heater can be ON while the second heater is OFF.
