摘要:
A sheet transport device and an image forming apparatus that includes the sheet transport device. The sheet transport device includes a reverse-transport roller, at least one roller guide, and a shaft. The reverse-transport roller is provided to a diverging point of a sheet reversing portion from which a recording medium enters or exits and is configured to transport the recording medium to the sheet reversing portion. At least one roller guide is provided in a vicinity of an end face of at least one side of the reverse-transport roller and is configured to prevent the reverse-transport roller from contacting the recording medium when reversing the recording medium. The reverse-transport roller and the roller guide are disposed on the shaft. Friction of a peripheral surface of the roller guide is configured to be substantially less than that of the recording medium.

摘要:
An image forming apparatus includes a reversing unit which reverses and feeds recording material fed from a fixing device, and a guiding device including first and second guide members facing each other to form a part of a first conveying path in which a recording material with a toner image fixed thereto is conveyed to the reversing unit from the fixing device. The second guide member forms, in cooperation with a third guide member, a part of a second conveying path in which the recording material is conveyed to an outside of the main body of the image forming apparatus. The first and second guide members are movable between a sheet guide position in which the first and second guide members guide the recording material along the first and second conveying paths, and a sheet jam removing position in which each of the first and second conveying paths is opened for removal of a jammed sheet. A feeding device feeds the recording material fed from the fixing device through the first and second conveying paths, respectively, and a displacement device displaces the first and second guide members to the sheet guide position or the sheet jam removing position in cooperation with the reversing unit.

A color television cathode ray tube which comprises a phosphor screen formed of (A) a red-emitting phosphor selected from the group consisting of europium-activated rare earth metal oxide and europium-activated rare earth metal oxysulfide; (B) a green-emitting phosphor selected from the group cosisting of a mixture of copper-activated zinc sulfide and gold-activated aluminum-coactivated zinc sulfide and copper- and gold-activated zinc sulfide; and (C) a blue-emitting phosphor of silver-activated zinc sulfide, and wherein the green-emitting phosphor contains 0.005 to 0.02% by weight of copper and 0.005 to 0.15% by weight of gold based on the total amount of the green-emitting phosphor; and current running through the cathodes of electron guns for exciting the red-, green- and blue-phosphors can be made to have a substantially equal amount for the respective electron guns.
摘要:
Provided are an anti-icing system, wing, aircraft, and anti-icing method which prevent icing on the aircraft flying in an environment under icing conditions, using a simple configuration. An anti-icing system according to the present invention generates a pressure wave by aiming at supercooled airborne water droplets existing in a traveling direction of an aircraft (10) and thereby changes the water droplets into ice by means of the pressure wave. To impart an acceleration of, for example, 10 G to the water droplets, the pressure wave is set to produce 0.9 to 3.3 [Pa] at a predetermined location by taking attenuation into consideration.
