Title: Paper aligning system and paper aligning method
Inventor: JIYON EI ANDAAUTSUDO
IPC: B41J13/26
Filed: 1990-09-21
Abstract: PURPOSE: To obtain an automatic sheet alignment (arrangement) system feeding a sheet to a sheet printing mechanism without relying on gravity and not exerting effect on the direction of a sheet tray by providing a drive means for selectively driving a main sheet feed roller performing the advance and rerversing of the sheet selectively. CONSTITUTION: A sheet feed alignment system feeds a stock of a printing medium like paper to a printing position successively from a sheet feed tray 40. When a sheet is drawn out by a rubber D-shaped roller 55, the sequence of alignment is started. The D-shaped roller 55 pushes the sheet in a roller meshing part until the whole of the front edge of the sheet 75 passes through the roller meshing part between a main sheet feed roller 60 and a pinch roller 65. Next, a motor is reversed and, since a clutch does not transmit reverse motion, the D-shaped roller 55 is not moved. The main sheet feed roller 60 and the pinch roller 65 push back the front edge of the sheet 75 from the roller meshing part but the D-shaped roller prevents the movement of the rear edge of the sheet 75. Therefore, distorion is generated between the roller meshing part and the D-shaped roller 55.  This distortion functions so as to take the alignment of the front edge of the sheet 75 with respect to the roller meshing part.

Title: Range hood with broiling device
Inventor: NAKAMURA MASAJI
IPC: F24F7/06
Filed: 1988-10-07
Abstract: PURPOSE:To prevent smoke or offensive odor from being filled in a room and further prevent oily smoke from adhering to a heat source by a method wherein an air blowing part for generating an air flow is arranged between the heating source arranged at a range hood and a heated article. CONSTITUTION:When a broiling cooking is carried out, interior air is sucked by a motor 3 and a vane wheel 4 constituting a normal ventilation fan within a range hood 2 and then an air stream from an air blower 10 generating an air curtain flow is simultaneously sucked. Since a heating source at the heating part 5 heats a heated article 9 with its radiation heat, it may not be influenced by the air curtain, and the article can be heated. Due to this fact, only the generated oily smoke is discharged out of a room without being adhered to an infra-red rays transparent glass 7 due to an air curtain flow. In this way, all the smoke and offensive odor are collected by the range hood, smoke or offensive odor is not filled in the room, stains caused by the oily smoke of the heating source are reduced and a troublesome cleaning work can be eliminat ed and a clean state can be maintained, thereby.
Patent JP-H0299370-A (JP)
Title: Paper feeder
Inventor: ASANO JUNICHI
IPC: B41J13/076
Filed: 1988-10-07
Abstract: PURPOSE:To increase an access angle of recording paper to a separation pad to improve a performance of separating paper one by one by determining the diameter of a separation roller to be a specific value or less. CONSTITUTION:With a separation roller 65 having a large diameter (38-40mm), an approach angle of recording paper to a separation pad 66 is relatively small (20-30 degrees). As a result, a drag of the separation pad acting on the recording paper is decreased. In addition, a frictional force acting on the separation pad is reduced for decreasing a back tension, thereby being inferior to a frictional force of the second and succeeding recording paper acting on the first recording paper to be fed, and a lap feed is very easy to generate. Therefore, if the diameter of the separation roller 65 is decreased to be 30mm or less, an approach angle to the pad 66 is as large as 30-45 degrees; therefore, a drag of the separation pad 66 on the recording paper is increased, and a separation performance is improved. In this manner, an overlapped feed is very hard to generate even if a frictional force on the separation pad is reduced for decreasing a back tension.
