IPC: F01P5/02
Filed: 1995-04-05
Abstract: PURPOSE: To reduce projected area to an air current direction so as to minimize the pressure loss of a net by forming the element wire of the net of a curved thin plate, and forming a support stay of a flat bar. CONSTITUTION: Element wires 3 are formed of curved thin plates of circular arc shape cross section and equal wall thickness and assembled to a support stay 4 so that the circular arc inlet angles of the element wires 3 are radially fromed from the center of a fan 1. The support stay 4 is formed of a belt-like flat bar and assembled by welding in such a direction as to obtain minimum projected area from the inflow direction view of an air current (a). The element wires 3 formed of the curved thin plates are thereby enlarged in width in an air current direction so as to secure strength and reduced in width in the right- angled direction to the air current so as to reduce pressure loss. In addition, the front edge is turned in the spiral angle direction of an air current at the outlet of the fan 1, while the rear edge is turned in a right-angled direction to the net face.  The same flow rate is thereby kept so as to recover useless turning vector pressure, thereby increasing the flow rate of the fan 1 while reducing noise.

Title: Paper sheet conveying device
Inventor: FUKUMURA ATSUSHI
IPC: H04N1/00
Filed: 1993-04-07
Abstract: PURPOSE:To provide a sheet conveying device to perform reliable conveyance of sheets without using a high torque type motor. CONSTITUTION:The drive roller 24 of a conveyance roller 22 to which the drive force of a motor is transmitted is arranged inside the bent part K of a document conveyance passage. This constitution causes the increase of a contact angle alpha between the drive roller 24 and a document G is sharply increased, a friction force therebetween is increased, and the document G is brought into reliable contact with the outer peripheral surface of the drive roller 24 without slipping. As a result, the energizing force of a leaf spring 26 through the force of which a driven roller 25 is energized toward the drive roller 22 side is decreased. As a result, a motor for rotating the drive roller 24 having low torque suffices for rotation of the drive roller. Thus, since the document G is reliably conveyed with the aid of a lowcost low torque type motor, a consumption power is reduced to a low value.

Title: Data transmission system
Inventor: YAMAGUCHI SHOJI
IPC: H04L13/00
Filed: 1987-04-03
Abstract: PURPOSE:To improve the processing performance of a transmission side transmission equipment and to simplify an interface part by executing the flow control only with the internal processing of a reception side transmission equipment without informing the transmission side transmission equipment of the possibility and impossibility condition of the reception side transmission equipment. CONSTITUTION:When a transmission equipment 11 receives the data from a transmission equipment 12, the transmission equipment 12 synchronizes to a clock ST sent from the transmission equipment 11 by a timing signal line 13 and by a reception data line 14, data RD are transmitted at a prescribed information quantity unit, for example, at a bit unit. When a buffer busy occurs while the transmission equipment 11 receives the data RD, the sending of the clock ST to a timing signal line 13 for transmission data of the transmission equipment 12 is stopped. Thus, the transmission equipment 12, while the clock ST for transmitting is stopped, stops the data transmission to the transmission equipment 11. Since when the buffer busy of the transmission equipment 11 is released, the transmission equipment 11 starts to send the clock ST to the timing signal line 13 again, the transmission equipment 12 restarts the data transmission to the transmission equipment 11. Consequently, only with the internal processing of the transmission equipment 11, a flow control is executed.
