Title: Height adjustment method and device therefor
Inventor: MAEDA SHINICHI
IPC: B60G11/26
Filed: 1994-10-13
Abstract: PURPOSE: To properly adjust height and eliminate the occurrence of a useless adjustment operation by increasing or decreasing the air pressure only for the required adjustment value obtained from a difference between mean detected height and reference height. CONSTITUTION: A travel speed is detected, and adjusting intervals are determined so as to corresponding to the speed. Furthermore, a controller 9 computes each of mean height values, depending on the measurement values of height sensors 6 to 8. The mean height values are, then, compared with reference height, and the required drive time of solenoid valves 15 to 20 is calculated on the basis of a difference found in the comparison at each position. Also, the intake solenoid valves 15 to 17 or exhaust solenoid valves 18 to 20 are released over the computed drive time for increasing or decreasing the air pressure of air springs 1 to 4. According to this construction, such a useless adjustment operation as in the case of height adjustment under feedback control can be eliminated and height can be quickly adjusted to the reference height.

Title: Paper feed device
Inventor: KOYAKATA SEIJI
IPC: B65H1/06
Filed: 1987-10-02
Abstract: PURPOSE:To make it possible to simply and surely set one or a plurality of originals by journalling a weight for producing a paper feed friction force, swingably to a fulcrum, and by forming a paper slide surface in a smoothly tapered shape so as to simply lift up the weight by a paper insertion force. CONSTITUTION:When a large number of paper sheets are inserted, a weight lift-up force component 38 becomes large with respect to an insertion force 37 since the taper of a weight plate 12 is small. Since the weight plate is swingable about a shaft 9, it mechanical loss is remarkably small. When a small number of sheets are inserted, these sheets 36 reaches at their leading ends the contact point 17 between a conveyer belt 5 and the forward end 6' of a separating belt 6' without making contact with a sheet guide 23 and the weight plate 12, and produces a paper feed force between themselves and the separating belt 5 when the latter is rotated. When the conveying belt 5 is moved to a position 5'' by means of a solenoid, the lower surface of a bent section 15 makes contact with the conveying belt 5, and accordingly, the action of the weight produces a paper feed force even at this place. Thus, it is possible to surely set originals irrespective of the number of sheets.

Abstract: PURPOSE:To provide the FSK data receiver suitable for circuit integration, with low power consumption and having an excellent characteristic by decreasing the scale of a high frequency circuit section requiring much power consumption and solving a problem of requirements for high stability of a local oscillation signal in the offset reception system with respect to the receiver for an FSK signal in the direct conversion system.
