Title: Radio transmission system
Inventor: ITAYA EIJI
IPC: H04L12/28
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To allow a slave station to also conduct a relay operation by having only to provide a MODEM able to process only a base band signal for its own station to the slave station in the radio transmission system consisting of a master station and plural slave stations connected sequentially in cascade through radio channels. SOLUTION: Plural modulation waves received by a 1st reception means 2a are modulated by the spread spectrum system. Thus, a demodulation means 2b has only to have a capability processed by only a base band signal for its own station to demodulate the modulation wave for its own station among plural modulation waves. On the other hand, the plural modulation waves received by the 1st respectively means 2a are sent to an adjacent slave station 3 along a 1st transmission direction. Thus, relaying without modulation/ demodulation on its way is conducted.

CONSTITUTION:When the change of the rotational speed of a motor (A.C. motor) 7b for conveyance is presumed to be, for example, a straight line B and the rotational speed is reduced from a usual rotational speed P point to a Q point, the rotational speed of a motor (D.C. motor) for a stacker is reduced up to a Q' point with a necessary reduction ratio different from the straight line B as shown in a curved line C, rotation is executed more slowly and sheet paper or the like can be sent into the impeller of a stacker part without fail. When the rotational speed of the motor for conveyance is reduced lower than the usual speed and driving is executed, the rotational speed of the motor for the stacker can be reduced to the optimum speed by a program beforehand. Consequently, even for the type and condition of sheet paper or the like, highly accurate conveyance and lamination can be executed.

Abstract: PURPOSE:To find approximately a liquid level from a remote place and transmit the liquid level information as an electric signal by using a sensor by providing a scale plate and a pointer at the upper position of the main body of an apparatus, and mechanically moving the pointer with a float. CONSTITUTION:A liquid level indicator is fixed at a desired height of liquid level. When the liquid level rises up, a float 6 is moved upward along the inner wall of a float guide 4 accompanying the liquid level by the buoyancy of the liquid.
