IPC: G04R20/12
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To obtain a method which obtains correspondence between information units and data signals even if a signal transmission system is greatly improved. SOLUTION: An information unit consisting of information units which are different in limited quantity is made to correspond to a signal part of specific length of a data signal which is transmitted by the signal transmission system and has noise superposed.

On the reception side of the signal transmission system, a different area part below the curve of a received data signal is found for each signal part. Evaluated values are made to correspond to the different area parts according to their sizes. On the basis of those evaluated values, it is determined which information unit is transmitted with the signal parts.

Title: Image recorder
Inventor: IJUIN KAZUYA
IPC: B65H7/02
Filed: 1988-09-13
Abstract: PURPOSE:To enable a platen roller to be disposed in an upper area of a recording sheet containing part, prevent a recording sheet from being inserted into a wedge-shaped part and jamming a device, and make the device small in size by disposing a sensor for detecting the presence of the recording sheet downstream of a recording head in a recording sheet feed direction. CONSTITUTION:A sensor 5 is disposed downstream of a thermal head 1 in the feed direction of recording paper 3. When the recording paper 3 is moved up to the end of a front wall 4a of a recording paper containing part 4, it necessarily abuts against a platen roller 2 to be prevented from moving upwards. Then, the roll-form recording paper 3 abutted against the platen roller 2 is separated from the front wall 4a of the recording paper containing part by the counterclockwise rotation of the platen roller 2 to be returned to the containing part 4. In this manner, there is no possibility that the recording paper may be inserted into a wedge-form part to jam a device even if the decrease of a recording paper diameter results in an unstable movement.

Title: Harmonic drive type electrostatic motor
Inventor: SAKATA MINORU

Filed: 1990-08-30
Abstract: PURPOSE:To prevent the slip of a rotor by the drop of the electrostatic attraction at the time of a rotor being contacting with gaps by arranging adjacent driving electrodes so that they may overlap each other in the axial direction of a stator casing. CONSTITUTION:A rotor 11 always contacts with plural driving electrodes P1, P2,... such that it straddles them as shown by an alternate long and short dash line beta. Therefore, when the rotor 11 rotates on the inside periphery of a stator 1 by the switching of the driving voltage applied to the driving electrodes P1, P2,..., the contact face of the rotor 11 shifts gradually from some driving electrode to the adjacent electrode, and it never gets in such condition that the rotor 11 contacts with only the gap 4 between the driving electrodes P1, P2,.... As a result, it can exert the leveled electrostatic attraction FRS upon the rotor 11 and the stator 1. Moreover, the minimum value of the electrostatic attraction FRS between the driving electrodes P1, P2,... also becomes large, and the slip of the rotor 11 can be prevented, and the output torque can be enlarged.
