Title: Feeding device of paper
Inventor: TSUNODA KENJI
IPC: B65H3/52
Filed: 1981-02-05
Abstract: PURPOSE:To prevent double feeding of paper by a method wherein the friction coefficient between a lower roller and the paper is made smaller than that between an upper  roller and the paper, and the lower roller is driven at a low speed to a direction opposite to paper feeding direction. CONSTITUTION:When paper P runs through a spot 2 the paper P is sent out by convex  tips of both an upper roller 3 and a lower roller 4 with pressure being applied on both  sides of the paper P. On this occasion a friction coefficient between the paper P and  an osculating convex surface of the upper roller 3 is made far bigger than that applicable between two sheets of the paper, and the upper roller 3 is made to rotate at a  speed and a direction identical with that of the paper P at its running. On the other  hand, the friction coefficient between the paper P and the osculating convex surface of the lower roller 4 is made bigger than that applicable between two sheets of the paper  and smaller than that applicable between the upper roller 3 and the paper P, and the lower roller 4 is made to drive at a low speed to a direction opposite to a running direction of the paper P as well. When two sheets of the paper are supplied in layers,  sending of two sheets of the paper in layers is prevented as successive paper is returned by the lower roller 4 at the spot 2, the upper paper alone is sent out by a bigger friction of the upper roller 3 and the successive paper is sent after the foregoing process.

Abstract: PURPOSE:To decide the connection state of an extension board at a high speed without increasing signal lines. CONSTITUTION:Request signal lines 121, 131, 141, and 151 which connect extension boards 12-15 to respective equipment main bodies 11 one to one are used and in a resetting period, the signal lines 121, 131, 141, and 151 are used to send signals for connection decision making. The equipment main bodies 11 hold the states of requesting signals from the respective extension boards 12-15 in registers 21. Specific signals are outputted from the connected extension boards, but not outputted from unconnected extension boards. This difference is read from the values of the registers 21 to decide the connection states. Consequently, the connection states of the extension boards 12-15 can easily be decided without providing dedicated signal lines.

Abstract: PURPOSE:To reduce the attracting noise of an attracted object by an appropriate current supply control by current supply control means at the time of attracting operation for an electromagnet which attracts the attracted object in combination with a permanent magnet. CONSTITUTION:A first current supply control means 3 which controls current supply means 2 and a second control means 4 which controls the timing of voltage supplied to an electromagnet MG from the current supply means 2 are provided. When the charged voltage of a first condenser C1 is supplied to the electromagnet MG, the charged voltage is raised from -E(v) to 0(v) over time and during this time, the repulsive force -F1 by the electromagnet MG is also gradually reduced to 0 over time. Accordingly, the attracting force acting on an attracted object 21 is gradually increased according to the gradual reduction of the repulsive force -F1. The attracting noise of the attracted object 21 can be reduced since the attracting force acting on the attracted object 21 at the start of attraction is made to be increased slowly over time.

Title: Spectrum spread communication equipment
Inventor: MOCHIZUKI NORIHIRO
IPC: H04J13/16
Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To reduce the deviation of an orthogonal axis and the phase/frequency deviation of a reproduced carried by diffusing/modulating an in-phase channel and an orthogonal channel through the use of different spread codes. SOLUTION: Transmission data #1 (data for in-phase channel) is spread/ modulated by a first spread code PN1 outputted from a code generator 14 in a first spread modulator 11 and is inputted to an orthogonal modulator 13. Transmission data #Q (data for orthogonal channel) is spread/modulated by a second diffusion code PN2 outputted from the code generator 14 in a second diffusion modulator 12 and it is inputted to the orthogonal modulator 13. Since spread modulation is executed by using the spread codes peculiar to the channels, the other channel signal is suppressed by the ratio of a mutual correlation value for a self correlation peak, the influence of the other channel signal for a demodulation signal is reduced and an error rate characteristic improves.  Furthermore, a permission range for the deviation of the orthogonal axis and the phase/frequency deviation of the reproduced carrier for realizing the desired error rate is enlarged.
