Title: Magnetic recording medium
Inventor: DOI TSUGUHIRO
IPC: G11B5/73
Filed: 1989-06-21
Abstract: PURPOSE:To prevent sticking of dust and decrease in output and to realize high-density recording by making difference of a specified range between values of surface electric resistance of a recording side and a nonrecording side. CONSTITUTION:The recording medium has a magnetic layer for recording on one side and a magnetic layer not for recording on the other side. The surface resistance of the recording side is different from that of the nonrecording side by 1X10<6> - 9X10<11> OMEGA/cm<2>. The difference is determined so that the resistance of the nonrecording side becomes 5 - 10 times as large as that of the recording side. Thereby, the amt. of conducting particles incorporated into the magnetic layer or the base coat layer of the recording side is decreased, which enhances surface smoothness of the recording side. Thus, the obtd. medium can be used for high-density recording and shows no deterioration of output due to sticking of dust.

Title: Tdma frame counter control system for settlement of reception synchronization
Inventor: HATAKEYAMA IZUMI
IPC: H04J3/06
Filed: 1991-06-04
Abstract: PURPOSE:To omit the mode for production of a special control signal and also to omit the need of hardware for settlement of the reception synchronization in the TDMA communication. CONSTITUTION:In a reception synchronization settlement state, a mode register 500 is set in a reception synchronization mode with the control signal received from a controller which controls a slave station and via a controller interface 423. A reception TDMA frame counter 481 sets a slot including the reference burst given from the controller and a frame number to the load input via a correction register 482. Then the counter 481 loads cyclically the same slot and frame number so as to repetitively output them. When a synchronizing signal is detected after reception of the reference burst, the counter 481 is loaded for settlement of the synchronization. At the same time, the settlement of synchronization is reported to the register 500. Thus the initial stage is complete for settlement of the reception synchronization, and the periodical loading operations are canceled.

Filed: 1977-12-27
Abstract: PURPOSE: To take out a signal for determining the number of revolution, by connecting the rotor of a commutator-type motor via an impedance or a reactance element to a power source and detecting the variation in a current flowing through  the rotor thereby.  
     CONSTITUTION: A rotor of a DC super-mini-motor is connected in series with an impedance or a reactance element 8 across power source 7, and the variation in a current flowing through the impedance or reactance element 8 is detected for taking out a variation-signal 9. Since the variation in the impedance viewed from the power source 7 caused by the switching of brush contacting with the commutator as the rotor 6 retates produces a variation in the current to be taken out, a signal indicative of the number of revolution of the motor can be obtained without providing a particular detecting device.

Abstract: PURPOSE:To reduce instantaneous driving power by one half, by dividing a dot printing element into two sets and arranging the dot printing elements of both sets so as to be offset only at predetermined intervals while performing printing driving so as to shift timing by a predetermined time corresponding to said arrangement. CONSTITUTION:The dot printing elements H2, H4 of a second set are shifted by P/2 to the left side with respect to the dot printing elements H1, H3 of a first set.

Therefore, when the elements H1, H3 of the first set perform the dot printing of a11, c11, the elements H2, H4 of the second set are present at places respectively offset by an interval P/2 to perform no printing. Thereafter, when the elements H2, H4 of the second set perform the dot printing of b11, d11, the elements of the first set are shifted by P/2 to perform no dot printing. Therefore, driving power is reduced by half.
