Title: Pulse delivery system
Inventor: HIRAIDE KAZUHIRO
IPC: H04L5/22
Filed: 1977-10-25
Abstract: PURPOSE:To reduce the cross talk due to continuous zero and to make easy the separation of the frame synchronizing signal, by picking up for timing with fundamental frequency. CONSTITUTION:The data and frame synchronizing pulse are inputted from the terminals 3 and 4 with NRZ code. The data inverted with the retiming circuit 5 is performed for 1 bit inhibit only when the frame synchronizing pulse is incoming with the inhibit gate 6. The 1/4 frequency divider 8 counts down and makes the level with the MSD bit when the input code of the terminal 3 is O. It is made with the clock pulse inverted with the code conversion circuit 10 to the data of the code 1. The input signal O memorized in the 1 bit shift register 9 displays the state before by 2-bit out of O at the output side of the shift register 9, then this is synthesized with the circuit 11 and outputted. With this system, no timing information is disappeared, and the data train of two-values and the frame synchronizing signal can be delivered at the same time and the cross talk is also less.

Title: Magnetic disk device
Inventor: TAKAGI NOBUYUKI
IPC: G11B5/02
Filed: 1984-06-25
Abstract: PURPOSE:To narrow the interval between mediums by shifting an upper head to the left and a lower head to the right from the same space as compared with the conventional device wherein the upper and the lower heads are opposed to each other in the same space. CONSTITUTION:Magnetic heads 22 and 23 are fixed by flexures 24 and 25 for supporting the heads, and the flexures 24 and 25 are further fixed by an arm 26. The arm 26 is moved forward and backward so that the heads 22 and 23 can be accessed onto a concentric track of a medium 27 to detect the signals.

Abstract: PURPOSE:To prevent the generation of printing shift at the time of printing operation due to each mode using one printing head sensor, by monitoring printing shift on the basis of the detection signal from the position of a printing head at least before printing operation is started or after printing operation is finished. CONSTITUTION:When a printing head 11 inputs a printing operation mode over a slip printing area PDs monitored, the printing area PDs and a journal printing area PDj during printing operation, an operation mode common control part 146 issues an order for moving the printing head 11 to a reference position SP to a printing head control part 142 and controls a printing head driving means 12 to allow the printing head 11 to move to the reference position SP. A printing head sensor 13 detects the printing head 11 to send a printing head detection signal to the common control part 146 through a printing head detection part 143 to set the printing head 11 to the reference position SP and the common control part 146 confirms the position of the printing head 11. Therefore, even when printing shift is present at the first position of the printing head 11, printing operation generating no printing shift can be performed.
