Title: Erasing device
Inventor: WATABE KENJI
IPC: G11B5/024
Filed: 1988-01-29
Abstract: PURPOSE:To obtain a signal composed of continuous oscillation and damped oscillation by a simple circuit structure by executing a comparative operation by a first signal into which a reference signal is divided, a second signal into which the first signal is divided further and a third signal based on the position detection signal of a magnetic recording medium and obtaining an erasing signal. CONSTITUTION:The title device is provided with a 25-divider 3, a 2-divider 4 to further 2-divide an output from the 25-divider 3 and a comparator 5 to compare the output of a counter 2 with the output of the 25-divider 3. An output from the 2-divider 4 is compared with the output of the comparator and they are outputted from a gate circuit 6 based on a signal from a CPU 1. The two outputs are added by an adder 7 and it is filtered by a low-pass filter 8. Thus, the amplitude of an erasing current passed through the low-pass filter 8 becomes smaller gradually, a resistance division output becomes an intermediate potential and the erasing signal to be damped successively can be obtained.

IPC: H04Q9/00
Filed: 1989-01-27
Abstract: PURPOSE:To avoid duplicated transmission of transmission data when plural relay receivers receive the transmission data from the transmitter simultaneously by monitoring a multiplex signal line prior to the transmission of a received transmission data to the multiplex signal line from each of a wireless relay receiver and discriminating the presence of the transmission data. CONSTITUTION:When a wireless relay receiver 2 receives the transmission data sent from a wireless transmitter 1, after the validity of the transmission data is discriminated by the frame check or the like, the resulting data is stored in a data memory 26, and a multiplex transmission control means 21 monitors the multiplex signal line to judge whether or not the signal during transmission exists. As a result, when the presence of the transmission data during transmission is judged, the monitor routine mentioned later is executed, but when the transmission data during transmission does not exist, the transmission data stored in the memory 26 is sent to the multiplex transmission control means 21 by a data transmission means 27 and a multiplex signal according to a prescribed data is generated in the means 21 and sent to the multiplex signal line to be sent to the controller.
