Title: Dma transfer method and facsimile equipment using the same
Inventor: SUZUKI TAKAO
IPC: H04N1/21
Filed: 1995-02-01
Abstract: PURPOSE: To perform large capacity DMA transfer with a small capacity memory without intervention of a CPU by respectively counting word (byte) data transferred in input and output directions seen from a storage means and controlling transfer corresponding to the difference of both count values. CONSTITUTION: The DMA transfer is performed by outputting the transfer address of a channel to be operated at a transfer address generating part 13 while counting the number of times of transfer for each channel at a transfer number count part 14. At such a time, in the case of I/O at different transfer speed, a transfer number managing part 15 manages the number of transfer on the input and output sides so that overwrite or overread can not occur. Namely, the transfer number managing part 15 manages the number of times of transfer in the direction of inputting to the storage means and each time the data transfer in the input direction is once performed, the number is counted up just for '1' but each time the data transfer in the direction of outputting from the storage means is once performed, the number is counted down just for '1'.  Thus, the over-read on the input side and the overwrite on the output side can be prevented.

Title: Thin-film magnetic head for perpendicular magnetic recording
Inventor: TAKAHASHI JUN
IPC: G11B5/127
Filed: 1994-02-09
Abstract: PURPOSE:To improve recording and reproducing characteristics by providing an auxiliary magnetic pole with a projecting part, thereby shortening the spacing between the auxiliary magnetic pole (projecting part) and a main magnetic pole and averting leakage of magnetic fluxes without shortening the length of cores. CONSTITUTION:The auxiliary magnetic pole 5 of the thin-film magnetic head for perpendicular magnetic recording is provided with the projecting part 5a at the end of a recording medium and is formed to an approximately L shape. The spacing between projecting part 5a and the main magnetic pole 1 is set at, for example, 15 to 60mum. As a result, the spacing between the main magnetic pole 1 and the auxiliary magnetic pole 5 is shortened and the leakage of the magnetic fluxes is suppressed without decreasing the winding number of coil 7. The recording and reproducing characteristics are thus improved.

Title: Magnetic bubble memory device
Inventor: ISHIDA KAZUHIRO
IPC: G11C11/14
Filed: 1981-02-06
Abstract: PURPOSE:To prevent the absence of information by holding operation until transfer-in operation from a write major line ends even if a power supply break prediction signal is generated after magnetic bubbles are transferred out to a read major line. CONSTITUTION:A flip-flop 11 is set by a transfer-out signal TOUT and reset by a transfer-in signal TIN. When a power supply prediction signal PD arrives after the TOUT and before the TIN, the output Q of the flip-flop 11 is reset, so the signal PD is stopped by an AND gat 12, so that a revolving magnetic field stop signal HRSTOP is generated after the signal TIN is generated.
