Title: Dma transfer control circuit
Inventor: TANAKA TOSHIO
IPC: G06F13/28
Filed: 1989-04-14
Abstract: PURPOSE:To efficiently read and write data by transferring data between plural I/O devices and a main storage device through a buffer memory connected between both the devices and storing transfer data and the device numbers of the I/O devices in the buffer memory. CONSTITUTION:When data transfer between the main storage device 2 and the I/O devices 4 to 6 is required, the I/O devices 4 to 6 send the data to be transferred and information indicating the device numbers of the I/O devices 4 to 6 indicate which I/O devices 4 to 6 transfer the data to an FIFO type buffer memory 7. When the data are transferred from the I/O devices 4, to 6, the buffer memory 7 outputs a DMA(direct memory access) transfer request to a direct memory access controller(DMAC) and DMA transfer is started between the main storage device 2 and the buffer memory 7. Even when DMA transfer requests are outputted from plural I/O devices 4 to 6, the queuing time can be reduced and efficient data transfer can be attained.

Title: Magnetic encoder
Inventor: SEKIGUCHI TOKIO
IPC: G01P3/487
Filed: 1988-04-18
Abstract: PURPOSE:To obtain the high-accuracy encoder by supplying a current to magneto-resistance effect elements of the magnetic encoder by a power unit which has a constant current circuit. CONSTITUTION:The magnetic encoder is constituted by magnetizing magnetic records 3 of a magnetic recording medium on the outer periphery of a magnetic drum 2 fixed on a rotary shaft 1 at nearly equal intervals in alternate N and S order and arranging the magnetic sensor 4 which has the magneto-resistance effect elements R1-R4 formed of ferromagnetic thin films oppositely to the outer periphery of the magnetic drum 2 across a proper gap. The current is supplied to terminals (a) and (b) of the magnetic sensor 4 by the constant current power source Is. Consequently, even if the resistance value R0 in the absence of a magnetic field varies with temperature, the current flowing to the magnetic sensor is constant, so the output voltage e1 between terminals (c) and (d) is only an output voltage based upon the variation of a magnetic field and never varies with the temperature.
