Title: Information signal transmitting and receiving device
Inventor: TAGUCHI KAZUYOSHI
IPC: G06F13/42
Filed: 1979-04-18
Abstract: PURPOSE:To prevent overrun of other I/O data and lowering of efficiency, by operating a response receiving circuit in a fixed period of time after a data request circuit has started its operation. CONSTITUTION:When a data request circuit 5 of I/O 20 has output a request signal to the service-in line 30, FF 7 is set at the same time. FF 7 is a signal which has been delayed by the delay circuit 8, and it is reset after a given period of time. When FF 7 has been reset, a response receiving circuit 6 becomes an operatable status, takes in a data from CPU 10 through the service-out line 40, and transmits it to the data transmitting and receiving control circuit 9. That is to say, since length of the lines 30, 40 is short and even if a response signal comes earlier than expected, it is not received by the response receiving circuit 6, a data on the OUT line 40 is not taken in. Accordingly, the efficiency is not lowered.

Title: Device for correcting offset voltage for hall element
Inventor: NISHIMURA KIYOSHI
IPC: H01L43/04
Filed: 1979-04-16
Abstract: PURPOSE:To hold the output of a device for correcting the offset voltage for a hall element at offset voltage being zero approximately by picking up a time sequential signal as an offset voltage, forming a phase difference between the signal and a reference signal, driving a counter with it to form an output for correcting the offset voltage. CONSTITUTION:When a terminal 22 is applied with a reset signal, a counter 19 and a flip-flop 20 are reset to close a gate 21, and a sawtooth voltage b is applied to the hall element 1 and a comparator 13. While the voltage b exceeds the positive offset voltage VOS, the output C becomes ''H'' level, to sequentially conduct transistors S1,... every time it is fed through a logic circuit together with a counted pulse output a from the flip-flop 10 and a counter 19 counts the pulse d to correct the voltage VOS at negative side. From the moment that the signal is inverted to negative, the counted input to the counter 19 becomes zero to allow the counter 19 to retain the counted value in the previous state, and any of resistors 61-6n are connected to the electrode 3. Therefore, the offset voltage is almost corrected and retained as it is.

Title: Magnetic disk device
Inventor: SHIOTANI AKIO
IPC: G11B5/00
Filed: 1994-03-18
Abstract: PURPOSE:To extend the life of an MR head by releasing feedback control for positioning a carriage and stopping flowing of a sense current into a magneto- resistance effect element of the MR head when the magnetic disk device is under the operational standby state. CONSTITUTION:When no command from a host device 14 and the operational standby state of the magnetic disk device are recognized by an interface and control circuit 11, the feedback control for the positioning is released by a servo control circuit 12. At the same time, a recording and reproducing amplifier 5 is controlled not to make the sensing current flow into the magneto-resistance effect element of the MR head by a recording and reproducing mode control circuit 6. Consequently, since the flowing time of the sensing current into the magneto-resistance effect element of the MR head 2 is drastically shortened, characteristics of the element can be prevented from being deteriorated by electromigration, etc., and hence life of the element is improved. Thus, an output of the MR head 2 is promoted without detriment to reliability, and performance of the high output magnetic disk device using the MR head 2 is enhanced.
