Title: Head position correcting system for magnetic disk device
Inventor: WATANABE YUSUKE
IPC: G11B21/10
Filed: 1987-08-26
Abstract: PURPOSE:To improve a head positioning accuracy and to increase a memory capacity by reading the servo information of respective tracks, detecting the misregistration quantity at respective servo positions and correcting the misregistration quantity between two adjoining parties of respective detected misregistration quantities. CONSTITUTION:When a magnetic disk 1 is rotated, respective pieces of information of the track for detecting the misregistration are read by a magnetic head 3, and the misregistration quantity of the head 3 is detected by an information reproducing circuit 6. The detected misregistration quantity is temporarily stored into a temporary memory circuit 7b respectively. A subtracting circuit 7d calculates deviation and an interpolation data register 7e successively stores respective deviations. Thereafter, when a seek instruction is inputted, the head 3 is positioned to a designated data track. Next, the servo information of the data track is read and temporarily stored into a temporary memory circuit 7c. An adder circuit 7f adds the deviation stored into the register 7e and the misregistration quantity stored in the circuit 7c, and calculates the misregistration quantity. Thus, the misregistration quantity is interpolated. The interpolated misregistration quantity enters a head driving circuit 8.

Title: Control circuit for data transfer
Inventor: SHIBAGAKI KOUICHI
IPC: H04L12/00
Filed: 1983-11-09
Abstract: PURPOSE:To simplify the line constitution by providing an FF set at the end of data transfer preparation and reset with a data acknowledge signal and ANDing an output of the FF and an external request signal. CONSTITUTION:A data request signal DRQ, a data acknowledge signal DACK and a data transfer preparation end signal DSOK are inputted from terminals 1-3. An FF4 is set to logical 1 by the DOSK signal 3 and reset to 0 by a signal da1 from an input terminal 10 of the DACK signal. A terminal 9 outputs the DRQ signal dr1 and inputs the DRQ signal dr2 externally. A terminal 10 outputs a DACK signal da2 and inputs the external DACK signal da1. In bringing the level of a DRQ signal 1 to logical 1 and a DACK signal 2 to logical 0, the terminal 9 goes to the transmission mode of the signal dr1 and the terminal 10 goes to the reception mode of the external da1, and in bringing the DRQ signal 1 to logical 0 and the DACK signal 2 to logical 1, the transmission/reception mode of the terminals 9, 10 is inverted. Thus, the constitution of a signal line is simplified.

IPC: H01L27/04
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To obtain a protection device for an integrated circuit that can satisfy a pressure-resistant standard with a higher surge voltage without requiring an excessive area. SOLUTION: While a resistor 13, a Zener diode 14, and a transistor 16 are electrically insulated one another by a trench 23 for insulation separation on a semiconductor substrate 19, a protection device 16 for an integrated circuit is formed. When a surge voltage Vs+ with positive polarity is applied to an input terminal 12, the Zener diode 14 conducts electricity in a forward direction, thus absorbing the surge voltage Vs+ via the resistor 13. On the other hand, when a surge voltage Vs- with negative polarity is applied, a base current flows to the transistor 16 for turning on the transistor 16 when the surge voltage Vs- becomes lower than the voltage of a power supply voltage Vdd by the amount of a Zener voltage Vz, thus conducting electricity between a power terminal 15 and an input terminal 12, adsorbing the surge voltage Vs-, and hence protecting an IC.
