摘要： There can be solved a problem in which a lock range is narrowed by using an oscillator such as a ceramic having a high Q and a horizontal deflection frequency generating system compatible with all horizontal deflection frequencies of a variety of television systems cannot be formed without difficulty. This system includes a frequency-fixed oscillator oscillating at a frequency f0 sufficiently higher than a deflection frequency fh in a multi-scan display, a first counter for counting a clock outputted from said oscillator in a descending order, a duration in which an integer n which results from rounding a decimal point of a value obtained by a division of f0 fh is divided by an integer m smaller than n and said first counter counts a value k thus obtained k times is set to one cycle and a duration in which a second counter for counting a value m times repeats the counting m cycles is set to one period and thereby generating a deflection frequency fh.

摘要： A method of manufacturing a magnetic head, including a magneto resistance effect (MR) element that reads a magnetic recording medium, is disclosed. A multilayer film is formed on a shield layer. Unnecessary portions of the multilayer film are removed from both sides of the MR element in a first direction orthogonal to a lamination direction of the multilayer film and parallel to the MR element surface facing the magnetic recording medium. An insulating layer is formed on a surface exposed by removal of the unnecessary portions. An integrated soft magnetic layer covering both sides of the MR element in the first direction and an upper side of the MR element is formed, thereby configuring a second shield layer. An anisotropy application layer is formed on the second shield layer, thereby providing exchange anisotropy to the soft magnetic layer, and magnetizing the soft magnetic layer in a predetermined direction.

摘要： To provide a transmitting apparatus capable of suppressing the fluctuation of a common mode potential and performing high-speed, long-distance signal transmission. The transmitting apparatus has a main buffer circuit and a pre-emphasis buffer circuit 20. The pre-emphasis buffer circuit 20, which has a switch circuit 21, a first current source 22, and a second current source 23, uses the switch circuit 21 to output a current signal having the same direction as an output current of the main buffer circuit 10 during a certain time interval starting from a time point when the level of data to be transmitted changes, and brings the output terminals 201, 202 to a High-Z state during a time interval when the level is constant after a lapse of the abovementioned certain time interval. The output of the pre-emphasis buffer circuit 20 has no influence on the common mode potential of the output of the main buffer circuit but has influence only the amplitude of the current signal output to a differential transmission line. In this manner, the transmitting apparatus can suppress the fluctuation of the common mode potential and can perform high-speed, long-distance signal transmission.
