Title: Magnetic head device for magnetic disk
Inventor: KAWAMURA KATSUMI
IPC: G11B21/02
Filed: 1987-11-11
Abstract: PURPOSE:To improve the positioning accuracy and the floating accuracy of a magnetic head by making the joint part of the magnetic head for a carriage coincide with the node of proper oscillation in an oscillation system formed by the carriage and its bearing. CONSTITUTION:The carriage 1 on which the magnetic head 2 is mounted via an arm 2b and a flat spring 2a, etc., is guided by plural bearings 5a and 5b, and is positioned so that the node of the proper oscillation of the oscillation system formed especially by the mass of the carriage 1 and the spring function of 5a and 5b can coincide with the joint part 8 between the carriage 1 and the arm 2b. Since the position of the node of the proper oscillation depends on the position of center of gravity of the carriage 1, the arrangement of the bearings 5a and 5b, and the spring constants of the bearings 5a and 5b, etc., it is enough to adjust the center of gravity of the carriage 1, the arrangement of the bearings 5a and 5b, and the spring constants, etc., to coincide the position of the node with the joint part 8. In such a way, it is possible to improve the positioning accuracy and the floating accuracy.

Inventor: HASEGAWA HITOSHI
IPC: H01L21/316
Filed: 1985-12-16
Abstract: PURPOSE:To decrease leakage current of a Ta2O5 film formed by later oxidization process and be available for a stable material with a high dielectric constant, by selecting a lattice constant of a Ta film in a<=3.5Angstrom . CONSTITUTION:When a Ta film is made to grow to form Ta2O5, growth of the said Ta film is controlled so that a lattice constant (a) of Ta crystal satisfies a condition a<=3.5Angstrom . By growth in which the lattice constant of the Ta crystal becomes a<=3.5Angstrom , crystal structure for the most part becomes body centered cubic crystal system. When the Ta2O5 film is formed in this state, polycrystallization becomes hardest to occur. Thus, leakage current at the time of manufacturing completion can be remarkably decreased.

Abstract: PROBLEM TO BE SOLVED: To feed a stable power-supply voltage without increasing the number of external terminals by arranging at least either one of the first or second block for input/output of power supply between the first or second signal input/ output. SOLUTION: Firstly, a power-supply noise 18 caused by the operation of an internal circuit is conducted to a signal input/output block for the internal circuit. Then, a power-supply noise 19 caused by the operation of the signal input/output block for the internal circuit and the power-supply noise 18 are almost absorbed in a power-supply feeding source, before they are conducted to a signal input/output block for a high-S/N circuit which feeds a power-supply to the high-S/N circuit. This absorption is performed via a power-supply feeding input/output block and via a power-supply-noise absorbing routes 20, 21 whose impedances are very lower than the one of the conduction route to the high-S/N circuit.  The foregoing is the example of the case wherein only one-side of signal input/output block for the high-S/N circuit is adjacent to the signal input/output block for the internal circuit.
