Title: Adder circuit
Inventor: KOUNO KOUUN
IPC: H03B5/00
Filed: 1987-03-31
Abstract: PURPOSE:To ensure a prescribed output amplitude at a low current and low voltage by decreasing the current of a 2nd current source when the current of a 3rd current source of an adder circuit is increased so as to suppress the increase in the output amplitude when the current of the 3rd current source is increased. CONSTITUTION:If the control of a variable oscillator is deviated somewhat from the center, the control range of the output phase is kept to 45-135 deg. even with a small current of the current source of transistors(TR) Q3-Q6 by decreasing the current of the current source of TRs Q1, Q2 receiving a signal 6. Since the amplitude is not increased unnecessarily even in the control state, the cascade connection of TRs to a load is made possible. Thus, a prescribed output amplitude is ensured easily even at a low power voltage regardless of the adoption of the constitution, the TRs are connected in cascade to a load.

Title: Magnetic disk
Inventor: MISHIMA SACHIKO
IPC: G11B5/667
Filed: 1993-04-02
Abstract: PURPOSE:To provide a perpendicularly magnetized film having a high saturation magnetic flux density and high coercive force by adding W as a third additive element to a Co-Cr alloy thin film. CONSTITUTION:The magnetic alloy thin film consisting of Co-Cr (5 to 20at.%)-W(1 to 10at.%) is formed as the perpendicularly magnetized film 1 which generates magnetic anisotropy in the perpendicular direction of the plane of a disk-shaped magnetic disk substrate 2 on this substrate 2. W infiltrates into the hcp lattice formed out of the Co by addition of the W and the coercive force as the perpendicularly magnetized film increases according to this constitution. As a result, the coercive force sufficient for recording is assured even if the saturation magnetic flux density is increased by decreasing the ratio of the Cr contributing to lowering of the saturation magnetic flux density.
