Title: Magnetic head assembly body
Inventor: YAMADA TADAHARU
IPC: G11B5/55
Filed: 1987-02-12
Abstract: PURPOSE:To improve following-up characteristics to a recording medium by inclining a longitudinal direction axis of the sliding surface or the floating surface of a head slider to a longitudinal direction axis of a suspension. CONSTITUTION:A head slider 50 is stuck to a finger 23 of the center of a gimbal spring 20 by setting a longitudinal direction axis A2 of its two floating surfaces 52a, 52b at an angle of 15 deg.-75 deg. to a longitudinal direction axis A1 of a load spring 10. A difference in flexibility in the longitudinal direction of suspensions 10, 20 caused by the structure of the suspensions 10, 20 and the direction vertical thereto can be distributed almost equally in the rolling and pitching directions of the head slider 50 by attaching the head slider 50 by inclining it to the suspensions 10, 20.

Title: Lithium organic secondary cell
Inventor: YOSHIMITSU KAZUMI
IPC: H01M4/134
Filed: 1984-02-20
Abstract: PURPOSE:To reduce the inner resistance and improve the closed-circuit voltage and charging/discharging characteristics by coating a current collector substrate with a metal hard to be alloyed with lithium and having good electron conductivity and further with a metal liable to be alloyed with lithium on it to collect the current on the negative electrode side. CONSTITUTION:A current collector substrate 2a made of stainless steel is coated with a metal hard to be alloyed with lithium and having good electron conductivity and further with a metal liable to be alloyed with lithium on it to collect the current on the negative electrode side. Thereby, the conductivity of the stainless steel surface is prevented from being deteriorated due to an oxide film, and also the contact resistance between the negative-electrode lithium and the current collector is reduced due to the alloying of the outermost metal liable to be alloyed with lithium and the negative-electrode lithium. The intermediate metal hard to be alloyed with lithium and having good electron conductivity prevents the stainless steel surface from being exposed and giving an adverse effect to the charging/discharging characteristics due to the repeated charge/discharge. Accordingly, the inner resistance can be reduced, and the closed-circuit voltage and charging/discharging characteristics can be improved.
