Title: Method for detecting completion of melting of iron-containing cold charge
Inventor: YAMAJI CHIHIRO
IPC: C21C5/28
Filed: 1988-01-29
Abstract: PURPOSE:To detect the time when the melting of an iron-contg. cold charge is completed with high precision by measuring the low-frequency component vibrating force and all-frequency component vibrating force of the vibration of a converter body, and considering the time when the ratio of these vibrating forces reaches a set value to be the completion of melting. CONSTITUTION:An iron-contg. cold charge is charged into a converter, oxygen is blown in from a top-blowing lance, and carbonaceous material and oxygen are blown in from a bottom tuyere to melt the cold charge. In this case, the low-frequency component vibrating force and all-frequency component vibrating force (or high-frequency component vibrating force) of the vibration of the converter are measured, and the ratio of both vibrating forces is calculated. The time when the ratio reaches a set value is considered to be the completion of melting. By this method, the completion of melting of the cold charge can be precisely detected, even when the operating conditions such as the charge SM ratio, top-blown oxygen amt., and bottom-blown gas amt. are changed.

Title: Actuator supporting structure for magnetic disk device
Inventor: SUZUKI KAZUHIRO
IPC: G11B21/02
Filed: 1988-01-28
Abstract: PURPOSE:To prevent off-track from being generated by varying confronting plates in the same direction corresponding to temperature change in a housing. CONSTITUTION:When a current is permitted to flow on a voice coil motor 100, unified head arms (86-89) are rocked centering an actuator shaft 95. Thereby, each of heads (70-77) can make access to a targeted track on disks (65-69). At this time, the tightening force of a bolt 102 is set remarkably higher than that of a bolt 101. Therefore, when the temperature change is generated in the housing 61, deviation between plates 98 and 99 becomes the one centering the bolt 102. Also, the mounting position of the bolt 102 goes to a position confronting the upper part with the lower part of the housing 61, then, it coincides with the direction of the deviation. Therefore, it is possible to prevent the actuator shaft 95 from being inclined and the off-track from being generated.
