Title: Actuator for optical disk
Inventor: OZAWA YASUYUKI
IPC: G11B7/09
Filed: 1988-10-04
Abstract: PURPOSE:To decrease high-order vibrations based upon rotary motion around the axis of a wire by providing an adjusting mechanism which adjusts the shunting ratio of currents flowing through actuator coils on both sides so that the center line of the driving force of the actuator passes the center of gravity of a movable part. CONSTITUTION:The movable part which includes an objective 2 and the actuator coils 3 and 4 is supported by at least four parallel wires 1. The coils 3 and 4 on both sides are connected in parallel and an adjusting function Rv for adjusting the shunting ratio of the currents flowing through both coils is provided on the connection point. This adjusting function Rv is, for example, a variable resistance and when the contact of the variable resistance is moved, the ratio of the currents flowing through both coils varies to increase the force of a coil where a large current flows, thereby moving the center line of the driving force. An adjustment is so made that the center line of the driving force passes the center of gravity of the movable part. Thus, such characteristics that the high-order vibrations by rotation do not depend upon a low frequency range are provided and the actuator is manufactured at a low cost with a good yield.

Title: Production of sintered ore
Inventor: TOKUNAGA MASAAKI
IPC: C22B1/20
Filed: 1986-10-24
Abstract: PURPOSE:To improve low-temp. reduction degradation index (RDI) and to improve and stabilize the quality over the entire part of a sintered layer by obliquely charging a raw material for degrading RDI onto an upper layer of a pallet, sintering the material, disintegrating and sieving the ore after sintering and circulating and charging the under size. CONSTITUTION:The raw material for degrading RDI such as easy melting Robe River ore is obliquely charged to the upper layer of the pallet of a sintering machine and is sintered. The calcination is thereby executed at the decreased amt. of forming the melt and the degradation of RDI is prevented in the upper layer where air permeability is good and the calcination temp. is low. The compounding ratio of the RDI degrading raw material is low and RDI can be improved in the lower layer where the air permeability is poor and the temp. is relatively high. The sintered matter after the sintering is disintegrated and sieved and the under size after the sieving is adequately circulated and charged to the upper layer and the lower layer. Since the returns are subjected to heat history, the degradation of RDI is obviated and the sintered ore having good quality is stably obtd.
