Abstract: PURPOSE:To obtain a substrate material for a thin film magnetic head, which can improve hard sintering property and hard machinability, by adding the oxide of a specified rare earth material into a main component, which includes TiC and comprises Al2O3 for the remaining part, performing CIP treatment for these compositions, and thereafter performing sintering and HIP treatment. CONSTITUTION:A main component comprises 15-60wt.% TiC and Al2O3 for the remaining part. One or more kinds of Sc2O3, La2O3, CeO2, Pr6O11, Sm2O3, Tm2O3, Yb2O3 and Lu2O3 of 1-10wt.% among the oxides of rare earth materials is added to 100wt.% of the main component. Since wettability between Al2O3 and TiC is improved, sintering property is also improved. When an additive of 1-5wt.%, which indicates the grain growth aligning effect of one or more kinds of Cr2O3, TiO2, Y2O3 and MgO, is added, machinability is improved as a small grain diameter organization. When Si3N4 is further added, mechanical strength is improved. When this composition undergoes CIP treatment, the sintering temperature and the HIP treatment temperature in the succeeding steps are decreased. Thus, the uniform organization having a small grain diameter is obtained, and a substrate material for a thin film magnetic head having excellent sintering property and machinability can be formed.

Title: Dryer
Inventor: EZAKI SATORU
IPC: F16H7/08
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To dry clothing in good conditions, regardless of the quantity of the clothing to be dried, stored in a drum. SOLUTION: When the quantity of clothing C to be dried, stored in a drum 3, is not more than a reference value, the drum is rotated at a normal speed. On the other hand, when the quantity of the clothing C is more than the reference value, the drum 3 is rotated faster than the normal speed. In this way, the high speed rotation of the drum 3 for more clothing C increases the stirring performance of a baffle 6 to cause easy stirring of the clothing C in the drum 3. Good stirring of the clothing C in the drum 3 causes good heat exchange between heated air passing through the drum 3 and the clothing C, which leads to more efficient and quicker drying of the clothing.
