Title: Manufacture of ferrite substrate thin film magnetic head
Inventor: TERADA NOBUHIRO
IPC: G11B5/31
Filed: 1993-12-22
Abstract: PURPOSE:To form a ferrite substrate thin film magnetic head accurately and with higher mass productivity. CONSTITUTION:After the application of an etching mask, a chemical etching is performed using an aqueous solution of phosphoric acid or the like to form an air bearing part 17. A protective film 13 is left without etching. Then, the height of the protective film 13 other than the air bearing part 17 is made lower than the surface of the air bearing by mechanical working using a grind stone or the like. This makes possible the checking of possible chipping or the like during the sliding of a disc thereby achieving higher reliability of a magnetic disc. The height of the protective film 13 may also be lowered by an etching using the etching mask used in the formation of the air bearing part 17 as mask again.

Abstract: PROBLEM TO BE SOLVED: To realize a system without requiring an angle measuring sensor for a monitoring station by inputting the output of each monitoring station versus each satellite broadckting azimuth calculator to an observation equation constitution equipment. SOLUTION: Each monitoring station 2i (i=1, 2,..., n) outputs a time when an radio wave is transmitted from each satellite by a receiver 4i and outputs a time when an radio wave is received by a clock 5i. The time is compared by a pseudo distance calculator 6, and a value obtained by multiplying the difference by a light speed is inputted to an observation equation constitution equipment 10 as a pseudo distance from each monitoring station to each satellite.  Also, each monitoring station versus each satellite broadcasting azimuth that each monitoring station versus each satellite broadcasting azimuth calculator 9 outputs and the position of each monitoring station that each monitoring station position memory 7 outputs and each satellite broadcasting position that each satellite broadcasting position calculator 8 outputs are inputted to the observation equation constitution equipment 10.
