Title: Method for measuring oxygen activity in slag, device thereof and consumption type crucible used for this device
Inventor: IWASE MASANORI
IPC: G01N33/20
Filed: 1989-10-17
Abstract: PURPOSE:To improve accuracy by housing a specific metal, the oxygen activity of which balances with the oxygen activity of slag and the slag in an iron crucible and measuring the oxygen activity in the specific metal. CONSTITUTION:The slag S and the specific metal M, such as, for example, copper or silver, which does not form an alloy with iron in an inert atmosphere, hardly forms an oxide and has the sp. gr. larger than the sp. gr. of the slag S are housed in the iron crucible 12. The crucible 12 is then imposed on a supporting base 7 in a reaction tube 1 and an inert gas is injected from a gas injection hole 5 to fill the inside of the tube. A melting furnace is operated to rapidly heat the tube and to melt the slag S an the metal M. A solid electrolyte 13 is lowered after the melting and the front end is immersed into the metal M. An oxygen concn. cell is then formed between a standard electrode with the electrolyte 13 and the metal M in-between and the crucible 12 of a reference electrode. The generated electromotive force is measured by a meter 16. The temps. of the slag S and the metal M are measured by a temp. element 8 and is indicated on a meter 11. The oxygen activity in the metal M is calculated by the arithmetic processing based on these two values. Since this oxygen activity balances with the oxygen activity in the slag, the oxygen activity in the slag is measured with high accuracy.

Title: Magnetic disk device
Inventor: MATSUMOTO TOSHIO
IPC: G11B21/21
Filed: 1988-10-28
Abstract: PURPOSE:To obtain the high output and the high resolution with a magnetic head set at the inner circumferential side of a magnetic disk and to reduce the head crush probability with a magnetic head set at the outer circumferential side by giving the floating characteristics to the magnetic head of the inner circumferential side so as to secure the smaller floating height than the magnetic head of the outer circumferential side against the same peripheral speed of the disk. CONSTITUTION:The floating surface width Wa of a magnetic head 13 set at the outer circumferential side of a magnetic disk 1 is set larger than the floating surface width Wb of the magnetic heads 11 and 12 set at the inner circumferential side respectively. Therefore the floating height of the head 13 is larger than those of the heads 11 and 12 against the same peripheral speed of the disk 1. Thus the floating height H3 of the head 13 is larger than the floating height H3' obtained with use of a magnetic head having the same floating surface width of both heads 11 and 12. At the same time, the floating height H1 and H2 of both heads 11 and 12 are smaller than the floating height H1' and H2' obtained with user of the magnetic heads having the same floating surface width as that of the head 13. As a result, the head crush probability is reduced with the head 13 and the high output and the high resolution are obtained with the heads 11 and 12 respectively.

Title: Device and method for separating sample and manufacture of substrate
Inventor: YANAGIDA KAZUTAKA
IPC: H01L21/02
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of defects in samples at the time of separating the samples. SOLUTION: A laminated substrate 101 is held between substrate holding sections 102 and 103 in such a way that the sections 102 and 103 press the substrate 101 against each other from both sides. While the substrate 101 is rotated, the substrate 101 is separated into single substrates from a porous layer 101b by a jet by spraying the jet from a nozzle 136. In the first stage of separation, the substrate 101 is pressed with a spring 117. As the separation progresses, the already separated parts of the substrate warp due to the pressure of the jet constituting medium (water) injected into the substrate 101. When the warping amounts become larger, the substrate holding section 103 retreats and a transmitting plate 120 comes into contact with springs 118 and 119. When the plate 120 comes into contact with the springs 118 and 119, the second stage of separation starts.  In the second stage, the substrate 101 is pressed by the springs 117-119. In the second stage, therefore, the laminated substrate 101 is pressed with strong pressing forces.
