Patent JP-H0823083-A (JP)
Title: Manufacture of solid-state image sensing device
Inventor: HIDAKA YOSHIHARU
IPC: H01L27/146
Filed: 1994-07-08
Abstract: PURPOSE:To restrain a semiconductor substrate from warping extraordinarily and slipping off due to thermal deformation by a method wherein insertion conditions are so set as to make temperatures inside a high-temperature thermal treatment device and a thermal gradient on the surface of the substrate lower than certain values respectively when the substrate is transferred into the high-temperature thermal treatment device. CONSTITUTION:A water high-temperature thermal treatment device is composed of a tube 27 of open tube structure fitted with a gas inlet 26 and a heating heater 25. When the heater 25 is set in operation, an intra-oven soaking region 22 of constant temperature set at an actual start of a thermal treatment is present in the tube 27. As a certain thermal gradient is present at the end of the heater 25, a part of the tube 27 between the oven opening end 21 of the tube 27 and the starting end of the intra-oven soaking region 22 is designated as an oven opening-soaking region 23. The thermal deformation of a wafer is determined in size depending on the temperature of the oven opening end 21 and a temperature rise rate of the wafer in the oven opening-soaking region 23. Therefore, the temperature of the oven opening end 21 is set to a range of 450 to 520 deg.C, and a temperature rise rate of a wafer in the oven opening-soaking region 23 is set to a range of 1.5 to 3 deg.C/second.

Title: Magnetic head
Inventor: TERADA YOSHIO
IPC: G11B5/265
Filed: 1979-12-04
Abstract: PURPOSE:To eliminate effectively the noise of a magnetic head and thus obtain a high-quality reproduced signal, by providing a magnetic path at the core of a reproduction head to lead the magnetic flux to negate the feed-through magnetic flux. CONSTITUTION:The main core is formed by holding the gap component 14 between the I type core 11 and the C type core 12 of the reproduction head, and the auxiliary core 12 is provided on both side faces of the core 12. Then the winding 13 is applied by putting together both the core 12 and the center foot of the auxiliary core 15. As a result, the feed-through components phif1 and phif2 are synthesized with an opposite phase the each other within the windings 13, and the integrated magnetic flux phi becomes as phi=phiS+phif1-phif2. Here if phif1=phif2 is satisfied, phi=phiS is obtained. Thus the feed-through magnetic flux can be eliminated completely, and only the signal supplied from the tape can be extracted.

Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To detect deviation of the height of a magnetic tape at the time of recording operation. SOLUTION: When approach running in the case of succeeded writing is being performed (S008) in a repositioning operation at the time of recording, data recorded on a magnetic tape are read in and the height deviation is detected on the basis of these data.

When the occurrence of the height deviation is judged, the height deviation is detected again by the retry (S012-S016), and when the height deviation is detected even though the retry is carried out for the specified number of times, the error is fed back (S017) to a host computer.
