Title: Method for measuring magnetic brush development pressure
Inventor: YABANETA MASAZUMI
IPC: G03G15/09
Filed: 1987-11-27
Abstract: PURPOSE:To measure the pressure of an arbitrary area by providing a small hole on the periphery of a barrel, providing a thin film which covers the small hole, providing a probe in the way that it doesn't come into contact with the barrel and providing a detecting means for a loading pressure on a probe due to the deflection of thin film. CONSTITUTION:The small hole 2 is provided on the periphery of the barrel 1 and the thin film 3 is closely provided onto the barrel 1 in the way that the small hole 2 is covered with the thin film 3. The probe 4 extends inside the small hole 2 in the way that the probe 4 doesn't come into contact with the wall surface of the barrel 1. One tip of the probe 4 comes into contact with the thin film 3 and the other tip is connected to the sensitive surface of the load detecting means 5 of the barrel 1. Then magnetic brush pressure causes the deflection of the thin film 3 and the probe 4 is loaded on by the deflection. The load is detected by means of the load detecting means 5. With respect to probe 4 diameter, >=50%-width of the diameter of the small hole 2 is preferable. If the probe 4 diameter is too small, the deflection of the thin film 3 between the probe 4 and the wall of the small hole 2 becomes large and a measurement error increases.

IPC: G11B11/105
Filed: 1989-11-16
Abstract: PURPOSE:To obtain a magnetic field having uniform and sufficient intensity by providing plural projecting parts on the surface of a base consisting of a high-permeability and low-loss magnetic material and winding a conductor coil on each projecting part. CONSTITUTION:Plural projecting parts 3 are provided on the surface of a base 1 consisting of a high-permeability and low-loss magnetic material, and an conductor coil 2 is wound on each projecting part 3 as a core to form plural magnetic field generating parts. In this case, the coil 2 is wound on the side face of the projecting part 3, and the spacing between the turns is decreased. Meanwhile, since a strong magnetic field can be generated with a small number of turns because of the projecting part 3 as the core, the size of the projecting part 3 can be made very small, and a uniform magnetic field is obtained by uniformizing the distances between the projecting parts 3 as the magnetic field generating part and a recording medium.

Title: Method for dry-etching multilayered resist
Inventor: SATO JUNICHI
IPC: H01L21/3065
Filed: 1990-11-02
Abstract: PURPOSE:To speed up multilayered dry-etching and to improve anisotropy by making the etching gas contain at least O2 gas and Br-based gas or F-based gas in addition to them. CONSTITUTION:After transistors are formed on a silicon substrate 1 and coated with a lower layer wiring 22 for its patterning, it is entirely overlaid with an insulating layer 23 such as SiO2 or the like. Further, a base material layer 2 made of Al or the like, a lower resist layer 3 of polyimide or the like, an SGO intermediate layer 4, and an upper resist layer 5 are formed one after another. For example, CBr4 and O2 with a flow rate ratio of 30:70 and a pressure of 5-10mTorr are used as the etching gas, this multilayered resist layer is gradually etched away finally to obtain a wiring pattern 7 of the base layer 2. Even this way of etching with O* radicals under a high pressure allows anisotropy to be kept enough by mixture of Br-based gas, thereby suppressing deposit of the base material layer 2 onto the resist layer 3. This can speed up multilayered dry-etching and improve anisotropy.
