Inventor: NAGASAKA KEIICHI
IPC: G11B5/39
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To make an axis of easy magnetization of a free layer intersect at right angles to a magnetization direction of a pinned layer by arranging a second ferromagnetic layer on a first ferromagnetic layer having a first axis of easy magnetization which is separated from the first ferromagnetic layer and magnetized in a second direction substantially orthogonal to the first axis of easy magnetization, and providing an antiferromagnetic layer which under goes exchange link with the second ferromagnetic layer on the second ferromagnetic layer. SOLUTION: A structure is formed in a STEP 1 while a magnetic field of a predetermined direction is applied. A free layer 32 has a magnetization and an axis of easy magnetization in a direction shown by an arrow in the STEP 1. The magnetization direction of the free layer 32 in the STEP 1 is defined as a 0 deg. direction. A spin valve magnetic sensor is heat treated in a STEP 2 in a d.c. magnetic field acting in the 0 deg. direction. As a result of this, a magnetization direction and an axis of easy magnetization of a pinned layer 34 are agreed in the 0 deg. direction as indicated by an arrow in a STEP 3. Along with the heat treatment in the STEP 2, a magnetic shield or a magnetic pole of a magnetic head is also initialized in direction.

Inventor: NAGASU MASAHIRO
IPC: H01L29/749
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To avoid the concentration of currents and heat-generating parts and to reduce the inductance and the size of cooling facilities by arranging IGBT chips and diode chips, scattering them in a package under, specific conditions. SOLUTION: Arrangement patterns 1991 and 1992 for IGBTs 11 and diodes 14 in an IGBT package 1 are so chosen that four chips may form a quadrangle around one corner of an arbitrary chip, and they are the cases in which one diode chip 14 and two diode chips 14 are contained respectively. In either case, the number of diode chips 14 are three or less. Accordingly, in the IGBT package 1 the welding pressure of the chips becomes uniform, since the IGBT chips 11 and diode chips 14 are arranged being scattered. Further, it becomes possible to realize an IGBT stack having a superior cooling characteristic, and to reduce the size of cooling facilities for stacks, since currents are scattered and flow in the IGBT package, and heat-generating parts are not concentrated.

IPC: H01L31/04
Filed: 1987-09-30
Abstract: PURPOSE:To increase a photoelectric conversion efficiency within a semiconductor layer on the side to which light is applied, by a method wherein dopant diffusion with higher concentration than that at peripheries is provided to many partions and current is taken out from these partions via an electrode metal layer. CONSTITUTION:An N<+>-type semiconductor layer 2 with conduction opposite to that of a P-type semiconductor substrate 1 is formed on one surface of the substrate 1. A reflection prevention layer 5 is then formed over the whole surface of the N<+>-type semiconductor layer 2 and many several-mum-square holes are made therein. Then, high concentration N<++> semiconductor layer 9 is formed only on those portions where the holes are made by the N<+> semiconductor layer 2. An electrode part 4 is formed so as to electrically connect the holes 8 with the N<++> diffusion part 9, and an electrode layer 6 is then formed on the underside of the substrate 1. With this construction, the contact resistance of the electrode 4 on the light projection side with respect to the N<+> layer 2 can be greatly reduced, which reduces a surface recombination current on the N<+> layer 2 and enhances a photoelectric conversion efficiency.

Title: Position detecting device
Inventor: TOMITA KOHEI
IPC: G01D5/30
Filed: 1987-09-30
Abstract: PURPOSE:To perform secure position detection even if the side face of a stage is stained by holding the output of a photoelectric converter when a light beam from an optical means is all projected on the reflecting surface of a mirror surface body. CONSTITUTION:This detecting device consists of a sample holding circuit 22 which holds the output of a photodiode 18 when the light beam from the optical means 5 is all projected on the reflecting slanting surface of the mirror surface body 2 on the stage 1, a divider 23 which calculates the ratio of the held output level and the output of the circuit 22, etc. Then when constant-level intense reflected light from the diode 18 is obtained, the output level is held by using the circuit 22. Consequently, if the surface of the mirror surface body 2 is stained, the reflected light level varies gradually at the time of projecting the light beam with the same intensity, but the circuit 22 holds the intensity of the reflected light at the time of the total reflection to obtain the ratio of the reflected light at the position where the output decreases gradually from the end part of the reflecting slanting surface of the mirror surface body 2, so the accuracy of the surface due to staining is precluded and an accurate position signal is obtained.
