Title: Diffusion method and its device
Inventor: KUROIWA TORU
IPC: H01L21/31
Filed: 1990-06-15
Abstract: PURPOSE:To get a diffusion method which can produce a desired pure film on a wafer without fixed pressure gas atmosphere including air by vacuumizing a reactor, and filling up it with nitrogen gas to fixed pressure. CONSTITUTION:A wafers is loaded on the boat inside a load lock room, and the load lock room 9 is sealed airtightly, and further a reactor 1 is blockaded by a gate valve 10. When the vacuumization of the reactor 1 and the load lock 9 is completed, the boat 7 loaded with a wafer is charged in the reactor 1. In this condition, the inside of the reactor is highly vacuumized secondarily. And, nitrogen gas is supplied. Pure oxygen gas is mixed in the nitrogen gas to be supplied, and in the reactor 1, a pure oxide film is produced on a wafer. Since the air inside the reactor is exhausted completely and further nitrogen gas is supplied this way, wafer treatment can be done in the condition that the air inside the reactor is completely replaced with nitrogen gas.

Abstract: PURPOSE:To obtain a shockless electromagnetic change-over valve by providing first and second coils as well as first and second springs, so as to open a spool in two steps, and whereby variably setting the initial opening of the spool. CONSTITUTION:When a magnetic field is generated on a first coil 11, a suction force is generated between a plunger 7 and a stopper 2a. The suction force is transmitted from a spool 14 to a retainer 15, which is moved, since the pre- load of a first spring 16 is overpowered by the suction force, and, by receiving the reaction of a second spring 19, it is stopped at an initial position, while the spool 14 is stopped, and is opened to the degree of opening of a first set flow. When a second coil 12 is excited, the first and second springs 16 and 19 are compressed, and the spool 14 is opened to the degree of a second set flow. Since the second spring 19 is in an adjustable condition, it is preliminarily compressed, and the initial position is thus variable, and various shock can be taken by an electromagnetic change-over valve, according to various degrees.

Title: Magnetic head and manufacture of the same
Inventor: MURAMATSU TETSUO
IPC: G11B11/10
Filed: 1990-06-13
Abstract: PURPOSE:To prevent a crosstalk from generating in plural adjacent magnetic domains on a recording medium by allowing a main magnetic pole which guides magnetic fluxes to a magneto-resistance effect element to be almost circular arc corresponding to the shape of the magnetic domains on the recording medium. CONSTITUTION:The magnetic fluxes from the magnetic domains on a recording medium 6 is guided through a main magnetic pole 30 to a magneto-resistance effect element 26. Then, information is reproduced based on the change of the electro-resistance value of the magneto-resistance effect element 26 in proportion to the size of this magnetic fluxes. In this case, the main magnetic pole 30 which guides the magnetic fluxes to the magneto-resistance effect element 26 is almost circular-arcuate corresponding to the shape of the magnetic domain on the recording medium 6. Thus, the crosstalk is prevented from generating in the plural adjacent magnetic domains on the recording medium, and a sufficient output of a regenerative signal can be obtained. Therefore, an accurate reproduction can be realized even when recording bits shape the almost circular arc magnetic domains after recording density is heightened at an optical assist magnetic recording.
