Title: Magneto-optical recording medium which is made discontinuous between tracks and permits over-writing
Inventor: SATOU MASAAKI
IPC: G11B11/105
Filed: 1986-12-05
Abstract: PURPOSE:To magnetize a recording layer and to form pits by magnetization of an auxiliary layer under application and projection of a recording magnetic field Hb and laser beam by superposing the recording layer which is discontinuous between adjacent tracks and has perpendicularly magnetic anisotropy having a prescribed relation of coercive force HC and Curie point TC and the auxiliary layer. CONSTITUTION:Between the tracks are made discontinuous to eliminate the influence of temps. TH, TL and coupling (recording) magnetic field Hb from the adjacent tracks. HC1>HC2, TC1<TC2 at a room temp. TR. The magnetization of both the layers is eliminated when the medium temp. is set at THapprox.=TC2 by projection of the laser beam L of a high level. The magnetic field Hb in the direction A or the direction opposite from A is applied to the medium according to the kind thereof to magnetize the auxiliary layer in, for example, the direction opposite from A, then the recording layer is air cooled in the presence of Hb and is magnetized in the opposite direction according to Hb, by which the pits are formed. The magnetization of the recording layer is annihilated and the magnetization of the auxiliary layer is not annihilated, thus the pits are formed at TLapprox.=TC1 by the projection of the low level beam. The magneto-optical recording medium which is made discontinuous between the tracks and permits over-writing is obtd. by this constitution.

Abstract: PURPOSE:To bring the peripheral device into the standby state without lowering the efficiency of a CPU by providing a means holding a standby request from the CPU and using a means displaying the execution of the instruction so as to inhibit the standby control signal. CONSTITUTION:While an instruction inputted to the peripheral device from a CPU (not shown) is being executed, a flag register 23 is set by a signal 36. When the standby request is inputted from the CPU, since the standby request signal 37 sets a flag register 24, the standby control signal 34 is not active. Thus, an internal clock 35 is not inhibited and no standby state is attained. When the instruction during execution is finished, the flag register 23 is reset by an end signal 31 and the standby control signal 34 is active, the internal clock 35 is inhibited to be in standby.

Title: Manufacture of semiconductor device
Inventor: OZAWA YOSHIO
IPC: H01L21/324
Filed: 1990-10-31
Abstract: PURPOSE:To sharply reduce the danger of a high-temperature heat treatment in a hydrogen atmosphere and to completely remove an oxygen precipitate by a method wherein, after a first high-temperature heat treatment has been executed in an inert gas atmosphere, a second high-temperature heat treatment is executed in an atmosphere which contains hydrogen gas. CONSTITUTION:By a first heat treatment process executed in an argon gas atmosphere, an interlattice oxygen concentration in a silicon wafer is reduced to 1/5 or lower at a depth of 5mum from the surface of the wafer as compared with that before the heat treatment. In succession, a second process is executed. First, a valve 3 at a hydrogen gas pipe is opened; high-purity hydrogen gas whose impurity content of moisture or the like has been reduced to 0.1ppm or lower is made to flow into at 1l/min. At this time, since residual oxygen inside a heat treatment furnace has already been replaced sufficiently with argon gas, a danger such as an explosion or the like which is caused when the hydrogen gas is introduced hardly exists. A residual oxygen precipitate, at about 0.1/cm<2>, which exists near the surface of the wafer by a reduction effect of oxygen disappears completely.
