Title: Mos field-effect transistor and manufacture thereof
Inventor: MURATA MICHIAKI
IPC: H01L21/316
Filed: 1990-06-30
Abstract: PURPOSE:To arrange that hydrogen-terminated silicon atoms are hardly returned to an interface level by hot electrons generated during an operation and to stabilize an operating characteristic by a method wherein silicon atoms bonded to halogen atoms are contained in a gate oxide film near a drain region. CONSTITUTION:A gate electrode 6 is formed; and after that, it is heat-treated in an atmosphere of a mixed gas of a halogen element, e.g. chlorine Cl2, oxygen O2 and nitrogen N2. The chlorine creeps from the surface of a gate oxide film 3; it is diffused into the gate oxide film 3; and it is bonded to interface-level silicon atoms 7 near the boundary between the gate oxide film 3 and a silicon substrate 1. As a result, bonding pairs of silicon atoms having no bonding partner are terminated at the chlorine and are changed to chlorine-terminated silicon atoms 15. Since the bonding strength of chlorine atoms Cl to silicon atoms Si is stronger than the bonding strength of hydrogen atoms 11 to silicon atoms Si, their bonded state is not detached by hot electrons. Consequently, electrons during an operation are not scattered and an operating characteristic is not worsened.

Title: Magnetic recording material
Inventor: ISHIGURO IKUO
IPC: G11B5/64
Filed: 1983-09-19
Abstract: PURPOSE:To obtain a magnetic recording material of a high density and high output by closely providing a horizontal magnetically anisotropic layer having a horizontal magnetic anisotropy against the surface between a vertical magnetically anisotropic layer and barrier layer. CONSTITUTION:When a magnetic head (not shown in the figure) is installed to a surface 2' only, lines of magnetic force coming out from the N-pole of the magnetic head reach a horizontal magnetically anisotropic layer 5 having a relatively good magnetic permeability after passing through a vertical magnetically anisotropic layer 3 and the lines reach the S-pole of the magnetic head after they are narrowed down in the layer 5 and pass through the layer 3. Since the layers 5 and 3 closely contact with each other and no barrier layer 4 and aluminum or its alloy 1 exist between them 3 and 5, the lines of magnetic force easily reach the horizontal magnetically anisotropic layer 5 and, since the lines of magnetic force narrowed down in the layer 5 is prevented from expanding when they pass the layer 3 before reaching the S-pole, the magnetic flux density increases.

Title: Reproduction signal binary-coding circuit
Inventor: NAGASAWA MASAYA
IPC: G11B20/10
Filed: 1992-06-08
Abstract: PURPOSE:To enable preventing the missing of a binary-coded signal while removing noises of a reproduction signal with a simple construction by using a gate circuit adapted to block the passage of the binary-coded signal of a long mark interval part. CONSTITUTION:A differentiation device 21 differentiates a reproduction signal from an optical pickup or the like and a first comparator 23 compares an output of the differentiation device 21 with a specified reference voltage to output a binary-coded signal. Then. a gate signal generation circuit 27 generates a gate signal which becomes active corresponding to a mark interval part larger than a specified value in the reproduction signal. A gate circuit 25 blocks the passage of the binary-coded signal to be outputted from the first comparator 23 when the gate signal is active and lets the binary-coded signal pass when it is not active. Thus, the gate signal always becomes inactive at a part with a narrow mark interval to prevent failed detection of a falling signal thereby enabling the removal of noises at a part with a larger mark interval accurately.

Abstract: PURPOSE:To confirm whether or not an original is a read completion original visually by attaching an identifier in accordance with a recording medium on the original. CONSTITUTION:A pair of original detecting holder detects the presence/absence of the original 20, and sets the original when no original 20 is detected, and a mark detecting means 13 judges whether or not a mark M exists on the original 20 i.e., the original is the one read once when the original 20 exists. When the mark M is detected, the attribute of the recording medium stored in a storage means 16 is compared with the mark M, and an operation is stopped when it is decided that it is the same original or same recording medium. Also, the original 20 is fed when no mark M is detected and no correspondence between the original and the recording medium is obtained, and also, the mark M is printed on the original 20 by an attaching means 13. Thence, a reading means 12 reads an image by the operation of a function key 3, and also, the image is recorded on the recording medium 9 by a recording means 11 by operating the function key 3, and the original 20 is ejected to an ejection port 6.

Abstract: PURPOSE:To form a loop at the biting side of pinch rolls and to prevent the slip flaw of pinch rolls generating at the time of slip by decreasing a wrap angle of strip around the pinch roll after the tail end of the strip runs out from a final finish stand. CONSTITUTION:When the tail end of a hot strip 2 runs out from a final finish stand, a driving device 12 of a cylinder 10 is driven by the signal A of a load cell to extend the cylinder 10. And the hot strip 2 at the biting side of upper and lower pinch rolls 5, 4 is raised to form a loop 2' by raising an idle roll 9 to the position where its top end comes into contact with a tangent which touches the lower pinch roll 4 and a deflector roll 6. Thus a wrap angle of the strip 2 around the lower pinch roll 4 is made to approximately zero. Further, the loop 2' is also formed by the deflection due to the bending of strip 2 produced by decelerating the peripheral speed of a table roll 3 though a tension is given to the rear side of the strip 2, to synchronize the strip 2 with the peripheral speed of the roll 3.
