Title: Asynchronous bootstrap buffer circuit device
Inventor: KUMAGAI YUTAKA
IPC: H03K19/094
Filed: 1982-04-23
Abstract: PURPOSE:To improve the efficiency of a bootstrap without sacrificing the speed, by increasing the 1st input level of a buffer circuit with the 2nd inverting circuit after the switch is turned on with the output of the buffer circuit. CONSTITUTION:When the level of an output point A is increased, since transistors(TRs) T11, T15 and T16 are turned off, a point D goes to a high level, and a TRT18 keeps off. A TRT12 is turned off after a time t2 when the potential at a point B is lower than the threshold value VT of the TRT12 and a potential at a point C is increased with the charging of the TRT11. Further, a TRT16 is turned on after a time t3 when the potential at the point C exceeds the threshold value VT of the TRT16 and the potential at the point D is decreased. A TRT18 is turned off after a time t4 when the potential at the point D is lower than the VT of a TRT18, and a TRT17 charges up a capacitor C14. In this case, the increased component of the source potential of the TRT17 is fed back to the gate potential of the TRT11 with a bootstrap capacitor C11 and a capacitor C13, then the increase in the gate potential of the TRT11 is done rapidly independently of the potential change in the output point C of the buffer circuit.

Title: Semiconductor device
Inventor: AOKI MASAAKI
IPC: H01L29/78
Filed: 1988-03-23
Abstract: PURPOSE:To prevent development of leak current by forming a gate electrode through an insulating film on an SiXGe1-X layer shaped on an Si surface. CONSTITUTION:When an SiXGe1-X layer 2 is formed on a p-type Si substrate 1 by molecular beam epitaxy(MBE), an SiGe layer is formed by irradiating clean Si molecular beam and Ge molecular beam simultaneously to the Si substrate 1 in ultra-high vacuum. The SiXGe1-X layer 2 is formed on the Si surface 1 and an insulating gate 5 is shaped thereon in this way. Scattering of conductive electron is consequently reduced on a oxide film and a semiconductor interface owing to the effect of potential barrier between Si-SiXGe1-X. Leak current through a gate electrode can be thereby avoided.

Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To reduce lift up and down speed around full opening and closing positions of a window glass by gradually reducing a diameter of pulley toward wire wind starting position and wire wind ending position of the pulley and speed variation. SOLUTION: A pulley 10L winds a wire 6 when a window glass is opened, and one end of the wire 6 is fixed to a starting point of a spiral groove 11 positioned to the left side of the circumferential surface. While, a pulley 10R on the right side winds the wire 6 when the window glass 2 is closed, and the other end of the wire 6 is fixed to a starting point of a spiral groove positioned to the right side of the circumferential surface. Diameters of the pulleys in wire wind starting position and wire wind ending position of the pulleys 10L and 10R are smaller than their intermediate parts.

Title: Vertical magnetic recording system
Inventor: KAMISAKA YASUTAROU
IPC: G11B5/02
Filed: 1984-04-06
Abstract: PURPOSE:To set noises from the ground film of a medium to the degree of those produced when a Co-Cr single film is used, by setting the coersive force of a head making material to <=0.1Oe. CONSTITUTION:It is desirable as a reducing method of noises produced from a ground film to minimize the residual magnetism of a magnetic head. In practical ways, it is desirable to reduce the coercive force of the material for making the magnetic head to <=0.1Oe. In general, the residual magnetism of the magnetic head decreases as the coercive force decreases. Therefore, when a magnetic head having a smaller coercive force is used, noises produced from the ground film can be made smaller. Actually, when a magnetic head manufactured of a magnetic substance having a coercive force of <=0.1Oe is used, the ground film noises can be suppressed to a degree which is the same as that of noises produced when a Co-Cr single film is used. It is clearly understood from the figure that the ground film noises when a magnetic substance having a coercive force of <=0.1Oe is used for making the magnetic head are the same level as that of the noises produced when the Co-Cr single film is used.

Title: Ink jet recorder
Inventor: SAITO KOICHI
IPC: B41J2/01
Filed: 1989-03-20
Abstract: PURPOSE:To provide a small-type ink jet recorder free of pulsation and not affected by environmental conditions by generating a pressure for ink jet recording by a centrifugal force arising from the rotation of an ink. CONSTITUTION:A magnet 101 is disposed on the inside of a ring-shaped tubular container 102, in which a magnetic ink 103 is placed. The ink 103 in the container 102 is attracted by the magnet 101, and when the magnet 101 is rotated, the ink 103 is made to start rotating. At the start of the operation, a force exerted on the ink is directed toward the magnet 101, but when the rotational frequency is increased, the centrifugal force acting on the ink becomes greater than the magnetic force, so that a force directed outward from the center of rotation is exerted on the ink. The outward force is used as a pressure for supplying the ink to a recording head or as a force for ejecting the ink from the head, thereby performing ink jet recording. Thus, a constant pressure free of pulsation or the like is supplied, an ink jet recorder can be made smaller in size, and the effects of environmental conditions can be evaded.
