Title: Semiconductor coupled superconductive element
Inventor: TAKAYANAGI HIDEAKI
IPC: H01L39/22
Filed: 1985-01-24
Abstract: PURPOSE:To increase the electrode gap much more than conventional, and further to realize superconductive two-terminal or three-terminal elements excellent in characteristics, by containing a two-dimensional electron gas formed at the junction interface between different semiconductors and two superconductive electrodes in ohmic contact with the semiconductor in which the two-dimensional electron gas is formed. CONSTITUTION:The contact interface between a GaSb 3 and an InAs 4 is provided with a two-dimensional electron gas (2DEG) 5 on the InAs side having larger electron affinity than GaSb. The superconductive diffusion length xsiN ion the case of two dimensions is xsiNproportional mu<1/2>ns<1/2> from Formula I. Further, the 2DEG5 is formed in the n-type InAs, and the Schottky barrier height to the n-type InAs metal is negative and forms an ohmic contact Therefore, the electron tunnel probability Tj at the semiconductor/superconductor interface becomes much larger than that of p-type Si or the like. Since the values xsiN and Tj of the 2DEG formed at the InAs/GaSb interface are large like this, two-terminal action that superconductive current flows through the 2DEG is enabled, and the electrode gap L can be taken to 1.0mum or so.

IPC: B60N2/90
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a play of a hog ring and to prevent the generation of noise. SOLUTION: A seat is formed such that a bag-form suspension bag cloth 3 is sewn to the edge of a seat cover 2 with which the surface of a seat pad 1 is covered and a wire 4 inserted therein is coupled to the lock part 7 of a back panel 6 by means of a hog ring 5. In this case, the vicinity of the edge of a bag-form suspension cloth 3 is formed into a wire insertion part 13 and a cylinder part 14 for buffering by first and second sewing line juxtaposed with each other along a longitudinal direction. A play of a hog ring 5 is absorbed by the rebound force of a cylinder part 14 for buffering located between the wire 4, inserted in a wire insertion part 13m and the lock part 7 of a back panel 6.

Title: Electron gun
Inventor: FUKUSHIMA MASAKAZU
IPC: H01J29/48
Filed: 1987-01-23
Abstract: PURPOSE:To reduce a spot diameter of electron beams to minimize spherical aberration, by impressing respectively given voltages on the third to sixth grid electrodes and then specifying length of the fifth grid electrode. CONSTITUTION:The fourth grid 5 and sixth grid 7 are electrically connected, with phosphor voltage VB being impressed on them. The third grid 4 and fifth grid 6 are electrically connected, with focusing voltage VF impressed on them. Because the voltage VF impressed on the third grid 4 is small by factor of several numbers compared with the voltage VB, potential gradient between the second grid 3 and the third grid 4 becomes small, and spherical aberration of focusing lens formed there is remarkably reduced. Besides, length l5 of the fifth grid electrode 6 is made larger than a half of its inner diameter D. Hence, a spot diameter of the electron beams can be reduced even in a large-current region.

Abstract: PURPOSE:To simplify structure and to reduce cost by detecting the position moving amounts of a magnet, which is provided at a frame fixed to a rotating body, and the magnet of a mass body loaded on the frame so as to be freely rotated. CONSTITUTION:The rotational axial line of a mass body 2 is made coincident with a rotational axial line L of a rotating body (moving body) M and a frame 1 is fixed to the rotating body M. When the rotating body M is rotated in such a state, the frame 1 is rotated and the mass body 2 is also rotated to be pulled by the frame 1. At such a time, inertia moment is operated to the mass body 2 corresponding to angular velocity to be operated to the rotary object M. According to this inertia moment and the balance of a ring-shaped magnet 4 to energize the mass body 2 at a reference position with the magnetic force of a stator 5, the position of the mass body 2 to the frame 1 is determined. When the mass body 2 gets out of the reference position, the density of magnetic flux passing through a hole element 6 is changed and the output is changed. Therefore, by measuring this output change, the displacement amount of the magnet 4, namely, of the mass body 2 can be known and based on the displacement amount, the angular velocity of the rotary object M is detected.

Moreover, when the cam groove 18 is arranged in the direction to cross with the brush axis 33 at 45 deg., the brush axis 33 is reciprocated horizontally as rotating in both directions according to the rotation of the eccentric cam 13 in the clockwise direction. In such a case, since all modes can be provided by the rotation of the eccentric cam 13 in the clockwise direction, the motor 15 rotating in one direction can be used, which enables an inexpensive motor to be used, and the service life of the motor 15 can be extended.
