Patent JP-H01297592-A (JP)
Title: Level holder
Inventor: HIZUKA TETSUO
IPC: G12B5/00
Filed: 1988-05-26
Abstract: PURPOSE:To automatically maintain the level holding of a table by using superconducting particles which generate a Meissner effect in the temp. environment of liquid nitrogen. CONSTITUTION:A container 6 of a nonmagnetic material is parallel and integrally mounted to the rear surface of the table 5 of a nonmagnetic material to be held level. The superconducting particle groups 8 which generate the Meissner effect in the temp. environment of the liquid nitrogen 7 filled in the container 6 float without contact with a magnet plate 10 for averting the magnetic lines of force of the magnet plate 10 and act to support the table 5 in space. A hollow box 9 move upward of the inclination while expelling the superconducting particle groups 8 in the liquid nitrogen 7 for its buoyancy when the container 6 inclines. The expelled particle groups 8 move in the downward direction of the container 6 and eventually move near to the magnet plate 10. The force to push up the table 5 is then additionally intensified by the effect of the Meissner effect inversely proportional to the square of the distance from the magnet plate 10. The level of the table 5 is thus automatically maintained.

Title: Optical switch
Inventor: ODAGIRI YUICHI
IPC: G02F1/015
Filed: 1986-06-03
Abstract: PURPOSE:To increase an extinction ratio by including a semiconductor laser where only an active layer just under a light charging window is about circular and which is coated with a current block layer, the first optical system which charges the input light beams to the window, and the second optical system which transmits the output light beams from the semiconductor laser. CONSTITUTION:When the input light beams are charged from a light charging window 28 to a semiconductor laser 1 by the first optical system 29, the semiconductor laser 1 is changed from the turning-off state to the turning-on state to perform laser oscillation. The output light beams are transmitted by the second optical system 30. At this time, the charging current of the semiconductor laser 1 is fixed 1mA smaller than a laser oscillation threshold. Though a saturable absorber is formed just under the light charging window 28 because current charging there is completely suppressed by the second current block 16, laser oscillation is easily started by sufficient absorption in a circular active layer 13 due to light charging.

Title: Variable threshold field effect transistor
Inventor: HATTORI ICHIRO
IPC: H01L29/78
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To realize a variable gain differential amplifier which does not generate any distortion in principle or an amplifier which can be adjusted for offset of a CMOS by generating a gate potential gradient in the direction perpendicular to the flowing direction of a drain current by means of the internal resistance and control current of a gate electrode. SOLUTION: When a drain current Id flows in, for example, the vertical direction, gate terminals G1 and G2 are provided at both ends of a gate electrode G extended in the direction perpendicular to the flowing direction of the current Id. Since the internal resistance of the gate electrode G is not zero, a potential gradient can be generated when a current is made to flow to the electrode G after connecting a control current source I to the terminals G1 and G2. Then the threshold voltage of a field effect transistor can be adjusted by adjusting the potential gradient. In other words, when a field effect transistor having such a structure is used, the threshold of the transistor can be controlled by changing the control current I which is made to flow to the gate terminals G1 and G2.
