Title: Alignment stage
Inventor: YAMAMOTO MASAAKI
IPC: G12B5/00
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To stably support a moving stage without being slipped out from a base even when the moving stage is vertically arranged. SOLUTION: A connecting part 3 for connecting a moving stage 2 to a base 1 is formed of a rotating shaft 6 for supporting the moving stage in such a manner as to be two-dimensionally rotatable, and a cross orthogonal, guide 7 for connecting the rotating shaft 6 to the base 1. The rotating shaft 6 has a lock member 10 so that a shaft body 8 is not separated from a bearing 9. The cross orthogonal guide 7 is constituted in such a manner that a first rail 11 and a second rail 12 are slid only in mutually orthogonal directions through a rail support body 13, and both the rails are never moved other than the sliding directions. The first rail 11 is fixed to the shaft body 8 through a connecting member 14, and the second rail 12 is fixed to the base 1.  Thus, even when the moving stage 2 is vertically arranged, the moving stage 2 is supported in such a manner as to be two-dimensionally movable in the in-plane direction of the stage surface in the state where the Z-directional movement to the base 1 is prohibited.

Title: Thin-film transistor and its manufacture
Inventor: TANABE HIROSHI
IPC: H01L29/786
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent a gate leakage which is caused by the step at the end part of an island and to prevent the disconnection of an interconnection in a thin-film transistor which is formed at a low temperature. SOLUTION: A first insulating film 5 arranged at the upper part of a silicon layer which comprises a drain region 3, a source region 4 and a channel region 2 and which is formed to be an island on a substrate is made smaller than the silicon layer. Thereby, the steepness at the edge end part of the island is relieved, and the coverage of a second gate insulating film 6 is enhanced. Thereby, it is possible to largely reduce the probability of causing a gate leakage. In addition, since the film thickness of a peripheral part is smaller than the film thickness at the upper part in the central part of the channel, it is possible to reduce a probability that the disconnection of an upper-part gate interconnection.  In addition, when the permittivity of the second gate insulating film is made large, a field effect which is equivalent to that in conventional cases is obtained even when its film thickness is made larger, and a process yield can be enhanced.

Title: Direct-current damping of induction motor by use of inverter
Inventor: FUJITA MINORU
IPC: H02P3/24
Filed: 1990-02-28
Abstract: PURPOSE:To avoid the phenomenon of reverse rotation of a rotor near a state of stoppage by a method wherein a pulse-shaped output direct-current voltage of an inverter for driving an induction motor is subjected to a step-down control in accordance with the number of revolutions of a rotating system of the induction motor at the time of damping of the rotating system. CONSTITUTION:When a direct-current impression voltage is changed over in two stages from a high voltage to a low one in accordance with the number of revolutions in direct-current damping, the number N of revolutions is lowered by the direct-current damping in conformity with a damping torque curve L1h at a direct-current impression voltage Va11. When the number Ns of revolutions is reached at the time ts, a change-over is made to a voltage Va12 lower than the voltage Va11, and the direct-current braking in conformity with a braking torque curve L1n is conducted till stoppage. Accordingly, the phenomenon of reverse rotation of a rotor can be avoided. In the case when the number N of revolutions at the time point of start of the direct-current damping is prescribed and a time required for the number of revolutions to lower to the number Ns of revolutions can always be estimated, the change-over of the direct-current impression voltage can be made at the time ts. Besides, a control is executed by CPU of a control circuit of an inverter with the detected number of revolutions or the time elapsed used as parameters.

Title: Apparatus for discharge in gas
Inventor: MURATA TAKAAKI
IPC: C01B13/11
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To improve the discharging efficiency and prolong the product life by using a structure to enable the shortening of a discharging gap between plural linear conductive electrodes. SOLUTION: A creeping discharge takes place between linear conductive electrodes 2 by introducing a discharge gas into a flow channel 7 and electrifying the conductive electrodes 2 with an AC power source 6. Since the linear conductive electrode 2 has a dielectric material 3 extending in the direction of height, the electric field from the linear conductive electrode 2 is extended in the direction of height to get a definitely good electric field distribution compared with conventional apparatus. In other word, the applied voltage can be lowered and the reliability of the dielectric material 3 to electric field can be improved by the increase of the surface electric field of the substrate 1 to facilitate the start of electric discharge. Since the surface of the linear conductive electrode 2 is covered with the dielectric material 3, the sputtering degradation caused by the ion bombardment during the discharge in gas can be prevented to enable a stable operation.
