Title: Mask defect detecting method
Inventor: TO YOICHI
IPC: G01N21/956
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To shorten a detection time by dividing a pattern formed in a mask to be detected into the first detection area and the second detection area and detecting a defect in every divided area with different detection sensitiveness. SOLUTION: In a substrate 10, an active area 12 is formed in the position surrounded by an element separation area consisting of a LOCOS oxide film, and two linear gate patterns 13 are arranged in parallel. The gate pattern 13 in a mask to be detected is divided into the first detection area, which corresponds to an area 13a requiring high dimensional precision and needs highly sensitive detection, and the second detection area, which corresponds to a rough area 13b and needs detection with ordinary sensitiveness. Only the first detection area requiring fine defect detection for high dimensional precision is detected with high sensitiveness, and the second detection area requiring less dimensional precision is detected with sensitiveness lower than that for the first detection area, and as a result, a detection time can be shortened.

Title: Linear motor for swinging
Inventor: SHIMOE OSAMU
IPC: H02K33/18
Filed: 1991-07-30
Abstract: PURPOSE:To obtain a linear motor having a structure in which the load applied to its bearing can be made extremely small and be uniformed in spite of performing no rotation, by adopting the configuration similar to a cylindrical DC motor of a rotational type. CONSTITUTION:In a linear motor, its magnetic field system side is a moving element, and its armature coil side is a stator. The movable field magnet is provided inside a fixed armature by supporting it by a bearing, and a magnet 21 is so placed at the part, where coils 11, 12 are adjoined to each other, as to be opposed with the coils. Coil currents are made to flow in the directions shown by arrows respectively. The magnetic flux of the magnet 21 is generated in the radial direction of the motor. Since the currents flow downward respectively through the parts of the coils 11, 12, which are opposed to the magnet 21, these parts of the coils receive respectively forces clockwise by Fleming's left- hand rule. But, since the armature coils are fixed, by the reaction forces thereof, the magnet 21 receives a force anticlockwise, and to the movable field magnet, a torque is given anticlockwise. Similarly, the movable field magnet is rotated anticlockwise, by other magnets 22, 23, 24 too.

Title: Ophthalmic device
Inventor: NISHIO KOJI
IPC: A61B3/10
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To execute alignment operation in a short time by changing information on an operating distance for giving an examiner at a position just before the operating distance comes into a prescribed range at the time of aligning an eye to be examined and an ophthalmic device. SOLUTION: When a control lever 102 actually stops after the examiner visually recognizes the erasing of the display of a moving direction, it can not be stopped immediately as some period is required for the responding speed of the examiner. Thus, the timing of the erasing the display of the moving direction is set by considering the responding speed of the examiner so that an optical measuring part may be in an auto alignment possible range, namely so that a luminescent point image may be within an auto alignment movable range, when operation is actually stopped. Consequently, when the examiner operate-stops the lever 102 at the time of visually recognizing the erasing of the display of a moving direction, the optical measuring part enters the auto alignment possible range at the time of actually stopping.
