Title: X-ray exposure
Inventor: KITAMURA YOSHITAKA
IPC: H01L21/30
Filed: 1986-08-08
Abstract: PURPOSE:To shorten the time for exposure process while increasing the throughput by a method wherein an X-Y stage is continuously shifted stepwise in the direction orthogonal to a rotary axis of a rotating target (V-groove developing direction) while X-ray emitting electrode beams are oscillated synchronizing with the oscillation of stage in every step shifting to correct any fluctuation in an X-ray exposure region. CONSTITUTION:A mask alignment mechanism including an X-Y stage oscillates between an X-ray emitter 40 and itself while the oscillation is detected by pattern detectors 11 and 12 in the X and Y directions. Any deflection amount of electron beams required for correction of the oscillation is processed by a deflection amount processor 13 making reference to the detection signals and then deflectors (a), (b) 17, 18 in the X and Y directions are driven through the intermediary of deflecting amplifiers 15 and 16 according to the results of processing i.e. after specified alignment time elapsed, the electron beams 3 start deflecting to be oscillated synchronizing with the X-Y stage. At this time, a shutter 7 is opened to start exposing. During the time, the X-Y stage is being oscillated but the irradiating direction of X-rays 5 is kept constant to an exposure region by the synchroneous oscillation of electron beams to correct any fluctuation due to the oscillation.

Title: Air blowing device
Inventor: YAMADA TOMIO
IPC: A45D20/12
Filed: 1993-07-27
Abstract: PURPOSE:To reduce the torque of a motor, and make a small-sized lightweight motor usable by providing a reducing mechanism for reducing the rotating speed of a fan to be lower than the rotating speed of a motor rotating shaft. CONSTITUTION:When a motor 7 is rotated, a fan 6 is rotated with a motor rotating shaft 13 as the center. The rotating force of the motor rotating shaft 13 is reduced by an epicyclic gear 15a to be the rotating speed of the motor 6. Since the rotating speed of the fan 6 is smaller than the rotating speed of the motor 7, the torque of the motor 7 is reduced even when the large fan 6 is rotated with the small motor 7, thereby the temperature rise of the motor 7 is suppressed. Consequently, the use of a large heavy motor having a large output is not required, the output of the motor 7 can be lowered, and reduction in size and weight can be attained.
