IPC: F16C35/02
Filed: 1980-04-21
Abstract: PURPOSE: To simplify the construction of the device while unnecessitating a separate support structure used exclusively for backward thrust, by a construction wherein forward and backward thrusts exerted on a main engine can be borne commonly by a thrust bracket through thrust bearings.  
     CONSTITUTION: The forward thrust load applied downwardly to the main engine is borne by the thrust bracket 7 provided at an upper cover through a pad 10.

Title: Position detection device
Inventor: KITANO HIROSHI
IPC: H01L21/30
Filed: 1993-02-18
Abstract: PURPOSE:To detect a position even when the waveform of a signal taken in by image processing is different in number from alignment marks by providing a parameter resetting means for resetting the wave number of a signal. CONSTITUTION:Illumination light from a light source 5 is radiated to an alignment mark formed on a substrate 4 through a half mirror 6 and a prism 7. The reflected light is then taken in CCD 9 through an index mark 8. The reflection light taken in CCD is supplied as an image to a signal processing device 11 through a camera control device 10. A parameter setting means sets in advance the wave number of a signal to be obtained according to the number of marks or its double as a parameter. When the wave number of a signal taken in is other than a value according to the parameter, the parameter resetting means resets the parameter to the number of a signal to be obtained according to the double of the number of marks or the number of marks. And thus, the position of an alignment mark is detected on the basis of the signal.
