Title: Step back mechanism
Inventor: TODA TERU
IPC: B23B47/34
Filed: 1984-05-07
Abstract: PURPOSE:To make the time and skill for machining a step back mechanism unnecessary by forming the endless ring shaped cam groove which can increase and decrease the fitting depth of the output side shank for a rotary shaft in the step back mechanism of a drill or the like. CONSTITUTION:When an input side shank 4 is rotated while making a fixing tube 1 remain in non-rotation, an output side shank 6 is rotated together with a rotary shaft joint 3. The rotation is converted to the spin and revolution of the steel balls 14 contacted with a ring shaped concavity 20, 21, and a slide ring 15. And while the retainer 13 for holding the steel balls 14 makes one revolution, the step backing is generated due to the cam work reciprocating between the head set in a cam groove 24 and a large inner diameter portion (a) formed at the inner cylindrical surface 15' of the ring 15 at the output side shaft 6 to make the cutting cool provided on the said shaft 6 separate momentary and slightly from its cutting position for the use of chipping chips. Thus, the time and skill for machining a step back mechanism is made to be unnecessary.

Abstract: PROBLEM TO BE SOLVED: To automatically correct deviation in a position by executing the self- diagnosis of the deviation of the adjusting position of a stereo camera in the state of being assembled into a system. SOLUTION: One pair of a reference image and a comparison image used for deviation detection is picked up by the stereo camera again (S103 and S104) by changing the luminance extracting range of shutter control from a normal whole image to a deviation detection candidate area so that optimum exposure is obtained at the deviation detection candidate area in the case that the dispersion of a luminance changed quantity in the picked-up image of the stereo camera exceeds a lower limit threshold (S101 and S102).  Then, the deviation detection and subpixel interpolation per area are executed by setting the area to calculate a city block distance from the deviation detection candidate area for an image obtained by the affine transformation of the reference image and the comparison image, and a deviation straight line is decided by Hough transformation and the method of least squares (S105-110), and affine transformatin parameter is rewritten by a correction quantity obtained from the deviation of the straight line (S112), so that the deviation of the adjusting position of the stereo camera is automatically corrected in the state of being assembled into the system.

Abstract: PURPOSE:To enhance the reliability to the driving control of an intake/exhaust valve by compensating the conditions of current application to the electromagnet for driving an intake/exhaust valve so as to accord the actual life quantity to the desired lift quantity. CONSTITUTION:The intake valve 1 of an engine 6 is driven to open or close by an electromagnet 3.
