Title: Method and device for detecting three-dimensional position
Inventor: KAMIJO TADAHIRO
IPC: G06T7/00
Filed: 1995-01-27
Abstract: PURPOSE: To accurately detect a focusing position even without providing an automatic focusing mechanism by performing a first-order differential filtering to an object image for binary-coding and forming thin lines and then obtaining the total of picture element values on a screen as a feature amount. CONSTITUTION: Light is applied to an object 1 fixed on an x-y-θstage 4 by a lighting device 5 and an image captured by a CCD camera 2 is processed by an image processing device 6 to extract feature amount. Namely, the device 6 performs a first-order differential filtering to the image to extract a contour part and then binaries the image to exclude a prominent and surplus part by the filter. Since the total of the picture element values in an image surface is the feature amount, the size of the image of the object whose image is picked up is affected by the location of an image pick-up position so that the binarized image for reducing the influence is made thin. Then, the total of all picture element values on the screen is obtained as the feature amount.  Then, the position of the camera 2 and the state of the stage 4 are controlled by the feature amount, thus detecting the focusing position with less error.

Abstract: PURPOSE: To prevent deformation of cylinder bore by arranging an exhaust manifold means having a manifold port portion connected to cylinder bore, and arranging a recess portion extending over the whole inner circumference of the manifold port portion, while forming cylinder wall of each cylinder bore with cast. CONSTITUTION: A cast cylinder block 10 has an exhaust manifold means 16 that is integrated with the cylindrical cylinder bores 12, 14. The exhaust manifold means 16 has a common outlet 18 and manifold ports 20, 22 extending to each cylinder. When high temperature exhaust gas flows into, for example, the inner port of the manifold port 22, stress generated by the heat acts at inner cylinder wall 28 and sleeve portion 26. However, as the recess or slit portion 40 arranged in each manifold port 22 reduces thickness of the bridge portion between outer wall and inner cylinder wall 28, bend or twist stress acting at the inner cylinder wall 28 are isolated, therefore, deformation of the cylinder bore can be prevented.
