Abstract: A valve timing adjusting device for and engine includes a sprocket configured to rotate by receiving drive power from a driving shaft, a vane rotor fixed to a driven shaft so as to be rotatable relative to the sprocket, a housing that includes an oil chamber housing the vane rotor and is fixed to one end in a thickness direction of the sprocket, a bolt fixing the sprocket to the housing, and a knock pin inserted into a sprocket hole formed in the sprocket at one end thereof and into a housing hole formed in the housing at the other end thereof to restrict relative relation between the sprocket and the housing. The knock pin abuts against an inner wall of the sprocket hole at one end thereof, and abuts against an inner wall of the housing hole at the other end thereof.

Abstract: A method and system for appearance inspection of a core of a heat exchanger provided with fins and tubes, performing averaging and dynamic binarization on the imaging data to extract an image of only a tube, then calculating, with respect to the extracted tube image, a center axis across a long direction of the tube comprised of the center coordinates of the tube width direction, comparing the discovered center axis with a reference value to find the maximum displacement across the long direction of the tube, and judging the tube is a defect when the maximum displacement is greater than a predetermined threshold.

Abstract: A fin inspection method comprising a step of having an imaging device capture an image of the core and inputting into an image processing device the image data for storage, a step of setting a first region in the image data in which an image of the entire core is captured and setting a second region in which an image of at least a portion of all of the tubes is captured so as to identify position information of the tubes, a step of setting a third region for fin detection between adjacent tubes based on the identified position information of the tubes, a step of performing binarization and noise removal in the third region to obtain an image of the fins and identifying from the image of the fins the edge position information of the fins along a long direction of the tubes, and a step of performing statistical processing of the pitch intervals based on the edge position information of the fins and judging fin defects.

Abstract: An injection molding machine using a plurality of metal molds 2 and a plurality of stations S1 to S10, for executing molding by moving the metal molds in rotation and in one direction includes on one of the sides of the metal molds a plurality of heat pipes 5 which are fitted into the molds and one of the ends of which protrudes from the metal mold, and a heat transfer plate 6 so disposed as to cover a projection portion 5a of the heat pipe protruding from the metal mold. Temperature adjustment plates 4 connected to a temperature adjustment machine 4 are disposed on the other station side and while the metal mold is halted at the station, the temperature adjustment plates clamp the heat transfer plate and adjust the temperature of said metal mold.

Abstract: An appearance inspection method and system of a core of a heat exchanger provided with fins and tubes including identifying a region in which an image of a single tube is captured, performing averaging and dynamic binarization of the image data in this region to extract only the image of the tube, dividing this region into a plurality of blocks, finding the smallest rectangle surrounding a tube at each divided block to find a width dimension of the tube, comparing the tube width dimension at each block found with a predetermined threshold value, and judging a part as good when all of the tube width dimensions at the blocks are the predetermined threshold value or less.
