One of the second gears is located at one side of and coaxial with one of the first gears and rotates integrally with this first gear and the other of the second gears is located at the other side of and coaxial with the other one of the first gears and rotates integrally with this first gear. One of the third gears rotates integrally with one of the output shafts and meshes with one of the second gears and the other of the third gears rotates integrally with the other of the output shafts and intermeshes with the other of the second gears. The gear pump has two chambers one of which operates as an inlet chamber and the other operates as an outlet chamber in response to the direction of the rotation of the gears.

Abstract: A laser based, noncontacting measurement instrument particularly adapted for the printed circuit board drilling industry is disclosed. The instrument accurately measures drill diameter, runout, and tip position under actual operating conditions. A laser beam is focused in space and the amount of light occluded by the drill bit as the bit is passed through the beam is sensed by a detector. Diameter, runout, and tip position are calculated by measuring the amount of occlusion, monitoring the angular orientation of the rotating drill; and correlating the amount of light occlusion to the angular orientation of the drill. The instrument automatically compensates for dust and debris in the optical path.

Abstract: An image location identification apparatus extracts a first set of control point data for calculating transformation coefficient and a second set of control point data for verifying the transformation coefficient from image data. According to global location data entered with the image data, a map corresponding to the image data is retrieved from the map data base. A first part of the control point data for calculating transformation coefficient is selected from predetermined control points of the map and all permutations of the first part of the control point data are formed. Then, the transformation coefficients are calculated according to the first set of control point data of the image data and each permutation of the first part of the control point data of the map. The transformation coefficients are verified by using the second part of the control point data of the map. Therefore, according to the verification result, the image data matched with the map is displayed automatically and exactly.

Abstract: A method for forming a lubricant coat on a surface of steel slug (7) to be forged and a forging device (1) provided with a lubricant coat forming system (20). The method makes possible the forging of hard to work material, such as stainless steel. Highly durable parts can be manufacured easily. The durability of the metal molds (11-14) of the forging device (1) is increased, thereby decreasing the cost for the manufacture of the parts. In the method, the uniformly thick lubricant coat can be formed easily even on the transformed end surfaces of the material (7) being worked, providing effective lubrication. The lubricant coat forming member (20) can replace the oil lubrication of the related-art forging device of the inline type, in which the cut end surfaces of the material are not lubricated, without modifying the structure of the related-art forging device especially. The forging device (1) of this invention continously forges the material (7), lengthening the interval for replacing metal molds (11-14) and decreasing the cost for the manufacture of the parts.
