  • Patent number: 6181424
    Abstract: A three-dimensional measurement apparatus for measuring three-dimensional information of an object with high speed and high accuracy is disclosed. A laser light is converted to a collimated light, which forms a stripe of light on an object through a projection unit. The projection unit is moved back and forth by a linear motor along the collimated light in a direction perpendicular to the longitudinal direction of the stripe of light. Since the projection unit projects a light stripe of constant width on the object with constant reception of the collimated light, a plurality of stripes of light can be formed on the object by means of simple movement of the projection unit. The area on the object scanned by the plurality of stripes of light is captured by a CCD camera, and three-dimensional information is measured using the light-section method.

  • Patent number: 6148638
    Abstract: In a method for manufacturing a fluorescent lamp, four dual tubes that are previously manufactured are held at a distance in such a manner that the dual tubes can move horizontally. Four portions for connection are simultaneously heated, and two of the dual tubes are simultaneously moved horizontally to form bridge portions to provide tube assemblies. Furthermore, annealing after bridge connection and the connection of tube assemblies with a bridge are performed simultaneously. Thus, a compact fluorescent lamp comprising eight glass tubes that are connected with bridges to form continuous discharge paths can be obtained. According to the manufacturing method, bridge connection can be performed in a small space and with high productivity, and a fluorescent lamp having a good quality with minor variations in the quality of the bridge portions can be provided.

  • Patent number: 5850590
    Abstract: The invention provides a method for making a novel porous sintered material according to an HIP (Hot Isostatic Press) molding technique usually used for the purpose of obtaining defect-free and highly dense powder products. In the method of the invention, a capsule containing a starting powder in a hermetically sealed condition is heated according to a predetermined temperature pattern and is also subjected to hot isostatic pressing while a pressure is arrived at a maximum pressure level substantially in coincidence with commencement of a sintering temperature-applying period in the temperature pattern and is gradually lowered from the maximum pressure level during the sintering temperature-applying period. By the method, excessive densification is suppressed and the resulting sintered material has a required porosity and is provided with pores open to outside in the inside thereof, along with good strength and surface processability.
