IPC: G01N23/04
Filed: 1993-03-25
Abstract: PURPOSE:To decrease a place required for installation by miniaturizing a data detecting part of the non-destructive inspection device. CONSTITUTION:An X-ray tube 2 generates X rays by a high voltage from a high voltage generating device 6, and an examinee M is irradiated therewith. In this case, a detector 3 detects the quantity of transmission X rays for passing through the examinee M, and sends it to a DAS 4.

The transmitting/receiving equipment 5 outputs this signal as a radio wave. A receiving equipment receives the radio wave transmitted from the transmitting/receiving equipment 5 of a scan part, and stores it in a storage device. An image reconstituting device 12 reconstitutes an image, based on projection data stored in the storage device, and sends it to an image processor. The image processor performs various image processings to the image sent from the image reconstituting device 12, based on the operation of an operating part 10 and converts it to a video signal, and displays it on a display device.

Title: Mold for resin molding
Inventor: NAKAMURA SHIZUKATSU
IPC: B29K105/20
Filed: 1986-03-24
Abstract: PURPOSE:To obtain a molding having less voids by setting a blind-alley-shaped main runner branch on the extended part of a main runner having a branched sub runner. CONSTITUTION:A blind-alley-shaped main runner branch is set on the extended part of a main runner, on the middle of which a sub runner 3 branches. The cross-sectional area of the sub runner 3 is set to be smaller than that of the main runner 2 or the branch 6. The resin flow at first mainly goes to the main runner branch 6 having smaller flow resistance and the amount of the resin flowing into the sub runner is relatively small. Because the main runner branch 6 is a blind alley, after the resin is filled there, it flows into the sub runner 3, goes through a gate 4 and then enters into a cavity 5. Resin containing a large amount of voids therefore enters into the main runner branch 6, where the resin cures and the resin part containing less voids therefore enters into the cavity 5.
