IPC: G01T1/20
Filed: 1983-04-04
Abstract: PURPOSE:To freely design special sensitivity distribution to X-rays, by providing a sensitivity distributing means for predetermining the sensitivity of a plurality of detectors corresponding to the position thereof. CONSTITUTION:The detector 1 for an X-ray computer tomography apparatus having an opening width A is constituted of scintillator materials 2 formed of a crosstalk preventing agent and adhered by adhesives 3, a membrane 5 integrated therewith through transparent adhesives 4, 6 and a photodiode 6. The membrane 5 is made large in light transmission characteristics in its central part as compared with the end part thereof and the material 2 of its central part is formed as a sensitivity distributing means of which the sensitivity distribution becomes higher than the material 2 of the end part thereof. By this constitution, the design of special sensitivity distribution to X-rays becomes free regardless of the kind of a scintillator. In this case, a similar result is obtained even if sensitivity distribution is electrically performed by applying a different wt. to X-ray detection output.

IPC: C25D13/22
Filed: 1993-03-18
Abstract: PURPOSE:To form a desired film thickness on the whole of an electrodeposition coating film formed on an object to be coated in an electrodeposition cell by lesseening film thickness differences at respective parts of the object to be coated. CONSTITUTION:The electrodeposition cell 11 is arranged under a conveyor 10 continuously transporting the objects to be coated W and electrode plates 21a... are provided in the electrodeposition cell 11. The voltage applied between the object W and an electrodeposition liquid L in the electrodeposition cell 11 is set lower at a carrying-in end side part than downstream side parts in the cell 11. Since low potential difference is applied on the object at the initial time of the electrodeposition coating, the coating film is certainly formed even on the part where coating material is hard to stick and thereafter the coating film is efficiently formed by applying higher voltage thereon.
