Title: Structure of diverter plate
Inventor: YAMAZAKI SEIICHIRO
IPC: G21B1/00
Filed: 1988-09-07
Abstract: PURPOSE:To keep a higher heat removal performance to intend to keep a safety of a diverter plate by reducing a cross-sectional area of a coolant flow path only for a higher heat flux part at the ricinity of a separatrix in a nuclear fusion reactor. CONSTITUTION:A heat transfer ratio from a cooling pipe to a coolant is increased by placing cooling pipings 3 and 3' which are located at a position close to a separatrix, in a group of pipings 2, and have throttle parts in them, by reducing a cross-sectional area of a flow path and increasing a flowing velocity of the coolant. Moreover, in a region far from the separatrix and with a lower heat flux, a cross-sectional area of a flow path of a cooling pipe is increased and thereby a flow velocity of the coolant is kept under rather low value. In this process, a required heat removal performance can be maintained and therewith a diverter plate 1 at a periphery of the separatrix is prevented from burn-out damage caused by a local heating and a safety of the diverter plate can be firmly maintained.

Title: Ccd linear sensor
Inventor: KUNO YOSHINORI
IPC: H04N5/357
Filed: 1991-09-03
Abstract: PURPOSE:To completely transfer signal charge from a photodetector to a horizontal shift register and to shorten a reading time by altering the width of a region having a different impurity concentration toward a charge transfer direction to provide a potential difference at the intermediate part of a charge storage unit. CONSTITUTION:Baron B of low concentration is, for example, implanted from a channel stop region 1 to the intermediate part of a charge storage unit 4 except a region 16 gradually increased in width W toward a horizontal register 6 on the intermediate part where the reading electric field of each charge storage unit 4 is weak thereby to form an impurity implanted region 17 having different impurity concentration from that of the region 16. The region 16 having a small width W is strongly affected by the influence of the electric field of the region 17 to make its potential shallow, and at the region 16 having a large width W, the potential becomes deep. As a result, an inclined potential is generated at the intermediate part, and a so-called reading electric field intensity is improved. Thus, the charge transfer efficiency or the intermediate part is improved, and hence the reading time can be shortened.
