Patent KR-810001336-B1 (KR)
Title: Pressurized water reactor flow arrangement
Inventor: GIBBONS J
IPC: G21C15/00
Filed: 1978-02-25
Granted: 1981-10-14
Abstract: A water cooled nuclear reactor has the flow of water divided into two portions.  The first portion flows from the bottom of the core(12) upwards within the core.  The second quantity is introduced into the upper end of the tubes contg. the control rods(48) and flows downwards in the tubes.  The force needed to lower the control rods in emergencies is reduced.  Diversion of the flow around the core is minimised.  The critical character of the construction to allow the flow for cooling the control rods is diminished.  Orifices are not needed to limit the flow in the control rod channels.  Thermal stresses in bolts are reduced.

Abstract: The solid state image sensor of a charge coupled device  type using the photo accumulation effect of photo diode is manufactured by using the trench structure depositing the  insulating  material at  the picture  element  seperation  region.  The  decrease   of effective width in vertical transmission channel  is  inhibied  by preventing the bird's beak shape generating in time of  forming  a field oxide by local oxidation method. The noise is inhibited by a preventing the leakage current. The packing density is improved by increasing the picture element number using the trench structure.
