Abstract: In a gas-bubble brick of refractory ceramic material, the visual detectability of a worn state is improved. The detectability should be independent of the material of the gas-bubble brick. For this purpose, a gas-permeable distance space 3, which has a different geometrical shape in the direction of wear, extends in the gas-bubble brick. As a result, a different pattern corresponding to the state of wear is visible on the surface of the gas-bubble brick when gas flows through the distance space 3.

Abstract: The fabrication method for P+ +/N/P type photo detector in CCD (Charge Coupled Device) is characterized by the following steps of; (a) forming a photo detector region (3) on the surface of a substrate in P type well (2) by the ion implantation of N type ions, after forming P type well (2) on N type substrate (1) fixed by an active region and a field region, (b) forming LTO + BPSG layer (5) on the whole surface, depositing polysilicon (6) doped with P type to a degree of being lohm-cm (concentration 10), and removing all of polysilicon except polysilicon for obtaining a shallow junction, and annealing it at 900-1150 deg.C for 10-30 mins in order to obtain a shallow P+ region (4) under 0.1μm on the surface of a photo detector region (3) by the diffusion of P type ions doped to a polysilicon (6).
