IPC: H01L21/205
Filed: 1985-09-21
Abstract: PURPOSE:To reduce the width of transition region of resistivity produced on the boundary surface between a substrate and an epitaxial layer, by performing epitaxial growth after diffusing phosphorus on a high density boron doped substrate. CONSTITUTION:Phosphorus 2 is diffused on a high density boron doped substrate 1, and an epitaxial layer 3 is grown. In a series of thermal treatments after epitaxial growth, phosphorus which is diffused on the surface of the substrate 1 is diffused in the epitaxial layer 3. If phosphorus is diffused on the substrate in the manner in which its density at the time when it is diffused from the substrate surface to the depth of lambda, coincides with the boron density of the epitaxial layer, phosphorus and boron compensate with each other, and the remaining part is shown as the transition region of resistivity. Thus, the width of transition region of resistivity can be reduced.

Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To obtain the subject zeolite excellent in absorptive performance with a specified silica/alumina molar ratio by aging a mixed gel shown by a specific compositional formula at a specified temperature followed by crystallization. SOLUTION: First, NaOH is added to an aqueous sodium aluminate solution to form a solution A which is then cooled to about <=30 deg.C; while an aqueous sodium silicate solution B is left to cool to about <=30 deg.C. Secondly, the aqueous solution B is added to the aqueous solution A under agitation to effect completion of gelatin while the whole system is kept at about <=30 deg.C, thus forming a mixed gel with the composition formula: 2.4-237Na2 O.Al2 O3 .2.7-2.8SiO2 .120-140 H2 O. Thirdly, the mixed gel is aged at <=35 deg.C for about 24h and then heated to about 85-95 deg.C and kept at that temperature for input 15h or longer to effect completion of the crystallization.  Subsequently, the crystallized product is put to filtration, washed with water or warm water, and then dried at about 90-100 deg.C, thus obtaining the objective low-silica X-type zeolite with the silica/ alumina molar ratio of 2.20-2.40.

Abstract: PROBLEM TO BE SOLVED: To detect deterioration of an ultraviolet phototube in its early stages. SOLUTION: In a state where a flame is present, an ultraviolet phototube 7 is applied with a deterioration judging voltage V2 lower than a normal discharge starting voltage V0 and it is judged that the ultraviolet phototube is deteriorated if a flame present signal is outputted.

Title: Magnetic brush developing device
Inventor: SAWAYAMA NOBORU
IPC: G03G15/09
Filed: 1981-12-28
Abstract: PURPOSE:To prevent the influence of the opposite polarity of an auxiliary magnet, to separate a developer excellently, and to obtain adequate developing functions all the time, by providing a ferromagnetic field adjusting member between the auxiliary magnet and a conveying magnet. CONSTITUTION:When the developer stays near a falling position in a casing 13 and its staying amount increases, it is blocked between a developing roll 2 and a latent image carrier 1 and part of the developer falls from the contacting part between the casing 13 and electrostatic latent image carrier 1. For this purpose, the axial length of the magnetic field adjusting member 6 is set longer than the length of the auxiliary magnet 4 to provide parts where the member 6 does not operate on both sides of the auxiliary magnet 4, and consequently the intensity of the magnetic field on the roll surface at both end parts of the developing roll 2 is made greater than that on the center roll surface to prevent the developer from separating easily at both end parts of the roll; and the tendency that the developer is carried while sticking to the developing roll through rotation by magnetic force is intensified, thereby allowing the developer at both ends of the roll to separate from the developing roll at nearly the same place with that at the roll center part.
