Title: Production of hydrogen halide and oxygen
Inventor: TANGE KYOICHI
IPC: C01B7/00
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To obtain oxygen and a hydrogen halide without causing a side reaction by allowing water to react with a halogen in the presence of a catalyst made of porous silica having a specified average pore diameter. SOLUTION: Amorphous sodium silicate is fired at about 700 deg.C and immersed in water. The resultant kanemite is put in an aq. soln. of an alkyltrimethylammonium compound as a surfactant, the alkyltrimethylammonium compound is allowed to penetrate between layers of the kanemite by heating and a sheet of the kanemite is bent to form a composite. The surfactant is then removed from the composite and the kanemite is subjected to interlaminar crosslinking by the dehydration condensation of silanol groups to obtain porous silica having 0.7-5 nm average pore diameter as a catalyst. The silica preferably has hydrophilic groups on the surface. Water is allowed to react with a halogen in the presence of the catalyst in accordance with the formula; H2 O+X2 →2HX +1/202 (where X is a halogen).

IPC: G01B11/00
Filed: 1993-10-05
Abstract: PURPOSE: To improve accuracy of measurement resolving power in a sharp territoy by measuring dislocation of an object or change of the position from induction of periodic frequency or the phase number of an interference pattern generated on at least one detector. CONSTITUTION: The quantity and the direction of movement AX are computed by a computer 21, from the striped pattern images on four camera detectors 15, 16, 19, 20. Next, a focus control signal is obtained from the computed value. In this signal, an object 10 to be measured is moved through a focus drive device 22 until a point to be scanned is on the focus 9 of an objective lens 8. For computing the shift, phase values are computed against respective camera pick cells for example by the use of four step evaluation algorithm used in an interferometer. At this time, stripe frequency is directly proportional to induction of the phase value in each stripe period. A derivative is proportional to the movement ▵X value, and the sign of the derivative decides the moving direction.

Title: Semiconductor thin film deposition
Inventor: OSAKA JIRO
IPC: H01L21/203
Filed: 1989-09-26
Abstract: PURPOSE:To increase the surface diffusion distance of III group element in mirror scale for flattening the surface by a method wherein liquid drips comprising more than one kind of III group element are formed on a deposition surface while III and V group elements are fed comforming to specific procedures. CONSTITUTION:The feeding of V group element (As) 1 is stopped and then III group element (Ga) 2 is fed to form liquid drips comprising at least one or more kind of III group element on a III-V group compound semiconductor substrate. Next, the feeding of III group element 3 is stopped and then the V group element 21 is fed for an extremely short time before the feeding is stopped. The V group element 21 is left as it is without feeding the III and V group elements at all for a specific time required for the diffusion of the III group elements 4. Thus, since the V group element is not fed while the III group element 4 is being diffused, the diffusion of III group element 4 is started sliding over the III group element film 22. When the thin film is deposited through these procedures, the diffusion length can be increased by 1-2 figures longer than that in the conventional deposition process so as to assure the flatness in wider range within a short time.
