Abstract: A process for purifying sucrose fatty acid esters included in a reaction mixture formed by a reaction of sucrose and a fatty acid alkyl ester in an organic solvent as reaction medium in the presence of a catalyst, which comprises adjusting the reaction mixture from which a part of the organic solvent as reaction medium may be previously removed and to which water is added to form an aqueous solution, to a neutral pH region, adding a neutral salt and sucrose to the solution to precipitate the sucrose fatty acid ester, filtering off the precipitate, and washing the precipitate with an acidic water. The washed precipitate in the form of slurry is spray-dried to form a dry powder, and the filtrate is contacted with a reverse osmosis membrane to recover sucrose. According to the invention, purifed sucrose fatty acid esters can be obtained from the reaction mixture without using an organic solvent as purification solvent, while sucrose can be recovered in high yield.

Abstract: An apparatus for inspecting an SMT printed circuit board includes an inspection head mounted to an X-Y table, for directed movement above the SMT printed circuit board which is to be inspected. The inspection head is caused to proceed to successive viewing fields along the surface of the SMT printed circuit board, for inspection by a series of cameras disposed within the inspection head together with appropriate lighting which is selected according to the inspection which is to be performed. Prior to soldering, it is determined whether each of the series of components to be placed on the printed circuit board were deposited as scheduled, and whether the deposited components were correctly positioned. Following the soldering procedure, it is again determined whether each component remains present on the board, and in its correct position, and steps are taken to inspect the solder fillets, and to inspect for any solder bridges.

Abstract: A nonvolatile semiconductor memory device having memory cells in which a control gate  (CG)  is stacked on a floating gate  (FG)  through an insulating film. The memory device has redundant memory cells so as to compensate defective memory cells and a transistor to select the redundant memory cells and the redundant memory cells and the transistor to select the redundant memory cells are formed by a nonvolatile memory transistor. The transistor to select the redundant memory cells has a structure in which the upper surface and side walls of a floating gate are covered by a control gate or a structure in which the floating gate and control gate are covered by a light shielding film and an antireflection film formed under the light shielding film. 
     In a nonvolatile semiconductor memory device having memory cells of a structure in which a control gate is stacked on a floating gate through an insulating film, a phospho-­silicate glass film is formed on side walls of the floating gate and the control gate and a silicon nitride film and an arseno-silicate glass film or boro-phospho-silicide glass film are sequentially formed so as to cover the control gate. 
     A method of manufacturing a nonvolatile semiconductor memory device of a structure in which a control gate is stacked on a floating gate through an insulating film, comprises the steps of: forming the floating gate made of a semiconductor layer and the control gate made of a layer containing a refractory metal which is stacked on the floating gate; covering the floating gate and the control gate by a film which prevents a diffusion of metal atoms and transmits oxygen; and forming a semiconductor oxide film on side walls   of at least the floating gate by executing a thermal oxidation.
