Abstract: According to one embodiment, a nonvolatile semiconductor memory device is connectable to a controller. The nonvolatile semiconductor memory device includes a cell array and a control circuit. The cell array includes a plurality of blocks. The control circuit executes program operations for a plurality of pages included in a write destination block of the blocks, in a certain program order. The write destination block is selected by the controller from the blocks. The control circuit is configured to notify a page address corresponding to a next program operation with respect to the write destination block to the controller.

Abstract: A DB interface is provided between each subscriber database, which stores information associated with each goods including an aesthetic/sensuous attribute unique to each subscriber, and a basic DB, which stores support information for supporting goods planning of each subscriber by electronic processing. The DB interface converts the aesthetic/sensuous attribute to data corresponding to a unified classification and a unified evaluation axis of the basic DB so as to cause the basic DB to fetch the information of each subscriber database as part of the support information.

Abstract: A first terminal data processing unit is arranged in an apparel planning division to process first data necessary to plan an apparel goods. A second terminal data processing unit is arranged in a sewing division to process second data necessary to perform a sewing treatment and management of the apparel goods planned by the apparel planning division. A central data processing unit is connected to the first and second terminal data processing units through communication lines, respectively, and is arranged in an information service division to offer the first and second data to the apparel planning division and the sewing division. A database is connected to the central data processing unit to store at least the first and second data.

Abstract: A real image type variable magnification viewfinder optical system comprising, in order from the object side, an objective lens system having positive refractive power and an eyepiece lens system having positive refractive power. The objective lens system comprises, in order from the object side, a first lens unit having negative refractive power, a second lens unit having positive refractive power, a third lens unit having positive refractive power and a fourth lens unit having positive refractive power. The second lens unit and the third lens unit are moved, with the first lens unit kept fixed, for performing variation of magnification and adjustment of diopter. This viewfinder optical system can have a high magnification and a large field angle of emergence at a low magnification position thereof, a variable magnification ratio of 2 or higher and favorably corrected aberrations, and be manufactured at a low cost.

Abstract: A finder optical system including an objective having a positive refractive power, an image erecting optical member for erecting an image formed by the objective, and an eyepiece for allowing observation of the image formed by the objective and erected by the image erecting optical member. The objective consists of a first positive lens component and a second negative lens component, or a single lens having a convex surface on the object side. This finder optical system has a simple composition, a compact external design and a relatively wide field angle.

Abstract: A catalytic converter for removing noxious pollutants from exhaust gases particularly emitted from an automobile internal combustion engine comprises a housing having a pair of longitudinally spaced catalyst containers mounted therein between inlet and outlet. The housing is constituted by a top housing shell and a bottom housing shell positioned one above the other with respective flanges of the top and bottom housing shells joined together. Each of the catalyst containers is similarly constituted by an upper retainer plate and a lower retainer plate positioned one above the other with respective flanges of the upper and lower retainer plates joined together. The overlapped flanges of the upper and lower retainer plates for each catalyst container are sandwiched between the flanges of the top and bottom housing.
