Abstract: A window shade is formed of a top rail, a pliable shade body, and a pull cord set. The top rail has an arresting member and two actuating members. The shade body is provided with a plurality of cross pleats, a middle tube, and a bottom tube. The middle tube is provided with a middle cross rod fitted thereinto. The bottom tube is provided with two bottom cross rods fitted thereinto. The shade body can be folded to have an ornamental form by the pull cord set in conjunction with the arresting member and the two actuating members.

Abstract: A fastening device of a top rod of a window shade is formed of a locating seat and a pressing seat. The locating seat has a top plate and a back plate. The top plate is provided with a plurality of through holes, and a cross retaining rib. The back plate is provided with two L-shaped portions, a slide slot, a threaded rod, and a long slot hole. The pressing seat has a position confining plate which is provided with an edge retaining rib, a top retaining rib, and a slide frame plate. The slide frame plate is provided with a bolt pillar and a wing portion having a frame slide rib. The structural strength of the fastening device is reinforced by the L-shaped portions of the locating seat, the bolt pillar and the frame slide rib of the pressing seat.

Abstract: A read only memory cell array and method of operation thereof comprises an array of memory transistor cells, a plurality of word lines, a plurality of bit lines, a plurality of select bit lines, a plurality of bank select lines for enabling reading of a selected bank in the array connected to bank select transistors in the bank, a select even line adapted for enabling reading of even cells in a selected bank connected to select even cell transistors in the bank, and a select odd line adapted for enabling reading of odd cells in a selected bank connected to select odd cell transistors in the array.

Abstract: A ROM IC includes an extra bit line. The extra bit line outputs a first binary logic signal when a word line in a no-use area is attempted to be read and a second binary logic signal when a word line in a use area is attempted to be read. The output of the extra bit line overrides the normal output of the ROM when a word line in a no-use area is attempted to be read, so that the output of a read operation in the no-use area is always a predetermined binary value. This predetermined binary output value occurs in spite of the fact that because of a defect the actual logic value of a storage location in the word line to be read in the no-use area is other than a desired value. When a word line in the use area is read, the output of the extra bit line does not override the actual binary value stored in the word line. Using the extra bit line and associated override circuitry, a ROM IC with a few defects in a no-use area may still be used in an application.

Abstract: A cost-effective and manufacturable method for producing ROM integrated circuits with closely-spaced self-aligned conductive lines, on the order of 0.3 micrometers apart, is described. Parallel, conductive semiconductor device structures are formed in a semiconductor substrate. An insulating layer is formed over the semiconductor substrate. A first conductive polysilicon layer is formed over the insulating layer. The first conductive polysilicon layer is patterned to form first polysilicon conductor lines which are parallel to each other, and orthogonal to the parallel, conductive semiconductor device structures. A first silicon oxide layer is formed on and between the first polysilicon conductor lines. The first silicon oxide layer is anisotropically etched to produce sidewall structures on the first polysilicon conductor lines. A second silicon oxide layer is formed on and between the first polysilicon conductor lines.
