Abstract: A three input arithmetic logic unit (230) forms a mixed arithmetic and Boolean combination of three multibit input signals. The arithmetic logic unit (230) first forms a Boolean combination and then forms an arithmetic combination. The current instruction drives an instruction decoder (250, 245) that generates the functions signals F0-F7 which control the combination formed. The three input arithmetic logic unit (230) preferably employs a set of bit circuits (400), each forming carry propagate, generate and kill signals. These signals may employed with a multilevel logic tree circuit and a carry input to produce a bit resultant and a carry output to the next bit circuit. This structure permits formation of selected arithmetic, Boolean or mixed arithmetic and Boolean function of the three input signals based upon the current instruction. Selection of the function signals enables the combination to be insensitive to one of the input signals, thus performs a two input function of remaining input signals. The instruction itself may include the function signals and function modification bits, or the function signals and function modification signals may be stored in a special data register. Function modification signals cause modification of the function signals prior to use. The three input arithmetic logic unit (230) includes a least significant bit carry-in generator (246) supplying a carry input to the least significant bit. This carry input is determined by the combination being formed, and generally is "1" only during subtraction. The carry input may be specified in the special purpose data register (D0) for certain instructions. The combination formed is optionally modified dependent upon the sign bit of one of the inputs.

Abstract: In a device isolation method for a semiconductor device, after a pad oxide layer (52) and a nitride layer (54) are formed on a semiconductor substrate (50), the nitride layer located above a device isolation region is removed. An undercut (C) is formed under the nitride layer (54) by partially etching the pad oxide layer (52). After a first oxide layer (56) is formed on the exposed substrate and a polysilicon spacer (58) is formed on the sidewalls of the nitride layer, a void (V) is formed in the oxide layer under the nitride layer which is formed on the active region, by oxidizing the resultant structure in which the polysilicon spacer is formed, at a temperature at or above 950°C. Thus, good cell definition and stable device isolation can be realized, while solving a typical problem of a conventional LOCOS method by forming the void intentionally in the pad oxide layer thickened by bird's beak punch through.

Abstract: A yarn traverse apparatus which prevents adjacent blades from interfering with each other and breaking even if blades of any of traverse mechanisms are out of phase and which allows the traverse mechanisms to be installed and removed easily. The yarn traverse apparatus includes a plurality of traverse mechanisms arranged so as to be adjacent to one another with respect to a plurality of juxtaposed bobbins. Each traverse mechanism has a set of two shafts arranged upstream of a corresponding bobbin. The two shafts are orthogonal to a shaft of the corresponding bobbin and rotate in opposite directions. Each of the two rotating shafts has blades attached thereto, the blades serving to traverse a yarn. Each traverse mechanism is arranged to form two surfaces of rotation when the blades attached to the set of two rotating shafts rotate. The plurality of such traverse mechanisms are arranged so that loci of rotation of the blades belonging to adjacent sets partially intersect. When yarns are traversed by such yarn traverse apparatus, surfaces of rotation formed by the blades attached to the two shafts of rotation of each of the adjacent traverse mechanisms are uniformly as well as sufficiently inclined with respect to a surface formed by a yarn in a single direction as viewed in vertical directions, so that the surfaces of rotation formed by the blades belonging to the adjacent sets will not interfere with each other.

Abstract: This invention pertains to a method for varying the level of an alerting indicator of a radiotelephone while an incoming call is being received, and also to a radiotelephone that operates in accordance with the method. The method includes a first step of operating a user interface (22) for inputting information to a controller (20) of the radiotelephone, the information specifying that an alerting indicator volume be reduced or muted. In response to the inputted information, a second step reduces the alerting indicator volume. An alerting indicator volume that has been reduced is increased upon the termination of the incoming call signal, upon the elapse of a predetermined time period and/or in response to information inputted to the controller (20) via the user interface (22), which information specifies that the alerting indicator volume be increased. In one embodiment of the invention, the alerting indicator volume is maintained at a reduced value until information is input to the controller (20) via operation of the user interface (22), which information specifies that the alerting indicator volume be increased. In response to the inputted information, the alerting indicator volume is increased. The invention may be used in radiotelephones employing non-audio alerting indicator devices for indicating an incoming call, such as vibrating devices.
