Abstract: A head mounted umbrella and a method thereof, which reduces its manufacturing cost and time and is stably held on a user's body without shaking, and which prevents a user's face from getting wet with rain water, and is hung on a hanger, is disclosed. The head mounted umbrella includes a hood part having a front opening, a body covering part manufactured in such a way that a circular basic cloth having a central opening and at least one cut radial portion is prepared, and adjacent radial edges of the basic cloth are coupled to each other to form a skirt shape, and the skirt-shaped cloth is coupled to a lower edge of the hood part, and an annular elastic ring is coupled to an outer peripheral edge of the body covering part by an attaching cloth strip.

Abstract: A method and apparatus for processing pixel rasterization in a 3D rendering processor is disclosed. According to the method and apparatus, the primary depth checking is performed before the performing of the texture mapping, and thus the unnecessary performing of the texture mapping can be removed. Also, the consistency problem can be simply and easily solved using the flag memory, and by performing the depth reading and depth checking twice, the hit rate of the pixel cache memory is heightened. Thus, the method and apparatus is effective in cost, performance, and power consumption.

Abstract: A method for computing maximum traffic capacitance of a base station using a virtual call in the digital mobile communication system in such a way that an operator at operating terminal for Base Station Manager (BSM) inputs call-set-request instructions using the virtual call to maintain and repair the digital mobile communication system so that traffic state is set between mobile stations in the service area of test base station and a vocoder of a Base Station Controller (BSC) to compute maximum traffic capacitance of the test base station. An operator at operation terminal inputs call set information by operator instruction as much as mobile station numbers to be tested to compute maximum traffic capacitance of the base station. The BSM inputs a virtual call-set-request-instruction by means of a virtual call-set-start-flag.

Abstract: A method for storing parity and rebuilding the data contents of two failed disks in an external storage subsystem comprises the steps of: proving a disk array defined as a matrix of (N-1).sup.

Abstract: The present invention discloses a method for removing iodine compounds from acetic acid, in which the iodine compound is removed by using a solid adsorbent in the form of an activated carbon fiber having a large strength, a large bulk density, and a large specific surface, so that the treatment of large amounts should be possible, that the acetic acid should not be contaminated during the extraction of foreign materials from the adsorbent, and that the adsorbent can be repeatedly used by regenerating it. The method includes the steps of: preparing a filter in the usual manner by using an activated carbon fiber as the adsorbent; and making acetic acid containing an iodide pass through the activated carbon fiber filter, whereby the iodide in acetic acid is removed by being adsorbed by the activated carbon fiber filter.
