IPC: H01L27/06
Filed: 1989-06-19
Abstract: PURPOSE:To enable forming a transistor and other elements simultaneously and to simplify the process by selectively implanting impurities by ion implantation into the contact sections and separated other elements region of a semiconductor layer to form said transistor and other elements. CONSTITUTION:Windows 9e, 9b, and 9c corresponding to ohmic contact sections are made open at a time; therefore, only one resist mask is required for forming said windows 9e, 9b, and 9c, simplifying the process and enabling forming a transistor and other elements simultaneously. Ions are implanted not into the elements one by one but into the whole surface in which the windows 9e, 9b, and 9c corresponding to ohmic contact sections and a region 11R for other elements are made; therefore, less frequent ion implantations and mask alignments in said ion implantations than conventional are enough, simplifying the ion implantation process. Thereby a transistor and other elements can be formed easily at the same time and the manufacture process can be simplified.

Title: Method and apparatus for conversion of frequency into time region
Inventor: MAAKU ANSONII JIYOONZU
IPC: H04N7/30
Filed: 1993-06-28
Abstract: PURPOSE: To improve the throughput of two-dimensional inverse discrete cosine transformation(IDCT). CONSTITUTION: After two-dimensional IDCT is reduced to two onedimensional IDCT operations, transforming operations are separately performed on even and odd pixel input words. In a common processing step, a selected input value is directly supplied to an output adder and subtractor and the other input values are multiplied by a cosine value which is shifted by a fixed scale. In a pre- common processing step, the lowest-order odd input words are doubled and, in the common processing step, the words are paired and added before processing. In a post-common processing step, odd result values are formed by multiplying the intermediate values corresponding to the processed odd input words by a factor. High-and low-order outputs are respectively formed by simply subtracting or adding the odd result values from or to even result values.  Preferably, an input value is shifted to the higher-order side by a scale of '2'. The selected bit of the data words of intermediate results is voluntarily adjusted by forcibly setting the bit to '1β or '0'.

Title: Base isolation double floor
Inventor: MIURA KOICHI
IPC: E04F15/024
Filed: 1993-06-03
Abstract: PURPOSE:To facilitate construction work by fixing an elastic leg on a foundation floor surface to connect a panel support plate with an upper section of the elastic leg and fitting an engaging projection and an engaging recessed section to fix a floor panel. CONSTITUTION:A strut 2 is bonded and fixed on a foundation floor surface 1, the height of a panel plate 24 is adjusted to assemble it on the strut 2, and a floor panel 3 is fixed on the panel support plate 24 to construct a double floor. Next, when a body vibrates due to earthquake, a fixed base plate 20 fixed on the foundation floor surface 1 moves horizontally and integrally with the foundation floor surface 1. A movable plate 22 which supports a floor panel 3 which is a double floor moves relatively in the horizontal direction due to elastic deflection to absorb horizontal force of earthquake force. Also, with regard to vibration in the up and down directions, up and down movement which is transmitted to the movable plate 22 is absorbed by elastic expansion and contraction of an elastic plate 25 via a ball 33. Consequently, earthquake force can be reduced.
