  • Patent number: 7464030
    Abstract: Each of the M basic vectors in a noise code book 260 is multiplied by a factor ±1 in a sign adder 270 and combined in an adder 280 to create 2M noise signed vectors. The characteristic of the binary Gray code is utilized as follows. A change ?Gu obtained between a noise signed vector based on a signed word i of the binary Gray code and a noise sign vector based on a sign word u adjacent to the sign word i and different from the sign word i only in a predetermined bit position v is used in such a manner that a sign word u? which is next to reverse the bit position v on the Gray code sequence can express a change ?Gu? from the noise signed vector by utilizing the fact that the sign word u? differs from the sign word u only in one bit position w excluding the bit position V. Thus, calculation is simplified, increasing the vector search speed.

  • Patent number: 7393417
    Abstract: On a wafer holding area 50 on the upper surface of a susceptor 22, a wafer W is supported by a wafer support 54 such that a gap with a predetermined distance is formed between the wafer W and a wafer heating surface 52. A projection 58 that decreases the distance of the gap with respect to the wafer W is formed on the wafer heating surface 52. At this time, the heating condition for the wafer W by the susceptor 22 is adjusted by means of the distances of the gaps at the respective portions of the wafer holding area 50. Thus, the uniformity of the planar temperature distribution of the wafer W and that of the thickness distribution of the formed film can be improved.

  • Patent number: 7219522
    Abstract: It is an object of the present invention to provide a novel aluminum tube of an oval cross section that has a wider range of applications and added values. A disk-shaped metal slug (21) is impact-extruded with the use of a die (14) and a punch (13) each having an optimally designed structure to form a metal tube (T) integrally including a mouth, a shoulder and a body of an oval cross section. A hem portion of the oval body of the tube (T) thus formed and hardened by the impact extrusion is once deformed into a circular shape, and then trimmed off by a turning operation.

  • Publication number: 20070072952
    Abstract: A resin composition for a foam is composed of a branched rubbery olefin based soft resin (C) where its gel fraction (a weight percentage of an insoluble content after extraction with xylene boiled at 138° C. for 3 hours) is less than 5%, and a volume ratio of a component which exhibits a mobility of less than 400 microseconds at a T2 (spin-spin relaxation) time by proton (H+) pulse nuclear magnetic resonance is 55 to 95%, obtained by kneading and reacting to thicken an organic peroxide crosslinking type olefin based copolymer rubber (A) and an organic peroxide decomposing type crystalline olefin resin (B). By the use of this resin composition, it is possible to provide foamed articles which can be used for interior parts for automobiles, have high to low foaming magnifications and a recycling property, and are soft and excellent in cushion property, thermal insulating property and in-mold foam molding property.
