    • A two-step process for production of thermoplastic elastomer, which comprises dynamically vulcanizing polypropylene and olefinic rubber in the presence of peroxide (1st step), and dynamically vulcanizing the vulcanized mixture, polypropylene and halogenated butyl rubber in the presence of zinc oxide (2nd step). In another method (a) polyolefin and olefin rubber are dynamically cross-linked in the presence of an organic peroxide and (b) in a separate second operation a dynamically vulcanized blend comprising polyolefin and halogenated butyl rubber is prepared and mixed with (a) to disperse (a) and (b) in one another. The thermoplastic elastomer composition is useful in materials for parts of automobiles.In an example, pp 9 wt. % parts, EPDM 21 wt. % parts, peroxide 0.3 wt. % part and divinylbenzene 0.5 wt. % part were blended and supplied to the first hopper (1) of biaxial extruder as shown in a figure. In the first blending zone (2), temperature and residence time are 200.degree. C. and 60 seconds respectively. And then, to the second hopper (3) of the extruder, pp 50 parts and the vulcanized product (EPDM+chlorinated butyl rubber) 20 parts were supplied and extruded in the heat blending zone (4) above mentioned mixture for 30 seconds of residence time. The physical properties of the composition are MFR: 18, Flex. Mod.: 3,300 (23.degree. C.) and 1,150 (80.degree. C.), Tens. at break: 105, Elong.: 420%, Izod.: No break (room temperature) and 25 (-40.degree. C.) Shore-D: 58, Flow marks: good and paintability: 100/100.

    • A ring-like rib 19 is erected on an inner circumferential edge of an insertion hole 11, which is opened in the scroll casing 1 so that the fan f is inserted therethrough, while a side wall 18 facing the ring-like rib 19 is provided in the bracket 15 blocking the insertion hole 11. A helical groove portion 20 and a protruding portion 21 are formed in one of an outer surface of the side wall 18 and an inner surface of the ring-like rib 19 and in the other thereof, respectively. The bracket 15 is caught in the scroll casing 1 by turning the bracket 15 in a direction opposite to a direction of rotation of said fan f. Further, during the engagement therebetween, a cooling duct 4 is formed.

    • A beam-forming device includes a first target sound blocker 103 and a second target sound blocker 104 that remove a target signal having a correlation mutually from a first sound signal x1 and a second sound signal x2 which are converted by first and second microphones 101 and 102, a phase synchronizer 105 that synchronizes the phases of the first sound signal x1 and the second sound signal x2 and synthesizes these sound signals by using information acquired when the first target sound blocker 103 removes the target signal, and a noise learner 106 that learns a noise component included in an output signal of the phase synchronizer 105 from signals from which the target signal is removed by the first target sound blocker 103 and the second target sound blocker 104.
