    摘要： In a conventional needle blow nozzle and blow molding apparatus, because a needle portion is formed to have a linear tip, resistance against insertion of the nozzle into a parison is large and only a small-diameter needle blow nozzle can be inserted into the parison. For this reason, it has been difficult to increase an amount of air supplied to the interior of the parison and to shorten the molding cycle. With a needle blow nozzle, an air cooling method and apparatus, a blow molding method and apparatus, and a blow molded product according to the present invention, since a needle portion of the needle blow nozzle is formed into an umbrella-like shape, the tip of the needle portion provides a pointed needle center so that resistance against insertion of the nozzle into a parison is reduced and a large-diameter needle blow nozzle can be employed.

    摘要翻译： 在传统的针吹嘴和吹塑设备中，由于针部形成为具有直线的尖端，因此能够将喷嘴插入型坯中的阻力大，并且只能将小直径的针吹嘴插入型坯中。 因此，难以增加供应到型坯内部的空气量并缩短成型周期。 根据本发明的针状喷嘴，空气冷却方法和设备，吹塑成型方法和设备以及吹塑产品，由于针状喷嘴的针部形成为伞形， 针部的尖端提供尖针中心，使得能够减小将喷嘴插入型坯中的阻力，并且可以使用大直径针吹嘴。

    摘要： An active noise controller includes a duct (2) of a stainless steel having the shape of a pipe and provided with an opening (1) at a first end thereof, and a loudspeaker (3)connected to a second end of the duct (2). The duct (2) is disposed with its opening (1) located at a distance not greater than half the wavelength of a sound produced by a sound source (4) from the sound source (4) so as to face the sound source (4). A sound produced by the vibration of the vibrating member (5) of the loudspeaker (3) travels from the second end of the duct (2) through the duct (2) to the first end of the same, and the sound is radiated toward the sound source (4). The sound radiated through the opening (1) has a frequency substantially equal to that of an unnecessary sound included in the sound produced by the sound source (4), an amplitude substantially equal to that of the unnecessary sound and a phase substantially opposite to that of the unnecessary sound. The acoustic power of the unnecessary sound can be reduced by the sound produced by the loudspeaker (3), propagated through the duct (2) and radiated toward the sound source (4). The active noise controller is capable of achieving three-dimensional sound suppression with out being affected by heat and vibrations.

    摘要： A method of producing a heat exchanger comprising abutting a tube made of an aluminum material and fins made of an aluminum material, applying to the resulting abutments a flux containing zinc halide, and thereafter conducting a reaction soldering in an inert gas atmosphere. The assembled tube and fins applied with the flux may be moved into a position to enhance the formation if zinc deposited by the reaction soldering during the drying step of the flux. The heat exchanger produced by this method has a thick and uniform Zn coating at the joints with good mechanical strength and surface conditions.
