摘要： In a conventional multilayer crosshead, only one pressure sensor is disposed in the inlet of the annular passage, preventing monitoring of membrane discontinuities; parison thickness is not constant; as the crosshead body is not cooled and parison temperature is high, a long time is required for cooling during blow molding, preventing the reduction of the molding cycle. A multilayer crosshead according to the present invention includes pressure sensors disposed in at least two positions of the annular passage so that the flow rate is controlled and monitored so as to eliminate the pressure difference between the pressure sensors, and parison temperature is lowered to a greater degree by a cooling jacket with a built-in heater disposed in the crosshead body so that a blow molding cycle is shortened.

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： A magnetic disk pack includes a plurality of coaxially stacked magnetic disks on one of which is formed a servo recording surface for generating a servo positioning signal. The servo tracks on the servo recording surface include an index pattern consisting of missing pairs of dibits on adjacent pairs of odd and even numbered servo tracks. The index is formed at a starting and ending position of the tracks to mark the circumferential position thereof. In the index pattern, at least three non-missing dibit pairs are interposed between adjacent missing dibit pairs. The examples of the index patterns are: 011110, 0111110, 01111110, etc., in which four, five, or six 1s (representing the non-missing dibit pairs) are inserted between two 0s (representing missing dibit pairs). This organization of the index pattern is effective in reducing the adverse effects of the missing dibits in the index pattern upon the radial position signal obtained from the dibits on the servo tracks.
