Abstract: An inverting transfer mechanism of a blow molding apparatus for receiving preforms or blow-molded products that are upright or inverted and are transported along a first circular transportation passage, inverting a posture of the preforms or blow-molded products while transporting the preforms or blow-molded products along a second circular transportation passage, and transferring the preforms or blow-molded products to a third circular transportation passage.

Abstract: A blow molding apparatus that includes a preform supplying station for supplying preforms in an upright state, a heating station for heating the preforms to a suitable temperature condition for blow-molding while transporting the preforms, a blow station for blowing the heated preforms to form blow-molded products, and a collection station for collecting the blow-molded products.

Abstract: A mold opening/closing mechanism of a blow molding apparatus in which a plurality of blow-molding molds are transported along a circular transportation passage with a fixed feed pitch, and each blow-molding mold has a pair of molding dies capable of opening and closing in a lateral direction, including a turntable on which a plurality of blow-molding molds are mounted at intervals of a fixed angle; a vertical moving shaft that rises and falls as the turntable rotates; a slider that slides in a direction perpendicular to an opening/closing direction of the blow-molding molds as the vertical moving shaft rises and falls; and a pair of operation arms that convert sliding movement of the slider to opening/closing movement of the blow-molding molds.

Abstract: A first transfer mechanism of a biaxial stretch blow-forming apparatus has sliders that are transported along a circular transportation passage. The sliders slide along a circular guide rail installed on a turntable. Each of the sliders is swung to left and right by a swing arm as the turntable rotates, and a feed pitch of a preform holding groove formed in a holding plate installed at an end of each of the sliders is changed. The feed pitch can be changed by a simple mechanism. Because the holding groove always faces a radial direction, receiving and handing over actions of a preform sent along the circular transportation passage can be reliably performed.

Abstract: In a biaxial stretch blow molding apparatus (10) for wide-mouthed containers, preforms (6) that are in an inverted state are conveyed on a single plane by preform carriers (40) that go around a carrier circuit (30) in the form of a loop, are heated via a heating station (60), and are then transferred via a transfer station (80) to stretch blow molding mold assemblies (72) that go around a circular looped path (71). The molded wide-mouthed containers (1) are taken out of the stretch blow molding mold assemblies (72) along a conveying path on a same plane and collected by a collection station (90). Wide-mouthed containers can be formed continuously and at high speed, which is less wasteful and more economical than the case where wide-mouthed containers that are formed from films.

Abstract: A biaxially stretching blow molding apparatus perform biaxial stretch-molding for a preform into a predetermined shape by transporting a preform carrier supporting the preform along a transporting path extending across a heating portion and a stretch-molding portion, has first and second reversing means for reversing the preform carrier, and first and second transporting paths forming the transporting path. The first reversing means receives the preform carrier transported in up-side-down position along the second transporting path, reverses the received preform carrier into elected position, and transfers the preform carrier thus reversed to the first transporting path. The second reversing means receives the preform carrier transported in elected position along the first transporting path, reverses the received preform carrier into the up-side-down position, and transfers the preform carrier thus reversed to the second transporting path.

Abstract: A digital electronic wristwatch is provided with an alarm which includes a piezoelectric crystal mounted to vibrate a watch element. The piezoelectric crystal is supplied with a pair of signals, each having a peak voltage equal to that of the battery, but one of these signals is inverted, resulting in a peak-to-peak voltage which is higher than that normally available from the batteries located within the wristwatch housing. Such driving substantially increases the sound output of the crystal due to the effective voltage increase. A unique spring contact arrangement is used to connect the piezoelectric crystal to the watch electronics, and to permit easy removal of the piezoelectric crystal for battery replacement or watch repair. In addition, a flexible mounting arrangement increases the sound output from the alarm while providing water and dust protection for the watch.
