A method and apparatus for manufacturing pressurized packages capable of obtaining gas displacement pressurized canned goods with high accuracy of internal pressure by atomizing liquid nitrogen, and supplying it together with low temperature vaporized gases to a head space of a can. A spray device assembly (10) for atomizing and spraying the liquid nitrogen is provided in an opening of the bottom of a liquefied gas storage tank (1) formed as a vacuum heat insulating structure. The spray device assembly (10) is constituted such that a valve (2) for controlling the flow rate of liquid nitrogen, a spray nozzle (3), a liquid nitrogen flowpassage (4) extending from the valve (2) to the spray nozzle (3), a nozzle cooling tank (5) for cooling the flowpassage, and a purge device for cutting an outer peripheral portion of a nozzle and an outlet portion off from the air, so as to prevent them from being frosted, are integrally mounted on a spray body 6. The nozzle cooling tank (5) always cools the pipe 13 and the nozzle 3 by liquid nitrogen, and enables supplying of the liquid nitrogen to the nozzle having a temperature gradient to the neighborhood of a boiling point, without boiling and vaporizing it from the tank to the nozzle. The liquid nitrogen supplied while preventing of being vaporized to an orifice inlet of the spray nozzle allows to pass through a nozzle orifice in the liquid state to release into the atmosphere, thereby giving rise to a rapid vaporizing expansion immediately after moving out of the nozzle orifice, so that other liquid nitrogen still in the liquid phase state is atomized.

An open-top type vehicle roof structure is composed of a frame structure having left and right roof openings separated by a longitudinal center beam, and left and right removable roof lids closing the left and right openings and concealing the center beam under the roof surface. Front and rear latch plates are fixed to the underside of each latch plate near the inner end. The center beam is provided with front and rear receiving members each of which is fixed on the top of center beam, and formed with left and right latch holes for receiving the latch plates of the left and right lids. Each of the latch plates may be formed with an upward flange for preventing an undesired release of the lid by engaging with one of downward flanges of one receiving member, or may be formed with a rectangular corner cut for receiving the projecting end of the opposite latch plate.

The present invention is directed to providing a sterile package (1, 1′) integrally housing a contents-pouring device (5, 5′) which has improved contents pourability and tamper evidence. According to the present invention, the sterile package (1, 1′) can be efficiently produced by adopting the following steps of: (1) disposing a parison (27) in a mold (32) for a plastic container main body, (2) blowing sterile air from a nozzle (24) inserted in the parison (27) to blow-mold the plastic container main body, (3) filling the plastic container main body (2) with contents through the nozzle (24) and retracting the nozzle (24), (4) inserting a contents-pouring device (5, 5′) in the parison located above the plastic container main body (2), (5) clamping a mold (31) for a protective case, and (6) forming a protective case (6) with the parison located above the container main body (2).

This invention concerns a rotary electric machine, for example, a synchronous machine having salient rotary magnetic poles, which is equipped with a built-up type rotor. The built-up type rotor consists of a plurality of rotary members, which are coupled in the axial direction into an integral form.In such a built-up type rotor, the rotary members are sometimes displaced with respect to one another in the radial direction by centrifugal forces to which they are subjected during operation (rotation). As a result, the rotational balance of the rotor is lost, which tends to cause oscillations. Therefore, by skillfully exploiting the centrifugal forces which the rotary members undergo during operation (rotation), the radial displacements of the rotary members to one another are suppressed, thereby also serving to suppress the generation of oscillations.
摘要:
A polyester container obtained by stretch-forming a preform of a thermoplastic polyester resin formed by injection forming wherein the central portion of the bottom wall is the remaining part of the gate at the time of injection forming, and is formed relatively thicker than the bottom wall surrounding the central portion, and the central portion of the bottom wall is substantially amorphous, and the bottom wall surrounding the central portion is oriented and crystallized. The container exhibits excellent heat resistance and shock resistance despite a thick portion that is the remaining portion of the injection gate is formed at the center of the bottom portion.

A method of channel selection between a remote and a base for a cordless or wireless communication system includes the steps of creating a history table having channels assigned to columns and intervals assigned to rows, scanning the channels to determine if interference exists, recording the channels having interference for a given interval in the history table and determining which channel has the least amount of interference over a predetermined number of intervals to select the best channel for communications.
