Abstract: At the inflation thereof, an airbag (10) has a three-dimensional shape composed of a front face (11), a back face (12), left and right side faces (13L, 13R), a ceiling face (14), and a bottom face (15). The front face (11) and the back face (12) have a trapezoidal shape in which the upper bottom is wider than the lower bottom. The upper edge of the front face (11) is formed to be wider than the upper edge of the back face (12). At a side collision, the airbag (10) inflates between seats (20L, 20R) so that the airbag face opposed to an occupant (P) falls to the occupant side. This can allow, when the occupant (P) moves to the collision side, the shoulder of the occupant to strike the airbag while simultaneously or substantially simultaneously allowing the head to strike the airbag. An airbag can be provided that blocks, at a side collision, the move due to the impact of the side collision of the occupant in the lateral direction.

Abstract: A method implemented in a print job management apparatus for processing print jobs in a multiple-printer print shop environment is described. Each print job specifies job ticket parameters representing printing requirements. Each received job is processed by comparing the printing requirements of the job with capabilities of the printers. If a printer cannot satisfy all printing requirements of the job, it is eliminated as a candidate printer. Then, from all printers that can satisfy all printing requirements of the job, one printer is selected based on a pre-defined priority preference and the job is submitted to the selected printer. The printer priority preference is created by the operator based on cost and other factors. The operator can also select an alternative execution mode where, among all printers that can satisfy all requirements of the job, the one with minimum wait time is selected.

Abstract: The present invention relates to a size-adjusting fastening mechanism for stakes comprising fixed locking grooves and a movable locking convex block, whereby when one of the grooves engages with the convex block, tooth position is loosened and toecap is telescopic upon pulling. When the groove and the convex block are rotated to deflect so as not to engage with each other, tooth position is pressed to lock so as to be irremovable. Such a structure requires that the pull handle be pulled horizontally forwards and backwards. Being secured with rivet punching, the claimed device possesses good stability, is simple in structure, low in cost and easy for operation.

On the other hand, when the validity information read from the CMM indicates that the fail information is valid, the test apparatus updates the fail information stored in the AFM with the new fail information and writes the updated fail information back into the AFM.
