Abstract: The present invention relates to a speaker for a vehicle and an installation structure therefor, and it is an object of the invention to enhance the speaker installation rigidity without impairing the acoustic characteristic of the speaker. The speaker installation structure comprises a speaker unit (1) for holding a speaker body (11) and having a plurality of claws (13) and a panel member (3) having an opening (4) and a plurality of slits (5). For the installation of the speaker unit (1), the plurality of claws (13) are inserted into the plurality of slits (5), respectively, and the speaker unit (1) is rotated in its circumferential direction. The opening (4) is made to be smaller than the diameter of a speaker housing (12) and to have at least three linear portions (41). Each of the slits (5) is formed outside the three linear portions (41) and inside an outer circumference of the speaker housing (12).

Abstract: An access control apparatus, method, and recording medium for storing a program, provides equal input/output (IO) opportunities to auxiliary memory units for all users by attaching priority information for each user to user-entered IO commands. The prioritized IO commands are stored in an IO queue corresponding to a particular one of the auxiliary memory units, and physical IO is performed on each of the auxiliary memory units in the sequence of priority information attached to the prioritized IO commands in each IO queue irrespective of who the entrant users are.

Abstract: A locking device for a connector assembly wherein a completely fitted or locked condition of connectors thereof can be confirmed clearly at a glance by way of an electric circuit. One of the connectors to be fitted with each other by the above locking device is provided with a locking plate for movement between a locking position and a releasing position, a holding element for holding the locking plate at the locking position, and also a means for confirming the connector fitted condition comprising a short-circuiting element and a pair of short-circuiting terminals so as to be connected with each other for assembling electric connection between the short-circuiting terminals.
