Abstract: The present invention is a pick-up style utility vehicle including a front seat, a rear seat and a cargo bed in order from the front side to the rear side, and a screen for partitioning the cargo bed and ride space on the front side of the cargo bed, in which the cargo bed has at least a stationary bottom plate and an expansion bottom plate, and is changeable between an expanded state where the cargo bed is expanded forward to the ride space and a non-expanded state where the cargo bed does not occupy the ride space, and the expansion bottom plate is pivotable on a horizontal shaft in the right and left direction relative to the stationary bottom plate and the screen.

Abstract: The present invention relates to a network system, the network system of the present invention comprises an authorized client terminal which is connected to a network, a server which is connected to the network, and a firewall which is interposed between the server and the network. The client terminal accesses the server by means of a publicly known protocol via a port having a publicly known port number in the firewall. In the case in which the accessing client terminal is authorized, the server downloads program for realizing effective dedicated protocols solely between the client terminal and itself to the client terminal via the port having the publicly known port number. Furthermore, the server access with the client terminal conducts data communication by executing the program and by means of the dedicated protocols, via the network and the port having the publicly known port number.

Abstract: The present invention relates a database access system comprising: a plurality of database servers, each of which accommodates a database; and an application server which is connected to the above-mentioned plurality of database servers. The application server comprises a plurality of local transaction managers, each of which corresponds to each of the databases, and individually processes transactions for updating the corresponding database; and a distributed transaction manager which individually provides commands for database updating to the transaction managers.

Abstract: A key top mounting structure for connecting a key top to an operating lever of, for example, a power window control switch of a vehicle. The key top mounting structure provides a precise switch operating mechanism which can be used in both a push-push type and a push-pull type switch, thereby reducing production costs by providing component parts common to a variety of key top shapes. The key top mounting structure according to the present invention is provided with an operating lever having an opening surrounded by an upper wall and a pivot shaft for attaching the operating member to a switch body, and a key top having an engaging protrusion and a frame member surrounding the engaging protrusion and spaced therefrom by a gap having a predetermined width.

Abstract: Clearance measuring apparatus for measuring the amount of clearance formed between circumferential edges of a component part and a component part assembling portion of a product main body used with a set jig holding the component part. A stationary claw is fixed to the set jig and is arranged to be arranged to be brought into engagement with the edge of the part. A movable claw is mounted to be movable in a clearance measuring direction and is arranged to be brought into engagement with the edge of the assembling portion. A detecting device is provided for detecting the amount of displacement of the movable claw in relation to the stationary claw.
