Symbol display device for game machine

A symbol display device includes a first rotary disk with a small diameter and a second rotary disk with a large diameter, which rotate independently while overlapping with each other. A driving shaft, which is firmly fixed to the center of the first rotary disk, is penetrating a hole formed at the center of the second rotary disk. A plate-shaped flange is fixed to the second rotary disk so as to fill in the hole. A driving pipe is firmly fixed to the flange, and the driving shaft is rotatably inserted in the driving pipe. A first stepping motor is connected to the rear end of the driving shaft protruding from the driving pipe, to which a large pulley is firmly fixed. A small pulley is fixed to the driving shaft of a second stepping motor. Rotation of the second stepping motor is transmitted to the second rotary disk through a timing belt.

Dynamic services infrastructure for allowing programmatic access to internet and other resources

A dynamic services infrastructure accepts data describing data resources and stores that data in a relational database from which it may be retrieved to handle service requests issued by application programs. The database stores Service Definition data which is initially supplied in the form of XML Service Descriptor documents which are then mapped into the database from which they may be accessed. Each Service Definition includes an input specification which identifies the address of a resource as well as the nature of the input data to be supplied to the resource with the request, and further includes an output specification which describes the nature of the output information which is supplied by the resource in response to the request. The Service Definition further includes information describing the service provider which supplies the resource, test information including fixed input and output values which permit the operability of the resource to be verified, update information which permits the infrastructure to insure that the Service Definition information is kept current, and security information which permits the system to validate users and provide secure encrypted information exchanges. When a client sends a request for services to the infrastructure, obtains the service description for the desired resource from the database, transmits an output information request to the address specified in said the service description, supplying input information meeting the specification contained in said particular service description to said particular resource, and receives and routs output information provided by said particular resource in response to said output information request to the executing application program.

Modularized bionic wall climbing robot

InactiveCN101898357ASimple to build and tear downVariable configurationJointsVehiclesModularityWall climbing
The invention relates to a modularized bionic wall climbing robot. The robot has five degrees of freedom and comprises joint modules and vacuum adsorption modules which are sequentially connected in series, wherein the connection mode is that: a first vacuum adsorption module, a first I-shaped joint module, a first T-shaped joint module, a second T-shaped joint module, a third T-shaped joint module, a second I-shaped joint module and a second vacuum adsorption module are connected in turn; rotating shafts of the three T-shaped joint modules are parallel to one another and perpendicular to the rotating shafts of the I-shaped joint modules at the two ends; and the modules are connected with clamping rings and positioned with four pins at the junctions and the possible relative rotation among the modules can be prevented. The two ends of the robot are symmetric and the head and the tail of the robot are replaceable. The robot has the advantages of easy construction, simple structure, high wall transition capacity and high obstacle-surmounting capacity and capability of climbing on a clean flat wall with inchworm gait, rotary gait, turnover type gait and the like in all directions and can be widely applied to the fields of building industry, nuclear industry, ship building industry and the like.
