A first driving member for front blade that connects a front blade and a second driving member for front blade are rotatably mounted to a shaft 1g, a rear blade driving member that connects a rear blade is rotatably mounted to a shaft, the first driving member follows the second driving member and is rotated by a biasing force of a set spring in a setting operation, and is pressed by the second driving member and rotated in photography. The restraining means has a restraining member that can go in and out of an operation path of the restrained portion of the first driving member. When the present invention is adopted in a single-lens reflex camera, the restraining member can be within the operation path of the restrained portion in the setting operation for photography using an optical finder, and the restraining member can be outside the operation path of the restrained portion in the setting operation for photography using an electronic finder.

A shutter base plate is made of synthetic resin and is configured with one overhang section on the blade-chamber-side surface at one end of an arcuate slot and the other overhang section on the blade-chamber-outside surface. A shock absorbing member made from elastic material is configured with concave portions on the blade-chamber-side surface and three concave portions on the blade-chamber-outside surface. The shock absorbing member is mounted to the shutter base plate in such a way that these concave portions come in contact with the overhang sections, and as is well known, when an exposure operation is completed, the driving pin of a driving member abuts on the shock absorbing member.

摘要:
In a system allowing an application program (client) to call a procedure of another application program (server), when the client requests the server to supply a procedure call syntax, the server writes the procedure call syntax in a link management table. Thereafter, when the client searches the procedure call syntax from the link management table and calls the procedure, the server executes the procedure. Upon request of the procedure call, the server writes the procedure name and argument list specific to the server in the link management record. It is therefore unnecessary to consider the procedure call method when the client makes application programs.

In a computer system for parallelly executing a plurality of tasks by sharing a plurality of resources in a data base of a computer, a use sequence of the resources to be used by each task is inputted to the computer prior to the execution of the tasks. A possibility of deadlock due to sharing of common resources amojng the tasks is checked based on the information on the use sequence, and a deadlock avoidance information table is prepared. When the task issues a start request, the deadlock avoidance information table is referred and the start of the task which has the possibility of the deadlock is delayed.

This invention relates to a semiconductor device having a resistor element of polycrystalline silicon and method of manufacturing the device. The resistor element comprises a first conductive layer made of a first polycrystalline silicon layer and island-like second conductive members made of a second polycrystalline silicon layer and provided on end sections of the first conductive layer respectively. The resistance value of the resistor element is determined by a center section between the end sections of the first conductive layer. Therefore, high resistance value can be obtained by decreasing the thickness of the first conductive layer, or the center section thereof without sacrificing the degree of integration. On the other hand, the contact portions with wiring layers become a large thickness because they are composed of the end sections of the first conductive layer and the island-like second conductive member. Therefore, a good and reliable contact structure can be obtained in the resistor element having high resistance value.
