Abstract: A scintillation camera comprises a gantry (1) having a plurality of detectors (2), and a plurality of sections (3) which are assigned to the respective detectors, and to which a plurality of collimators (5-1, 5-2 and 5-3) are intended to be attached. A carrier (10) simultaneously supports the collimators (5-1, 5-2 and 5-3) to attach them to their attaching-sections (3) respectively, while the carrier (10) simultaneously supports the collimators (5-1, 5-2 and 5-3) which have been attached to their attaching-sections (3), to detach them therefrom. The attaching or detaching of plural collimators (5-1, 5-2 and 5-3) can be simultaneously done by only one carrier (10). Therefore, the time needed to change the collimators (5-1, 5-2 and 5-3) can be decreased and the operation of changing them can be made extremely easier. As the result, the efficiency of changing them can be remarkably enhanced.

Abstract: A fire alarm system is disclosed in which a receiver unit such as a fire control panel or a repeater (T) has zone lines (L,) connected thereto, with various types of fire detectors (DF1,DE2) being connected to the zone line. Supervising power is normally supplied to the zone lines. When the receiver unit receives a fire signal via a zone line from a fire detector, the receiver unit decides from what type of detector the fire signal was transmitted. Types of fire detectors include, for example, a type having as switching means only a mechanical contact for causing said zone line to be in a short-circuited condition, a type having as switching means a switching circuit with a self-­holding function, or a type having a response lamp. In response to the receipt of the fire signal, either no power, or suitably reduced power or reduced constant current for the zone line to which the operated detector transmitting the fire signal is connected is supplied, depending on the type of detector that has operated, to thereby allow a reduction in power consumption.

Abstract: When a plurality of processors share a plurality of tasks and parallelly process the shared tasks, each of these processors outputs bit information for designating a processor in a group to which the processor belongs, when a currently executed task processing has been terminated, and the bit information is stored in a synchronous register (UB0 - UBn; 5) disposed in each of the processors. When it is detected that all of processors in the same group have terminated task processings, each of these processors in the same group are supplied with a synchronization termination signal from the synchronous registers related thereto. Before all of the task processings have been terminated in the same group, any processors in the same group which have already terminated their task processings progress the execution of the next tasks until they access for the first time a data sharing circuit (102) for holding data shared among the processors.

Abstract: An arrangement for routing calls from a source switch to a destination switch in a telecommunications network. If a direct trunk is available between the two switches, that trunk is used. Otherwise, the destination switch is queried to obtain availability data of trunks to that switch from intermediate switches of the network. This availability data is then compared with availability data of trunks from the source switch to the intermediate switches. A route is then selected using an intermediate switch having available trunks from the source switch and to the destination switch. If a route using lightly loaded trunk groups is available, that route is selected in preference to the use of a route using more heavily loaded trunk groups. Advantageously, routing is performed to dynamically optimize selection of a route based on the current state of the network. 
     In order to ensure that different types of services carried over a trunk group receive equitable treatment, a load objective is specified for each type of service. If the actual load for a particular type of service equals or exceeds the load objective, then an available trunk of the trunk group will only be seized if the number of available trunks exceeds a reserve limit, the reserve limit being the sum of the differences between actual load and objective load for services whose actual load is less than the objective load as limited by a reserve limit for each kind of service. To give further protection to selected key services, an available trunk of a group can only be seized for use with a basic service if the number of available trunks exceeds the number being reserved for key services.
