Abstract: An electromagnetic drive type actuator comprises a movable plate having a flat surface, a support positioned around the movable plate, an elastic member connecting the movable plate with the support, wirings extending through the support, the movable plate and the elastic member, and a magnetic field generator. The elastic member is elastically deformable and supports the movable plate so as to allow the movable plate to move in directions parallel to the flat surface of the movable plate. The wirings pass currents. The magnetic field generator generates a magnetic field in a space around the movable plate. The magnetic field has a direction orthogonal to the flat surface of the movable plate. The movable plate is moved in the directions parallel to the flat surface of the movable plate by an interaction between the currents flowing through the wirings and the magnetic field generated by magnetic field generator.

Abstract: In order to compensate for deterioration in gain caused by decreases in signal source impedance on a higher frequency region, a frequency characteristic compensating inductor is inserted between a light-receiving device and its bias power supply. The light-receiving device is connected to the bias power supply by way of the inductor. By causing the resonance frequency determined by the inductor and the parasitic capacitance and junction capacitance of device to coincide in the vicinity of the upper limit frequency of the band of the optical receiver, the equivalent signal source impedance of the light-receiving device can be enhanced, thus compensating for the decrease in gain of the receiver.

Abstract: When a video input (image data) sequentially fetched from a monitor camera is to be stored in data storage means, frame rate calculating means calculates a frame rate for storage of the image data by using a picture recording time mode, a residual capacity of the data storage means, the presence of generation of an alarm signal and a value of a picture quality parameter for data compression. The frame rate calculating means thins a video signal which does not correspond to the frame rate so as not to be stored in the data storage means. Consequently, image data for a predetermined time are stored in the data storage means.

Abstract: A lock control for each processor is based on a lock variable status set by a lock control apparatus in a secondary cache. The lock control apparatus indexes lock address registers upon receiving one of LOCK, SETLS, and UNLOCK requests. The SETLS request sets the lock variables to a "lock" status in all banks after acquiring a "lock" in one bank. The SETLS request prevents a deadlock in a banked memory system.

Abstract: A lock control for a data processing system providing lock control for each data processing unit in the data processing system. The lock control is carried out based on a state of a lock variable, by a lock request control unit of a cache unit connected to the data processing unit. On receipt of a lock request or unlock request, the lock request control unit indexes a lock address register holding an address of the lock variable and refers to a state of a lock stored in a corresponding lock status register. Various kinds of states are defined as a state of a lock variable to indicate that each lock request control unit is in a lock or unlock state. A symbol ULE indicates the state that no acquisition of a lock in all lock request control units is confirmed. Thus, an acquisition of a lock corresponding to a particular lock request control unit can be done with high speed, without confirming states of lock request control units other than the particular lock request control unit.
