摘要:
A picture displaying apparatus comprises a storing unit storing a plurality of pictures, a displaying unit displaying the picture, an aimed region designating unit designating a partial region on the picture as an aimed region, an image cutting-out unit cutting-out the aimed region from each of the pictures as an aimed region picture, and a display controlling unit displaying the aimed region picture on the displaying unit. The display controlling unit comprises a superposed picture forming unit superposing a plurality of the aimed region pictures to form a superposed picture, and a visual effect controlling unit displaying each of the aimed region pictures forming the superposed picture at a predetermined transparency on the displaying unit. Even when a specific picture is retrieved in a large amount of pictures in the same or almost the same form, visual retrieval is possible readily and certainly without decreasing the retrieval efficiency.
摘要:
In an interface control semiconductor integrated circuit including a plurality of protocol circuits for processing a protocol such as AV- or PC-oriented protocols engaged in an IEEE 1394 standard-compliant data transmission, power consumption is reduced. To achieve this, the interface control semiconductor integrated circuit including the protocol circuits is provided with a plurality of switches associated with the respective protocol circuits and each of the switches performs a switching between supply and shut-off of a clock. A clock is supplied to one of the protocol circuits which should be used whereas clock to unused protocol circuits are shut-off, by controlling each of the switches.

摘要:
An inter-record alteration detection code verification unit 36 calculates an inter-record alteration detection code by merging a record alteration detection code stored in a record to read from a database 34 and a record alteration detection code in the immediately previous record so as to generate a code and applying a predetermined hash operation to the generated code. The verification unit verifies whether the calculated inter-record alteration code coincides with the inter-record alteration detection code stored in the record to read. If they coincide with each other, data is determined to be not altered.
摘要:
There is disclosed a form document processing apparatus for entry of data described in form documents. The form document processing apparatus includes a main processing section for performing predetermined processing operations for entered form data, and an auxiliary processing section which, upon receipt of a request from the main processing section, performs, in an auxiliary manner, among the processing operations to be performed by the main processing section, a specific processing operation determined by the contents of form data. Therefore, specific processing operations determined by the contents of form data can be performed without a need to develop a program for each type of task.

A vector control system for an induction motor driven by a power converter which generates three phase ac currents containing harmonics. In the system, an exciting current command value and a torque current command value in a rotating magnetic field coordinate system are applied, induction motor primary currents in a stator coordinate system is detected at a period which is the same or integral multiple of that of the harmonic components by integration operation, the detected value of the integrated primary currents is subjected to definite integration over the same time interval as the period thereof thereby detecting fundamental wave components of the primary currents without the harmonic components, the fundamental wave components are transformed in the form of rotating magnetic field coordinate system thereby detecting an exciting current component and a torque current component, a deviation between the exciting current command value and the detected actual exciting current component and a deviation between the torque current command value and the detected actual torque current component are detected respectively, and producing and applying to the power converter three phase ac voltage command values in the stator coordinate system tending to reduce the deviations to zero.

The first and second interpole compensation windings are disposed on the commutation starting side and the commutation ending side of the interpole cores, respectively. The current flowing through the first and second interpole compensation windings are controlled in response to the first and second voltages detected by the first and second brushes disposed on the commutation starting side and the commutation ending side of the brushes.
摘要:
At least one circumferential slot is provided at a predetermined axial position on an armature core so as to cross axial slots receiving a plurality of coil sides of an armature winding and to communicate adjacent axial slots, and the plurality of coil sides to be generally mounted in the same axial slot are partially shifted from one slot to an adjacent one through the circumferential slot so that the coil sides of the armature winding are partially arranged to extend through adjacent slots at a fixed, predetermined circumferential distance. In this manner, the generation of commutating spark is substantially prevented and the commutating performance is improved.
