It is an object of this invention to provide a dynamo-electric machine rotor which effectively and uniformly cools a rotor coil outside a rotor core by forming a ventilating groove in the rotor coil, tolerates large field current, and has high reliability. There is provided a dynamo-electric machine rotor in which spaced core slots are formed in a cylindrical rotor core, rotor coilsof stacked turns are fitted into the core slots to form multiple nested rings around a magnetic pole of the rotor, ends of the rotor coils are fixed by an retaining ring, and a spaceris arranged in each of circumferential gaps between the ends of the rotor coils, wherein each spacerhas a length not more than the lengths of linear portionsat the ends of corresponding ones of the rotor coils, a cut-outfor ventilation of coolant gas is formed across at least one of two sides of the spacer, and the spacer is in contact with the rotor coils at the two sides of the spacer at a position located furthest inside in the radial direction of the rotor and an arbitrary position.

A moving object detection apparatus is disclosed and includes a TV camera for capturing images in a monitoring zone. An image changing area is defined within a rectangular region, and is extracted from image signals corresponding to the images captured by the TV camera. From the image changing area, horizontal projective data is obtained. The horizontal projective data is compared with a standard horizontal projective data corresponding to a standard moving object to distinguish the moving object.

Moving object detection apparatus and method

A moving object detecting apparatus is disclosed and includes a TV camera for generating an image signal in accordance with a scene including a moving object and a fixed object. A CPU takes the difference, between the image signals generated by the TV camera at different times to generate a subtracted image signal. CPU then sets a pointing window over the subtracted image corresponding to the subtracted image signal which includes an image corresponding to the moving object. A CPU analyzes signals generated by the TV camera, within the pointing window, and detects an image area corresponding to the moving object.

An area to be monitored is picked up by a TV camera, and data of the picked-up image is converted into digital data in units of frames and stored in frame memories. The image data stored in the frame memories are read out, and a change region is extracted as an image of a moving object. The extracted moving object image has a plurality of dispersed regions including a shadow image. Only the dispersed regions corresponding to the moving object are extracted by setting a frame, and a noise image including the shadow image is removed.

Apparatus for extracting/combining change region in image corresponding

With an audiovisual information presentation system, pictorial image data, drawn on paper sheets in advance and to be optically projected on a screen using an optical projector, is sequentially sensed by a TV camea. Speech corresponding to the image data is input through a microphone. A data storage unit stores the image data and corresponding audio data together with code data for identifying pairs of image and audio data. When a search mode is designated, a desired pair of image and audio data is automatically searched from the data storage unit under the control of a CPU, and is reproduced by electrical monitor display units and a loudspeaker unit independent of image display on the projection screen.
