Abstract: A video game apparatus includes an external ROM. This external ROM is previously memorized with player object data, basic shadow object data and light object data. A direction in which a shadow is thrown is determined according to the player object data and the light object data, to thereby determine a length of each leg of the player object. Based on the length of the leg and the height of the light, a length of the shadow is determined. Based on the height of each leg, a depth of the shadow is determined. A shape of a displaying shadow object is determined from a state of a ground object to which the shadow is thrown.

Abstract: A video game apparatus includes a CPU. The CPU determines straight lines respectively connecting between the player object and a North Pole, target and marker, and determines respective directions of a direction pointing mark, target pointing mark and marker pointing mark to point direction parallel to the straight lines. The player object or other objects are combined with these pointing marks, and displayed on a display.

The developing roller, supply roller, and conveying fin for each developing unit are angularly arranged in a particular manner.

Abstract: A developing unit of the present invention includes a case which accommodates toner containing pigment, a developing roller, a supply roller having chamfered ends and formed of an elastic member arranged to be pressed against a surface of the developing roller in such a manner as to supply toner to the surface of the developing roller. Also a first sealing member is disposed on the side ends faces of the developing roller and supply roller so as to prevent leakage to the outside portion of the case. Further, a second sealing member in the form of a film is pressed against a lower surface of the developing roller in order to prevent leakage of toner, wherein a quantity &dgr; of displacement of the sealing member due to its abutment against the developing roller satisfies 0.1 mm<&dgr;<0.8 mm, and the thickness t of the second sealing member satisfies 50 &mgr;m<t<500 &mgr;m.

Abstract: A video game apparatus includes an RCP. The RCP performs a conversion process on image data to display a player object or non-player object according to image data transferred from an external ROM to a RAM, and supplies the image signal through the display. The RCP detects whether or not there exists a non-player object at around the player object on the display in response to an operation of a Z button. If a non-player object is detected, the RCP selects the non-player object as an attention non-player object. At this time, the hypothetical camera is changed in position and photographing direction such that photographing can be made for the player object directly facing the non-player object.

Abstract: A developing unit of the present invention includes a case which accommodates toner containing pigment, a developing roller, and a supply roller formed of an elastic material arranged to be pressed against a surface of the developing roller in such a manner as to supply toner to the surface of the developing roller. A sealing member is disposed on the side ends of the developing roller and supply roller so as to prevent leakage to the outside portion of the case. A blade at least longer than the developing roller restrains the quantity of toner on the developing roller. The blade has a radius of curvature between 30 .mu.m and 150 .mu.m.

Abstract: A three-dimensional pattern editing apparatus used in a CAD system edits three-dimensional patterns in accordance with a user's input operation and displays the result of edition. A pattern display unit displays a plurality of three-dimensional patterns, divided into a plurality of areas, on the display device and each having the same pattern, but having different view points. A displayed pattern moving unit moves the three-dimensional pattern which is displayed on any one divided area in accordance with a predetermined input operation; A displayed pattern linking unit moves the three-dimensional pattern displayed on another are to the converted direction in accordance with on the converted amount. The real time display of pattern movement is realized by applying only a logic operation on pixel image data stored in the frame buffer rather than using the vector description of the object.

Abstract: An apparatus for detecting the number of beats in that second time measuring means starts to measure time from a time point when the level of a predetermined frequency component of an input audio signal is once higher than a predetermined level and, after a predetermined period T1 elapses from the time point, the measurement of time by the second time measuring means is terminated at a time point when the level of the predetermined frequency component of the input audio signal is again higher than the predetermined level, thereby to convert a measured period T2 at termination of measuring of the second time measuring means into BPM i.e., the number of beats per predetermined unit time regarding as a unit beat.

Abstract: An optical disc reproducing apparatus repeatedly reproduces information recorded on an optical disc over a desired repeated reproduction interval from a starting position to an ending position. The apparatus is provided with: an optical pickup; a reproducing unit; a moving unit for moving the optical pickup from the ending position back to a predetermined position, which is positioned at a vicinity of the starting position, in a repeated reproduction operation; and a first memory for storing the information, which is recorded from the starting position to the predetermined position. The predetermined position is predetermined such that the information stored in the first memory have an information amount corresponding to a time enough for the moving unit to move the optical pickup from the ending position back to the predetermined position.

Abstract: An apparatus and method for rotating a perspective view of a three-dimensional object image displayed on a display screen from an original view point to a desired view point, and for moving the perspective view in a parallel manner from the original view point to the desired view point. When the perspective view is rotated, a circle is generated that has a first point corresponding to the desired view point. A line segment is generated from the first point to the center of the circle. A hemisphere is generated that has a top surface, a vertex, and the circle as a bottom surface. A second point on the top surface represents the first point projected to the top surface. The desired view point is a projection from the second point to the bottom surface of the hemisphere and the original view point is a projection from the vertex of the hemisphere. The perspective view displayed on the display screen is then changed to the desired view point.

Abstract: A subcode graphics reproduction control apparatus which can automatically execute fade operations between ordinary video images and graphics images. A memory for storing graphics data presenting particular images and transparency data defining transparency of the particular images is provided, the graphics data is read out in a subcode signal format from the memory according to a fade command and sent to a decoder, and with this operation a graphics video signal is generated. Also, the transparency data is read out from the memory according to a fade command, the transparency data value is gradually changed from a specified value in one direction, and a video signal input from outside and the graphics video signal output from the decoder are mixed at a mixing ratio corresponding to the transparency data.
