A power amplifier having a negative feedback circuit for a transmitter and a control method for its phase are arranged as follows. An I-component baseband signal is added to an I-component baseband feedback signal for producing an I-component adding signal. A Q-component baseband signal is added to a Q-component baseband feedback signal for producing a Q-component adding signal. A modulator orthogonally modulates a carrier signal by the I-component adding signal and the Q-component adding signal. An amplifying circuit operates to amplify the quadrature-modulated signal. A demodulating circuit orthogonally demodulates the part of the output of the amplifying circuit and the carrier signal and then outputs the I-component baseband feedback signal and the Q-component baseband feedback signal. Then, the phase of a selected one of the I-component baseband signal and the Q-component baseband signal is compared with the phase of the adding signal corresponding to the selected component baseband signal for detecting if a phase shift exists. If a phase shift exists, the phase of the carrier signal is adjusted so that the phase shift may be made smaller.

Three-dimensional geometric data of an architecture is generated, and image mapping data is generated by mapping a texture representing a pattern on the surface of the generated three-dimensional geometric data. A reflection of a virtual space is generated on the basis of the generated three-dimensional geometric data and image mapping data, and is changed in correspondence with movement of the viewpoint and/or the line of sight of the operator, so that the operator can interactively experience the virtual space of the architecture.

A combined cycle power plant is disclosed, which has a backup function operating during the normal operation as well as when the plant is activated, so as to reliably maintain the steam cooling operation when an abnormal phenomenon occurs. In this power plant, the cool steam of the steam cooling system for cooling a high-temperature portion of the gas turbine is the high-pressure exhaust gas of the high-pressure turbine. When the exhaust gas is unexpectedly insufficient, high or medium-pressure steam output from the exhaust heat recovery boiler is introduced as cool steam into the steam cooling system, thereby reliably continuing the steam cooling operation.

The present invention provides a combined cycle electric power generating plant that effectively reduces the noise produced by the exhaust of steam in the warm-up process or the like. This plant has a duct which drives the steam used for warming a steam cooling system which cools the high temperature parts which are cooled of the gas turbine at the start of the operation to an exhaust duct of the gas turbine. The steam used for warming a steam cooling system is directed to the exhaust duct of the gas turbine, and the noise which is produced by the exhaust of the steam for warming is silenced by the exhaust duct of the gas turbine.

An image processing method and the apparatus thereof for approximating an object shape and reconstructing the corresponding image by subjecting a radial range image to approximating with polygons and reconstructing an image from these polygons execute the following processes. At block B210, reading a radial range image data is executed. At block B220, a plural of different resolution radial range images are generated based upon the read radial range image. At block B230, normal vectors, according to each resolution of a radial range image, are calculated. At block B240, an edge-map having a plural of edges is generated in such a manner that a plural of edges are generated depending upon the resulting normal vectors and the radial range images of different resolutions. At block B250, the edge-maps of all kinds of resolutions are ORed to form a synthesized map. The synthesized map is subjected to correcting crossing and isolated edges. At block B260, each polygon is divided into a plural of triangles. At block B270, assigning 3 dimensional coordinate values and the normal vector generated at block B230 to each apex and the corresponding triangle plane respectively, is executed. At block B280, eliminating unnecessary triangle gaps around a T-shaped point is executed.
