Abstract: A first phase shift circuit amplifies, when a first signal, a second signal having a phase difference of 90 degrees from the first signal, a third signal having a phase difference of 180 degrees from the first signal, and a fourth signal having a phase difference of 270 degrees from the first signal are output from a 90-degree distributor that distributes an input signal, each of any three signals from among the first signal to the fourth signal. A second phase shift circuit amplifies each of any two signals of any three signals and one signal that is not amplified by the first phase shift circuit from among the first signal to the fourth signal. One or more phase shift circuits of the first phase shift circuit and the second phase shift circuit each include a compensation circuit that compensates for a phase error of the synthesized signal.

Abstract: A phase-variable frequency multiplier includes: a 90-degree divider for dividing an input signal into an I-signal and a Q-signal; an amplitude setting circuit for distributing each of the I-signal and the Q-signal to two paths, setting amplitudes of two of four signals including the two distributed I-signals and the two distributed Q-signals depending on a phase shift amount of the input signal, and outputting as set signals, the four signals including the signals with the set amplitudes; a first mixer for multiplying one of the two I-signals included in the set signals by one of the two Q-signals included in the set signals to generate a first signal having a frequency being twice the frequency of the input signal; a second mixer for multiplying the other of the two I-signals included in the set signals by the other of the two Q-signals included in the set signals to generate a second signal with an amplitude ratio with respect to the first signal, being a tangent or a reciprocal of a tangent of the phase sh

Abstract: An image-displaying apparatus has a displaying device including plural displaying parts with the displaying parts being aligned without any space therebetween along the path of mobile object, a supplying device for supplying to the displaying device an image signal on plural still images constituting motion image, a speed-detecting device for detecting a running speed of the mobile object, and a display-controlling device for controlling the supplying device to display the plural still images, respectively, at their set timing on their set positions of the displaying device based on the running speed of the mobile object detected by the speed-detecting device. The image-displaying apparatus provides the motion image obtained by flashing the still images at a predetermined time interval along a path of the mobile object, thereby allowing a person who is travelling by the mobile object to view the motion image due to the still images.

Abstract: A video image displaying apparatus and video image displaying method, applicable to the supplying, by arranging a plurality of picture displaying devices for instance on the inner walls of a tunnel, of consecutive articulated images by the plurality of picture displaying devices to occupants of a train to provide consecutive articulated images using these still pictures without, for instance, causing trouble to the performance by the driver of the mobile object. Blinking of still pictures at terminal displaying apparatuses is started and ended after waiting for the passage of a prescribed part of the mobile object.

Abstract: A video display apparatus with a plurality of display devices arrayed in a line with a predetermined interval at portions which may be watched by passengers on a moving vehicle, a video signal supplying device for supplying a still picture video signal to the plurality of display devices, and an intermittent display control dence for energizing the plurality of display devices simultaneously and controlling a still picture video signal display time and a video display stop time at such an interval as to obtain a clear picture. A video signal which represents successive motions on the whole of a picture as seen from a moving vehicle is supplied to respective display devices. Since a picture is given by an electrical signal, it is sufficient that the contents of the picture may be changed by rewriting the contents of a video memory. Therefore, any pictures may be displayed, and a plurality of pictures may also be displayed.

Abstract: A continuous motion picture system for operation in conjunction with a vehicle carrying passengers along a running path is disclosed. The system has screen boxes having a screen and a projector for displaying a still picture for a duration of a display period. The screen boxes are serially disposed at intervals of a given distance provided in place along the running path of the vehicle. The system also has a device for supplying picture signals of a sequence of fames, which depict motion when viewed sequentially, to the projectors of the screen boxes such that each of the projectors receives a respective one of the frames of the sequence of frames in correspondence with the serial disposition of the screen boxes. The system further has a sensor for sequentially triggering the screen boxes to individually display the respective one of the frames as a still picture for the display period in correspondence with the vehicle passing the screen boxes.

Abstract: This invention is an animal's intention translational method. This method is, first of all, to receive either of the two or both of informational signals about a voice of the animal such as a baby, pet, and domestic animal that they utter and animals actions. After that, it compares with the received informational signal and the data which are analysed by the animal behavioralism before hand, and it selects the data. In addition, the received informational signal is indicated what the animal appeals in words or letters that people are able to understand. As for the above mentioned invention, people are able to communication correctly with the animal.
