Title: Fault localizer
Inventor: SAITO OKUTO
IPC: G01R31/08
Filed: 1993-10-29
Abstract: PURPOSE:To enhance accuracy in the fault detection by providing a receiver at each electric station and selectively providing a transmitter and a fault locating means. CONSTITUTION:A locating wave delivered from a master unit 61 in an electric station 41 when transmission lines 44, 45 are normal, propagates on the transmission line 44 and arrives at a branch point 46. Since the impedance is not matched at the branch point, a part of the locating wave is reflected and the remainder is transmitted to electric stations 42, 43 where a part of the locating wave is received by receivers 62, 63 while the remainder is reflected thereon and further reflected at the branch point 46 and a part thereof is received at the electric stations 42, 43. The transmitted wave is located by the distance between the transmitting end of the electric station and the receiving electric station and the reflected wave is located by the distance between the transmitting ends of reflecting points and the distance between the receiving ends of reflecting points. Since the receiving waveforms at the electric stations 41-43 vary upon occurrence of fault at point 47, the fault section can be determined based on the transmitted wave received at each electric station and the distance of fault point can be determined based on the waveform received at an electric station in a sound section closest to the fault section.

Then read data read by an image read means 1 are fed to the binarization means 2, in which the data are binarized based on the threshold matrix. The binarized data are fed to a thinning means 5 and in response to a reduction rate of 3/4, one column among four columns each is thinned. That is, data of the 4th and the 8th columns are thinned and the remaining data are fed to a recording means 6, by which the data are printed out onto recording paper.

Abstract: PURPOSE: To allow a player to enjoy a game in a real and highly vivid manner by outputting an image signal of high quality to a display section from a game machine body as analog RGB video signal and/or composite video signal in addition to an RF signal. CONSTITUTION: An image signal of high quality to be outputted from an encoder 35 is outputted as analog RGB video signal through an AMP36 and as image signal for multifunctional display as composite video signal through a mixer circuit 37. When an image signal from the encoder 35 is outputted as analog RGB video signal and composite video signal, it is necessary to output a sound signal separately to a speaker of a display or the like. To achieve this, it is so arranged to let the sound signal from a main processing section 32 be outputted synchronizing the image signal. In this case, the sound signal is allowed to be outputted as stereo signal through a branch circuit 39. This allows a player to enjoy a game in a more real and moreover, vivid manner by combining an image of high quality and a high presence sound.
