Title: Planar array antenna
Inventor: ARAI HIROYUKI
IPC: H01Q21/28
Filed: 1990-09-26
Abstract: PURPOSE:To switch the directivity of this antenna with a simple feeder circuit by combining an inverted F-shaped resonant radiator which is a small-sized thin structive antenna and a 3dB directional coupler instead of an antenna constituted of a monopole antenna and reflecting plate. CONSTITUTION:As for the electromagnetic field radiated from a resonant radiator 4, the z component of the electric field is of concern. The component of the electromagnetic field in the x-y plane has the shape of the figure 8 which has a maximum value and the an about 90 deg. half-value width in the positive- negative direction of the y-axis, and the component in the y-z plane has nearly uniform directivity in the upper section (z>0) of an earth plate. Accordingly, one maximum value of the directivity can be realized in a horizontal plane by means of a + or -90 deg. phase difference, since the intervals between inverted F- shaped resonant radiators 8-1 and 8-3 and between radiators 8-2 and 8-4 can be decided appropriately. Therefore, the directivity of this plane array antenna can be changed in the horizontal plane by switching the input terminals of the input-output terminals 13-1, 13-2, 14-1, and 14-2 of a 3-dB directional coupler.

IPC: G06F3/12
Filed: 1986-10-28
Abstract: PURPOSE:To continue an operation without stopping printing, by providing a means for storing color codes corresponding to colors in which printing is to be performed, a means for printing information in the colors corresponding to the color codes, means for detecting a color in which printing can no longer be performed, and a means for changing over the color for the color thus detected to the color code for other color in which printing can be performed. CONSTITUTION:When printing is not finished in a normal condition, a printing part 11 sends information on the fault to a printing-controlling part 9. The printing- controlling part 9 sets the fault information into an I/O buffer 1, and reports the generation of the fault to a host device. The host device reports color changeover information constituted of a color code for a color in which printing can no longer be performed and a color code for a color to be used as a substitute, to a printer. The color changeover information is sent to a color code changeover part 3 through the I/O buffer 1. Based on the color changeover information, the color code changeover part 3 changes over the color code in a color changeover table corresponding to the color in which printing can no longer be performed to a color code for a substitutive color. Consequently, the operation can be continued based on the same printing information (including color designation) without stopping printing.

Abstract: PURPOSE:To obtain a voice of high quality by representing a driving sound source signal with a semicyclic pulse train whose fluctuations of pitch cycle are limited to a certain extent and determining parameters so that the difference between a synthesized voice waveform and a phase equalized input voice waveform becomes minimum. CONSTITUTION:A phase equalizing analysis part 4 calculates the coefficient of a phase equalizing filter which shifts the phase characteristics of a voice to zero and the reference point of time of the phase equalization and inputs a voice signal to the phase equalizing filter 5 which is controlled with the filter coefficient to find a phase equalized voice signal. Then a sound source parameter analysis part 30 represents the sound source signal with the semicyclic pulse train after the extent of fluctuations of the sound source pitch cycle is limited and determines parameters constituting the sound source signal so that the difference between the phase equalized voice waveform of the input voice and the synthesized voice waveform becomes minimum, thereby driving a linear filter which has voice spectrum envelope characteristics with the sound source signal. Consequently, a voice of high quality can be obtained.
