Title: Antenna device
Inventor: SATOU HIDEO
IPC: H01Q19/12
Filed: 1980-06-03
Abstract: PURPOSE:To improve the broad angle radiating characteristics, by constituting a part of all the surfaces of a support as a special shape. CONSTITUTION:In a Cassegrain antenna, the main reflecting mirror side of a support 4, and in a parabola antenna, a part or all of surfaces of a reflecting mirror side of the support 4, is constituted with a plurality of planes 8 which are orthogonal to the planes including the longitudinal direction of the support 4 and the progressing direction of the plane waves 5, and as shown in Fig. (b), the shape of the cross section within an arbitrary plane including said two directions is the same and the surface of the antenna has irregular unevenness consisting of longer side than the wavelength. With the constitution like this, the scattered waves due to the support 4 are represented with the synthesis of reflecting waves 10 by the planes 8 and the diffracted waves by edges 7. Since the planes 8 are orthogonal to the plane including the both of the progressing direction of the plane waves 5 and the longitudinal direction of the support 4 and are constituted with a plurality of planes toward irregular directions, the reflecting waves 10 are scattered and the diffracted waves are almost uniformly scattered to a wide region.

Title: Device for measuring jitter variable of efm signal
Inventor: HACHI YASUO
IPC: G01R29/00
Filed: 1983-04-30
Abstract: PURPOSE:To detect easily jitter by using a PLL circuit which can not follow the fluctuation of a jitter detecting period signal out of plural kinds of period signals constituting a reproducing EFM signal. CONSTITUTION:A reproducing EFM signal is inputted to the PLL circuit through a comparator COMP and a monostable multivibrator MM. The PLL circuit is constituted so as to follow and respond only to an input signal having a longer period than the period of the variation of a jitter variable to be measured. Therefore, a signal including the fluctuation of the phase of the input EFM signal is taken out from the output of a phase comparator PC. An AND circuit AND extracts a specific period signal P3 having a short period, i.e. a signal P3 modulated at its pulse width by the jitter variable, from the signal Pc. The signal Pc is converted into a phase error voltage and then converted into an effective value by an effective value converting circuit EX.

Title: Digital audio system
Inventor: NISHIKAWA AKINARI
IPC: G11B20/10
Filed: 1988-03-31
Abstract: PURPOSE:To shorten the latency time by either reducing a memory capacity of a buffer memory immediately after completing a search operation or moving a write position for writing a digital signal into the buffer memory to the side of a signal output of the buffer memory. CONSTITUTION:The digital signal outputted from a demodulation circuit 1 is jitter-absorbed and data-corrected by a jitter absorbing and data correcting circuit 2 and then data-compensated by a compensation circuit 3 to be outputted as an analog signal via a D/A converter circuit 4. In a buffer area 2a of the jitter absorbing and data correcting circuit 2, an input signal write position is in the middle of the area when a write speed is appropriate, and is moved to the side of a memory area 2b for data correction when the speed is faster, and to the opposite side when the speed is slower, and then upon completion of the search operation, the buffer area 2a is reduced, while the input signal write position is moved to the side of the memory area 2b for data correction. By this method, a time interval between the input signal position and the output signal position of the buffer memory is shortened, thus reducing the latency time from the finishing time of the search operation to the time when an audio output can be obtained.
