Title: Transmitter-receiver for earth station for satellite communication
Inventor: SASAKI KAZUJI
IPC: H04B7/155
Filed: 1992-01-18
Abstract: PURPOSE:To attain quick demodulation by generating an offset voltage in response to a frequency difference between a reference carrier frequency and transmission frequencies different from plural satellite communication base stations to control the frequency of a recovered carrier. CONSTITUTION:A frequency counter 11 counts a frequency of a recovered carrier C in matching with a frequency of a signal (a) outputted from a variable frequency oscillator 9 during the reception of the modulation signal (a). A CPU 13 being a component of a control means calculates a deviation DELTAf between the frequency of the recovered carrier C and a reference carrier frequency and stores the result to a storage means 14 in cross reference with an identification number of a satellite communication base station during reception. When a transmission signal from the same satellite communication base station is received, the CPU 13 outputs in advance the frequency offset DELTAf. Thus, the frequency of the recovered carrier C causes a frequency offset DELTAf with respect to the reference carrier frequency. Thus, the frequency is coincident with the frequency of the modulation signal (a) received again, resulting that quick carrier lock is attained.

Title: Magnetic recording and reproducing device
Inventor: OOTA KAZUHIKO
IPC: G11B20/10
Filed: 1985-01-18
Abstract: PURPOSE:To discriminate accurately between the playback signal of a magnetic head and noise by constituting a magnetic recording and reproducing circuit which prevents a peak which is not an original peak from being detected owing to a saddle. CONSTITUTION:While a signal (d) obtained by removing unnecessary inversion due to the saddle is obtained from the output signal (c) of a comparator 5 by using a low-pass filter 6, a pulse signal (e) which contains unnecessary pulses generated owing to the unnecessary inversion due to the saddle, but maintains the inversion timing of the output signal (c) of the comparator 5 accurately is obtained from the output signal (c) of the comparator 5 to sample to signal (d) with the signal (f) generated by delaying the signal (e). Thus, the signal which has no unnecessary inversion due to the saddle and holds only the inversion by recording information is obtained from the output of the comparator 5, and this signal is converted into read pulses (h) to obtain correct read data pulses. Thus, there is no readout error occurring even in the presence of the saddle.

Filed: 1989-01-17
Abstract: PURPOSE:To extract pictures regardless of their densities by dividing the picture data into plural units and calculating and binarizing the density for each divided unit. CONSTITUTION:A block selection circuit 10 which decides a specific block of the picture data that is presently processed based on the values of an X counter 8 and a Y counter 9, a density memory address output circuit 11, a threshold value memory address output circuit 12 are provided.

Abstract: PURPOSE:To enhance the sensitivity by installing a plurality of lead-in pipes at a certain spacing in a porous member installed in an ionized chamber, and performing formation of each hemi-sphere oozing at the surface of the porous member. CONSTITUTION:Lead-in pipe 8a-8c for injection of specimen liquid into a porous member 11 are installed at the outer from a splitter 15, and the specimen liquid sent to the porous member 11 via these three pipes reaches the surface in the center of the porous member 11 in its portion with passage holes not contacting a cap 12, and the liquid oozes. As the spacing of these lead-in pipes 8a-8c is selected properly, the specimen liquid having oozed at the center of the porous member 11 forms three independent hemi-spheres. In case the lead-in amount has become treble as much due to three pipes, three hemi-spheres are formed on the surface of the porous member, and the total surface area becomes treble to make the sensitivity three times as large also. Thus the sensitivity can be enhanced.
