IPC: H04M1/00
Filed: 1992-01-29
Abstract: PURPOSE:To expand a dynamic range and to improve a speech quality by providing a transmitter with a frequency compensation circuit and providing a receiver with a reverse frequency compensation circuit which has the reverse characteristic of the frequency compensation circuit. CONSTITUTION:In the transmitter 101, a compressor 106 compresses the signal level of a sound signal from a band pass filter 105 within a prescribed range to output it to a frequency compensation circuit 107. The higher the high frequency level the signal level of the sound signal is enlarged by the circuit 107, all the frequency components of the output of the circuit 107 become almost uniform and S/N after a secret speech circuit constituted by a scramble circuit becomes constant without regard to the frequency. A receiver 102 demodulates a reception sound signal, releases a secret speech and sends the signal to the reverse frequency compensation circuit 11b. A circuit 116 functions in opposition to the circuit 107, returns the frequency characteristic to that before the compensation to restore the sound signal. Thus, the dynamic range can be enlarged and the speech quality can be improved.

Title: Electroless plating catalyst and laminated sheet for additive-process printed circuit board
Inventor: FUKAI HIROYUKI
IPC: H05K3/18
Filed: 1993-02-01
Abstract: PURPOSE:To obtain the catalyst with the falling of an acceptor substance reduced by depositing the substance on the silicon carbide of a diamond crystal structure. CONSTITUTION:The silicon carbide having a diamond crystal structure is reduced in lattice defects since it consists only of a covalent bonds and is physically and chemically stable as there are no unpaired electron on the atom. Accordingly, the falling of the acceptor substance deposited on the silicon carbide is reduced since its carrier is practically insoluble in a roughening soln. The substrate is impregnated with a thermosetting resin varnish mixed with a catalyst and laminated to obtain a laminated sheet for the additive-process printed circuit board. Consequently, the time until the inner wall of a through- hole has been covered with a metallic layer by electroless plating is shortened, the moisture infiltrated from the inner wall of the through-hole is reduced, and the solder heat resistance and the solderability of the through-hole are not deteriorated.

Title: Afc device
Inventor: KUBO KAZUHIKO
IPC: H03J7/02
Filed: 1983-01-31
Abstract: PURPOSE:To supply the same voltage as a voltage in AGC-on mode from a variable voltage source to the AFC terminal of a tuner even when an AGC circuit is off, by connecting the variable voltage source to the AFC output terminal of the AGC circuit. CONSTITUTION:The AFC circuit 1 enters AFC-off mode when a switch 6 is closed. At this time, the AFC voltage to be inputted to the tuner 2 should be the same as the output voltage of the AFC circuit when there is no input in AFC-on mode. Integrated circuits IC of AFC circuits, however, have variance in DC offset, every IC is different in input voltage and a frequency shift is caused with a fixed bias. For this purpose, the output voltage is measured when there is no input in AFC-on mode and the AFC mode is turned off to close a switch 20 associatively, so a variable resistance 231 is adjusted so that the output voltage at this time is equal to said measured value, thus completing a preliminary adjustment. Then, the same voltage is supplied to the tuner 2 in both AFC-on mode and AFC-off mode, so no local oscillation frequency shift is generated.
