Title: Tone squelch signal synchronization transmission system
Inventor: TSUJI TETSUO
IPC: H04B7/26
Filed: 1990-04-04
Abstract: PURPOSE:To improve the articulation of a received voice signal by applying amplitude modulation to a tone signal at a subcarrier frequency in a transmission band of a carrier line, sending both side bands, allowing a base station to apply envelope detection and inputting the obtained tone signal to a radio transmitter. CONSTITUTION:A tone signal ft generated in an oscillator 8 is amplitude- modulated by an output fc of an oscillator 9 at an amplitude modulator 10, converted into a double side band transmission amplitude modulation signal and combined with a voice signal whose band is limited via a high pass filter 11 at a low pass filter 1 and the result is inputted to a carrier line 2. A low pass filter 3 of a base station extracts the voice signal and inputs it to a radio transmitter 5, uses a high pass filter 4 to extract fc-ft, fc, fc+ft and a detector 7 demodulates (envelope detection) the tone signal ft and it is inputted to the radio transmitter 5. Thus, the synchronization transmission of the tone signal is attained and the listening sense of the mobile body radio equipment is considerably improved.

IPC: H04W88/02
Filed: 1990-04-04
Abstract: PURPOSE:To improve the quality of speech in an interference area between base stations by applying synchronization transmission to a tone signal and a voice signal from a command station. CONSTITUTION:A frequency converter 2 of a command station applies frequency conversion to a tone signal and a voice signal in a voice band, superimposes a demodulation synchronization carrier in a voice band, sends the result to each base station via a carrier line 6, the base station extracts a synchronization carrier and demodulates the tone signal and the voice signal by using the carrier thereby synchronizing a modulation signal in each base station. Thus, even when a radio wave from two base stations is received among the base stations, the carrier frequency and the momentary frequency shift are synchronized and it is equivalent to receive one radio wave thereby preventing the deterioration in the reception quality.

Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To avoid the cracks of a solder ball part due to thermal stresses caused by a thermal history in a circuit structure body using ball-shaped solder, by securing the expansion and contraction property/flexibility of a solder junction part due to the generation of thermal stresses between the solder ball and a substrate to be connected. SOLUTION: A solder ball 14 on an electrode part 4A of a first circuit substrate 2 and an electrode part 16a of a second circuit substrate 16 are aligned via creamy solder with an epoxy resin particle 20 before flowing to a reflow process. As a result, creamy solder on each electrode part and the solder ball 14 melt. However, since the melting point of the resin particle 20 is higher and the density is small, the particle 20 rises in the solder ball 14 in the melted solder and is integrated in the direction of an electrode part 4A of the first circuit substrate 2. The resin particle 20 is in nearly a spherical shape and the surface is subjected to nickel plating, thus enhancing the adhesive property with the electrode part 4A at the substrate side.
