Inventor: TANAKA YOSHIAKI
IPC: H04B3/06
Filed: 1987-03-16
Abstract: PURPOSE:To apply the titled canceller even to a carrier phase jitter control system including a delay in its control loop by using an output of an adder adding outputs of multipliers as a phase jitter correction signal. CONSTITUTION:The titled jitter is provided with a Fourier coefficient generating means 101, a coefficient correction means 102, a multiplier 103 and an adder 104. That is, the Fourier coefficient generating means 101 applies Fourier transformation to a signal of an extracted phase jitter to generate a Fourier coefficient group, and the coefficient correction means 102 generates adaptively a complex number coefficient group from a signal of residual phase jitter. Moreover, plural multipliers 103 multiply the complex number coefficient group of the coefficient correction means 102 with the Fourier coefficient group of the Fourier coefficient generating means 101, the adder 104 adds outputs of each multiplier 103 to generate a phase jitter correction signal. In case of applying the phase jitter correction in this way, the canceller is applied even to a carrier phase jitter control system whose control includes a decoder having a delay in its decoding.

Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a placing-laying tile mat, by which the bonding fixing force of tile to a base mat made of a synthetic resin is improved and not only the upward peeling of the tile is prevented but also the tile mat is not shorn and peeled simply even when large sideway force works to the tile. SOLUTION: In the placing-laying tile mat, in which a tile 2 is bonded on a base mat 1 made of a synthetic resin by adhesives 3, a recessed section 2a is formed to the rear of the bonding section of the tile 2 while a notched section 1d is formed to the bonding section of the base mat 1, and a stepped section 1e is formed to the internal side face of the notched section 1d. The notched section 1d and the recessed section 2a of a tile rear are filled with adhesives 3 from the rear side of the base mat so as to cover the stepped section 1e and adhesives 3 are cured, and the tile 2 is bonded. Accordingly, the upward peeling of the tile 2 can be prevented because adhesives 3 are engaged with the stepped section 1e from the rear side, and shear peeling can be obviated because adhesives 3 fill the role of a wedge material to sideway force.  A projecting section is formed to the rear of the tile, the housing section of the projecting section and a notched section are shaped continuously to the base mat while the stepped section is formed to the internal side face of the notched section, and adhesives may also be filled from the rear side.

Title: Boosting circuit
Inventor: ASANO MASAMICHI
IPC: H02M3/06
Filed: 1980-05-08
Abstract: PURPOSE:To improve the using voltage efficiency of a boosting circuit by providing two capacitors and forming a circuit for producing a voltage determined by the ratio of the capacitances of the capacitors at an output terminal. CONSTITUTION:When a pin 6 is used as a power source pin during times t1-t2, the voltage of the output terminal O1 of a power source switching circuit 12 is sequentially shifted at its level in synchronism with the output terminal voltage of an inverter 2. Since this voltage is rectified by a transistor 21 and is inputted to the output terminal O1 of the circuit 13, the raised voltage is obtained at the output terminal O1 and the output terminal O2 of the inverter 21. No current is generated at the pin 6 in this period. Since the diode 24 breaks down when the voltage of the output terminal O1 exceeds the breakdown voltage at the time of reverse bias of the diode 24, it can prevent the damage of the respective transistors due to the abnormal high voltages of the respective output terminals O1.
