Patent JP-H06338728-A (JP)
Title: High frequency and high efficiency amplification circuit
Inventor: SEKINE KENJI
IPC: H03F1/32
Filed: 1993-05-27
Abstract: PURPOSE:To improve the efficiency by allowing the same frequency component as an input signal to pass through one route and synthesizing a basic wave and a third harmonic of the input signal to input the synthesized wave to an amplifying element after generation of the three-fold wave through the other route and shortening the time, when a voltage and a current exist together, even in the case of a small line forming area of the input signal. CONSTITUTION:The signal having a frequency F1 is distributed to two routes, and one is multiplied by a 3-multiplier 3 to obtain a three-fold wave component, and the other passes a phase shifter 5, and both of them are inputted to a hybrid synthesizing circuit 6. The phase and signal of the signal F1 and the amplitude of the signal F3 are adjusted by the phase shifter 5 and a third harmonic amplifier 4 so that the signal obtained by synthesizing signals F1 and F3 has a square waveform at output terminals of the hybrid synthesizing circuit 6. Since the signal is made more different from a rectangular wave at one output terminal when the signal approximates the rectangular wave at the other of the hybrid synthesizing circuit in this case, a dummy load is provided to absorb the difference. The signal approximated to the square wave is amplified by a high output amplifier 7 and is outputted through a filter which allows only the signal F1 to pass through.

The amplifiers 31, 32 are switched by means of switches 33, 34 under control of control/arithmetic section 23. With such constitution, a high resolution pressure sensor is not required and only a single inexpensive pressure sensor 22 having ordinary resolution is required.

Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To deform and planarize a solder ball array on a substrate by heating solder balls at specified temp. for a fixed time to melt them at a level, then cooling them, and then separating the substrate and a flat plate. SOLUTION: A BGA package composed of a plastic body 1 and substrate 2 is laid without thermally deforming on an insol. flat plate 4 so as to have solder balls 3 directed downward and heated by a heater 5 for a specified time, so that the solder balls 3 dissolve slightly to equalize their heights due to the wt. of the package itself.

Title: Circuit for multiplying frequency of a series of inputted pulses
Inventor: ITO TATSUO
IPC: H03K5/00
Filed: 1988-05-23
Abstract: PURPOSE: To provide an output, of which the frequency is double and the impulse coefficient is in effect 50%, regardless of fluctuations in an input frequency by selecting a reference voltage to be applied to a feedback loop. CONSTITUTION: A ramp signal generating circuit t1 integrates an input pulse P0 and converts it into an output P1 in a triangular waveform. When this output P1 is applied to an exclusive OR gate EXOR, the output of the EXOR is integrated by a resistor RY, capacitor CY and operational amplifier A1 and fed back through a resistor RB to the EXOR. The impulse coefficient of the output from the EXOR is determined by the function of a reference voltage Vz regardless of the frequency of the input pulse P0 . This reference voltage Vz is regulated, so that the impulse coefficient of the output from the EXOR can be in effect 50%. Therefore, when a series of input pulses P0 , of which the frequency is Tin and the impulse coefficient is in effect 50% are applied, series of output pulses of which the frequency is 2Tin and the impulse coefficient is effectively 50% can be provided.
