Title: Method and circuit for correcting phase error in multiplication circuit
Inventor: DOW STEPHEN W
IPC: H03L7/087
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To provide the circuit and method which reduce the phase error in the output terminal of a multiplication circuit. SOLUTION: The phase error is caused when first and second input signals having asymmetrical signal routes are multiplied in a multiplication circuit 41. A second multiplication circuit 42 multiplies in-phase signals and orthogonal phases and generates an output signal, which includes a phase error having the polarity opposite to that of the phase error generated by the first multiplication circuit 41, in an output terminal 49. Signals in output terminals 48 and 49 are added by an addition circuit 43 to generate a third output signal where the phase error is cancelled.

Abstract: PURPOSE:To reduce the surface roughness and shrinkage in a sintered body, at the time of packing iron series powder into a compacting die under no pressure, heating the powder together with the compacting die and executing sintering to obtain a large sized member, by mixing the iron-series powder with Al powder. CONSTITUTION:Iron-series powder is packed into a compacting die under no pressure, is heated together with the compacting die and is sintered, to which copper-series infiltrating material is infiltrated into a powder metallurgical manufactured article. At this time, the iron-series powder is mixed with Al powder and the mixed powder is packed into the compacting die under no pressure. For firmly Sintering the green compact packed under no pressure, fine powder is required to be incorporated into the iron-series powder. The amt. of the Al powder to be mixed is not defined, but 1 to 15wt.% is suitable, and simultaneously with the increase of the amt. to be mixed, the amt. of the sintered body to be shrunken at the time of sintering and infiltrating is linearly reduced. Furthermore, the average grain size of the Al powder is preferably regulated to 1 to 500mu. By this method, the shrinkage of the sintered body in the sintering and infiltrating stage is suppressed without deteriorating the surface roughness, so that the improvement of the dimensional accuracy and the prevention of constrained cracks can be attained.

The time, when the surface of an Si substrate 9 is contacted with the atmosphere including plasma, is adjusted, and the thickness of a surface oxide film is controlled. Then, the shutter 7 is opened, and the thin film of Ta2O5 of the target if formed. The insulating layer, which is formed on an Si substrate, becomes laminated layers of a plasma oxide film, a mixed film of SiO2 and Ta2O5 and a uniform Ta2O5 film. When the thickness of the surface oxide film of the substrate is controlled at 20Angstrom  or less, the composition of the interface between the insulating layer and the substrate can be controlled. Thus the high quality insulating layer is obtained, and the high quality capacitor is obtained.

Title: Ignition device
Inventor: KAWAHARA KAZUNARI
IPC: F23Q3/00
Filed: 1987-04-13
Abstract: PURPOSE:To make the life of the battery of a power source longer by providing an ignition device which performs continuously high voltage electric discharges by a transformer and an oscillation circuit, condenser which is connected in parallel with the ignition device 3, and constant current section which passes electric current to the ignition device and the condenser with the current from a power source being kept constant. CONSTITUTION:The average electric current of electric currents required for the ignition by discharge is substantially equal to the electric current flowing through a resistor r1, and the value I of this current is the one obtained by dividing the voltage which is given by subtracting the voltage VBE between the base eimitters of a transistor Q2 from the voltage VF in the positive direction between diodes D1 and D2 by the resistance value R1 of the resistor r1, I=(2VF-VBE)/R1. If VF and VBE are made not to change much by the applied voltage, the current value I becomes almost constant. Because the ignition device 3 is not ignited with a constant current, it operates by connecting a condenser C in parallel. As described above by providing the ignition device 3 with a constant current section 6 and condenser C, the life of a battery if it is the power source 1 can be made longer even when the voltage of the power source 1 is high by trying not to pass electric current more than necessary.
