Title: Printed wiring board
Inventor: MACHIDA HIDEO
IPC: H05K3/34
Filed: 1987-05-15
Abstract: PURPOSE:To prevent the spot of a flux from generating on the coating surface of solder resist by arranging three or more types of the escape of the flux at predetermined positions of the solder resist coating section. CONSTITUTION:The escape of a flux is formed by providing a recess 8 for a flux reservoir without coating solder resist ink on the upper surface 1a of an insulating substrate 1 simultaneously when a solder resist film 6 is formed by silk printing. A flux absorbing film 10 is buried in the recess 8 to form the escape. Further, a through hole 9 for a flux reservoir is penetrated through the center of the recess 8 to form the escape. The flux coated on the surface 1a is repelled by the operation of the film 6 by the escapes, and fed to the recess 8, or absorbed to the film 10 to prevent the spot from remaining on the upper surface of the film 6.

Abstract: PURPOSE:To enhance the torque of a motor within a range of the prescribed voltage by holding the amplitude of a modulation signal at the constant times of a basic positive arcuate wave, and forming a waveform containing a plurality of harmonics of odd power. CONSTITUTION:With a phase signal theta as an address a modulation signal of the maximum amplitude (1/2)X3<1/2> is read out from a memory 1, and those for three phases are generated.

On the other hand, a carrier generator 5 generates a carrier signal of a triangular wave synchronized with the modulation signal in the frequency of (3+6n) times of the signal of the modulation signal. Comparators 6-8 compare the carrier signal with the modulation signal to generate 3-phase PWM signal, thereby operating an inverter 9. The drive current contains low frequency harmonics, a large torque is generated in a motor 10, and a torque ripple and the copper loss of the harmonics remain low.

Abstract: PURPOSE:To operate an automatic control loop normally at all times by using an output signal of an identifier device while identification is applied with its threshold level deviated and resetting the automatic control loop by the result of detecting the converging state of a demodulation signal. CONSTITUTION:When the converging state of the demodulation signal is deteriorated and a demodulation signal D or E exceeds the threshold level C or B and enters the hatched portion, a level 1 appears at the output of an EX-OR gate 41.
