Title: Step motor driving circuit of analog electronic watch
Inventor: ONO KENICHI
IPC: H02P8/02
Filed: 1979-06-21
Abstract: PURPOSE:To prolong the life of a battery by reducing the through currents of transistors P-Ch and N-Ch by controlling transistors P-Ch and N-Ch for step motor drive by different gates. CONSTITUTION:Once a pulse of waveform beta arrives at terminal beta, the gate voltage of step motor driving P-Ch transistor (TR) TN4 drops slowly as shown by waveform 2-a since the output impedance of N-ChTRTN4 is high in its rise, and the gate voltage of step motor driving N-ChTRTN1 falls quickly as shown by waveform 2-b since the output impedance of N-ChTRTN5 is low. At the fall of the pulse input to terminal beta, the gate voltage of TRTP1 rises rapidly like waveform 2-a since the output impedance of TRTP4 is low and that of TRTN1 rises slowly since the output impedance of TRTP5 is high. Consequently, the through currents of the driving transistors can be reduced to prolong the life of a battery.

Abstract: PURPOSE:To strip scale by forming plural liquid flow passages on the outside peripheral face of a plug body or near said peripheral face and ejecting a part of a press-fed liquid for impressing a working pressure on the tail end face of the plug body to the front of the plug body. CONSTITUTION:The plug body 1 for cleaning is formed of a hard elastic material which is compressible and bendable and the head top 3 thereof is formed to a truncated circular cone shape. The plug body 1 for cleaning inserted in the diametrally constricted state into the pipe P of a pipeline receives the working pressure of the press-fed liquid on the tail end face and travels in the direction A. The scale S in the pipe P is thereby scraped. The press-fed liquid 6 flowing in line grooves 4 changed in the sectional shape by the diametral constriction is partly ejected forward from open ends 5 of the grooves to form ejection flow B which pushes forward the scraped scale S. The scale S is thus efficiently wiped away by the ejection flow B.
