The data processing unit compares a plurality of digital data stored in the first memory area.  As a result of he comparison, when a given number of one or more digital data having the same values are included in the digital data stored in the first memory area, the digital data is produced as output data.  On the other hand, when the digital data having the same values fail to reach the given number, the digital data stored in the second memory area and the latest or newest one of the digital data read out from the A/D converter are compared.  When the difference between the two compared digital data exceeds a given value, the latest digital data is produced as output data.  When, on the other hand, the difference is less than the given value, the data stored in the second memory area is read out and outputted.

Abstract: ABSTRACT           This invention relates to a full charge detection circuit of a battery which can electrically detect the temperature rise occurring at full charge of the battery by using a temperature detection element, and raising an alarm at the full charge or cutting off the power source.  The device enables more accurate detection of full charge of the battery than that obtainable with previously known methods where pre-setting of the charging time could not be made as accurately, because the temperature or voltage at the time of full charge fluctuated depending upon the change in ambient temperature or in the discharge quantity of the battery.  The present invention enables accurate detection of the full charge time, by detecting the temperature difference arising from the temperature rise at the time of full charge, thus preventing either excessive or deficient charging from taking place.

Abstract: Abstract of the Disclosure Segments of a rock bit are secured together by electron-beam welding.  The segments are slightly spaced apart prior to welding by a thin shim of alloying metal such as titanium which improves ductility of the weld and is a strong carbide-former during welding.
