Title: Dc power supply device
Inventor: NOMURA TOSHIMITSU
IPC: H02M3/155
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To lessen rush current when a power switch is turned on and thereby lessen the current capacity of a battery and prevent the decline in battery life by comparing the output voltage with a reference voltage and causing current to flow in a switching element by the output when it is judged that the output voltage exceeds the reference voltage. SOLUTION: The charging voltage Vc is settled to the battery voltage E when enough time has passed after a power switch 11 is turned on. When the charging voltage VC becomes 50% or above of the supply voltage E, the charging current IC1 begins to decrease and therefore a reference voltage Vref is so set that it may be equal to the voltage obtained by dividing, by a division ratio (n), the capacitor voltage VC at the time when the charging current IC1 decreases to a desired level, that is, the voltage Vref is set to a little lower level than the battery voltage E. Chopper current Is is not allowed to flow in a switching element 22 until the charging voltage VC reaches the reference voltage Vref, and so the charging current IC1 and the chopper current Is are not caused to flow at the same time.

IPC: G01G23/02
Filed: 1984-12-05
Abstract: PURPOSE:To prevent the misweighing by providing an abutment detecting member below an end part of a loading scale at a prescribed interval from the end part and providing a means to inform the abutment when the member abuts on the end part. CONSTITUTION:As shown with the alternate long and short dash line in the figure, if a body M is loaded aside extremely on the left end part of the loading scale 1, the left end part of the loading scale 1 is bent downwards as shown with the alternate long and short dash line in the figure. Although the weight is far smaller than allowable load of a load cell 3, the bending is caused by the large moment force actuated on the loading scale 1. An electric current is flowed into an abutment detecting pin 6a, the loading scale 1, a connecting member 2 and a lamp 7 to light the lamp 7. In this way, a user knows that the proper weighing manner is not performed at then, if the body M is moved to almost the central part of the loading scale 1, the bending is eliminated and the load cell 3 is deformed in proportion to the weight of the body M to output a weight detecting signal.
