Title: Charging circuit
Inventor: YAMADA SATOSHI
IPC: H02J7/10
Filed: 1988-12-23
Abstract: PURPOSE:To enable a battery to be fully charged by overlapping the induced voltage of a choke coil with the input voltage from a power source by a bypass driving means during the period the voltage across battery terminals is over the predetermined voltage and by supplying it to the battery. CONSTITUTION:When a battery B is charged and the voltage V0 across terminals is raised so that at the time t1 the voltage V0 across terminals gets higher than the reference voltage Vref, the base voltage of a transistor Q2 shows the same waveform as in a control pulse. When the transistor Q2 is turned ON, the current from the DC power source returns to the DC power source. On the other hand, in the period the transistor Q2 is OFF, the induced voltage of a choke coil L1 is overlapped with the DC input voltage Vi. The charging current is supplied to the battery B from this overlapped voltage through a diode D2.

Abstract: PURPOSE:To determine the optical path difference uniquely by shifting the surface of a reference mirror or an object to be measured such that the optical path difference is varied by an amount corresponding to the associated wavelength and making a decision that the fringe of associated wavelength has zero order when the visibility of interference fringe is maximized. CONSTITUTION:The maximum visibility V' at each measuring point and a value PHI' obtained by adding the movement of a second piezoelectric element 16 to the phase of associated wavelength lambdaeg at that time are stored, respectively, in a maximum visibility register and a highest position phase register. After initializing both registers, the element 16 set the position of reference surface 14 as an initial position in order to determine the visibility V and the associated wavelength phase PHI at each measuring point. The visibility V thus determined is then compared with a visibility V' stored in the register for each measuring point and when V>V', the V' and PHI' are updated to V and 2piN+PHI (N: number of step), respectively. The operation is repeated until the final measuring point is reached while shifting the position of the reference surface 14 by 1../2 at a time. The order of fringe is determined at each discontinuous part separated by a level difference, the profile of each discontinuous part is determined from the PHI', and then the discontinuous parts are combined to obtain the entire profile.
