Title: Non-linear dc-dc converter
Inventor: INAO KIYOHARU
IPC: H02M3/155
Filed: 1978-11-16
Abstract: PURPOSE: To obtain a compact converter with linear conversion characteristics wherein an input voltage and an output voltage have the same polarity by connecting a diode between the tap of an inductance element in a smoothing LC circuit and a common line.  
     CONSTITUTION: A converter is constituted by a smoothing circuit comprising a switching element S, an inductance element L, and a capacitor C. A diode D is connected between the tap of the inductance element L and a common line. Since a current caused by the induction voltage of the inductance L flows through the diode D when the switching element S is turned off, the ratio between the output voltage E 0  to a load RL and the input voltage E i  (a conversion characteristic) becomes E o /E i =1/[1+(1-X)/n.X], where X is a duty ratio at which the switch S is turned on, and n is a proportionate position of the tap of the inductance L.

Abstract: PURPOSE:To always hold a uniform space mutually between objects by providing a drive unit, which is reciprocated and engaged with each collection-dispersion object to move a guide frame, and an endless drive chain in which one of the large and small compound chain wheels is driven by one of the forward and return paths of the drive unit and the other of the chain wheels is driven by the other path. CONSTITUTION:When a drive mechanism in an end part chain wheel 6a is turned, a chain 6 is started to circulate, and a small wheel 5a of each compound chain wheel is turned by a forward path in an upper side, while a large wheel 5b is turned similarly in the clockwise direction by a return path in a lower side. In both the forward and return paths, the chain 6 is advanced by the same number of pitches with both the small and large wheels 5a and 5b turned by the same number of teeth, and by increasing a rotary angle in the small wheel 5a to roll-advance the large wheel 5b on the chain 6 by that amount, the larger is a difference between numbers of teeth in the large and small wheels of the compound chain wheel 5, the larger and faster a drive unit 4 is moved. Accordingly, by gradually increasing the difference between the numbers of teeth in the large and small wheels of the compound chain wheel 5 successively from the right end, each drive unit 4, uniformly holding its adjacent space, is opened and closed. In a movable louver in which this device is used, good appearance is obtained by uniformly holding a space between blade plates even when their open-close action is stopped halfway.
