Title: Back-type dc-dc converter circuit
Inventor: MATSUDA YOSHIAKI
IPC: H02M3/155
Filed: 1993-02-18
Abstract: PURPOSE:To make it possible to prevent the switching loss of a switch element by using the resonance action of a capacitor and a choke coil, which are connected to a flywheel diode in parallel. CONSTITUTION:When a main switch (MS) Q1 is turned ON, a current Q11d1 flowing through the MSQ1 is commutated into a capacitor (CD) C1. When the voltage of the CDC1 reaches a DC power supply Vi, the energy accumulated in a choke coil (CC) L1 is made to pass through a flywheel diode (FD) D2 and regenerated. When an auxiliary switch element (AS) Q2 is turned ON, a current IF2 flowing through the FDD2 is shunt into the ASQ2 and reaches a load current IO. When a current Q2Id2 reaches the load current IO, the voltage of the DDC 1 is discharged. When a voltage Q1VDS becomes zero, a current Q2Id2 flows through the diode D1 by the action of the CCL2. Since the current Q2Id2 reaches the load current IO, shunting is started into the MSQI.

IPC: F16C32/04
Filed: 1980-04-22
Abstract: PURPOSE: To enable a rotating body to pass a critical rotating speed therefor without generating excessive vibration by a method wherein a rotatable and slidable damper is attached to the rotating body such as a centrifugal separator or the like rotated in a high speed to provide it with a vibration damping force in a condition that the rotating body is floated in air perfectly.  
     CONSTITUTION: The damper 9 is attached to the rotating body 1. One part 9a of the damper 9 is rotatably and slidably attached to the other part 9b of the damper 9 and liquid 10 is held in a clearance between both of the damper parts 9a, 9b. When the axial center 7 of the rotating body 1 is moved to another axial center 7' and a vibration is generated, a relative speed is generated between the damper parts 9a, 9b which are vibrating integrally with the rotating body 1 and the liquid 10 is sheared. Accordingly, the damping force generated in proportion to the relative speed operates so as to restrain the vibration of the rotating body 1 and reduces the vibration upon passing the critical speed thereof thereby enabling to increase the number of revolution into the area of the high speed rotation easily.
