Abstract: PURPOSE:To disable the switch of a card reader to be operated when no card is inserted into an insertion opening by inserting a card to release the lock with a locking means. CONSTITUTION:When the locking means 18 is in a locked state, an operating element 20 is inserted into a sleeve 23 and the engaging part 33b of an operating plate 33 is fitted in the engaging recessed part 22 of the element 20.

Title: Resonating dc-dc converter
Inventor: MAEDA MIKIO
IPC: H02M3/335
Filed: 1978-05-11
Abstract: PURPOSE:To eliminate simultaneous conducting of transistors by additing a capacitor between the middle point of the pirmary winding of a conversion transformer and the positive of the power supply to form a resonance circuit with the inductance of the primary winding. CONSTITUTION:A resonating DC-DC inverter is made up of switching transistors Tr1 and Tr2, a satulation transformer T1, and a conversion transformer 2, while a capacitor C2 is added in series between the middle point C of the primary winding N1 of a conversion transformer T1 and the positive of the DC power supply E. With such an arrangement, the collector current of the switching transistors Tr1 and Tr2 is converted to a sine wave with resonance current waveform which rises slowly. Thus, the rise time can be ignore. This can eliminates simultaneous conducting of the two transistors during altimate on/off operation thereof, thereby reducing thermal destruction and spike noise.
