IPC: H02M3/155
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To quicken the switching operation of each transistor at the step-down section and the step-up section by feeding a part of the output signal from a choke coil back to each transistor at the step-down section and the step-up section through a feedback circuit, formed by connecting a capacitor in series with a feedback winding coupled with the choke coil. SOLUTION: First and second transistors 2, 5 are applied, to the bases thereof, with a high-frequency control signal from a control circuit 10 and an electromotive force is induced across a choke coil 4 at a same frequency as the control signal. The electromotive force is induced in a feedback winding 11, coupled electromagnetically with the choke coil 4, and a capacitor 12 repeats charge/ discharge with the oscillation period of the control signal. Since a feedback circuit 13 is connected in parallel with the bases of the first and second transistors 2, 5, i.e., the control section thereof, terminal voltage of the feedback circuit 13 is superposed on the voltage of the control signal at the control section. Consequently, the voltage waveform becomes steep and the rising/falling time is shortened.

Title: Plastic ampule
Inventor: BERUNTO HANZEN
IPC: B65D1/02
Filed: 1989-07-11
Abstract: PURPOSE: To make an opening diameter of an ampul large by making a conversion part to an ampul head part with a specified shape and size to be a neck part shape which is a wedge shape and becomes narrower inside in a radial direction and limiting a thin wall thickness part to be a ring region to form a separation point. CONSTITUTION: A wall of the base part of a neck part 4 of this ampul is teared out by throwing down the ampul head part 5. Because necessary force to throw down the ampul head part is small, it is not necessary to grasp the ampul heat part with two fingers. Even if the opening diameter is comparatively large, it is possible to throw down the ampul head part. For example, it is possible to push the ampul head part by a swelling of a thumb root. Furthermore, because a region where thickness of the wall is thin is very narrow, a clear outline edge can be obtained regardless of diameters of the opening, even if the opening diameter is relatively large. In addition, the wall thickness becomes thin at the separation area and the opening diameter is over 3mm and desirably to be more than 5mm.
