A converter includes a converter circuit 1 having a plurality of bridge-connected semiconductor switching devices for converting AC power into DC power, a smoothing condenser connected in parallel to the DC side of the converter circuit and a current detector provided in a condenser circuit to control a condenser current flowing through the smoothing condenser to be a set value. The condenser current is controlled to be the set value (e.g. zero) to thereby reduce the capacity of the smoothing co...

A convertible assembly that is adapted to hold a folded flexible container capable of being unfolded to a relatively large volume container and to effectively serve as the neck of that container when the latter is extracted and unfolded, comprising a rigid tubular member having reduced diameter opposite end portions formed with threads for mounting screw thread caps, and an internal ring mounted within the tube whereby upon removal of the caps and extraction of the folded container the neck of t...

A band-shaped annuloplasty device (e.g., C- or D-shaped ring) that is relatively rigid during handling and implantation and becomes relatively complaint after implantation. Preferably, the device includes a core material that softens after implantation.

This invention relates to a capsule which comprises a glass-shaped body with a funnel-shaped bottom having a central hollow extension which can be cut off, an upper closure baffle which can be pierced in order to introduce a diluent, a sealing disc comparatively flexible which is inserted into the glass-shaped body until the latter rests along a continuous supporting edge to ensure the seal by means of a slight forcing; and, below said supporting edge, projections contacting the disc and deformi...

An article of manufacture is disclosed for absorbing liquids, particularly body fluids such as menses. The disclosed article is disposable and has a wrapper associated therewith. An elastic material is secured to the backsheet and is maintained in a substantially tensioned state until separation of the wrapper from the backsheet. Upon separation of the wrapper from the backsheet the tension in the elastic member is released causing the disposable absorbent article to form an upwardly cupped conf...

Polymeric reaction products which become water-thinnable on protonation with an acid and are suitable for use in the form of aqueous dispersions as additives in electrocoating baths are formed from A. a butadiene/acrylonitrile copolymer which contains primary and/or secondary amino groups and B. an epoxy compound having an average molecular weight of from 140 to 10,000 and containing on average from 1.5 to 3 epoxy groups per molecule, the amount of (A) being such that 1.05 moles or more of prima...

A plasma display device provided with a green color phosphor which is charged entirely with a positive potential, adsorbs only limited amounts of water, carbon monoxide, carbon dioxide and hydrocarbon, and not liable to cause chemical reaction thereto. The green color phosphor used is a combination of any of phosphors defined by the general formula of MMg.sub.1-xAl.sub.11O.sub.19:Mn.sub.x (where "M" denotes one of La and Ce) having a magnetoplumbite crystal structure, yttrium borate group and yt...

The invention relates to a process for the preparation of a gel material which is not free-flowing, is reversibly transparent as a function of temperature and comprises nonionic and/or nonionically acting surfactants as clouding components. The preparation of the gel material can be integrated into the customary production process for laminated glazing in a simple manner and produces frost-stable glazing which can be employed universally indoors and outdoors. When applied, the strength of the sy...

An inflatable object including an electronic module with a voice/music chip or an illumination device and at least one battery within confines of the inflatable object, an insulator being configured and arranged in a disabling position to prevent powering of the electronic module by the at least one battery, and an end of the insulator being secured to an inside surface of the inflatable object so that as opposite sides of the inflatable object spread apart in response to inflation of the inflat...

The semiconductor of the present invention comprises: a buffer circuit (40) which operates by the supply of a first power source potential VDD1, and an N-type MOSFET (10) connected between a pad (20) pulled up to a second power source potential VDD2 and a ground. An output line (42) of the buffer circuit (40) is connected to a gate of the N-type MOSFET (10). The semiconductor further comprises a potential setting circuit (50) which sets a potential of the output line (42) of the buffer circuit (...
