Title: Static power conversion method and apparatus
IPC: H02M7/797
Filed: 1987-09-25
Granted: 1992-07-15
Abstract: A high efficiency power converter is achieved utilizing a resonant DC link between a DC source, such as a converter rectifying power from an AC power system, to a variable frequency voltage source inverter. A resonant circuit composed of an inductor and capacitor is connected to the DC power supply and to a DC bus supplying the inverter and is caused to oscillate stably at a high frequency to provide a uni-directional voltage across the DC bus which reaches zero volts during each cycle of oscillation of the resonant circuit. The switching devices of the inverter are controlled to switch on and off only at times when the DC bus voltage is zero, thereby eliminating switching losses in the inverter. The resonant circuit can be caused to oscillate utilizing pairs of switching devices in the inverter or a separate switching device across the capacitor, which again are caused to switch on and off only at times of zero voltage on the DC bus. For AC to AC conversion, enabling bi-directional power flow, the switching devices of the power source which converts AC power to DC power may have switching devices which are also switched only at the times of zero voltage so that switching losses in these devices is also minimized.

The two tiller end sections (13, 14) are connected flexibly to the ends of the center section by frame to frame hinges (22) and by cutter to cutter universal joints (24), so that the end sections can rotate freely about the hinges (22). The tiller center section (12) is secured to the towing mechanism (11) to oscillate about a central horizontal axis (29) in the direction of travel. The oscillating center section (12) and the two pivotally attached end sections (13, 14) cooperate to enable the tiller (10) to closely conform to and thoroughly groom rolling snow paths without reducing them to flat ones. The rolling paths are enjoyable to ski, and are slower and safer. A controllable hydraulic ram (36, 37) is mounted to act across each hinge (22), so that the operator may select the degree of bending permitted at each hinge (22), and may hydraulically lock it into selected position, if desired.

Granted: 1993-06-16
Abstract: To equalise the distribution of voltage at a series circuit of gate-controlled semiconductors (V1, V2) having turn-off times of different length, it is first determined by delivering the turn-off signals at the same time, with a low current flowing through the series circuit, which of the semiconductors (V1, V2) is the last one to turn off. Then the deliveries of the turn-off signals to the semiconductors (V1, V2) which previously turned off earlier are in each case delayed at higher currents until, finally, at full operating current, until these semiconductors turn off at the same time as the semiconductor with the longest turn-off time. This delay can be compensated via load-current-dependent correction elements (K1, K2) at the ratio of the instantaneous turn-off current values of two successive conductive phases of the series circuit. <IMAGE>

The head section can be driven by hammer blows into a wooden member. Initially, the anchor bolt and expansion wedge are in detachable engagement until the head section is driven into the wooden member. Subsequently, as the expansion wedge is axially displaced relative to the anchor bolt, the engagement between them is released and the anchor member assembly is secured in the receiving material.

Abstract: Le dispositif électrique décrit permet la conversion de molécules de faible poids moléculaire, telles que du méthane, en molécules de poids moléculaire plus élevé, tel que l'hepthane et l'octane. La chambre de réaction contient un réseau de tubes diélectriques parallèles (32) avec une couche semiconductrice sous leurs surfaces internes (34), cette couche servant à la circulation du courant. Pendant le fonctionnement, des électrons frappent la surface interne (34) des tubes (32), ionisant ainsi des molécules absorbées sur les surfaces, ces molécules étant ensuite accélérées par le champ électrique et transportées vers un nouvel endroit en surface où elles se combinent avec des molécules absorbées à cet endroit pour former une variété de nouvelles molécules plus grandes. L'hydrogène en excès dans un état ionisé est éliminé, en étant accéléré par le champ électrique vers les extrémités opposées des tubes. Dans certaines conditions de fonctionnement, de grandes molécules peuvent être segmentées en molécules plus petites. L'ionisation par impact d'électrons commandée dans le dispositif peut également produire des réactions parmi plusieurs espèces moléculaires qui seraient improbables ou impossibles dans des conditions normales d'équilibre chimique, ou avec des catalyseurs normaux.

Abstract: A vertical semiconductor device having a plurality of vertical active regions and a method for manufacturing such a vertical semiconductor device. In the preferred embodiment, a vertical multicollector pnp transistor is formed by disposing a plurality of n type epitaxial layers (20, 30) over a bottom p type substrate (10). Each epitaxial layer (20, 30) has a plurality of collector regions (27, 28) formed therein. The collector regions are connected using a single diffusion step to form vertical collectors (67, 68) for the pnp transistor. The base (55) is formed from the epitaxial layer (30) and the emitter (35, 36) is formed using a separate implant or diffusion step. Vertical isolation regions (51, 61, 52, 62, 53, 63) are formed contemporaneously with the vertical collectors. The resulting pnp transistor has vertical collectors and isolation regions formed with less silicon, fewer diffusion steps, and more precise and reduced dimensions.
