Title: Super fast semiconductor switching apparatus at arbitrary time for AC power source
Inventor: TAI CHENG-YAO
IPC: H01H36/00
Filed: 2000-06-09
Granted: 2001-10-01
Abstract: The present invention relates to a kind of super fast semiconductor switching apparatus at arbitrary time for AC power source (2). Each phase of AC power source for the single phase or three-phase load is serially connected with a controllable first semiconductor device. Each of the first semiconductor devices is connected in parallel with a reverse diode. On the wire connection between the first semiconductor device of each phase and its load, another wire connection is individually connected in between two diodes of the same phase rectification bridge. In addition, a parallel connection state is formed between the rectification bridge of each phase and the second semiconductor device. The second semiconductor device is connected in parallel with the other reverse diode. An opposite switching action is then formed between the first and the second semiconductor devices. By turning-off the first semiconductor device of one phase to cut-off AC power source, the load current returns to the load by passing through the corresponding phase rectification bridge, the second semiconductor device and the rectification bridge of the same phase so as to constitute a continuous flow loop and prevent the occurrence of instantaneous super high voltage. Therefore, it is capable of promptly switching on/off AC power source at arbitrary time.

Title: Twin screw rotors and displacement machines containing such
Inventor: BECHER ULRICH
IPC: F04C18/08
Filed: 2001-07-23
Granted: 2004-05-11
Abstract: The twin screw rotors for axis-parallel installation in displacement machines for compressible media have asymmetrical transverse profiles and numbers of wraps that are >= 2. Depending upon the wrapping angle (alpha), the pitch (L) varies, which pitch increases in a first subdivision (T1) from the suction-side screw end, reaches a maximal value (Lmax) after one wrap, decreases in a second subdivision (T2) until a minimal value (Lmin), and is constant in a third subdivision (T3). The pitch course in the first subdivision (T1) is preferably mirror-symmetrical to that in the second subdivision (T2); within the subdivisions T1 to T2, it is point-symmetrical to the mean values in almost all cases. Compact screw rotors, completely free of imbalance, can thereby be achieved with compression rates of 1.0 ... 10.0, also without profile variation. Such rotors offer the best prerequisites for reduction in energy requirements, temperature, construction size, costs, as well as for free selection of working materials in applications in chemistry, pharmacy, packaging, and semiconductor technology.
