Title: Alternating current controller
Inventor: MAIER REINHARD
IPC: H03K17/08
Filed: 1993-09-08
Abstract: PCT No. PCT/DE93/00825 Sec. 371 Date Mar. 8, 1996 Sec. 102(e) Date Mar. 8, 1996 PCT Filed Sep. 8, 1993 PCT Pub. No. WO95/07571 PCT Pub. Date Mar. 16, 1995An AC power controller includes at least two semiconductor regions reverse-connected in series. Each semiconductor region has an electron donor (source), an electron sink (drain) and an electron flow control electrode (gate) with characteristic curves such as those exhibited by FETs. Each semiconductor region also has an internal body diode. The gate-source voltage of a respective semiconductor region in the forward direction is set to be large enough to establish a desired limiting of the drain-source current. Yet, the gate-source voltage of the semiconductor region in the inverse mode is set to be large enough for the body diode to remain de-energized.

Title: Tv image projecting system with rearward projection
Inventor: NEGISHI NORIAKI
IPC: H04N5/74
Filed: 1996-09-27
Abstract: One kind of housing has been formed for rear projection televisions of each screen size in inches and it has not been possible to change the size in inches for such a housing. This has reduced productivity and resulted in a cost increase. An upper cabinet (11) and a lower cabinet (12) of a rear projection television are separable formed. A screen (13) and a mirror (15) are provided on the upper cabinet (11). A main component portion for a television comprising video devices, driving and control circuits, an optical unit including a projection lens (20), and a light source (21) is provided on the lower cabinet (12). Upper cabinets of different screen sizes in inches may be assembled with a common lower cabinet to allow rear projection televisions of various sizes in inches to be easily manufactured. <IMAGE>

Title: Method for manufacturing a fibre mat, fibre mat and use of such fibre mat
Inventor: PALLESEN BODIL ENGBERG
IPC: D04H1/04
Filed: 1999-04-29
Abstract: There is described a new method for making a fibre mat under the use of plant fibres, preferably from flax and hemp. The fibres are pre-treated and shortened, whereafter they are separated for establishing a fibre mass comprising single fibres with lengths within a desired interval. Hereafter, the fibre mat is produced by a dry-forming process as the fibres are oriented randomly in the fibre mat. The dry-forming process preferably takes place by using a former head which is placed above a vacuum box as the fibres are deposited on a former wire between these two elements. The plate is fixed as inter-fibre bonds are established between the single fibres. The inter-fibre bonds may be established with or without the use of binders. The formed fibre mats will be open and airy, but at the same time sufficiently stable and cohesive for handling. A field of application for the fibre mat will be isolation.
