Patent DE-19700401-A1 (DE)
Inventor: MATSUMOTO AKIHIRO
IPC: H02M3/335
Filed: 1997-01-08
Abstract: In a lighting circuit for operating a discharge lamp 28 from a DC source, such as a battery 16, via a DC/DC converter 20 feeding a converter 21, the negative side of source 16 is grounded, the output side of converter 20 is isolated from its input side by means of a transformer 20a, and the high side output line of converter 20 is also grounded so that the converter 21 can supply the lamp 28 with negative pulses (Fig.2). Because of the use of negative pulses, proximity of a metal member (such as reflector) to the lamp does not result in leakage of metal ions from the lamp, thus avoiding a prior problem of impaired colour rendering. The DC/DC converter 20 is controlled by a circuit 25 responsive to a detector (10', Fig. 1) which senses lamp voltage and/or current, or to a detector 22,23,23' which senses an output voltage and/or current of the converter 20, equivalent to the lamp voltage and/or current. A protection circuit 29 also responds to the detector to stop power supply to the lamp when an abnormality in the lamp or in the circuitry is detected. Inverting amplifiers (Figs.5,7) are used to convert negative outputs from the detector to positive signals suitable for application to the control and protection circuits 25, 29. A power supply for the control and protection circuits 25, 29 is provided from the source 16 via an auxiliary power supply 30 which provides outputs Vcc1, Vcc2 which are positive relative to ground.

Inventor: WEBER KLAUS
IPC: B29C65/48
Filed: 1997-04-30
Abstract: The invention relates to a method for gluing two substrates (3, 6) to a substrate disk (23), wherein an adhesive is applied to the surface of the first substrate (3, 6) which is to be glued and the surface of a second substrate (6, 3) which is to be glued is placed on top of the first substrate (3, 6).

Abstract: The twisted polyester multifilaments are used in a drive belt, which is placed under tension between two disks.  After 48 hrs., the belt tension has dropped by not more than 35% from the start value, and does not drop further after this time The polyester multifilaments are not of high module filaments, twisted in a single- or multistage. The twisted material (1) has a thickness of 800-1700 dtex, with twisting stages of 0-250 twists/m, 0-10 twists/m and 50-250 twists/m.

The third zone has a lower constant temp. in a range of -20 deg C to +140 deg C. Preferred Features: The first zone has a constant temp. of 60-160 deg C, the constant temp. in the second zone is 160-260 deg C and, in the third zone, there is a constant temp. of -20 deg C to +140 deg C.
