Title: Bleaching mask
Inventor: HOEKSTRA TSJERK HANS
IPC: G02B6/13
Filed: 1995-06-23
Abstract: The  invention  concerns  a  method  of  making  a  polymeric  optical waveguide component employing a waveguiding material susceptible to a change of refractive index when subjected to irradiation of the proper wavelength,  i.e.  a bleachable polymer,  in which the mask used for defining  the  areas  to  be bleached  is  in the  form of a  developed photoresist that is not substantially transparent to the irradiation wavelength. Thus, a simplified process is provided by which a pattern of laterally defined waveguide channels can be made in a polymeric optical   waveguide.   The   photoresist   substantially   absorbs   the wavelength used for bleaching. This may be accomplished by employing dye molecules which absorb energy of the proper wavelength.

Abstract: A digital video tape record/playback apparatus (Fig. 10) for processing a high definition television signal includes provision for controlling the occurrence of high priority (HP) image information. Such information is selectively recorded at normal speed in tape tracks within predetermined regions (HP1-HP5) so as to appear along a tape head scanning path associated with predetermined tape playback speeds greater than normal (e.g., 20x normal). Input high priority data cells may be reordered or duplicated for recording in the predetermined tape regions in other than received order. In either case, the input datastream is massaged to produce a viewable image in a fast playback mode. In an illustrated system for receiving an MPEG coded datastream, an output datastream at greater than normal playback speed comprises either intracoded I-frame data cells only, or a whole Group of Pictures (GOP).

Title: Mineral wool product, method for its production, impregnating mass therefor, and use thereof
Inventor: KUMMERMEHR HANS
IPC: C04B28/24
Filed: 1994-11-11
Abstract: The surfaces of coated mineral fiber products, as a rule, also form a barrier against dust and trickling particles, are however not accepted for technological reasons and reasons of cost unless their intended use requires coating or impregnating for different reasons. In order to provide such mineral wool products, which - in view of their use usually are not coated, with a barrier against dust or trickling particles, it is proposed to provide their surfaces with an impregnating mass applied in a foamed form. The froth is destroyed during drying or curing to open macroscopic pores between the fibers, whereby an open surface structure of the product is preserved. Nevertheless the impregnated layer offers effective protection against solid matter passing through it. Impregnation by means of a foam incurs surprisingly low additional costs, even in large series production. It is of particular importance that by selecting a suitable impregnating mass, the tactile sensation of the product may be modified in a desired manner such that the product will e.g. be softer or warmer to the touch.

Filed: 1996-06-14
Abstract: An integrated circuit output driver which reduces the effect of power supply and/or integrated circuit fabrication process variations on signal propagation delay.      The output driver produces an output signal V out as an increased drive strength replica of an input signal V in. A pre-driver receives V in and produces an intermediate, inverted replica V int thereof. A driver is electrically connected to the pre-driver's output to receive V int. V out appears at the driver's output as an inverted, strengthened replica of V int. A first feedback circuit electrically connected between the driver's input and output applies a pull-down signal to the driver's input in response to a falling edge of V in, with the pull-down signal's strength varying in inverse proportion to propagation delay of the falling edge of V in. A second feedback circuit electrically connected between the driver's input and output applies a pull-up signal to the driver's input in response to a rising edge of V in, with the pull-up signal's varying in inverse proportion to propagation delay of the rising edge of V in.
