Patent EP-0163843-A2 (EP)
Inventor: DIETRICH RAINER DR DIPL-ING
IPC: B23D61/02
Filed: 1985-04-03
Abstract: Tools (10) which are used in particular for working rock, apart from being subject to the wear caused by the actual working operation on the rock at their active working edges and faces, are likewise subject to wear at the passive tool flanks (15) and sides which are not in direct contact with the rock but only have cooling lubricants flowing against them. This wear of the passive tool flanks (15), which is due to erosion, cavitation and corrosion effects and considerably reduces the service life of expensive working tools, is to be rectified. For this purpose, it is proposed that the wear protection layer (12) at least partly surrounding the basic body (11) of a tool (10) of this type be formed of a soft material so that the processes causing the abrasion or the wear are neutralised in their adverse effect by energy absorption or particle reflection. <IMAGE>

Abstract: A door window regulator for vertically moving a door window glass of a vehicle includes a guide member and a slider which is secured to the door window glass and guided by the guide member. A wire is stretched between upper and lower pulleys respectively disposed atthe upper and lower portions of the quide member and is connected at its intermediate portion to the door window glass. Thus, the door window glass is vertically moved by the driving force derived from a wire driving unit. A wire guide shoe projects from the guide member such as to contact the portion of the wire between the upper and lower pulleys, whereby the wire is bent between the upper and lower pulleys to thereby reduce the space occupied by this door window regulator.

Title: Television transmitter
Inventor: PLUME EDWARD GEORGE
IPC: H04N5/38
Filed: 1985-09-12
Abstract: A television transmitter comprises a video signal input (1) feeding a modulator (2), a pre-corrector (3), an up converter (4) and power amplification stages (5, 6). The stage (6), typically a Klystron amplifier, is operated in a non-linear mode to increase efficiency and the pre-corrector (3) is provided to provide a correction for the output amplifier stage non-linearity. A portion of the output signal is coupled to a demodulator (8) whose output is fed to measurement means (9). The measurement means (8) measures the distortion of the output, for example non-linearity, differential gain, etc., and applies a signal to a computer (11) via an interface circuit (10). The computer then calculates control signals which are applied through the interface circuit (10) to the pre-corrector (3). The control signals are effective to vary the transfer characteristic of the pre-corrector circuit (3) in such a manner as to reduce the output distortion to a minimum value.

Abstract: This application discloses a thermal ink jet printhead and related integrated pulse driver circuit useful in thermal ink jet printers. This combined printhead and pulse drive integrated circuit includes a first level (5,6) of metallization compri­sing a refractory metal which is patterned to define the lateral dimension of the printhead resistor (4). A passivation layer or layers (7,8,9) are deposited atop this first level (5,6) of metalization and patterned to have an opening or openings therein for receiving a second level (10,11) of metalization. This second level (10,11) of metallization such as aluminium may then be used for electrically interconnecting the printhead resistors (4) to MOSFET drivers and the like which have been fabricated in the same silicon substrate (1) which provides suport for the printhead resistors (4). Thus, this "on-chip" driver construction enables these pulse driver transistor to be moved from external electronic circuitry to the printhead substrate.
