Patent EP-0160248-A2 (EP)
Inventor: BADAMI DINESH ARVINDLAL
IPC: G03F7/20
Filed: 1985-04-17
Abstract: A optical photolithographic process in which resist lines having widths in the micron and sub-micron range are produced without the use of a fragile photomask. A positive photoresist having an additive for image reversal is applied to the surface of a semiconductor substrate (10). The photoresist is exposed through a photomask (30) to ultraviolet light. The edges of the opaque sections of the mask diffract the ultraviolet light, forming partially exposed areas (24) between the exposed (22) and unexposed areas (26) formed in the photoresist. After development in a solvent to remove the exposed areas, the photoresist undergoes an image reversal process. The photoresist is first baked at 100°C for 30 minutes. During this bake step, the photoactive decomposition products present in the partially exposed areas (24) react, freezing the solubility of the partially exposed areas (24) with respect to that of the unexposed areas (26). The photoresist is then blanket exposed and developed in a solvent, leaving the partially exposed areas (24) on the substrate. The resulting thin resist lines can be used to form narrow isolation trenches by coating the substrate with a quartz film and lifting off the resist lines.

Abstract: A sewing machine is driven by step by step motors. In order to improve this sewing machine the zig-zag movement of the needle is made by the motion imparted by one of the step by step motors which shifts a rack 4 in a continuous to an fro motion, thus rocking a centrally connected lever. By means of an end rod it moves a cambered double-shaped lever with curved end, joined at the center to the needle shaft 18, which is connected at its upper point and enables this to rock so as to achieve the zig-zag motion of the needle (fig. 1).

Abstract: A guidance system for an unmanned transporting vehicle which runs along a guide track. The guide track is composed of a belt-shaped light reflective material and laid out on a floor or the like. The unmanned transporting vehicle has two rows of photodetectors longitudinally arranged thereon forwardly of the front wheel. Since the two rows of the photodetectors are spaced apart from each other with a distance less than the width of the guide track, increasingly forwardly photodetectors begin failing to detecting the guide track earlier when the vehicle runs off the guide track. The vehicle is equipped with control means for controlling the steering mechansim of the vehicle in response to the detection count value such that the front wheel is swivelled to correct the vehicle deviation at a sufficiently early stage.

Abstract: A device for removing dust and other fine particulate matter from the exterior surface of a bottle moving along a conveyor line. A jet of ionized air neutralizes any static charge adhering the particulate matter to the bottle and also commences the dislodgement of the former from the latter. Moving brushes contacting the exterior surface of the bottle further dislodges the particulate matter. Lastly, a vacuum on the other side of the brushes from the bottle removes the air and entrained particulate matter detached from the bottles. A star wheel having indentations in it moves the bottles along a predetermined pace. Alternately, one or more rotating longitudinal screws can control the bottles motion through the system. A belt in contact with the bottles and moving relative to the conveyor effects their rotation regardless of their exterior configuration. This assures that the brushes contact all portions of their exterior surface. The star wheel has rollers attached to it which maintain the belt in an extended configuration and keeps it in intimate contact with the bottles. When the device utilizes a longitudinal screw, the belt can rotate around rollers placed at the ends of the screw.

Abstract: A system and method are disclosed for automatically detecting any change in average printhead resistance due to continued usage of the printhead and for automatically correcting for such resistance change in order to maintain constant printing energy. In a preferred embodiment a voltage regulator (49) is turned off during a test mode of operation to test or measure each of the thermal elements in a thermal printhead (11) by allowing constant current to flow sequentially through the thermal elements (R,-R<sub>N</sub>) thereby developing a sense voltage which has an amplitude proportional to the resistance of the element being measured. The sense voltages for the elements (R<sub>1</sub>-R<sub>N</sub>) are sequentially converted into digital signals by an analog-to-digital converter (63), summed together and averaged in order to develop an average printhead resistance. Each subsequent average printhead resistance is compared against the inital average printhead resistance to determine whether a change in average printhead resistance has occurred. In response to a change in average printhead resistance, a processor (25) maintains constant printing energy during a printing mode of operation by changing the pulse width of the printing pulse and/or by changing the head voltage accordingly.

Abstract: For serial data exchange between more than two subscribers (T1 ... Tn), each subscriber has only one central processor (PCU) with only one serial interface (T<x>D, R<x>D) for data exchange, and is connected via two couplers to two independent data busses. Each of the two couplers can be switched independently from the other by the processor (CPU) to reception and/or transmission. An electronic monitoring device (watchdog) is assigned to the processor (CPU) to monitor it constantly so that, if malfunctions or faults develop, the signal lines (DE1-DE1 or DE2-DE2) are blocked for "Enable transmission" to the two couplers, thus blocking data output. A defective subscriber installation can thus be effectively taken out of service, while data traffic can continue to be carried between the remaining, correctly functioning subscriber installations via the two data busses. <IMAGE>

Abstract: A system for producing a digital representation of the value of an angle e, typically a phase angle, from two analogue input quantities representative of A sin θ and A cos θ, where A is an amplitude factor, comprises logarithmic amplifiers (IC1-IC4) which produce analogue representations of a plurality of quantities (sin e, cos θ, sin (θ + 3π/4), cos (θ + 3π/4)) derived from the two input quantities and which are arranged to add or substract their outputs to produce quantities (V 1 -V 4 ) which are independent of A and the value of each of which lies within a predetermined range (-C to +C) in at least one respective portion (2π/n) of an angular range for θ of 2 π radians. The digital representation of θ is the concatenation of digital representations of the angular portion (2π/n) in which θ lies and of the value of θ within the portion that is derived from the selected appropriate one of the quantities Vi-V 4  with an analogue to digital converter. Such a system enables high resolution to be obtained at a high operating speed. Suitably, the quantities Vi-V 4  vary linearly with e in their respective angular portions and are [log tan] functions of θ.
