Patent EP-0358266-A2 (EP)
Inventor: HUGHES JOHN BARRY
IPC: H03F3/34
Filed: 1989-09-01
Abstract: An operational amplifier circuit comprises a differential input stage (22) and an output transistor (N3) driven by an output (24) of the differential input stage. Means (N4, P3, P5) for generating a bias current for the differential input stage are constructed so that in operation the bias current is in a predetermined proportion to the current flowing in the output transistor (N3) and is substantially independent of the impedance (Z) of any load driven by the output transistor, thereby eliminating a systematic offset error. The means for generating the bias current may include a further transistor (N4) driven by the output of the differential input stage.

Abstract: Acrylic hot melt pressure sensitive adhesive compositions having a good balance of tack, peel and creep resistance at ambient temperature combined with optical clarity and desirable melt viscosity at elevated temperatures are prepared by copolymerizing acrylic and methacrylic alkyl esters of a non-tertiary alcohol or optionally acids with polymerizable poly methacrylate based macromonomers. The resulting acrylic copolymer has a graft or comb structure in which the acrylic backbone has a low Tg and the pendant macromonomer side chains have a Tg above room temperature. 
     Compounding these acrylic copolymers with tackifiers and plasticizers dramatically improves the balance of pressure sensitive adhesive properties while lowering melt viscosity into a desirable range. The invention provides significant property enhancements even for acrylic copolymers having poor initial peel and shear adhesive properties. Preferably, the acrylic backbone is tailored by judicious selection of acrylic comonomers to allow compounding with several high performance hydrogenated tackifiers and plasticizers that provide water white and clear adhesive formulations while ensuring long term color stability, weatherability and general durability.

IPC: B21K1/56
Filed: 1989-01-11
Abstract: The process is carried out using a press tool which has a plurality of dies which are arranged around a longitudinal axis and are radially displaceable with respect to this axis. The radially inner surfaces of the dies correspond to segments of the conical thread to be pressed. During pressing of a conical thread in cylindrical workpiece, the dies are first drawn apart in the radial direction and the workpiece is then pushed between the dies, along a length which corresponds to only a few thread turns. The dies are then pressed toward one another in order to press into the workpiece a short conical thread in which only the first thread turn may be formed to its full depth. After the dies have been drawn apart, the workpiece is displaced between the dies through a further length which once again corresponds to only a few thread turns. When the dies are pressed toward one another again, the previously pressed thread turns are pressed deep into the workpiece and additional thread turns are formed. This process is repeated several times until the conical thread has been pressed to the predetermined total length.

In order that there are no holes in the finished container, during the injecting operation the pins (11) are drawn away from the rods (9) to an extent determined by the injection pressure prevailing in their vicinity, which varies according to the filling level of the plastic, until their end face is flush with the surface of the part of the apparatus from which they protrude. <IMAGE>

Abstract: To prevent gear shift shock in a vehicle power train associated with a turbocharged engine (10) and an automatic transmission (12), an air charging efficiency for engine cylinders is reduced during the gear shifting transient period, e.g., when shifting from first gear range to a higher second gear range. Therefore, when engine output is reduced by means of retardation of ignition timing at the time of gear shifting, no misfire occurs due to prevention of internal pressure increase in any engine cylinder. Thus, shift shock can be prevented with the smooth reduction of engine output and air charging efficiency is smoothly recovered after completion of the gear shift transient period.

Abstract: A light emitting diode printhead has a row of LED dice, with each die having one or more rows of LEDs. The LED die substrate forms a common cathode for the LEDs on that die. There is a time multiplex driver for a plurality of dice comprising a plurality of current sources. Each current source comprises a current driver FET and a data FET in series. Each data FET is connected in parallel to the anodes of corresponding LEDs on all of the dice. Switches selectively connect the substrate of each die to ground. A latching shift register is used for applying data for a selected die to the data FETs. The register is divided into the same number of blocks as the number of dice, and each block has the same number of bits as the LEDs on a die. At the same time a block of data for a selected die is connected to the data FETs, the substrate of the selected die is connected to ground, thereby enabling only the light emitting diodes on the selected die.

Abstract: This invention relates to an image scanning apparatus and more particularly to the scanning apparatus for use in a digital copier which obtains a negative image from an image of an original. A color image signal is generated from an image sensor by sensing a reflected light from an original through a scanner and an optical filter, and is converted to an image data consisting of a color code and a luminance data. Color histograms and summarised histogram are produced from the image data, which represent luminance distributions for each color code and a total luminance distribution. A pattern class for each histogram is identified by checking histogram shape, and coefficient data of mutual transfer function and gamma data are selected from data tables according to the identified pattern class. The luminance data are corrected in accordance with the selected coefficient data and gamma data.
