Patent EP-0222796-B1 (EP)
IPC: H04N1/40
Filed: 1986-04-24
Granted: 1990-03-21
Abstract: A problem in digital image processing is to automatically generate a tone reproduction function that maximizes the quality of the processed image. In an improved method for generating the tone reproduction function by normalizing a sample of tone values, the sample is selected from an image dependent ''floating'' contrast interval using the statistical parameters of the sample itself for the selection.

Abstract: A method for the manufacture of LSI complementary MOS field effect transistor circuits to increase the latch-up hardness of the n-channel and p-channel field effect transistors while retaining good transistor properties by incorporating a further epitaxial layer and highly doped implantation regions into a lower epitaxial layer from which the wells are generated by out-diffusion into the upper epitaxial layer. In addition to achieving optimum transistor properties, the reduced lateral diffusion provided enables a lower n+/p+ spacing, and thus achieves a higher packing density with improved latch-up hardness.

Abstract: The invention provides a piston-cyclinder-assembly for a coffee brewing apparatus, the assembly comprising a cylindric cavity serving as a brewing chamber, a closing member mounted on the cylindric cavity at one end thereof, and a piston which can be displaced into and retracted from the brewing chamber at the other end. The piston is equipped with internal brewing water channels leading to the front face of the piston and connected to a brewing water connector. The closing member has plate-like shape and is fixed against movement in axial direction of the brewing chamber but is pivotally mounted near the cylindric cavity. To drive the piston into the cavity and to retract it, and to pivot the closing member, first and second stepping motors, respectively, are provided which are operatively connected to a control unit. Another embodiment is provided with a normal electric motor to drive the piston and with a pressure sensor. As soon as the piston exerts a preselected pressure on the coffee powder in the brewing chamber, the displacement of the piston is stopped.
