Patent EP-0650289-A1 (EP)
Inventor: SPAULDING KEVIN EDWARD C O EAS
IPC: H04N1/40
Filed: 1994-09-30
Abstract: Method and apparatus for generating a halftone image for a multi-level output device employing a dither matrix (18) generated by minimizing a visual cost function. The dither matrix is addressed by the least significant bits of a pixel address and the value supplied by the dither matrix is added (12) to the pixel value. The resulting sum is quantized in a quantizer (20) to produce the multi-level halftone value. 
     The added dither may also be multiplied (24,26) dependent on the input pixel value. The cost function is minimized by stochastic annealing or by a genetic algorithm.

Patent EP-0677370-A1 (EP)
Inventor: MCGREVY ALAN N
IPC: B29C45/28
Filed: 1995-02-13
Abstract: A manifold (15,16) is disposed within a pair of abutting pre-load mold plates (12) in a pre-load relationship. Fluid flowing through the manifold is heated by a first heater (24). The fluid is then divided into a plurality of passages (20a,20b,20c,20d,22a,22b) in the manifold. Pairs of passages have a back-to-back in-line relationship. A cylinder (38) between each pair of the in-line passages holds a pair of pistons (40a,40b) in the in-line relationship. Each piston (40a) in the pair has piston units (42a,4b) in an interdigitated relationship with piston units (42c,42d) on the other piston (40b) in the pair. Each pair of pistons is movable by pressurized fluid (e.g. air) between first and second positions. In the first position, each piston provides for the fluid (e.g. resin melt) flow through one of the passages to a pair of runners in the manifold. In the second position, each piston prevents the resin melt flow through the passages. A first heater (24) heats the resin melt flowing through the passages. A second heater (26) heats the resin melt flowing through the runners. Resin melt is prevented from leaking between the manifold and the mold plates even with temperature changes in the manifold as a result of the heating of the resin melt. This is accomplished by a pair of tongues (70,72), one rigid and the other resilient, extending from the manifold to the mold plate. In this way, fluid flowing into the manifold through one inlet exits through a plurality (e.g. 8) of gates without leakage after being heated at the passages and at the runners.

Abstract: In a magnetic recording and reproduction apparatus wherein signals are recorded with a ring-type magnetic head (10) to a magnetic recording medium (3) having axis of easy magnetization oblique with respect to a film normal of a magnetic layer (1) of the medium. A recording magnetic field generated by the magnetic head is asymmetric with respect to a center line of a gap (7) of the magnetic circuit, and the recording magnetic field in the magnetic layer around a leading edge (6) of the magnetic head is inclined at the same side as the axis of easy magnetization in the magnetic field in a normal plane of the magnetic layer including a direction of relative movement of the magnetic head to the magnetic recording medium when signals are recorded to the medium. Thus, signals can be recorded at a high density. Various types of magnetic head for generating asymmetric magnetic field are provided.
