Patent DE-19731752-A1 (DE)
Title: Method of controlling illumination for electric photographic device
Inventor: MARUO SEIJI
IPC: B41J2/44
Filed: 1997-07-23
Abstract: The method controls illuminations for the device using a three level developing process. The occurrence of an edge effect is suppressed by weakening an inverse electric field which generates the edge around a section of an image using an illumination controller. Information based on the edge characteristics may be used as judgement information for setting the illumination control. Only one level of the electric potential of the surface is used as a value for the illumination control. Ferrite and magnetite may be used as a base material of the carrier.

Patent DE-19811868-A1 (DE)
Title: Delay circuit especially for testing semiconductor components
Inventor: SATO MASATOSHI
IPC: H03K5/135
Filed: 1998-03-18
Abstract: The delay circuit generates a delay time which is longer than a cycle time of a reference clock while the resolution of the delay time is less than a cycle time of the reference clock. The circuit has a logic delay circuit to generate a transmission signal with a delay time which corresponds to a  common multiple of a cycle time of a reference clock. A frequency divider changes a frequency of the reference clock to generate the clock signal fed to the logic delay circuit. A flip-flop circuit delays an incoming signal by a time period of the reference clock. A synchronisation circuit receives an output signal of the flip-flop and generates a delayed logic signal in synchronisation with the reference clock. A decoder receives the transmission signal from the logic delay circuit and selectively supplies the transmission signal to the flip flop or the synchronisation circuit. A fine delay circuit adds a fine delay time which is smaller than a cycle of the reference clock to the delayed logic signal of the synchronisation circuit.

Patent DE-19822436-A1 (DE)
Title: Operating hydraulic press the force drop during changeover from the fast motion to the forming motion is reduced
Inventor: BRECKNER MANFRED
IPC: B30B15/16
Filed: 1998-05-19
Abstract: Pressure is released in a cylinder chamber so the pressure in the opposing chamber produces additional force. During the passage of the press tool through the first section of its stroke, the pressure medium from the cylinder chamber serving for press opening is fed into the cylinder chamber serving for press closure.  The pressures in the cylinder chambers are chosen so the forces acting on the piston areas mutually cancel out. Before the start of the forming operation the pressure in the first cylinder chamber is released. As a result, the pressure in the second (opposing) cylinder chamber produces an additional force tending to form the workpiece.  The claimed hydraulic press incorporates a control unit (10) and cylinders (3, 4) whose opposing chambers are connected with one another via valves (27, 28).
