Patent DE-19648408-A1 (DE)
Title: Piston pump for supplying anti-lock braking system for vehicles
Inventor: ALAZE NORBERT
IPC: B60T8/40
Filed: 1996-11-22
Abstract: The piston pump (10) has an outlet valve (38) in the form of a no-return valve. There is a relief aperture (66) in the valve chamber (44). It is located eccentrically on the same side as the valve outlet aperture (64) in the region of the valve ball (56). The flow round the valve ball which builds up when the outlet valve is opened acts through the outlet aperture and the relief aperture to divert the valve ball radially in front of the outlet aperture, where it remains in a stable open position.

Title: Method for obtaining increased spark-length in IC engine
Inventor: SCHWARZ SIEGFRIED
IPC: H01T13/24
Filed: 1997-01-03
Abstract: An increase in the electric spark in an IC engine occurs when the electrode distance is immediately increased after the first high voltage strike. With the ignition, a somehow special force moves one of the two electrodes from the other. The centre electrode 93) is arranged in conventional fashion and the earth electrode (4) is electrically connected with the spark plug thread 97). The earth electrode is designed to be movable, being moved by the electromagnet (5). This is in a series circuit for the primary current of the spark coil.  During primary current flow, the electrode distance is small. When the primary current is interrupted and with the smallest gap the spark jumps across the gap and with the duration of the spark, the earth electrode is moved in spring-controlled fashion so that the spark is increased.

Patent DE-19710203-A1 (DE)
Title: Charging operation controlling method for contact charger of copier, laser printer, facsimile, LED printer
Inventor: KYUNG MYUNG-HO
IPC: G03G15/02
Filed: 1997-03-12
Abstract: The method involves supplying a negative charging voltage of specific level to a contact charger for a first time interval corresponding to one initial rotation of a photosensitive drum. Then, the supply negative charging voltage is stopped. A negative developing bias voltage which is lower than the surface voltage of the photosensitive drum is supplied to the developing unit for a second time interval before stopping the rotation of the photosensitive drum. The negatively charged toner particles scattered in the developing unit and adhering to the photosensitive drum move from the photosensitive drum to the developing unit due to the electrical potential difference between the surface of the photosensitive drum and developing unit. The positively charged toner particles move from the contact charger to the photosensitive drum and to the developing unit due to the negative developing bias voltage.

Title: Flatness measurement and analysis method
Inventor: UEKI NOBUAKI
IPC: G01B11/30
Filed: 1998-03-12
Abstract: The method involves selecting different pairs of plates out of three pairs, three times sequentially. The pairs are arranged with a predefined intermediate gap. The difference between the opposing surfaces is measured in two dimensions. The shape of the measurement surface of each plate is determined by processing the results of the three sets of measurements. The difference is measured with one plate at a defined angle with respect to the other and then with both plates rotated through 90 deg  with respect to each other. A relationship is produced relating the difference between the opposing surfaces in the two positions with predefined degree of symmetry series polynomials approximating to a shape of the surface of the measured plate. The shape of the surface of each measured plate is determined by processing the pairs of relationships.
