Title: Switched power regulator
IPC: H02M1/00
Filed: 2009-10-27
Abstract: Methods and apparatus for control of DC-DC converters, especially in valley current mode. The DC-DC converter is operable so that a low side supply switch may be turned off, before the high side supply switch is turned on. During the period when both switches are off the current loop control remains active and the change in inductor (L) current is emulated. One embodiment uses a current sensor for lossless current sensing and emulates the change in inductor current by holding the value of the output of the current sensor (ISNS) at the time that the low side switch turns off and adding an emulated ramp signal (VISLP) until the inductor current reaches zero. Embodiment employing a pulse-skip mode of operation based on a minimum conduction time are also disclosed. The invention enables a seamless transition from Continuous Conduction Mode the Discontinuous Conduction Mode and Pulse Skipping and provide converters that are efficient at low current loads.

Title: Reusable electrophotographic element and process for preparing that element
Inventor: DE PUTTER JAN ALEXANDER
IPC: G03G5/087
Filed: 1981-10-27
Granted: 1985-08-14
Abstract: A reusable electrophotographic element comprising a photoconductive layer containing sensitized zinc oxide particles and first and second binding agents that are incompatible is produced by employing as the first binding agent a macromolecular compound that has a higher affinity to zinc oxide than the second binding agent, is largely deposited on the zinc oxide, has an average molecular weight of at least 12,000 and is present in the photoconductive layer in an amount of 1.5 to 9% by weight calculated on the zinc oxide, with the second binding agent present in substantially larger amount. The photoconductive layer is formed of agglomerates of zinc oxide particles substantially enveloped in the first binding agent, which agglomerates have a diameter of between 2.5 and 6  mu m and are stuck together by portions of the second binding agent, thus providing a substantially porous photoconductive layer having a negative charge density of at most 1 m Coulomb per m2. The photoconductive layer is produced by mixing together the zinc oxide, any desired dye sensitizer, and solutions of the binding agents in one or more volatilizable solvents, applying a layer of the resulting dispersion to a substrate suited for electrophotography and drying the applied layer. The electrophotographic element has a very high resistance to both electrical and mechanical influences, thus being suited for long service life in an electrophotographic copying machine.
