Abstract: A mixed mode controller (100) for use with a motor having a mechanism (110, 114) for generating a command signal to operate the motor and a first circuit (104) for adjusting the gain of the command signal to provide high speed operation.  A second circuit (102) is provided for converting the command signal to a drive signal to excite a winding (106) and to damp the motor.  In a preferred embodiment, a step rate signal introduced into the motor controller (100) is operated upon by  an accumulator (110) and a memory (114) to generate a voltage command signal.  The motor controller (100) includes a low bandwidth current control feedback loop (104) utilized to adjust the gain of the voltage command signal by comparing a command motor current and an actual motor current in a summer circuit (126).  The feedback loop (104) provides for automatic gain control of the voltage command signal for yielding  high speed operation.  The gain-adjusted voltage command signal is thereafter applied to a bipolar voltage driver (102) having high motor damping characteristics.  The voltage driver (102) is utilized to control the application of a bus voltage to the motor winding (106) of a stepper motor via a transistor control logic circuit (148).  Also included is a time constant correction network (138) for accelerating the settling of variations in the motor current to steady state.   Thus, the correction network (138) ensures a rapid response to changes in the commanded motor current.

Title: Method of manufacturing an integrated circuit and integrated circuit obtained by this method
Inventor: WALKER ANDREW JAN
IPC: H01L21/8247
Filed: 1993-10-04
Abstract: If the process were to be changed for optimizing the injection of hot electrons into the channel of the memory transistor in the manufacture of an integrated circuit comprising an embedded EPROM, this could lead to degradation of the transistors in the logic, in particular in the case of channel lengths below 1 µm. To prevent this, a process is presented by which the non-volatile memory is optimized without the properties of the logic being affected by this. For this purpose, according to the invention, a first series of steps is performed in which first the floating gate is defined, followed by the source/drain implantation and a side-wall oxidation for obtaining an oxide spacer on the sides of the floating gate. During these steps, the region of the logic to be formed is uniformly protected against implantation and oxidation by the same poly layer from which the floating gate is made. Then, in a second series of steps, the usual CMOS process is carried out whereby first the gates of the transistors are formed, followed by the necessary source/drain implantations.

Title: A method of generating high carotenoid-producing microorganisms, microorganisms obtained by the method and a process for producing carotenoid-containing cells or cell parts or purified carotenoid
Inventor: VILLADSEN INGRID S
IPC: C12P23/00
Filed: 1992-06-15
Abstract: High carotenoid-producing, in particular astaxanthin-producing, microorganisms are generated by treating cells of a carotenoid-producing microorganism strain with a mutagen, culturing the mutagenized cells in the presence of a phytoene dehydrogenase inhibitor to reduce the level of carotenoid production of all the cells, and selecting a mutant cell or colony showing increased carotenoid coloring compared to the background. In particular, the carotenoid-producing microorganism is Phaffia rhodozyma, and the cells are grown to the late stationary phase before they are treated with the mutagen. The obtained microorganisms can be grown to obtain a biomass containing the carotenoid in an amount of at least 1600, preferably at least 1900 µg/g dry weight. When culturing a carotenoid-producing microorganism to produce carotenoid-containing microbial cells or purified carotenoid, particularly high yields of carotenoid can be obtained by growing the cells to the haploid phase before they are harvested or further treated. Still higher yields may be obtained by using a culture medium containing peroxisome-inducing substances.
