Patent EP-0364259-A2 (EP)
Inventor: EPLER JOHN E
IPC: C30B33/08
Filed: 1989-10-12
Abstract: In situ  evaporation of selected surface regions or layers of compound semiconductors is accomplished, without breaking the growth system environment by employing photo-­induced evaporation enhancement in chemical vapor deposition epitaxy. Intense radiation from an energy source (27) desorbs or causes evaporation of consecutive monolayers of atoms or combined atoms from the surface crystal (34) by thermal evaporation. The desorbed atoms from the growth surface are removed atomic layer by atomic layer in a fairly uniform and systematic manner, and may be characterized as "monolayer peeling", resulting in a morphology that is sculpturally smooth and molecularly continuous. In this sense, the method of this invention is analogous to erasing or etching crystal material and is the antithesis to laser deposition patterning, wherein erasure after growth or reduced rate of growth during growth provides "negative growth patterning". This patternable negative growth process is coupled with a positive growth process for selectively thinning regions of semiconductor layers in three-­dimensional crystal structures, limited only by the functional capabilities of the growth reactor. Selective monotonic increasing and decreasing film thickness  in situ  can be accomplished while beam illumination (26) remains stationary for a predetermined period with exposure of the growth surface accomplished through a patterned mask or, alternatively, while the beam spot or multiple beam spots are modulated and scanned across the growth surface of the film.

The poles of the magnetic generator (29) are angularly spaced about the axis (RR) by an angle such that the variations of magnetic flux generated through the coil (40) by rotation of the magnetic generator (29) have a cycle ratio which is other than unity.

Abstract: This invention is a process for preparing a polymer which comprises contacting pure dicyclopentadiene with a pure tungsten catalyst complex, such as WCl₃(2,6-diisopropyl­phenoxy)₃, when tributyl tin hydride or triphenyl tin hydride is used as the activator for the polymerization. This process affords a method of polymerization of dicyclopentadiene in which the mixture gels slowly without the use of a rate moderator at 80°C. (in from about 15 seconds to as much as two minutes or more) and furthermore cures quite slowly (in about 3-6 minutes). This delay makes these compositions particularly applicable to reaction injection molding processes. Moreover, both the tungsten complexes and the tin activator compounds employed in this invention are relatively insensitive to oxygen and water.

Abstract: An improved near infrared spectrophotometer is disclosed which reduces wave shift errors arising from hot spots in a light source. A ground quartz plate (21) uniformly diffuses radiation from the light source (12) to evenly illuminate the entrance slit (18) for a diffraction grating (20). Radiation emerges from the entrance slit with a uniform angular intensity distribution and is dispersed into a spectrum by a reflecting diffraction grating (20) towards an exit slit (26). A narrow wavelength band of radiation passes through the exit slit to illuminate a sample (28). Because the entrance slit is uniformly illuminated, without regard to variations in radiation intensity due to hot spots in the source, wave shift errors in the reflectivity measurements for the sample are reduced.

Abstract: A brake control apparatus is described that maximizes the braking efficiency of an under-damped actuator, such as a motor-driven linear screw (14). When an incipient lock condition is detected, the apparatus determines the optimal brake pressure, relieves brake pressure and measures the duration of the pressure release. When the wheel is approaching recovery, but has not yet substantially recovered, the apparatus holds brake pressure constant at a value calculated to represent the amount of pressure remaining at the wheel brake. This calculated hold value is based upon the measured optimal pressure and the measured release duration, and allows the wheel to continue to reaccelerate towards recovery while preventing unnecessary pressure relief. Once the wheel recovers, the apparatus reapplies brake pressure to a substantial fraction of the optimal pressure without over-exciting the actuator and over-shooting the desired pressure.

Abstract: An integrated circuit cell module for performing precise time measurements for use in applications such as disk drive controllers. The combination of the cell module and a hard disk controller chip creates a complete hard disk controller in a single chip without the need for external analog components normally required for classic phase lock loop hard disk controllers. A problem in designing such a unified chip is that it must be digital in nature. Therefore, the maximum resolution with which signals generated by the disk drive (Rddata signals) can be measured and signals generated by the controller for writing to disk (Wrdata signals) can be generated is dependent on the clock which drives the controller chip. In hard disk controllers, the data rate is such that the minimum distance between adjacent Rddata or Wrdata pulses is approximately 100 ns which would require an oscillator having a speed which would be impractical in a design. This problem is solved using standard CMOS gates to measure the distance between a reference clock and the Rddata pulse to 2 ns. accuracy. This measurement is provided as a binary number to the hard disk controller which uses this information along with the measurement for an adjacent pulse to determine the distance between adjacent pulses (cell time) to within 2 ns. For generating Wrdata pulses, a binary number is input which defines the distance to be delayed from the reference clock. This delay can be any multiple of 4 ns. over the period of the reference clock. Thus, it is possible to create distances between adjacent Wrdata pulses to within 4 ns. increments.

Abstract: The drilling device for making undercut drill holes in subsoil has a guide sleeve (2) and an eccentric bush (4) rotatable relative to the guide sleeve. A torsion spring (6) is arranged between the guide sleeve (2) and the eccentric bush (4). When the eccentric bush (4) rotates relative to the guide bush (2), the torsion spring (6) is tensioned. As a result, the drive shaft (8) with the cutting head (9) is at the same time put into an eccentric position and a recess is produced in the wall of the drill hole. In the process, a locking mechanism acting on a tooth system (2a) prevents the guide sleeve (2) from rotating with the eccentric bush (4). Once the maximum eccentricity of the drive shaft (8) is reached, the locking mechanism is released and the guide sleeve (2) is rotated together with the eccentric bush (4) via an eccentric drive. As a result, the cutting head (9) creates an encircling undercut in the wall of the drill hole. After a complete revolution, the torsion spring (6) can be relieved again and the guide sleeve (2) can rotate relative to the eccentric bush (4) so that the drive shaft (8) again moves into the concentric position.
