Title: Method and apparatus for cleaning workpiece surfaces and monitoring probes during workpiece processing
Inventor: HOLZAPFEL PAUL
IPC: B24B49/00
Filed: 1998-02-06
Granted: 2001-05-30
Abstract: The present invention provides methods and apparatus which permit the in-process, in-situ, substantially real time measurement of the actual thickness of a surface layer of a workpiece, e.g., a semiconductor wafer. A probe is disposed proximate the outer perimeter of a polishing pad on a CMP table such that the probe establishes optical contact with the wafer surface as a portion of the wafer extends beyond the outer perimeter of the polishing pad. A reflected signal received by the probe is analyzed to calculate the thickness of the surface layer. Alternatively, the reflective characteristics of the semiconductor layers may affect the nature of the reflected signal; changes in the reflected signal can be detected to indicate when a metallic layer has been removed from an oxide layer. In accordance with another aspect of the present invention, a nozzle assembly having a plurality of fluid outlets may be provided to apply a stream of deionized water at the surface under inspection to thereby remove excess slurry and debris from the local region of the workpiece being inspected. A second fluid nozzle may be provided to apply a stream of deionized water to the tip of the probe tip to thereby clean the probe tip between endpoint detection cycles. The nozzle assembly may also include a third fluid nozzle for applying a stream of nitrogen gas to thereby deflect debris away from the probe tip during the endpoint detection procedure and a fourth fluid nozzle for applying a stream of nitrogen gas to thereby remove water and debris from the probe tip during the endpoint detection procedure.

Abstract: The invention relates to an automatically and continuously variable transmission for changing the velocity of a driven shaft relative to the velocity of a drive shaft. The transmission includes three epicyclic trains, namely an input train, a control train and an intermediate train. The input train includes an element driven by the drive shaft and another element connected to the driven shaft. The control train is a high ratio train including a planetary gear system, the planet-carrier of which is driven by an electric motor of variable velocity and low power, of the order of 1 percent of the power to be transmitted from the drive shaft to the driven shaft. A first sun-wheel of the planetary gear system is connected to the third element of the input train and a second-sun-wheel is connected to an element of the intermediate train, the two remaining elements of which are respectively connected to the input train and to either of the drive or the driven shafts.

Granted: 1994-03-17
Abstract: The object of the present invention is a product based on a trans-retinoic acid (tretinoin) and azelaic acid combination having depigmentating effect and, more generally, antiphotoageing effect. After clinical and instrumental comparative analysis (clinical and photographic reports and skin mould profilometry), the action on physiological and/or photoinduced skin ageing obtained with the combination of the invention has been compared with the one noticeable after the treatment with azelaic acid or retinoic acid only. Better results were obtained using the azelaic-retinoic combination. The depigmentating action of the combination is superimposable to the one observed by using separately the two active ingredients, but it can be achieved in a surprisingly shorter time (from six to three months).

Title: Convergent solar energy collector - presents planes of reflectors constantly at right angles to incident solar radiation
Inventor: VIGOUREUX FRANCIS E
Filed: 1976-09-22
Granted: 1985-05-08
Abstract: A convergent device for collecting and using solar energy comprises an arrangement of mirrors, fixed in its geometry, but capable of being oriented in all directions. The mirrors are stabilised according to angles calculated to give a convergence of the incident solar radiation. The device precisely follows the apparent motion of the sun and presentsits surface place constantly at right angles to the solar radiation. The stable position of each reflector is calculated to receive the radiation in such a way that the angle of reflection equals the angle of incidence. The reflected radiation becomes incidental radiation on the surface of a counter-reflector which reflects it towards the focus of convergence at a point beneath the base of the device, around a point on the axis perpendicular to its plane. The stable arrangement of the reflectors and the counter-reflectors is the same on all the secant planes. The geometrical arrangement of the plan of the device is arbitrary and may be a polygon or a circle. Appts. gives a yield, relatively to the amt. of surface exposed, much higher than those of existing devices. The only limiting factor is the amount of sunshine of the locality and the device can be installed anywhere provided there is sufficient sunshine, whether there is wind or not and irrespective of the terrain or location (on roof, etc).

Title: Blanks magnetic clamping plate
Inventor: VERNIKOV ARKADY YAKOVLEVICH
IPC: B23Q/
Filed: 1985-04-01
Granted: 1988-01-14
Abstract: The grooves on a plate surface separate the poles of the magnetic system, and the side of the plate facing the source of the magnetic field exhibits additional grooves which are offset from the other grooves. The spacing from the bottom of the groove to the surface of the plate, and the distance separating the main and the additional grooves as well as the overlap of the main and additional grooves are equal to each other. The blanks are placed on the plate and the coils are connected to the d.c. source ensuring a different polarity in adjacent cores. The magnetic flux generated by the coils passes through the base, cores, plate and the blank, the path determined by the geometry of the plate and by the size of the blank. If the blank overlaps two poles, the additional grooves prevent flux closure through the plate, while in the case of a small blank covering only one pole, the additional grroves (7) provide a path of two fluxes through the blank.

Title: Secrecy guaranteeing electrical signal coder-decoder - uses similar drifts generated locally at transmitter and receiver which are synchronised
IPC: H04K/
Filed: 1973-02-16
Granted: 1979-12-20
Abstract: The system guarantees the secrecy of the signal during its transmission between a transmitter and receiver. At the transmitter coding is obtained by imposing a reference frequency. This frequency is used to carry out transposition of the signals frequency spectrum. A continuous drift of pseudo aleatory character in a very long period is produced by means of a locally generated analogue signal. The decoding at the receiver is obtained by imposing a reference frequency which is used to effect frequency transposition having the same value as that of the transmitter. A drift having the same characteristics as the transmitter is produced from an analogue signal generated locally and synchronised with that generated at the transmitter.
