IPC: B65G47/26
Filed: 1991-02-28
Abstract: A B S T R A C T      A roller conveyor in which articles are supported by idler rollers carried by a main frame and conveyed as the idler rollers are driven into rotation.  A plurality of first idler rollers are arranged in one of two side frames of the main frame.  A plurality of second idler rollers capable of supporting articles in pair with the first idler rollers are arranged in the other side frame. Driving force for conveying articles is given to the first idler rollers only.  The fact that first idler rollers and second idler rollers are separately arranged at opposite sides assures that the first and second idler rollers are of short and light construction.

Abstract: An  optical  head  comprising  a  diffracting  element having two tracking diffracting regions  separated by a division line extending in a direction corresponding to a track direction of a recording medium, and one focusing diffracting region separated from the tracking diffracting regions  by  a  division  line  extending  in  a  direction corresponding  to  a  radial  direction  of  the  recording medium.  The  optical  head  further  comprises  a  light receiving  element  having  two  tracking  light  receiving regions for receiving diffracted lights produced in the tracking diffracting regions, and two adjoining focusing light receiving regions for receiving a diffracted light produced   in the   focusing  diffracting  region.   The diffracted  light  produced  in  the  focusing  diffracting region  always   has   a  substantially  constant   light intensity, even when a tracking error occurs. As a result, an offset can be prevented from occurring in a focus error signal by finely adjusting the diffracting element.

Abstract: A low profile power drive assembly (10) for conveying articles along a conveyor path includes one cylindrical  roller  (22)  supported on an eccentric shaft (32).   A first drive motor (26) and a second drive motor  (26')  are operatively connected to the roller  (22)  for synchronously rotating the roller (22).  The free state position of the roller (22) is in a lower retracted position.  When the first (26) and  second  (26')  drive  motors  apply  simultaneous driving torque to the roller (22), the roller (22) rises vertically to a lifted operative position to engage the underside of an article to be conveyed.  A clutch (38)  is disposed inside the roller (22)  for controlling the upwardly normal force applied to the underside  of  the  article  being  conveyed.    The assembly  (10)   is  disposable  within  a  standard rollerway  (12)  in  a  conventional  aircraft  cargo conveyor system.

Abstract: A sensor assembly for an in vivo physiological pressure measurement has a member with a distal end to ease placement of the catheter sensor assembly in vivo.   A passage  is  preferably  in  an  intermediate part  of  the member  and  is  open but  covered by a pressure responsive sensor sealing the passage.  The sensor has a first side away from the intermediate part for exposure to in vivo physiological pressure and a second side  in fluid communication with the passage.  A pressure connecting means for inhibiting liquid    communication    located    between    the physiological pressure and the passage  is  arranged for selectively connection therebetween so that when connected the pressure on the first and second sides of  the  sensor  can  be  substantially  equalized.   A control ex vivo makes the selective connection of the second   side   of   the  pressure   sensor   and  the physiological pressure.  A method for rezeroing an in vivo pressure sensor has  the steps  of obtaining a signal from the first side of the sensor at distal end, using a pressure substantially equal to the in vivo  pressure  and  applying  that  pressure  to  the second side of the sensor.

Filed: 1991-10-02
Abstract: Abstract of the Disclosure:          The tension frame of conventional racquets produced according to the single or double tube process are hollow on the inside or filled with a light foam. In terms of sufficient rigidity, such racquets must have a minimum width in order to be able to withstand playing action. The novel racquet is to be produced such that the frame width can be further reduced. The frame height of the novel racquet transversely to the plane in which the strings are disposed is greater than the frame width in the plane of the strings. The cross section of the frame is solid in its center section and has, formed in its narrow vertically opposite ends, a channel-like hollow space each. It is thus possible to even further reduce the frame width, for example in order to achieve a more slender construction and better aerodynamic properties.

Abstract: A semiconductor device having a reflecting layer consisting of unit semiconductors each consisting of two or more semiconductor films of different compositions. The thickness of the unit semiconductors varies continuously or in steps in the direction of thickness of the reflecting layer, preferably decreases in the direction toward the light incidence surface of the layer. For example, the reflecting lever has a varying-thickness portion whose unit semiconductors have a continuously varying thickness, and may include an iso-thickness portion whose semiconductors have the same thickness. The composition at the interface of the adjacent films preferably changes to mitigate a lattice mismatch which causes crystal defects of the layer.

IPC: H04N19/94
Filed: 1991-11-06
Abstract: A quantizer, with quantization control that is sensitive to input signal characteristics and to output buffer fullness responds to an input signal that is divided into blocks and DCT transformed. The transformed signal is analyzed to develop a brightness correction and to evaluate the texture of the image and thechange in texture in the image. Based on these, and in concert with the human visual perception model, perception threshold signals are created for each subband of the transformed signal. Concurrently, scale factors for each subband of the transformed signal are computed, and a measure of variability in the transformed input signal is calculated. A measure of the fullness of the buffer to which the quantizer sends its encoded results is obtained, and that measure is combined with the calculated signal variability to develop a correction signal. The correction signal modifies the perception threshold signals to develop threshold control signals that are applied to the quantizer. The scale factors are also applied to the quantizer, as well as a global target distortion measure.
