Patent CA-2025121-A1 (CA)
Inventor: FUJI HIROSHI
IPC: G11B7/005
Filed: 1990-09-12
Abstract: An  information  recording  and  reproducing  device having  an  automatic  gain  control  device  wherein  its amplification  degree  is  adjusted  according  to  an  AGC voltage varying with an amplitude of a reproduced signal.          The automatic gain control device has a holding circuit which holds  the AGC voltage  in  each of  recording and erasing operations,  and also holds  the AGC voltage  in reproducing an un-recorded area of information.  The AGC voltage is also used for determining an optimum recording condition for a recording medium.  Instead of the holding circuit, by installing a limiter circuit for limiting an amplitude of a reproduced signal,  and by the use of a transient response of the reproduced signal due to an ac coupling   situated  before   the limiter   circuit,   an appropriate amplification degree can also be obtained in the automatic gain control device.  Further, the limiter circuit which is disposed at a stage before a reproduction circuit  and  also  before  a  capacitor  having  the  ac coupling, may restrain influence of the transient response of the ac coupling given on the reproduced signal, thereby naking  it  possible  to  reproduce  a  signal  with  small amplitude   immediately   after   recording   or   erasing operation.

IPC: H01L41/09
Filed: 1992-02-05
Abstract: A driving apparatus for driving an object comprises a pair of piezoelectric elements, one of them being arranged on the one side of the object while the other of them on the other side of the object, and the respective electrode arrangement directions of the pair of piezoelectric elements being substantailly identical to each other, and a control circuit which applies a predetermined voltage across the outer electrodes of the pair of piezoelectric elements respectively, gives an equipotential to the inner electrodes thereof, and causes the pair of piezoelectric elements to drive the object by varying the value of the potential given to the inner electrodes. Hence, the increased amount of a voltage applied to one piezoelectric element is exactly identical to the decreased amount for the other so as to make the extended and contracted amounts of the piezoelectric elements on both sides of the object the same. Consequently, no useless stress is given to the piezoelectric elements for the prevention of the deterioration of the elements to implement a precise fine driving over a long period. <IMAGE>

Title: Removal of tissue
Inventor: ANIS AZIZ Y
IPC: A61F9/00
Filed: 1991-07-15
Abstract: To reduce damage to surrounding tissue while fragmenting some tissue, for example, not damaging the capsular wall while removing the lens during cataract removal surgery or not damaging artery or vein walls during bypass surgery while freeing the artery or vein to be transplanted, an incision is made for the insertion of a surface - discriminating, rotating, fragmenting tool (10) with blade portion (14). The blade portion (14) includes blades (17A and 17B) each of which is fastened to rotatable tubular shaft (18).  The tool (10) fragments and permits aspiration of the tissue without damaging the surrounding wall by fragmenting surfaces of higher inertia material but moving at a rate of speed and having openings between blades (17A and 17B) of such a size that the more integrated lower mass, more flexible and smoother tissue is moved away from the fragmenting zone and the higher mass, lower flexibility or rougher tissue is fragmented.

Title: Growth arrest of proliferating cells by transglutaminase inhibitors
Inventor: SAHASRABUDDHE C G
IPC: A61K31/00
Filed: 1990-12-13
Abstract: Proliferating B cells have a cytosolic Transglutaminase (TGase), which exhibits absolute requirement for Ca++ for its activity.  The molecular mass of this TGase is 85 kDa. A method for arresting the lymphocytic cell cycle progression in the G1-phase is described by the use of TGase inhibitors, monodansyl cadaverine (MDC) and 1-(5-aminopentyl)-3-phenylthiourea (PPTU). Reversal of this inhibition allows the lymphocytes to enter the S-phase of normal cell cycle progression. A monocytic cell strain exhibits arrest of cell growth and failure to enter S-phase upon treatment with TGase inhibitor.

Abstract: METHOD FOR MAKING, FILLING AND SEALING SACKS             ABSTRACT           The invention relates to a method for making, filling and  sealing  sacks  or  bags  from  a  tubular  film  web  of thermoplastic material preferably provided with side folds and printed in format print.  The leading end of the tubular film web is provided with a transverse weld; a section constituting an open sack is cut off from the tubular film web; the sack is then filled; and the open end of the sack is sealed by a transverse weld.  The invention seeks to provide a method where the sacks produced are always an appropriate size to be filled tight and full.  It is provided that the length of the formed tubular web section is varied,  corresponding to the filling level of the sack.  After making the transverse weld forming the sack, the tubular film web is advanced up to a printed mark.  The section constituting the sack is cut off by means of a separating cut without at the same time forming the transverse weld sealing the leading end of the tubular film web,  then the web is again advanced by a comparatively short adjustable length,  and the excess section of tubing is cut off and at the same time a transverse weld is formed.

Title: System and method for precision cleaning by jet spray
Inventor: PETERSON RONALD V
IPC: B24C1/00
Filed: 1992-09-03
Abstract: A system and method for precision cleaning of contaminants from the surface of a substrate, such as delicate surfaces or precision parts, utilizing streams of carbon dioxide snow or other cleaning gas.   The system includes an enclosed or sealed cleaning container in which at least one jet spray device is housed for directing a stream of cleaning snow against the surface to be cleaned.  During cleaning, the cleaning container holding the substrate to be cleaned is maintained under a vacuum or, optionally, at ambient pressure, filled with a clean dry gas.  The dislodged contaminants and spent snow are removed from the cleaning zone and disposed of or  recycled.    Cleaning  is  accomplished  by  pulsed application of the cleaning snow in combination with intermittent or continuous heating of the surface so that the surface is at an elevated temperature prior to and during each application of cleaning snow.  The jet spray devices which are utilized in the system are oriented so that the  cleaning snow streams contact planar surfaces at grazing angles of 5 to 45 degrees. When non-planar parts are being cleaned, the jet spray devices are adjusted to provide an angle of about 45 to 90 degrees.  Monitoring of the cleanliness of the parts is accomplished during the cleaning process, by a light scatter method or by a particle monitor and residual gas analysis of the exhaust gas or other analysis of the exhaust gas.   The system is particularly useful in removing contaminants  from the delicate surfaces or precision parts which are utilized in precision optical and electronic devices.
