Abstract: ABSTRACT          An abrasive member for surfacing a workpiece by rotary abrasion under a flow of liquid, comprises a base and a plurality of abrasive segments protruding from the base.          The  abrasive  segments  are  shaped and arranged  in  spaced relation  to  one  another  so as  to  form  a  network  of intersecting primary and secondary channels,  the secondary channels  cooperating with the primary channels  to effect substantially complete scavenging of detritus by centrifugal drainage of waste liquid carrying the detritus through both the primary and secondary channels to the outer periphery of the abrasive segments.  Each abrasive segment has a planar working  surface  for  abrading contact engagement with the workpiece  and  a  bevelled  leading  edge  which  defines  a sloping abrasive surface permitting the abrasive segments to ride  up  over  surface  irregularities  protruding  from  the workpiece during rotation of the abrasive member,  whereby the  sloping  abrasive  surface cooperates with the working surface to grind the surface irregularities without causing chipping of the workpiece.

Inventor: KAWAKAMI SHIGERU
IPC: H04N7/045
Filed: 1992-06-15
Abstract: The present invention relates to a satellite television broadcasting station which receives waves from a satellite, selects a broadcasting station and obtains an FM demodulated video signal by passing a selected signal through the band-pass filter. In this satellite television broadcasting receiver, the video signal superposed with a large energy dispersion signal is inputted to the first clamping circuit at a, low level, to eliminate the energy dispersion signal. Thus, a room is provided in the dynamic range of the amplifier at the later stage and the DG and DP of the amplifier at the later stage are maintained at a satisfactory level by the second clamping circuit. As a result, even in the case of a satellite television broadcasting in which the level of the energy dispersion signal superposed on the video signal is large, distortion which occurs due to the nonlinearity of the amplifier can be reduced substantially so that the image can be reproduced on the screen in a satisfactory condition without an interference of flickering.

Filed: 1991-04-05
Abstract: A method of mutagenesis by which a predetermined amino acid is introduced into each and every position of a selected set of positions in a preselected region (or several different regions) of a protein to produce library of mutants. The method is based on the premise that certain amino acids play crucial role in the structure and function of proteins. Libraries can be generated which contain a high proportion of the desired mutants and are of reasonable size for screening. These libraries can be used to study the role of specific amino acids in protein structure and function and to develop new or improved proteins and polypep-tides such as enzymes, antibodies, single chain antibodies and catalytic antibodies.
