Title: Process for activating catalyst for polymerizing propylene
Inventor: TAKAHASHI CHUROMU
IPC: B01J31/14
Filed: 1975-06-27
Granted: 1981-09-25
Abstract: A method is described for activating, prior to polymn., a catayst which produces cryst. polypropylene and highly inhibits the formation of amorphous polymer and elevates the stability of activity of the catalyst at the time of use.  The catalyst system consists of a dispersion of modified TiCl3 and an alkylaluminum chloride.  Thus, a catalyst dispersion comprising TiCl3 compn. (obtained from TiCl3.1/3AlCl3 activated by grinding in hexane and Bu2O at 60oC for 2 hr), Et2AlCl and diglyme in hexane to 700L was activated by continuously feeding propylene at TiCl3/hr at 25-30oC for 5 hr.

Granted: 1988-11-08
Abstract: A curve is approximated by a set of straight line segments. Numerically controlled machining is perfermed in the basis of numerical control data having a positional command of one block for each straight line segment.  Preprocessing is executed by prereading a positional command of a succeeding block while numerically controlled machining based on a current block is in progress.  An actual travelling distance (AD) to be traversed by a movable element is computed on the basis of the positional command of the succeeding block.  The magnitude of the travelling distance (AD) is compared against the magnitude of a separately entered permissible travelling distance (TD).

Abstract: The circuit for  compensating  the  vertical  and  horizontal sharpness compensates the input image signal which absolute  level is greater than the preset  one,  but  sets  the  deal  zone  with compensation against to the signal which absolute level  is  lower than the preset one. The  circuit  includes  an  adder  (100)  for adding the band-pass filtered Y signal (Xi)  to  the  coring  data (DC), a subtracter (200) for subtracting the coring data (DC) from the Xi signal, a logic circuit (300) for generating "0" when  both inverted output bits of the adder and the subtracter  are  "1",  a data selecter (400) for sending the output of the adder or that of the subtracter selectively according to the polarity of the  adder output, and a generator (500) for generating  the  output  of  the coring circuit (X0).

Abstract: The  paper  feeder  accessory  has  a  paper  feeding   tray sub- member with projector for guiding a paper tray received by the sub- member and a forward travel stopper preventing movement  of  a paper tray received the paper feeding tray sub-member in a copying mahine. A  paper  guide  underside  of  the  paper  feeding  tray sub-member in a coying machine. A paper  guide  underside  of  the paper feeding tray  sub-member.  A  slanting  position  member  is attached to a body of the copying  machine,  for  restraining  the lever and thus maintains the paper  feeding  tray  sub-member  ina slanting position relative to a horizontal plane. A device engages the lever with the slanting  position  member  and  comprises  two retaining cuts formed in the periphery of  the  slanting  position member.
