Title: Method and apparatus for removing cutting burr sticking to lower surface of slab
Inventor: HASEBA NOBUHISA
IPC: B23K7/06
Filed: 1983-04-09
Granted: 1986-06-18
Abstract: The arrangement is intended for removing the ridge of metal(4) remaining at the underside of the flame-cut edge of a longitudinally cut slab(2). The slab is placed and clamped with its underside on a horizontal roller track(6), with the edge parallel to the track transport direction. At least one cutting unit (A) below the track has a blade carrier(11) and is lifted(21,9) to bring the blade into contact with the underside after which the blade is horizontally moved(8) in a direction at right angles to the edge in order to remove a ridge portion equal to the effective blade length. The slab is released and moved by an amount equal to this length and the operation repeated until the entire ridge is removed.

Title: Trilevel sand castle pulse encoder
Inventor: HETTIGER JAMES
IPC: H04N9/44
Filed: 1984-12-13
Granted: 1992-10-08
Abstract: In a color TV receiver incorporating automatic kinescope bias (AKB) control circuits, a first train of monolevel pulses with timing suitable for retrace blanking purposes and a second train of monolevel pulses with "backporch" timing appropriate for burst gating purposes are applied to a circuit serving to generate at a first terminal a train of bilevel pulses exhibiting a first voltage level during periods of overlapping of the pulses of the first and second trains, and exhibiting a second, lesser voltage level during the remaining, non-overlapping portions of the pulses of the first train. A resistor interconnects the first terminal with a second terminal. A keyed voltage source, responsive to a third train of monolevel pulses timed to indicate recurring kinescope bias control intervals, develops a voltage of a third level, intermediate the first and second voltage levels, at the second terminal during the recurring control intervals. The keyed voltage source exhibits, during the control intervals, an output impedance significantly lower than the impedance exhibited by the interconnecting resistor. During periods intervening successive ones of the control intervals, the voltage source is effectively disabled and exhibits an output impedance significantly higher than the impedance exhibited by the resistor.

Abstract: The method for producing an oil/water sunscreen  cosmetic  is charcterized by (a) adding  4.0-16.0  wt.%  polymer  powder  to  a mixture  of  5.0-10.0  wt.%  polyhydric  alcohol,   0.3-0.5   wt.% antiseptics and 0.1-0.3 wt.% neutralizer as an equeous  component, and 15-25 wt.% fat-soluble component  and  1.5-2.5  wt.%  nonionic surfactant as an oily component,  (b)  agitating  the  mixture  at 10000-12000 rpm for 5-10 min, and  (c)  mixing  the  mixture  with 0.1-0.15 wt.% stabilizer. The powder is obtained by  adsorbing  an ultraviolet-intercepting agent to a  methacrylate  copolymer.  The sunscreen cosmetic has an improved stability and water-resistance.

Abstract: The cystalline  thin  film  (4)  of  lanthanum  aluminate  is prepared  by  (a)  maintaining  the  temperature  of  the  silicon substrate (1) at 100-400 deg.C, (b) flowing the mixture gas  which has the ratio of argon to oxygen, 3:1 by the pressure of 10 mTorr, (c) transporting the atoms of lanthanum aluminate  ceramics  as  a sputtering target, retaining the distance between atoms  of  20-50 mm, to the surface of the silicon substrate (1), (d)  forming  the amorphous  lanthanum  aluminate  thin  film  (3)  on  the  silicon substrate, (e) elevating the temperature to 900-1200  deg.C  by  4 deg.C per min. and soaking for 30 min. - 2 hrs. and cooling to the normal temperature by 0.5-1 deg.C  per  min.,  and  (f)  supplying oxygen into the horizontal tube furnace.
