Title: Method and device for collecting smoke in ladle refining device
Inventor: SUGAWARA MINORU
IPC: B22D37/00
Filed: 1982-11-19
Abstract: PURPOSE:To capture thoroughly leaking smoke without spoiling the nonoxidative atmosphere in a ladle at all in ladle refining wherein an inert gas is blown into the molten steel in the ladle by sucking and capturing the smoke leaking from the circumference of the ladle maintained under a positive pressure and a cover. CONSTITUTION:A cover 6 and hood 7 of a ladle refining device 15 are lowered by a hoisting device 9 to bring the cover 6 into contact with the top edge of a ladle 2. Nonoxidative slag 5 is charged from a feeding chute 12 into the ladle 2. The nonmetallic inclusion in a molten metal 3 is removed while an inert gas is blown from a porous plug 4 and an alloying agent, etc. are added from the chute 12. The leakage of smoke from the chute 12 is virtually obviated by the operation of dampers 11 in two upper and lower positions. On the other hand, the inert gas blown into the ladle is substd. with the air in the ladle 2 and leaks to the entire circumference from the clearance between the ladle 2 and the cover 6. However, the flue part of the upper and lower plate materials of the hood 7 opens by enclosing the entire circumference of the cover near the above- mentioned clearance and therefore the leaking smoke is sucked through the same and flows through a smoke collection duct 13 to a dust collector.

Title: Image pickup signal processing unit
Inventor: SASAKI TAKU
IPC: H04N9/07
Filed: 1990-07-31
Abstract: PURPOSE:To realize a high quality image pickup signal processing unit with less false signal by using only a luminance signal subjected to offset sampling so as to implement interpolation and synthesis. CONSTITUTION:A luminance signal processing section 21 accesses a Y memory 18 to apply interpolation and gamma conversion or the like to form a luminance signal. F91' example, in order to interpolate a picture element Y32, it is desirable to adopt the relation of Y32=1/4[Y31+Y22+Y33+Y42]. This is implemented by setting a part without sampling to 0 as to a data stored in the memory 18 and a specific filter applies convolution calculation. Moreover, a color signal processing section 22 accesses properly a Y memory 18, an R memory 19 and a B memory 20 to generate two color difference signals R-Y, B-Y. Thus, the image pickup signal processing unit with very high quality having no false signal in the luminance signal is realized.

Abstract: PURPOSE:To perform the access composition of plural sequences of input signals through a simple circuit by delaying and inserting a conventional clock within an excessive time obtained by slanting and compressing the timing of the clock of a main-system input signal and composing a slave-system input signal. CONSTITUTION:The main-system input signal 1Na is stored in a register 1a temporarily and sent out from a terminal A of a selector MPX4a to an output terminal OUT1 by the application of a clock signal CLKa. The CLKa is supplied to a main clock timing compressor 2, which slants and compresses the timing different in every order of the clock to input a deformed clock CLKa1 to an MPX4b, whose output is sent out from a terminal OUT2. The slave-system input signal 1Nb is stored in a register 1b and applied to a terminal B of an MPX4a by a clock CLKb. The CLKb is delayed and inserted by a clock controller 3 within the excessive time obtained by slanting and compressing the CLKa1 and terminals B of the MPXs 4a and 4b are selected to output the signal 1Nb from the terminal OUT1 and the CLKb from the terminal OUT2; and the signals 1Na and 1Nb are outputted synchronously by the composite clock obtained from the OUT2.

Title: Surface protective film
Inventor: TAKAHASHI YASUSHI
IPC: G02B5/30
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a surface protectively film not peeling from an optical member by an environmental change in such as temperature or humidity, satisfying fundamental performance allowing peeling and separation for the optical member without leaving an adhesive when peeling, and allowing easy peeling and separation by hand or a machine without giving damage to the optical member or peeling from a liquid crystal cell even after heating such as a aging. SOLUTION: This protective film 1 adheres to and covers the surface of an optical member 2. On the basis of a 180 deg. peeling test at a peeling velocity of 300 mm/minute, an adhesive force of the protective film 1 to the optical member 2 at normal temperature after they are left in 80 deg.C atmosphere is below 1.3 times the adhesive force when they are left in normal temperatures. Thereby, even if heating such as aging or the like is applied, an increase of the adhesive force is small to easily peel and separate the protective film 1 from the optical member 2.
