Title: Picture processing system
Inventor: MARUYAMA TSUGITO
IPC: G06K9/46
Filed: 1982-06-18
Abstract: PURPOSE:To extract coarse profile in high speed with a simple constitution, by processing a contrast picture in the unit of picture elements, and using a smoothing operation section and a secondary differentiation operating section comprising a space filter. CONSTITUTION:An analog picture signal in the unit of picture elements inputted from a TV camera 1 is converted into a picture signal of a multiple level at an A/D converter 2 and inputted to the smoothing operation section 3, which uses the space filter comprising a data shift circuit 3-1 storing a prescribed length of data, a multiplication circuit 3-2 multiplying the stored data with a set weight number, an adder 3-3 summing the result all together, and a divider dividing the level increased by the addition so as to be brought into a suitable range, and reduces noise superimposed on the picture data and inputs the result to the secondary differentiation circuit 4. The circuit 4 uses a similar space filter, emphasizes a sudden change in the lightness and inputs the result to a pole extracting circuit 5. The circuit 5 extracts the pole of the picture from the input signal and set it to a picture memory 6. Thus, the profile of the picture is obtained in high speed in synchronizing with the camera 1.

Title: Production of 3-ethyl-1-olefin
Inventor: NAKAGAWA KANJI
IPC: C07C2/24
Filed: 1995-04-28
Abstract: PURPOSE: To obtain the subject compound useful as a raw material for polyolefins by bringing a catalyst excellent in low-temperature activity and reaction selectivity into contact with propylene followed by codimerization when conducting codimerization between ethylene and an olefin. CONSTITUTION: This compound is obtained by bringing a catalyst prepared by carrying an alkali metal on a granular carrier composed of an anhydrous potassium compound and carbon (e.g. graphite) into contact with propylene at 130-170 deg.C under a pressure of 20kg/cm<2> G for 2-50h followed by codimerization between ethylene and a >=4C olefin (e.g. 1-butene) under a pressure of normal pressure to 100kg/cm<2> G at 70-120 deg.C in the presence of the above catalyst. The amounts of the alkali metal and the carbon to be used are 1-10wt.% and 0.2-3wt.% based on the whole amount of the catalyst. Propylene treatment of the catalyst prior to the codimerization markedly improves the catalyst activity, thus increasing the space time yield of this compound and enabling reaction at lower temperatures, and also resulting in longer catalyst life.

Title: Ternary output circuit
Inventor: OKAMURA KENSHIRO
IPC: H03K19/20
Filed: 1985-05-17
Abstract: PURPOSE:To decide easily a potential being always stable without being affected by a load connected to an output terminal by providing the 3rd transistor (TR) and plural diodes and connecting them as specified. CONSTITUTION:When a TR 13 is turned on, an output potential point 7 goes nearly to a common potential. When the point 7 is nearly at the common potential, a current going to flow from a base of a TR 10 through the collector is blocked by a diode 8, then no problem is caused. When both the TRs 13, 11 are turned off, the point 7 goes to nearly a power supply potential. When the TR 13 is turned off and the TR 11 is turned on, since the base of the TR 10 is at a constant potential, the collector potential of the TR 10 is constant regardless of a load connected to the point 7. Then the potential at the point 7 is decided easily by the number of diodes connected between the base of the TR 10 and a high potential point 1.
