Title: Scene change detector for digital video.
Inventor: CHEN XUEMIN
IPC: H04N7/32
Filed: 1997-09-26
Abstract: In a method for detecting a scene change between a prior video picture and a current video picture of a sequence of pictures, an average luminance value is determined for a block pair of the prior and current video pictures. Preferably, the blocks of the block pair are located, respectively, in the same relative position n the sensation value is determined using a differencebetween the average luminance values. If the incremental visual sensation value excedds a block indicated. In particular, if the minimum of the average luminance values of the current and prior picture blocks exceeds a dark scene thereshold. The incremental visual sensation value is determined using the ratio of (a) the absolute value of the difference between the average luminance values of the current and prior picture blocks. Otherwise the incremental visual sensation value is determined using the ratio of(a) the absolute value of the difference between the average luminance values, and (b) the minimum of the average luminance values of the current and prior picture blocks. Otherwise, the incremental visual sensation value is determined difference, and (b) the dark scene thereshold. The based on the relative amount of motion and the current picture type.

Abstract: Provided is a method of manufacturing a semiconductor device according to the present invention which includes in a following order: a MOS structure forming step where a gate electrode is formed on a first main surface side of a semiconductor base substrate with a gate insulation film interposed therebetween and, thereafter, an interlayer insulation film is formed so as to cover the gate electrode; a metal layer forming step where a metal layer in a state of being connected with the gate electrode is formed over the interlayer insulation film; an electron beam irradiating step where a lattice defect is formed in the inside of the semiconductor base substrate by irradiating an electron beam to the semiconductor base substrate in a state where the metal layer is set to a ground potential; a metal layer dividing step where the metal layer is divided into a plurality of electrodes; and an annealing step where the lattice defect in the semiconductor base substrate is repaired by heating the semiconductor base substrate. With such a MOSFET, it is possible to manufacture a semiconductor device which can reduce a parasitic built-in diode recovery loss compared to a case where an electron beam irradiating step is not performed, and has a V TH characteristic substantially equal to a V TH characteristic in a case where an electron beam irradiating step is not performed.

Title: Method for purifying fatty acid methyl esters
Inventor: PENG REN
IPC: C11B3/04
Filed: 2022-10-11
Abstract: The present disclosure provides a method for purifying fatty acid methyl esters, which comprises mixing crude fatty acid methyl ester with nitric acid to react organic sulfur in the crude fatty acid methyl ester with nitric acid, and then washing the reaction system with an aqueous glycerin solution, and then separating oil and water in the system washed with the aqueous glycerin solution to give a desulfurized fatty acid methyl esters. In the present disclosure, organic sulfur such as glucosinolate is decomposed into water—soluble sub— stances such as carboxylic acid, glucose, thione and hydrogen sulfate ions by using nitric acid, and then the adsorption of sulfides in the elution water is increased by glycerol, thereby removing these water—soluble substances, to prepare desulfurized fatty acid methyl esters, not only the prepara— tion process has low energy consumption, the preparation method is simple, and there is basically no loss of fatty acid methyl esters; the water phase produced after washing in the 20 present application can also be used as fermentation water for bio—organic fertilizer, the whole preparation process is pol— lution—free and does not generate exhaust gas, waste water and solid waste, which is green and environmentally friendly, and is especially suitable for industrial production.
Patent NL-6517211-A (NL)
IPC: B65G43/06
Filed: 1965-12-31
Abstract: 1,060,896. Conveyers. H. TIEFENBACH. Jan. 4, 1966 [Jan. 19, 1965], No. 230/66. Heading B8A. [Also in Divisions G1 and H3] Contacts r1 are opened by a relay 10 to operate an alarm (not shown), or stop the drive of a conveyer (not shown), when the return pulley or roller of the conveyer belt either stops rotating or rotates in the wrong direction. A permanent magnet (not shown) carried by the return pulley, operates a change-over switch 18 periodically to produce negative pulses alternately on the bases of transistors 8 9. Delay capacitors 6, 7, controlled respectively by variable resistors 16, 17 ensure that the transistors remain conductive to maintain current through the relay 10 provided the switch 18 changes at predetermined rate. Thus if the return wheel ceases rotation, one or other transistor ceases to conduct, and contacts r1 are opened. The base of a further transistor 20 is connected to a switch 24 which is operated by the return pulley magnet after the switch 18 has been operated. A relay 19 in the circuit of the transistor 20 controls contacts r2 in the base circuit of transistor 8. Thus if the return pulley rotates in the wrong direction, switch 24 opens before switch 18 changes to pulse the transistor 8. The latter, however, is prevented because relay 19 has previously opened contacts r2. In these circumstances contacts r1 are therefore caused to open and operate an alarm &c.

Title: Treatment vessel with granular bed for fluids - has pressure balancing pipe extending from below to above bed
IPC: B01D24/14
Filed: 1978-09-12
Abstract: A pressure unloading line extends from the zone below the partition supporting the granular bed, to a height above the highest level reached by the bed during its working, in a filtration or ion exchanging plant. The pipe forming the line is dimensioned to cope with the main flow of the fluid to be treated. Similarly to conventional plant, it comprises a cylindrical pressure vessel with feed and drain connection and a system of tubes with openings in their wall positioned a little way above the partition and connected to >=1 fluid line. All the feed and drain connections for the main flow of the fluid pass through the bottom of the pressure vessel. Each pressure compensating pipe is provided at its upper end with a flow distributor. Used as a filter or as an ion exchanger. The bottom partition supporting the granular bed is not a sieve so that additional supports are not necessary. The pipe balancing the pressure above and below the bed prevents the space below the partition affecting the concn of the fluid during regeneration.
