Title: Luminance signal chrominance signal separation
Inventor: HACHIMAN KAZUHIKO
IPC: H04N9/78
Filed: 1994-06-14
Abstract: PURPOSE:To reduce dot disturbance caused in the vertical direction with A small scale configuration by comparing image correlation energy sets based on a required sampling value so as to select a 1st or 2nd color signal filter. CONSTITUTION:A 1-line digital composite color image signal 20a and a delay digital composite signal 19a of one preceding line are inputted to an image correlation decision circuit 23, a horizontal luminance signal non-correlation energy extract circuit 32 extracts a signal DYH from a noted sampling point of one line and a sampling value of a reference sample point and a prescribed coefficient is multiplied with the signal DYH to calculate a horizontal direction non-correlation energy DH. Similarly a vertical non-correlation energy DV is calculated from a reference point sampling value in the signals 19a, 20b and color filters in horizontal and in horizontal/vertical direction are selected depending on the comparison result of both the energy sets DH, DV. Thus, the effect of leakage of a luminance and a chrominance signal onto mutual channels in an area where an image change is rapid in the vertical direction is reduced and dot disturbance is reduced.

Title: Internal reforming type fused carbonate type fuel cell system
Inventor: SASAKI MASAKAZU
IPC: H01M8/06
Filed: 1993-05-11
Abstract: PURPOSE:To simplify the scheme of a device, and thereby make the devise small in size. CONSTITUTION:The system is equipped with a heat exchange type pre-reformer 1, an anode gas manifold 3 and with an internal reforming type fusion carbonate type fuel cell 2, and thereby allows heat exchange to take place within the heat exchange type pre-reformer 1 between exhaust gas from the internal reforming type fusion carbonate type fuel cell 2 and fuel including hydrocarbon the carbon number of which is equal to or more than 2, and light naphtha, and concurrently allows steam reforming reaction to take place in the aforesaid fuel. Electricity is thereby generated by using reformed gas thus obtained through an anode gas manifold as fuel for the aforesaid internal reforming type fuel cell. By this constitution, hydrocarbon such as butane, light hydrocarbon and the like, the carbon number of which is large, can be used as fuel while possibility for carbon precipitation is being greatly reduced. The reformed gas of hydrocarbon becomes larger in volume by far than gas produced when methane is reformed, in this case, since anode gas can be supplied to the internal reforming type fusion carbonate type fuel cell with the volumetric flow rate of anode gas increased, so that anode gas can be uniformly distributed with ease to each single cell within the cell.
