Title: Judgement device for attribute of picture
Inventor: HAMAGUCHI YOSHITAKA
IPC: G06T7/00
Filed: 1993-07-14
Abstract: PURPOSE:To improve the precision of judgement and to facilitate the setting and adjustment of a threshold. CONSTITUTION:A picture 1 inputted through an area division part 2 is divided into plural and small areas in specified and equal sizes by a Hausdorff dimension calculation part 3, and the number of the small areas including black picture elements is obtained among the small areas, for example. Then, the number of the small areas including the black picture elements is similarly obtained by changing the size of the small areas. Then, a one-dimension, a two-dimension or a Hausdorff dimension becoming the other real number are calculated from the result, and they are extracted as the feature quantity of the picture 1. When the feature quantity is a value approximated to '1.0', for example, an attribute judgement part 4 judges that the attribute of the picture 1 is a graphic, and judges the attribute of the picture is a photograph when the quantity is approximated to '2.0'. At the time of judgement, the threshold can be adjusted based on the value of the dimension which is intuitively and sufficiently recognized.

IPC: H01L29/66
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To provide an electron source structure having a uniform emission density of emitted electrons by composing the structure by forming a conductive negative electrode on one side of an insulating board with its one side in contact with the board, covering the negative electrode with an insulating film, and covering the insulating film with a positive electrode constituted of an LB film. SOLUTION: A conductive negative electrode 11 is formed on one side of a board 1 with its one side in contact with the board. An insulating film 12 is so formed as to cover the negative electrode 11. The insulating film 12 is covered with a positive electrode 13 which is made of an LB film. When a certain voltage is applied between the negative electrode 11 and the positive electrode 13, electrons are emitted tunneling through the insulating film 12. For the positive electrode 13, an LB film of amphipathic pyrrole that is made by means of electrolytic oxidation polymerization so as to retain conductivity is preferable. This allows the positive electrode 13 to have a small, uniform thickness, high electron emission efficiency and highly uniformly density of emitted electron. For the insulating film, an insulating LB film or alumina is preferable.  For the negative electrode, an aluminum material is preferable.

Title: Read only semiconductor storage device
Inventor: KUKI MASARU
IPC: H01L27/10
Filed: 1989-07-28
Abstract: PURPOSE:To manufacture the device at low cost by using a mask ROM as a basic memory and reading a data in an EPROM only when a data error exists. CONSTITUTION:When a data of a mask ROM array 1 has an error, a correct data is written and stored in an EPROM array 5 in advance and an erroneous data in the array 1 is stored in an address storage circuit 6. In the case of readout, when the inputted address and the address stored in the circuit 6 are identical, an address coincidence detection circuit 7 detects the coincidence of both the addresses and outputs a signal to read out the correct data stored in the array 5. On the other hand, when both addresses differ, the circuit 7 detects the dissidence of both addresses and outputs a signal to read the stored data of the array 1. Thus, a correct data in the array 1 is read. Through the constitution above, since the array 1 is used as the basic memory, the memory is manufactured inexpensively.
