Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To ensure the stability of a detection operation of letter box detection and to enhance the detection performance. SOLUTION: A black level detection circuit 14 in a letter box detection circuit 19 compares a video signal from a video demodulation circuit 12 with a threshold level from a threshold level generating circuit 15 to detect whether or not an object line is at a black level and to confirm the continuity of a black level in a field thereby discriminating a main image start/end line. A time arithmetic circuit 16 provides a discrimination output of 'normal' when the invalid main image start/end line is consecutive for a prescribed time and of 'letter box' when the valid main image start/end line is consecutive for a prescribed time. On the other hand, a scene change detection circuit 17 detects a scene change from a video signal demodulated by the video demodulation circuit 12.  A time arithmetic control circuit 18 varies a threshold level for the discrimination of consecutive time by the time arithmetic circuit 16 depending on the presence of the scene change.

Title: Phosphoric acid type fuel cell and its operation method
Inventor: YAMAZAKI OSAMU
IPC: H01M8/04
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a high output stably from the beginning by using a phosphoric acid solution containing a molybdic acid or molybdenum oxide in advance as an electrolyte. SOLUTION: An output characteristic is improved by means of the increase of a cell voltage and a concentration is set so as to prevent an internal short circuit by ionizing a molybdic acid or molybdenum oxide contained at 0.3-15 mmol/dm3 in a phosphoric acid of 100% concentration to activate an oxidation-reduction reaction. A long-term stable output is provided by keeping the concentration of molybdenum generally constant. It is recommended that an oxygen containing gas that is given a low oxygen partial pressure as compared with a normal operation by adding hydrogen or an inert gas to the air before the normal operation is fed to an oxygen electrode so as to operate a fuel cell at a lower potential than that at the normal operation, and the molybdenum adhering to the electrolyte layer side of the oxygen electrode by being reduced further increases the cell voltage.  It is effective that a preliminary process to generate an electrochemical reaction accompanied by oxygen generation and oxygen reduction is executed to an oxidation electrode, and thereby, the cleaning of the surface of platinum and the increase of the adhesion strength of the molybdenum are realized.

IPC: H04N1/41
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To realize a spot color copying machine in which a specific color image is copied with the same memory capacity as that of a monochromatic copying machine. SOLUTION: A data separate section 2 uses a specific color flag signal to separate multi-gradation black and white/specific color mixture image data into black and white data and specific color data and they are fed to a black and white data coding section 5 and a specific color data coding section 6. They are coded separately, and code data La, Ld, ϕij are fed to a code data conversion section 7. Simultaneously a color mixture discrimination section 4 discriminates whether or not a color is mixed in the data.  When the color is not mixed in the data based on the result of discrimination of the color mixture discrimination section 4, the code data conversion section 7 selects the code data fed from the black and white data coding section 5 or the specific color data coding section 6 and replaces the least significant bit of the code data Ld with a result of OR processing by the color mixture discrimination section 4. When any color is mixed, the high-order 4-bits of the code data La fed from the black and white data coding section 5 and the high-order 4-bits of the code data La fed from the specific color data coding section 6 are linked and the linked data are stored in a code memory 8 as new code data La.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of cavitation phenomenon and the denaturalizing of a heat medium within a circulation pump by controlling the opening or closing of a valve means so that the pressure in a tank rises higher by a specified value as compared with an saturation pressure with respect to a temperature value detected. SOLUTION: The opening or closing of automatic valves 40 and 43 is controlled by a controller 5 so that the pressure in a tank 21 rises higher by a specified value as compared with a saturation pressure with respect to the temperature of a fluid within the tank 21 as detected by a temperature sensor 45. The pressure in the tank 21 is fed back by a pressure sensor 18 to a controller 5. Hence, the pressure in the tank 21 is maintained by a specified value as compared with a saturation pressure with respect to the temperature of a fluid in the tank 21 sucked by a circulation pump 22 so that a necessary forcing pressure is applied into the circulation pump 22 ceaselessly to eliminate cavitation phenomenon within the circulation pump 22.  Thus, the tank 21 is always filled with an inert gas such as nitrogen gas to be kept from contacting from air thereby preventing denaturalizing of the heat medium 27 by oxidization thereof.
