Title: Service system of still picture information
Inventor: MIHARA MASATAKA
IPC: H04N7/173
Filed: 1984-04-19
Abstract: PURPOSE:To perform the effective retrieval and transmission control of picture information by controlling the repetitive reading frequency of information on each screen in order to control the output time of a still picture. CONSTITUTION:When a program No. is supplied through a keyboard 108 of a terminal booth 109, a CPU100 refers to a program table of a microdisk 102. Then the ''output time'' of each screen forming programs is extracted together with the ''store areas'' on still picture files 103 and 104. The retrieval commands are delivered to both files 103 and 104. At the same time, the ''switch data'' and a ''write command'' are sent via a controller 110 to a video switcher 105 and a frame memory 106 respectively. The ''program table'' stores repetitively the ''store addresses'' corresponding to the output time of still pictures. This ensures the retrieval and transmission control of picture information without increasing the load of the CPU100.

Title: Chroma signal processor
Inventor: MORO EIJI
IPC: H04N9/83
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To eliminate an analog ACC amplifier and an analog ACC detection part and to reduce the cost of a chroma signal processor by preparing an ACC gain control part, consisting of an ACC amplifier and an ACC detection part at only a digital signal processing part. SOLUTION: A digital ACC circuit part, consisting of an ACC amplifier 40 and an ACC detection part 41, is prepared at a digital signal processing part 47. The amplifier 40 is placed at the preceding stage of a decoder 5 and controlled by the output received from the part 41. Since the configuration is such that the ACC detection input signal of the part 41 is given from a position set after a switch 7, the disturbance of adjacent crosstalks can accordingly be avoided. The position where the amplifier 40 is inserted is set at a position right after an A/D converter 4, i.e., at the preceding stage of the decoder 5. Thereby, the amplitudes of signals which are processed by the circuits of the subsequent stages including the decoder 5, a comb filter 6, etc., are all stabilized, and the problems including the overflow, etc., will hardly occur.

Title: Replacing method of w/o emulsion hydraulic fluid
Inventor: KAWASHIMA KOJI
IPC: F15B21/06
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To timely replace an operating fluid by measuring the concentration of an inorganic dispersant contained in the hydraulic fluid at circulating supplying time, and replacing the whole hydraulic fluid quantity with a new hydraulic fluid when a measured value becomes a preset desired value or less. SOLUTION: A material by adding a barium-based inorganic dispersant is applied as a hydraulic fluid, and the moisture concentration hardly reduces up to one-six months from the time when starting use, largely reduces over eight months from seven months thereafter, falls outside the control range, and it is estimated that this large reduction is caused by water particles which have started to coagulate in oil. While, the dispersant starts to gradually reduce on and after four months, and suddenly reduces over eight months from seven months. This means that the dispersant reliably starts to coagulate from about four months, and is through that the water particle is coagulated because large reduction over eight months from seven months coincides with a case of the moisture concentration. Therefore, performance of the hydraulic fluid can be controlled by paying attention to a change in the concentration of the dispersant.

Title: Vapor brazing method for al or al alloy
Inventor: YAMAGUCHI MOTOYOSHI
IPC: B23K3/00
Filed: 1989-03-30
Abstract: PURPOSE:To improve the quality, such as excellent corrosion resistance, by subjecting brazing members to a brazing in a nonoxidative atmosphere where the vapor generated from the melt of KF and AlF3 exists. CONSTITUTION:The vapor emitted from the melt of the KF and AlF3 refers to the vapor of the potassium fluoroaluminate complex essentially composed of KAlF3 and an assembly is placed in the nonoxidative atmosphere where this vapor exists, by which the extremely slight amt. of the vapor is uniformly stuck to the assembly and the oxide Al films on the surface are broken to accelerate wetting and to form uniform fillets at joining points. The nonoxidative atmosphere may be any of nitrogen, Ar, CO2, etc. The potassium fluoroaluminate complex is recommended to be used by previously applying the same to the internal joint parts with which the brazing is difficult and by drying the coating in the case of an evaporator of a drawn cup type having the joint parts where the vapor hardly exists for the structure of the assembly. The production process is shortened in this way and the surface of the members after the brazing is clean. The corrosion resistance is improved as well.

Title: Binary-coding device
Inventor: HONGO YASUO
IPC: G06K9/38
Filed: 1986-04-09
Abstract: PURPOSE:To obtain an optimum threshold by detecting the minimum (maximum) value in a moving window by a minimum (maximum) value detecting means and determining a background density value on an aiming position based on a difference between the detected value and the preceding background density value. CONSTITUTION:A binary-coded threshold generating circuit 6 extracts the change of a minimum (maximum) value based on the movement of the window, determines whether the influence of a shadow, halation or the line width of a character exists or not based on the size of the change and estimates the background density value at an aiming picture element to determine the binary- coded threshold TH. Since the background value is stored and estimated with a short interval in accordance with the movement of the window, the binary- coded threshold TH can be determined without directly exerting the influence of shadows or halation upon the window position even if the minimum (maximum) value is locally different from the background density value.

Title: Method and device for scanning sheet object
Inventor: TSUDO SATOSHI
IPC: H04N1/04
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To simplify a configuration and to attain cost reduction by unnecessitating a cancel mechanism for detaching a carrier part from a sheet object by providing a scanning part with a storage zone for temporarily storing an entire sheet away from the carrier part, and carrying the sheet object for sub-scanning in the state of completely detaching it from the carrier part. SOLUTION: A read part 36 is provided with a storage zone 42 for temporarily storing an entire cumulative fluorescent sheet 20 made to be away from a carrier part 32. Therefore, the cumulative fluorescent sheet 20 is stored temporarily from the carrier part 32 into the storage zone 42 and carried later in the direction of the arrow A for sub-scanning, while being held between only first and second rollers 50 and 52 constituting a sub-scanning conveying means 44. Accordingly, it is economical by dispensing with a comparatively expensive nip cancel mechanism for canceling the nip of a roller pair 38 constituting the carrier part 32. Furthermore, it is sufficient only to provide the storage zone 42 equipped with a guide plate 58 and a movable guide plate 60 for switching a path with a solenoid 62 and a structure can be simplified easily.
