Title: Contour emphasis circuit
Inventor: MOTODA KAZUMA
IPC: H04N5/208
Filed: 1993-11-12
Abstract: PURPOSE:To conduct contour emphasis giving natural impression by controlling an amplitude of a contour signal extracted from a video signal corresponding to a color area including the video signal. CONSTITUTION:Video signals a1, a2, a3 received from input terminals 100A, 100B, 100C are inputted to a specific color area discrimination circuit 120 and a contour signal generating circuit 130. The circuit 120 discriminates a degree of the input video signals included in a predetermined color area to provide an output of a contour signal (c). The circuit 130 extracts 1st contour signals b1, b2, b3 from the input video signals. A multiplier 140 controls the amplitude of the contour signals b1, b2, b3 depending on the contour control signal (c). Second contour signals d1, d2, d3 produced by the multiplier 140 are added to the video signals a1, a2, a3 by adders 150A, 150B, 150C to form video signals e1, e2, e3 subject to contour emphasis and they are outputted from output terminals 110A, 110B, 110C.

Title: Sheet conveyance device
Inventor: TOTSUGI TOSHIHIKO
IPC: B65H9/16
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To supply paper with high precision by constituting a lever held on a holder arranged in the upstream of a conveying roller in such a manner that traveling force in the direction of forward feed is energized to a tip of sheet to feed it reversely against a lever spring when the sheet is fed reversely due to the reverse rotation of the conveying roller. SOLUTION: When sheet P is inserted through a paper supply port 2a along a paper supply base 3 and a paper guide 3a and a sensor S1 detects a tip of the sheet, a motor is activated, a conveying roller 5 is rotated in the direction of forward feed of the sheet, and a tip of the sheet P is fed out by predetermined length from nips of the conveying roller 5 and a pinch roller 11. Next, the conveying roller 5 is rotated in the direction of reverse feed of the sheet to feed the sheet P reversely. At this time, since the sheet P is nipped by a lever 15 and a guide part of a holder 16, the holder 16 moves in the direction of reverse feed together with the sheet P. Consequently, the tip of the sheet P is searched, and then the conveying roller 5 is rotated in the direction of forward feed and is conveyed up to a printing and recording position of a recording head 14 with precision.

Abstract: PROBLEM TO BE SOLVED: To omit the machining of an inside diameter face of a boss part of a housing and the shrinkage fitting and press-fitting works by connecting an outer cylinder of a bearing with the boss part of the housing by using an insert. SOLUTION: A shaft part assembly body A is integrally constituted in a boss part 2a of a housing 2 by using an insert. Here, the shaft part assembly body A is set in split molds 18a, 18b which have cavities 12a, 12b which form the housing 2, and a constituent material of the housing 2 which is in a melted condition, for example, aluminum alloy, is poured into the split molds 18a, 18b for molding. Consequently, an outer cylinder of the shaft part assembly body A is firmly connected with the boss part 2a of the housing part 2. In particular, since a plurality (two) of grooves 17 are provided on an outer peripheral face of the outer cylinder 9, the outer cylinder 9 is firmly connected with the boss part 2a of the housing 2 in the axial direction (direction of pulling out).  As a result, it is possible to omit the mechanical machining for fitting bearing on an inside diameter face of the housing part.

Filed: 1991-10-30
Abstract: PURPOSE:To restrain the decrease of reliability of the insulating film of a lower electrode causing a problem in the manufacturing process of an integrated circuit containing a capacitive element whose lower electrode and upper electrode are formed of semiconductor layers. CONSTITUTION:After a semiconductor layer 3 for a lower electrode is deposited and etched to be a desired pattern, a nitride film 6 which is equal to or thicker than the lower electrode semiconductor layer 3 is formed by a CVD method. The nitride film 6 is etched by a dry etching method of intensive anisotropy, and left only on the lower electrode side wall. An insulating film whose thickness is calculated from a capacitance value is formed, and then an upper electrode is formed. Thereby an insulating film having gentle inclination can be formed on the lower electrode side wall, and a thick insulating film is formed, so that the reliability of a capacitive element can be improved. Since the insulating film is composed of a nitride film, the lover electrode side wall also can ensure a high capacitance value.

Abstract: PURPOSE:To prevent intermixing of a strong electrolyte resin and a weak electrolyte resin to prevent a lowering of quality of treated water, by separating a strong bed and a weak electrolyte-resin bed with a partition wall, providing a means for discharging liquids at a location a little lower than the upper surface of the strong-electrolyte layer disposed under the partition wall to conduct regeneration thereby. CONSTITUTION:A layer 3 of ion-exchange resins comprising weak electrolyte is formed in the upper section of an ion-exchange column 1, while a layer 2 of ion-exchange resins comprising strong electrolyte is formed in the lower section thereof. A liquid-permeable partition wall 4 which does not allow the resins to pass therethrough is interposed between said layers so as to separate them. Spaces for backwashing 5, 6 are provided above both of the layers of resins respectively, while a means for discharging liquids 7 is disposed at a location a little lower than the upper surface 2b of the layer 2 of resins. Ion exchange is conducted by flowing liquids downwardly from the upper portion of the layer 3 so as to be passed through both layers, while regeneration agents are flowed upwardly from the lower portion of the layer 2 so as to be discharged through the means 7, from which the agents are flowed downwardly from the upper portion of the layer 3 and discharged from the means 7 to be regenerated. As a result, intermixing of the strong and weak electrolyte resins are prevented, leading to the prevention of deterioration of treated water.

IPC: G03C1/79
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To produce a base body for a photographic paper having good smoothness without producing fog in the glass of an emulsion surface by foaming a resin laminated layer with a specified foaming rate and foam size. SOLUTION: The foaming rate of a resin laminated layer 3 formed on the back surface of a paper base is specified to 1.1-1.8 times. Since the foam size largely affects the effect to improve smoothness, the foam size is specified to 80-300μm. This base body for a photographic paper features that a foamed resin laminated layer 3 is formed on the opposite side (back surface) of a paper base body 2 to the side where a photographic image is to be formed (where an emulsion is to be applied) and that the surface roughness is increased to give good smooth property. By foaming the resin laminated layer 3, the amt. of the resin can be decreased. A resin layer or anchor coating layer may be formed so as to improve adhesion between the foamed resin laminated layer 3 and the paper base body 2.
