Title: Area dividing system for document image
Inventor: SATO NOBUYUKI
IPC: G06T1/00
Filed: 1990-10-18
Abstract: PURPOSE:To limit the object for executing a detection processing of a boundary candidate to only a boundary area, to shorten the time required for the detection processing of the boundary candidate, and also, to divide a document image into areas at a high speed by extracting the boundary area, based on an image feature of each block. CONSTITUTION:A rectangle dividing part 221 divides image data of a document image store part 211 into plural rectangular blocks and inputs them successively to an image feature quantity calculating part 222, derives average density, respectively and stores it in a feature quantity store part 212. A difference calculating part 235 derives a difference   of the image feature quantities of each adjacent block, compares it with a threshold of a threshold store part 213, and based on its result, a boundary area extracting part 224 detects combination which exceeds the threshold and extracts a boundary area. A boundary candidate detecting part 2225 generates a mask of an initial value stored in a mask size store part 214 and detects a white picture element part as a boundary candidate, and an outline tracking part 226 selects continuous boundary candidates. An area extracting part 227 extracts the part surrounded by the boundary candidate, and divides it as one area. In such a way, the detection time is shortened, and a document image can be divided at a high speed.

IPC: G11B11/10
Filed: 1985-12-11
Abstract: PURPOSE:To satisfy vertical magnetic anisotropy and coercivity, which are required as a vertical magnetic recording medium that comprises calcium oxide, cobalt oxide and iron oxide, by limiting each component at specified composition ratios. CONSTITUTION:A material comprises calcium oxide, cobalt oxide and iron oxide. The material is expressed by a general formula: CaO-yCoO-zFeO3/2 (where x, y and z represent mol percentages of their components, and x+y+z=100). Then the composition ratios lie in a range surrounded by a polygon A1A3E3E1, in which x, y and z correspond to apexe points A1, A3 E3 and E1 in the Table that are the apexes of the polygon (except for the composition ratios on the lines connecting the points A1, A3, E3 and E1). Thus the magnetic recording material, which is chemically stable and satisfied the characteristic required for vertical magnetic recording and optical magnetic recording, is obtained.

Title: Nonvolatile semiconductor storage device
Inventor: NAKAJIMA HIDEHARU
IPC: H01L27/115
Filed: 1991-10-01
Abstract: PURPOSE:To enable finning and low voltage by improving injection efficiency of hot carrier to a floating gate and by improving write characteristics. CONSTITUTION:A floating gate of EPROM of a lamination gate structure is constituted of a polycrystalline Si film 24 and a polycrystalline Si film 26 whose sidewall is higher than a thickness of the polycrystalline Si film 24. Thereby, even if a plane area of a storage cell is the same, an opposition area of a floating gate and a control gate is wider than that in a structure wherein a floating gate is formed of the polycrystalline Si film 24 alone. Therefore, electric potential of a floating gate can be made close to electric potential of a control gate by enlarging a combination capacity between a floating gate and a control gate enough larger than a capacity between a floating gate and a channel.

Title: Electronic volume circuit
Inventor: KAKIHARA HISANOBU
IPC: H01C13/00
Filed: 1988-11-07
Abstract: PURPOSE:To make smaller a noise when a volume is made minimum by detecting that the volume of a variable voltage source for adjusting the volume becomes minimum. CONSTITUTION:When a detecting circuit 5 detects that the volume becomes minimum, it gives a detecting signal to a change-over switch SWM for muting. The switch SWM is switched to a differential step M side for muting by the detecting signal. Then, a differential step composed of transistors Tr Q9 and Q10 is made inactive. A reference voltage Vref is given to the base of a Tr Q14. The current in accordance with the difference in the voltage given to the base of Tr Q14 and Q15 is given to the base of a Tr Q13 and the conductivity of the Tr Q13 is changed. For that reason, the base potential of a Tr Q15 is also changed, finally, the base potential of the Tr Q14 and Q15 is approximately made equal and then, the balance is kept. As the result, the voltage (voltage Vref) unrelated to a variable voltage source V1 for adjusting a volume is outputted to an output terminal 2.

Title: Tape recorder
Inventor: IMAOKA TOSHIO
IPC: G11B27/02
Filed: 1986-11-25
Abstract: PURPOSE:To simply execute punch-in by interlocking on/off of a recording bias with the on/off control of an erasure current so as to eliminate the need for bias control. CONSTITUTION:A recording signal of a prescribed level is fed from an input circuit 13 to a muting circuit 14, an erasure head 7 is opposed to a track position B and when a recording/reproducing head 8 is opposed to a track position, a punch-in control signal is sent from a control circuit 26. Thus, an erasure/ recording bias control switch SW11 is turned on and a muting control switch SW25 is turned off. The head 7 erases the right side from the position B and a recording bias current flows to the head 8 and the signal level is lowered at sections A-B where no head 7 does not apply erasure scanning. Then the head 8 is opposed to the position B in response to the output of a delay circuit 27 and a new signal is recorded from the right side. As a result, the track signal level is the addition between the original signal and the new signal and the level reduction of the sections A-B is compensated.

Title: Method for forming image on envelope
Inventor: MIYAMOTO TOSHIO
IPC: G03G15/22
Filed: 1993-11-10
Abstract: PURPOSE:To prevent an envelope from wrinkling by providing an envelope main body with a fixing member preventing a pair of constituting pieces from being relatively moved in a surface direction. CONSTITUTION:An adhesive tape provided with a prescribed adhesive surface is used as a deviation preventing tape 1 being the fixing member which can be peeled. The tape 1 is stuck to the lower side (inside) of a flap P3 so as to fix an inside between a back surface P2 and a front surface P1 being as a pair of constituting pieces. When the envelope main body A is carried by the fixing device of a copying machine, it is interposed and carried by the rotation of a fixed roller (driving of metal whose rigidity is high and a pressure roller (driven) such as a rubber-like elastic body whose rigidity is low. When the main body A is interposed and carried by rotating a pair of rollers in such a way, it is closely brought into contact with the roller whose rigidity is high and it arcs because the roller whose rigidity is low is elastically deformed. Since the surfaces P1 and P2 of the main body A are fixed, the actual carrying quantity of the front and the back surfaces is made to coincide.
