Title: Automatic equalizer
Inventor: SHIMAZAKI HIROAKI
IPC: H04B3/06
Filed: 1993-04-02
Abstract: PURPOSE:To simplify configuration and to perform exact equalization as well without requiring any large circuit scale calculation circuit or any high-accuracy D/A converter. CONSTITUTION:Corresponding to the output of a transversal filter 13, a decision output 21 and an error signal 22 are provided by a comparator 7. These signals are processed by a tap correction output calculation circuit 14 and respectively integrated by analog integration circuits 107, 108 and 108, and cumulative correction amounts are calculated corresponding to the initial value of a tap coefficient. The initial value is added to these amounts by adders 110, 111 and 112 and defined as the control signal of the transversal filter 13. Thus, since the amount of electric charges to be leaked from the analog integration circuits and the initial value is not affected by the leak as well, the tap coefficient can be exactly calculated, and automatic equalization due to zero forcing algorithm is enabled with extremely simple configuration.

Title: Communication control unit
Inventor: NISHI KIYOTAKA
IPC: H04L13/00
Filed: 1986-04-04
Abstract: PURPOSE:To secure the secrecy of the data transmitted to a terminal equipment by providing a state monitor part and transmitting the up-control signal to a central device only while both up-control and down-control signals are supplied. CONSTITUTION:In case the breaks 219 and 304 occur with a fast digital circuit, the ER control signals 217, 305 and 319 received from the time division multiplexing devices 203 and 315 are turned off. The MODEM 204 and 316 turn off the DR control signals 216, 306 and 3-6 and therefore the output of a monitor part 308 for devices 203 and 315 is turned off. Thus the time division multiplexing devices 202 and 313 turn off the DR control signals 213, 303 and 3-3 as well as the CI control signals 212, 302 and 3-2 against the central processing units 201 and 312. Then the terminal break state is informed. In such a way, the up-control signal is turned off by a state monitor part when the down-control signal is turned off. Thus it is avoided that a circuit is cut off due to the break of the down-control signal and therefore data are transmitted mistakenly to the terminal equipments other than a desired one.

Title: Magnetic recording medium
Inventor: MATSUFUJI AKIHIRO
IPC: G11B5/702
Filed: 1990-03-28
Abstract: PURPOSE:To improve dispersibility, surface smoothness, high packing property and high durability by using a binder containing a resin having a hydroxamic acid group as a functional group. CONSTITUTION:The magnetic recording medium consists of a nonmagnetic supporting body and a magnetic layer containing ferromagnetic powder dispersed in a binder. The binder contains a resin having a hydroxamic acid group as a functional group. Since this resin is easily adsorbed on the ferromagnetic powder to improve the dispersibility and packing property of the powder, a smooth magnetic layer can be obtained. Namely, this is because that metal atoms such as iron atoms of the ferromagnetic powder and the hydroxamic acid groups make a chelate structure and that the hydrogen bonding interaction with oxygen or OH groups on the surface of the ferromaagnetic powder is increased compared to other polar groups conventionally used. Thereby, dispersibility and packing property can be improved compared to a conventional medium, and the magnetic layer film is made strong, having improved surface smoothness and dulability.

Abstract: PURPOSE: To attain an image output in a proper direction without special notification of an upside and a down side of an original by applying rotation control to original image data based on the result of character recognition. CONSTITUTION: Upper/lower/left.right sides of image data stored in an image memory 602 are respectively supposed to be an upper side of an image and a recognition rate Pdi being a recognition result is obtained by a character recognition section 605. A maximum recognition rate among four PDi values is obtained as a maximum recognition rate P. When the recognition rate P does not exceeds a specified recognition rate, the processing is finished without any rotation processing. However, when the value P is larger than a lower limit of a valid recognition rate, the estimated paper direction Di is estimated to be a direction (i) in which the value P is obtained. Then input output attributes AI, AO of image data are inquired of an image data source 601 and an image data output destination 604.  A required correction rotating angle is calculated by a rule table stored in a nonvolatile memory in a CPU based on the direction Di and the attributes AI, AO. Then the correction rotating angle is used for a parameter of a rotation section 603 and then the processing is finished.
