Title: Fuzzy controller for positioning magnetic head
Inventor: HASHIMOTO ICHIRO
IPC: G11B5/56
Filed: 1989-07-12
Abstract: PURPOSE:To eliminate a read error by detecting the magnetic data position of a medium by a data position detecting means, outputting the most suitable manipulated variable based on a fuzzy rule for calculating the most suitable consequent part by a fuzzy inference control means with this data position as an antecedent part and executing fuzzy inference control to a head slight adjustment mechanism. CONSTITUTION:A fuzzy controller defines the data position of a magnetic card 15 detected through a magnetic head 13 as the antecedent part (condition part) and sets the fuzzy rule with the slight move quantity of the magnetic head 13 to be fine outputted corresponding to this data position as the consequent part (conclusion part). The most suitable manipulated variable is outputted as the consequent part based on the fuzzy rule from the data position, which is detected as the antecedent part, and the fuzzy inference control is executed to a pulse motor M by this manipulated variable so that the suitable data correspondent position can be obtained. Thus, the position of the magnetic head 13 is slightly corrected immediately to the suitable correspondent position and optimum magnetic data processing can be always obtained. Further, the magnetic data processing with high reliability can be executed without the read error.

Title: Ciphering adaptor
Inventor: YAMADA TOMOMI
IPC: G09C1/06
Filed: 1990-07-09
Abstract: PURPOSE:To omit the danger of decoding of the data even if this date is tapped by securing the correspondence between a key end the data based on a key having the value equal to the data on a single packet to be transferred. CONSTITUTION:A key is updated by an updating key set previously by a key updating system. At transmission, a data communication control system 10 adds the information the updating frequency and the identification of the key to a packet serving as a cipher header as the synchronization information. At reception, the system 10 retrieves the key set to the transmission side based on the information on the cipher header. Then the updating frequency set when the packet is ciphered is compared with the key updating frequency needed for decoding the packet at the transmission side based on the information on the cipher header. When no coincidence is obtained between both frequencies, the key synchronization processing is carried out by a key synchronization system 18. As a result different keys are used for each transmission or reception of the data for a single packet, the same key is never used twice.

Title: Moisture-proof paper
Inventor: KOBAYASHI HIDEHIRO
IPC: D21H19/10
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To obtain a moisture-proof paper capable of preventing a low molecular material in a moisture-proof agent layer 2 from migrating to a PPC(plane paper copier) paper surface-contacting therewith and thereby preventing the friction coefficient of the PPC paper from being decreased. SOLUTION: This moisture-proof paper is obtained by forming a moisture- proof agent layer 2 on a paper material 3 by coating a moisture-proof agent capable of being disaggregated by water. The moisture-proof agent contains a filler 4 compounded therewith. The filter 4 is not sedimented when coating because the filler 4 has 0.8-2.0 g/cm<3> bulk specific gravity, and a part of the filter 4 is protruded from the moisture-proof agent layer 2. When a PPC paper is wrapped with the moisture-proof paper 1, the protruded parts of the filler 4 are brought into contact with the PPC paper, and thereby a touch area of the basic material 5 of the moisture-proof agent layer 2 with the PPC paper is suppressed. As the result, the migration of a low molecular material from the moisture proof agent layer 2 to the PPC paper is prevented.

The single crystal 12-1 has little defects and is in a flat plane parallel to the substrate 11. The crystals grow to collide with each other to form intergranular boundaries 13 to cover the substrate 11. Thus, the electrode substrate is obtd. A recording layer of 0.5-30nm film thickness is formed on the substrate by Langmuir-Blodgett technique or the like. By this method, a smooth electrode substrate can be easily obtd.

Title: Ionic propulsion device vector control
Inventor: PIITAA SUMISU
IPC: B64G1/40
Filed: 1991-07-23
Abstract: PURPOSE: To obtain a control system for an ion thrust apparatus which generates a thrust force for a space ship. CONSTITUTION: In a discharge chamber 1, an ion thrust apparatus, for example, using an electrostatic field between a cathode 2 and an anode to accelerate propellant ions loaded with a positive charge, passing a screen grid 6' to reach or pass an accelerating grid 6, uses the relative movement between the two grids to change the direction of the ion beam departing from the accelerating grid. Thus, the reaction thrust force against the grid and the thrust apparatus is converted. This provides a simple means for thrust force vector control of the thrust apparatus.
