    Abstract: PROBLEM TO BE SOLVED: To suppress an increase of the number of wiring lines at a printing head loaded to a line printer.
    SOLUTION: Wiring lines from head chips 6 for discharging ink drops are made partly common by a wiring member (FPC) 19. At the same time, the wiring lines are made partly common by a latch circuit 60 and a control circuit 61 provided on a relay board 1b. The number of the wiring lines at a wiring member 50 connected to a control board is greatly reduced accordingly.

    Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device that has a high-performance resistor for heating where thermal expansion in the electrically heated resistor can be inhibited for improving a heat resistance property in the resistor, or heat radiation from the resistor to an electrode can be inhibited for efficiently generating heat, and to provide a printer. SOLUTION: In this semiconductor device, the resistor 20 is formed on an insulating film 13 on a semiconductor substrate, and an insulating film 15 is formed on the resistor 20. The resistor 20 is made of a conductive film and is used for heating. This printer has a head section with an opening 19 for discharging ink 16, the resistor 20 for heating the ink 16, and the driving circuit Tr. In this case, film stress in the insulating film 15 on the resistor 20 should show compressibility stress, and at the same time should be larger than that of the insulting film 13 under the resistor 20. Or, an insulating film with thermal conductivity that is sufficiently smaller than the insulating film on the resistor should be formed while the current application region of the resistor is being surrounded.

    Abstract: PROBLEM TO BE SOLVED: To improve sufficiently a reproducing output, that is, S/N (C/N) even when problems about restriction of recording density prescribed from conditions at the time of reproduction are dissolved and a recording information bit is made minute. SOLUTION: In a signal reproducing method of a magnetooptical recording medium in which a magnetic film of a magneto-optical recording medium is irradiated with a laser beam LB and recorded information is read out by magneto-optical interaction of a laser beam and a magnetic film in a recording magnetic section, a magneto-optical recording medium having at least a record holding magnetic film and a signal reproducing magnetic film is used, by irradiating this magnetic film with a laser beam, a magnetic section state is changed in the signal reproducing magnetic film, and recorded information is read out making it as power giving temperature in which a magnetic section state is not changed in the record holding magnetic film.

    Abstract: PROBLEM TO BE SOLVED: To provide a high performance recorder of high resolution in a high yield at low cost by raising dot density. SOLUTION: In the recorder, a slit-like branch passage 7 which is covered on its upper part with a cover 3 and partitioned with a branch passage wall 2 is provided on a head tip 1, and a plurality of dye flying parts 5 are respectively arranged on both sides of the other side of each branch passage 7. Then, dye passes through each branch passage 7 from a common dye feed passage, and fed simultaneously to a plurality of dye flying parts 5. Further, it can be fed also to the dye flying parts 5 from an interconnecting part 8 at an end part of the branch passage wall 2.

    Abstract: PURPOSE:To detect a minor loop in which a transfer error is generated and to effectively manage the address of data by adding the address information which can be discriminated from the data to the respectively same positions of the plural minor loops. CONSTITUTION:In a Bloch line memory 6, the address information which can be discriminated from the data is added to the respectively same positions of the plural minor loops 631-63m. Accordingly, since the same address information enters at the respectively same positions of all the minor loops 631-63m, for instance, when the address information of a minor loop is different from the address information of other residual minor loop, it can be considered to generate the transfer error. Thereby, the minor loop in which the transfer error is generated can be easily detected and the address information can represent the absolute address of the data corresponding in itself, so that the address of the data can be effectively managed.

    Abstract: PURPOSE:To surely read and write by selecting a gate part for reading and writing information to a stripe magnetic domain to the specified end part side of the stripe magnetic domain. CONSTITUTION:A chopping conductor 4 and a Bloch line shifting conductor 5 for generating a magnetic field HiPL in a local face for shifting the Bloch line, namely the gate part 2 is disposed at the end part side of the stripe magnetic domain of a side in which the orientation of a floating magnetic field in the end face of the arrangement face side of the Bloch line shifting conductor of the magnetic domain wall of the stripe magnetic domain is opposite to the orientation of the Bloch line to write the information to a minor loop and read the information from the minor loop. Thereby, the movement by the HiPL is surely generated in the vicinity of both the ends of the stripe and the Bloch line is effectively controlled according to the HiPL by this conductor 5.
