PROBLEM TO BE SOLVED: To prevent generation of steps by a coating type insulating films and also to prevent deterioration of a heating element by applying, for example, an inkjet printer by a thermal system which has both the heating element and a transistor for driving the heating element formed integrally on a substrate, to a liquid discharging head, a liquid discharging apparatus and a manufacturing method for a liquid discharging head. SOLUTION: An interlayer insulating film is formed by the coating type insulating films 55 and 68. Silicon insulating films 56, 59, 69 and 73 are formed on a surface layer of the interlayer insulating film and on the inside wall faces of through holes 58 and 72 set in the interlayer insulating film.

PROBLEM TO BE SOLVED: To provide a liquid ejection head and a liquid ejector being applied to a printer for ejecting an ink liquid drop by driving a heating element, for example, in which crosstalk can be reduced even if intrusion of dust into a liquid chamber is prevented by forming protrusions along a channel. SOLUTION: Intrusion of dust into a liquid chamber 22 is prevented by forming protrusions 29 in such a shape as a pressure wave generated by driving an energy generating element 27 is reflected to a generating source.

PROBLEM TO BE SOLVED: To provide a cleaning method, a cleaning liquid and a cleaning cartridge applicable to a thermal ink jet printer, for example, in order to remove deposits adhering to the thermal action surface of a liquid chamber. SOLUTION: In the cleaning method of a liquid ejection head where liquid held in a liquid chamber is heated by driving a heating element and ejected from a nozzle, a specified cleaning liquid is introduced to the liquid chamber 18 in place of the liquid, and the heating element is driven to remove deposits adhering to the thermal action surface of the liquid chamber 18 by the cleaning liquid which is a solution for oxidizing/dissolving a metal layer 15.

PROBLEM TO BE SOLVED: To improve sufficient reproduction output and a signal-to-noise (carrier-to- noise) ratio even when the recording information bit of a signal recording and reproducing device for a magneto-optical recording medium is microminiaturized. SOLUTION: The magneto-optical recording medium which has a first magnetic film 11, a third magnetic film 13 held with recording magnetic domains and a second magnetic film 12 arranged between these magnetic films and of which the second magnetic film 12 consists of the magnetic film having a Curie temp lower than the Curie temperatures of the first magnetic film 11 and the third magnetic film 13 is used. Further, the device has a means for applying an external magnetic field where the sum of a demagnetizing field and the external magnetic field attains a value smaller than the coercive force Hc3 of the third magnetic film. The magnetic domain state of the first magnetic film is changed by applying a reproduction temperature TpB which is higher than the Curie temperature of the second magnetic film and at which the magnetization state of the third magnetic film may be held in the position of the magneto-optical recording medium of the portion irradiated with a laser beam and the reading-out of recording information is executed by detection of the Kerr rotating angle or Faraday rotating angle of the laser beam.
Abstract:
PROBLEM TO BE SOLVED: To eliminate printing defects by making the positive supply of an ink to the transfer part of a printer head of a dye vaporization thermal transfer type which vaporizes and transfers the ink. SOLUTION: An auxiliary wall 47c is formed in an adjacent supply passage S to a transfer part T, and the liquid level of an ink 8 is raised between the auxiliary wall 47c and partition wall 47a to prevent the ink 8 from running out in the supply passage S. Thus the ink 8 consumed in the transfer part T is replenished spontaneously by capillarity and thus the trouble-free continuous supply of the ink 8 to the transfer part T is ensured.

PROBLEM TO BE SOLVED: To elevate the transfer efficiency of a recording material and to improve transfer density with high resolution by constituting so that a recording head has a recording material flight part and contacts a recording material relatively slantingly, and the recording material flight part and the recording material are held at a prescribed distance by the contact. SOLUTION: In a printer head 25, a printed board 12 and a head chip 1 are arranged in parallel on a base 10 and brought into contact, and on it is installed a cover 18. A recording head is arranged downward, and one end 10a of the base is contacted with a recording material 20 so that the recording head 25 makes an inclined angle of θ with the recording material 20. The installation part of the printed board 12 of a base 10 is formed thinner by the thickness of the printed board 12. A cover 18 is a cross section in which an inclined surface is formed on a surface opposite to the recording material 20, and its side forms a wall surface to make a box shape as a whole.
