PROBLEM TO BE SOLVED: To prevent an increase of a chip area and a decrease of an operation speed by forming a high withstand voltage transistor for driving and a logic circuit for driving this transistor integrally on a substrate through application to, for example, an inkjet printer of a thermal system in relation to a liquid discharging head, a liquid discharging apparatus, a manufacturing method for a liquid discharging head, an integrated circuit and a manufacturing method for an integrated circuit. SOLUTION: The high withstand voltage transistor for driving is formed by an offset LOCOS structure. A sacrifice oxide film is formed and removed before a gate oxide film of the transistor is formed.

PROBLEM TO BE SOLVED: To provide a liquid jetting device which can reduce a driving current of a heating resistor element by stabilizing a resistance value of the element, and can make a power supply compact. SOLUTION: The liquid jetting device 1 has a liquid chamber 4 for storing a liquid to be jetted, the heating resistor element 7 set inside the liquid chamber 4 for generating bubbles in the liquid, and a liquid jetting nozzle 5 for jetting the liquid in the liquid chamber 4 along with the generation of bubbles of the liquid by the heating resistor element 7. The liquid is jetted from the liquid jetting nozzle 5 by impressing a driving electrical signal to the heating resistor element 7 and applying a heat energy to the liquid. The heating resistor element 7 is formed by forming a film of a compound of any one of Ta, Ti and W, and AlN. The resistance value of the heating resistor element 7 is thus stabilized, so that its driving current can be reduced, and the power supply can be made compact. COPYRIGHT: (C)2004,JPO

PROBLEM TO BE SOLVED: To control variations of the value of voltage to be applied to a head chip. SOLUTION: Wiring from a plurality of thermal resistors 8 mounted on a head chip 6 is connected to a relay board 1b. Variations of voltage generated in each head chip 6 are absorbed by arranging capacitors C on the board 1b. In addition, the relay board 1b is arranged right above a head chip module 1a.

PROBLEM TO BE SOLVED: To provide a recording method and recording device, capable of recording preferably by holding the recording liquid in the transfer part stably at the time of ejecting or vaporizing a recording liquid held in contact with a transfer part so as to be transferred on a member to be transferred disposed facing the transfer part, and transferring a predetermined image, or the like to the member to be transferred. SOLUTION: A fluorine resin film is provided on the upper surface of an ink weir 31 for forming a liquid repellent surface 24. Thereby, an ink 26 held in a transfer part 17 forms a meniscus 29 stably with respect to the boundary 30 of the liquid repellent surface 24 so as to be ejected in this state by micro bubbles generated by being heated by a heater 19, or the like for enabling a preferable printing operation.
Abstract:
PROBLEM TO BE SOLVED: To obtain a sufficient reproducing output even when recording informa tion bits are micronized. SOLUTION: In this method, an optical recording medium is irradiated with a laser light beam and the reading of the recorded information is conducted by the optical effect in the recording bits of the recording carrier layer of the optical recording medium and the laser light beam. In this case, at least the recording carrier layer laminated with a layer mainly contributing to recording holding and a layer mainly contributing to signal reproducing is irradiated with the laser light beam. Moreover, by raising the temperature of the recording carrier layer by the irradiation with the laser light beam, the information bit area of the temperature raised section is varied from the condition prior to the irradiation and the recorded information is read by the optical effect.
Abstract:
PURPOSE:To reproduce a recorded signal even when a distance between a magnetic recording medium and a magnetic yoke is somewhat varied by disposing the magnetic yoke between the magnetic recording medium and a magnetic probe. CONSTITUTION:The device is provided with a flexible supporting piece 5 formed in a prescribed length and supported at its one end side in the longitudinal direction and the magnetic probe 6 supported by the other end side of the supporting piece in the longitudinal direction to be opposite to the magnetic recording medium 2. Then, the device is also provided with a displacement measuring means 7 for detecting displacement of the supporting piece 5 in the direction of approaching and receding from the recording medium 2 and the magnetic yoke 8 consisting of a thin film magnetic substance, provided between the recording medium 2 and the probe 6. Since the magnetic yoke 8 is thus disposed between the recording medium 2 and the probe 6, even at the time of reproducing information recorded with high density by using technology of a scanning type probe microscope, fluctuation of magnetic force sensed by the probe 6 is diminished even when the distance between the recording medium 2 and the magnetic yoke 8 is somewhat varied. Consequently, the recorded signal can be reproduced without being influenced by varying the space between the recording medium 2 and the probe 6.
