摘要： A water base ink set for ink-jet recording includes a water base ink which contains an acid dye, and a water base ink which contains a basic dye. The water base ink contains a polymer which has an average molecular weight of 3,000 to 20,000 and which is represented by the following formula (1): wherein X represents H or COONa, and Y represents H, COONa, SO3Na, or CH2OR in the formula (1). R represents a substituted group having SO3Na with carbon atom or atoms of a number of 1 to 5. When the ink containing the acid dye and the ink containing the basic dye are mixed with each other, then the head discharge section is prevented from any clog-up, and it is possible to perform the stable jetting operation.

摘要： An ink cartridge for ink-jet recording apparatus includes an ink tank usable in an ink-jet recording apparatus and a water base ink filled in the ink tank. In the ink cartridge, the ink tank is formed of polyolefin containing a sorbitol derivative as a crystal-nucleating agent, and the pH of the water base ink filled in the tank has been adjusted to be not less than 4.0 to less than 8.0. This makes it is possible to prevent the sorbitol derivative, contained in the polyolefin as the crystal-nucleating agent, from depositing in the water base ink filled in the ink tank.

摘要： A method for selecting a resin or rubber material to construct an ink flow passage of an ink-jet recording apparatus includes immersing the resin or rubber material in water at 60° C. for 2 weeks in a tightly closed vessel, and determining an amount of eluted fatty acid derivative. If the amount of fatty acid derivative is not more than 20 ppm with respect to a total amount of the resin or rubber material, it is judged that the resin or rubber material is appropriate as the material for the ink flow passage. It is possible to select, by the convenient method, the material which is most suitable for the actual condition of use, without examining components and compositions of respective materials.

摘要： Embodiments in accordance with the present invention reduce the structural stress applied to a head, and to achieve the effective control, when the clearance between the head and a disk is adjusted by using a heater. According to one embodiment, the hard disk controller/microprocessing unit (HDC/MPU) controls a slew rate of a heater at the time of TFC (Thermal Fly height Control). In response to processing conditions, a HDC/MPU changes a slew rate of the output of electric current/voltage applied to the heater. This makes it possible to reduce the head stress, and to achieve the effective TFC. To be more specific, with reference to a temperature/slew rate table, the HDC/MPU changes a slew rate in response to the temperature in the read/write processing.

摘要： An ink-jet recording apparatus includes a rubber member in an ink flow passage. The rubber member is made of a rubber composition including a rubber base polymer selected from ethylene-propylene diene rubber polymer and isobutylene-isoprene rubber polymer, and at least one trapping agent selected from calcium carbonate, silicon dioxide, talc, and clay. The trapping agent is effective for absorb-trapping various types of additives that may be present in the rubber member. The additives in the rubber are thereby held in the rubber structure and prevented from being eluted into the water-based ink or the preservative solution, which can lead to clogging of ink nozzles and the like.

摘要： Embodiments of the present invention help to improve the cost, mountability, and reliability of a magnetic disk drive that regulates a fly height of a magnetic head slider correspondingly to the operating altitude of the drive by using an air pressure sensor and a heater. According to one embodiment, a preamplifier is a semiconductor chip formed by three-dimensionally laminating thin film circuits on a bulk silicon wafer. An air pressure sensor is integrally formed on the semiconductor chip through a semiconductor process. The air pressure sensor is configured to include an isolating cavity, a diaphragm that deflecting in response to a change in a pressure difference between the isolating cavity and the outside, and lower and upper electrodes and for detecting variation in electrostatic capacitance. The preamplifier including the air pressure sensor integrally formed therein is attached to a flexible printed cable (FPC) to oppose the FPC. A through-hole is provided in a portion opposite the air pressure sensor of the FPC to introduce air pressure in an operating environment into a diaphragm of the air pressure sensor.
