摘要:
A plating method on a glass base plate is disclosed. The method allows an electroless plating film to be formed on a base plate composed of a glass material with excellent adhesivity through a process that removes alkaline and alkaline earth metals on the surface of the base plate. Also disclosed is a method of manufacturing a magnetic recording medium employing the method of plating on a glass base plate. Before forming a plating film in a step of electroless plating, a series of surface treatments are conducted on the surface of the base plate composed of a glass material. The series of surface treatments comprises at least an ultraviolet light irradiation, an etching treatment, an adhesion layer formation treatment, a catalyst layer formation treatment, and a catalyst activation treatment.

An information processing device to which data can be input by the use of a rotary bezel. A pulse-count detection sensor unit 32 and a rotational-direction detection sensor unit 33 read an optical pattern which is formed on the rotary bezel to generate a series of pulse signals. The pulse-count detection sensor unit 32 and the rotational-direction detection sensor unit 33 are arranged such that a phase difference occurs between the signals of the sensor unit 32 and the signals of the sensor unit 33, so that it is possible to detect the rotational direction of the rotary bezel. A data-signal generating element 81 generates a data signal on the basis of the detected rotational angle and the pulse count generated by the pulse-count detection sensor unit 32.

摘要:
A method and apparatus for replenishing depleted portions of an ink layer of an ink sheet formed with a conductive ink layer disposed on an insulating layer from which ink has been transferred, without unintentionally supplying ink to undepleted portions of the ink layer are provided. Electrically conductive replacement ink is charged and supplied onto an intermediate transfer roller having a dielectric layer disposed on an electrically conductive layer. Charge is supplied to the insulating layer side of the ink sheet and replacement ink on the intermediate roller contacting the ink sheet at depleted regions of the ink sheet is transferred from the intermediate roller to the depleted portions by electrostatic attraction and not to undepleted portions. The method and apparatus are adaptable for multi-color ink sheets and can be employed in connection with a printer or image forming device.

An object of the present invention is to provide a plating method on a glass base plate. The method allows forming a plating film on a base plate composed of a glass material with excellent adhesivity and homogeneity by means of an electroless plating method even to a thickness of 1 μm or more. Before forming a plating film by a step of electroless plating S6, a surface treatment process is conducted on a surface of the base plate composed of a glass material. The surface treatment process comprises at least a step of glass activation treatment S2 to increase quantity of silanol groups on the surface of the base plate at least by a factor of two using an aqueous solution of diluted acid, a step of silane coupling agent treatment S3, a step of palladium catalyst treatment S4, and a step of palladium bonding treatment S5.

A disk substrate for a perpendicular magnetic recording medium is, disclosed. The substrate exhibits sufficient productivity, serves the function of a soft magnetic backing layer of the perpendicular magnetic recording medium, and scarcely generates noise. A perpendicular magnetic recording medium using such a substrate also is disclosed. The disk substrate comprises at least a soft magnetic underlayer formed on a nonmagnetic base plate by means of an electroless plating method. The thermal expansion coefficient of the soft magnetic underlayer is larger than a thermal expansion coefficient of the nonmagnetic disk-shaped base plate. A saturation magnetostriction constant μs satisfies a relation λs≧−1×10−5.
摘要:
A voltage and internal resistance of a battery are measured in advance as its capacity decreases. In a flash memory of a device powered by the battery, voltages necessary to drive a motor, an EL display, and a bezel input unit are stored. By comparing the voltage of the battery with a resistor connected as a dummy load and the voltage read from the flash memory, it can be determined whether it is possible to drive the motor, the EL display, or the bezel input unit.
摘要:
A method for replenishing depleted portions of an ink sheet including a conductive ink layer on a dielectric layer wherein portions of ink have been transferred to a transfer medium. Conductive replacement ink material is supplied to the ink sheet and an electric charge is induced in the replacement ink and opposite charges are induced at an electrode on the opposite side of the dielectric layer. Replacement ink contacting the dielectric layer at the voids will adhere to the ink sheet, but charges in the replacement ink contacting the non-transcribed ink regions will flow to the conductive ink layer and will not adhere to the ink sheet.
