Abstract: A method for producing a bonded body of ceramic and metal bodies includes stacking a ceramic body, metal body, gap layer capable of preventing oxidation and hindering heat conduction, first intermediate layer and second intermediate layer with the gap layer between the ceramic body and the metal body in the stacking direction. The first intermediate layer is between the ceramic body and gap layer, and the second intermediate layer is between the gap layer and metal body, linear expansion coefficients of the first and second intermediate layers being between those of the ceramic body and the metal body. Diffusion bonding is performed between the ceramic body and the first intermediate layer, and between the metal body and the second intermediate layer simultaneously. The gap layer is then removed from between the first and second intermediate layers. The first and second intermediate layers are then bonded to each other.

Abstract: Embodiments of the present invention help to reduce damage of a head element portion or a magnetic disk in a procedure for specifying a heater power value for adjusting a clearance between the head element portion and the magnetic disk. In an embodiment of the present invention, an HDC/MPU sequentially performs data writing and reading while increasing heater power. The HDC/MPU further determines whether or not a head slider has retrieved the data properly. When the data cannot be retrieved properly, the HDC/MPU specifies a heater power value in a normal operation based on the heater power value at which the data could not be retrieved properly.

Abstract: A rotation detector includes a semiconductor chip, a nonmagnetic case body, a biasing permanent magnet and a nonmagnetic cap fixed to the case body, wherein the case body has a joint surface, and the cap has an inside surface in contact with the joint surface. A method of manufacturing the rotation detector includes the following steps: assembling the semiconductor chip, the case body and the biasing permanent magnet into a unit; forming at least one groove adjacent to the joint surface so as to form a space between the joint surface and the inside surface when the cap is fixed to the case body; fixing the cap to the case body so that the inside surface of the cap can be in contact with the joint surface; irradiating a laser beam at portions behind the inside surface of the cap under a prescribed pressure to melt materials of the case body and the cap and to make melted materials flow to the space; and cooling the melted materials to re-crystallize.

Abstract: Acceptance/rejection of a deposition condition is judged by detecting an exothermic quantity of a deposition portion 3 by using an infrared beam sensor 2 during laser deposition of a resin material 4 having transmissibility to a laser beam and a resin material 5 having absorptivity to the laser beam L. The exothermic condition of the deposition portion is detected by using an infrared beam sensor matching with a wavelength of an infrared beam having a high transmission factor from infrared beam transmission characteristics of the transmissible resin to judge whether or not suitable energy is applied to the deposition portion and whether or not the deposition portion is formed. The exothermic quantity of the transmissible resin is detected by an infrared beam sensor 2A to judge acceptance or rejection of the deposition portion even when the applied energy changes.

Abstract: A metal mold is prepared, which has a gate, a cavity in which a virtual curve is formed, which forms at least a welding target part of a laser beam transmitting member along the virtual curve, and in which a filling terminal wall is formed along a curve parallel to the virtual curve, and a throttle part for reducing the flow of a resin flowing from the gate toward the cavity, which is connected to the cavity, and whose connection boundary is formed along a curve parallel to the virtual curve. Then, a resin is injected into the gate and a crystalline laser beam transmitting member is molded out of the injected resin using the metal mold.

Abstract: Embodiments of the present invention help to effectively remove adhesion on a head slider. In an embodiment of the present invention, a hard disk controller/multiprocessing unit (HDC/MPU) raises the temperature on the surface of a head slider with a heating element on the head slider to remove adhesion on the head slider while an actuator stays on a ramp. The HDC/MPU varies the amount of heat in accordance with the temperature sensed by a temperature sensor. This achieves removal of the adhesion on the head slider, maintaining reliability.

Abstract: Embodiments of the present invention help to accomplish accurate and reliable clearance control. In one embodiment of the present invention, a disk drive device adjusts the clearance between a head element portion and a disk with a heater on a slider. The clearance control according to the present embodiment incorporates the variation in heater power efficiency in the clearance variation depending on the radial position. The clearance variation in a unit of heater power varies depending on the radial position. Taking account of the variation in the heater power efficiency in the thermal fly-height control (TFC) depending on the radial position in addition to the clearance variation between the head element portion and the disk caused by variation in fly-height or attitude, accomplishes more accurate TFC.

Abstract: Wiring members such as bus bars for electrically connecting electronic components are contained in a casing composed of a substrate and a cover for closing an opening of the substrate. A laser beam is irradiated on and around solder held in one of the wiring members through a laser-transparent portion formed in the cover of the casing. The solder is melted by energy of the laser beam, and the wiring members are electrically connected by the molten solder. The electronic components and wiring members may be encapsulated in the casing before or after the laser beam is irradiated. Since the laser beam is irradiated from outside the casing after the electronic components and wiring members are contained in the casing, they can be positioned in the casing with greater freedom.
