A pickup actuator includes a slider, an optical pickup unit, and at least one suspension arm extending from the slider for suspending the pickup unit. The pickup unit includes at least one bobbin surrounding a yoke plate, upon which a first coil is wound, and further transversely mounted coils attached to the first coil. The coils collectively control movement of the pickup unit in tracking, focusing and tilt directions thereof. A further bobbin connected to the slider surrounds the yoke plate and includes a further coil wound thereabout for driving the slider and the pickup unit radially of an associated optical disk.

A manufacturing system in which the automatic control of the system and the automatic control of a process management are organically coupled, thereby to sharply reduce the number of workers to be engaged in the manufacture. In order to establish both the versatility necessary for multiple type of treatment and the high efficiency necessary for large-quantity treatments, the arrangement of respective treatment sections is made the job-shop-type, and the construction of treating devices themselves included in the treatment sections is made the flow-shop-type, to achieve the consecutive automation. In order to also automate the management of the process, a stocker in which unfinished products are put is situated in a specified place of the system such as the central part thereof, while the process is put forward in such a manner that a conveyor machine controlled by a control unit having a computer reciprocates between the stocker and the groups of treatment sections. The manufacturing system is suitable for the fabrication of semiconductor devices which have many kinds of articles where each kind of article needs to be mass-produced.

A wire bonding system connects wires between electrode pads on a semiconductor pellet fixed on a lead frame to the corresponding lead parts on the lead frame. The lead frame with the pellet fixed thereon is first set in a position beneath a projector, to obtain a magnified image of the pellet, from which the position of the pellet is measured. On the basis of the measured value, a computer calculates positions for bonding the wires. The lead frame with the pellet therein is then set on the wire bonding machine and the positions of the bonding head are controlled using the result of said calculation to carry out wire bonding. The position measuring means is separate from the bonding machine, with an on-line or off-line connection therebetween.

To provide an anode, corrosion-protecting structure of a concrete constructions using this, and a corrosion protection method capable of protecting electrical corrosion, with little generation of gas due to electrolysis of water or chlorine compounds, by decreasing as far as possible the amount of processing performed on the structural body in on-site construction work and suppressing the voltage that is conducted therethrough to a low level. [Solution] A corrosion-protecting structure (1) is constituted by attaching an anode (10) to the surface layer (3) of a corrosion-protecting body (4) through a first electrolyte layer (12) on one face of a conductive layer (11) formed as a sheet. The electrolyte is formed as a sheet. The first electrolyte layer (12) having adhesiveness is attached to the conductive layer (11) and the surface layer (3) of the corrosion-protecting body (4).

Virtual Functions (VFs) 602-1 to 602-N of an I/O device are separately allocated to a plurality of computers 1-1 to 1-N. In an address swap table 506, a root domain that is an address space of the computer 1 and mapping information of an I/O domain that is an address space unique to the I/O device 6 are registered. Mapping is set with the VFs 602-1 to 602-N as units. When accessing the VFs 602-1 to 602-N of the I/O device 6 to which each of the computers 1-1 to 1-N is allocated, an I/O packet transfer unit 701 checks the address swap table 506 to swap source/destination addresses recorded in packet headers.

A reflective film laminate is provided with high productivity and at low cost in which a protective film with minimized pinholes is provided to improve the alkali resistance and warm water resistance of the reflective film laminate including a pure Al film or an Al-based alloy film so that a reflectivity reduction resulting from the elution or oxidization of the Al film in an alkaline or warm water environment is less likely to occur. The reflective film laminate of the present invention includes, over a substrate, a pure Al film or an Al-based alloy film as a first layer, and an oxide film of a metal containing one or more elements selected from the group consisting of Zr, Cr, Y, Nb, Hf, Ta, W, Ti, Si, and Mo as a second layer over the first layer. The thickness of the second layer is 0.1 to 10 nm.

Provided is a fuel cell separator that can maintain a low contact resistance for a long period of time while being used for a fuel cell, by using a carbon film that can be formed with high productivity. The fuel cell separator 10 is provided with: a substrate 1 comprising titanium or titanium alloy; and a conductive carbon layer 2 that is formed by compression bonding carbon powder onto the substrate 1, and covers the surface thereof. Between the substrate 1 and the carbon layer 2, particle-like titanium carbide 31 and carbon dissolved titanium 32 generated by reacting the titanium of the substrate 1 and carbon of the carbon layer 2 with each other through heat treatment are connected, forming an intermediate layer 3.
