Abstract: A tracking heliostat array comprises a plurality of optical elements. The tracking heliostat array further comprises a frame separated from the optical elements. Each of the optical elements has an orientation with respect to the frame. The tracking heliostat array further comprises a plurality of supports coupled to at least one of the optical elements. The tracking heliostat array further comprises a turnbuckle coupled to at least one of the supports and to the frame. Rotation of the turnbuckle causes the corresponding support to be displaced relative to the frame. The orientation of the optical element relative to the frame is adjustable. The tracking heliostat array further comprises a traveling actuator configured to rotate at least one of the turnbuckles. The tracking heliostat array further comprises a positioning mechanism supporting the traveling actuator. The positioning mechanism is configured to move the traveling actuator from a first selected turnbuckle to a second selected turnbuckle.

Abstract: A support structure for a magnetic head slider for reading/writing includes: (a) a wiring flexure including: (i) a plate substrate having a distal end and a proximal end and having an opening at the proximal end; (ii) an insulating layer formed on the plate substrate and having at least one through-hole at its proximal end; (iii) a conductor layer formed on the insulating layer; and (iv) a protection layer formed on the conductor layer and having at least one through-hole at its distal end; (b) a load beam having two sides through which an aperture is formed; and (c) an arm having a distal end where the load beam is supported. The wiring flexure passes through the aperture of the load beam and is fixed at a position between its distal end and its proximal end.

Abstract: The present invention provides a process for preparing an aromatic or heteroaromatic thiol represented by the formula (2), the process comprising hydrolyzing an aromatic or heteroaromatic halogenated methyl sulfide represented by the formula (1)Ar.paren open-st.SCH.sub.3-m X.sub.m).sub.n (1)Ar.paren open-st.SH).sub.n (2)wherein Ar is an aromatic or heteroaromatic ring which has no substituent or which has an optional substituent or substituents, X is a halogen atom, m is an integer of 1 to 3 and n is 1 or 2.According to the present invention, an aromatic or heteroaromatic thiol can be prepared at a commercially low cost and with ease.
