A terminal arrangement of a motor has a terminal base formed with a plurality of terminal pins, the terminal base being fixed detachably on a stator iron core of a motor, terminal pins formed on bobbins, connected electrically with windings wound around the bobbins, a printed circuit board arranged on the stator iron core so as to connect electrically the terminal pins formed on the bobbins with the terminal pins formed on the terminal base, and an end bracket arranged so as to cover the printed circuit board. A hole is formed in the stator iron core, and an earth electrode is projected from the terminal base, and inserted into the hole so as to be connected electrically with the stator iron core, the earth electrode being connected electrically to one of the terminal pins formed on the terminal base. A capacitor motor has a motor having a stator iron core, and a phase advancing capacitor fixed detachably on the stator iron core.

Disclosed is a coating composition for PC tendon, which is applied on surface of the PC tendon. This composition includes epoxy resin, multifunctional isocyanate compound, calcium oxide and water, and further includes water-absorbing polymer as necessary. A curing time thereof is adjusted so that tensioning by the PC tendon can be exerted 30 days or later after casting of the concrete. Accordingly, even when applied to a massive concrete structure, the coating composition enables effective tensioning after hardening of the concrete, while exhibiting excellent storage stability.

An apparatus for producing a web of continuous fibers having a melt extruder, an endless belt running in one direction and a guide box located between the extruder and the belt. The guide box has front and rear walls as viewed in the running direction of the belt, a pair of side walls extending between the front and rear walls and upper and lower end openings. The fibers extruded from the extruder enter the upper end opening by suction exerted in the vicinity of the lower end opening. The guide box is formed in the front wall and/or the rear wall with intermediate opening(s) serving to introduce the outside air into the guide box.

A method for boring a well with a laser beam is provided, the method comprising: shining the laser beam into a conduit, wherein the laser beam is guided through the conduit by the internal reflectivity of said conduit; and extending the conduit into the well, so that the laser beam exiting the conduit shines onto an area in the well to be bored. A system for boring a well with a laser beam is also provided, the system comprising: a means for shining the laser beam into a conduit; wherein the laser beam is guided through the conduit by the internal reflectivity of said conduit; and a means for extending the conduit into the well, so that the laser beam exiting the conduit shines onto an area in the well to be bored. An apparatus is provided as well, comprising a conduit that is extendable into the well, and an inner surface inside of the conduit, wherein the inner surface is reflective to the laser beam.

The present invention prevents production of residue which causes short-circuit between word lines. A memory cell comprises a channel formation region CH, charge storage films CSF each comprised of a plurality of stacked dielectric films, two storages comprised of regions of the charge storage films CSF overlapping the two ends of the channel formation region CH, a single-layer dielectric film DF2 contacting the channel formation region CH between the storages, auxiliary layers (for example, bit lines BL1 and BL2) formed on two impurity regions S/D, two first control electrodes CG1 and CG2 formed on the auxiliary layers with dielectric film interposed and positioned on the storages, and a second control electrode WL buried in a state insulated from the first control electrodes CG1 and CG2 in a space between them and contacting the single-layer dielectric film DF2. Since the main regions on facing surfaces of the first control electrodes CG1 and CG2 become forward tapered, conductive residue is not left at the time of processing the second control electrode WL.
