The present invention uses lithographically patterned graphite stacks as the basic building elements of an efficient and economical photovoltaic cell. The basic design of the graphite-based photovoltaic cells includes a plurality of spatially separated graphite stacks, each comprising a plurality of vertically stacked, semiconducting graphene sheets (carbon nanoribbons) bridging electrically conductive contacts.

A seed firming assembly is mounted to a planter by a bracket attached to a seed tube guard between a pair of opener disks. The bracket has first and second sides that define a cavity therebetween for receiving a seed tube. A first mounting structure in front of the cavity secures the bracket to the seed tube guard. A second mounting structure behind the cavity attaches a seed firmer to the bracket with a pivot connection that allows rotation of the seed firmer relative to the bracket about a generally horizontal transverse axis. A stopper bushing limits an extent of forward pivoting of the seed firmer relative to the bracket, and an adjustable tensioner mechanism limits an extent of rearward pivoting. The seed firmer has an upper portion comprising a leaf spring, and a lower portion comprising a material that has a higher abrasion resistance than the upper portion.

A strap system for selectively and independently binding and/or releasing at least one sets of essentially longitudinal objects, such as wires, from one another. A continuous strip of such two-sided material may be stored on a reel and is designed so that a user may select a preferred length and configuration for a particular use by making a single cut of the material strip from the reel-strip end.

An electrical connector (10) includes an insulative housing (11), and a multiplicity of electrical contacts (12) received in the housing. Each contact comprises a retaining body (13) engagingly received in a corresponding passageway (110) of the housing, a soldering portion (14) extending from a bottom end of the retaining body for soldering to a PCB (40), and a resilient arm (16) extending from a lateral side of the retaining body. The resilient arm has a curved beam (162) extending slantingly upwardly and protrudes out from a top surface of the housing. An enlarged contact portion (164) is defined at a distal end of the curved beam. A width of the contact portion is substantially three times a width of the distal end of curved beam. The contact portion resiliently electrically contacts a metal contact pad of a CPU, thereby electrically connecting the CPU with the PCB.

There is disclosed a honeycomb structure manufacturing method which is capable of efficiently and inexpensively manufacturing a honeycomb structure for preferable use in a filter for trapping particulates in an exhaust gas or the like by use of a long-life grinding member whose satisfactory grinding performance is retained for a long time. The method includes the step of: working an outer periphery of a coarsely shaped honeycomb structure 20 made of a porous ceramic by use of a grinding member 10 to obtain a honeycomb structure 30 having a predetermined shape, wherein diamond abrasive grains of the grinding member 10 have a grain size of 40 to 150 mesh (JIS B 4130 standard) and a concentration degree of 80 or more, and the surfaces of the diamond abrasive grains are coated with at least one selected from the group consisting of Ti, Ni, and Cr.

A method of making spherical bodies from powder, which comprises (1) preparing an adjusted powder so as to have at least one powder characteristic selected from the group consisting of an average particle size, a powder particle size distribution and a BET specific surface area, (2) preparing nuclei having a particle size larger than that of the adjusted powder, (3) rotating the nuclei, and (4) adding the adjusted powder and a solvent to the rotating nuclei so that particles of the adjusted powder accumulate on the nuclei to form granular bodies. Also disclosed is a spherical body having a core or nucleus formed in the spherical body, an adjusted powder composition for forming a spherical body, and a method for manufacturing spherical sintered bodies of silicon nitride.

A method of manufacturing a resin molding according to the present invention is made by joining first and second resin molded parts. The method includes molding a concave portion when molding the first part, molding a convex portion which has a through-hole in a central portion thereof when molding the second part, mating the concave portion with the convex portion so that a cavity being in communication with one end of the through-hole is configured between the concave and convex portions, holding, with a jig, the first and second parts which the cavity is configured therebetween, connecting a tip of an injection nozzle for injecting a molten resin into the cavity with the other end of the through-hole, and filling the molten resin into the through-hole and the cavity from the injection nozzle so that the concave and convex portions are integrally joined by the resin.

The present invention provides a thermal transfer image receiving sheet having a good productivity, capable of inexpensively obtaining an image with high density and high resolution. A dye receiving layer is provided on one surface side of a base material film, and a porous layer with hollow particles bonded by a binder resin provided on the other surface side, respectively. The porous layer is attached with a base material via an adhesive layer.

A portable curling iron holder is disclosed utilizing inexpensive thermoplastic molded to form a caddy. The holder incorporates a thermally resistant insert placed into and securely attached within one of the cavities of the caddy. This insert would be sized to receive and retain the heated barrel of a curling iron while providing a thermally insulative gap between the heated barrel of the curling iron and the adjacent thermoplastic walls of the caddy.

A latch assembly for insertion into an edge of a door and adjustable for actuation by a half-round spindle at either a first backset or a second backset. The latch has an inner casing non-rotatably received within an outer casing and slideable along an axis. The inner casing is provided with a transverse void substantially perpendicular to the sliding axis and is slideable between a first position in which the transverse void is aligned at the first backset and a second position is which the transverse void is aligned at the second backset. A slide within the casing is, without adjustment, engageable by the half-round spindle at either backset. A cam is rotatably mounted within the casing and engaged to the slide and to a bolt also within the casing. The bolt is slideably retractable into the casing by rotation of the cam in response to sliding of the slide. A spring biases the bolt to an extended position extend out from the casing.

The invention involves an improved wire spool guide including a frame that comprises adjacent legs for coupling with a support rod that typically traverses the center of a wire spool hub. Each leg includes a terminal end comprising a spring arm and rod-registering area configured to capture a portion of the rod while allowing the rod to rotate therein. In exemplary embodiments, each leg extends from an anterior support of the frame that is roughly perpendicular to both legs. A wire-guiding element extends substantially form a center portion of the anterior support. The wire-guiding element may be defined by a helical structure configured for allowing a portion of the wire to be weaved into the helical structure rather than having to be threaded through. The helical structure may include an incongruous element, which prevents the wire from tangling at an exit point of the wire-guiding element.

The present invention relates to a paper towel that can be provided with dry crepes with no need for involving a large equipment investment. The paper towel contains one or more of chemical pulp, mechanical pulp, de-inked pulp, and recycled pulp, being provided with crepes in an off-machine process by use of a microcreper, such as a MICREX®/Microcreper™ system, and having a basis weight of 32.2 to 64.3 gsm, a density of 0.130 to 0.150 g/cm³, which is obtained by dividing the basis weight by the caliper (μm), and the number of crepes (cpi) of 12 to 30.
