摘要:
A solar energy collector device is disclosed for selectively collecting an electrical energy and a thermal energy at the same time from a solar energy. The device comprises an inorganic-and-metal composite in the form of a roof tile or a wall-forming member which includes a solar battery exposed to sun rays and a heat medium passageway disposed underneath the battery. The density of distribution of a particulate inorganic substance within a metal mass is varied through the areas of the tile or wall member so as to effectively collect the respective energies without adversely affecting the interior conditions of a building in which the device is installed.

A tack member, which is adapted to be joined with a button body for attachment of a button to a garment fabric, has a shank composed of a tapering end portion and a stem portion. The shank has a cold-pressed recess near the tapering end portion. The tapering end portion is in the shape of a pyramid with its tip end disposed off the axis of the shank toward the recess so that the tapering end portion is bendable about the recess as its tip end is forced against the inner side of a cap of the button body during insertion of the shank into a hollow hub of the button body, during which time the stem portion opposes bending or other deformation.

A capped eyelet, for attachment of a snap fastener member to a garment fabric, comprises an eyelet body including a shank with a flange, a cap covering over the flange and secured to a periphery thereof, and at least one punched buffer wing projecting from the flange and having at least one rib. The buffer wing is resiliently deformable to absorb an endwise force applied to the shank when the eyelet is axially compressed for being joined with a snap fastener member. At that time the rib is engageable with the upper end portion of the shank to assist in absorbing the riveting force.

A stamping apparatus disclosed deforms a filamentary material to provide coupling heads and the like at predetermined intervals along the length of the filament which is to be coiled and attached to stringer tapes for a slide fastener. The apparatus includes a pair of stamping rolls which are rotatable in opposite directions on their own axes simultaneously as they orbit about the axis of a rotor. A ring member rotatably connected to the stamping rolls is driven via the same power source as the rotor but rotates at a slower or faster angular speed than the rotor, the resulting angular speed differential being utilized to effect the rotation of the stamping rolls on their axes.

A slide fastener is provided which comprises a pair of oppositely disposed stringer tapes each carrying along its longitudinal edge a series of uniformly spaced fastener elements. Each of the fastener elements has a pair of openings in the rounded front end face of its coupling end portion, and a pair of lugs on the shoulders of its neck portion. The lugs are complementary in shape to the openings and so disposed as to snugly fit in the corresponding openings of adjacent fastener elements of the companion stringer tape when the fastener elements on the tapes are coupled together.

There is provided a slide fastener having a pair of oppositely disposed carrier tapes each carrying on and along one longitudinal beaded edge a series of discrete fastener elements. The fastener elements are each provided with a coupling head and a pair of legs extending from the coupling head and having oppositely disposed inner wall portions. There are formed a plurality of ledges integral with the element legs and projecting from the oppositely disposed inner wall portions. The ledges are smaller in thickness than the element legs.

A method of forming a chain of meandering or zig-zag coupling elements for slide fasteners includes dividing or bifurcating a continuous length of substantially cross-sectionally circular monofilamentary material axially into identical halves of substantially semi-circular cross-section immediately prior to introduction to a forming apparatus. The identical halves may be provisionally joined together to provide a cross-sectionally circular monofilament and divided back into respective halves immediately prior to formation thereof into respective rows of coupling elements for slide fasteners.

A hook for a hook-and-eye fastener includes a one-piece hook body having at least one pair of prongs, and a retainer having openings through which the prongs extend, respectively. The hook body includes a locking tongue and a base underlying the locking tongue, and an arcuate portion joining the locking tongue and the base, the prongs projecting substantially perpendicularly from the base in a direction away from the locking tongue. The hook body has a plurality of cold-pressed elongated recesses defined in an inner surface of the hook body and extending from the base through the arcuate portion to the locking tongue, thereby giving resilience and strength that are large enough to withstand forces tending to permanently deform the hook body at the arcuate portion. The openings in the retainer are spaced from one another by a distance which is larger than the distance between the prongs. Each of the prongs has a bent end portion retained on the retainer with a space defined therebetween. With the hook thus constructed, the hook body is tiltable with respect to the retainer, thereby accomodating the thrust applied thereto during, for instance, the ironing of a garment fabric to which the hook is attached.

A metal strip including an elongate web and a pair of longitudinal medial lands on both sides thereof, is successively stamped or coined so as to be provided with a series of coupling elements each including on each of its both sides a transverse projection and a pair of longitudinal teeth one on each side of the projection, the projection being higher than the teeth. The projection and teeth are formed from material of the medial lands and additionally from material of a portion extending all the way around the projection and teeth, which is thinned down to a thickness smaller than that of the web. Then, the metal strip is notched along its marginal edges to provide the outer profile of clamping legs, and is severed into individual coupling elements.

A concealed sliding clasp fastener is described, which fastener is provided with an adjustable end stop movably mounted on interengaged rows of coupling elements and positioned between a slider and a permanently secured bottom stop. The adjustable end stop may be secured by clamping or by fusion to adjacent coupling elements at any desired position on the fastener, after the latter is applied to a garment.
