Abstract: This invention relates to a hair increasing device that improves the freedom of hair styles and, is constituted in such a manner that each hair is knotted to a rib constituting a hair-secured frame with one end portion being twice wound, and the other end portion being once wound and pulled out thereafter. The one end portion of the tied hair is supported so as to stand upright with regard to a rib, and the other end portion is knotted so as to extend longitudinally on and along a rib, and thereby hair flow is formed in the longitudinal direction on a plurality of ribs so that the plurality of ribs is covered and hidden, and becomes hardly visible. Hence the rib or wig base linear member is hardly visible, the knot does not loosen, and the hair increasing device provides a rich voluminous appearance and allows versatility of hair styles.

Abstract: A hair increasing device 10, of which a linear member is hardly visible, a knot does not tend to loosen, and freedom of hair styles is improved, is constituted in such a manner that each hair 12 is knotted to a rib 11b constituting a hair-secured frame 11 with one end portion 12a being twice wound, and the other end portion 12b being once wound and pulled out thereafter. Said one end portion 12a of the tied hair is supported so as to stand upright with regard to a rib, and said other end portion 12b is knotted so as to extend longitudinally on and along a rib 11b, and thereby hair flow is formed in the longitudinal direction on a plurality of ribs 11b so that the ribs 11b is covered and hidden, and becomes hardly visible.

Abstract: A wig base (11) has a first base (12) and a second base (13), wherein the first base (12) has a front portion (12a), a left side portion (12b), a right side portion (12c), a back portion (12d), and a top portion (12e), and is formed in the convex shape resembling the wig wearer's head shape so as to cover a wig wearing region, wherein the second base (13) is extending belt-like in the head shape to the left and right side portions (12b, 12c) from the back portion (12d) on the reverse side of the first base (12) along its outer periphery, and wherein the back portion (13a) of the second base portion (13) is fixed on the reverse side of the back edge portion (12D) of the first base (12), while the left and right side edge portions (12B, 12C) of the first base (12) and the left and right side portions (13B, 13C) of the second base (13) are detachable by attaching parts (16a, 16b), and the wig wearer can wash his or her scalp while keeping the wig on by rolling up the front side of the wig from the front portion

Abstract: A wig (19) is obtained by making a bundle of a plurality of strands of hair (1) of about same length, stretching the whole bundled hair to the pre-determined length by shifting the bundled hair in the length direction to random length, assuming the length of the stretched hair bundle as an apparent total length, forming a bent portion (5) of hair at the half position of said apparent total length, and by attaching said bent portion (5) to a wig base (18). Since the position of the bent portion (5) of hair (1) differs from each other, and the length (A) from the bent portion (5) to one end and the length (B) from the bent portion to the other end are configured to differ for each hair, the finished state of the wig can offer a good natural appearance as if the wearer's own hair were grown.

Abstract: The present invention is to provide a moisture-permeable material for wigs superior in moisture permeability, helping to suppress sweatiness when worn, and allowing easy attachment. A moisture-permeable material for wigs formed in a three-layer structure, including: a core material made of a porous polyurethane; a net layer provided on a side of the core material to be brought into contact with a head and formed of synthetic fibers or natural fibers; and a fiber layer which is laminated on the other side of the core material, which is formed of the synthetic fibers or the natural fibers, and in which artificial hairs or natural hairs are to be planted.

Abstract: A hair material for a wig is preliminarily curled and then bound to a wig base to thereby orient the curled hair in a definite direction. A folded part (10c) of a hair material (10) is penetrated from one side of a filament (15) to the other side under a wig base (12) so that a first loop (17) is formed in the inner side of the folded part (10c). A curved part (10d) is inserted though the first loop (17) so that a second loop (19) is formed in the inner side of the curved part (10d). A part (10b) of the hair material is inserted through the second loop (19). Next, the hair material parts (10a, 10b) are pulled in directions opposite to each other and tied with the filament (15) to (20). Thus, the hair material (10) is bound to the filament (15).

Abstract: An adhesive for a wig, a wig using the same, and methods of manufacturing the both are such that the adhesive for a wig has a single layer, is bondable unpeelably to the inner side of a wig base, and is bondable by pressure re-peelably to scalp, wherein the adhesive layer (4) is provided to fix needle foot portions of hair (3) penetrated to the inner side of the wig base (2). One side of the adhesive layer (4) is bondable by chemical reaction to the inner side of the wig base (2) during gelation reaction of the adhesive solution applied to the inner side of the wig base (2), while the other side is bondable by pressure re-peelably to scalp. One side of the adhesive layer (4) has the hair fixing function to fix the needle foot portion of hair (3A) planted penetrating the inner side of the wig base (2). Since the wig (1) is made as double layer structure with a single adhesive layer (4), it is light-weighted, and since the adhesive layer (4) has re-peelability, it can be used repeatedly, resulting in low cost.

Abstract: A body activity measurement device is provided with a light irradiation unit that irradiates near infrared light of a specified wavelength on a specified measurement site of a brain of a subject; a light detector that detects the intensity of the light exiting from the measurement site; a light absorbance data generator that from the time sequence changes of the intensity of the exiting light generates light absorbance time sequence data suggesting the changes in the concentration of oxyHb, deoxyHb and totalHb; and multiple baseline correction units that correct baselines that mutually differ in relation to the light absorbance time sequence data obtained when the subject performs specified assignments; and configured such that the baseline correction of the light absorbance time sequence data can be conducted using the baseline correction units corresponding to the assignment performed by the subject.

Abstract: By determining the total tying amount of the hair to be short hair 3 and long hair 4 to a wig base 2 to a pre-determined density, and further determining the tying ratio of short and long hairs 3 and 4 to the pre-determined ratio, after tying long hair to be short hair first to a wig base 2 in said pre-determined ratio, and cutting to a pre-determined length to make short hair 3, and next tying long hair to be long hair 4 among the tied short hair 3, and cutting to a pre-determined length to make long hair 4, short and long hairs 3 and 4 can be tied in the pre-determined hair amount, and moreover, short and long hairs 3 and 4 can be tied by controlling to the pre-determined mixing ratio, thereby a wig of a rich bulkiness owing to standing of long hair 4 supported by short hair 3 can be obtained.
