Abstract: An electrostatic spinning device including a nozzle that sprays spinning liquid that has been charged; a switch that controls spray operation of the spinning liquid; and a housing that includes a bulging portion and a grip portion for grip of the user, the bulging portion bulging outward from a virtual line connecting a tip of the nozzle and an end of the switch on a side of the nozzle, an angle formed by an axis of the nozzle and an axis of the grip portion being 45 degrees or more.

Abstract: A hair holder includes a tube formed of a sheet in such a design as to allow a hair bundle to be inserted from a one-end opening at one end of the tube toward an other-end opening at the other end thereof. The tube includes an integration mechanism in the vicinity of the one-end opening. The integration mechanism is for a clip-type fixing member having a pair of pinchers. The one-end opening is openable and closable by operating the clip-type fixing member having been integrated with the tube.

Abstract: A method of manufacturing a polylactic acid resin injection molded article, having the step (1): a step of melt-kneading a polylactic acid resin composition containing a polylactic acid resin and a specified organic crystal nucleus agent, while contacting the composition with a supercritical fluid; and step (2): a step of filling the melted product obtained in step (1) in a die to mold with injection-molding. The manufacturing method of the present invention is used as an advantageous technique as compared with the technique of achieving satisfactory moldability by the addition of plasticizer in the field, for example, which requires a polylactic acid resin molded article having high rigidity.

Abstract: The tape cassette (10) of the present invention comprises a cassette body comprising an upper half (1) and a lower half (2), and an openable lid (3) provided at the front end of the cassette body. The tape cassette is characterized in that the upper half (1), the lower half (2) and the lid (3) comprise an anti-static resin.

Abstract: The tape cassette comprising a hub, an engagement cavity recessed on the outer periphery of the hub, and a clamper fitted into the engagement cavity, wherein the base end part of a tape is engaged between the engagement cavity and the clamper, and the tape is wound around the hub, characterized in that opposite inner upper edges of the engagement cavity each have first end portions and opposite side edges on a tape winding surface of the clamper each have second end portions facing the first end portions, and each of gaps between the first end portions and the second end portions is dimensioned to be about 0.02 mm to about 0.10 mm.

Abstract: A tape cassette comprising a slider slidably covering a lower half of a cassette main body containing a magnetic tape, a lock element of the slider withdrawably inserted into the lower half surface, a locking coil spring for pressing the lock element, and a retainer portion for retaining the locking coil spring to an upper half, wherein:the retainer portion comprises a spring receiving portion and a retainer wall surrounding the spring receiving portion, said retainer wall having a surface inclined toward the spring receiving portion.

Abstract: A tape cassette of the present invention comprises an upper half and a lower half constituting a cassette body which rotatably contains a hub with a tape wound thereon, a slider disposed in such a manner as to cover the lower half for movement forward and backward, and a spring disposed to a front end portion of the lower half in order to urge the slider forward, a pair of retaining elements each having a projection formed on an outer side thereof being integrally connected to the lower half, the projections being engaged in a pair of first holes or a pair of second holes formed in front and rear portions of the slider to retain the slider urged by the spring, so that a pair of opening portions formed in the lower half can be opened and closed by a pair of opening portions formed in the slider, the height l.sub.1 of a perpendicular surface of each of the projections on the connecting side of the retaining elements being higher than the height l.sub.
