Abstract: A speaker diaphragm includes a first polymer and a second polymer. The first polymer and the second polymer undergo phase separation. The first polymer is a polyolefin, and the second polymer is a thermoplastic resin being immiscible with the polyolefin. One of either the polyolefin or the thermoplastic resin constitutes a sea phase, and another one of either the polyolefin or the thermoplastic resin constitutes island phases being interspersed in the sea phase.

Abstract: A liquid-cosmetic applicator is provided having a wiper formed on the inside of an elongated opening of a liquid-cosmetic container for scraping off the liquid cosmetic that adheres to the stem of a stemmed brush. The wiper includes at least two wiper domains that overlap along the longitudinal axis of said opening, each domain having a scraping section at one axial end, and a non-scraping section at an opposite end, the scraping sections being axially offset from one another and having sides that mutually engage along at least one interface. The interface provides a gap between said stem when said stem of said brush engages said scraping sections of said wiper domains that in turn defines an air passage that allows air to axially flow through said wiper as said stem is being wiped thereby eliminating unwanted suction forces when the applicator is withdrawn from the container.

Abstract: A liquid-cosmetic applicator capable of avoiding pumping phenomenon without lowering the scraping function of its wiper is provided. The liquid-cosmetic applicator has a wiper (15) formed on the inside of an opening (12) of a liquid-cosmetic container (10) for scraping off the liquid cosmetic (13) that adheres to the stem (36) of a stemmed brush (30). The wiper has an axially offset region occupying a certain peripheral domain of the wiper and an axially non-offset region occupying another peripheral domain including another scraping section. The offset region and non-offset region include scraping sections (17A, 17B), respectively, that overlap in the axial direction, leaving a gap formed between, and along the peripheries of, the overlapping scraping sections (17A, 17B).

Abstract: Deep drawing of a work can be made by securing a certain amount of feed of the work from the side of a cushion ring to a vertical wall surface of a stationary die. In this drawing method, for the drawing of the work, a die part interlocked to a movable die is engaged in a recess of the stationary die in a direction different from the direction of pushing. An edge of the work is displaced in unison with the cushion ring and the movable die clamping it in cooperation, and the die part starts to push the work immediately before the instant when the work located in the vicinity of the cushion ring is brought into contact with the edge of the recess of the stationary die. The resistance of contact between the work and the stationary die thus is not increased in the vicinity of the cushion ring when the die part pushes the work, and a certain amount of feed of the work from the side of the cushion ring can be secured.
