Abstract: Provided are a receiver and a method for detecting a signal in a multiple antenna system. The receiver includes a filter coefficient calculator and a signal detector. After separating a first signal portion and a second signal portion, the filter coefficient calculator calculates an MMSE filter coefficient using a Matrix Inversion Lemma such that an inverse matrix of the first signal portion has a predetermined constant value regardless of a repetition signal detection process. The signal detector detects a relevant transmission signal from an interference-removed reception signal using the MMSE filter coefficient.

Abstract: A tubeless tire is embedded with elliptical cylinder-shaped elastic members. The tubeless bicycle tire has a multiple number of elliptical cylinder-shaped elastic members arranged at regular intervals along the circular tubeless tire and extends through to sides of the tubeless tire. The major axis of each elastic member is fixed integrally with the tire member, being arranged in a radial direction toward a rotational axis of the tubeless tire. The tire is reinforced with elastic force of the elastic members. The tire does not excessively flatten by a load at the portion of the tire touching the road. After leaving the road, the tire restores its original form swiftly by combined elastic force of the tire and elastic rebound of the elastic members. The tire does not flatten again before it restores its original form. The tire produces a safe and longer life free from puncture.

Abstract: A container (10), which holds a molding material (12), is attached to a mold. The molding material passes from the container to the mold through an orifice (18) during the molding process. The container is gradiently heated with the hottest part of the container near the orifice, the heat gradually decreasing towards the opposite end of the container. The hotter molding material deforms faster than the cooler material and as the plastic is forced into the mold, the air escapes past the molding material along the container walls in the direction of the cooler material. A mechanism (16), preferably a narrow ram having a slightly conical shape (22), forces the molding material into the mold. The conical shape allows the air to pass by the mechanism out the end of the container opposite the orifice.
