There is provided a weather strip for use on a sunroof which can be firmly built in a seal holder even if there occur variations in molding dimensions. The weather strip comprises a thicker base part which is engaged in a built-in recess of the seal holder fixed to a roof glass, a hollow seal part which elastically contacts a roof panel, and a thinner barrel part which is integrally formed between the thicker base part and the hollow seal part and is clamped by an upper protrusion part and a lower protrusion part which are formed in the built-in recess to protrude therein, wherein a continuous angle between an upper surface of the thinner barrel part and the hollow seal part and that between a lower surface of the thinner barrel part and the hollow seal part are set 90° respectively, and an ascent slope is formed on the upper surface of the thinner barrel part and ascends aslant from the hollow seal part toward the thicker base part, and a descent slope is formed on the lower surface of the thinner barrel part and descends aslant from the hollow seal part toward the thicker base part.

There is provided a weather strip for use on a sunroof capable of preventing squeak noises being generated in advance between a hollow seal part and a roof panel during traveling of a car by allowing the hollow seal part to satisfactorily follow vibrations of the roof panel. The weather strip ensures sealing property between a roof glass mounted on the sunroof of a car and a roof panel and comprises a built-in base part attached to the roof glass, and a hollow seal part composed of continuous ends integrally formed with the built-in base part and having substantially a circular cross section, a tip end contact part elastically contacting the roof panel, wherein thicker parts protruding inward and being continuous with the built-in base part are formed on the continuous ends of the hollow seal part and protrusions protruding inward are formed on substantially middle parts between the continuous ends and the tip end contact part.

This invention provides a method of controlling condition of an assembled battery mounted in a self-generation electric vehicle. The method is comprised of the following steps: detecting battery voltage and battery current repeatedly; estimating a constant-power voltage on the basis of the battery voltage and the battery current; setting a target voltage; comparing the constant-power-discharge voltage with the target voltage to provide a difference therebetween; and charging or discharging the battery to reduce the difference when the battery is not operated. The constant-power voltage is set as a function of a remaining capacity of the battery when a preset constant power is charged to or discharged from the battery.

Described are a thermoplastic polymer composition comprising (A) a block copolymer formed of a polymer block composed mainly of an aromatic vinyl compound and another polymer block composed mainly of isobutylene; and (B) a crosslinked rubber of at least one rubber selected from natural rubber, diene polymer rubber, olefin polymer rubber, acrylic rubber and fluorine rubber at a weight ratio of 90:10 to 10:90; and molded or formed products and hermetically sealing materials produced using the composition. The above thermoplastic polymer composition is excellent in moldability or formability, gas barrier properties, compression set resistance, hermetically sealing properties, sealing properties, flexibility, mechanical properties, oil resistance, safety, hygienic properties and the like. By melt molding or forming of the composition under heat, general-purpose molded or formed products, hermetically sealing materials such as sealant, packing material or gasket, particularly, stopper or gasket for syringe for the medical use can be produced smoothly.

A half-turn hook for positioning a needle thread loop between a needle and a bobbin at the time of stitching, the half-turn hook comprises a shuttle race body, a rotatable shuttle body, a bobbin and a shuttle race ring. The shuttle race body has a sliding surface on which a needle thread is slid in the beginning of stitching. The shuttle race ring has a cutout formed in its upper portion. In the half-hook, the surface where the shuttle body abuts against the shuttle race body and the end into which the rotating shuttle digs, in the cutout of the shuttle body race ring, is located closer to the rotating shuttle body than the sliding surface of the shuttle race body.
