摘要:
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.

An antenna device for an automobile comprises an electric heating type defogger having heating strips and a bus bar for feeding a current to the heating strips and an antenna conductor having antenna strips arranged to form a pattern, which are fitted on the rear window glass fitted to a rear window opening formed in an automobile, wherein the defogger and the antenna conductor are spaced apart from each other with a predetermined small space in a capacitive coupling relation so a reactance circuit is connected to the defogger to effect anti-resonance between the defogger and the rear window opening of the body of the automobile at the central frequency in terms of logarithmic scale of a broadcast frequency band region; a quality factor value is determined by the inductance of a choke coil in the reactance circuit and the stray capacitance between the defogger and the rear window opening of the body of the automobile so that the ratio of an input impedance to a receiver to the impedance of the antenna conductor viewed from the side of a power feeding terminal becomes 1; and a matching circuit is inserted between the power feeding terminal of the antenna conductor and the receiver so that the sum of the impedance of the antenna conductor viewed from the side of the input terminal of the receiver and the functional part as an antenna in the rear window glass exhibits a little capacitive reactance in a broadcast frequency band region.
摘要:
A pair of cover half members are attached to each other and to a seat hinge base plate in such a manner as to enclose the base plate. The respective cover halves each snap directly onto the base plate at a single point on their lower sides. At their upper sides the covers snap onto each other. The connection between the covers and the base plate is firm but is still resilient enough to allow sufficient movement between the cover assembly and the base plate in the event that large forces or shocks are applied to the cover. The connection between the cover halves is sufficiently strong that forces acting on the cover halves cannot readily force them apart nor cause them to become detached from the base plate.

Performance of heat insulation between the outside of a storage container and the inside of a storage chamber is effectively improved. The storage container includes a container body having an opening, a door member closing the opening in an openable and closable manner, and a temperature-controlled unit having a function of making a temperature inside a storage chamber 2 enclosed by the container body and the door member be different from a temperature outside the storage chamber. The container body includes a first heat-insulating material 14, a second heat-insulating material 15 which is provided partially on the opposite side to the storage chamber 2 with respect to the first heat-insulating material 14 and has thermal conductivity lower than that of the first heat-insulating material 14, and a heat-storage material 16 which is provided at least partially in a region where the second heat-insulating material 15 is not provided as viewed from a thickness direction of the first heat-insulating material 14 on the same side as the storage chamber 2 with respect to the first heat-insulating material 14 and is formed of one or more kinds of raw material where phase transition is caused between a liquid phase and a solid phase at a temperature between the temperature outside the storage chamber 2 and the temperature inside the storage chamber 2 obtained by the function of the temperature-controlled unit.
