摘要:
A water-soluble or water-dispersible pressure-sensitive adhesive composition comprising a sulfonate-containing copolymer obtained from 20 to 99% by weight of an alkoxyethyl acrylate, 1 to 30% by weight of a styrenesulfonic acid salt, and up to 50% by weight of a monomer mixture of acrylic acid-caprolactone adducts. The composition exhibits excellent pressure-sensitive adhesion while showing satisfactory water solubility or dispersibility even in an acidic aqueous solution.

A water-soluble double-faced adhesive tape is provided which needs no release paper, permits web splicing without an increase in thickness at the spliced part, and permits spliced webs to run smoothly in a papermaking process, eliminating the possibility of web breaking. The tape includes a water-disintegratable substrate, a first water-soluble adhesive layer formed on one side of the substrate from one edge of the substrate, and a second water-soluble adhesive layer formed on the other side of the substrate from the other edge of the substrate, the two adhesive layers being positioned a distance apart greater than the web thickness plus twice the tape thickness plus an allowance such that they do not overlap in the width direction, with release layers preventing the adhesive layer from sticking to the substrate when the tape is wound up into a roll.

An aircraft fuel tank capable of suppressing electrostatic charging caused, for example, by flow electrification with the fuel. The aircraft fuel tank comprises an upper skin (5) and a lower skin (7) that exhibit conductivity and form a portion of a container for storing fuel, an internal structure (19) formed from a metal, and an inner surface layer (15) which has semiconductor properties or insulating properties and is formed in an integral manner on the inner surfaces of the upper skin (5) and the lower skin (7) in a location where the internal structure (19) contacts the upper skin (5) and the lower skin (7), and in the surrounding portion thereof, wherein the inner surface layer (15) is formed, at least in the surrounding portion, from a material having semiconductor properties.

A steering control apparatus acquires vibration torque, which is generated by vibration of a gear mechanism when a steering wheel is operated at a steering angle. By setting the acquired vibration torque as a torque difference, an EPS motor current command value is corrected based on the torque difference thereby to calculate a corrected EPS motor current command value. Rattling and vibration caused in the gear mechanism are suppressed from being transferred to the steering wheel through an input shaft so that a driver is released from uncomfortable feeling.

Provided is a sealant applicator which enables an operator to uniformly apply a given amount of sealant to a fastener in a short time regardless of the skill of the operator. The sealant applicator according to the present invention includes: an inner space defined by a substantially cylindrical inner surface that receives a fastener in an axial direction from one end; and a concave-convex portion formed in the inner surface and composed of a convex portion to be located adjacent to the fastener and a concave portion to be located apart from the fastener.

To easily identify the owner of an object currently drawn on a collaboration work area, or an object already drawn thereon, to easily carry out an editing operation for the object of each owner by selectively identifying the object drawn by a particular owner. A user management table registers the node identification code and the owner identifier of a user system therein, and an object management table registers the node identification code and object information therein. Based on an event entry for an object, the node identification code of the object management table is obtained, and the owner identifier of the user management table is obtained. This owner identifier is displayed on a screen by relating it to the object.

A vehicle lamp 10 comprises a light source portion 50 and a plastic decorative member 60 in a lamp chamber 40 constituted by a body 20 and a lamp cover 30 for covering the front of the body. The decorative member has a skin layer 64 and a core layer 65 which are formed by sandwich molding; and the core layer is located in at least a portion that requires heat-resistance in the decorative member and formed of resin material greater in heat-resistance than resin material for the skin layer.

A vehicular lamp having a distance adjustment section that adjusts the distance between the lamp body and the reflector and includes an adjustment shaft, a gear member, and a receiving element. The adjustment shaft has a spherical end; the gear member includes a shaft portion that has the adjustment shaft therein, elastic pawls protruding from the shaft portion, and empty spaces defined by the elastic pawls to allow flexure of the elastic pawls toward the shaft portion; and the receiving element is formed on the back surface of the reflector. The gear member having the adjustment shaft is rotatably inserted in an insertion hole of the lamp body, the elastic pawls are engaged with the edge of the insertion hole to prevent the gear member from slipping out; and the spherical end of the adjustment shaft is engaged with the receiving element and prevented from rotating.
摘要:
In a method of manufacturing a partly flat yoke having curved circumferential walls to which magnets are to be attached and having parallel flat circumferential walls which constitute main magnetic paths and whose each radial thickness is larger than that of the curved circumferential walls, by drawing a sheet of metal plate, the metal plate is held down between a die and projections of a wrinkle preventing plate provided at given angular positions around an outer circumference of a cavity of the die so as to correspond to the curved circumferential walls. Then, a punch presses down the metal plate into the cavity so that material of the metal plate extends axially into the cavity, while the material of the metal plate flows circumferentially from each side of the curved circumferential walls to sides of the parallel flat circumferential walls.
