Abstract: Provided is a method for producing a polyurethane (PU) emulsion having good solvent resistance and water resistance and having good compatibility with other aqueous emulsions to give stable mixtures with them. The method comprises reacting (A) a PU prepolymer having an isocyanate group in the molecule, (B) a modified PVA having at least one member selected from the group consisting of an amino group, a primary hydroxyl group and an acetoacetyl group and (C) a low-molecular compound having an amino group and/or a hydroxyl group, in an aqueous medium.

Abstract: The disclosure describes a resin and rubber composition with good heat-shrinkability characteristics. Also described is a resin and/or rubber composition having dispersed therein a metal compound used for heating the composition.

Abstract: A pair of torquer magnets each comprising a cup-shaped yoke is provided with a disk-like permanent magnet and a pole piece. A through-hole provided through the center of the torquer magnet and a spool member made of a magnetic compensating metal is inserted into and fixed in the through-hole. The spool is shaped to have a central portion intermediate its end of a substantially smaller diameter.

Abstract: An emergency lock safety belt retractor is designed to facilitate release from an inadvertent lock-up which may occur after full-speed retraction of the seat belt. This undesired lock-up is due to a latch mechanism which locks a belt spool in response to either excessively abrupt onset of extraction, such as may occur in front-end automotive accidents, or excessively abrupt cessation of retraction. This latch mechanism has two separate latches: a simple latch pawl biased away from its latched position and a more complicated lock wheel. The latch pawl is mounted on a rotary drum and in its latched position engages teeth on a stationary drum. The lock wheel is coupled for rotation with the belt spool but is free to move axially through three regimes. The lock wheel is biased toward a first axial regime in which it couples the rotary drum to the belt spool.

Abstract: An improved safety-belt retractor to be applied to an automotive vehicle or other vehicles for protecting a wearer from danger caused when the vehicle is suddenly or rapidly decelerated. The disclosed safety-belt retractor comprises a frame, a belt reel rotatably disposed within the frame and a safety-belt wound thereon to allow extraction and retraction of a safety-belt, a ratchet wheel with a plurality of ratchet teeth on the periphery thereof being secured on the belt reel, a locking member movably disposed within the frame opposing to the ratchet wheel and being engageable with the teeth of the ratchet wheel, and an inertia sensing means, including a means for operating the locking member, for interengagement of the locking member and the ratchet wheel so as to lock the extraction, when the vehicle is suddenly or rapidly decelerated.
