Abstract: The exterior window film according to the present invention comprises a substrate, a hard coat layer provided on one surface side of the substrate, and a pressure-sensitive adhesive layer provided on the opposite surface side of the substrate from the side provided with the hard coat layer. The hard coat layer is composed of a material containing a (meth)acrylate-based resin having a urethane (meth)acrylate as a constituent component, a hindered amine light stabilizer, and an ultraviolet absorber. The exterior window film according to the present invention is characterized in that, relative to 100.0 parts by mass of the (meth)acrylate-based resin, a proportion of the hindered amine light stabilizer is 2.0 parts by mass or more and 15.0 parts by mass or less, and a proportion of the ultraviolet absorber is 5.0 parts by mass or more and 30.0 parts by mass or less.

Abstract: A lightweight damper pulley is provided which can be produced in a simple manner. The damper pulley includes a central portion, including a cylindrical boss portion to be fixed onto a rotary shaft, a main portion extending radially outwardly from the larger diameter part of the cylindrical boss portion and a central flange bent to extend horizontally from an outer periphery of the main portion. This forms a substantially U-shaped cross-sectional profile. The pulley also includes a belt retaining portion made of metal plate that also has a substantially U-shaped cross section profile. This space is determined between an outer belt supporting wall, an inner belt portion flange and a radially extending connecting wall. The pulley is constructed by reversing the two U-shaped profiles or dissecting the belt retaining flange to the interior of the central flange, with an elastic, damping ring forcefit therebetween. The belt retaining flange can also be moved radially outwardly to compress the elastic.

Abstract: A pulley is made from a metal plate which is easy to manufacture, inexpensive in manufacturing cost, light weight and sufficient strength by using a press forming technique. The pulley has a thin tubular boss portion and a disk shaped body portion which are integral. The boss portion may have a reinforcing flange at one open end portion. The reinforcing flange aids in providing sufficient strength against the tightening force of a nut which is screwed onto a shaft inserted into the boss portion, and also disperses the tightening force. Further, the pulley may have formed integrally on the boss portion a key member.

Abstract: A forging punch of the present invention includes: an outer punch of a cylindrical shape; and an inner punch disposed in the outer punch and protruding from an end surface of the outer punch; at least one of the punches having at least one groove for relieving oil formed either on an inner peripheral surface of the outer punch or on an outer peripheral surface of the inner punch. Therefore, an oil remaining between the end surface of the outer punch and the bottom surface of a workpiece is relieved to the outside of the forging punch by way of the groove, thereby enabling precise forging. Further, the forging punch has obviated additional processing, because no traces of the groove are marked on the workpiece after processing.

Abstract: A hose fitting body composed of a head portion with a through hose made in the center of a pair of flat surfaces thereof, a base portion, and a sleeve is formed out of a test tube-shaped substance by plastic deformation, and a nipple is integrally fixed on the inner circumferential surface of the sleeve. The hose fitting allows for the bending of the base portion while securing a necessary cross-sectional area for the fluid delivery hole of the base portion even when the base portion is bent greatly. The light-weight construction facilitates uniform wall thickness while reducing raw material cost, and provides for fixing the nipple on the sleeve inner circumferential surface in a fluid-tight manner without brazing or drive fitting the nipple.

Abstract: Disclosed are a hose fitting comprising the following and a process for manufacturing the same: A hose fitting body composed of a head portion with a through hole made in the center of a pair of flat surfaces thereof, a base portion, and a sleeve all of which are formed out of a test tube-shaped substance by a plastic deformation, and a nipple integrally fixed on the inner circumferential surface of the sleeve. The hose fitting of this invention provides the following advantages of offering easy work for the bending the base portion, offering readiness for securing a necessary cross-sectional area as the fluid delivery hole of the base portion even when the base portion is bent greatly, light-weighted construction having a uniform wall thickness and requiring less raw material cost, and fixing nipple on the sleeve inner circumferential surface in a fluid-tight manner without brazing or drive fitting the nipple.
