  • Patent number: 10266637
    Abstract: Provided are a polyurethane-modified epoxy resin composition having satisfactory operability of processing, such as casting or impregnation, in a composition state, a production method therefor, and a composition thereof. The polyurethane-modified epoxy resin is obtained by modifying a secondary hydroxyl group-containing bisphenol-based epoxy resin (a) having an epoxy equivalent from 150 g/eq to 200 g/eq and a hydroxyl equivalent from 2,000 g/eq to 2,600 g/eq with a polyol compound (b) having an Mn of 200 or more, a polyisocyanate compound (c), and a polyol compound (d) having an Mn of less than 200 serving as a chain extender. The polyurethane-modified epoxy resin uses the epoxy resin (a) in an amount from 20 wt % to 60 wt % with respect to the total amount of the respective components (a), (b), (c), and (d), and contains a polyurethane having the epoxy resin (a) added to both terminals thereof and/or one terminal thereof.

  • Patent number: 4244550
    Abstract: An umbrella supporting device for detachably supporting an umbrella substantially in an upright position at the center of the handlebar of a bicycle. A supporting post is removably attached substantially in an upright position to the stem of the handlebar of the bicycle. The supporting post is divided into upper and lower post members, the former of which is telescopically received and locked in position in the latter. A clamping mechanism is attached to the upper end of the upper post member so as to detachably clamp the handle of the umbrella. The clamping mechanism has a pair of clamping members, the inner sides of which face each other so as to hold inbetween the umbrella handle. An operating lever or bar is used to bring, when manually operated, one of the clamping members toward the other for the clamping purpose.
