The pear is suffering from pear rust - remove every affected leaf and either burn or put in domestic waste. Also pick up any fallen leaves and do the same. This year has been particularly bad for pear rust and all of my trees have been affected to some extent. The disease has two hosts and overwinters on Junipers, so if there are any of those in your or neighbouring gardens, it'll be back next year.
The raspberry has 'white drupelet disorder' which is thought to be caused by too much sun (UV damage - a bit like sunburn to us) on the fruit, so it could be the position is a little too open and sunny for them (raspberries can take a fair amount of shade and still crop well.) I grow my rows orientated north-south which helps as the canes then shade each other to some extent.
