That looks like the Sugino font to me.. won't a standard crank-puller remove them?
Here's Sheldon on crank pulling: http://www.sheldonbrown.com/tooltips/cotterless.html
I reckon they're Sugino cranks so that's probably the type you need.
*"Which tool to buy depends on what brand and model of crankset you have. Although all types use the same one- thread-per-millimeter pitch, three common diameters for the dustcap threads: Campagnolo, 22 mm; T.A. 23 mm; and Stronglight, 23.15 mm. All other brands that I know of use the same size as Campagnolo.There is one small exception: early Lambert cranksets were threaded 7/8-inch by 24 threads per inch.)
To service a T.A. crankset, you need a T.A. puller. For Stronglight, ideally, you should have a Stronglight puller, but the T.A. is usable (although it fits a bit more loosely than it should). For any other brand, you have a wider choice available. Here are some things to keep in mind as you shop among the alternatives:
[The above two paragraphs are out-of-date; all modern cranks use the 22 mm "Campagnolo size. Stronglight switched in 1982. TA still uses the 23 mm size for the traditional "Cyclotouriste (5 vis) model only.] Pullers made primarily for Type I cranksets usually have a rotating collar on the end of the "bolt." This collar is the part that actually pushes against the end of the axle to pull the crank off. If you use this type of tool on a Type ll. spindle, it will work, but the threaded end of the spindle may damage the pivot of the tool's collar. Also, some Type I pullers simply don't fit on Type II cranksets: the puller's "nut" may interfere with the threaded boss on the spindle.
Of the tools intended for Type II spindles, the Sugino Maxy crank puller is particularly nice; it includes its own socket wrench. It can be used with a six-inch or larger adjustable wrench, or a 16 mm open end wrench if you happen to have one. The Maxy puller has a dome-shaped end to push against the male threaded end of Type II spindles intended for nuts. When this tool is used with a Type I female threaded spindle, the sides of the "bolt" of the puller rub against the edges of the spindle threads that the crank bolts screw into. There is a slight possibility that the spindle threads could be damaged by this, but bottom bracket spindles are made of such very hard steel that the risk is small."*
