The large cone part (aaa) of the core shaft is cut off by the part where it meets the undercut Q (Jlea) of the rft and qb), so that it becomes a large pole in the pulling direction K of the core shaft. For example, an inclined surface in the dl direction is formed on the #A inclined circle, and this inclined surface is divided into 6 groups, and the slope angle te of each daka-g is set as follows. It is distributed as t. Then, each f@- self is provided with a protrusion (gg) with a tg direction, and the split core attached to the above-mentioned slope is connected to the weight core (gaa) of the cram school/ and the collector core. It is made up of a weight head (lazy) and a large 11:l-n capital (lazy) of the above-mentioned core axis.

The seventh and first weight cores f: The split cores are set at the large diameter part of the core shaft and have an inclination angle of 4 orders of magnitude to create the stroke difference necessary for small diameter operation. 11! At the same time, the first warp and the first part - the close contact of the core I
/c, so that both edges of the split core of Kanko are on both @ edges of the weight core of Juku /, and the front II end of the split core is

After gradually pulling out the plastic vibrator for IM, I realized that I was using a plastic vibrator, and after pulling it out, I made it into an independent structure, and pulled it out. Pull out the core shaft, which is the child's /@power member. From <ilK and 9, the -j! of the gold layer is easy and the assembly operation is simplified, and therefore the formation process becomes 1tK.
