    摘要: A finishing grindstone member (20) is fixed to a spindle (10) by a bolt. In the spindle (10), there is formed a tool mounting portion (25) into which a rough grindstone member can be mounted. Into the tool mounting portion (25), there can be mounted not only the rough grindstone member but also a cover member (36). After a silicone wafer is roughly ground using the rough grindstone member, when finish grinding the silicone wafer using the finishing grindstone member (20), the cover member (36) is mounted onto the tool mounting portion (25) to thereby prevent the tool mounting portion (25) from being soiled.

    摘要: A decolorizable image forming material comprising a color former, a developer and a decolorizer, the decolorizer comprising a highly amorphous phase separation inhibitor and a slightly amorphous phase separation inhibitor. A cyclic sugar alcohol is used as the highly amorphous phase separation inhibitor, and a non-aromatic cyclic compound having five-membered or larger ring substituted by a hydroxyl group or a derivative of a cyclic sugar alcohol is used as the slightly amorphous phase separation inhibitor. The decolorizable image forming material can be decolored easily after image formation by a solvent and the decolored state of which can be maintained stably, thereby making it possible to reuse paper sheets.

    摘要: A workpiece 23 formed of a circular thin plate is rotated about its center as an axis L1. Each of disk-shaped rotating grinding wheels 27 and 28, while being rotated about an axis L3 extending in a direction substantially parallel to the plane of the workpiece 23 and perpendicular to the radial direction of the workpiece 23, is made to undergo relative feeding movement on both obverse and reverse surface sides of the workpiece 23 along an outer peripheral edge portion 23a of the workpiece 23. Consequently, the outer peripheral edge portion 23a of the workpiece 23 is ground by an outer peripheral surface of each of the rotating grinding wheels 27 and 28. In this case, it is preferred that two grinding wheels 27 and 28 for rough grinding and finish grinding be provided as the disk-shaped rotating grinding wheels, and that rough grinding and finish grinding are performed by the same station.

    摘要: A developing method for converting an electrostatic latent image on the surface of an electrostatic latent image holder into a visible image by arranging the electrostatic latent image holder for holding the electrostatic latent image thereon and a toner conveyor for conveying non-magnetic one-component type toner thereon an extremely small space apart from each other; applying the non-magnetic one-component type toner onto the toner conveyor; and transferring the toner to the electrostatic image holder, satisfies the following requirements: the aforesaid developing agent is composed of non-magnetic type toner; the frictional charge quantity relative to the surface of the non-magnetic type toner is +30 100 .mu.C; and fluidity is 5 g or less in terms of the toner amounting to 20 g but remaining on a 100-mesh sieve after it has been vibrated at a rate of 3,000 V.P.M. and an amplitude of 1 mm for 30 seconds. The non-magnetic one-component type toner may positively charged non-magnetic one-component type toner at least containing resin and a coloring agent, the resin satisfying the following requirements: the glass transition point is over 50.degree. C.; the softening point is within the range of 110.degree. C.-160.degree. C.; and the frictional charge amount relative to the surface area is within the range of 25.about.150 .mu.C/m.sup.2. The non-magnetic one-component type toner may be prepared by treating the surface of toner containing binder resin whose glass transition point is over 50.degree. C., and whose softening point is within the range of 110.degree..about.160.degree. C., and a coloring agent with a silane coupling agent having an amino group.According to the above method, development fog and the scattering of the toner are prevented so that a visible image of good quality can be formed.
