The invention provides a laminate of an inorganic layer, a resin layer, and a coupling agent treatment layer interposed therebetween, which different delamination strengths between the inorganic layer and the resin layer to form a prescribed pattern. The invention also provides a production method comprising (1) treating an inorganic layer with a coupling agent; (2) performing a patterning process to form strong adhesion sections and easily separated sections; and (3) forming a resin layer by drying and heat-treating a coated solution layer obtained by coating a resin solution or a resin precursor solution onto the surface of the inorganic layer that was treated with a coupling agent and then patterned.

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.

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.

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.

A semiconductor chip is positioned between encapsulating sheets. The encapsulating sheets each have a surface that is highly adhesive and a surface that is less adhesive. The surface of the encapsulating sheet that is highly adhesive contacts the chip. The surface that is less adhesive contacts a mold. Subsequently, encapsulation is carried out by molding. A soldering resistance can be improved without reducing a mold releasing property.

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.

The invention provides a laminate of a substrate, a polyimide film, and a coupling treatment layer interposed therebetween, which provides different delamination strengths between the substrate and the polyimide film to form a prescribed pattern. The invention also provides a method for producing such a laminate formed from at least a substrate and a polyimide film, whereby, using a film obtained by plasma treatment of at least the surface facing the substrate as the polyimide film, coupling agent treatment is performed on at least one of the surfaces facing the substrate and the polyimide film to form a coupling treatment layer, deactivation treatment is performed on a portion of the coupling treatment layer to form a pre-determined pattern, and then pressing and heating are performed with the substrate and polyimide film overlapping.
