摘要:
A latent image comprising a first substance formed on a substrate of a second substance having a surface tension different from a surface tension of the first substance, the first substance and the substrate having a difference of 0.1 to 100 nm in height from each other. The latent image is formed by a method comprising the-step of subjecting a substrate of a first substance to a chemical treatment or a physical treatment to form a surface of a second substance which has a surface tension different from a surface tension of the first substance and has a difference of 0.1 to 100 nm in height from the substrate on part of the substrate. The latent image is developed by a method comprising the steps of contacting a latent image comprising a first substance formed on a substrate of a second substance having a surface tension different from a surface tension of the first substance with a third substance different from the first substance and the second substance, and applying a developing ray to the latent image.
摘要:
A method for forming a molecular film includes the steps of: coating a surface of a substrate having active hydrogen atoms on its surface with a coating solution containing a silane-based compound having at least one reactive group selected from the group consisting of a chloro group, an alkoxy group and an isocyanate group; and effecting an elimination reaction between the active hydrogen atoms on the surface of the substrate and reactive groups of the silane-based compound, thereby covalently bonding the silane-based compounds to the surface of the substrate. The substrate is supplied to a chamber in which an atmosphere is maintained at a low water vapor density. The surface of the substrate is coated with a coating solution containing the silane-based compound and a solvent by using a transfer element. A dehydrochlorination reaction is effected between the active hydrogen atoms and the chloro groups of the silane-based compounds. Thereafter, any coating solution containing unreacted silane-based compounds after coating is removed inside or outside the chamber.

摘要:
A thin film composed of a silane-based compound comprising an alkyl group or a fluoroalkyl group is bonded to the surface of an electrically insulating substrate through a covalent bond, thus obtaining an electrically chargeable substrate maintaining a charged state for a long time regardless of relative humidity of an atmosphere. A glass plate for placing a sheet in an overhead projector is dipped into a solution comprising CF3(CF)7(CH2)2SiCl3. As a result, a molecular composed of CF3(CF2)7(CH2)2Si(O)3—is chemically bonded to the glass surface. A high charged state, a water-repelling property having a static contact angle of pure water on the thin film formed on the glass surface of 110 degrees and a volume electric resistivity in the range of 1×1011−1×1019&OHgr;·cm are provided.

An ink jet head (1), a substrate (13) receiving a liquid drop (2) discharged from the ink jet head (1), a device for irradiating or reflecting light from a nozzle hole or its vicinity of the ink jet head (1) toward the substrate (13), a position moving device (10) for controlling a relative position between the ink jet head (1) and the substrate (13), and a control device (9) for discharging a liquid from the ink jet head (1) are included. A light-receiving element (6) for recognizing a position of the ink jet head (1) is disposed behind the substrate (13), when seen from the ink jet head (1), the substrate (13) has a transparency at least to a degree that the irradiated light or the light reflected from the nozzle hole or its vicinity toward the substrate (13) enters the light-receiving element (6), and the light-receiving element (6) senses the irradiated light or the light reflected from the nozzle hole or its vicinity toward the substrate (13). Consequently, even if the distance between the ink jet head and the substrate is small, the relative position between the ink jet head and the substrate is adjusted accurately.

摘要:
A bearing device for a wheel prevents backlash in a circumferential direction and has excellent workability for connecting a hub wheel and an outer joint member of a constant velocity universal joint. The bearing device includes a recess-projection fitting structure in which the hub wheel and a shaft section, which is fitted in a hole of the hub wheel of the outer joint member of the constant velocity universal joint, are unitized together. In the recess-projection fitting structure, entire fitting regions among projections on the outer surface of the shaft section of the outer joint member and recesses, which fit on the projections, are brought into intimate contact with each other.
摘要:
A method for mounting an electronic circuit-constituting member on a substrate. The method includes preparing a substrate having a surface comprising a liquid-attracting first region and a liquid-repelling second region that surrounds the first region. The method also includes bringing water into contact with the surface of the substrate so as to dispose said water only on the said first region. The method further includes subjecting said substrate to a member-containing liquid that includes an organic solvent where an electronic circuit-constituting member are dispersed in the organic solvent to move said electronic circuit-constituting member to said water disposed on the said first region. The surface of the member is chemically modified with a silane coupling agent including a group with a C—Cl bond. Also, the method includes removing the water and the organic solvent from the surface of the substrate to mount said electronic circuit-constituting member on said substrate.
