摘要:
It is an object to provide a conductive organic thin film having organic molecules that include at one end a terminal bonding group that is covalently bonded to a substrate surface, a conjugate bonding group that is located at any portion of the organic molecules and that is polymerized with other molecules, and a polar functional group that does not include active hydrogen and that is located at any portion between the terminal bonding group and the conjugate bonding group, wherein the organic molecules are oriented and their conjugate bonding groups are polymerized, forming a conduction network. The conductivity (ρ) of the conductive organic thin film at room temperature (25° C.) is at least 5.5×105 S/cm, and preferably at least 1×107 S/cm, without dopants, having significantly higher conductivity than metals such as gold and silver. In particular, a film of polypyrrole or polythienylene conjugate bonds that is polymerized through polymerization through electrolytic oxidation has high conductivity.

摘要:
A semiconductor device provided with a thin-film transistor comprising a polycrystalline semiconductor thin film (2) formed on an insulating substrate (100). The semiconductor device comprises a channel region (80), a source region (91), and a drain region (92), each disposed on both sides of the channel region (80) in the semiconductor thin film (100). The channel region (90) comprises both a first conductive impurity and a second conductive impurity, the conductive type of the second conductive impurity being opposite the conductive type of the first conductive impurity, and is structured by layering a first layer in which the first conductive impurity and the second conductive impurity are canceled and a second layer in which either of the first conductive impurity or the second conductive impurity is dominant, wherein a gate electrode (4) is formed so as to face the first layer (2a) via an insulating film (3). The source region (91) and the drain region (92) have a conductive type that is opposite the conductive type that is dominant in the second layer (2b). This structure reduces OFF-current and makes it easy to control threshold voltage.

A power supply system includes a plurality of electric products; a power generation apparatus capable of varying an amount of power generation; and a power control apparatus for controlling power supply from the power generation apparatus to the plurality of electric products. Each of the plurality of electric products is structured to be capable of outputting a first power request signal for requesting a desired amount of power. The power control apparatus receives the plurality of first power request signals respectively from the plurality of electric products, generates a second power request signal for requesting an amount of power which is determined in accordance with a total amount of power requested by the plurality of first power request signals, and outputs the second power request signal to the power generation apparatus. The power generation apparatus increases or decreases the amount of power generation so as to match the amount of power generation with a target amount of power generation which is determined in accordance with the second power request signal.

A manuscript display apparatus includes a bow-shaped main body having a light emitting body housed therein translucent diffusion plate arranged on top of the main body to diffuse light emitted from the light emitting body, a support portion rotatably supported with respect to the main body, and a half mirror supported at the tip end of the support portion. When the manuscript display apparatus is to be used, a manuscript sheet is placed on top of the diffusion plate in such a way that its surface on which a manuscript is written faces down to th diffusion plate. The light emitted from the light emitting body is diffused by the diffusion plate and uniformly illuminate the manuscript sheet from the underside thereof. The light that passes through the manuscript sheet is reflected off the half mirror and therefor the manuscript is displayed as a virtual image. Because the virtual image is reversed at the half mirror, the virtual image displays the manuscript of the manuscript sheet in its original form.

摘要:
A microscope comprises a cantilever having a distal end equipped with an electrically conductive probe allowing current to flow and having a fine tip whose voltage is controllable, a position control mechanism for controlling position of a sample with respect to a base end of the cantilever, a small displacement measuring mechanism for measuring a deflection amount of the cantilever, and a deflection control mechanism for controlling deflection of the cantilever so as to adjust a distance between the fine tip of the probe and the sample. A method for measuring surfaces using this novel microscope comprises steps of: maintaining deflection of the cantilever at a constant value by using the small displacement measuring mechanism and the deflection control mechanism; applying a constant voltage between the electrically conductive probe and the sample; scanning the sample along surface of the sample with the probe, while a tunneling current is maintained at a constant value by using the position control mechanism; and measuring a control amount of the position control mechanism in a direction vertical to the sample and a control amount of the deflection control mechanism.

Method for producing an extrusion die and resulting die for making a honeycomb structure provided with axially extending separate passages. Feed passages and interconnected pooling slots are formed in a metallic die body respectively from opposed end surfaces so as to be communicated with each other. A metallic plate is bonded as by brazing to the end surface provided with the interconnected pooling slots and formed in that plate to communicate with the pooling slots are narrower interconnected extrusion slots having the same shape and size as those of walls of the desired honeycomb structure. Before securing the metal plate to the end surface, holes are made either in the plate or in the end surface, or both, to increase the bonding contact area therebetween.
