摘要:
A pressing unit includes a pressure roller that slides on the folded side while rotating, an elastic biasing unit that presses the pressure roller in a thickness direction of the stack of sheets, and a driving unit that slides the pressure roller in a direction substantially perpendicular to a conveying direction of the stack of sheets. A lifting unit, when the pressure roller slides to a first position, temporarily lifts up the pressure roller, and when lifted-up pressure roller slides to a second position, lifts the lifted-up pressure roller down onto the folded side.

Provided are an ink jet ink set, an ink jet recording method, and an ink jet recording apparatus each of which can reduce the graininess of an image to be recorded and improve the water fastness of the image even in a recording medium such as plain paper. The ink jet ink set has a first ink and a second ink independently, and is used so that the first and second inks overlap each other at least partly upon application of the inks to a recording medium. The first ink contains at least a pigment and a silicone oil. The second ink contains at least a pigment and a graft polymer that includes at least a nonionic unit represented by the general formula (I) and a unit having a polysiloxane structure.

摘要:
This invention introduces, as one aspect, an apparatus for creating three-dimensional object model, comprising photographing means for photographing an object to be modeled for obtaining images to be used for creating the three-dimensional object model, setting means for longitudinally and latitudinally setting a relative position between the object and said photographing means, said setting means being capable of setting the object and said photographing means a plurality of different relative longitudinal and latitudinal positions, and control means for controlling said photographing means and said setting means so that a number of photographs taken from different relative longitudinal positions at a first relative latitudinal position is larger than that taken from different relative longitudinal positions at a second relative latitudinal position, the first relative latitudinal position being closer to a lateral position than the second relative latitudinal position. Accordingly, it becomes possible to minimize the number of photographs for obtaining necessary images to effectively keep a high quality three-dimensional object model, the number of user's manual operations is reduced, and the total photographing time for creating a three-dimensional object model is significantly decreased.
摘要:
In a sheet creaser, a sheet set is pushed between a pair of folding rollers to fold the sheet set. Then, a re-pressing roller re-presses the sheet set, which has been folded by the folding rollers, by rolling along the crease. Pressure applied on the sheet set by the folding rollers is released when the re-pressing roller re-presses the sheet set.

This invention relates to a silicone resin composition which exhibits high heat resistance, high transparency and high dimensional stability and thus can be suitably used for optical applications such as a lens, an optical disc, an optical fiber, a substrate for a plat panel display, a window material for an automobile, and the like. A silicone resin composition, which comprises a silicone resin comprising, as a primary component, a polyorganosilsesquioxane being represented by the formula: [RSiO3/2]n, wherein R represents an organic functional group having a (meth)acryloyl group, and n is 8, 10 or 12, and having a cage type structure in its structural unit, and an unsaturated compound having, in its molecule, at least one unsaturated group represented by —R3—CR4═CH2 or —CR4═CH2, wherein R3 represents an alkylene group, an alkylidene group or a —OCO— group and R4 represents a hydrogen atom or an alkyl group, and being capable of radically copolymerizing with the above silicone resin, in a weight proportion of 1:99 to 99:1.
摘要:
A passivation film including a nitride-reformed layer that excludes chromium nitride (CrN) is formed on a surface of an austenitic stainless steel. The passivation film composed of chromium oxide functions as protection film against lead-free solder. As a result, the surface of stainless steel is hard to be corroded even when it contacts with the lead-free solder in its melted solder, thereby improving its corrosion resistance and its wear resistance substantially. In a case of SUS316 stainless steel, on an outermost surface of which the passivation film is formed, a period of lapsed time until corrosion of the stainless steel starts extends to about 500 hours as line Le shown in FIG. 4, and its corrosion depth indicates shallower one (20 through 25 μm) as compared with the conventional one, thereby expecting that its durable year can be improved to an extent similar to that using a lead-filled solder, in order to obtain a stainless steel with enhanced corrosion resistance.
