摘要:
A diorganopolysiloxane terminated only at one of the molecular chain ends with a (meth)acryloxyalkyl group bonded to the terminal silicon atom is prepared, instead of the prior art method in which a diorganopolysiloxane obtained by the anionic ring-opening living polymerization reaction of, for example, hexamethyl cyclotrisiloxane by using a lithium catalyst is subjected to a desalinating condensation reaction with a (meth)acryloxyalkyl dimethyl chlorosilane, by a novel method in which the diorganopolysiloxane obtained by the anionic ring-opening living polymerization reaction of, for example, hexamethyl cyclotrisiloxane is hydrolyzed and the thus obtained monofunctionally silanol-terminated diorganopolysiloxane is reacted with a (meth)acryloxyalkyl dimethyl dialkylamino silane to effect a deamination reaction. This method is advantageous in that the relatively narrow molecular weight distribution of the diorganopolysiloxane obtained by the anionic living polymerization is not affected and retained as such in the deamination reaction while not in the prior art method.

An image forming apparatus includes a controller that provides control in which, if image formation processing by a single unit is executed first since a density adjustment condition for adjusting a density of an image is satisfied, a density adjustment value is changed by a predetermined basic change amount, and a first image is formed in a corresponding image formed region with a density that is adjusted in accordance with the changed density adjustment value, and control in which, if a single image other than the first image is formed in the corresponding image formed region, the current density adjustment value is changed by a predetermined fine change amount that is smaller than the basic change amount, and the single image is formed in the corresponding image formed region with a density that is adjusted in accordance with the changed density adjustment value.

An image-forming apparatus in which a replacement part is loaded includes a discrimination unit that discriminates whether or not identification data registered in the loaded replacement part correspond to either inherent data or group data registered in the image-forming apparatus; a determination unit that, when no correspondence is found in the discrimination unit, determines in accordance with a registration condition whether or not a value of the identification data is registered as the group data; and an establishment unit that establishes approval or disapproval of use of the loaded replacement part on the basis of a result of discrimination performed in the discrimination unit or determination performed in the determination unit.

An inputting device which includes an image input section for inputting an image of a containing areas in which information to be inputted is filled in and patterns representing at least reference positions to define the positions of corresponding areas and size information of corresponding areas; a memory section for storing the image of the input by the image input section; a pattern recognizing section for detecting the reference positions from the patterns in the image which is stored in the memory section and recognizing size information of the areas; an area specifying section for specifying the positions of the areas from the reference positions detected by the pattern recognizing section and the size information of the areas; and an area inputting section for inputting images in the areas defined by the area specifying section.
摘要:
A semiconductor device includes: a SOI substrate having a SOI layer, a buried oxide layer and a support substrate; multiple first separation trenches on the SOI layer; multiple MOS transistors, each of which is surrounded with one first separation trench; a second separation trench on the SOI layer including n-ply field trenches; and multiple field regions such that a k-th field region is surrounded with a k-th field trench. One MOS transistor is disposed in each field region. The MOS transistors are connected in series. The first MOS transistor has a gate terminal as an input terminal. The n-th MOS transistor is connected to the power source potential through an output resistor. The n-th field region has an electric potential, which is fixed to the power source potential.
