Abstract:
This invention solves the problem of color misalignment upon reading a color image. An image reading apparatus according to this invention reads an image by scanning a scanning unit which mounts a reading sensor which reads light beams which are emitted by three light sources, which emit light beams of three primary colors, and reflected by an original document. The image reading apparatus conveys the original document by ⅓ of the reading width of the reading sensor in the conveyance direction of the original document every time the image is read. The image is read by switching between the three light sources so that each pixel of the image is read with the light beams from them.
Abstract:
A printing system that adopts an SBC system in which a load at a server is alleviated when executing printing to enable printing to be performed smoothly. In the printing system, a client terminal, a server, and an image forming apparatus are connected to each other through a network. The client terminal specifies data among stored data in the server and sends a print execution request to the server. The server receives the print execution request, creates print-related information relating to the specified data, and sends it to the client terminal. The client terminal judges whether or not print data generation processing with respect to the specified data is possible at the client terminal based on the print-related information, and send the judgment result to the server. The server allocates the print data generation processing to either the server or the client terminal based on the judgment result.
Abstract:
In a conventional switch circuit capable of bidirectional conductivity, there is the problem that latch-up occurs in a parasitic thyristor included in a transistor having a switching function. Therefore it is an object of the present invention to provide a switch circuit capable of bidirectional conductivity while suppressing the occurrence of latch-up due to a parasitic thyristor. The present invention provides a switch circuit that includes diodes connected in parallel with each of a MOS transistor having the switching function and parasitic diodes present at the source and the drain of the MOS transistor.

A memory cell structure and control of the memory operation are simplified, and the cost of production is decreased, by way of a semiconductor nonvolatile memory having a transistor including a gate electrode provided on a p-type semiconductor substrate via a gate insulating film, and a source region and a drain region, which are a pair of n-type impurity diffusion regions in the surface layer region of the semiconductor substrate at positions sandwiching the gate electrodes therebetween. A first resistance-varying portion and a second resistance-varying portion are sandwiched by the source region, drain region and channel-forming region. The n-type impurity concentration in the resistance-varying portions is lower than in the source and drain regions.

Abstract:
To divide into individual devices efficiently in dicing a wafer without causing quality of the devices to lower, a wafer processing method includes steps of coating a rear surface of the wafer with a resist film, exposing and sensitizing portions of the resist film other than regions corresponding to the streets; and supplying a silylation agent onto a surface of the resist film and silylating the resist film in a sensitized region. In an etching unit, an oxygen- or chlorine-containing gas is plasmatized and supplied to a rear surface of the wafer coated with a silylated resist film, and the resist film in an unsilylated regions corresponding to the streets is ashed and removed. A stable fluoride gas is plasmatized and supplied to the rear surface of the wafer, and the resist film in the regions corresponding to the streets is etch-removed to divide the wafer W into individual devices.
Abstract:
In one example, a nonvolatile semiconductor memory includes a transistor, one or two resistance-change portions, and one or two charge accumulation portions. The transistor has a control electrode, first main electrode region, and second main electrode region. If two resistance-change portions are provided, one of them is provided in the surface region of a substrate between the first main electrode region and a channel formation region opposing the control electrode, and the other is provided in the surface region of the substrate between the second main electrode region and the channel formation region. Each resistance-change portion is of a second conductivity type having impurity concentration lower than that of the first and second main electrode regions. The charge accumulation portions are provided on the associated resistance-change portions. Each charge accumulation portion has an insulating layer, and is capable of accumulating charge. It should be assumed that information is recorded in such nonvolatile semiconductor memory in which information has been erased in advance by charge accumulation. When the first conductivity type is the p type and the second conductivity type is the n type, an information recording method includes applying a high positive voltage to one of the main electrode regions, setting the other main electrode region to ground voltage, and applying a positive voltage to the control electrode so as to cause weak inversion of the channel formation region.

A couple of bits of data can be stored in the memory cell, the stored data being controlled according to resistance values of first and second variable resistance regions. One of the plurality of memory cells shares its first diffusion layer with an adjacent memory cell and shares its second diffusion layer with another adjacent memory cell.

The second diffusion layers of the plurality of memory cells are coupled to each other with a second conductive line extending in the first direction. The gate electrodes of the plurality of memory cells are coupled to each other with a third conductive line extending in a second direction, which is orthogonal to the first direction.
