Abstract: A case has a front surface facing an image sensing area, a concave formed on the front surface, and an opening on the bottom of the concave. The case accommodates an area image sensor to image-sense the image sensing area through the opening, and an illumination device to illuminate the entire image sensing area. There are provided a photoelectric converting unit converting an output of the area image sensor into an electric image signal, and an output unit outputs an image signal converted by the photoelectric converting unit to an image processing device. The case also accommodates a lens to form an image of the image sensing area on the area image sensor with a depth of field so as to the image processing device obtain a resolution to enable analysis of a code symbol included in the image signal. A lens side limit position of the depth of field corresponds with the position of the front surface of the case.

Abstract: A method of making metallic iron in which a compact, containing iron oxide such as iron ore or the like and a carbonaceous reductant such as coal or the like, is used as material, and the iron oxide is reduced through the application of heat, thereby making metallic iron. In the course of this reduction, a shell composed of metallic iron is generated and grown on the surface of the compact, and slag aggregates inside the shell. This reduction continues until substantially no iron oxide is present within the metallic iron shell. Subsequently, heating is further performed to melt the metallic iron and slag. Molten metallic iron and molten slag are separated one from the other, thereby obtaining metallic iron with a relatively high metallization ratio.

Abstract: A nonvolatile semiconductor memory recovers variation in the threshold of a memory cell due to disturbance related to a word line. The nonvolatile memory continuously performs many writing operations without carrying out single-sector erasing after each writing operation, performing the additional writing operations quicker than the usual writing operation, and lightening the burden imposed on software for use in additional writing. The data stored in a designated sector is read out before being saved in a register, and the selected sector is subjected to single-sector erasing when a predetermined command is given. Then write expected value data is formed from the saved data and data to be additionally written, completing the writing operation.

Abstract: A method for producing an iron oxide pellet including the steps of adding water to a raw material mixture comprising iron oxide which serves as a primary component, a carbonaceous material in an amount sufficient for reducing the iron oxide, an organic binder in an amount sufficient for binding the iron oxide and the carbonaceous material, and an inorganic coagulant in an amount of not less than 0.05 mass % and less than 1 mass %; pelletizing the resultant mixture to thereby obtain a green pellet; and drying the green pellet until the moisture content is reduced to equal to or less than 1.0 mass %. The thus-produced iron oxide pellet is charged in a reducing furnace for reduction to thereby obtain a reduced iron pellet.

Abstract: When obtaining an ID code from a user who holds out an arm to a corresponding merchandise in a noncontact manner, respective information terminal devices accept a registration input of the corresponding merchandise. When accepting the registration input of the corresponding merchandise, registration merchandise information including obtained user identification information and merchandise identification information for identifying the merchandise corresponding to the information terminal device is transmitted to a server device. The server device stores and manages merchandise sales information for the respective ID codes from the registration merchandise information received from the respective information terminal devices. When the ID code is input from a settlement device, the merchandise sales information corresponding to the ID code is transmitted to the settlement device. The settlement device performs the settlement processing based on the merchandise sales information received from the server device.

Abstract: An article code reading device optically reads a code symbol on to an article and specifies the article, and decodes and outputs an article code. An image pickup image part picks up an image of an area of an article, the code symbol of which is read by the article code reading device, and outputs pickup image data. An article registration is executed by searching an article data file for a corresponding price for the article, and an extraction process extracts an exterior characteristic of an article from a the pickup image data outputted by the pickup image part. A consistency is determined between a first data obtained based on the extraction process and a second data obtained based on an output from the article code reading device, and an alarm is generated when it there is not a consistency between the first data and the second data.

Abstract: In an electric vacuum cleaner including a communicating tube forming an air trunk which communicates to a suction opening which suctions dust and a vacuum cleaner main body having a communicating tube attachment member attaching the communicating tube, a strain gauge is attached to a floor surface side of the communicating tube attachment member. This strain gauge is connected to one side of a resistor bridge circuit. Tension acts on the strain gauge due to an operation of the communicating tube during the cleaning so that an output is generated at the resistor bridge circuit. After being amplified, this output is differentiated in a condenser. This differentiated voltage signal is compared to a threshold level voltage in a comparator. A running motor is driven only in a period that the voltage signal exceeds the threshold level voltage.
