In a color reading apparatus for successively reading respective red, green, and blue colors in each line while a document is continuously conveyed to a plurality of line sensor units arranged in a zigzag manner, the line sensor units are arranged with a distance equal to or shorter than a unit of line to prevent a color shift. When read data of the plurality of line sensor units in a conveying direction are to be combined, image data shifted by the number of lines corresponding to distances between the line sensor units in the conveying direction are set as first combination candidates. A color code and a line code are added to each of the data. Image data having the same color code and the same line code are combined. According to the image reading apparatus structured as described above, it is possible to obtain data capable of reproducing read data for each color on the same line without errors.

A runner-less molding device for thermosetting resins and rubbers, characterized by a movable runner bush (15), through which an uncured or unvulcanized fluid material kept at a low temperature supplied from a pouring nozzle (31) can flow, is slidably arranged in a temperature controlling bush (13) communicating with a gate (4) of a cavity (1); an insulation space (A) is formed by moving the movable runner bush (15) apart from the gate (4) during heating; a valve pin (18) is movably inserted into said movable runner bush (15); and the valve pin (18) is arranged so as to open and close the gate (4) in accordance with a pouring operation of the fluid material. A runner part of the movable runner bush containing molding material is constituted so as to move forward/backward relative to the cavity for preventing heat from conducting from the cavity, which is kept at a molding temperature, to the runner positioned apart from the gate for a long time, so that material loss generated in a sprue runner is reduced to almost null in order to reduce fabricating costs after molding and amount of wastes generated during after treatments. Thus, the improved molding device for the thermosetting resin and the rubber is obtained, and burdens on the global environment are alleviated.

A semiconductor device is capable of being applied with both a positive and a negative voltage to its control gate, and writing to its memory requires a low voltage. A control gate is formed on a memory unit region of a field oxide film, and an inter-layer silicon oxide film is formed on its surface. A gate oxide film for a non-volatile memory is formed on a P substrate between N type diffusion layers. The floating gate is formed on the inter-layer silicon oxide film, the field oxide film, and the gate oxide film for the non-volatile memory. Since a large coupling ratio between the control gate and the floating gate is available on the field oxide film, memory rewriting requires only a low voltage. Further, since the control gate is formed by a poly silicon film, both a positive voltage and a negative voltage can be applied to the control gate.

A visual axis entry transmission apparatus and method enables a physically handicapped person who can not depress a foot button to easily transmit the selection of a character to be input. 50 characters are displayed, via a display controller, on the liquid crystal device of a head-mounted display unit and on an external monitor. The visual axis position of a user is detected by a visual axis detection circuit, and a character at the visual axis position is obtained based on the detected visual axis position data. Selection character data for the past 100 selections are then updated. When the condition for the entry of a character is satisfied by this new character selection, the character is added to an input character string, and the newly input character is pronounced to notify the user that the character entry has been completed. The visual axis position data are employed to determine the detection result, such as a condition where the visual axis detection was successful, the visual axis detection failed, the eyes were blinking, or the same option was selected. In accordance with the result of the determination, the color of the selection frame for a character is changed to provide the user detection result information that represents the detection result condition, thereby confirming the results of a detection of a line of sight and avoiding having to unnecessarily repeat an operation.

A cleaning unit for cleaning a substrate is disclosed, that comprises a holding mechanism for rotatably and horizontally holding the substrate, a first traveling means for holding both sides of a cleaning mechanism having at least one cleaning member and for moving the cleaning mechanism in such a manner that the first traveling means is kept in parallel with the substrate held by the holding mechanism, and a second traveling means for holding both sides of a processing solution supplying mechanism having supplying mechanisms for supplying different types of processing solution and for moving the cleaning mechanism in such a manner that the second traveling means is kept in parallel with the substrate held by the holding mechanism. Thus, the strength of the cleaning unit according to the present invention is higher than the strength of a conventional cleaning unit that holds an arm on one side thereof. In addition, a process of a cleaning mechanism and a process of a supplying mechanism can be equally performed on the entire surface of the substrate.

A photographing device has a range sensor including a plurality of range sensing elements, and a photometric sensor including a plurality of photometric elements. The positions of the photometric elements on the photometric sensor correspond to the positions of the range finding elements on the range sensor. Further, the area of each photometric element is larger than the area of the corresponding range finding element. Thus, proper exposure control may be affected for a selected range finding element.
