Abstract: An image reading device includes (i) light guides extending in a main scanning direction and configured to emit light from a light source toward a reading target moving relatively in a sub-scanning direction, the light from the light source being projected into end surfaces of the light guides in the main scanning direction, (ii) an optical filter arranged between the light source and the end surfaces of the light guides and configured to block or attenuate light having a specific wavelength from the light from the light source, (iii) a lens body to focus reflected light reflected by the reading target onto a light receiver to convert the reflected light into an electrical signal, and (iv) a lens holder. The lens holder includes a first positioner for positioning the light guides and a second positioner for positioning the optical filter.

Abstract: By inhibiting generation of particles, a carbon material and a method of manufacturing the carbon material are provided that can be used in the field of semiconductor manufacturing or the like, in which low dust emission is considered important. A carbon material having a chromium carbide layer formed on a surface of a carbon substrate. The chromium carbide layer is composed of Cr3C2. The carbon material can be manufactured through a first step of forming a chromium carbide layer containing a chromium carbide other than Cr3C2 on a surface of a carbon substrate, and a second step of heat-treating the carbon substrate under a reducing atmosphere to convert the chromium carbide other than Cr3C2 into Cr3C2.

Abstract: A carbon material, a jig, and a method of manufacturing the carbon material are provided that can prevent dust emission and also improve the temperature resistance under a nitrogen atmosphere. In a carbon material having a carbon substrate and a metal carbide layer formed on a surface of the carbon substrate, the metal carbide layer includes molybdenum carbide and/or iron carbide. The carbon substrate embedded in a surface modifying agent containing a pyrolytic hydrogen halide generating agent and molybdenum particles and/or iron particles is heat-treated together with a carbon member other than the carbon substrate.

Abstract: A carbon material and a method of manufacturing the same are provided that make it possible to form a layer of a metal that is highly reactive with carbon, such as tungsten, on a carbon substrate while at the same time inhibiting an increase in manufacturing cost and a degradation of processing accuracy. The carbon material has a carbon substrate 2, a first layer 12, and a second layer 13. The first layer contains a carbide of a transition metal. The second layer contains a second metal and/or a carbide of the second metal and a carbide of the transition metal, the second metal being at least one metal selected from the group of metals consisting of Group 4 elements, Group 5 elements, and Group 6 elements. The first and second layers are formed on a surface of the carbon substrate in that order.

Abstract: When treated with a halogen gas, a carbon material can inhibit emission of an impurity after the treatment. A method of manufacturing the carbon material is also provided. A carbon material is subjected to an annealing process under a reduced pressure of from 1 to 10000 Pa in a H2 gas atmosphere at 500° C. to 1200° C. The duration of the annealing process is from 1 minute to 20 hours. This makes it possible to control the concentration of the halogen emitted, such as chlorine, to 5 ppb or less.

Abstract: A method of manufacturing a carbon material that can prevent formation of unevenness of a coating film and degradation in adhesivity of the coating film, by inhibiting a carbon substrate from forming a portion in which a metal carbide layer is not formed. The method is characterized by including a first step of causing metal powder to adhere to a carbon substrate by coating the carbon substrate with a slurry containing the metal powder and polyvinyl alcohol as a binder, and a second step of heat-treating the carbon substrate to which the metal powder has adhered in a vessel containing an atmosphere of hydrogen chloride gas.

Abstract: This invention is a multi-coupled power conversion system including power converters 114 and 124 connected in parallel through reactors 105, with each power converter converting a d.c. voltage into an a.c. voltage by means of automatic turn-off switching devices which turn on and off in response to on/off commands. The system includes a spatial voltage vector calculator 101 which, in order to provide the on/off commands for the parallel-connected power converters 114 and 124, selects multiple spatial voltage vectors in accordance with the amplitude Vc and phase .theta. of the command of the a.c. voltage to be produced by the power converters 114 and 124 and calculates vector output times, a vector permutation device 102 which determines two sets of the order of generation of the selected spatial voltage vectors, and PWM generators 113 and 123 which generate the on/off commands in response to the output of said vector permutation device 102.
