Abstract
A large percentage of low-rank coal, which is abundant, has high moisture content and high oxygen content, and thus suffers from poor transportability. Further, when using such coal for heating, because of the loss of sensible heat of water and vaporization latent heat there is lowered thermal efficiency, and because of the high volatile matter content percentage, it is difficult to use such coal in existing coal combustion facilities. This combined system for manufacturing char/raw material gas from coal, and for generating electricity is provided with the following: a drying unit for drying low-rank coal that has high moisture content; a reformer for reforming the low-rank coal dried by the drying unit; a fluid bed furnace using the reformed coal obtained using the reformer as fuel; a producer gas supply pipe that supplies the combustion gas of the fluid bed furnace to the reformer as a thermal decomposition gasifier; and a catalyst reform device that reforms the producer gas and volatile components reformed by the reformer and obtained from the low-rank coal.

Abstract
By covering the inner circumferential surface of an outer cylinder with a vapor film, thermal conductivity is reduced and the phenomenon of sudden temperature increases in the cylinder wall of the outer cylinder can be prevented, thereby preventing heat damage to the outer cylinder. Additionally, burner burnout, caused by insufficient cooling resulting from irregularities in cooling efficiency at the burner tip, is also prevented. A tip, which is positioned inside a two-stage entrained-flow bed coal gasification furnace, has a double-walled cylindrical structure with an outer cylinder and an inner cylinder, and is configured so that cooling water to cool the tip is supplied via the inside of the inner cylinder and, after cooling the tip, is returned to the base end via the space formed between the outer cylinder and the inner cylinder, and is additionally configured so that the flow path surface area of the space formed between the outer cylinder and the inner cylinder is less than the flow path surface area formed inside the inner cylinder, thus configured so that a swirling flow along guides formed on the outer circumferential surface of the inner cylinder, and a roughly linear flow in the lengthwise direction of the outer cylinder and the inner cylinder, are imparted to the cooling water that is returning to the base end via the space formed between the outer cylinder and the inner cylinder.
To suppress the degradation of batteries and the reduction of operational efficiency, while implementing a cell balance operation with reliability. When a cell balance control performed by a cell balance circuit (3) is started, a system control apparatus (30) opens a switching device associated with an arm to be cell balance controlled. When the cell balance control is terminated and a difference between a voltage across the assembled battery of the arm that was cell balance controlled and the voltage across the assembled battery of each other arm is within a predetermined tolerance, the system control apparatus (30) closes the switching device that was previously opened.

METHOD FOR PREDICTING PULL-IN SITUATION OF CABLE IN CONDUIT
A method for predicting the pull-in situation of a cable in a conduit where pull-in tension and side pressure produced when a cable is pulled into a conduit can be predicted accurately. When the pull-in tension of a cable (10) being pulled into a conduit (30) is calculated, data on a radius of curvature acquired for every specified distance on the conduit (30) by previously measuring a radius of curvature at each part of the conduit is used, and the pull-in tension of the cable is calculated sequentially for every specified distance based on an actual radius of curvature and the known cable tension on the inlet side of a bend with a section at every specified distance on the conduit (30) assumed as a bend. Since the pull-in tension can be calculated with the impact of a bend of the conduit reflected appropriately over the entire conduit, an accurate prediction value of cable pull-in tension close to that at the time of an actual pull-in of the cable can be attained. Consequently, correct judgment can be made for cable pull-in, trouble can be prevented at the time of pulling in the cable, and processing results can be obtained quickly by simplifying calculation processing.

A conduit testing body having a structure in which spherical portions (11, 12, 13) are connected by bar-like portions (21, 22). Although the spherical portions (11, 12, 13) has a size close to the inner diameter of a conduit (50), they are less likely to interfere with the inner peripheral surface of the bent conduit (50) because sections between spherical portions are the bar-like portions (21, 22) that are thin. As a consequence, even if the outer diameter of the spherical portions (11, 12, 13), which are set along the inner surface of the conduit (50), is extremely close to the inner diameter of the conduit (50), the entire testing body (1) can be moved along a curvature of the conduit (50) which curvature is within an appropriate range. When the testing body (1) is pulled into the conduit (50), if the diameter of the spherical portions (11, 12, 13) is closer to the inner diameter of the conduit (50), the testing body (1) does not pass a portion where there is a step and stays more easily at the step. In a test for passing a wire to the conduit (50), curvature radius measurement and step detection at each point of the conduit (50) can be accurately performed, abnormal conditions can be reliably detected by simple work, and a trouble in actual cable drawing can be prevented.
