Abstract: The method of controlling rechargeable battery power is a method that includes limiting the amount of usable power during rechargeable battery charging and discharging, determining a rechargeable battery current-voltage characteristic function based on rechargeable battery charging and discharging current flow and voltage, finding a limiting discharging current Imax and/or a limiting charging current Imin from a prescribed minimum voltage Vmin to prevent over-discharging and/or a prescribed maximum voltage Vmax to prevent over-charging and their intersection with the current-voltage characteristic function, and controlling current such that discharging current greater than or equal to Imax and/or charging current less than or equal to Imin does not flow through the rechargeable batteries. In this fashion, the amount of usable power can be limited considering factors such as the memory effect, and the rechargeable battery can be used to its maximum capability within the range of safe operation.

Abstract: A method of detecting a state-of-charge of a battery detects a current of a battery and a voltage of the battery, calculating a state-of-charge of the battery as a first state-of-charge based on an integration of the current of the battery thus detected, while calculating the state-of-charge of the battery as a second state-of-charge based on the voltage of the battery and calculating a synthetic state-of-charge obtained by taking a weighted mean of the first state-of-charge and the second state-of-charge as the state-of-charge of the battery, and weighting the weighted mean in order to increase weighting of the second state-of-charge in a region in which a capacity of the battery is increased and a region in which the capacity of the battery is reduced and to increase weighting of the first state-of-charge in other regions.

Abstract: Related to a blast furnace coke and a production method thereof. A coke having high reactivity and high strength in which coke strength, reactivity with CO2 and a pore size distribution are each at a desired level can be produced at a low cost by using a coal blend composed of a small number of brands comprising a large quantity of caking coal having medium rank and low fluidity.

Abstract: The invention relates to a glass plate having a molding formed on a peripheral edge thereof. The present invention provides an extrusion die having first and second void spaces formed therein. The first void space is provided for supplying an adhesive to the peripheral edge, and the second void space is provided for supplying a molding material to the peripheral edge. The first and second void spaces are specifically arranged relative to each other. With this, while the glass plate is moved relative to the extrusion die, the molding is extruded on the peripheral edge simultaneously with the formation of the adhesive layer on the peripheral edge. Thus, the formations of the molding and the adhesive layer are conducted in one production process. With this, the production efficiency is much improved.

Abstract: The invention relates to the control of a tunnel furnace partitioned into a plurality of zones for heat treatment of, e.g., ceramic or glass workpieces. As usual the temperatures of the respective zones are controllable individually. Furthermore, in each of selected zones the temperature of that zone is varied from a first level to a second level during the stay of each workpiece in that zone and returned to the first level in a predetermined time after letting the workpiece out of that zone, and the length of stay of each workpiece in that zone is controlled such that another workpiece can be introduced into that zone while the preceding workpiece stays in the next zone and such that a number of workpieces can be heat treated in succession under the same time-temperature conditions.

Abstract: The invention relates to a method of fitting a plate member with at least one supportive or protective member of a synthetic resin by injection molding of the resin with insertion of, for each resin member, a predetermined marginal region of the plate member in the mold cavity. For example, a vehicle window glass is fitted with two holders to be coupled with a window regulator mechanism. To enhance strength of adhesion of the molded resin member(s) to the plate without making any mechanical or thermal treatment of the plate, the marginal region of the plate is closely covered with at least one sheet of plastic film, which has a thickness of 5 to 250 .mu.m and becomes a melt adhesive to both the plate and the molded resin at a temperature in the range from 50.degree. to 150.degree. C., prior to insertion of the marginal region of the plate into the mold cavity. For example, the plastic film is of an ethylene base copolymer.
