Abstract: An object of the present invention is to provide a flat-winding type secondary battery having a simple structure and thus capable of being manufactured in a simplified manufacturing process. A flat-winding type secondary battery according to the present invention is a flat-winding type secondary battery having a flat-shaped winding group obtained by winding positive and negative electrodes with separators interposed therebetween. The winding group has a shaft core having a configuration in which leading end portions of a sheet member at both sides in a winding direction are folded in an a mutually approaching direction and disposed at positions separated from each other, the sheet member having a higher bending rigidity than that of any of the positive and negative electrodes and separators.

Abstract: In a designing assisting apparatus 901, a memory section 902 stores trouble records of a design target, a dictionary section 903 stores related records, an input accepting section 904 accepts the input of a definition attribute name, a control attribute name or a stress attribute name, a search section 905 searches for that trouble record which includes the definition attribute name, etc., searches for that related record which includes the trouble mode name included in the searched trouble record, as a cause name, searches for that trouble record which includes the definition attribute name, control attribute name, stress attribute name, strength name or trouble mode name included as a result name in the searched related record, and repeats them until no new trouble record is searched, and a display section 906 displays the searched trouble record, and displays an arrow associated with the searched related record between the trouble records.

Abstract: An input reception unit of a design support apparatus receives input of a definition attribute name of a product to be designed. A definition attribute obtaining unit, control attribute obtaining unit and stress obtaining unit obtain parameter names usable for calculating a strength value and stress value, based on the definition attribute name. The input reception unit further receives input of parameter values of the parameter names. A strength calculation unit calculates a strength value of the product to be designed in accordance with a predetermined calculation procedure using the parameter value. The stress calculation unit calculates a value of stress applied to the product to be designed in accordance with a predetermined calculation procedure using the parameter value. The comparison report unit compares the strength value and the stress value, and reports report information associated with those values in a case where the comparison result satisfies a predetermined condition.

Abstract: A planing type boat having a water ballast chamber provided at the bottom of the boat includes a partition wall provided in the water ballast chamber to divide the chamber into front and rear compartments and formed with an opening for communicating these compartments with each other. In the initial stage of planing, the water in the rear compartment is fastly discharged due to a combined action of inertia, gravity and aspiration induced by the outside flow whereas the water in the front compartment which is restricted in its rearward flow by the partition wall structure is discharged relatively slowly as compared with the water in the rear compartment. The weight of the water therefore substantially acts on the front compartment in the initial stage of planing thereby effectively preventing the bow of the boat from being excessively lifted with the result that the time required for entering a complete planing is minimized.
