Abstract: A charging/discharging device performs charging and discharging on a plurality of secondary cells concurrently in parallel, without adopting a power source having an extremely high current supply capacity. A plurality of switching units controlled by a switching control unit are interposed respectively between the secondary cells and each of a plurality of charging power lines and discharging power lines. A power unit applies voltages having mutually-different voltage values and the switching control unit controls switching so that the respective secondary cells are connected cyclically in predetermined order to the charging and discharge power lines.

Abstract: Handling to a subsequent step of cell examining/testing can be performed as keeping the same shape owing to that a sheet-shaped cell is alternately folded and an electrode terminal is inserted to a gap of the folded sheet-shaped cell, and test space can be saved by lessening a size of a testing device for a cell. A testing device for a sheet-shaped cell and a testing method for a sheet-shaped cell according to the present invention includes a folding unit that folds a sheet-shaped cell having electrode layers on both faces while alternately changing a folding direction, and a testing unit that performs a predetermined test as supplying power to electrode terminals in a state that the electrode terminals are inserted respectively to folded portions of the sheet-shaped cell.

Abstract: Provided is a secondary battery being superior to a conventional secondary battery with respect to volume (energy density) and manufacturing (manufacturing workload). The present invention provides a secondary battery including a sheet-shaped first-electrode-functioning base material having a function as a first electrode and a function as a base material, a front-side storage layer formed on a front side of the first-electrode-functioning base material, a front-side second electrode layer layered on the front-side storage layer, a rear-side storage layer formed on a rear side of the first-electrode-functioning base material, and a rear-side second electrode layer layered on the rear-side storage layer.

Abstract: A method for manufacturing a probe card is provided wherein probes are held in a holding plate such that the respective probes correspond to through holes with their connecting end portions projected from one surface of the holding plate. A plate-like member including openings having larger diameters than diameters of the through holes and housing the connecting end portions in the openings is arranged by making one surface of the plate-like member abut the one surface of the holding plate. After supplying solder cream in the respective openings from the other surface of the plate-like member, a connection base plate and the holding plate are relatively fixed so that the solder cream, burying the connecting end portions of the respective probes held in the holding plate with the plate-like member removed, may abut the respective corresponding connection pads, and the solder cream is heated to melt the solder cream.

Abstract: A packaging member includes a cushioning member that holds a holding part of a to-be-packaged member different from a predetermined part of the to-be-packaged member without coming into contact with the predetermined part of the to-be-packaged member. The cushioning member cushions a shock transmitting to the to-be-packaged member, and the packaging member packages the to-be-packaged member via the cushioning member.

Abstract: One plate-like member and the other plate-like member to be aligned with each other are provided with guide holes and guide portions to be received in the guide holes, respectively. The plate-like members are aligned appropriately, and in a state in which this alignment is held, the guide portions are formed on land portions provided on the other plate-like member so as to be aligned with the guide holes. Accordingly, regardless of presence/absence or size of a process error in the guide holes, the guide portions appropriate to the respective guide holes can be formed. Consequently, by aligning the guide portions with the guide holes, the plate-like members can be aligned appropriately without relative fine adjustment between the members.

Abstract: To provide a charging/discharging device capable of performing charging and discharging on a plurality of secondary cells concurrently in parallel without adopting a power source having an extremely high current supply capacity.

Abstract: Provided is a secondary battery adopting an all-solid-state secondary cell structure with a storage layer sandwiched between a positive electrode layer and a negative electrode layer and which is superior to a conventional secondary battery with respect to at least one of volume, manufacturing, and positioning. The present invention provides a secondary battery including a single-layer secondary cell having a folded structure that a sheet-shaped single-layer secondary cell with a storage layer sandwiched between a positive electrode layer and a negative electrode layer is folded in two or four.

Abstract: Provided is a secondary battery in which a single-layer secondary cell has an all-solid-state secondary cell structure with a storage layer sandwiched between a positive electrode layer and a negative electrode layer and which is superior to a conventional secondary battery with respect to at least one of volume, operation, and positioning. The present invention provides a secondary battery including a folded single-layer secondary cell formed by folding a sheet-shaped single-layer secondary cell, with a storage layer sandwiched between a positive electrode layer and a negative electrode layer, two or more times while alternately reversing the folding direction.
