Title: Method for blow molding of superplastic ceramics
Inventor: AZUMA KENJI
IPC: C04B41/80
Filed: 1992-10-14
Abstract: PURPOSE:To accurately produce a product of a complicated shape in a short time by calculating a gas pressure pattern according to a specific formula based on the information about individual characteristics of superplastic ceramics and then blow molding a ceramic thin sheet under prescribed conditions based on the gas pressure pattern. CONSTITUTION:Tensile tests are carried out at respective temperatures and strain rates to determine conditions under which a large elongation value at >=0.5(m) strain rate sensitivity index of stress regarded as showing the superplasticity. Tests are then performed based on the conditions to determine a change in the value of (m) following the deformation. The value of the constant (K) (expressed by the formula DELTA=Kepsilon'<m>) is then obtained therefrom. The gas pressure pattern (deltaP) is calculated from the formula [epsilon' is the strain rate; (h0) is the board thickness before forming; (r) is the radius of forming mold; (t) is the time] based on the information about the changes in values of the (m) and (K) due to the strain and other characteristics. The obtained ceramic thin sheet is then blow molded in a superplastic temperature region under a pressure within the resultant range and the molding time.

IPC: H01M10/48
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To prolong the cyclic lifetime of a secondary battery by controlling the charging and discharging so that the charge/discharge capacity of the battery is set less while the battery remains in the new condition and set greater with propagation of the battery degradation. SOLUTION: The frequency of charging and discharging of a secondary battery in the form of a digital signal is given by a capacity judging part 2 of a charge/ discharge control device 1, and a numerical value conversion part 9 of a charge/ discharge voltage setting part 3 sets the upper limit voltage value in charging and the lower limit voltage value in discharging in accordance with the given frequency of charging and discharging. The voltage of the battery 5 is compared with the set upper limit value, and a switch 15 is controlled through a charge/discharge command part 14, and charging of the battery 5 is controlled with the power supply 7. Discharging of the battery 5 is alike controlled, and by this control system, the charge/discharge capacity can be set less while the battery remains in new condition set greater in the course of battery degradation. Thus charging can be performed with the upper limit voltage value which is constant at all times, and the cyclic lifetime of the battery becomes longer than in the case discharge is made down to the specified lower limit voltage value.
