Title: Method for deciding life of lead battery
Inventor: IKUTA KOJI
IPC: G01R31/36
Filed: 1990-02-27
Abstract: PURPOSE:To decide a life by subtracting a ripple voltage caused by a ripple current from a voltage measured with the voltage measurement of internal impedance and calculating the internal impedance in the manner of dividing the obtained voltage difference by the measured current. CONSTITUTION:A measuring instrument 6 for internal impedance consisting of a constant AC current source 6-1 and an AC voltmeter 6-2 is connected to a lead battery 3, and when the internal impedance is measured by means of allowing the measuring current of constant AC current 1A with 60Hz frequency to flow and reading out the measured voltage by the AC voltmeter 6-2, it is learned that the measured voltage at the opened circuit state is being coincident with the voltage difference between the measured voltage at the floating charge state and the ripple voltage. Consequently, the internal impedance can be calculated by dividing this voltage difference by the measured current. When the internal impedance is larger than 1.28mOMEGA in either cases of opened circuit state or floating charge state, the life is decided as the limit.

Abstract: PURPOSE:To increase the wear resistance of a porous fired sheet composed of polytetrafluoroethylene, by adjusting the true specific gravity, endothermic peak on a crystal melting diagram according to differential scanning calorimetry and breaking strengths along the surface of the sheet and in the vertical direction thereof to have values within specified ranges. CONSTITUTION:A porous fired sheet of polytetrafluoroethylene (hereinafter referred to as PTFE) has a true specific gravity of 2.15-2.25, endothermic peak of 329-335 deg.C on a crystal melting diagram according to differential scanning calorimetry and breaking strength of 2kg/cm<2> or above along the surface of the sheet and in the vertical direction thereof. Said PTFE sheet is prepd. in the following manner. An appropriate amount of a liquid lubricant is added to PTFE powder and the mixture is molded into a sheet. The unfired sheet 1 is fed to a heating zone 3. While firing it by heating at a temp. not lower than the m.p. of PTFE in the zone 3, it is stretched by utilizing a difference in speed between pinch rolls 4, 5 on the inlet and outlet of the zone 3 (roll 5 being faster) to thereby make it porous, thus obtaining the desired sheet. The surface velocity of the pinch roll 4 is set to 1m/min or below.

Abstract: PURPOSE:To facilitate stripping operation of a light shielding mateial in the stage of stripping off the light shielding material from a light shielded container by bonding the light shielding container to the light shielding material so as to concentrate a stripping force to one point at at least the beginning of stripping. CONSTITUTION:A film package 10 is constituted of a light shielding container 14 for housing sheet film 12 and a strippable covering mateial 18 which shields light tightly to keep the film 12 isolated from light by covering an opening part 14a of the container 14. Since a bonded part 20a is formed obliquely to a direction orthogonal to the stripping direction of the material 18, the stripping force is concentrated in the first stage to one point of the oblique part 20, and the material 18 is stripped gradually from an end side of an end edge part 14b of the container 14 toward another end side. As the result, the material 18 is stripped without requiring relatively large tensile force. As described above, the light shielding material is stripped off very easily with small tensile force, and deterioration of light shielding effect before breaking seal is prevented.
