Provided are an electrolytic solution for a nonaqueous electrolyte secondary battery and a nonaqueous electrolyte secondary battery each of which not only has heat resistance enough to resist reflow soldering but also can maintain the discharge capacity of the battery even in a low-temperature environment. The nonaqueous electrolyte secondary battery is provided with an electrolytic solution 50 including a solute and a solvent containing a polyethylene glycol dialkyl ether and an ethylene glycol dialkyl ether, a positive electrode 12, a negative electrode 26, and a separator 30 formed of glass fibers and placed between the positive electrode 12 and the negative electrode 26.

A method of manufacturing an optical element, comprising the steps of: preparing a mold having concave portions for molding a first resin into an optical member having a predetermined shape as well as a plate-like member having through-holes in at least a part thereof and being made of a second resin, and then disposing the plate-like member on the top surface of the mold so that at least one through-hole can face the concave portion of the mold; injecting a liquid precursor of the first resin into the space formed by the concave portion of the mold and the through-hole of the plate-like member so as to come into contact with at least a part of the plate-like member; polymerizing the liquid precursor while maintaining the contacting state of the liquid precursor with the plate-like member; and integratedly removing, from the mold, the plate-like member and the optical member made of the first resin which is the polymer of the liquid precursor, thereby to obtain an optical element.

In a nonaqueous-electrolyte secondary-battery that is soldered to a circuit board by a reflow soldering process, there has been a problem that when a secondary battery that requires discharging a after assembling the battery that requires discharging after assembling the battery is subjected to reflow, battery characteristics degrade due to heat treatment. Discharge voltage at the end of the discharging is made to be higher than a discharge voltage value that is an inflectional value at the end of a voltage plateau region indicating a cell reaction in a discharge curve (discharge capacity in abscissa and discharge voltage in ordinate) of initial discharge, thereby degradation of the battery characteristics due to the reflow hear treatment can be suppressed.
摘要:
A secondary battery or capacitor fitted with terminals and occupies less area on a packaging substrate. Either one of the positive and negative terminals is mounted within the outer surface of the secondary battery or capacitor. This reduces the area occupied by the secondary battery or capacitor fitted with terminals on the substrate. At least one step is formed on the terminal positioned opposite to the substrate. This prevents electrical shorting between the positive electrode can and the negative terminal.

A piezoelectric angular velocity meter includes a piezoelectric element. The piezoelectric element includes a first piezoelectric element and a second piezoelectric element bonded to the first piezoelectric element. The second piezoelectric element includes a second member made of a piezoelectric crystal, and upper- and lower-surface electrodes sandwiching the second member. The first piezoelectric element is fixed to the upper-surface electrode of said second piezoelectric element with an adhesive. The first piezoelectric element includes a first member made of a piezoelectric crystal, upper-surface electrodes, and a lower-surface electrode. The upper- and lower-surface electrodes sandwich the first member of the first piezoelectric element. The piezoelectric element is supported by two support portions.

An object of the invention is to enable high-speed feedback control by decreasing the mass of a cantilever including an axial driving actuator and eliminate drawbacks caused by the decrease in mass. In a so-called atomic force microscope for observing the surface shape of a sample using a signal corresponding to an interatomic force or the distance between a probe and the sample surface by bringing the probe of a cantilever to the vicinity of the sample surface held by a sample stage and performing two-dimensional scanning with the probe, a piezoelectric film sandwiched between a pair of electrodes is formed on the cantilever, and the piezoelectric film displaces the cantilever in a predetermined direction due to a d.sub.31 inverse piezoelectric effect upon application of a signal voltage to the electrodes.
