Claims1.

A honeycomb-structured body for cleaning exhaust gas discharged from aninternal combustion engine, the honeycomb-structured body comprising:a metal frame (2) that includes a metallic outer peripheral wall portion (20)formed in a cylindrical shape and a plurality of metal plate-like portions (21) provided
inside the outer peripheral wall portion and in which the space inside the outer
peripheral wall portion is divided by the plate-like portions into a plurality of divided
spaces (S) that pass therethrough in the axial direction of the outer peripheral wall
portion; andhoneycomb units (3) accommodated in the individual divided spaces,
wherein the honeycomb units have polygonal-grid cell walls (30), and aplurality of cells (31) partitioned by the cell walls and serving as flow paths of theexhaust gas are formed in the honeycomb units, andwherein the honeycomb units are formed of a cocatalyst-containing basematerial (33) containing a cocatalyst comprising a composite oxide containing at leastcerium and zirconium and an inorganic binder that binds particles of the cocatalyst
together.
2.

The honeycomb-structured body according to claim 1, wherein the content of

the composite oxide in the honeycomb units is 50 to 98 mass %.

【問 2】[0004]
However, with respect to the lithium ion secondary battery equipped with a positiveelectrode containing a positive electrode active material which operates at a highpotential, where the positive electrode potential in a fully charged state exceeds 4.25 V(hereinafter, also referred to as "high-voltage lithium ion secondary battery"), it has
been found that oxidative decomposition of carbonate-based solvent contained in anelectrolytic solution for a lithium ion secondary battery generally occurs at the surfaceof the positive electrode, resulting in the problems that the cycle life of the battery isreduced, and gas is generated in each part of the battery. Therefore, it is difficult to use

conventional electrolytes in a high-voltage lithium ion secondary battery, and there is ademand for a new electrolytic solution （electrolyte） whose oxidative decomposition at
the positive electrode is suppressed.
[0005]In Patent Document 2, a method for suppressing the decomposition of a non-aqueous
electrolyte on the positive electrode side by using a non-aqueous electrolyte containing a
specific phosphoric acid ester compound has been proposed. Specifically, improvement ofoxidation resistance of the non-aqueous electrolyte has been attempted by adding 5
mass % of tris(2-propenyl) phosphate relative to the non-aqueous electrolyte.
In Patent Document 3, a method for improving the high-temperature cycle
characteristics of a lithium-ion secondary battery by using a non-aqueous electrolyte
containing a specific unsaturated phosphoric acid ester compound has been proposed.
Specifically, improvement of the high-temperature cycle characteristics by adding 1
mass % of tris(2-propynyl) phosphate relative to the non-aqueous electrolyte has beendescribed.
【問 3】[0010]The scintillator crystal according to the present invention contains

manganese, which is the heaviest element that forms the crystal. Manganese has an
atomic number of 25; no other scintillator crystal composed only of such light elements
is known. Conventional scintillator crystals have high absorption coefficients and thus,
for example, absorb X-rays only near the incident surface, and the atoms inside thecrystal do not contribute to the detection of X-rays. In contrast, the scintillator crystal
according to the present invention has a low absorption coefficient and thus allows
X-rays to penetrate deep into the scintillator crystal, so that a large number of atoms
will contribute to scintillation.
[0011]

Manganese is added in an amount of 0.1 to 5.0 mole percent, preferably 0.5 to

4.0 mole percent, per mole of the matrix. This amount serves merely as a guide forpreparing the crystal and may differ slightly from the manganese content of theresulting crystal since it is not fully understood in what form manganese is present in
the matrix.
【問 4】
Thermal Shrinkage
Straight lines with a length of 100 mm were drawn on test pieces (15 mm × 120 mmfilms) in the machine direction (MD) and the transverse direction (TD). After the test

pieces were left standing under standard conditions (23 °C and 50% RH) for two hours,
the lengths of the straight lines before the test were measured. The test pieces werethen left standing in a hot-air circulating oven set to 150 °C, 180 °C, or 200 °C for 30
minutes, with one corner of each test piece supported. The test pieces were thenremoved from the oven and were allowed to cool under standard conditions for twohours. Thereafter, the length of each straight line was measured, and the change inlength was calculated from the length measured before the test. The thermal shrinkage
R2 was calculated as the percent change in length after the test. Positive values of R2
indicate shrinkage.
Excellent: absolute value of R2 ≤ 1.5% (best)
Good: 1.5% < absolute value of R2 ≤ 2.0% (good)
Fair: 2.0% < absolute value of R2 ≤ 2.5% (acceptable for practical use)
Poor: 2.5% < absolute value of R2 (unacceptable for practical use)
