Electrical storage devices having excellent low-temperature properties can be obtained by using a quaternary salt (or ionic liquid) of general formula (1) below as an electrolyte salt for electrical storage devices or a liquid electrolyte for electrical storage devices. In formula (1), R1 to R4 are each independently an alkyl group of 1 to 5 carbons or an alkoxyalkyl group of the formula R′—O—(CH2)n—, with the proviso that at least one group from among R1 to R4 is the above alkoxyalkyl group. X is a nitrogen or phosphorus atom, and Y is a monovalent anion.

Disclosed is a resin composition wherein dispersibility of a modifying agent such as an inorganic substance is improved. The acid resistance of this resin composition is not deteriorated even when a modifying agent is blended therein. Specifically, the resin composition includes a base material having a cyano group-containing organic layer and an organic resin. This resin composition is extremely excellent in acid resistance when compared with organic resins which use a base material having an organic layer not containing a cyano group.

An electric double layer capacitor has a pair of current collectors, a positive polarizable electrode which is provided on one of the pair of current collectors, includes activated carbon of a weight W+ and has a capacitance C+, a negative polarizable electrode which is provided on the other of the pair of current collectors, includes activated carbon of a weight W− and has a capacitance C−, a separator interposed between the positive and negative polarizable electrodes, and an organic electrolytic solution which impregnates at least the positive and negative polarizable electrodes and the separator, wherein C−/C+=0.6 to 1.0 and W−/W+=1.1 to 2.0. Even when continuously charged at a high applied voltage, the electric double layer capacitor has a high retention of capacitance and a low rise in internal resistance, and thus has an excellent durability.

A mechanical brake actuator realizing the miniaturization of the entire device and the reduction of the parts costs is provided. When the brake lever rotates in the cable releasing direction, the connecting pin can be connected with the free end of the brake lever from one facing plate side while the other facing plate restricts the movement of the connecting pin, and the clip (30) is set on one facing plate (23b) so as to restrict the movement of the connecting pin after connecting the brake cable and the brake lever via the connecting pin.
摘要:
The presence or absence of methylation of C's in CpG dinucleotide in a sample DNA that contains a target sequence including the CpG dinucleotide is detected as follows. Multiple kinds of capture oligonucleotides immobilized on a base material and including: an oligonucleotide having a nucleotide sequence complimentary to or identical to a nucleotide sequence corresponding to the target sequence in which all of C's other than C's in the all of CpG dinucleotide are replaced with T's; and an oligonucleotide having a nucleotide sequence complimentary to or identical to a nucleotide sequence corresponding to the target sequence in which all of C's are replaced with T's are hybridized with the sample DNA in which non-methylated C's have been converted into U's by deamination or an amplification product thereof, and the presence or absence of methylation is detected based on the result of the hybridization.

摘要:
To provide the mechanical brake actuator enabling to downsize the device and to reduce the manufacturing costs of the parts. The mechanical brake actuator comprises the strut (23) which engages with one brake shoe (12) and has two facing plates (23b) with a strut-bridge (23a) connecting therebetween and the plate-like brake lever (24) which engages with the other brake shoe (13). The brake lever (24) is retained in the space (23c) between the facing strut plates and is pivotally supported on the strut (23), and the inner cable (41) of the brake cable (40) connected to the free end (24e) of the brake lever (24) via the connecting pin (43). The mechanical brake actuator which is operated by pulling the inner cable (41) comprises the clip (30), which attaches to the strut-bridge (23a) and restricts the rotation of the brake lever (24) in the cable releasing direction.
