  • Publication number: 20220281141
    Abstract: While a part of an article is crushed to be collected, a crushed pieces collector reduces the number of uncollected crushed pieces and the crushed pieces scattered over the floor to improve efficiency of collection and to prevent a foreign matter from being mixed into the collected crushed pieces. The crushed pieces collector is configured to collect the crushed pieces while a crush object is crushed to be removed from a fixed object to which the crush object is fixed. The crushed pieces collector includes: a receiving portion placed below the crush object to receive the crushed pieces; and a contact portion provided contiguously with the receiving portion and in contact with the fixed object. The contact portion includes an elastic body elastically deformable along an outer surface of the fixed object.

  • Patent number: 9520564
    Abstract: A bulk heterojunction-type organic photovoltaic cell, i.e., BHJ solar cell, has a photoelectric conversion layer containing a mixture of a donor domain and an acceptor domain. The donor domain contains a polymer as a donor (photoelectric conversion material), and the polymer is obtained by reaction of a polyphenylene represented by the following general formula (1). For example, the acceptor domain contains phenyl-C61-butyric acid methyl ester (PCBM) as an acceptor. At least one of R1 to R6 in the general formula (1) is an alkoxy group, and R7 to R10 independently represent a hydrogen atom, an alkyl group, or an alkoxy group.

  • Patent number: 8298720
    Abstract: A proton conductor is formed of a porous body as a substrate and proton-conducting polymer covalently bonded to inner surfaces of pores of the porous body. The proton-conducting polymer comprises a main chain and a plurality of branched side chains extending radially therefrom. The branched side chains are each bonded to a proton-conducting salt at the end. The proton-conducting polymer has a substantially cylindrical structure in which the salts can be circumscribed by a virtual circle having a center on the cross-sectional center of the main chain such that a radial direction of the virtual circle is perpendicular to a longitudinal direction of the main chain. The salts are located on the peripheral wall of the substantially cylindrical structure. Protons are transferred between the adjacent salts, so that a conduction channel is formed on the peripheral wall of the cylindrical structure.

  • Patent number: 7781535
    Abstract: An acidic group-containing polymer which has an acidic group such as sulfonic acid group, phosphoric acid group, and phosphonic acid group, and a proton acceptor which has a boiling point at 1 atmosphere higher than 100° C. and which functions as a medium for conducting proton dissociated from the acidic group are retained in pores of a porous member. Preferred examples of the proton acceptor include a salt structure composed of an anion and a cation derived from a basic organic compound, a basic organic compound, and a dissociation-facilitating polymer which facilitates dissociation of proton. Any one of the acidic group-containing polymer and the proton acceptor may be retained first, or both may be retained simultaneously.
