An epoxy resin obtained by a reaction of an epoxy resin monomer having a mesogen backbone and having two glycidyl groups in one molecule with a divalent phenol compound having, as substituents, two hydroxyl groups on one benzene ring, in which a number average molecular weight in gel permeation chromatographic measurement is from 600 to 2,500.

Epoxy resin, epoxy resin composition, inorganic filler-containing epoxy resin composition, resin sheet, cured product, and epoxy compound

The present disclosure provides: an epoxy resin molding material including; an epoxy resin having a mesogen structure, a phenolic curing agent, an inorganic filler, and a curing accelerator having a quaternary phosphonium cation represented by the following Formula (I); a molded product and a molded cured product using the epoxy resin molding material; and a method for producing a molded cured product. In Formula (I), each of Rto Rindependently represents an alkyl group having from 1 to 6 carbon atoms, or an aryl group, and the alkyl group and the aryl group may have a substituent. 

Epoxy resin molding material, molded product, molded cured product, and method for producing molded cured product

Provided is an epoxy resin composition including an epoxy resin and a curing agent, in which the epoxy resin contains a multimeric compound having at least one selected from the group consisting of a structural unit represented by the following Formula (IA) and a structural unit represented by the following Formula (IB), the multimeric compound contains a dimeric compound containing two structural units represented by the following Formula (II) in one molecule, and a ratio of the dimeric compound is from 15% by mass to 28% by mass with respect to the epoxy resin as a whole. 

Epoxy resin composition, semi-cured epoxy resin composition, cured epoxy resin composition, molded article, and cured molded article

Provided is a phenolic resin composition containing: an epoxy resin curing agent that contains a hydroxybenzene derivative represented by the following Formula (I) and a phenol resin having at least one partial structure selected from the group consisting of the following Formulae (IIa), (IIb), (IIc) and (IId); and an epoxy resin. In these Formulae, each of R, R, R, Rand Rindependently represents a hydroxy group, a hydrogen atom or an alkyl group; at least two of R, R, R, Rand Rare hydroxy groups; each Ar independently represents at least one group selected from the group consisting of the following Formulae (IIIa) and (IIIb); each of Rand Rindependently represents a hydrogen atom or a hydroxy group; and each of Rand Rindependently represents a hydrogen atom or an alkyl group. 

Phenolic resin composition

A coin treating device, wherein a key cylinder type locking means for limiting the release of the latch of the latch means is disposed in a coin storage unit so that the coin storage unit cannot easily be removed from a device main body other than in some specific cases.

Coin treating device

A coin assorter ( ), wherein a particular coin route ( ) having a coin retaining mechanism ( ) disposed therein is formed, meanderingly generally in S-shape, on the upstream side of the coin retaining mechanism ( ) to set longer the route length of the particular coin route ( ) having the coin retaining mechanism ( ) disposed therein in order to increase the number of coins (C) temporarily retained in the route length.

Coin assorter

A coin sorter, wherein three distributing levers ( ) are connected to each other through a link means ( ) so that the number of the driving means thereof is not increased even when the number of the distributing lever is increased and driven interlockingly with each other by a single solenoid ( ) operating one of the three distributing levers ( ).

Coin sorter

A coin detaining portion for temporarily detaining inserted coins passing through a coin sorting passage is situated adjacent to the denomination separating portion situated at the farthest upstream location of the coin sorting passage having arranged therein a plurality of denomination separating portions for separating inserted coins identified as genuine into different coin passages on the basis of their denomination.
