Abstract: Provided is a means capable of realizing a surface-roughening method for modifying the surface of a resin molded article to form a surficial layer, such as a coating or plating, or to impart a function derived from the surface configuration. The method comprises adding a resin composition and performing a post-treatment and is thus simpler and easier than conventional methods. The resin composition is a composition for resin surface roughening that contains an aliphatic polycarbonate and an alkali metal salt.

Abstract: General Formula (I) Provided is an all solid state secondary-battery additive comprising a polyalkylene carbonate (I) represented by general formula (I), and by providing such additive, properties such as the charge-discharge capacity and interfacial resistance of an all-solid-state secondary battery are improved. (In general formula (I), R1 and R2 are each a C1-10 chain-like alkylene group or C3-10 cycloalkylene group, m is 0, 1, or 2 and n is an integer of 10 to 15000, and each R1, R2 and m in the polyalkylene carbonate (I) chain is independently the same or different.

Abstract: A microparticle analysis apparatus includes at least: a detecting unit having one or a plurality of light sources and a plurality of photodetectors, configured to emit excitation light from the light sources, and to detect light emitted from microparticles on which the excitation light is irradiated, at the photodetectors; a first storage unit configured to store, for each microparticle, data detected at the photodetectors of the detecting unit based on detected time; and a second storage unit configured to store data relating to a particular microparticle of detected data stored in the first storage unit.

Abstract: A jog dial switch, which functions as a key switch, includes a key sheet, a rotatable key top arranged on the key sheet, and a movement amount detector for detecting movement amount of the key top. The movement amount detector includes four permanent magnets arranged on the key top, three Hall elements, and an electric circuit for processing signals output from the Hall elements. The Hall elements and the electric circuit are arranged below the key sheet. The key sheet is formed by a water resistant material and covers the electric circuit.

Abstract: A reservoir tank comprises a tank body and a double bottom. The tank body is constituted of a roof, a tank bottom plate and a tank wall. The roof and the tank bottom plate are fixed to the tank wall by welding. The double bottom includes a double bottom plate and a rim, which are fixed to each other by welding. A leakage liquid outlet is formed at one side of the double bottom plate on which reinforcement ribs are arranged in a lattice state. Cutouts are formed in the reinforcement ribs. The double bottom plate has a declivity so that the leakage liquid outlet is positioned at the lowermost level. The rim is provided with three detection ports. Upon welding the tank wall to the rim, the inside of the double bottom becomes an airtight state.

Abstract: A ring trip circuit is incorporated in a telephone exchanger together with a call signal source and a relay unit connected between the call signal source and user's terminal, and determines current status of the user's terminal at a certain timing close to the zero level of a call signal changed across the zero level without influence of fluctuation of the call signal source, a loop resistance and a leak resistance, thereby preventing the user's terminal from undesirable interruption of the call signal.
