摘要:
An electrocatalyst for ethanol oxidization includes an elemental mixture containing platinum and ruthenium and at least one element, wherein the foregoing at least one element is selected from the group of tungsten, tin, molybdenum, copper, gold, manganese, and vanadium.
摘要:
A conjugated enzyme electrode comprising diaphorase and an amino-acid dehydrogenase immobilized on a conductive support by a polyfunctional aldehyde is disclosed, by which amino acids can be rapidly determined with high sensitivity.
摘要:
A camera with a voice command system includes a switch which selectively brings the voice command system to one of learning and working modes. During the learning mode, various command voices spoken into a microphone and each registered in the camera at a designated section. During the working mode, a spoken command voice is compared with each one of the registered command voices and recognized by the one that correlates mostly for generating a control signal relying on the identified section.
摘要:
A coin packaging machine where a predetermined number of coins accumulated in columnar form in an accumulating cylinder are supported by a supporting rod. A packaging paper is wrapped around the periphery of the columnar assembly of accumulated coins and both ends of the paper are folded and clamped (per amendment) rod is used for supporting accumulated coins not only for guiding of the accumulated coins from the accumulating cylinder to the packaging zone but also supporting of the accumulated coins in the packaging zone during rotation of the accumulated coins. A concave groove for the insertion of a clamping claw is formed in the side face of said supporting rod.
摘要:
In a paper delivery roller system, frictional surfaces of a pair of rollers are composed of the same material and the length of frictional surfaces of the feed roller is longer than the length of the frictional surface of the return roller.
摘要:
A note counting device includes cam grooves provided on side plates thereof. A front lid is pivoted to a note storage box for opening or closing a front opening of the box and has projections adapted to engage the cam grooves upon attachment of the box to the note counting device. During movement of the note storage box along guide means of the note counting device, the front lid is first unlocked and the projections are then displaced by the cam grooves to swing the front lid about the pivot to an opened position.
摘要:
A membrane-electrode assembly (MEA) 1 has a solid polymer electrolyte membrane 2. The membrane 2 has ion-conductive domains 3 and non-ion-conductive domains 4 and an electrode catalyst 5. The electrode catalyst 5 is present selectively on surface sites of the solid polymer electrolyte membrane 2 which corresponds to the ion-conductive domains 3 rather than surface sites of the membrane 2 which corresponds to the non-ion-conductive domains 4. A spray liquid containing the electrode catalyst and a solvent is applied onto a surface of the membrane 2 by electrostatic spray deposition to selectively adhere the electrode catalyst 5 on the surface sites of the membrane 2 which corresponds to the ion-conductive domains 3. The membrane 2 is preferably subjected to a hydrophilization treatment before being sprayed with the spray liquid.
