Abstract:
A closure member for a urea tank used to provide urea to an exhaust treatment system of a vehicle comprises a closure member body defining respective urea inlet and outlet passages and coolant inlet and outlet passages therethrough. A valve carried by the closure member body, and a portion of the valve can be an integral one piece part of the closure member body, selectively blocks the flow coolant through the interior of the urea tank. When coolant flows into the tank, it is separated from urea in the tank by a recirculating conduit which returns the coolant from the coolant inlet passage to the coolant outlet passage. Coolant circulating within the tank heats urea therein. The coolant flow valve can comprise a solenoid controlled valve with an electrical connector carried by the coolant tank for making connections to wiring that provides power to the solenoid to control the valve. The closure member can also carry a support, such as a downtube, that can contain temperature and level sensing components with the closure member supporting a connector coupled to wiring for such components.
Abstract:
A radiation-sensitive resin composition comprising a solution of an alkali-soluble resin and a radiation-sensitive compound in a solvent comprising a monooxymonocarboxylic acid ester. This composition has a high storage stability (i.e., a very small amount of fine particles are formed during storage) and is suited for use as a resist for making integrated circuits.
Abstract:
A positive type radiation-sensitive resin composition which comprises a 1,2-quinonediazide compound and an alkali-soluble novolac resin produced by poly-condensing phenols represented by the formulas (I) and (II) in a molar ratio of (I)/(II) of 1/99 to 100/0 with a carbonyl compound: ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, represent hydroxyl groups, hydrogen atoms, alkyl groups, aryl groups, aralkyl groups, alkenyl groups, halogen atoms, alkoxy groups, alkoxycarbonyl groups, aroxycarbonyl groups, alkanoyloxy groups, aroyloxy groups, acyl groups, cyano groups or nitro groups, ##STR2## wherein R.sup.3, R.sup.4 and R.sup.5, which may be the same or different, represent hydrogen atoms, alkyl groups, aryl groups, aralkyl groups, alkenyl groups, halogen atoms, alkoxy groups, alkoxycarbonyl groups, aroxycarbonyl groups, alkanoyloxy groups, aroyloxy groups, acyl groups, cyano groups or nitro groups. The above positive type radiation-sensitive resin composition is excellent in dry-etching resistance, resolution and heat resistance, and appropriate as a positive type resist for producing integrated circuits in which a resist pattern is formed, and also as a positive type resist for producing a mask.

Abstract:
A centralized management system for managing maintenance parts of machines at multiple plants includes: a warehouse facility for providing a concentrated storage of the maintenance parts for multiple types of the machines at multiple plants; a necessary parts management device for managing whether the maintenance parts are required for the machine; and a parts shipment management device for determining the maintenance parts to be shipped from the warehouse facility based on management information in the necessary parts management device. The present invention provides a system for managing maintenance parts that allows management costs to be restricted while allowing changes in the status of machines at plants to be handled in a flexible manner.
