A process for hydrogenating a sample in a pressure range below supercritical pressure values includes supplying at least a solvent of the sample to be hydrogenated by a feed pump with a constant volume rate into a flow path to create a base solution; adding the sample being dissolved into the flow path; feeding hydrogen into the flow path through a valve configured to transmit hydrogen only into a single direction; leading the dissolved sample in the presence of a catalyst through a hydrogenation reactor, where the reactor is inserted into a section of the flow path located after the hydrogen feeding position; maintaining the pressure of the reaction in a given pressure range by element of a pressure-adjusting unit, and collecting a hydrogenate formed within the hydrogenation reactor in a product receptacle connected to the end of the flow path.

A valve for a fuel pressure regulator includes a shaft defining a longitudinal axis. The shaft has a protuberance defining a mating surface that is positionable against a valve seat of the regulator and a flow surface that intersects the mating surface. A first angle is defined between the mating surface and a plane that is orthogonal to the longitudinal axis of the shaft. A second angle is defined between the flow surface and a plane that is orthogonal to the longitudinal axis. The first angle and the second angle are both oblique with respect to the longitudinal axis of the shaft.

A cooling method of an electronic device, the cooling method naturally circulating a cooling medium between an evaporator, which gasifies the cooling medium and cools heat-discharging air from the electronic device by heat exchange with the heat-discharging air, and a cooling tower or a condenser, which is disposed at a higher position than the evaporator and liquefies the gasified cooling medium, and subjecting a flow rate of the cooling-medium liquid supplied to the evaporator to valve control so that a temperature of the air obtained after the heat exchange and the cooling by the evaporator becomes a temperature suitable for an operating environment of the electronic device, wherein the improvement comprises that a condensation temperature or a condensation pressure of the cooling-medium gas in the cooling tower or the condenser is configured to be not varied even when the flow rate of the cooling-medium liquid supplied to the evaporator is subjected to the valve control.

A method of using a processing system that is operable to deposit liquid and to remove liquid by way of negative pressure. The method includes arranging a device to have at least one of the liquid deposited thereon by the processing system and the liquid removed therefrom by the processing system. The device has a sensor portion disposed thereon. The sensor portion can provide a sensor signal based on pressure related to the at least one of the liquid being deposited thereon by the processing system and the liquid being removed therefrom by the processing system. The method further includes performing at least one of depositing, by the processing system, the liquid onto the device and removing the liquid, by the processing system, from the device. The method still further includes providing the sensor signal, by the sensor portion, based on the pressure related to the at least one of the liquid being deposited onto the device and the liquid being removed from the device.

An auxiliary apparatus for a vehicle water tank is applicable to a cooling system. The auxiliary apparatus includes a water supply apparatus, a pressure relief apparatus, a state sensor, and a controller. The water supply apparatus has a feed-water pump and an auxiliary water tank. The cooling system and the auxiliary water tank respectively accommodate a cooling fluid. The pressure relief apparatus detects a pressure in the cooling system, and guides the cooling fluid in the cooling system to the auxiliary water tank when the pressure exceeds a predetermined pressure value. The state sensor detects a storage state of the cooling fluid in the cooling system. The controller stops the feed-water pump according to the storage state sensed by the state sensor, or starts the feed-water pump to guide the cooling fluid in the auxiliary water tank to the cooling system.

An automatic synthesis device for fluorine-18-ACETATE ([18F]fluoroacetate) consists of a machinery housing that has multiple reactors and multiple raw material containers, and uses multiple control valves between each reactor and container, and operates the control valves through a control system to charge the raw material from each container to each reactor in an automatic and sequential fashion to execute the six procedures: fluorination, azeotropic dewatering, synthesis (reaction with precursors), purification and separation, hydrolysis and neutralization, purification and collection. The operation simply requires adding raw materials to the containers in advance, turning on power, charging reactive gases. In 50 minutes, the process to produce the product will be completed. The operation is really simple and can effectively improve production efficiency.

An apparatus and method for producing a hydrogen-enriched reformate. The apparatus includes a fuel processor for converting a fuel to a reformate having fluctuations in pressure and or flow rate, means for reducing the fluctuations, a compression unit for compressing the reformate and one or more of a purification unit and a storage unit downstream of a compression unit. Means for reducing the fluctuations in the reformate can include one or more of a buffer and a conduit for providing a controlled flow of a supplemental fluid to an inlet of the compression unit. The supplemental fluid can include the compressed reformate, a hydrogen-enriched reformate, and mixtures thereof. The apparatus can include means for regulating power to the compression unit that can incrementally increase power to the compression unit particularly during start up. The purification unit can include one or more of a hydrogen selective membrane and a pressure swing adsorption unit. Methods for producing hydrogen are also disclosed.

In order to provide a gas generation apparatus such as a hydrogen gas generation apparatus for a fuel cell or an oxygen gas generation apparatus used in medical sites and at the time of disasters in which a solid gas generating agent such as metal is brought into contact with a reaction liquid to generate hydrogen gas or oxygen gas, a gas generation apparatus A having a solid gas generating agent and a reaction liquid in which the solid gas generating agent and the reaction liquid are stored respectively in separate storing vessels 21, 31 and in which the reaction liquid is supplied into the gas generating agent-storing vessel to generate gas by capillary-active connection of the respective storing vessels assumes a constitution in which capillary-active connection is shut off when a pressure of the gas is raised. In the above gas generation apparatus, generation of the gas can automatically be controlled by a simple mechanism when the gas is not consumed, and therefore generation of excessive gas can be controlled.

A particulate converter for the collection and the incineration of particulate matters from diesel engine exhaust includes an exhaust path extending from the diesel engine through the particulate converter. The particulate converter further includes a housing and at least one candle located in the housing. An electrical incineration system may be electrically connected to a pulsed power supply for incinerating soot collected within the candle. A diesel oxidation catalyst (DOC) may be disposed in the exhaust path to generate sufficient amount of NO2 to assist in incineration. At least one exhaust cooling device may be provided for the control of exhaust temperature. A feedback control system may control exhaust gas temperatures based on pressure drop across the DPC, temperature ahead of the DPC and engine RPM.
