In a hybrid type marine propulsion device including a main engine and a motor, low fuel consumption is realized by a compact configuration and highly efficient drive control.A marine propulsion device includes a clutch 7 provided on an input shaft 6 of a main engine, a horizontal input/output shaft 8 connected to the clutch, a vertical shaft 11 connected to the input/output shaft through an upper bevel gear 9, a horizontal propeller shaft 13 connected to a lower end of the vertical shaft through a lower bevel gear 12, and a propeller 14 at the other end side of the propeller shaft, in which the propeller is revolved around the vertical shaft to set a propulsion direction, wherein a motor generator 20 is mounted on a floor 3, and connected directly to the other end side of the input/output shaft. In a low rotation region, motor propulsion is performed, and in a high rotation region, hybrid propulsion in which the main engine is assisted by the motor is performed.
摘要:
A prescription filling assistance device useful for monitoring the filling of and distribution of drugs to patients in need of the drug, while restricting access to the drug by patients for whom the drug may be contraindicated are disclosed. Also disclosed is a drug information and management system for use with the prescription filling assistance device. Methods for delivering a drug to a patient in need of the drug, while restricting access to the drug by patients for whom the drug may be contraindicated are disclosed. In some of the disclosed methods, prescriptions for the drug are filled by a pharmacy only after a computer readable storage medium has been consulted to retrieve a prescription approval code. Embodiments are provided wherein the patients are assigned to risk groups based upon the risk that taking the drug will lead to an adverse side effect, and certain additional information, such as periodic surveys and diagnostic tests probative of the ongoing risk of the side effect developing are obtained before prescriptions for the drug are approved.

A method of performing a handoff between a plurality of wireless systems having different service areas and a wireless communication terminal are provided. A means for selecting one of the wireless systems to be connected according to the average moving speed of the wireless terminal is provided. When the average moving speed is changed across a certain threshold, the wireless terminal starts selecting one of the wireless systems as a handoff destination. Upon selection of the handoff destination, the current throughput is compared with the estimated throughput of the handoff destination. When an improvement in the throughput can be expected, the wireless terminal performs the handoff. The wireless terminal incorporates a plurality of control devices to select the handoff destination while communicating with the current wireless system.

A fuel cell power generating apparatus using a fuel cell (10) having a structure such that a cathode and an anode are disposed on opposite sides of a polymer electrolyte membrane, comprising: an air introduction passage (11) for introducing air to the cathode; an air discharge passage (15) for discharging, to the outside of the system, discharge gas containing reactant water generated at the cathode; a circulation passage (16) connected between the air discharge passage and the air introduction passage in order to again introduce at least a portion of the discharge gas flowing through the air discharge passage to the air introduction passage and thus to the cathode; a valve (17) provided for at least one of the air introduction passage and the air discharge passage; a temperature sensor (22) for measuring the temperature of the discharge gas from the cathode; an ampere meter (19) for measuring the level of an electric current output from the fuel cell; and a control unit (18) for controlling the degree of opening of the valve in accordance with the temperature of the discharge gas and the output level of the electric current measured respectively by the temperature sensor and the ampere meter. A portion of the discharge gas containing reactant water is circulated into the air introduction passage and thus to the cathode of the fuel cell to thereby humidify the electrolyte membrane, so that there is no need to supply water from the outside of the system. The apparatus is particularly suitable to be mounted on a vehicle.

Provided is a method for solubilizing cellulose in which cellulose can be solubilized in a short period of time with a low amount of excess decomposition and without the use of a catalyst or other chemicals. A starting material containing cellulose is pulverized to reduce the crystallization thereof, adjusted for moisture content, reacted with water in the absence of a catalyst, and converted into a water-soluble component. At this point, the reaction is performed at a temperature of 100° C. or more and less than 300° C., and a total pressure of 0.05 MPa or more and less than 10 MPa. Water is added and extracted from the water soluble component, and solid-liquid separation is performed to separate the solids and the aqueous solution.

In starting power generation under low temperature conditions, an antifreeze liquid being coolant of a cooling system in a fuel cell stack is once recovered in a tank to reduce heat capacity of the fuel cell stack, and thereafter the power generation is started. Heat of reaction caused by the power generation restores the temperature to temperature under normal operation, and then the antifreeze liquid is again filled to drive the cooling system, so as to make it function as a cooler.

A silica glass filter comprises a porous support body composed of amorphous silica particles as a porous sintered body and having a purity of 99.9% or more and containing 150 ppm or less in total of impurities including alkali, alkali metal, heavy metal and/or elements of III B group, and a filtration layer formed on the support body. The filtration layer is composed of amorphous silica particles as a porous sintered body in a fine mode and has substantially the same purity as that of the support body.
