    摘要： A needleless injection device includes an initiator valve controlling flow of compressed gas into a reservoir. A poppet valve connecting to the reservoir has a gas pressure regulation end to regulate flow from the initiator valve into the reservoir. A clamp piston is driven forward by gas pressure from the reservoir and causes jaws to clamp onto a plunger extending into an ampule. The poppet valve opens when reservoir pressure reaches the cracking pressure of the poppet valve. Gas from the reservoir rushes through the poppet valve into a drive chamber and forces a drive piston, containing the clamp piston and jaws, forward causing the plunger to slide into the ampule. A jet of injectant is discharged from the nozzle of the ampule and penetrates through the patient's skin. An improved method of needleless injection uses a specific pressure profile, ampule nozzle diameter, patient, injection site, and injectant parameters.

    摘要： Provided is a fuel cell having a structure in which a cathode and an anode face each other with a proton conductor therebetween. In this fuel cell, an oxygen reductase or the like is immobilized on at least the cathode, and the cathode is composed of a material having pores therein such as porous carbon. In this fuel cell, the volume of water contained in the cathode is controlled to be 70% or less of the volume of the pores of the cathode, whereby a high current value can be stably obtained through optimization of the amount of moisture contained in the cathode when an enzyme is immobilized on at least the cathode. Also provided is a method for operating the fuel cell.

    摘要： A needleless injection device has a housing containing a pilot valve connectable to a compressed gas source. A two stage power amplifying valve includes a main valve operatively connected to the pilot valve. The pilot valve and main valve form a two-stage valve with the pilot valve activatable to open the main valve utilizing gas pressure. Compressed gas in a reservoir flows through the open main valve to drive a plunger into an ampule to inject an injectant through a patient's skin. Interlocks are provided to resist inadvertent actuation of the device and a indicator indicates whether there is sufficient gas pressure in the device for another injection.

    摘要： The valve control unit of a fuel leakage preventing structure of the present invention includes first and second electrodes. The first electrode is attached to a first member that is movable. When a pressing force is applied to the first member to move, the first and second electrodes are brought into contact with each other, to cause conduction. The first and second electrodes are connected to a control device, and the control device opens a control valve when the first and second electrodes are put into a conducting state. As the control valve is opened and closed by a pressing force in this manner, a fuel solution can be easily supplied.
