Abstract:
A trigger type sprayer comprises a nozzle cover integrally formed with the nozzle and connected to the nozzle through an integral hinge. The nozzle cover includes a seal section for sealing the ejection hole of the nozzle. An engagement section is provided on the nozzle which snap-fits with a first lock section on the nozzle cover. A second lock section is provided in the nozzle cover which is snap-fittingly engageable with a hole in the upper surface of the sprayer body, whereby the nozzle cover is pivotable about the integral hinge and is lockable in either a nozzle-sealing position or a nozzle-opening position.
Abstract:
A sprayer wherein there is formed in a sprayer body a pressurizing cylinder defining a pressurizing chamber communicating with a pressure accumulating chamber defined by a pressurizing cylinder in which a valve rod is slidably received. The pressurizing cylinder has a smaller diameter than the pressure accumulating cylinder. A piston is slidably inserted into the pressurizing cylinder. When liquid received in the pressurizing chamber is pressurized by bringing down the piston in the smaller diameter pressurizing cylinder, then a higher pressure than the pressing force of the piston is applied by Pascal's principle to the valve rod against the urging force of a pressure accumulating spring disposed behind the valve rod, because the valve rod has a larger diameter than the piston. When the high pressure is applied to the pressure accumulating spring, then a highly pressurized liquid can be sprayed, though the piston itself applies a relatively low pressing force. Since the pressure accumulating spring is received in the larger diameter pressure accumulating cylinder, a spring having a large pressure accumulating capacity can be used.

A depress button type sprayer comprises a piston slidably inserted into a cylinder and provided with a liquid jetting nozzle, a lever for moving the piston into the cylinder against the force of a spring and a depress button for operating the lever.
Abstract:
A semiconductor graphene is used for a channel layer, and a metal graphene is used for electrode layers for a source, a drain, and a gate which serve as interconnections as well. An oxide is used for a gate insulating layer. The channel layer and the electrode layers are located on the same plane.
Abstract:
A trigger-type pump dispenser capable of preventing deformation of a channel of a coupling part when a piston is vertically pushed down by a trigger even in a structure in which the coupling part bends and a nozzle does not vertically move. The dispenser has a base main body 1 having the cylinder part 11 inside and attachable to an opening part of a container main body. A cover body 4 detachably latched with the base main body. A piston structure 2 composed of the nozzle part 21 engaged with the base main body, the piston part 23, and a bendable coupling part coupling the nozzle part and the piston part. Many fins 22A are formed on the periphery of the coupling part 22 so that an interior channel is not deformed.

Abstract:
Disclosed is a microsize driving device in which falling of track proteins from an arrangement of motor protein molecules arranged on a linear track groove provided on a substrate is suppressed and utilization of kinetic energy of track proteins as a driving energy is made possible by controlling the moving direction to a single direction. Namely, provided is a microsize driving device which comprises a substrate, an arrangement of motor protein molecules such as, for example, kinesin molecules deposited on the bottom of a linear track groove provided thereon and track proteins such as, for example, microtubules disposed thereon and is characterized in that the said linear track groove has side surfaces shaped in such a structure as to permit a linear movement of the track proteins moving in a certain specific direction but to inhibit the track proteins moving in the reverse direction thereto causing reversion for the movement in the above mentioned specific direction.
Abstract:
A liquid discharging apparatus having a simple construction and capable of reducing the number of components with high efficiency is provided. The liquid discharging apparatus for discharging a liquid contained in a container from a nozzle head that is mounted on a cap attached to an opening of the container and is movable up and down together with a piston is characterized in comprising a virgin seal body positioned around a piston engagement hole formed on the cap and integrated with the cap so as to be separable from the cap by way of a thin portion, a vertical slit defined in the virgin seal body and having a pinch portion provided with a slip stopping portion at the opened portion thereof, wherein the nozzle head is fixed to its top dead center by the virgin seal body when the liquid discharging apparatus is not used.
