Abstract:
A cylinder 12 is positioned along the vertical axis. A piston 16 and a trigger 18 are provided respectively with a pair of racks 40 capable of meshing with a pair of pinions 38 of a housing 14. By way of the pinion pair 38, pivoting motion of the trigger can be converted into a reciprocating movement of the piston along the vertical axis. It is thus possible to increase the amount of discharge of liquid in one stroke of the trigger without inducing for example a drop in operability upon molding.
Abstract:
A push-type dispenser, in which the primary valve has a rod extending in the piston, and the secondary valve is mounted on the primary valve, is provided in the piston and can move in interlock with the primary valve due to the friction between it and the primary valve. A stopper formed on the piston and located above the secondary valve kicks the secondary valve, releasing the secondary valve from interlock with the primary valve and pushing the secondary valve downwards along with the piston. The secondary valve is closed with a delay after the nozzle head and the piston start moving upward. The primary valve is prevented from opening until the secondary valve is closed, thereby to suck the residual liquid back into the cylinder from the nozzle and the piston.
Abstract:
A control device for maintaining a constant speed of an automobile, having an internal combustion engine with a throttle valve and an actuator for the throttle valve. A degree of opening of the throttle valve is decided to bring the speed of the automobile to a desired set speed, corrected in accordance with running conditions by cyclically repeating an integral calculation at a first pattern to provide an integral correction value when a difference exists between the detected speed and the set speed. This integral correcting value is quickly returned at a second pattern greater than the first pattern when the integral correction value becomes greater than a predetermined value and the relationship between the detected speed and the set speed is reversed.
Abstract:
A trigger type sprayer which comprises a sprayer body whose inner lateral walls are provided with a pair of mutually facing engagement grooves, and wherein a trigger of the sprayer has a notch cut out in the upper end portion of the front wall and a pair of lugs formed on the outside of the upper end portions of the lateral walls. A nozzle fixed to the sprayer body extends outward through the notched portion of the trigger, and has a pair of axially extending stoppers integrally formed on the outer surface of the nozzle. The trigger can be rotatably connected to the sprayer body with ease due to the paired lugs being snap-fitted to the engagement grooves of the sprayer body and the upper end portions of the lateral walls of the trigger are prevented from being thrown inward by the stoppers of the nozzle and inconsequence coming off the sprayer body.
Abstract:
A trigger-type sprayer according to the present invention sucks up, pressurizes and sprays a liquid contained in a container having a mouth portion. The sprayer is provided with a housing attached to the mouth portion of the container, a trigger rockably attached to one end portion of the housing, a nozzle formed on the trigger and having an orifice, a cylinder supported at the middle portion on the housing and capable of facing the orifice, a suction tube attached to the other end portion of the cylinder and connecting the interior of the cylinder and that of the container, a piston one end of which is connected to the nozzle and the other end of which is located in the cylinder, the piston slidably touching the inner surface of the cylinder, a primary valve for selectively connecting the suction tube and the cylinder, and a secondary valve for selectively connecting the cylinder and the piston. The housing, trigger, nozzle, cylinder and suction tube are integrally formed.

A semiconductor device has a structure in which a light-emitting layer of an organic material or the like is sandwiched between a work function controlled single-wall carbon nanotube cathode encapsulating a donor having a low ionization potential and a work function controlled single-wall carbon nanotube anode encapsulating an acceptor having a high electron affinity. A semiconductor device represented by an organic field-effect light-emitting element and a method of manufacturing the same are provided. The semiconductor device and the method of manufacturing the same make it possible to improve characteristics and performance, such as reduction in light-emission starting voltage and a high luminous efficiency, to improve reliability, such as an increase in life, and to improve productivity, such as reduction in manufacturing cost.
Abstract:
An optical measurement of a crystalline sample to be measured. The sample is irradiated with an exciting light from the polarization direction in which the Raman scattering is prohibited by the selection rule. When a metal probe is brought to proximity to the sample to be measured, the selection rule is eased locally only in the proximity portion near the probe end in order that Raman scattering becomes active. Thus, a Raman signal only from the proximity portion near the probe end is detected. An optical measurement apparatus having an optical arrangement for measuring a signal light re-emitted from a sample to be measured when the sample is irradiated with an exciting light is provided. The optical measurement apparatus comprises a means for limiting the polarization state of the exciting light or signal light and a means for bringing a metal probe near the sample to be measured. The optical measurement apparatus is used to measure the signal light obtained by locally easing the limitation on the polarization state by bringing the metal probe near the sample. Therefore, Raman scattering light from silicon or the like can be measured with high space-resolution exceeding the light diffraction limit.
Abstract:
A high-resolution patterning method of a resist layer is disclosed by patternwise irradiation of the resist layer with electron beams utilizing a methanofullerene compound as the electron beam resist material, which is graphitized and made insoluble in an organic solvent by the electron beam irradiation in a dose of, for example, 1.times.10.sup.-4 C/cm.sup.2 or larger. The thus formed resist layer is highly resistant against dry etching to ensure utilizability of the method in the fine patterning work for the manufacture of semiconductor devices.
