Abstract: Disclosed is an experimentation table integrated with a harmful gas reduction and air purification system. More particularly, the experimentation table integrated with a harmful gas reduction and air purification system includes a medicine shelf installed above a workbench; pillar parts formed on opposite sides of the workbench to support the medicine shelf; and an air purification system that ensures that harmful gases generated from the workbench are discharged through a lower space of the chemical shelf and inner spaces of the pillars, wherein the air purification system includes an intake grill formed using a lower space of the medicine shelf; an intake duct installed to communicate with an intake grill using inner spaces of the pillar parts; and a dust collection device installed in a lower space of the workbench and connected to the intake duct.

Abstract: Provided are a particle measurement apparatus having a plurality of apertures arranged in series therein, and a particle measurement method using the same to statistically analyze multiple signals generated when a particle passes through the plurality of apertures, thus acquiring more accurate information on particles. The particle measurement apparatus includes a plurality of aperture members arranged in series, a plurality of electrodes to form an electric field within the plurality of aperture members, and an analyzer for statistically analyzing multiple electrical signals generated when a particle passes through the plurality of aperture members.

Abstract: A sample analysis apparatus configured to automatically press a start button upon installation of a sample tube is provided. The sample analysis apparatus includes: a body of the sample analysis apparatus; a door housing which may be provided in an opened state or a closed state, and configured to be coupled to the body of the sample analysis apparatus by a hinge; a tube accommodating unit included in the door housing and configured to accommodate the sample tube; a start button included in the body of the sample analysis apparatus and configured to start analysis of the sample; and an operating member positioned at a first position which is distant from the start button the sample tube is not installed in the tube accommodating unit, and a second position which is configured to operate the start button when a sample tube is installed and the door housing is closed.

Abstract: A microfluidic device having a chamber with a fluid discharge configuration is provided. The microfluidic device includes a platform including a chamber configured to accommodate a fluid therein. The chamber includes an inner sidewall and an outer sidewall disposed outwardly from the inner sidewall in a radial direction of the platform. The outer sidewall includes a first point located closest to a center of the platform, and a second point located farthest from the center of the platform. A distance from the center of the platform to an arbitrary third point on the outer sidewall between the first point and the second point increases from the first point to the second point, so that the fluid near the first point is guided to the second point by centrifugal force during rotation of the platform.

Abstract: A method for manufacturing shoes is provided. The method includes preparing an upper and an outsole, applying an adhesive agent to the outer surface of an upper seal portion and the inner surface of an outsole seal portion, stitching together the outer surface of the upper seal portion and inner surface of the outsole seal portion, activating the adhesive agent by applying heat to the stitched seal portions, and molding the upper and the outsole by using a molding machine. Therefore, since the amount of the upper can be reduced and a separate insole is not necessary, the total weight of the shoes can also be reduced. The flexibility of shoes can also be enhanced.

Abstract: A chip removing device used in an electro-discharge machining using a discharge electrode. The device comprising a lower plate adapted to be disposed to the surface of the workpiece to be machined, an upper plate having an inner surface defining a cavity, and a machining oil chamber adapted to communicate with a gap defined between a discharge electrode and the portion of workpiece machined by the discharge electrode and supply machining oil under pressure thereto. The machining oil chamber is defined by the cavity and the outer surface portion of the discharge electrode exposed to the cavity as the discharge electrode penetrates the upper plate and the lower plate during the electro-discharge machining. A nipple is also provide for communicating with the machining oil chamber and supplying machining oil under pressure from a machining oil supply thereto. As machining oil under pressure is supplied to the gap, the removal of chip is effectively achieved.

Abstract: A safety window for a car which is capable of being automatically moved to its window closing position when the car speed exceeds a predetermined speed. The safety window comprises a control device for controlling the operation of the power window, which comprises a sensor for detecting a car speed, a comparator for comparing the car speed with a predetermined window closing car speed, and a power supply circuit for supplying the reference voltage to the comparator in an automatic window operation mode. The power supply circuit includes a select switch provided with a manual operation contact and an automatic operation contact, a reference voltage generator connected to the automatic operation contact and adapted to generate the reference voltage in the automatic window operation mode, and a limit switch adapted to send selectively the reference voltage from the reference voltage generator to the comparator.
