Abstract:
A two stage reciprocating compressor includes a casing. A first compressing unit is disposed in the casing and includes a first piston and a first cylinder, the first compressing unit being driven by a reciprocating motor to linearly reciprocate the first piston in the first cylinder to suck in and compress gas. A second compressing unit is disposed in the casing and includes a second piston and a second cylinder, the second compressing unit being driven by vibration of the first compressing unit to linearly reciprocate the second piston in the second cylinder to suck in and compress gas. A vibration transfer member transfers the vibration from the first compressing unit to the second compressing unit. The first and second compressing units extend in parallel and face in the same direction, the second compressing unit being located adjacent to a suction passage of the first compressing unit.
Abstract:
Disclosed herein is an insole for eliminating static electricity, which comprises a top layer made of conductive synthetic fabric, a middle layer made of antistatic soft foam, and a bottom layer made of hard synthetic resin, wherein a pair of ferroelectric elements and an electric discharge net are inserted between the soft foam middle layer and the hard synthetic resin layer. The insole has a simple structure, which can be simply used inall kinds of shoes, including not only general shoes, but also safety shoes for wearing in various industrial fields, and it can efficiently eliminate static electricity generated in the human body. Thus, the insole is advantageous in that it can prevent not only various accidents, such as firing explosion and a fire, which occur due to the generation of static electricity in industrial fields, but also various safety accidents, such as electric shocks, body injuries, and unpleasant sensations by electric discharge sound, which occur due to the generation of static electricity in daily life.

Abstract:
The present invention relates to a shock-absorbing insole for a footwear and a method of manufacturing the same wherein the shock-absorbing insole is disposed on the bottom surface in a footwear for absorbing and reducing the shocks applied from the ground to a wearer's sole during running, jogging, walking, etc. The shock-absorbing insole includes: a bottom plate made of a synthetic resin and having fabric attached on the top surface thereof; and a shock-absorbing member made of an elastic synthetic resin for absorbing shocks applied to the footwear in such a manner as to be contracted and restored from/to its original state in accordance with the load applied during walking, the shock-absorbing member being formed integrally with a bottom surface of a heel portion of the bottom plate.
Abstract:
A suction gas guiding (100) system for a reciprocating compressor (30) includes a gas guide conduit (110) penetrating an inner stator of a reciprocating motor and having both ends installed on a suction pipe (50) of a shell (10) and on an inner flowing passage of a piston (31) so as to guide the sucked gas inside the shell (10) to the inner flowing passage, whereby the refrigerant gas is sucked into the inner flowing passage of the piston through the gas guide conduit smoothly, and accordingly, the suction rate of the refrigerant gas is increased. Therefore the efficiency of the compressor (30) is increased. In addition, noise and vibration generated when the refrigerant gas is sucked are attenuated in the resonant spaces, and therefore the flow resistance against the noise and the gas, whereby the reliability and efficiency of the compressor is increased.
