Abstract: PURPOSE: A moving mass support structure for linear compressor is provided to prevent damage to components and improve compression performance by allowing the total force of the spring supporting the moving mass to change linearly in accordance with the increase of moving mass stroke. CONSTITUTION: A moving mass support structure comprises a moving mass(M) including a piston(40) for reciprocating within the gas compression space of a cylinder(20) by the driving force from a motor so as to compress the gas; and a non-linear mechanical spring(90) having a stiffness which increases in accordance with the increase of the stroke of the moving mass so as to compensate non-linear characteristics of a gas spring, and which supports elastically the moving mass. Thus, an overall spring force is applied linearly, to thereby accurately control the operation of the compressor.

Abstract: PURPOSE: A driving circuit of a solenoid valve is provided to secure stable driving of a solenoid valve by making uniform the peak currents flowing in a solenoid valve regardless of voltage change of a battery. CONSTITUTION: A solenoid valve driving circuit comprises: a capacitor(C1) charging the voltage supplied from a battery(VBB) with a uniform high voltage by a first transistor driven by a PWM(Pulse Width Modulation) signal; a second transistor(TR2) driven by the control of a control signal generating unit at an early stage of solenoid valve(SV) driving, and discharging the charge voltage of the capacitor to the solenoid valve; a third transistor(TR3) driven reverse to the second transistor, and providing the output voltage of the battery as a driving voltage of the solenoid valve; and a fourth transistor(TR4) driven by the solenoid driving signal of the control signal generating unit, and controlling the opening of the solenoid valve opened for the injection of fuel. The fourth transistor is driven by the PWM waveform outputted from the control signal generating unit to keep the open state of the solenoid valve. As the voltage outputted from the battery flows through the solenoid valve and the fourth transistor, the minimum current flows in the solenoid valve. Therefore, opening and shutoff time of the solenoid valve is kept uniform and fuel injection time is controlled accurately.

Abstract: PURPOSE: A separating plate for a fuel cell is provided which improves productivity, airtight property and cell efficiency and makes gas flow smooth. CONSTITUTION: The separating plate for a fuel cell comprises: (i) gas flowing-route(3) which is formed on each side; (ii) manifold(5) which is formed on each edge of the contour; (iii) a gasket(10) which is inserted into the contour of the gas flowing-route(3) and the manifold(5) to tightly seal with the anode and the cathode; (iv) a connecting passage(7) which is open formed in one united body with the gas flowing route(3) between the manifold(5) and the gas flowing-route(3); and (v) a thin plate(9) which is adhered to the open part of the connecting passage(7) to form an even part where the gasket is closely adhered.
