Abstract:
The present invention provides a load measuring device and method capable of measuring, in real time, the load of a vehicle having a suspension with two-stage springs. The invention allows: sensors to be installed in both main springs and auxiliary springs of the suspension which has two-stages; and the weight, which is applied to the vehicle, to be measured by using measurement values of the sensors installed in the main springs and measurement values of the sensors installed in the auxiliary springs, wherein the measurement values are changed as the load is applied to the vehicle. Particularly, the invention adopts; a load measuring method using sensor values of the main springs or sensor values of the auxiliary springs in each load section of the vehicle; or a method for measuring the load that is applied to the vehicle by adding up the sensor measurement values of the main springs and the sensor measurement values of the auxiliary springs such that a mathematical formula capable of changing the added measurement values into the load is modeled, thereby calculating the applied load in real time by using the measurement values of the sensors, which are changed in real time according to the load that is applied to the vehicle, and outputting the calculated load to a user. Thus, even for conventional vehicles having a suspension with two-stage springs, to which the method for measuring the load of the vehicle in real time is difficult to apply, the invention can measure the exact load of the vehicle in real time, thereby effectively preventing an overload.
Abstract:
The present invention relates to a current-collecting apparatus including an active EMF-shielding function for an online electric vehicle, and more particularly, to a current-collecting apparatus including an active EMF-shielding function for an online electric vehicle, in which a current-collecting coil is wound in the direction opposite to a secondary current-collecting coil so as to enable current to flow in the direction opposite to the direction of the current flowing along the secondary current-collecting coil, thereby reducing EMFs. According to the present invention, a sudden increase in EMFs is prevented even when the current-collecting apparatus for an electric vehicle consumes electric power in addition to an operation of a power-supplying apparatus, and delivers the electric power to a load, thereby operating the online electric vehicle in a safer and more efficient manner.

The present invention pertains to a defect inspecting device, which comprises: a first optical unit for collimating each pair of rays so as to irradiate the same to an inspection position of an object to be inspected, wherein the pair of rays overlap each other at the edges thereof so that the overlapped areas is irradiated to the inspection position, a second optical unit for collimating each pair of rays so as to irradiate the same to the inspection position, wherein the pair of rays overlap each other at the edges thereof so that the overlapped area is irradiated to the inspection position; a control section for controlling the first optical unit and the second optical unit to be lighted alternately; and a camera for photographing the image of the inspection position using the incident light which is irradiated from the first optical unit or the second optical unit and then reflected from the inspection position.
Abstract:
The present invention relates to a front retainer which is fitted to the door of a carrier for receiving substrates. The disclosed invention comprises: a frame which is joined to the door; an extending part which is formed so as to constitute a plurality of rows on the inside of the frame; a first substrate holding part which is formed on the extending part; and a second substrate holding part which is formed between the frame and the first substrate holding part on the extending part. Formed on the first substrate holding part there is a U-shaped first recess, and provided on the second substrate holding part there is a V-shaped second substrate holding part. The front retainer of the present invention has the advantage that it prevents scratching and abrasion of substrates and therefore minimises the occurrence of particles due to shocks to the front retainer and substrates, while holding the substrates stable during the process of shutting the door or transporting the carrier.
Abstract:
The present invention relates to a wafer-conveying container for holding and conveying wafers; comprising a main body which is formed with a clamping opening on the inside of an open end surface of the main body, a door which is fastened on the inside of the open end surface, and a locking device for fastening the door to the main body. The locking device comprises a base, a rotational cam which is rotatably mounted on the base, a pair of arms which perform a linear motion on the inside and the outside of the door due to the rotation of the rotational cam, and a pair of cam-shaped projecting parts which respectively are rotatably mounted on the two end parts of the base and rotate by means of the linear motion of the arms and are inserted into the clamping opening of the main body. The rotational cam is maintained in a fixed position, out of the disengaged position and the locked position, by having a latching part of the rotational cam latch onto the projecting parts of the base between the disengaged position and the locked position.
Abstract:
The present invention relates to a spinal fixation apparatus inserted in a patient to fix the spine of the patient, and more particularly, to a spinal fixation apparatus in which an upper portion of a screw unit fixed at the spine is completely covered by an inner cap unit when a head unit and a fixing cap unit are coupled together, such that the upper portion of the screw is fixed and the motion thereof is controlled by the inner cap unit, and in which an engagement structure between the head unit and the fixing cap unit is reinforced to achieve a reinforced binding force of the spinal fixation apparatus. The spinal fixation apparatus of the present invention comprises: said screw unit, the upper portion of which has a spherical joint; said head unit having a rod accommodating groove, the size of which enables the insertion of a spine rod; said fixing cap unit coupled to the head unit to prevent the spine rod from escaping; and said inner cap unit, which is fitted into an insertion hole formed through the lower portion of the head unit, and which has a joint-accommodating hole, the size of which enables the insertion of the spherical joint so as to cover and fasten the spherical joint when the head unit and the fixing cap unit are coupled and engaged with one another. The inner cap unit includes: a main body having a rod-mounting recess in which the spine rod is mounted; a fastening side wall covering the outer surface of the spherical joint; a fastening gap for dividing the fastening side wall from the adjacent fastening side wall; and a press end formed at the lower end of the fastening side wall to fasten the lower portion of the spherical joint and to control the motion of the spherical joint.
