Abstract:
A storing tank, in which the storage space can be multiplied to a suitable extent, and the area occupied by it can be reduced. It has a lower tank member, an access gate, a pushing mechanism, an upper tank member and an outlet. Material put in the access gate falls onto the pushing mechanism to be pushed upwardly into the lower tank member. When the latter is full, the upper tank member is moved upwardly by the increasing material to increase the receiving space until the upper tank member is moved to the highest position. When the outlet is opened, the material can automatically fall down along a bevel guiding surface in the lower tank member and out of the outlet.
Abstract:
A stabilizer bar unit for an automobile includes a stabilizer bar connected to the control arms of two aligned wheels of the automobile at two ends thereof. A cylindrical sleeve coaxially surrounds the intermediate portion of the bar in such a manner that two sealed annular chambers are formed in two end portions of the sleeve. Two movable rings are received movably within the chambers and have splined inner surfaces engaged with the splined outer surface of the intermediate portion of the bar, and splined outer surfaces engaged with the splined inner surface of the sleeve. The piston rod of a pivotally mounted hydraulic cylinder is connected rotatably to the sleeve. A hydraulic liquid is supplied from a reservoir to the cylinder through a conduit unit. An automatically controlled switch is disposed on the conduit unit so as to stop the intercommunication between the reservoir and the cylinder when the automobile is steered, accelerated or braked. An automatic control system moves the rings outward in response to the increase in the rotational speed of the wheels and moves the rings inward in response to the reduction of the rotational speed of the wheels. The portion of the bar between the rings cannot be twisted.
Abstract:
An automotive suspension system including a suspension cylinder installed between the automobile frame and the control arm of the automobile wheel; a hydraulic apparatus including two corresponding hydraulic cylinders each cylinder having a combination of a piston and a piston rod; a combination coil-spring and shock absorber member sandwiched between the two piston rods of the cylinders and being compressed thereby; and a control device for directing the flow of the hydraulic fluid from the suspension cylinder to either of the two cylinders. One of the cylinders has a sectional diameter which is larger than that of the suspension cylinder and the remaining cylinder has a sectional diameter which is smaller than that of the suspension cylinder. As the result of the effect provided by the control of the control device of the suspension system, an automobile using it will provide a good cushioning effect to the user(s) thereof and will minimize the risk of overswing or flipping when making a turn.
Abstract:
An air filtration system includes a main body having a flow path; a first filter portion provided on the flow path and having a first body portion; a plurality of protrusions distributed and disposed on the first body portion; and a plurality of first through holes passing through the first body portion and interposed between the adjacent protrusions; wherein when an external fluid flows in the flow path, the external fluid passes through the protrusions first and then passes through each of the first through holes, so that the flowing external fluid is hindered by the protrusions, and thus a flow velocity at a position adjacent to the protrusions is lower than a flow velocity flowing through the first through holes, thereby vortices are respectively generated between orifices of the first through holes and the adjacent protrusions.

Abstract:
An optical touch control system is disclosed. A reflector surrounds a monitor. At least one image detection module is adjacent to the monitor and includes an image sensor, a reflective mirror, and a light source. The image sensor is electrically connected to an image processor. The reflective mirror is disposed on the image sensor and inclines to the image sensor by a predetermined angle. The light source outputs light onto the monitor. The reflective mirror reflects the light reflected by the reflector to the image sensor, identifying a touch control operation.
Abstract:
An optical touch structure including a light guide element, a light source, a reflecting mirror, and an image sensor is provided. The light guide element has a light-emitting surface. The light guide element guides the light provided by the light source to the light-emitting surface. The extending direction of the reflecting mirror is substantially perpendicular to the light-emitting surface. The intersection of the reflecting mirror and the light guide element is defined as a first position. The light guide element and the reflecting mirror define a touch range. The image sensor is disposed on a second position opposite to the first position. The sensing area of the image sensor at least covers the touch range. When the proceeding path of the first direction light is shorter than that of the second direction light, the strength of the second direction light is larger than that of the first direction light.
