Abstract: A fork blade packing structure including a socket mounted in a bicycle fork blade at the top, a push block threaded onto a screw rod in the bicycle fork blade and supported on a spiral spring therein and moved vertically to adjust the spring force of the spiral spring, a connector mounted within the socket and having a threaded bottom end threaded into a top center screw hole on the push block and a top end extended out of socket through a hole thereof, a knob fixedly fastened to the top end of the connector outside the socket and adapted for turning the connector by a hand tool to force the push block upwards or downwards, and a guide wire mounted in an annular groove around the socket and having a guide top inserted through a radial through hole in the socket into a longitudinal sliding groove on the push block for guiding the movement of the push block.

Abstract: A heat-radiator for CPU of a computer, mainly including an air exhaust box, a collection funnel means and a bellows connecting the air exhaust box with the collection funnel means. An air blower and a detector means are disposed in the air exhaust box and connected by a circuit interface board inserted in an interface socket of the computer. The collection funnel means includes a heat-radiating plate located on the CPU, whereby the heat generated by the CPU is conducted through the heat-radiating plate and radiated therefrom to the ambient air and the hot air in the collection funnel means is sucked by the air blower to flow through the bellows and the air exhaust box to be exhausted from the computer housing.

Abstract: Disclosed is a system for preparing a route end node series which is equipped with a route search means 7 for preparing a node series, an intersection series or a combination of both as the data series for navigation, and a route end node series preparing means 3 for preparing the node series from the starting point and the destination to the respective nearest particular points. The route end node series preparing means 3 prepares node series by successively performing node search until the node nearest to the point indicated by the positional information on the starting point or the destination is attained. This construction makes it possible to perform course guidance through navigation based upon the node series between the starting point or the destination and the nearest intersection thereto even if the starting point or the destination is set at a point between intersections when particular points are set as intersections.

Abstract: A detachable electric fan and more particularly a built-up electric fan comprising component parts of detachable stand and one set of built-up blade-protective covers for easy carriage and storage; a stand being consisted of a transverse base plate having a connection trough at the top in the center with rib channels provided, and an independent vertical frame plate having a control switch button set mounted thereon and elastic retainers and reinforcing ribs at the bottom for connection with the base plate; the blade-protective cover symmetrically arranged, each blade-protective cover being composed of two semi-circular cover plates with one symmetric set of pin holder and locking pin for easy assembly, each blade-protective cover being supported with a circular supporting plate by bolts, the rear blade-protective cover having an axial hole for insertion of motor shaft to let the fan blades be well protected; by the built-up component parts to form a detachable electric fan for easy carriage and to reduce the
