This invention provides the electromagnetic waves shield material that has a sufficient effect of shielding the electromagnetic waves by making the electric conductive fibers into mesh. And this invention also provides the electromagnetic waves shield mobile phone case that avoids a harmful effect on the human body without reducing the function of communication of the mobile phone used the said electromagnetic waves shield material.

The fibers with electric conductivity are woven into mesh by a general knitting machine like a machine for tricot. The cost is low even used for the wide area to shield the electromagnetic waves because the consumption of the fibers needed is less. The coarseness of the net is maintained the same by controlling the movement of the length and breadth each other.

To avoid the radiation to the head direction, the electromagnetic waves shield material is used for the front and upper sides of the mobile phone case which are the direction to the head when the mobile phone is in use. The regular material without electromagnetic waves shield effect is used for the both sides of the mobile phone case.

The antenna cap with electromagnetic shield structure is attached to the said upper side of the electromagnetic wave shield case. The electricity with high frequency is conducted between the above antenna cap and the upper side of the electromagnetic wave shield case. The said antenna cap is a conic tube cut it's head obliquely. The opening part is made to face in the opposite side of the head when it is attached to the antenna. A metallic pin is attached to the outside of the antenna cap. This metallic pin conducts high frequent electricity with the wire antenna at the mobile phone body when it is attached. It functions as an additional antenna to the wire antenna at the mobile phone body.

A person can safely descend from a burning high-rise building or the like using an inflatable flying body that has a hollow conical form in an inflated deployed condition, but is deflated and folded into a backpack form in a stowed condition. The flying body includes an upper stabilizing ring, a lower nose structure with a pneumatic damping body, spoke struts extending conically therebetween, a cover skin covering the abovementioned inflatable components to form the conical outer surface and provide aerodynamic braking drag, and gas generators to inflate the inflatable components. A person straps on the apparatus in the stowed backpack form and pulls a handle to actuate the gas generators for inflating the apparatus, whereby the expanding apparatus ejects the person from the building and then orients itself in a nose-down attitude during the descent. The pneumatic damping body damps and dissipates the landing impact energy.

A heat extraction and cooling system which can be attached to the central processing unit (CPU) of a computer for exchanging heat through an enclosure which houses a ducted fan. The apparatus includes a dual section rotary blade system that is driving by a conventional direct current motor. The apparatus also includes a heat conducting base that is placed in thermal engagement with the CPU. Attached to the base is a uniquely configured heat dissipating member which includes a plurality of upstanding heat dispensing fins, a generally conically shaped shroud and is provided with a plurality of apertures for drawing the flow of cooling air through the shroud and past the fins of the heat dissipating member. The dual section rotary blade system pulls air inwardly through the apertured shroud, past the heat dissipating fins and into the hub portion of the rotary blade system. The heat air is then forced into the interior of the uniquely configured, hollow blades which are attached to the hub portion. Each of the blades is provided with a leading edge portion and trailing edge portion having a plurality of small apertures formed therein. As the blades rotate, a negative pressure is formed proximate the trailing edge of each blade and the heated gases are expelled through the small apertures. This provides a jet thrust action to the rotating assembly and causes the heated gases expelled from the hollow blades to expand rapidly thereby producing an additional cooling effect.

The reusable insulating and sealing structure may also include a removable seal closure cap for removable positioning in the enlarged diameter open distal end of the frusto-conical seal, and an integrally molded tether connecting the removable seal closure cap to the frusto-conical seal adjacent the enlarged diameter open distal end thereof. The closure cap and tether permit the insulating and sealing structure to be sealed when a cable is not extending therethrough and thus permit the insulating and sealing structure to be reused.

A projectile for an air arm is integrally formed from a single piece of dense malleable material formed as a body of revolution about a longitudinal axis having a head portion dimensioned for free sliding in the bore of an air arm and a skirt-like portion of frusto-conical form. The rearward end of the skirt portion is dimensioned to be in slight interference fit with the bore and the forward end is joined with the head portion to define a reduced diameter waist. The frustum is shell-walled, having a central recess opening to the rear and extending forwardly into the head portion. The head portion has a parabolically shaped outer surface which transitions smoothly into a hyperbolically shaped outer skirt surface for aerodynamic efficiency. Vanes are formed on the head portion to enhance in-flight spiraling rotation.
