Abstract: A golf club with high accuracy in driving a golf ball is disclosed. The golf club includes a tapered hollow shaft having a thin end and a thick end, with a weight received in the hollow shaft. A head is formed with a neck that defines a stepped hole for fixedly receiving the thin end of the shaft. Importantly, the head is made less heavy than a related standard by an amount equivalent to the weight in the hollow shaft, and so the golf club has the same gross weight as a normal club.
Abstract: An electric safeguard door lock includes a lock base having an elongated plate containing an opening, two side plates each attached to the elongated plate and each containing an arcuate slot, a lock bolt pivotally mounted on a first pivot axle and having a first end detachably extending through the opening and a second end containing a slide slot, a push rod slidably received in the slide slot and having two ends each slidably received in the arcuate slot, at least one pawl member pivotally mounted on a second pivot axle and having a first end formed with a first arm containing a notch detachably receiving the push rod, and a second end formed with a second arm containing an abutting recess, a wheel including a worm gear mounted thereon, an actuating member secured on the wheel to rotate therewith and including two drive stubs each detachably abutting the abutting recess, a speed reduction motor mounted in the assembly space, and a worm mounted on the speed reduction motor and meshing with the worm gear.
Abstract: A system for determining FEXT and ELFEXT of generic cabling systems provides accurate measurements of these parameters by determining and removing the effect of the connectors at the respective ends of the link, thereby giving measurement values that correspond to the defined link, rather than including the crosstalk contributions of the connectors, which can be substantial.
Abstract: A method of soap making comprises pulverizing naturally scented flora or other material with components of the soap making process prior to saponification. An improved scented soap is thereby provided with an intensified natural scent.
Abstract: The invention provides a method of recording, and replicating a reflection hologram, which enables reference light or object light to strike on a holographic recording material at an angle of incidence that is approximate to 90.degree. or larger than the critical angle. With the reflection hologram-replicating method, the reflection hologram can be continuously replicated by allowing replicating illumination light to strike on the holographic recording material at any desired angle of incidence other than verticality. A wavefront conversion type transmission hologram 1' is located in close contact with one surface side of a reflection hologram recording material 6 while a reflection hologram plate 7 is located in close contact with the other surface side thereof.
