Abstract: A device includes a rear holding member including a front externally threaded projection and a varied-diameter passage; a flexible clamping member including a conic section, a rear tapered section, and an axial channel; a retainer ring including an inwardly extending annular member and an internally threaded section; a front holding member including a rear flange, a front conic passageway, and internal threads; and a fastening ring including rear threads, an internal shoulder, and two front, opposite curved members. The clamping member is urged against the passage; the retaining ring is put on the rear holding member; a drill bill is configured to insert through the channel into the passage; the front holding member has a rear end urging against the annular member; the internal threads are secured to the externally threaded projection, and an inner surface of the front holding member compresses the conic section.

Abstract: The present invention relates to a window shutter apparatus and architectural optical assemblies thereof. The architectural optical assembly includes a discolorable element and a light-shielding element. The discolorable element is used for receiving the light beam to exhibit discoloration effect. The light-shielding element is disposed adjacent to the discolorable element and used for shielding a part of the light beam having a wavelength within a predetermined range. Thereby, the architectural optical assembly has both light-shielding effect and light-transmitting effect. Furthermore, the architectural optical assembly can be applied to a window shutter apparatus. Whereby, the window shutter apparatus has both light-shielding effect and light-transmitting effect.

Abstract: A computer controlled system and method of using the system for control of shipping a quantity of product either domestically or internationally. The system comprises a number of user input stations for entering a shipping request. Product release information stored in the computer is added to the request which is transmitted t a product storage unit, a printer, and an exit control station. The product storage unit selects the product requested. The printer prints a product release form which can include a customs declaration form and/or a digital authentication stamp if desired. The product is prepared for shipping and the product release form is attached. The product and the product release form is checked at the exit control station. The product is then shipped or corrective action is taken.

A set of reduction gears are disposed between and engageable with the follower gear on the shaft of the lens and the driving gear on the drive spindle of the motor. By means of the rotation of the motor, the lens is rotatable horizontally, while the digital camera remains stationary, to a desired direction in order to take a picture.

Abstract: An aperture selection mechanism for camera lens includes an aperture strip and a disk selection knob. The aperture strip has two or more different sizes of apertures equally spaced from each other and being sequenced by size. Turning the selection knob, the aperture strip will be moved and one of the apertures will be positioned in the light path of the camera lens. Two or more apertures may be moved to the light path of camera lens one at a time so that the camera can produce better quality of photo and image. The structure is simple, low cost and easy to use.
