Patent number: 6830388Abstract: A camera rotation device comprises motors provided on rotated sides rotating with a camera with respect to their rotating sides which rotate the camera. More specifically, regarding a pan direction, a pan motor is provided in a pan section which rotates with respect to a base section. With regard to a tilt direction, a tilt motor is provided in a tilt section which rotates with respect to the pan section. Torque of each motor is transferred to each rotating side so that the camera on the rotated side rotates with the motor by reaction force of the rotating side. This structure, in comparison with conventional devices where a motor and a rotation mechanism are provided separately, has a motor provided on the rotated side and therefore reduces space for mounting a motor. As a result, this configuration enables the camera rotation device to be made smaller.Type: GrantFiled: July 3, 2003Date of Patent: December 14, 2004Assignees: Matsushita Electric Industrial Co., Ltd., Nanshin Chemical Industry Co., LtdInventors: Tetsurou Kajino, Shouichi Tada

Patent number: 6830396Abstract: A system for configuring keyboards using both frequency and alphabetical bases. The Keyboard Configuration System uses alphabetized frequency-based sets of keys in rows in order to fulfill the requirement that the keyboard must provide a key for each letter of the alphabet. The alphabet is analyzed for letter use on a frequency basis. The frequency-ranked list is then broken into rows according to the number of rows needed for the keyboard. Each row resulting from the frequency-ranked list is then alphabetized independently so that each resulting key row represents a certain segment of the frequency-ranked list. Each key row is alphabetized separately. Each key row may be of different length and the resulting keyboard may have a number of configurations depending upon the relative shift between each of the independently arranged key rows. Generally, the longest key row determines the number of key row shifts, or cases, as left or right justification rules generally apply.Type: GrantFiled: March 31, 2003Date of Patent: December 14, 2004Inventor: Francis N.

Patent number: 6830411Abstract: A method of making artificial barrier islands or break waters. The method consists of driving a series of piles in the shape of the island, attaching a number of wire mesh sections, to form a fence around the perimeter of the piles, connecting the tops of the piles with cables, and then filling the formed enclosure with riprap (rock) material. Once the rock has reached the water surface, it is covered with suitable soil and vegetation to create the island. The piles and mesh are hidden below the water surface and the formed island takes on a natural appearance. In this way, the artificial island is a barrier to storms, thus protecting the shoreline and wetlands from erosion. Moreover, the artificial island creates an ideal habitat for birds, fish, reptiles and amphibians. In certain environments one island can protect approximately 10 times the amount of shoreline that lies behind it.Type: GrantFiled: November 18, 2003Date of Patent: December 14, 2004Inventor: Dominick Amari

Patent number: 6830423Abstract: A personal mobility vehicle (PMV) lift for loading and offloading a personal mobility vehicle (PMV) into and from a rear portion of a vehicle, the vehicle having an interior floor and a trailer hitch rigidly attached to the rear of the vehicle to which the PMV lift is rigidly engageable. The PMV lift receives substantially all of its support from the trailer hitch and includes an elongated laterally extending lifting boom and a drive mechanism connected adjacent a proximal end thereof. The drive mechanism includes an elongated flexible lifting cable or belt which is operably connectable for raising and lowering the PMV by operation of the drive mechanism. An upright stanchion is supportively connected to the lifting boom while an elongated lift support arm is supportively connected to a lower end of the stanchion. A trailer hitch engaging member is connectable at one end to the trailer hitch, the other end of which is connected to a proximal end of the lift support arm.Type: GrantFiled: December 18, 2002Date of Patent: December 14, 2004Assignee: Chadco Enterprises, Inc.Inventors: Chad Williams, Jeff DuVal

Patent number: 6830426Abstract: A set of seals is installed on the impeller of a centrifugal pump that allows a low viscosity fluid to be injected into a chamber between the impeller shroud and the casing sidewall. A seal ring, with a number of grooves formed in it is installed on the tip of the impeller. Another seal ring is mounted at the leading edge of the eye of the impeller. The gas is picked up by the grooves in the impeller tip ring inside diameter and is compressed by centrifugal force to a higher pressure than the discharge pressure of the impeller. It is then injected into the pumpage stream. The eye ring seals have pockets or grooves and inject gas at a low volume into the eye of the impeller.Type: GrantFiled: July 11, 2002Date of Patent: December 14, 2004Inventor: David T. Stilcs

Patent number: 6830427Abstract: A high-pressure turbine nozzle-vane band for a gas turbine engine. The band includes an inside surface supporting at least one guide vane having a trailing edge that is directed towards a downstream end of the band, and an outside surface, opposite the inside surface, from which a flange extends radially, defining firstly, upstream from the flange, a passage for cooling-air, and secondly, downstream from the flange, a cavity. The inside surface of the band is provided, between the trailing edge of the guide vane and the downstream end of the band, with a coating forming a thermal barrier enabling a temperature gradient generated in the band by the air spinning in the cavity to be increased.Type: GrantFiled: November 26, 2002Date of Patent: December 14, 2004Assignee: Snecma MoteursInventors: Grégory Lafarge, Christophe Texier

Patent number: 6830429Abstract: A small cooling fan includes a rotating fan body with a vane in a flat fan housing, and an air channel for backflow prevention. The air channel is provided outside of the vicinity of the tip of the vane of the rotating fan body, extends to an air outlet, and has an inner height larger than that of a fan chamber. This structure can prevent the backflow of the wind at the air outlet and reduce the loss of the static pressure, thereby increasing the airflow quantity in spite of the small size.Type: GrantFiled: August 21, 2002Date of Patent: December 14, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Masahiko Hirata

Patent number: 6830432Abstract: A turbine fluid guide member (10) including an airfoil portion (12), a platform portion (14) and fillet (16) joining the airfoil portion to the platform portion. Fillet cooling holes (18a-18f) are positioned in the turbine fluid guide member relative to a pressure side vortex flow (22) so that a cooling fluid flow (20) exiting the hole is directed to form a cooling film (32) over the fillet. The cooling holes may be positioned in the airfoil portion, the platform portion, or any combination thereof, depending on the geometry of the airfoil and resultant vortex flows around the airfoil. A method of cooling a fillet of the turbine fluid guide member may include identifying a vortex flow around the fillet and selectively positioning a hole relative to the vortex flow such that a cooling fluid flow exiting the hole is directed to form a cooling film over the fillet.Type: GrantFiled: June 24, 2003Date of Patent: December 14, 2004Assignee: Siemens Westinghouse Power CorporationInventors: Robert Kenmer Scott, Joseph Theodore Tapley
