Title: Method for improving the reliability of multicasting
Inventor: LUO JIUN-HAU
IPC: H04L29/06
Filed: 1999-04-06
Granted: 2000-09-21
Abstract: The invention uses a range value set in the packet deadline frame to improve the reliability of multicasting.  In packet transmission, a range value is preset to indicate the transmission range of the packet. Once the packet passes a router of a sub-network, the range value decreases until the value equals to unity. Once the packet is lost, the range value of the packet is set to ""1"" to search the group member responsible for re-sending the packet in the same sub-network. If the member responses, the transmitting packet can be received directly without being re-sent from the sender. If the search fails, the range value increases by 1, to search in another sub-network until the waiting time of the packet is reached.

Title: Ratchet and cam buckle tensioning assembly and method for using same
Inventor: LANDY RICHARD
IPC: B60P7/08
Filed: 1999-05-29
Granted: 2000-05-21
Abstract: A ratchet and cam buckle tensioning assembly or strap tensioner, interposed between a lashing strap tensioned by the ratchet buckle and a lead strap tensioned by the cam buckle. The invention enables an operator to quickly and conveniently pre-tension the lashing and lead straps by removing an un-tensioned length of the lead strap without having to operate the ratchet buckle. The tensioning assembly includes a ratchet buckle for tensioning the lashing strap in stepped increments and a cam buckle for slidingly adjusting the lead strap. The cam buckle housing and the ratchet buckle frame member are a unitary member, forming an single, integrated tensioning assembly. Alternately, the cam buckle is permanently attached adjacent to the ratchet buckle. The cam buckle includes a housing adapted to slidably receive the lead strap. The housing has a pressure plate with a first restraining surface, such as a friction surface, over which the lead strap slides. A pawl is movably mounted, such as by pivoting, to the housing. The pawl has a second restraining surface and is biased in an engaged position to restrain the lead strap between the first and second restraining surfaces so as to prevent movement of the lead strap in one or both directions. The pawl also may assume a disengaged position wherein the lead strap can move freely between the first and second restraining surfaces.

Granted: 2001-08-11
Abstract: A power locking mechanism provides a structure for supporting a physically manipulable lock, and is in communication with a permanently installed switching connector fitting within the confines of an alternating current power socket typically found at the rear of a personal computer. The switching connector has a male portion which becomes a male locking portion with the addition of a locking clip member which positively engages the alternating current socket of a computer, an intermediate portion containing circuitry to insure proper switched on and off operation, and a female socket portion for interfitting with the end of the power cord which was previously used to connect into the alternating power socket. As such, installation of the device of the invention involves removing the power cord computer plug from the computer's power input socket, inserting the male portion of the switching connector into the socket and inserting the power cord plug into the female portion of the switching connector of the invention. Locking is achieved with a flared engagement member which fits into an identation on the male portion of the switching connector. The clip member of one embodiment is removable in order that the switching connector be tested in place, before insertion to commit to permanent connect status.

Title: Method for controlling Si melt liquid and growth method of crystal
Inventor: AZAMI TAKESHI
IPC: C30B15/20
Filed: 2000-03-24
Granted: 2003-08-21
Abstract: Keep controlling the irregular variation of temperature in the melt liquid so as to prevent the homogenization of crystal growth from being interfered. In the FZ method, the partial pressure of such as oxygen in the composition of atmosphere ambient to the melt liquids may increase particularly to 1.8 E (-5) MPa or higher by controlling the partial pressure of oxygen. This results the vibration of temperature in the melt liquids becoming single period and thus that there is no turbulence of vibration of temperature and crystal with high homogenization can be grown up. Further, in the CZ method, the partial pressure of such as oxygen in the composition of atmosphere ambient to the melt liquids may also change partial oxygen pressure on surface into high pressure by controlling the partial pressure of oxygen. This results that the Maragoni convection strength on the surface of melt liquids is reduced and the vibration of temperature in the melt liquids becomes single period. Thus there is not only no turbulence of vibration of temperature but also the oxygen concentration of crystal being controlled and crystal with high homogenization can be grew up.

Title: Electric motor having an armature with a coil winding pattern and method for winding an armature of an electric motor
Inventor: WANG REN-HONG
IPC: H02K23/30
Filed: 2000-10-13
Granted: 2002-06-11
Abstract: An armature for a brush commutated electric motor having a distributed coil winding arrangement for reducing brush arcing and electro-magnetic interference (EMI). The winding pattern involves segmenting each coil into first and second subcoil portions with differing pluralities of turns. Each subcoil portion is wound around separate pairs of spaced apart slots of a lamination stack. Adjacent coils are wound such that one subcoil portion of each is wound in a common slot to therefore form an overlapping arrangement of each pair of adjacently coils. The winding pattern serves to ""shift"" the resultant magnetic axes of each coil in such a manner so as to significantly reduce brush arcing and the EMI resulting therefrom. The reduction in EMI is sufficient to eliminate the need for EMI reducing components, such as chokes, which have typically been required to maintain EMI to acceptably low levels. Commutation efficiency is also improved by the distributed winding pattern described above because of the reduction in the unevenness of the magnetic coupling between adjacent coils.

Abstract: A light-emitting device having the quality of an image high in homogeneity is provided. A printed wiring board (second substrate) (107) is provided facing a substrate (first substrate)(101) that has a luminous element (102) formed thereon. A PWB side wiring (second group of wirings) (110) on the printed wiring board (107) is electrically connected to element side wirings (first group of wirings) (103, 104) by anisotropic conductive films (105a, 105b).
