Title: System and method for gsm hard handoff
Inventor: RIMONI YORAM
IPC: H04B1/707
Filed: 2004-06-18
Abstract: A GSM1x (206)-to-GSM (208) handoff feature allows a GSM1x subscriber with a dual-mode (GSM1x and GSM modes) handset (204) to seamlessly roam from GSM1x coverage areas to GSM coverage areas. This functionality is facilitated by the GSM1x system design which integrates a CDMA RAN with a standard GSM core network. The GSM1x system is built using standard CDMA as its air interface and an unmodified CDMA RAN with a standard IOS interface to the MSN (304). The only modifications are done at the MSN (304) and the MS.
Patent CA-2531074-A1 (CA)
Inventor: FENG XIAOGEN
IPC: C07C211/55
Filed: 2004-07-02
Abstract: The present invention discloses a method for producing 4-aminodiphenylamine by reacting nitrobenzene with an aniline in the presence of complex base catalyst for condensation and complex powdery catalyst for hydrogenation, which comprises the steps of condensation, separation, hydrogenation, separation II and refining sequentially. The method of the present invention can be carried out continuously.  By using the complex base catalyst for the condensation, followed being separated and recycling before the hydrogenation, the problem of heat-sensitive decomposition of the complex base catalyst during the hydrogenation procedure can be avoided.  Accordingly, the choice of the hydrogenation catalyst is increased, and lower-cost hydrogenation catalysts can be used. Meanwhile, the apparatus can be selected easily and the industrializaion can be achieved simply. The complex base catalyst according to the invention is cheaper. The catalytic activity of the catalyst is high and the condition of the reaction is gentle. Additionally, the complex base catalyst is suitable to a wide range of water content. Accordingly, the amount of the by-product is decreased, and the conversion and the selectivity can be increased. The labour intensity of the process control is low. Moreover, corrodible liquid is not generated and the environmental pollution can be reduced. The content of 4-aminodiphenylamine reaches 99% (by weight), and yield in the industrial-scale production is greater than 95%.

Filed: 2005-06-06
Abstract: An inkjet printing apparatus includes a mechanism for opening and closing an ink supply route between an ink tank and a printing head and capable of attaching and removing the ink tank by a horizontal movement. More specifically, a moving member 60 and the communication pipe 51 engaged therewith are moved upward by moving an operation member 70 upward. As a result, the communication pipe 51 moves into an ink lead chamber 16 and a communication channel 52 of the communication pipe 51 comes into communication with the ink lead chamber 16 through its opening. In this way, the ink lead chamber 16, namely, an ink storage chamber 12 comes into communication with a liquid chamber 50 of a printing head 20. An ink supply route is opened in this manner. The ink supply route is closed by the reverse operation to that mentioned above.
