  • Patent number: 8224328
    Abstract: Disclosed is a mobile communication system which includes user equipment, radio base stations which communicate with the user equipment, and an upper level apparatus which communicates with the radio base stations. Each of the radio base stations includes a control unit and an inter-node communication unit. The control unit hands over a communication with user equipment to a hand-over target base station. The control unit prepares a forwarding packet which includes data addressed to the user equipment and is not transmitted and delay value identification information for specifying a delay value of the data that is not transmitted at the time of a hand-over. The inter-node communication unit transmits forwarding packets to a hand-over target base station.

  • Patent number: 7745307
    Abstract: In a method of manufacturing an inkjet head, a silicon dioxide (SiO2) layer is produced on the surface of first silicon member formed from single-crystal silicon. Next, a glass layer formed of borosilicate glass or the like is sputtered onto the surface of the silicon dioxide (SiO2) layer. A silicon oxide (SiOx, x<2) layer is then formed on the surface of a second silicon member. The first and second silicon members and are bonded together by applying heat at about 450° C. with heaters, as a DC voltage is applied across electrode terminals. As a result, a silicon dioxide (SiO2) layer is formed at the interface of the glass layer and silicon oxide (SiOx, x<2) layer, anodically bonding the two layers.

  • Patent number: 6918180
    Abstract: To adhere an actuator unit onto one surface of a diaphragm, a dipping plate is used to evenly cling an adhesive agent to tip ends of a plurality of actuators formed in the actuator unit. The dipping plate is formed with a plurality of grooves corresponding to the respective ones of the plurality of actuators. An adhesive agent is poured into the grooves to the same level and the actuators are dipped into the adhesive pond while maintaining a state in which an imaginary first line that connects the tip ends of said plurality of actuators is in parallel with an imaginary second line that connects borders between immersed and non-immersed portions of the plurality of actuators. The actuators are drawn from the adhesive ponds and adhered to one surface of the diaphragm. An ink channel unit is connected to the opposite surface of the diagram.

  • Patent number: 6843554
    Abstract: An ink jet head including nozzles, ink chambers, and an ink channel in fluid communication with each other. A diaphragm defines one portion of each of the ink chambers. Piezoelectric actuators are disposed in confrontation with the diaphragm in a one-to-one correspondence with the ink chambers. A relay member is provided between each piezoelectric actuator and the diaphragm. Each relay member has a first abutment surface and a second abutment surface on opposite sides thereof. Each first abutment surface abuts the diaphragm across a width that extends in the nozzle alignment direction. The width of each first abutment surface is shorter than the width of the corresponding ink chamber. Each second abutment surface is coupled to the corresponding piezoelectric actuator and has a width that extends in the nozzle alignment direction. The width of each second abutment surface is equal to or shorter than the width of the corresponding piezoelectric actuator.
