摘要： An ink-jet head includes pressure chambers arranged in a row in a row-direction, and a manifold flow passage communicated with the pressure chambers and extending in the row-direction. An ink inflow port is formed at one end of the manifold flow passage. The manifold flow passage has a main portion, a connecting portion, and an extended portion which are arranged in this order from a side close to the ink inflow port. The manifold flow passage is communicated with the pressure chambers at the main portion. The main portion has a constant cross-sectional area greater than that of the connecting portion. A cross-sectional area of the extended portion is greater than that of the connecting portion. The pressure wave, generated in the pressure chamber and propagated to the manifold flow passage, can be efficiently attenuated by the manifold flow passage constructed as described above.

摘要： A droplet-jetting device, which is usable for an ink-jet recording apparatus, comprises a pressure chamber disposed between a cavity plate and a pressure-generating section of a piezoelectric actuator. The pressure-generating section and the cavity plate are connected by a connecting section. When a voltage is applied to the piezoelectric actuator, the pressure-generating section is elongated to depress the bottom of the pressure chamber downwardly so that the volume of the pressure chamber is increased. The droplet-jetting device is realized, in which the area of arrangement of the pressure-generating section is decreased to suppress the electrostatic capacity and the pull-eject can be performed by applying the voltage only when the device is driven.

摘要： A pulse modulator generates a first pulse signal having a duty ratio which is adjusted such that a detection voltage which indicates the electrical state of an LED string to be driven matches a predetermined reference voltage. A first pulse signal is applied to a primary coil of a pulse transformer. A DC/DC converter includes a switching element the ON/OFF operation of which is controlled according to a signal that originates at a secondary coil of the pulse transformer. The DC/DC converter stabilizes an input voltage Vdc, and supplies the input voltage Vdc thus stabilized to the anode of the LED string.

摘要： A hydrogen electrolysis apparatus includes a stack of unit cells each having a membrane electrode assembly sandwiched between an anode separator and a cathode separator. The anode separator has a first flow field which is supplied with water, and the cathode separator has a second flow field which produces high-pressure hydrogen through an electrolysis of the water. The cathode separator also has a first seal groove defined therein which extends around the second flow field and a first seal member inserted in the first seal groove. The first seal groove and the second flow field are held in fluid communication with each other through passageways. The passageways keep the first seal groove and the second flow field in direct fluid communication with each other in bypassing relation to the boundary between the cathode separator and a solid polymer electrolyte membrane.

摘要： In a liquid ejection apparatus, common liquid chambers adjacent to each other and connection passages extending from the adjacent common liquid chambers are separated by a partition wall. The partition wall has a first side surface and a second side surface opposite the first side surface. The first side surface define one of side surfaces of the common chamber and one of side surfaces of the connection passage extending from the common chamber. The second side surface defines one of side surfaces of the other common chamber and one of side surfaces of the other connection passage extending from the other common chamber. The partition wall has a curved surface connecting the first side surface to the second side surface in a vicinity of a position where the connection passages having the partition wall placed therebetween are connected to each other. A curvature of the curved surface is larger than a curvature of an arc having a diameter equal to a width of the partition wall.
