Abstract: A bicycle derailleur comprises a mounting member adapted to be mounted to a bicycle frame, a base member pivotably mounted relative to the mounting member, a biasing mechanism that biases the base member clockwise relative to the mounting member when viewed laterally outwardly from the base member, a chain guide and a coupling mechanism coupled between the base member and the chain guide so that the chain guide moves relative to the base member. A rotation restricting mechanism is disposed in a force communicating path between the mounting member and the base member to restrict counterclockwise rotation of the base member relative to the mounting member.

Abstract: A head unit is inverted so that an outflow port is in the lowest position. Because the top wall of the buffer tank slopes downwards towards the outflow port, all remaining cleaning fluid that was introduced during manufacture is removed. Also, a notch is provided in the bottom end of an ink introduction port. The notch faces towards the outflow port so that bubbles in the ink exit from the notch and are guided towards the outflow port. The head unit is shipped while the buffer tank is filled with preservation fluid that has high wettability and any openings to the outside air are closed off with covers. When the head unit is used, the preservation fluid is sucked by a purging device and then ink, which has a high affinity for the preservation fluid, is smoothly introduced. Also, the inner surface of the filters are treated to increase the wettability by ink after the filters are fixed to the bottom lid. Afterwards the bottom lid is fixed to the top lid to form the buffer tank.

Abstract: In an ink-jet printer, a support member includes a wiper cleaning zone provided upstream of a wiping direction of a nozzle surface. The wiper cleaning zone includes a cleaning wall, a first surface, and a plurality of grooves. The cleaning wall protrudes from the support member. The first surface extends in a direction reverse to the wiping direction, continuously from the cleaning wall. The plurality of grooves are provided in the first surface, extending from the cleaning wall. The grooves are formed at a predetermined distance from each other and hold ink therein by capillary action. Ink, adhered to a wiper by wiping operation, is rubbed by the cleaning wall provided in the wiper cleaning zone, and the collected ink is held by the grooves continuously formed from the cleaning wall. A similar, but reversed, structure is found on the other side of the nozzle surface in the wiping direction.

Abstract: A rotary blade cuts a photosensitive/pressure-sensitive recording medium by when slides in a widthwise direction of the recording medium. At this time, one terminal of an optical fiber moves ahead of the rotary blade while radiating an optical beam on a portion of the recording medium, so that microcapsules of the recording medium in the exposed portion are all hardened by react to the optical beam. Therefore, mechanical stress generated by the rotary blade does not rupture the microcapsules.

Abstract: A rotary magnetic head apparatus according to one aspect of the invention has magnetic heads mounted on a rotary drum, a rotor which rotates together with the rotary drum and a circuit board with electronic circuits formed thereon provided between the rotor and the magnetic heads. While a connecting device according to another aspect of the invention has at least one spring contact and outer lead terminals extending in at least three directions and a resin mold body for fixing them together in a body, and the lead terminal extending in one direction is electrically connected with the spring contact while the remaining two terminals extending in other directions are electrically connected to each other in the resin mold body.

Abstract: In the machine of this invention, a rotation-support member is provided in an outer tub for containing water so that the rotation-support member can rotate about a vertical axis. The rotation-support member supports a perforated inner tub rotatable about a horizontal axis. A heating means heats air in the inner tub. When the laundry is washed or rinsed, the laundry is loaded in the inner tub, water is supplied to the outer tub until the water reaches inside the inner tub, and the inner tub is rotated about the horizontal axis. The laundry is prevented from jumping out of the inner tub during the washing and rinsing process due to boards or net provided in the inner tub. When the washed or rinsed laundry is dehydrated, water is drained from the outer tub, the rotation-support member and the inner tub are rotated together about the vertical axis in the same direction at the same high speed.
