Abstract:
In an ink tank, there are provided a main ink chamber containing a capillary vessel member, and an intermediate ink chamber. When the ink is consumed, the ink held by capillary force of a capillary vessel member is supplied via a communication port from a joint port. The same amount of air as the amount of the consumed ink is conducted from the atmospheric communication port into the main ink chamber. The conducted ink is supplied via a groove formed in a lid to an upper surface of the capillary vessel member. As a result, the air is entered into the capillary vessel member under better condition. In a plane portion of the lid, the ink is in contact with only the capillary vessel member, and the ink remaining this portion is reduced. Thus, the ink using efficiency is increased.
Abstract:
An ink supply device for use in an ink jet printer comprising a main ink chamber in communication through a communication hole with a sub-ink chamber containing an ink absorbing member therein. A meniscus film forming member covering the communication hole and communicating the main ink chamber with the sub-ink chamber; the member having a first surface facing the interior of the main ink chamber and an opposite second surface. An ink guide member extending into a lower portion of the main chamber and also being in contact with the first surface of the film forming member, wherein as ink in the main ink chamber is consumed a differential pressure between the first and second surfaces of the film forming member causes a gradual expansion of a liquid meniscus film into an air bubble on the film forming member to maintain a constant negative pressure in the main ink chamber.
Abstract:
An air bag includes a main body formed by sewing up the respective peripheries of two fabrics, a front panel and a rear panel with a thread, first tether belts and second tether belts for connecting the central portion of the front panel and the central portion of the rear panel. Each of the first tether belts has a low strength portion structured by forming notches on both sides. Stud bolts are inserted into through holes of the first tether belts, through holes of the air bag, bolt holes of the retainer, and bolt holes of a flange. The air bag deploys to the outside of the steering wheel quite rapidly in the initial stage of the deployment, and the front panel extends suitably forward in the latter stage of the deployment.
Abstract:
In a video game apparatus, a first joystick and a second joystick each contain a stick, a game start key and a mode select key. A control circuit controls the video game apparatus in the following manner. In a one-player mode as selected, only the output signal from the joystick whose start key is operated, is supplied to the main frame of the video game apparatus. In a two-player mode as selected, the output signal from the joystick whose start key is operated is supplied to the main frame. In turn, a game is started. With the progression of the game, the output signals from the first and second joysticks are alternately applied to the main frame.
Abstract:
An electric apparatus is adapted to display a plurality of key symbols on a single passive display. A keyboard includes a plurality of input keys for selectively inputting at least numeral data and function data and input keys operated to selectively display key symbols representing numerals, functions, etc. A single passive liquid crystal display is arranged below the keyboard. A plurality of electrodes are arranged on the predetermined areas of the single passive display and the key symbols corresponding to the functions are selectively displayed, by a key operation, on the electrodes.
