An ink jet printer includes ink jet heads for recording an image on a recording medium, an ink bottle for holding ink, an ink supply path connecting the ink bottle to each ink jet head, and an electromagnetic valve provided on the path. In the printer, the bottle, the valve and the heads are arranged downward in this order in the vertical direction, the path constantly exists upwards in the vertical direction in such a manner that air entered into the path moves up above the valve due to a difference in the specific gravity between the air and the ink, the path is provided with a branching portion provided between the valve and the heads, and a sub ink tank is provided at an end of the branching portion so as to be positioned lower than the heads in the vertical direction.

This invention provides equipment for fabricating partitioning ribs of a plasma display device. The equipment comprises a head, a driver, an X position sensor and a Y position sensor, a laser displacement sensor for detecting the distance of the head from a glass plate or substrate, a motor and a motor driver for moving the head relative to the glass plate, and a CPU for controlling various circuits. The head has nozzle members for ejecting partitioning rib grains by an electrostatic ejection method or ink jet technology to form partitioning ribs. The driver controls the volume of the partitioning rib grains ejected from the head. The X and Y position sensors detect the position of the head relative to the glass plate within a plane.

A wiring board manufacturing system, which is an electric wiring forming system, utilizes a magnesium alloy as a conductive metal for wiring pattern forming, and mixes and heats the magnesium alloy chips thereof in a cylinder (feeding unit) with a built-in screw, melting same into an alloy slurry of a thixotropic state. The alloy slurry thereof is discharged onto a board. The board is mounted on a work stage of a stage unit, which is driven and controlled in accordance with wiring pattern data inputted by a CAD or the like, and a wiring pattern is formed on the board with the discharged alloy. According to this system, it is possible to provide an electric wiring forming system, which does away with the effects on the environment resulting from waste liquid at manufacturing, enables manufacturing time to be shortened, and moreover, uses an inexpensive metallic material for forming a wiring pattern.

Apparatus for data transfer with a disk cartridge having a flexible magnetic disk rotatably housed in a protective envelope with some play in its own plane. A motor driven hub has a socket defined concentrically therein, with an annular disk bearing surface formed around the socket. Rotatably mounted to a hinged clamp arm, a clamp has a tapered collet engageable in the socket in the drive hub through a central opening in the magnetic disk, and a flange on the collet for clamping an exposed annular portion of the disk against the disk bearing surface. Being loose in the protective envelope, the magnetic disk has been liable to be caught in the drive hub socket by the tapered collet which travels along an arcuate locus into engagement in the socket. In order to preclude this possibility, the disk cartridge on being loaded in the apparatus is so positioned on the drive hub that the geometrical center of the disk cartridge is offset a specified distance from the axis of rotation of the drive hub in a direction away from the fulcrum of the clamp arm.

A flexible magnetic disk drive to be mounted between, and fastened to, a pair of opposed holder plates forming parts of the housing of a data processing instrument such as a computer or word processor. The disk drive has a base structure comprising a platform, on which there are mounted such standard components as a drive drive mechanism and a head transport mechanism, and a pair of side walls on the opposite sides of the platform. Usually in the form of an aluminum die casting, the base structure would suffer deformation if it were fastened directly to the holder plates, due to positional errors between their screw holes. The deformation of the base structure is avoided by coupling the base structure to the holder plates via a pair of connectors which are fastened to the opposite side walls of the base structure. Each connector has a pair of lugs each having a hole formed therethrough for receiving screws or like fastener elements passing through holes in the holder plates. Being less in rigidity than the base structure and the holder plates, the connector lugs are deformable to take up possible positional errors between the connector lug holes and the holder plate holes.

An information processing apparatus such as a computer of the class for office and home use is disclosed which employs a magnetic disk cartridge as an information storage medium, together with a disk drive assembly for information transfer with the disk cartridge. The apparatus has a housing having defined therein a disk drive compartment, in which there is accommodated the disk drive assembly inclusive of its own enclosure having an entrance slot for the insertion of the disk cartridge. Upon full insertion of the disk drive assembly into the disk drive compartment, the disk drive assembly is locked into position by a locking lever which, under the influence of a cantilever spring, engages a first opening in the disk drive assembly. The disk drive assembly may later be disengaged from the disk drive compartment by inserting a tripping tool through the entrance slot and a second opening in the disk drive assembly and exerting a force against the locking levers opposite to the force of the cantilever spring to disengage the locking lever from the disk drive assembly, thus permitting ready withdrawal of the disk drive assembly from the disk drive compartment of the information processing apparatus as for maintenance purposes.
