Patent EP-0073672-A2 (EP)
Inventor: CREAN PETER AIDAN
IPC: B41J2/12
Filed: 1982-08-27
Abstract: An ink jet marking array for enhancing ink droplet placing accuracy which combines a bipolar scanning arrangement with a drop interlace scheme. The marking apparatus comprises an array of ink jef column generators (12) which direct ink droplets (24) to first a charging region (28) and then through a deflection region (26). The droplets are charged either negatively or positively depending on a desired droplet trajectory; thus the bipolar designation. The deflection region has an electric flield strength slightly less than the breakdown field strength of air for the environment in which the apparatus is to operate. The high field strength reduces the charge which must be applied to the droplets (24) and therefore minimizes the drop to drop coulomb interaction. The interlace strategy causes sequential drops from a given generator to be printed in non-sequential locations on the paper. This strategy spreads out the ink droplets (24) in space and results in a reduction of both aerodynamic and coulombic interaction between droplets. By reducing these interactions and minimizing the time of flight for the drops the placement accuracy is increased. The placement accuracy is further enhanced by utilizing a charging scheme which takes into account the charge induced on other droplets in close proximity of the droplet to correct for coulomb interactions even the bilopar plus interlace strategy cannot avoid.

Abstract: A self-refreshing non-volatile memory cell having two cross-coupled transistors includes a first floating gate formed between the gate and the channel of said first transistor, said first floating gate overlying by means of a tunnel oxide a portion of the drain of said second transistor and a second floating gate formed between the gate and channel of said second transistor, a portion of said second floating gate overlying by tunnel oxide a portion of the drain of the first transistor. Disturbances in the supply voltage and the gate voltage of the device normally enhance rather than degrade the state of data stored in the cell, thereby providing an extremely long storage time for the cell. The cell is capable of operating simultaneously in a volatile and a non-volatile state.

Abstract: τhis invention is a process for fabricating optical devices by photoetching geometrical shapes on the surface of an n-type or intrinsic compound semiconductor so as to yield surfaces of optical quality without further processing. The etching process is an electrochemical process where etching is proportional to light intensity. The process involves applying a potential to the compound semiconductor while immersed in an electrolytic solution containing hydrofluoric acid and irradiating the surface to be etched with light in a certain energy range. The distribution of light intensity and ray direction is selected to produce the desired geometrical shape. Particularly advantageous is that the surfaces produced are of optical quality. For example, lenses produced by the etching process exhibit surfaces of optical quality. Further, the process can be carried out on all the lenses on a wafer simultaneously without attention to individual devices. This is highly desirable economically. Also, the lenses produced are integral parts of the light emitting diode.

Abstract: A divisible hard gelatine capsule, particularly for solid or highly-viscous flowable products, consists of two halves which represent opposing semi-circles in cross-section, each with a respective bottom part and a top part which is attached thereto. The sum of the two thicknesses of the capsule halves is somewhat less than the width thereof and the two opposing semi-circular capsule halves are joined approximately in the centre, with respect to the longitudinal axis, so that the divisible capsule can be divided into two parts by twisting them substantially about a transverse axis perpendicular to the opposed planar walls of the capsule halves. The invention further relates to a process for producing the filled divisible hard gelatine capsule.

Abstract: @ A camshaft is prepared from separately formed cams (10) and a shaft (19). The cams (10) may for example be formed by sintering. The cams are provided with holes (12) which are under-sized and are provided with serrations (13). They are located on a correspondingly shaped dummy shaft (14) in their required relative orientations and angular positions. Next, the cams (10) are clamped in these positions and the dummy shaft (14) removed. The cams are then heated to red heat and the serrated holes in them broached to bring them to their final size and to concentricity. Finally, a shaft (19) having an exterior profile corresponding to the shape and size of the broached profile of the holes (12), at ambient temperature, is introduced into the holes and the cams are then cooled so that they shrink fit on to the shaft so ensuring that they are accurately positioned on the shaft. The cams are then released from the jig to give a finished camshaft.

Abstract: In a process for adapting the air flow in the heating zone and/or the cooling zone of a tunnel furnace in the ceramic industry with changing charge, to change the set values for the temperature in the zone to be regulated, a first set value assigned to the first charge type has added to it a component which is evaluated with a factor, which results from the difference between the first set value and the second set value, which is assigned to the charge type following, the set values being determined empirically. As a result, a regulating process is produced, by means of which a satisfactory adaptation of the air flow in the heating zone and/or the cooling zone of a tunnel furnace can be brought about rapidly, even with changing charge.
