Title: CCD image sensor prodn. avoiding dry etching damage and thus image blurring - comprises forming 2nd conductivity type layer over 1st conductivity type semiconductor substrte, forming 1st impurity region acting as light collecting element and 2nd impurity region acting as charge transfer element etc.
Inventor: SHINJI UYA
IPC: H01L27/14
Filed: 1992-10-13
Abstract: A CCD image sensor prodn. process involves forming a second conductivity type layer over a first conductivity type semiconductor substrate, implanting first conductivity type impurity ions into the layer to form a first impurity region acting as a light collecting element and a second impurity region acting as a charge transfer element spaced from the first impurity region, forming a gate oxide film over the entire substrate surface, depositing a polysilicon film on the gate oxide film and patterning to form a gate between the first and second impurity regions. The novelty comprises (a) forming a first insulation film on the entire exposed surface after gate formation; (b) forming a second insulation film on the first insulation film and partially removing the second film to leave regions over the first and second impurity regions; (c) implanting second conductivity type impurity ions in the layer under the exposed first insulation film area to form a second conductivity type third impurity region; (d) forming a third insulation film on the entire exposed surface and removing the film portion selectively to expose the third impurity region; (e) forming a metal electrode over the third impurity region; (f) forming a fourth insulation film on the entire exposed surface; (g) removing the fourth insulation film portion above the first impurity region and then the third insulation film portion above the second impurity region for partial exposure of the second insulation film; (h) removing the exposed second insulation film portion; and (i) depositing a metal layer (64) on the entire exposed surface and removing the layer (64) selectively from above the first impurity region to form a photo-protective layer. ADVANTAGE - The process avoids damage to the substrate surface by dry etching of an insulation film portion above the light collection element and thus avoids the image blurring effect

Title: Clothes-peg
Inventor: KLEIN MANFRED
IPC: D06F95/00
Filed: 1993-08-10
Abstract: The invention relates to a clothes-peg which makes it possible to keep laundry articles together according to known principles of order, such as, for example, according to their colour, size, type or user, and which maintains this situation during the collection of dirty laundry, washing and drying and the depositing of the laundry, for example in the laundry cupboard. The object on which the invention is based is, therefore, to make the sorting and ordering of laundry articles easier in the private sector, and also in the commercial sector. For keeping together and holding simultaneously a plurality of laundry articles preferably belonging together according to known principles of order, the peg consists of a basic body having a pair of legs extending from it. Arranged between these are clamping elements which act relative to one another and which exert on the inserted laundry article a clamping force which prevents the laundry articles kept together from being separated during mechanical washing and drying. Furthermore, the basic body has means for suspending the peg.

Title: Radar-to-video-TV-standard signal converter
Inventor: HABERKAMP HERMANN
IPC: H04N5/926
Filed: 1994-02-04
Abstract: The radar signal converter consists of an encoder and a decoder. The encoder converts one or more channel radar signals into a normalised video signal. Two temporary memories have sizes matched to the radar system's data rate and have a degree of filling automatically set to the current data rate and the state of the video signal. The generated video signal contains a header line contg. time, station name, etc., and n data lines. The encoder converts the raw video signals into analog, time-transformed signals. The encoder divides the transformed signals into variable numbers of sections which are written into the data lines. A time transformation factor of the raw video signal written to the data lines is matched to the transmission system's bandwidth. The lines of the vertical sampling gap are not used for the acquisition of the raw video signals. The decoder converts the video signal back into the original radar signal.
