Abstract: ABSTRACT:           A colour filter having filter elements res-pectively passing light of the colours red (R), green (G) and blue (B) is provided on a semiconductor image sensor which comprises a system of photosensitive ele-ments. The filter elements are separated by grooves which prevent the running of dye liqiud during dyeing the various systems of filter elements and hence the occurrence of colour defects. Instead of grooves the filter elements may also be separated by regions which have been converted into a structure which is substan-tially impervious to liquid. The colour filters may also be used in a cathode-ray tube for imaging colour pictures.

Abstract: MANUFACTURE OF ELECTRODES WITH LEAD BASE             Abstract An electrode having a lead base and a catalyst is manufactured by (a) compressing titanium sponge particles so as to consolidate them to a coherent porous layer, (b) applying the catalyst to the titanium sponge particles, and (c) fixing the layer of consolidated sponge particles to the lead base. The catalyst is formed on the titanium sponge particles before or after their consolidation to a coherent layer. This layer may be produced and fixed to the base in a single compressing and fixing step combining (a) and (c). Oxygen is anodically evolved at a reduced, stable potential by means of this electrode, so that it can be usefully applied as an anode in processes for electrowinning metals from acid electrolytes.

Abstract: ABSTRACT OF THE DISCLOSURE       A locking and unlocking device particularly employable for a double lock system comprising a bank lock and a client lock is disclosed.  To operate the bank lock a magnetic card specifically allocated to a client is inserted into a casing or cover through a card insert hole until a plurality of magnetized points on the magnetic card are located in alignment with the corresponding permanent magnet pins which are held in engagement holes on a sliding member or lever.  Polarities and coordinate positions of the magnetized points on the magnetic card are previously determined by means of an encoder.  The permanent magnet pins are brought in disengagement from the engagement holes under the influence of magnetic repulsive or attractive force developed between the permanent magnet pins and the magnetized points on the magnetic card when the latter is inserted through the card insert hole.  After the sliding member or lever is free from the permanent magnet pins, it is displaced in such a direction that a window formed on the bottom of the casing or the base member becomes exposed to the outside and thereafter the client inserts his key through the window to open the client lock.  The cover is slidably fitted to the base member and after the magnetic card is inserted, it is displaced in the opposite direction to that of insertion of the magnetic card.  Safe room entering and leaving readers are preferably fitted to an automatic door for the rental safe room.

Abstract: Abstract Disclosed is a method and a means for creating a visual display of data from an input data set in which the data are not fixed into display-acceptable format until the data are stored in a local memory of the visual display.  At least one of a plurality of sources of resource information is initially selected as required by the input data set.  Control signals corresponding to the sources of resource information are thereafter embedded into the input data set to form an output data set.  Subsequently, the selected sources of resource information and the output data set are applied to the local memory.  They are concurrently taken from this local memory to produce a visual display.  Fixation of the data into display acceptable format is thereby postponed until just prior to actual display to thereby provide a substantial increase in system flexibility.
