Abstract: Process for the preparation of solid photoactivator formulations Abstract of the Disclosure The invention relates to a process for the preparation of solid photoactivator formulations containing sulfonated zinc or aluminium phthalocyanines. The process comprises passing a crude solution containing these compounds through a semipermeable asymmetrical membrane having a pore diameter of 1 to 500 .ANG. and drying the photoactivator solution obtained under mild conditions. The membrane consists of a basic structure of cellulose acetate, polyacrylo-nitrile or a copolymer of acrylonitrile and other ethylenically unsaturated monomers. This basic structure is modified in specific manner with ionic groups. If desired, fillers and/or surfactants customarily employed in the detergent industry may be added to the concentrated solution before it is dried.            The solid photoactivator formulations so obtained have excellent storage stability, are substantially non-hygroscopic, and contain exceedingly small amounts of undesirable organic impurities.

Abstract: Abstract This invention relates to a process for preparing a semiconductor device comprising the steps of depositing a photosensitive material on a substrate, irradiating the photosensitive material in a desired pattern, developing the pattern and completing the fabrication of the device.          The photosensitive material that is sensitive to ultraviolet radiation and that exhibits excellent contrast is formed from base soluble polymers such as poly(methyl methacrylate-co-methacrylic acid) physically mixed with base insoluble materials such as o,o'-dinitrobenzyl esters.         The base insoluble esters decompose upon irradiation to form base soluble entities in the irradiated regions.          These irradiated portions are then soluble in basic solutions that are used to develop the desired image.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention provides an efficient process for the catalytic hydrogenation reforming of a heavy oil, in which the slurry of a feed heavy oil and catalyst particles is introduced into a reaction vessel and ascends in the vessel as being carried by the hydrogen-containing gas introduced into the vessel at the bottom.  When the slurry reached the upper part of the vessel, the slurry is freed from the gaseous material and then descends in the vessel through a gravity-difference separation zone formed in contact with the inner walls of the vessel, in which the descending velocity of the slurry is so low that the catalyst particles gravitationally settle in the slurry and are separated from the liquid portion and the liquid portion thus freed from the catalyst particles is discharged through the liquid discharge port provided at the side wall of the vessel at such a space velocity as not to disturb free settling of the catalyst particles in the separation zone.  The slurry containing the thus increased amount of the catalyst parti-cles descends to the bottom of the vessel and is again carried up by the gas through the upflow zone formed in the central portion of the vessel.

Abstract: ABSTRACT OF THE DISCLOSURE     In order to achieve in multilayer foils a speedy and uniform heating without unduly influencing temperature-sensitve inner layers the heating proceeds in two steps.  The first step is made in a contact heating apparatus and the second in a radiation heating apparatus.          The punching out of the articles shaped in a forming station proceeds also in two steps.  Initially a pre-punching apparatus produces a pre-punching leaving pre-determined breaking lines.  In a following periphery punching apparatus the articles are firstly centered and thereafter punched to their definite shape.  This allows that during the punching any mistakes due to the shrinking of the foil having cooled can be decreased or  even eliminated.  The transport of the web through the entire apparatus proceeds by means of a plurality of driving wheels  located at both sides of the web feeding path.

Abstract: OPTICAL RECORDING BY ENERGY-INDUCED FRACTIONATION     AND HOMOGENIZATION           Abstract of the Disclosure A method of and structure for optical recording by energy-induced  homogenization  or  fractionation is disclosed.  When the method involves fractionation, a film is provided that contains a homogeneous mixture of a matrix material  and  an incident energy absorbing material. A spot on the film is treated with sufficient energy in the form of electric fields, radiation or heat, or combinations thereof to effect fractionation and/or homogenization of the film which will undergo further physical state transition only under treatment with additional energy.  In a preferred embodiment,  the fractionation is effected by laser radiation. The laser irradiated spot becomes inhomogeneous  and can be detected by the resulting changes in its optical properties.  When the method involves homogenization, a film is provided that contains a inhomogeneous mixture. The energy treated spot in this case becomes homogeneous without undergoing a phase  transition between the amorphous and crystalline phases. Numerous combinations of fractionation and homogenization can result in the writing and erasing of information in a storage device.

Abstract: Abstract of the Disclosure A cordless telephone includes a base unit and a handset unit.  When the handset unit is mounted on -the base unit, an identifying code is automatically generated and stored in both units.  Thereafter, when an incoming or outgoing telephone call is initiated, the two stored identi-fying codes are compared, and the telephone call proceeds only if the two identifying codes are identical.  The new identifying code is generated as a counted value in accor-dance with a predetermined time following the mounting of the handset unit on the base unit.  By having the prede-termined time vary  from telephone to telephone, the identi-fying codes will also vary, eliminating crosstalk interfer-ence and the risk of wiretapping.

Abstract: ABSTRACT OF THE DISCLOSURE:         A feed gas is partially burnt with oxygen-containing gas in a thermal Claus process plant, in which temperatures in the range of 850 to 1350°C is maintained.  Product gas which has been produced is passed through a catalytic Claus process plant (Claus catalysis plant), from which sulfur is withdrawn.  The exhaust gas from the Claus catalysis plant is supplied to a desulfurizing plant.  The sulfur compounds in the exhaust gas of the desulfurizing plant axe converted to SO2 in a thermal aftertreating unit.  When the rate of the H2S-containing feed gas is below a limit, which is between 20 to 35% of the total rate of feed gas permissible for the thermal Claus process plant, then recycled exhaust gas from the desulfurizing plant (recycle gas) is admixed to the feed gas at such a rate that the rate of the mixed feed and recy-cle gases exceeds that limit.  The recycle gas is suitably heated to 200 to 400°C before it is mixed with the feed gas.

Abstract: ABSTRACT OF THE DISCLOSURE      To eliminate the need for forcibly closing the door to achieve a full closure of an automotive door, the striker which cooperates with the latch assembly of the door is not only allowed to move outwardly from its normal position but also adapted to be positively driven back to the normal position by a drive means.  When the door is to be closed for its open position, since the striker has been displaced outwardly from its normal position, latching of the latch assembly with the striker is easily achieved by hand even when the reaction force of a weather strip is substantial.  Then, the striker is positively driven inwardly to its normal position by the drive means against the reaction force of the weather strip. By appropriately controlling the drive means, very little force will be required to achieve the latching of the latch assembly with the striker and the complete closure of the door will be achieved by the drive means which may be an electric motor.
