Abstract: ABSTRACT OF THE DISCLOSURE         A case for a disc-shaped recording medium operates together with a disc-shaped recording medium reproducing appa-ratus provided with an inserting opening through which the case is inserted, a turntable for rotating the disc-shaped recording medium, and locking mechanism and engagement releas-ing mechanism provided at the innermost part of the disc-shaped recording medium reproducing apparatus opposite to the insert-ing opening with respect to the turntable.  The case comprises a jacket having a space for accommodating the disc-shaped recording medium and an opening for allowing the disc-shaped recording medium to go in and out of the jacket, and a closing member inserted through the opening of the jacket for closing the opening of said jacket.  The closing member unitarily has a pair of engaging arms on both sides thereof which can elastically bend.  The closing member is locked by the locking mechanism upon insertion into the innermost part of the repro-ducing apparatus together with the jacket.  The engaging arms and the jacket have a slipping out preventing engaging part for preventing the closing member from slipping out the jacket in a state where the closing member is inserted into a pre-determined position within the jacket.  The engagement releas-ing mechanism has engagement releasing members which relatively make contact with and push against sloping surfaces of the engaging arms for bending the engaging arms inwards, upon inser-tion of the closing member into the innermost part of the reproducing apparatus together with the jacket.  The engaging arms and the engagement releasing members have a deviation preventing engaging part at least at a part where the engaging arms and the engagement releasing members respectively make contact, for preventing deviation within a plane perpendicular to a plane in which the closing member extends.

Abstract: Abstract of the disclosure: The 3,3'-dichloro-4,4'-diamino-biphenyl sulfate obtained in the form of a sulfuric-acid-containing solution from the "benzidine rearrangement" can be converted with good yield to a very pure dihydrochloride by heating the nearly saturated aqueous solution of the sulfate to a temperature in the range of from above 100°C to reflux temperature while adding about 50 to about 70 % of the stoichiometric amount of a chloride-ion-yielding agent, especially hydrochloric acid, subsequently cooling to a temperature in the range of from about 90 to below 100°C, adding further chloride-ion-yielding agent, and cooling to about room temperature. It is especially advantageous to add first the remaining stoichiometric amount of precipitating agent or a slight excess thereof in the temperature range of from about 90 to below 100°C, and a larger excess of up to about twice the stoichiometric amount at a later moment. The dihydrochloride obtained in a well crystallized form is advantageously washed with hydrochloric acid; filtrate and washing water can be easily worked up to hydrochloric and sulfuric acid, respectively. The product is obtained in such a pure state that it can be directly processed to dyeing agents.

Abstract: Abstract A communication link has a memory unit including a common section accessable to all ports of the link and several local sections each associated with one of the ports and accessable to its associated port, and no other port. A dual memory bus with a common bus subsystem provides access to the common mem-ory section and a local bus subsystem provides access to the local memory sec-tions.  The common and local subsystems are constructed to enable concurrent independent use.  The ports include decoding circuitry which receives signals from its associated station and in response thereto emits signals distinctively indicating the need for access to common or local memory, which emitted signals are transmitted to memory priority circuitry supplying timed signals which designate for each memory operating cycle the one of the ports which may have access to the memory.  Access is made available to the several ports in cyclic order.  The memory priority circuitry also designates for each memory cycle one of the ports for current service and responds to request signals from elements of the link indicating needs for memory access, and if the currently designated port requests memory access, the memory priority circuitry enables the currently designated port to use the common bus subsystem or the local memory bus subsystem in accordance with the signaled needs of the currently designated port, while concurrently enabling other elements of the link to use the bus subsystems not requested by the currently designated port.

The tab fastener means comprise a fastening tape and a reinforcing tape each having an adhesive surface and a non-adhesive surface, the adhesive surface of the fastening tape having one end adhered to the backsheet of one of the opposed portions of the diaper and a portion adhered to the non-adhesive surface of the reinforcing tape, and a release tape adhered to the adhesive surface of the reinforcing tape so as to permit the reinforcing tape and release tape to be separated from one another to thereby expose the adhesive surface of the reinforcing tape for adhesion to the backsheet of the other portion of the diaper.  The reinforcing tape is provided with a color which is readily discri-minable from base colors of the backsheet and the fastening tape.  Each of said fastening tape and rein-forcing tape has a free end terminating in a folded over grip tab with the grip tab of the reinforcing tape extending beyond the grip tab of the fastening tape by at least 5 mm.  The adhesive force with which the adhesive surface of the reinforcing tape adheres to the backsheet is not greater than the adhesive force with which the adhesive surface of the fastening tape adheres to the non-adhesive surface of the rein-forcing tape.
