Title: Process for preparing the piperazine salt of 2,5-dihydroxybenzenesulphonic acid monotosylate
Inventor: RIBALTA-BARO JOSEP MIQUEL
IPC: C07C303/32
Filed: 1990-08-01
Abstract: The process is characterized in that the diethyl­amine salt or the ammonium salt of 2,5-dihydroxybenzene­sulphonic acid is used as starting material, which salt is tosylated in an ammoniacal medium to lead in both cases to the production of the ammonium salt of 2,5-­dihydroxybenzenesulphonic acid monotosylate, which in its turn is converted initially to the corresponding piperazine disalt which is separated in an aqueous medium, and finally in an aqueous-alcoholic medium the piperazine salt of 2,5-dihydroxybenzenesulphonic acid monotosylate, also known as piperazine sultosylate, is obtained.

Abstract: The abutment piece (1) for laterally supporting concrete forms (12) is integrally joined to a crushable zone in the form of a compressible sleeve (2), which is adjoined by a support (8). The head (13a) of a nail (13) serving to fasten the abutment piece (1) abuts on the support. In the event of any excess energy acting on the nail (13), the sleeve (2) is compressed and damage to the abutment piece (1) is thus avoided.

Abstract: The image processing apparatus of this invention includes a novel data processing unit and memory unit. The data processing unit includes a two- to one-dimensional address coordinate value transformation unit, a two-dimensional coordinate transformation unit, an inter-pixel data calculation device and memory unit. 
     The two- to one-dimensional address coordinate value transformation unit transforms between a two-dimensional address coordinate value and a one-dimensional address coordinate value. The two-dimensional coordinate transformation unit transforms a coordinate value (x, y) on an x-y coordinate system within a predetermined area into a coordinate value (X, Y) on an X-Y coordinate system within a predetermined area. The inter-pixel data calculation unit performs a binomial operation between two pixel data. 
     The memory unit is arranged to have a variable bit length to be parallel accessible. 
     The image processing apparatus can realize good image processing without making the apparatus large in size.

Abstract: In a network, a route which can be uniquely identified is constructed by selecting an arbitrary packet-switching node and an arbitrary transmission line in an arbitrary order from the network. A route memory unit (301) stores data indicating which route is involved in which transmission line within the network. A congested state detecting unit (302) detects a congested state of a transmission line accommodated within its own node. The detected congested state is transmitted to another node by a congested state informing unit (303) as congested state information. A route identifying unit (304) receives the congested state information from the other node and retrieves a route within a corresponding transmission line from the route memory unit (301) to thereby identify the route accommodated within its node. A route control unit (305) carries out control of the congested state of the identified route on the basis of the received congested state information. As described above, since traffic passing the transmission line is classified into "route" and grouped, an object whose congestion is to be supervised is limited and each node can regulated only the traffic passing the transmission line in which the congestion occurred in units of routes.

Abstract: A mechanism (10) registers a sheet (12) of film and advances it toward an imaging station (14) where it is exposed. A registration member (20) is located along a surface of a platen (16) that receives the sheet and the member is engageable by an edge of the sheet for registering and guiding the sheet toward the station. An urging guide (26) located along another portion of the surface is skewed relative to the registration member and spaced from it so that the end portions of the guide and registration member nearest the station are spaced apart sufficiently to enable the sheet to lie flat on the surface while other portions thereof are sufficiently close together to prevent the sheet from lying flat on the surface. The guide projects above the surface and is tilted away from the registration member so that the guide imparts a component of force onto a sheet resting thereon which urges the sheet toward the registration member.

Abstract: A method and apparatus for measuring node voltage on an integrated circuit is disclosed herein. A sensing needle 10, wich is connected to supply voltage 20, is positioned directly above node 12 on integrated circuit 14. Tunneling or field emission current 30 is produced in sensing needle 10 due to the difference in potential between sensing needle 10 and node 12. Supply voltage 20 is adjusted to set current 30 to an initial value. When the voltage on node 12 changes, the current 30 will also try to change. When a change in current 30 is detected, a signal 28 is generated to adjust supply voltage 20 such that current 30 returns to its initial value. Consequently, the change in supply voltage 20 mirrors the change in voltage on node 12.

Abstract: Polycrystalline silicon interconnect elements are formed using a sandwich of a highly conductive silicide layer between two polycrystalline silicon layers. Transistors and active areas are defined using standard techniques. A layer of refractory metal is deposited over the integrated circuit device, and heated to form a silicide with exposed monocrystalline and polycrystalline silicon areas. The depth of the silicon formed is not very large, and is consistent with protecting shallow junctions in the active areas of the device. Sheet resistance of the polycrystalline silicon conductive elements is maintained at low levels by the additional silicide layer within the sandwich.
