Inventor: JOERG KLAUS
IPC: G03F7/32
Filed: 1990-11-14
Abstract: Abstract of the Disclosure A developer concentrate is described which is used by diluting with tap water to give a ready-to-use   developer   for   negative-working   exposed reproduction  layers  on  a  base.    The  developer concentrate is a mixture which includes water, an organic  solvent, an  alkali  agent,  an  anionic surfactant, an n-alkanoic acid and/or its salts, an emulsifier,  a  buffering  substance  and,  as  a complexing  agent,  an  alkali-metal  salt  of  an oligomeric    phosphate    and/or    of    N-(2-hydroxyethyl)ethylenediamino-triacetic acid.   The developer  concentrate  according to  the  present invention exhibits,  in particular,  the advantage that it is stable as a concentrate, i.e., exhibits no phase separations, precipitates or turbidities, etc.,  and can be diluted without difficulties to produce the ready-to-use developer.  The latter is also   stable   and   exhibits   optimum  developer properties.

Title: Composition for coating concrete
Inventor: LAVY AVRAHAM
IPC: E01C7/30
Filed: 1990-12-21
Abstract: A B S T R A C T:            A composition for application to concrete asphalt surface, such as highways, airfield landing strips and the like. The composition penetrates to a certain depth into the surface and results in an improved resistance to mechanical stresses and abrasion as well as against deterioration due to solar radiation.  The impregnation with the novel composition also prevents to a large extent water penetration.          The main ingredients of the compositions are bitumen or an equivalent, a polymerizable monomer or monomer mixture, an inert mineral filler, water and a curing agent for the monomer.  It is advantageous to add a U.V. protective agent to enhance resistance to deterioration due to solar radiation.

Inventor: INAJI TOSHIO
IPC: H02P6/18
Filed: 1991-06-19
Abstract: Disclosed is a brushless DC motor which does not have a position sensor for detecting a rotational position of the rotor, in which conducting phases of the stator windings to be detected are subsequently selected by multi-phase selection signals in response to a conducting state of the stator windings, then a pulse signal train is generated by detecting the counter electro-motive forces induced in the conducting phases subsequently selected and a trapezoidal waveform signal is formed by a slant waveform signal generated in response to the pulse signal train thus obtained.   Furthermore,  with the trapezoidal waveforms signal thus formed as position signal of the rotor, an electric current signal having a trapezoidal waveform is supplied to the stator windings, resulting in smooth commutation of the con-ducting phase of the stator windings.  When to be started, phase commutation of the stator windings is carried out forcibly by means of a pseudo output pulse, thus being capable of providing a starting characteristic compatible with that obtained in con-ventional motors having a rotor position sensor.

Title: Unified distributed simulation process
Inventor: MCAFFER JEFF
IPC: G06F7/00
Filed: 1991-07-30
Abstract: Abstract A computer simulation system and method for creating complex simulations for a large number of objects.  Each object in the simulation is assigned a local virtual time (LVT) and a global virtual time (GVT) as well as being assigned a variable aggressiveness Ai, where 0  ? Ai? ?, and a variabls risk Ri where 0 ? Ri? ? , Ai is the number of time units an object is capable of looking ahead to define a receive window within which an object is capable of receiving and processing messages.  Ri is the number of time units into the global future that an object is capable of sending messages to define a send window for each of the objects.          This provides a unified distribution simulation system that allows variable asynchronous message passing with the synchrony between objects being varied by adaptable aggressiveness Ai and risk Bi parameters for each object in the simulation with each parameter being adjusted depending on circumstances in the simulation.  This results in a system which is more flexible and one that is able to take better advantage of available computing resources than those presently available.
