Abstract: A method and apparatus for controlling the braking of drive wheels (W RL ) for a vehicle to brake drive wheel braking means (B RL ) in response to the occurrence of the slipping state of the drive wheels (W RL ) comprising the steps of performing a predetermined braking force (P BO ) in braking means (B RL ) in response to a manual operation before the vehicle is started, and gradually reducing the braking force of the braking means in response to the starting operation of the vehicle before the slip of the drive wheels (W RL ) is detected. Thus, this method can suppress the drive torque of drive wheels by applying a predetermined braking force to the drive wheels at the initial time of starting by means of, for example, driver's manual operation and gradually generate the drive torque after starting to start the vehicle smoothly.

Abstract: A composite structure of elastic and visco­elastic components in which dynamic loads are effective­ly damped by transmission through the viscoelastic com­ponents. The structure includes a viscoelastic layer (20), two segmented elastic layers (26, 28) having strength and stiff­ness in a desired loading direction, and two additional elastic layers (22, 24) having little strength and stiffness in the loading direction. The segmented layers (26, 28) have alter­nating segments and gaps and are disposed one on each side of the viscoelastic layer (20) in such a manner that the gaps of one segmented layer overlap the segments of the other segmented layer. Dynamic loads in the loading direction are transmitted back and forth from one seg­mented layer (26, 28) to the other, through the additional elas­tic layers (22, 24) and the viscoelastic layer (20), which thereby provides a high degree of damping. Static loads in the loading direction are transmitted through the segmented and the additional elastic layers. By appropriate selec­tion of elastic materials, the structure can be made suitable for the damping of axial or torsional loads. In the related method of manufacture, the viscoelastic and elastic materials are all cured as one structure, but without degradation of the viscoelastic layer.

Abstract: An atomic force microscope comprises a probe (21) having a sharply-pointed tip end. The probe (21) is supported on the free end portion of a cantilever (22) and is close to the surface of a specimen (20). When an interatomic force is produced, the cantilever (22) is deformed, and the probe (21) is displaced. The dis­placement of the probe (21) is detected by an optical system. A light beam emitted from a light source (87) is collimated by a lens (90), and reflected by a polar­ized beam-splitter (86), and also by a half-mirror (85). Then, the light beam passes through a quarter wavelength plate (84) and an objective lens (83), such that the light is converged on the cantilever (22). The reflected light beam from the cantilever (22) returns along the same optical path and passes through the splitter (86). The light beam is divided into two light beams at the splitter. These two light beams are reflected by respective prisms (88a, 88b) and are then incident on respective photodetectors (89a, 89b). These photodetectors (89a, 89b) detect the displacement of the probe (21).

Abstract: The invention relates to a method for the preparation of a supported procatalyst intended for the polymerization of olefins, in which particles are formed from magnesium halide and alcohol, the particles are reacted with an organo­metallic compound of any of the metals of the groups I to III, the thus obtained particulate product is activated by means of a titanium(IV) compound, and optionally a prepoly­merization is carried out for the activated particles. A problem with this kind of a method is how to form particles from magnesium dihalide and alcohol having an advantageous structure for the polymerization of ethylene and particular­ly ethylene with a narrow molecular weight distribution. The problem has in the present invention been solved by forming the particles by spray-crystallizing a mixture of magnesium dihalide and alcohol to complex particles of magnesium dihalide and alcohol and by using titanium (IV) alkoxyhalide as the titanium compound. The catalytic properties of the particles thus obtained are improved, especially after the prepolymerization carried out by means of ethylene, which leads in the polymerization to a still more active, very hydrogen and comonomer sensitive procatalyst having a better molecular weight selectivity. 
     The invention also relates to the specific use of the pro­catalyst prepared by such a method for the polymerization of alpha-olefins. By a procatalyst is meant in this context the catalyst component of the Ziegler-Natta-catalyst which is based on the transition metal and which before the poly­merization is combined with the organometallic compound of aluminium or some other metal acting as cocatalyst

Abstract: The flow of hydraulic fluid to and from an hydraulic elevator piston is controlled by a motor-actuated spool valve operated by a microprocessor. To lower the elevator, a main check valve is opened by a down piston using hydraulic fluid from the system. Pressure is equalized on both sides of the main check valve just before the latter is opened thereby allowing the use of a smaller down piston using less hydraulic fluid. This results in smoother car motion during descent of the car. The addition of a solenoid valve bleed passage to equalize pressure on both sides of the check valve also prevents rapid descent of the elevator car in the event that the spool valve were to be open at the time descent commences.

Abstract: The eddy current rail track brake has an adjustment bearing for holding the eddy current brake magnet 1 in its operative position, which bearing comprises a first adjustment part 33 on the eddy current brake magnet and a second adjustment part 34 on a non-sprung vehicle part. The first, upper adjustment part 33 is connected to the eddy current brake magnet 1 in a vertically and horizontally adjustable fashion, whilst the second lower adjustment part 34 is guided in a vertically displaceable manner on the non-sprung vehicle part 25 and can be lowered counter to the pretensioning of a pretensioned spring 30. The excitation of the eddy current brake magnet can be reduced as the travel speed decreases, in such a way that the attraction force does not exceed a specific maximum value. The pretensioning of the spring 30 is dimensioned to receive this attaction force without further compression of the spring 30. If the reduction of the excitation of the eddy current brake magnet 1 fails, the extremely high attraction force which occurs when the vehicle is travelling slowly or is stationary compresses the spring 30 and the eddy current brake magnet moves to the emergency position resting on the rail. As a result, overloading of the carrier elements of the eddy current brake magnet 1 is prevented. <IMAGE>

Abstract: A computer based combination problem processor solves constrained combination satisfaction problems for determining discrete values of respective variables in which the constraint is externally specified by a set of inequalities and equalities, and solves combination optimization problems for determining the discrete values of respective variables to minimize or maximize the value of a given objective function. The computer comprises an initial constraint violating inequality creator for creating constraint violating inequalities reciprocal to the set of inequalities; a variable value changer for changing a variable value for examination of meeting constraints; a variable selector for selecting a value of a variable whose value is unknown; a constraint violating condition creator for creating a new constraint violating condition obtained as a logical product of simplified inequalities by digitizing a variable appearing in the constraint violating conditions created from the constraint violating inequalities, when none of the values satisfy the constraints produced by the processes by the variable value changer or the variable value selector. A constraint violating condition storer stores constraint violating conditions created by the constraint violating condition creator. A variable value is changed or selected such that none of the constraint violating conditions stored in the constraint violating condition storer are satisfied. The above obtained variable value combination satisfying none of the constraint violating conditions is the solution to the constrained combination satisfaction problem or the constrained combination optimization problem.
