Abstract: 1.1. The invention concerns a forming fabric for the wet end of a paper machine, consisting of at least two complete woven fabrics of any desired type of weave which are held together by longitudinally and/or transversely orientated binding threads, the longitudinal threads of the fabrics forming longitudinally orientated fibre support points and the transverse threads forming transversely orientated fibre support points. 
<??>1.2. To adapt the surface structure of the paper to the particular intended use with the aid of fabric construction means without altering the character of the basic fabric construction, it is proposed that at least some of the longitudinal threads and/or transverse threads of the forming fabric be partnered by threads which in at least one repeat are parallel to and hence follow the same method of interlacing as the particular longitudinal and/or transverse threads and to alter the numerical ratio of the longitudinally orientated fibre support points to the transversely orientated fibre support points of the forming fabric.

Abstract: A controlling apparatus comprises a portion (11) for calculating a deviation between a process variable from a controlled system and a target value, a first portion (10) for receiving the deviation and executing a velocity-type I controlling calculation to obtain a first calculation output, a second portion (14, 32) for receiving the deviation and executing a velocity-type P or PD controlling calculation to obtain a second calculation output, a summing portion (15) for summing the first and second calculation outputs to obtain a velocity-type manipulative variable, a conversion portion (16) for converting the velocity-type manipulative variable into a positional manipulative variable, a portion (17, 19) for limiting a magnitude of the positional manipulative variable between upper and lower limits, and limiting a change rate of the positional manipulative variable within a predetermined change rate, and a judgment portion (20) for judging whether or not the positional manipulative variable is deviated from at least one of upper and lower limits and the change rate. The first portion includes an output unit (13) for the first calculation output, and a stopping unit (23) for selectively stopping the output of the first calculation output. When the judgment portion (20) determines that the manipulative variable is deviated, it supplies a signal to the stopping unit (23), and stops the summing operation by the summing portion.

Abstract: To output desired high purity signals, a frequency synthesizer was made to synthesize reference signals from a first and second signal generators (11, 12) in the same frequency band as a desired frequency band. Thereby, the resolution of the frequency synthesizer becomes twice the step ΔF. Also, the frequency synthe­sizer can interpolate the step size of the first signal generator with half the number of steps. While, heretofore, the 100-MHz step size was interpolated with Fq = 0, 10, 20, 30, 40 and 50 MHz, Fq = 0, 20, 40 MHz interpolation is made possible. This permits the syn­thesis of 580 MHz to 1280 MHz. In this case, however, the minimum difference between the sum and difference frequencies from the first and second signal generators (11, 12) is 40 MHz and the lowest frequency is 20 MHz. Thus, depending on mixer isolation, the spurious meas­ures become difficult. The frequency synthesizer of the present invention pays attention to the fact that 20 MHz step signals can be synthesized at frequencies which are integral multiples of Fq (multiples of 0 and 5 are excluded). When two-fold Fq is used, the minimum dif­ference between the sum and difference frequencies out­put from a mixer (13) is 80 MHz and the lowest used frequency is 40 MHz. The spurious measures by a PLL circuit (14) becomes easy. A frequency detector (18) forces the free-running frequency of a VCO included the PLL circuit. Control Data P and Q to the first and sec­ond signal generators are supplied from a control sec­tion (27) based on data Fi set by as frequency setting section (28).

Abstract: Spherical cement particles are produced by (a) grinding cement clinker particles by a high speed impact treatment in apparatus of Fig. 1 wherein the particles are rotated and scattered by blades on a rotating plate and multiply impacted until (Fig. 6) the particles are spherical, or (b) by mechanochemical surface fusion. 
     The sphered cement may be encapsulated (Fig. 3) by attaching fine cement powder, silica-fume or other powder to its surface. 
     These sphered particles preferably have at least 60 wt% thereof of diameter 3.9 to 30 µm. 
     Before the particles have been completely sphered, the powder formed therefrom can be attached (Fig. 5) to fill the recesses in the particles, thus rounding them. 
     Alternatively (Fig. 4), silica fume particles are coated with ultrafine particles of cement clinker. 
     Cement mortar is made from the cements, or low-hydration concrete using the sphered cement, aggregate and water in a proportion of 1:2.5 to 8.0:0.17 to 0.75. The resultant cured concrete is of high strength.

Abstract: A magnetic disk drive includes a resilient load pin (11, 12) engageable with a flexure (4, 5) to urge the same until a floating magnetic head (6, 7) having a negative pressure slider (6a, 7a) is displaced toward a magnetic head (1, 2) beyond a floating position. This ensure that the magnetic head (6, 7) is placed into the floating position even when it is slightly displaced from an accurate assembling position due to an assembling error. Since the resilient load pin (11, 12) is resiliently bendable when it urges the flexure (4, 5) to move the magnetic head (6, 7) toward the magnetic disk (1, 2) beyond the floating position, a frictional engagement between the magnetic head (6, 7) and the magnetic disk (1, 2) does not take place.

Abstract: An error detecting and recovery subsystem which can be easily modified for use with any data processing system which is being monitored is disclosed. The subsystem employs a user editable file including the rules for defining the system state, the error states, and the sequences of recovery actions to be taken depending upon the comparison between the system state and the error states. The rules for defining the system state, include means for determining selected system variables, and the sequences of recovery actions are specified using an index into a set of elemental recovery actions. Because the system state, error state, and sequence of recovery actions are defined in a user editable file, modifications to the error detection and recovery scheme can be made without recompiling the recovery subsystem program code. Such modifications to the subsystem may therefore be made on a real time basis.
