Abstract: Vitamin D₂ analogs in which a cyclopentane ring is introduced onto the 25-carbon of the side chain of 1α,25-dihydroxyvitamin D₂ and its 24-epimer are described. The compounds are characterized by a marked intestinal calcium transport activity while exhibiting much lower activity than 1α,25-dihydroxyvitamin D₃ in their ability to mobilize calcium from bone. Because of their preferential calcemic activity, these compounds find utility in the treatment of diseases where bone formation is desired, such as osteoporosis.

Abstract: A protection mechanism includes means for taking an input binary value and generating a unique key value as well as performing the reverse operation of taking a key value and generating an input binary value. The mechanism includes a scrambler which includes an array having a number of multibit container locations for storing a unique sequence of random numbers. The scrambler forms another binary value by rearranging the bits of the input binary value as a function of the random number values in addition to altering the states of such bits as a function of the random number values and the numeric bit position values of sources of the input binary bits. The resulting binary value is applied to an alphanumeric encoder which converts the binary value into a series of alphanumeric characters containing a valid key value.

Abstract: When a video signal is recorded on a magnetic tape (14), a high frequency signal component of data converted by a DCT (discrete cosine transform) converter 3 in a DCT fashion or an outer code is recorded on a recording track at its beginning portion in which a waveform of a reproduced output is considerably deteriorated in amplitude when a reproducing head (15) starts to reproduce the recording track. Also, a low frequency signal component of data converted by the DCT converter (3) in a DCT fashion is recorded on the recording track at its succeeding portion in which the reproducing head (15) can stably reproduce the recording track by a recording head (13). The high frequency signal component or outer code is recorded on the area corresponding to the track at its beginning portion in which a waveform of a reproduced output is considerably deteriorated in amplitude when the reproducing head starts to reproduce the same upon playback and the low frequency signal component of data is recorded on the track at its succeeding portion in which the tracing of the reproducing head is stabilized relatively so that, even if a reproducing error occurs and increases because a waveform of a reproduced output is deteriorated in amplitude when the reproducing head starts to trace the recording track, then an amount that a picture quality of a reproduced signal is deteriorated by such error can be reduced considerably.

Abstract: A magnetic bearing is provided with a simulating circuit (10) for estimating a displacement of a rotor (1) on the basis of a force which is exerted on the rotor (1). An output of the simulating circuit (10) is compared with an actual displacement signal. A delay circuit (13) and a subtracter (21) are provided to subtract a run-out which was estimated one period before the rotation of the rotor from the displacement signal. A displacement signal from which the run-out component was eliminated is set to a new displacement signal. A signal which is obtained by adding an estimation run-out of one period before, namely, an output of the delay circuit to the run-out which was estimated by comparing the output of the simulating circuit (10) with the new displacement signal is newly inputted to the delay circuit (13). Due to this, the run-out component is eliminated from the displacement signal of the magnetic bearing, a load of power amplifiers (7a, 7b) for driving electromagnets (3a, 3b) is reduced, there is a surplus for a saturation which is caused in a high frequency band, the reliability of a control system is improved, and a deterioration of a positional accuracy which is caused by the run-out is prevented.
