Disclosed is a calcium channel antagonist effective as a single substance for attaining dual purposes of inhibiting secretion of parathyroid hormones and of promoting absorption and utilization of calcium in human body as well as a process for preparing the calcium channel antagonist. According to the present invention the calcium channel antagonist is prepared by baking a calciferous material of plant origin at a temperature of 500-1000° C. under reduce pressure or vacuum and extracting the baked material with and acidic substance. The calcium channel antagonist may be incorporated with a conventional calcium preparations to enhance bioavailability of calcium. Further, the calcium channel antagonist of the present invention may be processed to calcium preparations in the form of porous granules.

A method of continuously casting molten metal has the step of feeding molten metal into a mold to produce a casting continuously while generating an electromagnetic field in the mold by applying a high frequency to the mold. The application of the high frequency is controlled in such a manner that a magnitude of an electromagnetic field which is applied to a solidification shell forming start location of the mold becomes equal to or greater than a minimum required flux density to be applied to the mold. The minimum required flux density is determined according to the following equation: B min = 1130 × t n - 5 f × ( t n - 0.05 ) where t n = cos - 1 ( v / 2 π × f m × a ) / ( π × f m ) Bmin: minimum required flux density (gauss) tn: negative time strip (second) f: frequency in electromagnetic field (kHz) v: casting velocity (m/sec) fm: number of oscillation or frequency of mold (Hz) a: one-way stroke of mold (m).

The preparations are preferably in the form of liquids, granules, tablets and capsules.
摘要:
One driver having external electrodes arranged over both surfaces of a piezoelectric ceramic plate polarized in the direction of its thickness, and one generator having two mutually opposed interdigital electrodes on one or both surfaces of a piezoelectric ceramic plate and alternately polarized in the direction of its length between the electrode fingers of the interdigital electrodes are formed combined in alignment in the direction of the length of the piezoelectric ceramic plate. Alternatively, the driver and generator may be formed in alignment in the direction of the width of piezoelectric ceramic plate. By applying a low voltage to this piezoelectric ceramic transformer from the driver at a resonance frequency of a longitudinal vibration of second order mode of the piezoelectric ceramic plate, a high voltage can be picked up from the generator. Here, through connection of the input terminals and output terminals at the nodes of vibration, failure due to vibration of lead wires can be prevented, thereby obtaining a compact and slim transformer element that provides high reliability. A plurality of drivers and generators may also be employed, and in addition, an interdigital electrode may be used in the driver as well as in the generator.

A network control system for controlling a plurality of nodes respectively corresponding to, and provided in, a plurality of radio zones. Each node has a corresponding base station. A mobil station travels among the plurality of radio zones and communicates with the base station of a respective node when travelling in a radio zone corresponding to the respective node.

A data processing apparatus has a card inserting unit provided with a card inserting port for a contact type card which is disposed inside of a loop-shaped antenna through which data is transmitted to and received from a non-contact type card. Even if various kinds of cards are accessed, the sequence of accessed cards cannot be different from the sequence of cards being processed. With this arrangement, in a data processing apparatus capable of commonly using two or more kinds of cards including the contact type card and non-contact type card, the sequence of users utilizing the apparatus cannot be different from the sequence of data being processed.
摘要:
A pair of magnetic recording parts are axially spaced on a rotating shaft and a pair of magnetic heads for recording and reproducing a location signal are respectively opposed to the respective magnetic recording parts. Torque of the rotating shaft is calculated based on a quantity of a phase shift of the location signals reproduced by the respective magnetic heads and rotating speed of the rotating shaft is calculated based on a reproducing frequency of the location signal reproduced by one of the magnetic heads so that the magnetic recording parts and the magnetic heads serves as a sensor for detecting both torque and rotating speed. Thus, a number of parts of the sensor is lessened, being compacted with low cost.
