Abstract: A method for producing a metal sheet with raised lines uses a rolling mill including roll stands. In a preparing step, a grooved roll is prepared, the grooved roll including grooves. In a choosing step, a stand at least one stage before the last stand is chosen. In an incorporating step, the grooved roll is incorporated in as an upper roll of the chosen, specified stand. In a forming step, a workpiece is formed into a metal sheet with raised lines formed corresponding to the respective grooves. In the forming step, a maximum rolling reduction achieved by rolls of the specified stand is set to a provisional value that is lower than a required value. After the leading edge of the workpiece reaches the stand next to the specified stand, the maximum rolling reduction of the specified stand is changed to the required value.

Abstract: A stable pharmaceutical preparation containing a human growth hormone having a molecular weight of about 20,000, or a derivative thereof, can be formulated by adding a water soluble heterocyclic compound, such as creatinine, a salt of acetyltryptophane and nicotinamide, to prevent the insolubilization of the human growth hormone or the derivative thereof in an aqueous solution.

Abstract: In an analogue electronic timepiece the hands are moved by a stepping motor driven by a time standard signal supplied from a generating circuit comprising a quartz oscillator. In order to amend the time in a reverse direction, for example to correct for a different time zone, means is provided for detecting the angular position of the rotor of the motor and for supplying current in the reverse direction to the coil of the motor when the rotor reaches a predetermined angular position so as to cause the motor to rotate in a reverse direction.

Abstract: A miniature reversible motor comprising a rotor having a plurality of magnetic pole pairs, and a stator having a pole face opposite the periphery of the rotor. A magnetic member of high permeability magnetic material is positioned proximate the periphery of the rotor and magnetically couples with the magnetic poles of the rotor for determining a direction of rotation of the rotor. A positioning mechanism is operable for changing the position of the magnetic member relative to the periphery of the rotor to change the direction of rotation of the rotor determined by the relative position of the magnetic member and the periphery of the rotor.
