    摘要: In a method of the modification of a fat or oil wherein a mixture (mixture A) containing a glyceride-type fat or oil to be modified (material A) and a fatty acid or a nonglyceride-type ester thereof (material B) is selectively transesterified in the presence of a catalyst having a selective transesterification activity (catalyst A); the resulting fat or oil (resultant A), fatty acid or nonglyceride-type ester thereof (resultant B) and catalyst are recovered from the reaction mixture; and then a hard butter is produced from the resultant A, the improvement comprises hydrogenating a part or all of the resultant B and reusing the hydrogenated product as a part of the mixture A.

    摘要: An electronic timepiece contains a supply voltage source which provides a supply voltage controlled in accordance with temperature, whereby power consumption is reduced by supplying the timepiece circuit with only the amplitude of supply voltage required at any particular operating temperature. Voltage control is performed in accordance with variations in propagation times of circuit elements with temperature, as determined by variations in the frequency of a ring oscillator circuit.

    摘要: To facilitate acceleration or deceleration of the stepping rate of a time-keeping counter responding to driving pulses from a frequency divider connected to a crystal-controlled oscillator, a succession of such driving pulses is taken from an OR gate with inputs receiving a basic pulse train .phi..sub..gamma. a normally present first ancillary pulse train .phi..sub..beta. spacedly interleaved with pulse train .phi..sub..gamma. and a normally absent second ancillary pulse train .phi..sub..alpha. with pulse positions offset from those of the other two pulse trains. To retard the timepiece, the pulses of train .phi..sub..beta. are blocked for a desired period; to advance it, pulses of train .phi..sub..alpha. are interpolated at a rate depending on the cadence of a series of control pulses selectively synthesized from a combination of low-frequency stage outputs of the frequency divider. Externally set selection signals are temporarily stored in a memory circuit including NOR gates with positive-feedback connections to inverting inputs thereof, the memory circuit being periodically tested by a resetting pulse recurring at a frequency lower than that of the driving pulses.
