Patent JP-S629877-B2 (JP)
IPC: H02P8/02
Filed: 1977-04-23
Abstract: An analog electronic timepiece has a stepping motor for rotationally driving the timepiece hands. The motor is driven by normal driving pulses during normal load conditions and in the event the normal driving pulses are unable to effect rotation of the motor, correction driving pulses of longer pulse width than the normal driving pulses are used. A detection circuit detects whether or not the motor has rotated by switching a resistance element in series with the motor drive coil after the application of each normal driving pulse. Rotation and non-rotation of the motor is determined by measuring the voltage across the resistance element and comparing the measured voltage with a reference voltage.

Filed: 1986-04-12
Abstract: L-(d)-lactic acid, the dextrorotatory isomer of lactic acid, is an effective plant growth regulant which exhibits classical growth regulant activity at very low concentrations and dosage rates. It can be employed to beneficially stimulate the growth of all plant varieties and is particularly useful for stimulating the growth of commercial crops. As is the case with other growth regulants, L-lactic acid can also be employed to inhibit the growth of plants when applied at sufficiently high concentrations. Thus, L-lactic acid can be employed to stimulate the growth of desired plants, to stimulate the fruit production of fruit-bearing plants, and to inhibit the growth of undesired vegetation. Novel compositions which comprise mixtures L-(d)-lactic acid and one or more preservatives which are sufficient to prevent the hydrolytic and/or bacterial decomposition of the active isomer are also disclosed.
