    摘要: A &Dgr;·&Sgr; type DA converter is provided with a digital circuit 21 including a PWM circuit 26 and an analog circuit 22, wherein in order to make an output of the analog circuit 22 a predetermined value, the analog circuit 22 is driven at a predetermined direct current voltage V1 (for instance, 5 V), and the digital circuit 21 is driven at a direct current voltage V2 (for instance, 3.3V) that is set lower than the direct current voltage V1. Since the digital circuit 21 and the analog circuit 22 are driven at different power supply voltages, a level shifter 23 is disposed at a boundary portion of the digital circuit 21 and the analog circuit 22, the level shifter 23 steps up a level of the PWM signal outputted from the PWM circuit 26.

    摘要: Provided is a method for making a double-walled yoke that allows an inner yoke (4) and outer yoke (3) to be integrally joined to each other both easily and securely. Such a yoke provides an adequate cross sectional area for a magnetic path of the yoke while minimizing the weight of the yoke. A tubular member (14) destined to be form the inner yoke and a cup-shaped member (13) destined to form the outer yoke are both fitted on a punch (7) and a drawing process is executed by using an appropriate drawing die (8). The outer yoke may have a small wall thickness as long as it is capable of retaining its shape during use or supporting a bearing for the motor. The inner yoke is required to be relatively small in size as long it is capable of forming a satisfactory magnetic path for the motor. A satisfactory magnetic path can be obtained if the yoke is provided with an adequate wall thickness so as to provide an adequate cross sectional area for the magnetic path.

    摘要: A semiconductor device can reduce the adverse effect of noise caused in a digital circuit, which is driven at a high drive frequency, on an analog circuit driven at a lower frequency. The semiconductor device comprises a power supply circuit provided with a voltage generation circuit, a first and second analog circuits, a digital circuit, and a level shifter. A first voltage VDD is supplied to the first analog circuit from a first terminal for driving the first analog circuit by a DC voltage. A voltage AVDD having the same potential as the first voltage VDD is supplied to the second analog circuit from a second terminal for driving the second analog circuit at a first drive frequency. A second voltage VD1 is supplied to a digital circuit from a voltage generation circuit of the power supply circuit for driving the digital circuit at a second drive frequency which is higher than the first frequency. The level shifter provided among the first and second analog circuits and the digital circuit shifts the level of signals which are input or output among the first and second analog circuits and the digital circuit.

    摘要: An electronic thermometer is provided in which the number of pulses counted in a first count and the number of pulses counted in a second count are respectively proportional to the resistance of a reference resistance and that of a thermosensing element. When the first counted value is to be adjusted so as to realize the absolute value adjustment of the thermometer, the difference between the resistance of the thermosensing element and the resistance of the reference resistor is adjusted by varying the number of counts in a counter upon whose content the timing of the second count depends. Accordingly, the absolute value precision adjustment of the electronic thermometer is realized by providing an initial logic adjustment circuit in which the number of the first clock counts is appropriately varied.
