A resistance element having a reduced occupied area and a high resistance which may be employed as a load resistor used in, for example, a static memory device. A high-resistance area is formed using a relatively thin film, while an interconnection area is formed using a relatively thick film, and these films are provided in such a manner that the thin film is in contact with the upper side of the thick film (the relatively thick film is a first-level film, and the relatively thin film is a second-level film).

An elevator control apparatus comprises an inverter device for supplying an induction motor for driving an elevator cage with AC electric power of variable voltage and frequencies and control equipment for controlling the output voltage and frequencies of the inverter device in response to signals produced in floors served by the elevator and in an elevator cage. The inverter device is constructed by a converter unit for converting AC electric power to DC electric power, at the input end of which a capacitor is connected in parallel with an AC electric source, an inverter unit for inverting the DC electric power converted in the converter unit into AC electric power, at the output end of which a capacitor is connected in parallel with an induction motor for driving the elevator cage and a DC reactor connected between the converter unit and the inverter unit.The thus constructed elevator control apparatus does not cause interference in electric appliances such as audio equipment, computer etc. existing within a building in which the elevator is installed.

A CMOS IC is formed on a semiconductor crystalline surface having a plane azimuth (110) or (023), or of a plane azimuth close thereto (plane azimuth substantially in parallel with the above-mentioned planes), in order to increase the speed of operation.At low temperatures, dependency of the carrier mobility upon the plane azimuth becomes more conspicuous as shown in FIG. 1, and the difference of mobility is amplified depending upon the planes. Therefore, employment of the above-mentioned crystalline planes helps produce a great effect when the CMOS device is to be operated at low temperature (e.g., 100.degree. K. or lower), and helps operate the device at high speeds.

In a cage position detector for a hydraulic elevator, there is provided a detector for measuring the time duration of the power failure, when the power fails. An amount of sinkage of a cage during the power failure is obtained by the time duration of the power failure and an average sinkage amount per unit time provide in advance. A cage position, which has been detected just before the power failure, is corrected by the above obtained amount of sinkage of the cage. A cage position, from which the elevator is to reopen a normal operation for service after the recovery of power, is specified by the corrected cage position.According to the present invention, even though the cage sinks during the long power failure, it is prevented to lose the true present position of the cage, from which the elevator is to reopen the normal operation after the recovery of power.

A semiconductor device including at least a resistance element formed of polycrystalline silicon having a high resistivity. An electrode is provided on the high resistance polycrystalline silicon region with a silicon dioxide film and a silicon nitride film being interposed therebetween. The electrode is coupled to the ground potential. In this manner, high stability is obtained in the behavior of the resistance element inasmuch as the formation of a parasitic MOS device under said high resistance region is suppressed, and the threshold voltage of any such MOS device is made raised.
