A vehicular slide door apparatus includes a slide door that is movable along a lengthwise direction of the vehicle body for opening and closing an opening area formed in the lateral side of the vehicle body, a rail secured to the lateral side of the vehicle body to extend in the lengthwise direction of the vehicle body, and a driving device for moving the slide door. The rail possesses first and second side walls and a roller operatively connected to the slide door is slidably fitted in the rail. A guide pipe extends along the rail and is secured to a surface of one of the side walls of the rail to strengthen the rail. A cable passes through the guide pipe in a movable manner and includes one end connected to the driving device and an opposite end connected to the slide door.

A filter apparatus has a current-detecting coil. The coil detects a high-frequency leak current flowing from the phase-windings of a motor to the earth terminal through the closed case of a compressor. A current-canceling circuit generates a current similar in waveform to the high-frequency leak current detected by the coil. The current thus generated cancels out the high-frequency leak current.

An object of the present invention is to provide a low cost, high performance, thin structure rotary motor for driving medium used in magnetic disk drive unit, optical disk drive unit or the like, in order to improve the productivity of terminating processing and the reliability of the coils. Magnetic materials which are divided to a plurality of blocks or divided corresponding to respective magnetic pole teeth are connected by means of thin portions. The respective magnetic pole teeth are wound continuously with wire without cutting the wire at the positions in which the thin portions are connected. When a stator is assembled, a plurality of blocks or magnetic pole teeth are disposed on a substrate by separating or bending the thin portions.

A humidity sensor and a method for producing the same, in which an insulating film is first formed on a substrate. A first sensing film is formed on a first electrode to be separated by a space from the insulating film. A second sensing film of the same material as the first sensing film is again formed on the first sensing film and the insulating film, the space therebetween being filled with the second sensing film. Thus a uniform surface etching of the second sensing film is effected, to obtain a continuous flat film layer composed of the sensing film and the insulating film with a continuous flat surface, and in which a second electrode is formed on at least the sensing film.

A synthetic mordenite molded body is prepared by a process wherein a starting mixture comprising, as the main components, a silica source, an alumina source, an alkali source and water is molded into a starting molded body, the molded body is calcined and the calcined molded body is heated in an aqueous solution of sodium silicate. The starting mixture has incorporated therein a mordenite seed crystal powder. When the molded body is calcined, the temperature is elevated by heating to a calcination temperature not lower than 400.degree. C. at an average rate of at least 10.degree. C./min and calcination is conducted at the calcination temperature within a time period of 2 hours. When the calcined molded body is crystallized, an aqueous solution of sodium silicate having an SiO.sub.2 concentration of 7 to 25% by weight, an Na.sub.2 O concentration of 2 to 8% by weight and an SiO.sub.2 /Na.sub.2 O molar ratio of from 0.9 to 4.0 is used as the aqueous solution of sodium silicate.

A copper film is formed by bringing the vapor of an inorganic compound of copper, such as cuprous nitrate that vaporizes upon heating, into contact with a reducing gas in the reaction chamber, so that copper ions are reduced into metal copper that is to be deposited on a substrate. The obtained copper film exhibits very good step coverage and contains very little impurities, lending itself well for forming interconnections of a semiconductor device that has a high degree of integration.

An output circuit includes a first transistor coupled to an external terminal and having a gate terminal that receives a first drive signal. The first transistor pulls down a potential at the external terminal when activated in accordance with the first drive signal. The output circuit also includes a capacitor. The capacitor includes a first end coupled to the gate terminal of the first transistor. A clamp circuit, coupled to a second end of the capacitor, clamps the second end of the capacitor to a potential corresponding to the operation of the first transistor. The first transistor includes a drain terminal that is not coupled to the capacitor but is coupled to the external terminal.
