摘要： A silicon oxide film and a BPSG film are formed on a silicon substrate to serve as insulating films, and a contact hole is selectively formed in the insulating films. An impurity diffusion layer is formed on the surface layer of the semiconductor substrate at the bottom portion of the contact hole. A second metal film serving as a metal electrode is formed to cover the BPSG film and the impurity diffusion layer, and a first metal film serving as a barrier layer is formed between the second metal film and the BPSG film and impurity diffusion layer. The first metal film prevents boron contained in the BPSG film from being diffused in the second metal film, thereby to prevent precipitation of silicon in the contact hole.

摘要： A cord-type mowing tool having a cutter body formed with at least one radially extending bore for receiving a cord serving as a grass cutting blade, and a clamping member fitted in the central bottom opening of the cutter body for forcing against the central portion of the cutter body an end portion of the cord inserted in the radially extending bore to hold the cord in place. The clamping member is threadably connected to the cutter body, so that by loosening and tightening the threadable connection it is possible to readily replace the old cord by a new cord of a predetermined length. The grass cutting tool is simple in construction, light in weight and reliable in performance.

摘要： An amplitude regulation circuit which includes a maximum detection circuit which outputs a maximum signal MAX that is distorted to some extent during and around a time when a highest-level signal switches between signals V1, V2, and V3. The amplitude regulation circuit also includes a minimum detection circuit which outputs a minimum signal MIN that is distorted to some extent during and around a time when a lowest-level signal switches between signals V1, V2, and V3. Such distortions reduce variations in amplitude detection signal AMP that represents a difference between MAX and MIN. The amplitude regulation circuit amplifies rotor position signals H1 to H3 based on amplitude detection signal AMP according to AGC, thereby maintaining amplitudes of signals V1 to V3 constant while maintaining sinusoidal waveforms.
