    摘要： A PLL comprises a current-controlled oscillator (18) for generating an output clock signal based on a current signal generated based on a phase difference between a reference clock signal and a feedback clock signal, a current source (28), and an initialization switch (26) for performing an open/close operation based on the initialization signal, the initialization switch being inserted in series to an input terminal of the current-controlled oscillator (18) and the current source (28).

    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： The present invention relates to a semiconductor device having a contact electrode structure and a method of manufacturing the same. An insulating layer is provided in a second semiconductor layer or in a junction part between the second semiconductor layer and a first semiconductor layer correspondence to a contact hole. Therefore, even if a pit generated at a junction part between the second semiconductor layer and a conductive layer in the contact hole grows, the growth of the pit is inhibited by the insulating layer, whereby leakage current caused between the first and second semiconductor layers can be reduced, a reliability of the device being thus enhanced.
