摘要： A dissimilar material joint is formed by arranging a plurality of joint segments consecutively in a longitudinal direction. Each joint segment is formed by joining and integrating together a first member, an intermediate member, and a second member by explosive welding. A groove is formed in a joint end face of each joint segment, the joint end face being joined to another one of the segments, the groove spacing apart an end face of the first member and an end face of the second member from each other in a stacking direction. In the dissimilar material joint, the end faces of the respective first members of the joint segments that are adjacent to each other are joined together by welding, and the end faces of the respective second members of the joint segments that are adjacent to each other are joined together by welding.

摘要： A welding tool is inserted into an object in a rotation-stopped state, and the welding tool is rotated after insertion, thereby the object is stirred by frictional heat. The welding tool is inserted into the object free of whirling. The welding tool can be prevented from inserting in a position shifted from the target welding position. Namely, the welding tool is precisely inserted in the target welding position and members of the object can be welded in the target welding position free of shifting.

摘要： A speech coder using a pitch synchronous innovation code excited linear prediction (PSI-CELP) speech coding system. The speech coder is capable of representing a portion which is not sufficiently represented by an adaptive codebook in a periodic portion of input speech and capable of improving the quality of reproduced speech. The periodicity corresponds to the pitch cycle of input speech by preliminarily reproducing speech from simple impulse trains. The speech coder depending on the particular embodiment includes an adaptive code book, a fixed code book, a noise code book, and a pulse codebook. A pulse code book stores a plurality of types of codevectors corresponding to pitch waveforms of voiced sounds. At the time of coding input speech, the pulse code book is searched.

摘要： A speech synthesizing apparatus includes an interpolation pitch calculation circuit wherein an interpolation pitch is calculated at every frame periods based upon a speech parameter. Specifically, a difference between a target value and a present value is stored in a shift register of 16 bits, and then, in order to omit the figures below the first place of decimals and to divide the difference by the number of subframes, the shift register is shifted rightward by 7 bits. If a numeral value of the shift register is negative, "1" is added to the number of units of the numeral value in an adding circuit such that an absolute value of the numeral value becomes smaller. When the numeral value of the shift register is positive, the numeral value outputted from the shift register is set in an interpolation pitch register as it is and, when negative, an output of the adding circuit is set in the interpolation pitch register.
