    • In a method of making a semiconductor device, an active layer and a heavily doped cap layer are formed in turn on a semiconductor substrate, a first electrode is formed on the cap layer, a mask of a two-layer structure is formed on the cap layer, with the mask having an insulating film pattern having a non-inverted tapered opening, and a resist pattern having an inverted tapered opening and continuous with the non-inverted tapered opening, these openings being separated by a predetermined distance from the first electrode, and then a recess is formed, by performing an isotropic etching of the heavily doped layer exposed in the openings, with the recess having a bottom surface and a side wall surface rising from an edge of the bottom surface toward the upper edge with a constant radium off curvature. An oblique vapor deposition is then performed to form a second electrode to cover the bottom surface and the part of the side wall surface.

    • A speech synthesizer is disclosed with the capability of stretching and compressing the speech time base without changing the pitch of the synthesized speech. One frame of speech is represented during a given time base by LPC parameters which are sampled a constant number of times per frame and stored in memory. Speech is synthesized by fetching each of the stored LPC parameters for each frame and subjecting the parameters to interpolation, synthesizing the interpolated parameters and converting the synthesized parameters to analog format. A decrease in the speed of the reproduced speech is produced by lengthening the time interval of interpolation between the fetching of each of the stored LPC parameters which have been previously stored for each frame. An increase in the speed of the reproduced speech is produced by decreasing the time interval of interpolation between the fetching of each of the stored LPC parameters which have been previously stored in each frame.
    • 公开了具有在不改变合成语音的音调的情况下拉伸和压缩语音时基的能力的语音合成器。 在给定的时基中通过LPC参数表示一帧语音,每个帧对每帧进行常数次的采样并存储在存储器中。 通过取出每帧存储的LPC参数并对参数进行插值,合成内插参数并将合成参数转换为模拟格式来合成语音。 再现语音的速度降低是通过延长先前为每个帧存储的每个存储的LPC参数的取样之间的内插时间间隔而产生的。 通过减少在先前存储在每个帧中的每个存储的LPC参数的取样之间的插值的时间间隔来产生再现语音的速度的增加。

    • A tennis racket includes a frame that includes a shaft and a looped frame portion, the shaft having a grip formed on one end side thereof, the frame portion being joined to the other end side of the shaft and forming a hitting face with a string being strung across and a plurality of insertion holes that provide communication between an inner peripheral side surface and an outer peripheral side surface of the frame portion and through which the string is inserted. Shock absorbing portions and hard portions are provided in an alternating fashion on at least a part of the outer peripheral side surface of the frame portion. Each shock absorbing portion is formed between insertion holes that are adjacent to each other. Each hard portion is formed between insertion holes that are adjacent to each other and is less elastically deformable than the shock absorbing portion.
