摘要： By reducing the number of seek operations in an operation to play back a signal from a recording medium, the amount of data temporarily stored in a read buffer memory employed in a signal recording/playback apparatus is large enough to be output as a playback signal during a seek operation, allowing a continuous playback operation to be carried out. In order to reduce the number of seek operations, a signal is always recorded onto the recording medium in continuous free areas each having a size equal to or larger than a predetermined recording/playback time length which is typically set at 1 minute. If it is necessary to insert an additional signal having a length smaller than the predetermined recording/playback time length into a point of insertion in an area already occupied by an existing signal, a continuous free area with a size equal to or larger than the predetermined recording/playback time length is newly allocated to the additional signal. The additional signal is then recorded in the free area instead of being inserted into the point of insertion. Since the free area is larger in size than the length of the additional signal, the rest of the free area is filled up with a portion of the existing signal adjacent to the point of insertion.
摘要翻译：通过减少用于从记录介质播放信号的操作中的寻道操作次数，临时存储在信号记录/重放装置中使用的读缓冲存储器中的数据量足够大以作为重放信号被输出搜索操作，允许执行连续播放操作。为了减少搜索操作的数量，信号总是被记录在连续空闲区域中的记录介质上，每个区域的大小等于或大于通常设置为1分钟的预定记录/重放时间长度。如果需要将具有小于预定记录/重放时间长度的长度的附加信号插入到已经被现有信号占据的区域中的插入点中，则具有等于或大于预定记录/重放时间长度的尺寸的连续空闲区域记录/播放时间长度被新分配给附加信号。然后将附加信号记录在空闲区域中，而不是插入插入点。由于空闲区域的尺寸大于附加信号的长度，所以剩余的空闲区域被填充有与插入点相邻的现有信号的一部分。

摘要： To determine leadframe tip positions, a circular arc portion where leadframe tips are to be arranged is determined so as to be opposed to each of the four corners of a die pad by performing a search. Then, straight line portions are set so as to extend from the circular arc portion and to be opposed to the die pad sidelines. The shape of each leadframe tip on the circular arc portion is defined as a region that is sectioned by two concentric circles and two radial rays extending from the center of the concentric circles. The division between the circular arc portion and straight line portions and the setting of the center of the circular arc portion are performed automatically. The leadframe tip width and interval are determined independently of each other.

摘要： A self-clinching nut fastener, which may be used as a pierce nut, having a central cylindrical pilot portion, an annular flange portion surrounding the pilot portion, having a generally flat annular panel-supporting end face and an annular groove defined in the flange end face surrounding the pilot. The bottom wall of the groove includes a projecting convex annular protuberance which extends circumferentially around the pilot and radially from the pilot to a midportion of the groove bottom wall spaced from the groove outer wall and the groove outer wall is inclined inwardly toward the pilot to define a restricted opening to the annular groove. The installation apparatus includes a die button having a projecting annular clinching lip configured to be received within the nut groove. The method of installation includes locating a panel on the die button lip with the die button lip coaxially aligned with the nut groove, then driving the nut against the panel to deform an annular portion of the panel into the nut groove and against the annular protuberance to deform the panel portion beneath the inclined outer groove wall and preferably radially inwardly against the pilot portion. In the most preferred embodiment, the protuberance comprises a plurality of semi-circular protuberances which are integral with the pilot portion and extend radially to beyond the radial center of the grooved bottom wall and the panel is deformed against the groove bottom wall into radial channels between the spaced protuberances preventing relative rotation of the nut on the panel.

摘要： A pierce nut having a central pilot, a cylindrical flange portion surrounding the pilot and a groove in the flange portion having at least one inclined side wall and a bottom wall having a convex annular protuberance preferably comprising spaced arcuate protuberances extending around the pilot which deforms panel metal beneath the inclined side wall and providing anti-rotation means when the nut is attached to a metal panel. The outer groove side wall includes radial notches or grooves which receive panel metal to provide anti-torque means. The improved die button includes an annular lip having an inside piercing edge spaced from the end to pierce a smaller slug and an annular convex fillet which deforms more panel metal into the nut groove to form a secure mechanical interlock between the nut and panel.

摘要： Image signal recording apparatus and methods are provided for recording first and second image data on a record medium wherein the first image data are obtained through sampling of image signals at a first data rate and the second image data have a second data rate lower than the first data rate such that the second image data may be reproduced by apparatus operating at the second data rate. The second image data are formed from the first image data and recorded together with at least a portion of the first image data in predetermined areas of the recording medium. The portion of the first image data recorded on the recording medium is selected such that the first image data may be derived by reproducing apparatus operating at the first data rate from the second image data and the portion of the first image data. Area discriminating codes are recorded on the recording medium for identifying the predetermined areas in which the second image data and the portion of the first image data are recorded.

摘要： A video signal processing apparatus for performing editing of video signals includes a memory into which one field or one frame of a moving picture video signal from a video camera is written and a crossfading circuit, wherein a still picture of the video signal is written in the memory at a selected time or at a time the video camera stops operation. Thereafter, when the video camera resumes operation, the contents of the memory are read out, so that the real moving picture video signal being currently provided by the video camera and the previous still picture video signal read out from the memory are crossfaded. The video signal processing apparatus can also cooperate with a video tape recorder for storing in the memory a still picture derived from the video tape recorder, so that when the video camera starts its operation, the real moving picture video signal produced by the video camera and a still picture video signal from the memory are crossfaded.
