    • The object of the present invention is to eliminate a double image of a display apparatus for automobiles in which an image of displayer is reflected by a transparent reflection plate toward a driver's seat so that the display image for displaying information on the condition of the vehicle such as vehicle speed can be seen as a virtual image. A display apparatus for automobiles according to the present invention comprising: a displayer for emitting display light; a reflection plate having a first surface on a driver's seat side and a second surface on a side opposite to the driver's seat, the display light diagonally falling on the first surface and being reflected on the first surface to be directed to an eye range, a display image of the displayer being recognized from the driver's seat side within a display range on the first surface, at least a portion of the second surface corresponding to the display range of the first surface being diagonally disposed in relation to the first surface.
    • 本发明的目的是消除用于汽车的显示装置的双重图像,其中显示器的图像被透明反射板反射到驾驶员座位,使得用于显示关于车辆状况的信息的显示图像 因为车速可以看作是一个虚像。 根据本发明的用于汽车的显示装置,包括:用于发射显示灯的显示器; 反射板,其具有在驾驶员座侧的第一表面和与驾驶员座椅相对的一侧上的第二表面,所述显示灯对角地落在所述第一表面上并被反射到所述第一表面以被引导到眼睛范围, 在第一表面的显示范围内从驾驶员座侧识别显示器的显示图像,与第一表面的显示范围对应的第二表面的至少一部分相对于第一表面对角地设置。

    • In PCM signal recording method and apparatus using rotary heads for converting two channels of autio PCM signals each consisting of 12-bit words to a data consisting of 8-bit words and recording the converted data, there is provided means for converting the PCM signals to two data each consisting of eight high order bits of each of two words of the PCM signals, and an 8-bit data consisting of the remaining four low order bits of the respective words. The converted PCM data are recorded on a record tape in a format such that PCM signals having i words/channel which are to be recorded on first and second tracks are divided into a first half and a second half, even data in the first half and odd data in the second half constitute the data to be recorded on the first track, and odd data in the first half and even data in the second half constitute the data to be recorded on the second track.
    • 在使用旋转磁头的PCM信号记录方法和装置中,用于将由12位字组成的两个通道的PCM信号转换为由8位字组成的数据并记录转换的数据,提供了将PCM信号转换为 每个由PCM信号的两个字中的每一个的8个高位构成的两个数据以及由各个字的剩余4个低位组成的8位数据。 经转换的PCM数据以记录在第一和第二磁道上的具有i个字/频道的PCM信号被划分为前半部分和第二半部分的偶数数据的格式被记录在记录磁带上,并且 第二半帧中的奇数数据构成要记录在第一磁道上的数据,上半部分的奇数数据和后半部分的偶数数据构成要记录在第二磁道上的数据。
