    • A cover member of an ultrasonic sensor has a first engagement portion and a second engagement portion, which are respectively engaged with a third engagement portion and a fourth engagement portion of a sensor body. The engagement portions are arranged in such a manner that a force applied to the cover member due to an engagement between the first engagement portion and the third engagement portion and a force applied to the cover member due to an engagement between the second engagement portion and the fourth engagement portion respectively have opposite directions to be substantially countervailed when the sensor body is attached to the cover member. Thus, the cover member can be restricted from slanting when the sensor body is fixed to the cover member.
    • 超声波传感器的盖部件具有分别与传感器主体的第三接合部和第四接合部接合的第一接合部和第二接合部。 接合部分被布置成使得由于第一接合部分和第三接合部分之间的接合而施加到盖部件的力和由于第二接合部分和第二接合部分之间的接合而施加到盖部件的力 当传感器主体附接到盖构件时,第四接合部分别具有相反的方向以基本上相反的方式。 因此,当传感器主体固定到盖构件时,可以限制盖构件的倾斜。

    • A character compression-decompression method for printers in which dots are added before compression of a character so as to generate a character in which the same dot pattern continues. The character is compressed and then is stored in a character geernator. Upon printing the character, the compressed character is read from the character generator and is then expanded so as to return the compressed character to the character before compression. The dots added when the character was compressed are removed from the expanded character. Thus, a character which cannot be compressed because the same pattern does not continue therein can be compressed by a simple compression method, and a large number of dot matrix characters can be stored in the character generator.
