摘要： In connection with a display apparatus that is held and swung by an operator to display images of pictures, letters, etc. in space using an afterimage effect, a party situated opposite to the operator is enabled to recognize the images displayed always at the central position of the swing range and with the same dimensions irrespective of the swinging speed and to see the same images displayed even of an asymmetrical pattern irrespective of the directions of the swing of the apparatus. The display apparatus has a transparent protective case covering both side faces, right and left, of an array of LEDs, a measuring unit to measure the cycle time of right and left reciprocating motion, a computing unit to process by computation the measured cycle time, a memory unit to memorize the processed results and a timer circuit unit to control turning the LEDs on and off. This set-up enables a party situated opposite to the operator of the display apparatus to see correct images of letters and pictures displayed always at the center of the swinging width range regardless of the swinging speed.
摘要翻译：结合由操作者握住并摆动的显示装置，使用余像效果在空间中显示图像，字母等的图像，使与位于操作者相对的一方能够识别始终位于中央位置的图像的摆动范围并且具有相同的尺寸，而与摆动速度无关，并且即使是非对称图案也可以看到相同的图像，而与设备的摆动方向无关。显示装置具有透明保护壳，其覆盖LED阵列的左右两侧，用于测量左右往复运动的周期时间的测量单元，计算单元，通过计算处理测量的周期时间，用于存储处理结果的存储单元和用于控制打开和关闭LED的定时器电路单元。该设置使得与显示装置的操作者相对的一方能够看到始终位于摆动宽度范围的中心的字母和图像的正确图像，而与摆动速度无关。

摘要： A rechargeable cordless vacuum cleaner apparatus includes a hand-held cordless vacuum cleaner containing rechargeable batteries, a motor, a fan driven by the motor and a dust-collection filter, and a charging unit containing a power transformer and rectifier diode, with the charging unit being formed with a pocket to removably retain the vacuum cleaner with charging terminals of the charging unit engaged in an electrical receptacle of the vacuum cleaner. Ribs or grooves are formed on an end of the vacuum cleaner which is inserted in the charging unit pocket, and these slidably engage with corresponding grooves or ribs formed on the charging unit, for accurate engagement. A microswitch on the vacuum cleaner acts to disconnect the batteries from a motor drive circuit and connect them to a charging circuit when the vacuum cleaner is inserted in the charging unit.
摘要翻译：一种可充电式无绳电动吸尘器装置，包括可充电电池的手持无绳真空吸尘器，电动机，由电动机驱动的风扇和集尘过滤器，以及包含电力变压器和整流二极管的充电单元，充电单元形成有口袋以可拆卸地保持吸尘器，该充电单元的充电端子接合在真空吸尘器的电插座中。在真空吸尘器的端部形成有肋或槽，该真空吸尘器插入到充电单元袋中，并且与形成在充电单元上的对应的槽或肋可滑动地接合，以便精确地接合。当真空吸尘器插入充电单元时，真空吸尘器上的微动开关用于将电池与电动机驱动电路断开并将其连接到充电电路。
