Abstract: A video disc reproducing apparatus is provided with a pickup by which the information recorded on a video disc is detected as a variation in electrostatic capacity. The signal output from the pickup is processed so as to generate a control signal proportional to the logarithm of the pickup signal. This control signal is then utilized to control the pressure of the pickup on the video disc. Element functions of the apparatus may be combined such that an automatic gain control device may also serve to generate the logarithmic control signal.
Abstract translation: 视频盘重放装置设置有拾取器，通过该拾取器将记录在视频盘上的信息作为静电容量的变化被检测。 处理从拾取器输出的信号，以产生与拾取信号的对数成比例的控制信号。 然后利用该控制信号来控制视频盘上拾取器的压力。 可以组合装置的元件功能，使得自动增益控制装置也可以用于产生对数控制信号。

CPC classification number: G01L23/222
Abstract: A knocking detecting device for an internal combustion engine including: a casing in the form of an annular member fastened substantially perpendicularly to an outer sidewall of the engine block; a support member made of a vibration-isolating material such as rubber or synthetic resin, and having one end fastened to the casing and the other end projecting a predetermined distance from the outer sidewall of the engine block to a position within a water chamber or a coolant water passage; a pressure-sensitive member including pressure-sensitive surfaces mounted on the projecting end of the support member, facing away from each other and extending perpendicularly to the outer sidewall of the engine block, for detecting as a change in an electrical signal pressure vibrations transmitted as a knocking sound to the pressure-sensitive surfaces through coolant water from the partition when knocking is produced in the combustion chamber; and lead wires for delivering the electrical signal change responsive to the knocking. This device enables effective detection of only the knocking produced in the combustion chamber as the pressure vibrations in the coolant water.
Abstract translation: 一种用于内燃机的爆震检测装置，包括：壳体，其形式为基本上垂直于发动机缸体的外侧壁固定的环形构件; 由诸如橡胶或合成树脂的隔振材料制成的支撑构件，并且其一端紧固到壳体，另一端从发动机缸体的外侧壁凸出预定距离到位于水室内的位置 冷却水通道; 压敏构件，其包括安装在所述支撑构件的突出端上的压敏表面，所述压敏表面相对于彼此远离并垂直于所述发动机缸体的外侧壁延伸，用于检测作为传递的电信号压力振动的变化 在燃烧室中产生爆震时通过来自隔板的冷却剂水对压力敏感表面的敲击声; 以及用于响应于敲击传送电信号变化的导线。 该装置能够有效地检测在燃烧室中产生的爆震作为冷却水中的压力振动。

CPC classification number: G11B5/588 , G11B15/1808
Abstract: A tracking system including positionable elements, rotary video heads mounted on the positionable elements, a control head, a frequency generator attached to a capstan motor, and a displacing pattern generator. The displacing pattern generator includes counters which count the pulses from the frequency generator. The pattern generator is reset by control signals reproduced by the control head, a still pattern generator, and an adding means which adds the output signal from the counters and the output signal from the still pattern generator. The output signal of the displacing pattern generator is amplified and applied to the positionable element. As result, the video head mounted on the positionable element can properly trace on a recorded video track at a normal tape speed or at a different tape speed.
Abstract translation: 包括可定位元件的跟踪系统，安装在可定位元件上的旋转视频头，控制头，连接到主导轴马达的频率发生器和位移图案发生器。 位移模式发生器包括计数来自频率发生器的脉冲的计数器。 模式发生器由控制头再现的控制信号，静止图形发生器，以及将来自计数器的输出信号和来自静止图案发生器的输出信号相加的加法装置复位。 置换图案发生器的输出信号被放大并施加到可定位元件。 结果，安装在可定位元件上的视频头可以以正常的磁带速度或以不同的磁带速度适当地跟踪记录的视频轨道。
