摘要： A lead screw driven by a motor has a drive nut threadably connected to the lead screw for reciprocation therealong. The drive nut is rotationally restrained thereby limiting its movement along the axis of the lead screw. Three disk members each having an opening through their centers are positioned on the lead screw. The two outer disk members each have at least a pair of bearing members, such as ball bearings, positioned along a diameter of the disk on adjacent sides of the opening. A keeper member is positioned on the lead screw to sandwich the three disk members between the drive nut and the keeper member. Indexing members are positioned on the drive nut and the keeper member to maintain the diameters of the two outer disks, having the bearings mounted therein, orthogonal with respect to each other. A linear motion device is rigidly coupled to the keeper member such that rotary motion of the lead screw is translated to the linear motion device without flexure, eccentricities, or other undesirable movement of the lead screw being transmitted to the linear motion device.

摘要： A system for controlling the intensity of a scanning laser beam used to plot a computer-output microfilm image on an aperture card. The intensity of the beam is controlled by an acousto-optic modulator, which varies the light contained in various components of the modulated output. The first order beam is used for scanning the microfilm because it can be varied from its maximum intensity down to essentially cut-off without requiring large amounts of modulator drive. The intensity control is accomplished in two stages. First, before each scan across the microfilm, a known fraction of the first order beam is split off and sensed for intensity level. This level is directly proportional to the scan beam intensity. The sensed level is then compared to a preset voltage representing the proper exposure operating point for that manufacturer's microfilm characteristics. An error signal is produced by the comparison and is fed into a hold circuit. During this non-microfilm scanning portion of the cycle, the error signal updates the modulator drive level to continuously vary the modulated beam intensity in a way to minimize the error signal, thus, in closed-loop fashion the scan beam intensity is controlled to the proper exposure operating point. Second, as each scan line of the microfilm begins, the hold circuit is switched to "hold" mode so the intensity level sensed before the scan is the level that is held during the subsequent scan. During the scan, pixel data is modulated to the "held" intensity level in order to control the modulation of the scan beam intensity to the operating level. By modulating the beam in a purely binary fashion according to pixel data as it scans across the microfilm, a microfilm image is reproduced.
摘要翻译： 用于控制用于在孔卡上绘制计算机输出的微缩胶片图像的扫描激光束的强度的系统。 光束的强度由声光调制器控制，声光调制器改变调制输出的各种分量中包含的光。 第一级光束用于扫描微缩胶片，因为它可以从其最大强度下降到基本截止，而不需要大量的调制器驱动。 强度控制分两个阶段完成。 首先，在微缩胶片的每次扫描之前，将第一级光束的已知部分分离并感测强度级别。 该电平与扫描光束强度成正比。 然后将感测到的电平与表示该制造商的微缩胶片特性的适当曝光工作点的预设电压进行比较。 通过比较产生误差信号，并将其馈送到保持电路。 在该周期的非微缩胶片扫描部分期间，误差信号更新调制器驱动电平，以便以最小化误差信号的方式连续地改变调制的光束强度，因此以闭环方式将扫描光束强度控制到 适当的曝光作业点。 第二，当微缩胶卷的每个扫描线开始时，保持电路被切换到“保持”模式，使得在扫描之前感测的强度水平是在随后的扫描期间保持的电平。 在扫描期间，将像素数据调制到“保持的”强度水平，以便将扫描光束强度的调制控制到操作水平。 通过在扫描微缩胶片时根据像素数据以纯粹的二进制方式调制光束，再现微缩胶卷图像。

摘要： Line broadening is eliminated in dry heat-developed films by using a development temperature which is higher than the manufacturer-recommended standard temperature, so that a much shorter development time can be used, and masking the edges of the film to prevent exposure thereof. The hot/short development cycle and the masking of the film edges substantially eliminate image smearing caused by emulsion shrinkage and migration.

摘要： A nonoscillatory single step operation of a stepping motor is obtained by using normal driving circuitry and voltage to start the stepping operation in the desired stepping direction and by simultaneously starting a timer which is adjusted in duration to correspond to the time it takes for the rotor to almost reach the null position. At that time an increased voltage, of the same polarity as the normal stepping voltage, is applied, so as to strongly lock the rotor to the null position with minimum oscillation.

摘要： In the preferred embodiment of the invention the jitter in the output signal of a phase-lock loop is minimized by driving a voltage controlled oscillator (VCO) with the average voltage level that appears across a capacitor. The voltage level is maintained by selectively pumping a charge into the capacitor as a function of the deviation of the output signal, from the VCO, from a desired output in a first direction. The charge on the capacitor is allowed to partially bleed off to ground through a variable resistance such that the charge on the capacitor is maintained at levels that cause a slight phase lag in the operation of the voltage controlled oscillator. The phase-locked loop more specifically utilizes an error detector for receiving an incoming digital signal to which the phase-locked loop is to lock and a reference signal corresponding to a divided output signal from the phase-locked loop. The error detector provides signals indicative of the magnitude and the direction of the difference between the incoming digital signal and the reference signal. The difference signals are coupled to a pulse driver circuit for providing pulse charges as a function of the difference signals. A low pass filter having a capacitor receives the pulse charges for charging the capacitor. The low pass filter also incldues means for controllably discharging the capacitor. A voltage controlled oscillator provides an output signal having a phase that is a function of the magnitude of the charge on the capacitor. A divider circuit divides the output signal by selected integers to provide to the error detector the reference signal.
