    摘要: A frame assembly including frame members (14, 14', 15, and 15') for supporting a plurality of films (31, 32, 33, and 34) in tension and in spaced relationship and for directing fluid between a pair of the films and receiving the fluid flowing from the pair of films. The frame members include an outer channel (17) and an inner spaced channel (20) with insulation (29) therebetween.

    摘要: The invention comprises a solar collector formed from frame members which support spaced films of radiation absorbing and reflecting capabilities, respectively. The frame further supports an outer pair of films disposed on opposite sides of the inner films. The frame includes inlets and outlets for flow of water between the inner films and flow of air between the outer films and inner films.

    摘要: A disk drive head position encoder is for use in a disk drive having a storage media, a read/write head and an actuator configured to control a position of the head. The position encoder includes a scale having gratings formed by undulations configured to distort light penetrating therethrough. A light source is configured to penetrate the scale and to direct light onto a photodetector, where the photodetector is configured to generate a photodetector signal in response to the light. A processor is coupled to the photodetector and the actuator and configured to determine a head position of the head on the storage media by processing the photodetector signal. In one embodiment, the is constructed from a material having a coefficient of thermal expansion similar to that of said storage media. In another embodiment, the processor includes an analog to digital convertor configured to convert the photodetector signal to a digital signal representative of an amplitude of the photodetector signal, and the processor is configured to determine the head position based at least in part on the digital signal. Advantages of the invention include the ability to accurately position the head on the storage media tracks during prolonged operation of the disk drive. As a result, the recording tracks on the storage media can be made very small and the head can be accurately placed on the recording tracks.

    摘要: Automatic justifying typewriter includes incremental drive means operatively coupled to a printer for effecting controlled horizontal and vertical movement between a printout sheet and the character printing means. The operation of the printer and the drive means may be controlled either by direct keyboard entry or by coded printing operation and spacing operation control signals from a data source, such as, a computer programmed to prearrange the data, assign a preselected horizontal space to each printing character and compute the horizontal space between words for a preselected line length. The coded control signals control the drive means so that after each character is printed, the drive means will advance the character printing means a preselected number of times for that character; and at the end of each line the drive means will index a preselected number of times according to a predetermined setting.
