Abstract: A motor control system of a printer of the type wherein a desired slow-up of a print head is effected by making use of the rotation of a stepping motor and printing is performed by the use of the head, which is characterized by a slow-up means for increasing gradually a drive frequency of the stepping motor from the stopped state of the head so as to provide a print speed required for the head to perform a print action thereby to result in a desired drive frequency, and a print processing means for instructing the head to perform printing, wherein the slow-up means effects slow-up over and beyond an inter-character space extending up to a next print character, and the print processing means instructs printing after passed over the inter-character space and even while slow-up is being effected, whereby the print speed can be enhanced while maintaining the quality of print.

Abstract: A mechanical seismic instrument for recording relative horizontal displacements between the base and foundation of base-isolated buildings or other large structures during earthquakes. A rigid tripod-like arm is connected to the base of the structure; on the other end of the arm is a marking stylus. A record plate is connected to the foundation. When base and foundation move relative to one another, the stylus scribes a record trace on the record plate. Arm and record plate are mounted respectively on mounting plates which are connected and covered by a flexible enclosure. Timing marks on the record trace may be made by striking devices which tap against the shank of the stylus.

Abstract: A scratch strain gauge has an annular target removably supported on a first plate, which is fixed to a first area of a structure that is to have its strains recorded. The target, which has a groove in its periphery, is driven by flat springs, supported on a second plate, which is fixed to a second area of the structure and longitudinally spaced from the first area. The plates have an interlocking relationship for temperature compensation. A dust seal cover is disposed over the space between the plates and the target. A door is pivotally mounted on the cover and closes an opening formed between the cover and the first plate and through which the target can be inserted and removed. One of the supports for supporting the target is mounted on the door and engages the bottom of the groove. A resiliently mounted support on the first plate also engages the bottom of the groove as does a third support fixed to the first plate. The opening of the door enables the target to be easily removed.

Abstract: A three-axis instrument for recording peak accelerations in earthquakes and like kinds of shocks. Recording is by scratches made by hard styli on small metal record plates. No power source and no maintenance are required. The seismic recording elements have novel configurations of mass, spring, and lever arm which permit improved combinations of sensitivity and natural frequency for any given magnitude of stylus friction. For example, a sensitivity of 0.25 cm per g with a natural frequency of 32 Hz may be attained, where error due to a stylus frictional force of 70 mg is less than 1 percent of full-scale. Both hydraulic and magnetic dampers are employed. The latter also provide motional electrical signals for use in calibration.
