Abstract: A PLC system includes a displacement sensor, drives, and a PLC. The PLC system obtains line measurement data including a plurality of pieces of measurement information or 1D information from the displacement sensor and a plurality of pieces of positional information from the drives that are read in accordance with measurement intervals, generates 2D shape data, and generates 2D shape data as 1D arrangement information for every measurement interval from combination line measurement data combining the 1D information and the positional information.

Abstract: A PLC system includes a displacement sensor, drives, and a PLC. The PLC system performs a data obtaining process for obtaining one-dimensional information from the displacement sensor and positional information from the drives in a task with a first constant cycle, and performs a data generation process for generating two-dimensional shape data or three-dimensional shape data based on the obtained measurement data in a task with a second constant cycle, and can set an amount of processing to be performed for one task in the data generation process.

Abstract: A compound speaker system comprising a woofer, a squawker, a tweeter, and a super tweeter. The squawker, the tweeter, and the super tweeter are attached to a plate and the assembly is rotatably positioned within the cone of the woofer. Since the squawker, the tweeter, and the super tweeter are positioned at different distances from the axis of the assembly rotation, it is possible to design the system such that the speaker which reproduces relatively directional sound, such the tweeter or the super tweeter takes an elevated position as compared to the squawker when the assembly is rotated within the woofer cone.

Abstract: A tuning device for a radio receiver is disclosed wherein the manual knob which permits tuning and permits viewing of a radio frequency scale can be pivoted to face the operator directly. The manual knob is rotatably linked to a shaft of a tuning element, such as a variable capacitor or a variable inductance, by a coupling means including at least one universal joint.
