In order to improve radio characteristic in a transmitter, there are included a &#x394;&#x3a3; modulation means that &#x394;&#x3a3; modulates a given input signal; and a control means that changes parameters of the &#x394;&#x3a3; modulation means in accordance with a given condition.

A holder is rotatably connected to a body . A scribe tool is attached to one end of the holder . A plate spring is fixed to the body , and a receiving plate is fixed to the holder . A piezo-actuator is interposed between the plate spring and the receiving plate . One end of a plate spring having a small spring constant is fixed to the holder . The body is provided with an adjustment screw . When a lower end part of the adjustment screw is protruded, the lower end part presses the plate spring for flexure, thereby generating a resilient force to the plate spring . By this, a rotational force is given to the holder and thus a pressing load directing toward a workpiece is given to the scribe tool

Scribe device

An automatic machining system incorporating all the features of a numerically controlled type machine while eliminating the need for paper tapes. The tool receiving head incorporates means for identifying the moment of contact between tool and work piece, avoiding the need for inputting start position data. Motion control and drive means are provided for X, Y and Z head movement. The novel design provides drilling or punching by insertion of the proper tool in a head adapted to receive either tool. Visual displays provide step by step directions and allow for selection of the machining operation and sequential execution of the machining steps in accordance with inputted data requested by the display. The punching tool operates automatically simply under control of Z axis movement.
