A measurement probe of the present disclosure that scans a surface of a measurement object to measure a three-dimensional shape or the like of the surface of the measurement object includes a first movable portion having a stylus, a second movable portion that is connected to the first movable portion to be movable in a Z direction, a third movable portion that is connected to the second movable portion to be movable in the Z direction, a first position measurer that measures a first position of the first movable portion in the Z direction, a second position measurer that measures a second position of the second movable portion in the Z direction, and a third position measurer that measures a third position of the third movable portion in the Z direction. A first relative position is calculated based on the first position and the second position. A second relative position is calculated based on the first position and the third position. The first relative position of the second movable portion with respect to the first movable portion in the Z direction and the second relative position of the third movable portion with respect to the first movable portion in the Z direction are maintained constant.

A printing unit includes a plurality of ink jet parts and an X-axis linear motion mechanism that moves each of the plurality of ink jet parts in the same main scanning direction. The X-axis linear motion mechanism moves the ink jet part involved in printing the workpiece among the plurality of ink jet parts so as to face the surface of the workpiece and moves the remaining ink jet part on the one X-axis linear motion mechanism so as to retreat from the surface of the workpiece. As a result, a printing apparatus that is capable of printing accurately onto the workpiece having a three-dimensional curved surface is provided.

Printing apparatus

A digital data demodulator which can reduce a loss of decodable digital data, and increase capability of reproducing digital data inputted through a transmission line even when an error occurs in the transmission line. In the digital data demodulator, a specific pattern detector () detects a specific pattern to be included in a modulation code, from a bit string inputted through a transmission line (). A modulation code identifying unit () generates a demodulation data strobe signal () according to a phase of the modulation code including the specific pattern. An error corrector () samples demodulation data () in response to the demodulation data strobe signal () and reproduces the data to the original digital data.

In a mounting method for mounting a bump-equipped electronic componentwith a plurality of metallic bumpson a substratewith a plurality of electrodesduring the process of connecting the metallic bumpsto the electrodesby aligning the metallic bumps with the electrodeswith thermosetting resinintervening between the electronic componentand substrateand by pressing the electronic componentto the substratewhile exerting ultrasonic oscillation, heat and applied pressure on the electronic componentall of the metallic bumpsare brought into contact with the electrodes so that they are electrically connected to each other, and when some of the metallic bumps are metallic-bonded to the electrodes, ultrasonic oscillation is stopped. Thus, it is possible to prevent occurrence of damage owing to the excessive exertion of ultrasonic oscillation on the metallic bumps which have precedently started their metallic-bonding.
