摘要： PURPOSE:To thin and shorten the cured end of an endoscope by integrating the carrier of a semiconductor chip with a cable connecting circuit board to extend it in one direction, and providing a cable connecting terminal to the portion. CONSTITUTION:Bonding pads are aligned on the long side of a CCD chip 4, conductor patterns 2 which are used also as the pads are provided oppositely on a chip carrier 1, and a cable connecting terminal is formed at the extended end. A left side pattern is crept to the back surface of the carrier 1, and has a similar terminal 3. The chip 4 is wired by wirings 5, and a cable 6 is soldered at 6' to the terminal 3. When the cable connecting terminal portion is extended perpendicularly to the arranging direction of the pads, the width of the CCD can be minimized, and when the terminals 3 are alternately formed, soldering work can be simplified. According to this construction, the connection of the carrier to a circuit board becomes unnecessary to shorten the length of the chip to thin and shorten the cured end 9 of an endoscope, thereby alleviating the pain of a patient.

摘要： PROBLEM TO BE SOLVED: To provide a method for simply joining a metallic member and a ceramic member with a solder while suppressing the generation of deformation or crack and a soldered super sonic sensor having excellent acoustic property. SOLUTION: In the soldering method, a Cu layer is formed on the surface of a joining member 2 and is heat-treated so that the surface area of a joining part 4, where a Cu-Sn compound layer 3 formed by a reaction of Cu with the solder is in contact with the joining member 2, becomes 30-80% of full surface area of the boundary. In the supersonic sensor, the area ratio of the joining part, where the Cu-Sn compound layer is in contact with a piezoelectric vibrator or a front plate, becomes 30-80% of the whole boundary in the joining part of the piezoelectric vibrator and the front plate with the solder and the residual stress is reduced.

摘要： PURPOSE: To provide an ink jet recorder which can record at a high speed with high image quality. CONSTITUTION: A driving circuit 106 is so controlled at the applying time of a drive signal to a piezoelectric element 101 as to vary the number of ink droplets discharged from the liquid surface of a liquid ink 109 in response to the gradation level of an image recorded on a recording medium. An ultrasonic wave radiated from a piezoelectric element array 101 is converged in an array direction in response to the application of the signal, incident to an acoustic lens 107 via an acoustic matching layer 105, converged in the direction perpendicular to the array direction, and converged in a point state near the ink liquid level. An ink meniscus 111 is formed by the pressure (radial pressure) generated by the converted wave near the ink liquid level, an ink droplet responsive to the applying time is discharged from the end, and stuck to the discharged ink droplet recording medium.

摘要： PURPOSE:To exactly irradiate only a calculus without executing erroneous irradiation to an air part by emitting an ultrasonic wave of lower pressure than the shock wave to the inside of the body and converting a reflected wave to an electric signal, deciding a phase of a reflected wave signal, and emitting the shock wave only at the time of a phase from the calculus. CONSTITUTION:A shock wave generator 10 uses a piezoelectric ceramics vibrator 13 being a piezoelectric element, and by a pulser 24, a power source circuit 25 and and irradiation control circuit 28, the vibrator concerned 13 is driven by a lower voltage than the time of generation of a shock wave, an ultrasonic wave of lower pressure than the shock wave is emitted to the inside of the body of a patient, and by receiving a reflected wave through said vibrator 13 and converting it to an electric signal, a reflected wave signal is obtained. Subsequently, a phase of the obtained reflected wave signal is decided by a phase deciding circuit 27, and only when its phase is a phase of the reflected wave signal from a calculus 19, the vibrator 13 is driven by a high voltage and the shock wave is emitted. In such a way, by executing the control in accordance with a result of decision, the shock wave is emitted only to the calculus 19, and is not emitted to air. Accordingly, a pain given to the patient is reduced, and damage of a normal tissue caused by erroneous irradiation of the shock wave is also prevented in advance.
