A hydraulic motor control circuit for use in a device for driving construction equipment, such as shovel loader, which comprises a hydraulic driving motor, a pump for feeding compressed oil to the hydraulic motor and a tank for receiving the compressed oil discharged from the hydraulic motor. The circuit comprises a pilot operation type main valve for controlling the oil flow between the pump and the motor and between the motor and the tank, and a remote control valve for feeding a pilot oil pressure to a pilot chamber of the main valve to turn the main valve to a first position for driving the hydraulic motor. As a feature of this invention, the control circuit further comprises an apparatus for detecting the slanting angle of a downward slope and feeding an oil pressure corresponding to the slanting angle to a second pilot chamber of the main valve. The main valve is adapted to turn from its first position to its second position in which the speed of rotation of the hydraulic motor is confined in accordance with the slanting angle.

The number of signal lines connecting an ultrasonic probe and an ultrasonic diagnostic apparatus main body is reduced or wireless communication is realized by reducing a volume of data of reception signals outputted from plural ultrasonic transducers. The ultrasonic probe includes: plural ultrasonic transducers for transmitting ultrasonic waves according to drive signals and receiving ultrasonic echoes to output reception signals; signal processing units for performing orthogonal detection processing or orthogonal sampling processing on the reception signals to generate two signals representing a complex baseband signal; sampling units for sampling the two signals to generate parallel sample data; a serializing unit for converting the parallel sample data into serial sample data; and a transmitting unit for transmitting the serial sample data.

In a sliding fastener, a fastener element is adhered at a predetermined pitch. The fastener element includes: a close-contact portion; and first and second engaging/disengaging portions which are respectively disposed on the first and the second tape surface sides of the close-contact portion. The close-contact portion has a first close-contact surface and a second close-contact surface which are respectively disposed in one direction and the other direction along the tape length direction. In addition, the pitch is set smaller than a sum of a dimension between the first and the second close-contact surfaces and a dimension between the first and the second close-contact surfaces. As a result, it is possible to make an element row rigid in a line in a more firm manner when a left and right element rows are coupled.

In a method of fastening composite material parts, a first smoothness of a first fastener is measured which is arranged to a first countersink through-hole which is formed in a first fastened work as stacked composite material parts. A second countersink depth is determined based on the first smoothness. A second countersink through hole with a second countersink depth is formed in a second fastened work as the composite material parts. The second fastened work is fastened using the second fastener arranged to the second countersink through-hole.

According to the ultrasonic diagnostic apparatus of the present invention, even when the received signal indicating the ultrasonic echo from the artifact is weak such as when the artifact such as the puncture needle is positioned diagonally to the ultrasonic beam, the received signal can be subjected to the signal processing to identify the position of the artifact and provide high visibility of the artifact to an examiner. Thus, from whichever direction the puncture needle is inserted into the body, the position of the puncture needle can be properly recognized.
