摘要： An ultrasonic probe characterized in that the junction surfaces of a piezo-electric element and an ultrasonic wave absorbing material are irradiated with corpuscular rays in a vacuum and are then press-adhered together. Therefore, the highly precise junction is accomplished without being exposed to high temperatures, and undesired reflection on the junction surfaces is prevented and reverberation is efficiently absorbed.

摘要： Measurement and a display of a load of digging a blasted ground which can contribute to accurate blasting. The operating direction of the backet of an excavator is detected by pressure switches (15 and 16), and the pressure PB of the bottom chamber 6SB of a backet cyclinder is detected by a pressure sensor (17). A processor (23) calculates the excavation position in accordance with the signals from a boom angle sensor (18), an arm angel sensor (19), a GPS (20) and a magnetic azimuth sensor (21), integrates the pressure PB in the ON-period of the pressure switch (15) and transmits the excavation position and the integrated pressure to a computer (30) through wireless transmitters/receivers (24 and 31). The computer (30) displays the map of the blast area and the blasting positions and superposes the transmitted excavation position on the map with a mark (x) and the transmitted integrated pressure with a figure. It is judged whether the blasting is proper or not by referring to the integrated pressure, and the judgement is utilized for the next blasting.

摘要： A hydraulic control apparatus is provided with a valve device (B), which controls a pressure oil supplied to a hydraulic cylinder (C) from a hydraulic pump (A). The valve device comprises a spool (16) slidably fitted into a valve body (1) and a non-leak valve (27) for controlling communication of an actuator passage (19). The non-leak valve comprises a main valve unit (40) having a seat valve (41) provided in the valve body, and a pilot control unit (60) having a pilot poppet valve (61) provided on an end cover (31). The seat valve is controlled in proportion to an opening of the pilot poppet valve and houses therein a relief valve (55) for preventing overload on the hydraulic cylinder. Accordingly, the non-leak valve achieves a load holding function and an overload relief function, and is arranged in two rows together with a spool of the non-leak valve, whereby the valve device can be made compact.
