A vehicular automotive soil treating machine having a main frame structure provided on an automotive drive means to support thereon a soil feeding stage including at least a soil hopper and an additive hopper for feeding soil and an additive soil improving material, a soil processing stage including a soil processing trough which is internally provided with a mixing device for mixing soil and additive material while being transferred from one to the other end of the soil processing trough, and a processed soil discharging stage including a soil discharging conveyer for transferring processed soil of improved quality in a predetermined direction. The soil processing trough is provided with an inlet opening on the upper side of its fore end portion to receive soil and additive material therethrough, and an outlet opening on the bottom side of its rear end portion to discharge processed soil of improved quality toward the discharging conveyer.

Automotive soil treating machine

A vehicular soil treating machine having a base carrier with a crawler type vehicle drive, an upper rotary body rotatably mounted on the base carrier, and an excavation means mounted on the upper rotary body and equipped with a soil excavating bucket. Provided on the base carrier is an elongated continuous soil processing trough having a predetermined length in the longitudinal direction of the base carrier and internally provided with a tumbling/mixing means for uniformly mixing additive soil improving material into sand and soil which is fed from the excavation means. A soil hopper is provided over one end of the continuous processing trough, and an additive feed means is located behind the soil hopper to feed additive soil improving material to the continuous processing trough.

Pressure sensor

An ultrasonic probe comprising an acoustic lens (20) having a concave lens surface (21) formed on one side of a lens body, and a piezoelectric transducer (23) disposed on the other side of the acoustic lens, ultrasonic waves generated by applying voltage to the piezoelectric transducer being focused through the lens surface to detect the reflected waves of the ultrasonic waves from a sample (26) by the piezoelectric transducer for obtaining information about the surface or interior of the sample. The lens surface (21) of the acoustic lens (20) is defined by an etch profile (15) formed by etching a substrate material (11) which makes up the lens body.

Ultrasonic probe and manufacture method for same

A shock absorbing device for a hydraulic cylinder including a shock absorbing hole formed in an end wall of cylinder, a passageway having a port opening in the shock absorbing hole at its inner peripheral surface and a shock absorbing member attached to the piston and aligned with the shock absorbing hole so that it enters the hole during shock absorbing stroke. During movement of the shock absorbing member, it throttles the flow of fluid in the hole to perform a first stage shock absorption, then throttles the flow of fluid through the port to perform a second stage shock absorption, and at last compresses the fluid in the bottom of the hole to perform a third stage shock absorption.
