摘要： Method of measuring the stress in a thin plate, which is capable of propagating panel waves, by utilizing ultrasonic waves. In this method, ultrasonic waves are introduced into a plate material so that the panel waves occur therein, and the stress in the plate material is measured by utilizing as an evaluation index the rate of variation of the velocity of sound of the panel waves which propagate in the plate material. Thus, the working stress (including the working force and strain) in a plate material having a small thickness and constituting a mechanical device or an electric device can be measured quantitatively and very easily with high accuracy in a very short period of time. Moreover, this method enables real-time measurement of such working stress.

摘要： A tire roller which can enlarge visibility on either of right and left sides of a driver's seat and is convenient in operation. A tire roller comprises a driver's seat provided on a right side of a tire roller body (11), and a getting on and off step (18) provided on the tire roller body (11). In the tire roller, a space (20) for installation of the getting on and off step (18) is defined between a left side of the tire roller body (11) and the driver's seat, and the getting on and off step (18) provided with a plurality of tread boards (21, 22, 23) is mounted in the installation space (20) so as to incline toward a lower portion of the left side from the driver's seat to permit a driver to look down at a left side road surface from the driver's seat through a space above the tread boards (21, 22, 23). Therefore, when the driver looks down at the left side road surface, visibility on the left side is significantly enlarged by enabling the driver to look at a Z point in the vicinity of the tire roller body (11) while it has been possible in conventional tire rollers to look at only a Y point fairly distant from the tire roller body (11).

摘要： A differential pressure PLS between a discharge pressure of a hydraulic pump (2) and a maximum load pressure on a plurality of actuators (3a-3c) is maintained at a target differential pressure DELTA PLSref by a pump capacity control device (5). The target differential pressure DELTA PLSref is modified in accordance with the revolution speed of an engine (1) by conducting to an operation drive unit (32) a differential pressure DELTA Pp across a restriction (50) provided in a discharge passage of a fixed pump (30). An unloading valve (80) comprises first and second auxiliary control pressure chambers (80e, 80f), to which the differential pressure DELTA Pp across the restriction (50) is conducted, and a target differential pressure DELTA Pun for the unloading valve (80) is also modified according to the modification of the target differential pressure DELTA PLSref caused by the operation drive unit (32). Accordingly, a stable load sensing control can be performed without being affected by the engine revolution speed.

摘要： Successive percussion sounds generated by the engagement of a caterpillar chain (29) with a sprocket (25) are reduced. A caterpillar bearing block (34) is provided on an upper reinforcement plate (19) of a bracket (15) on a sprocket side. Lower surfaces of respective links (30), which constitute the caterpillar (29), are in sliding contact with a caterpillar surface (36B) of a skid block (36), which constitutes the caterpillar bearing block (34), whereby the caterpillar (29) is guided to be tangentially wrapped around the sprocket (25). Therefore, vertical movements of the caterpillar (29) when wrapped around the sprocket (25) into a polygonal shape can be suppressed, so that it is possible to reduce successive percussion sounds generated when bushes (32) of the caterpillar (29) engage with the sprocket (25).

摘要： An object of this invention is to provide a metal sheet processing method and a lead frame processing method which are capable of processing a work to an excellent shape finely with a high dimensional accuracy without being influenced by heat input due to the irradiation of a laser beam. According to the present invention, a metal sheet (101) is coated at both surfaces thereof with photoresist films (1) first, and a laser beam (202) is then applied to the metal sheet (101) through the outer surface of the photoresist film (1) so as to form a plurality of discontinuous through bores (3) in rows with joint portions (6) as unprocessed portions left among the through bores (3). The opened portions (2) formed by the laser beam processing of the photoresist film (1) extend continuously to serve as an etching pattern. The surrounding wall portions (6) are then subjected to etching to remove the same and connect together the through bores (3) formed in rows, whereby clearances (303a) of a predetermined shape are formed. Instead of forming the through bores (3) and joint portions (6) in the metal sheet (101), the steps of forming non-through bores (51) in the metal sheet (101) with joint portions (52) left as unprocessed portions in their bottoms, and then subjecting the resultant product to etching may be taken.
