Abstract: A hydrostatic transmission vehicle comprises: a fuel adjustment position detection portion (681) which detects an operation position of a fuel adjustment portion (68); a deceleration operation position detection portion (691) which detects an operation quantity of a deceleration operation portion (69); and a controller (9) which controls a displacement of a hydrostatic transmission (7), and the controller (9) comprises: an operation state judgment portion (91) which judges operation states of the fuel adjustment portion (68) and the deceleration operation portion (69) based on detection values acquired by the fuel adjustment position detection portion (681) and the deceleration operation position detection portion (691); and a displacement control command generation portion (94) which generates a displacement control command which differs depending on a case where an engine revolution number is restricted by the fuel adjustment portion (68) and a case where an engine revolution number is restricted by the dec

Abstract: A program unauthorized-use preventing device (10) includes a storage section (12) for storing various optional operation programs in a machine tool, a display section (16) for displaying first and second program-selection images (14, 22) for selecting a desired operation program, and a processing section (20) for reading out the operation program selected on the first program-selection image from the storage section so as to be in a usable state when a device inherent password (18) is input and reading out the operation program selected on the second program-selection image from the storage section so as to be in a usable state when a machine-tool inherent password (24) is input.

Abstract: A piping structure of a crawler driving hydraulic motor able to reduce a reduction in strength of a vehicle body frame and shorten the exposure length of a hydraulic piping in the exterior of the vehicle body frame, and reduce a damage opportunity due to an external obstacle, etc. Therefore, the hydraulic piping is connected from a hydraulic pump arranged within the vehicle body frame to left-hand and right-hand crawler driving hydraulic motors respectively attached to one-end sides of left-hand and right-hand crawler track frames arranged on left-hand and right-hand outsides of the vehicle body frame. The hydraulic piping extends through a frame rear wall constituting the vehicle body frame, and is taken out to the exterior of the vehicle body frame, and is connected to the left-hand and right-hand crawler driving hydraulic motors.

Abstract: A measuring method capable of automatically analyzing quantitatively the inner state of a disk is provided. Linearly polarized light from a light source enters a retarder to produce a desired elliptically polarized state. The elliptically polarized light is then passed through a half-wave plate to rotate the direction of a principal axis of the ellipse. The light is expanded into two dimensions by lens systems and to obtain planar information, and is further transmitted through a disk substrate so that the birefringence of a specimen, which depends on an inner stress state and a polymer orientation state, changes the phase of the light. The light wave with its phase changed is passed through a polarizer arranged perpendicular to the principal axis of the retarder. The CCD detects the light wave as a light intensity.
