摘要:
This invention is to suppress repeated striking noises as generated by a crawler belt (29) when taken up onto a drive sprocket (25) in a polygonally bent shape. A crawler belt support block (34) is fixedly mounted on top of an upper reinforcing plate (19) of a bracket (15) on the side of the drive sprocket. The crawler belt support block (34) includes a skid block (36) with a crawler belt sliding surface (36B) to be held in sliding contact with lower surfaces of respective links (30) of the crawler belt (29) to guide same in a direction tangential of the drive sprocket (25) when the crawler belt (29) is taken up onto the drive sprocket (25). The crawler belt support block suppresses vertical movements as would occur to the crawler belt (29) when taken up onto the drive sprocket (25) in a polygonally bent shape, to reduce the repeated striking noises generated by meshing engagement of bushes (32) of the crawler belt (29) and the drive sprocket (25).

A rear side of an operator's cabin body is resiliently supported by a rubber mount, and a front side of the operator's cabin body is resiliently supported by a spring mount, of which a spring constant is set to be smaller than that of the rubber mount. Accordingly, a vibration transmissibility of pitching transmitted from a revolving frame to the operator's cabin body can be kept small, and pitching is damped by an oil damper which constitutes the rubber mount. Further, bounce and rolling transmitted to the operator's cabin body are converted into pitching for attenuation of vibration.

摘要:
A device for providing a line of illumination in an optical reader, comprises an internally reflecting body having an elliptical reflecting surface joined to a part-cylindrical reflecting surface. A light source is disposed on one focal line of the elliptical surface, and a plate-like light guide has its light-receiving end disposed on the other focal line of the elliptical surface. One of the two focal lines of the elliptical surface is also the center of curvature of the part-cylindrical surface. The internal reflection and re-reflection of the light in the light guide ensures that the line of light emerging from the exit end of the light guide will be of uniform intensity throughout its length.

Windings for electrical inductive apparatus are disclosed which include a plurality of first and second pairs of disc coil sections arranged in a stack. Each of the second pairs of disc coil sections are disposed between the first pairs of disc coil sections. Each of the disc coil sections includes two conductors wound in parallel with each other. Each of the two conductors at the inner ends of each section in the first pair of disc coil sections are connected to each of the two conductors at the inner ends of each section in the second pair of disc coil sections, respectively. One conductor at the outer ends of the two sections in the second pair of disc coil sections is connected to one conductor at the outer ends of the two sections in the first pair of disc coil sections. Each of the three conductors at the outer end of two sections in the second pair of disc coil sections is connected to one of three conductors at the outer end of two sections in the next first pair of disc coil sections, respectively.

A communication terminal includes a receiver for receiving a communication signal including urgent warning information, a current location information retrieving unit that retrieves location information regarding a current location of a user, a storage unit that stores information regarding a registered point specified by the user or a communication system, a processing unit that calculates a distance between the current location and the registered point, in response to receiving by the receiving unit of the communication signal, and an information providing unit that provides to-be-provided information including, at least, the distance to the user.
摘要:
A mobile information terminal that can acquire an optimum placement area for a controllable object, regardless of variability in user's gripping features among individuals. A pressure sensor array acquires a gripping pressure distribution; a gripping pressure logger records time-series changes in gripping pressure at each pressure sensor forming the pressure sensor array; a gripping pressure change point detection unit includes a gripping pressure change amount calculation section that acquires time-series changes in gripping pressure at each pressure sensor and determines whether the change in gripping pressure per unit time exceeds a predetermined value at any pressure sensor; and a placement area acquisition section specifies, when the change in gripping pressure per unit time exceeds the predetermined value at any pressure sensor, an optimum placement area for a controllable object with reference to a position where the change in gripping pressure per unit time exceeds the predetermined value.

Disclosed is a hydraulic system for a hydraulic excavator. The hydraulic system inputs rotary power from a rotary power producing means to a hydraulic pump to produce hydraulic power, and operates an actuator by the hydraulic power. A hydraulic oil drain line from the actuator is branched into a flow rate control line as a line connected to a spool of a flow rate control valve controllable by manipulation of a lever and a power regeneration line as a line connected to a variable displacement motor for converting hydraulic power of discharged hydraulic oil to reusable energy. A regeneration ratio control means is also arranged to control the variable displacement motor such that a flow rate of the power regeneration line satisfies a preset fixed ratio α relative to a flow rate occurred in the flow rate control line by the manipulation of the lever.
摘要:
A mobile information terminal that can authenticate an authorized user by using behavioral features acquired when the user makes small movements in a limited movable range. The mobile information terminal includes a gripping feature sensor that acquires gripping features; a behavioral feature sample acquisition section that acquires time-series data of gripping features in a fiddling session as samples of behavioral features; a switch that puts the mobile information terminal into either a learning mode or an authentication mode; a template learning section that learns an authentication template by using the samples of behavioral features when in the learning mode; an authentication section that authenticates the user by comparing the samples of behavioral features with the learned authentication template when in the authentication mode; and an unlock section that unlocks all or some of the functions of the mobile information terminal when the authentication succeeds.
