A work vehicle includes: a body; a boom which is supported by the body and is turned; a bucket which is supported by a side of the boom opposite to a side of the body and is turned; a boom driving part which turns the boom; a bucket driving part which turns the bucket; a lifting force detector which detects lifting force as force that the boom driving part receives from the boom; and a control device which starts a tilt operation of the bucket when a predetermined condition is established, and ends the tilt operation on the basis of an amount of increase of the lifting force from a time when the tilt operation is started.

A VVT has a movable restriction member and a restriction slot. When the restriction member is in a projected position, the VVT is variable in a restricted range to which the restriction member can be rotatable within the restriction slot. When the restriction member is in a retracted position, the VVT is variable in a range wider than the restricted range. When a condition where the restriction member shall be projected is satisfied, if the variable range of the VVT reaches beyond the restricted range, the device determines that the restriction member is stuck at the retracted position. When a condition where the restriction member shall be retracted is satisfied, if the variable range of the VVT is restricted in the restricted range, the device determines that the restriction member is stuck at the projected position.

A control device for a work machine on a construction vehicle is provided so that a bucket cylinder is stopped at a target position, with high accuracy achieved in a bucket cylinder length, and with chock held down to a low level. A bucket cylinder length detection section refereces a cylinder length detection table on the basis of a boom angle and a bell crank angle, thereby detecting a bucket cylinder length. A bucket attitude control section controls the bucket cylinder length so that a target position will be reached. Feedback control is performed until a set value which is set short of a target value is reached. After the bucket cylinder length reaches the set value, open loop control is performed until the target value is reached.

A polarizing plate for a liquid crystal display is provided and includes a first protective film, a polarizer, a second protective film and a light diffusion layer in order. The light diffusion layer is a layer including a translucent resin and translucent particles having a refractive index different from a refractive index of the translucent resin. The internal haze of the light diffusion layer is 45% to 80%.

A construction vehicle includes an engine, a hydraulic pump driven by the engine, a travel hydraulic motor driven by pressure oil discharged from the hydraulic pump, travel wheels driven by the drive force of the travel hydraulic motor, and a controller. The controller is configured to control an engine speed, displacement of the hydraulic pump, and displacement of the travel hydraulic motor in order to control a vehicle speed and traction force. The controller is further configured to increase a maximum displacement of the travel hydraulic motor as the vehicle speed decreases within a low speed range in which the vehicle speed is equal to or less than a predetermined threshold.

A novel polarizing plate is disclosed. The polarizing plate comprises at least a polarizing film, a pressure-sensitive adhesive layer, and an optical compensation sheet, having an absolute value of Y, defined by the following equation, equal to or smaller than 6.0×10−4: Y=−7.0×105×Cn+4.3×10−13×E−1.34×10−3 where Cn (1/Pa) is photoelastic modulus of said pressure-sensitive adhesive layer and E (Pa) is modulus of elasticity of said optical compensation sheet.

Disclosed is an image forming apparatus, which comprises an image bearing member on which a toner image is formed, a sweep roller for removing residual toner particles from the image bearing member, and a recovery roller for recovering the toner particles from the sweep roller. The recovery roller has a diameter of 10 mm or less, and a surface roughness Rz of 1.6 μm to 6.4 μm.
摘要:
An image display device provided with a panel comprising a substrate comprising glass or resin, a front side laminated body and a back side laminated body, and an optical member adjacent to the back side laminated body, wherein the surface of the optical member going to contact with the back side laminated body has an arithmetic average roughness (Ra) of 6 μm or more. The image display device can maintain excellent display performance under conditions with significant circumstance variations.

A cleaning sheet (1) includes at least one continuous-filament aggregate (10) formed by aggregating and orienting a multitude of continuous filaments (11) substantially in one orientation direction. The continuous filaments (11) are joined by a single first joining line (12) extending continuously in a direction orthogonal to the orientation direction of the continuous filaments (11) and are joined by a plurality of second joining lines (13) extending in the orientation direction. In this way, the continuous filaments (11) in the continuous-filament aggregate (10) are kept in an aggregated state. Preferably, the second joining lines (13) are connected to the first joining line (12).
