A camera-attached lens device includes a lens barrel, a mount ring, pins, through holes, a positioning ring, and a fixing member. The lens barrel holds a lens system. The mount ring, attached to the lens barrel, has a tubular fitted portion coupling with the camera and a flange portion around the fitted portion. The pins are on the lens barrel and position a central axis of the mount ring with respect to an optical axis. The through holes are on the flange portion. The positioning ring outer diameter is smaller than a hole diameter of the through holes and has an opening where the pins are fitted. The fixing member fixes the positioning ring inside the through holes. The pins are restricted by the opening of the positioning ring fixed by the fixing member when the mount ring is positioned, positioning the lens barrel with respect to the mount ring.

A hydraulic device has a first pump, a second pump, an operating state detector configured and arranged to detect an operating state, a connection switching unit configured and arranged to selectively connect the second pump to either a first hydraulic oil line or a second hydraulic oil line, and a switching controller configured to control, based on the operating state detected by the operating state detector, a switching operation of the connection switching unit. The switching controller is further configured to inhibit the switching operation of the connection of the second pump when the detected operating state is such that at least one of clutches of a multi-stage transmission and a steering device is in a state transition or at least one brake of the steering device is being operated.

A pull-up circuit prevents generation of a leak current if a difference of potentials occurs between a power source voltage of a pull-up circuit (a bus-hold circuit) and an input terminal. A control terminal is provided in the bus-hold circuit. Inputs of the input terminal and the control terminal are input to a NOR gate, and an output of the NOR gate is input to a gate terminal of a first MOSFET that controls coupling between an input terminal and the power source voltage of the bus-hold circuit. A second MOSFET (“control” MOSFET) is provided as a switch that operates by an inverted output of the control terminal. By coupling the first MOSFET and the control MOSFET in series, the coupling between the input terminal and the power source voltage is controlled with a higher precision, thereby preventing generation of a leak current.

A control device controls a hydrostatic transmission vehicle having a hydrostatic transmission with a variable displacement pump and a variable displacement hydraulic motor. The control device is configured to set a set vehicle speed based on a forward/rearward travel command and a gear stage command instructed by an operator, to set an upper limit of the engine speed with respect to the set vehicle speed for limiting the upper limit of the engine speed to a predetermined partial engine speed set to be lower than a high idle engine speed when the set vehicle speed is in a preliminarily set low and intermediate speed range, and to control respective displacements of the variable displacement pump and the variable displacement hydraulic motor based on the set vehicle speed for allowing a vehicle speed to reach the set vehicle speed even when the engine is rotated at the partial engine speed.

A shift control device and a shift control method for a vehicle for reducing shift shock by taking into account the difference in vehicle speeds before and after shifting. In one of the main inventions, the clutch pressure of another clutch (forward clutch) is controlled to match a target vehicle speed to a calculated actual vehicle speed by the time of start of the connecting operation of a selected speed stage clutch. Since such control is performed so that the vehicle speed is caused to match the target vehicle speed, an actual vehicle speed change rate is held within a predetermined range in at least the instant that the connecting operation of the selected speed stage clutch is started. Also, in another one of the main inventions, as shown in FIG. 7, control is performed to adjust the clutch pressure of the other clutch (forward clutch) so that the vehicle speed change rate reaches a predetermined value in the period from when the connecting operation of the selected speed stage clutch is started until when the connecting operation is completed.

The present invention provides a display medium which prevents a decrease in reflectance during storage at high temperatures, and a writing apparatus using the display medium. A photoconductive layer 24, a selective light transmission layer 22, and a liquid crystal layer 20 are laminated between substrates 12 and 14, which have electrodes 16 and 18, respectively, to form a display medium 10. The selective light transmission layer 22 as a color layer is composed of a deionized material. The ion concentration of the selective light transmission layer 22 is controlled to be within a predetermined range.

An invention relating to a control apparatus and a control method for a hydraulically driven cooling fan for reducing the peak pressure produced upon reversing the switch position of a switching valve, without stopping an engine, and without greatly modifying existing hydraulic circuitry or increasing the apparatus cost. In the invention, in the case that a reversing switch has been operated so as to output a reversal processing commencement instruction signal, control is carried out such that, under the condition that the rotational speed of the engine has decreased to not more than a stipulated rotational speed, capacity adjusting means is controlled, so as to reduce the capacity of a hydraulic pump, and thus reduce the fan rotational speed, and then the switch position of the switching valve is reversed.
