摘要:
A traction drive power transmission device, where a lubrication oil can be stably and continuously applied for a long period to portions at which rollers and a shaft are in contact with each other, shortage of the lubrication oil does not occur at the contact portions, the lubrication oil is not wasted, and which does not impair work environment by contaminating floor surface etc. A traction drive power transmission device has at least one drive roller (12a), a follower roller (12b), and a circular cylinder-like shaft (11). The shaft (11) is held between the drive roller (12a) and the follower roller (12b). When the drive roller (12a) is rotated, rotational force by the rotation is transmitted to the shaft (11) to drive it in its axial direction. The device has a lubrication oil-delivering portion (20) with application bodies (22-1, 22-2) for applying a lubrication oil only to portions where the shaft (11) is in contact with the drive roller (12a) and the follower roller (12b).

A ball screw comprises a screw shaft, a hollow cylindrical nut member, balls, a ball returning means and a pair of deflectors. The screw shaft has a helical ball running groove. The nut member has a helical ball running counter-groove facing on the helical ball running groove of the screw shaft, and has a pair of ball-passing holes for connecting inner and outer surfaces of the nut member with each other. The balls are arranged between the ball running groove and the ball running counter-groove. The ball returning means is arranged on the outer surface of the nut member, for connecting the ball-passing holes with each other. The deflectors are disposed so as to be respectively correspondent with the ball-passing holes, for picking up the balls from the ball running groove to transfer the thus picked up balls into the ball-passing hole. Each of the deflectors comprises a ring-shaped base member fitted in an opening end of the nut member, and a ball-picking-up member projected from the base member. The ball-picking-up member is inserted in the ball running counter-groove so as to take a prescribed position of the ball-picking-up member relative to the ball-passing hole.

An apparatus and method for battery state of charge (SOC) estimation can reduce the estimation error in the battery SOC. The apparatus includes a charge/discharge current detection unit, a terminal voltage detection unit, a first estimation unit that estimates a first SOC by integrating the charge/discharge current value, a second estimation unit that estimates an open circuit voltage value from the charge/discharge current value and the terminal voltage value and estimates a second SOC from the open circuit voltage value, a first difference calculation unit that calculates a SOC difference between the first SOC and the second SOC, an error estimation unit that estimates, based on the SOC difference, an error as a state quantity of an error model by using the error model, and a second difference calculation unit that calculates a SOC of the battery by subtracting the error from the first SOC.

There is provided a decoloring device including a decoloring unit, a first sheet conveying unit, a pre-decoloring reading unit, a type determining unit, a second sheet conveying unit, a post-decoloring reading unit, a decoloring success or failure determining unit, and a determination criterion setting unit. The type determining unit determines the type of image on the sheet conveyed to the decoloring unit based on the reading result in the pre-decoloring reading unit. The post-decoloring reading unit reads an image on the sheet after the decoloring, which is conveyed by the second sheet conveying unit. The decoloring success or failure determining unit determines whether or not the decoloring in the decoloring unit is successful based on the reading result in the post-decoloring reading unit. The determination criterion setting unit sets a determination criterion in the decoloring success or failure determining unit, based on the type of image, which is determined by the type determining unit.
