An air-conditioning duct is provided inside a car console box that has an ornamental portion. The duct has an air passage for conducting conditioned air from an air conditioner to the passenger compartment. The air passage is defined by a first wall portion formed by the ornamental portion, a second wall portion opposed to the first wall portion, a third wall portion located between the first and the second wall portions, and a fourth wall portion located between the first and the second wall portions. The fourth wall portion is opposed to the third wall portion. Each wall portion has an inner surface exposed to the interior of the air passage. A pair of boundary lines are defined on the inner surface of the first wall portion at boundaries between the first wall portion and the third and fourth wall portions. A dew condensation suppression portion is provided on the inner surface of the first wall portion between the pair of the boundary lines. A space is defined between the dew condensation suppression portion and each boundary line. When the thickness of the dew condensation suppression portion on the first wall portion is expressed by T (mm), and the sum of the widths of the spaces is expressed by D (mm), the thickness T and the sum D of the widths satisfy the following expression (1). T≧D+2 mm(D>0 mm) (1)

A portable cutting tool includes a base and a tool main body which are inclinably connected such that a saw blade can be projected from a vicinity of an intersection between a side face of the base and a lower face of the base. A parallelism between the saw blade and the side face of the base is made to be able to be adjusted.

A portable cutting tool includes a saw blade for cutting a workpiece, a cutting tool main body having a motor for driving to rotate the saw blade, and a base for guiding the cutting tool main body along a surface of the workpiece. A cut depth of the saw blade projected from a lower face of the base is made to be able to be adjusted by pivoting the cutting tool main body centering on a support shaft connected to the base. The portable cutting tool is provided with a mechanism for fixing the cut depth at a preset position when the cut depth of the saw blade is gradually increased from a minimum cut depth.

A console box of the present invention has a box main body, a pair of sidewalls, and an armrest. The box main body is located between the sidewalls, and the armrest is located above the box main body. Each sidewall has a guide groove extending in the moving direction of the vehicle. The armrest has a pair of engaging pins. Each engaging pin is engaged with and slides along one of the guide grooves. Thus, the armrest smoothly slides along the moving direction of the vehicle.

The present invention relates to a method of driving an active-matrix type of liquid crystal display device that has a plurality of row electrodes to which a scanning signal is applied, a plurality of column electrodes to which a data signal is applied, and a plurality of picture elements (pixels) formed at a plurality of intersections between these row and column electrodes, each of these pixels comprising a liquid crystal layer and a two-terminal element having non-linear resistance characteristics connected in series therewith by means of applying a voltage of a difference signal between a scanning signal and a data signal to the pixels. A compensatory voltage is applied to each pixel immediately before a data write period during which the liquid crystal layer of the pixel is charged with a data charge voltage corresponding to a display gradation. This compensatory voltage is a voltage that charges the liquid crystal layer with a compensatory charge voltage of a polarity opposite to that of the data charge voltage. The relationship between the two voltages is such that when the magnitude of the data charge voltage is large, that of the compensatory charge voltage is small; when the magnitude of the data charge voltage is small, that of the compensatory charge voltage is large. This reduces the occurrence of afterimages that are caused by I-V characteristic shift in a non-linear two-terminal element.

In a method for manufacturing an LDD type semiconductor device, an insulating layer is formed on a semiconductor substrate of a first conductivity type, and an opening is formed in the insulating layer. Then, a first sidewall insulating layer is formed on a sidewall of the insulating layer, and a gate insulating layer is formed on the semiconductor substrate. Then, a gate electrode is buried in the opening. Then, the first sidewall insulating layer is removed, and impurities of a second conductivity type are introduced into the semiconductor substrate to form a low concentration impurity region in the semiconductor substrate. Then, the insulating layer is removed, and a second sidewall insulating layer is formed on a sidewall of the gate electrode. Finally, impurities of the second conductivity type are introduced into the semiconductor substrate to form a high concentration impurity region in the semiconductor substrate.
