A polycarbonate having a principal chain comprising a repeating unit represented by the formula: ##STR1## (a) a substituted phenoxy group represented by the formula (II) ##STR2## (wherein A is as defined in the appended specification) and (b) p-tert-butyl phenoxy group represented by the formula (III) ##STR3## and/or the phenoxy group represented by the formula (IV) ##STR4## bonded to the terminals thereof in the ratio of (a) 10 to 99 mole percent of the said substituted phenoxy group, and (b) 90 to 1 mole percent of p-tert-butylphenoxy group and/or phenoxy group. This polycarbonate has so high a fluidity and an impact resistance that it is moldable into thin or complex shapes.

The rotational speed of a hydraulic pump motor for a fork lift hydraulic control system is varied basically in accordance with the displacement of spools of manual control valves to allow the pressure supplied to servo cylinders to be smoothly increased. The rotational speed may also be varied in response to additional parameters such as the load to be moved by the servo cylinders, the amount of displacement of the load and the rate at which the spools of the manual control valves are moved to provide improved start free safe load handling characteristics.

An image forming apparatus includes a holding part that holds a detachable constituent component so that the detachable component is displaced to a detachment operating position and primary and secondary mounting completed positions as a result of link with opening/closing operations of an opening/closing part, and a connection part that is provided on the opening/closing part and in which a guide groove is formed which guides a projecting portion provided on the holding part. The guide groove of the connection part includes a narrow portion through which the projecting portion is caused to pass while the detachable constituent component is being displaced from the detachment operating position to the primary or secondary mounting completed position. The narrow portion has a groove width which is narrower than an outer dimension of the projecting portion.

A storage container includes a container body formed with a discharge hole and a filling hole, an opening and closing part opening and closing the discharge hole, a lid member sealing the filling hole, and an operating member having a facing portion facing the filling hole and used to operate the opening and closing part. The operating member moves between a first position where the discharge hole is brought into an opened state, a second position where the discharge hole is brought into a closed state, and where the facing portion is arranged at a position which overlaps the container body, and a third position where the discharge hole is brought into a closed state, and where the facing portion is arranged at a position which does not overlap the container body in the direction of gravity in which the sealing part is attached to the container body.

An image forming apparatus includes: an image forming apparatus main body; and an image forming structure attached/removed in/from the image forming apparatus main body. In a state where the image forming structure is attached in the image forming apparatus main body, a concave part is formed in a position opposite to another concave part formed in an adjacent image forming structure.

In an odd-shaped display whose display area is not rectangular in shape, a defect such as a reduction in the display quality due to the bright line or the like caused by the pixels that are located in a specific portion can be prevented. In an active matrix substrate used as a substrate of such an odd-shaped display in which the distribution area of the pixel electrodes corresponding to the display area has a shape other than rectangular, at least one dummy gate line is formed outside the gate line that is located at the outermost edge on the scanning start side. For peripheral pixels connected to the gate line and the gate line that lies on the scanning end side of the gate line, the gate lines located one row above the respective gate lines are extended on the opposite side of each of the peripheral pixels from the gate line to which the TFT of each of the peripheral pixels is connected. It is preferable that dummy pixels are located on the upper side of the individual peripheral pixels.

An active matrix substrate includes base substrate, gate lines, data lines, thin-film transistors and pixel electrodes. The gate lines are formed on the base substrate. The data lines are formed over the gate lines. Each of the data lines crosses all of the gate lines with an insulating film interposed therebetween. The thin-film transistors are formed over the base substrate. Each of the thin-film transistors is associated with one of the gate lines and operates responsive to a signal on the associated gate line. Each of the pixel electrodes is associated with one of the data lines and one of the thin-film transistors and is electrically connectable to the associated data line by way of the associated thin-film transistor. Each of the pixel electrodes and the associated thin-film transistor are connected together by way of a conductive member. Each of the pixel electrodes crosses one of the gate lines, while the conductive member for the pixel electrode crosses another one of the gate lines that is adjacent to the former gate line.
