Title: Robot hand
Inventor: TODOROKI MASAAKI
IPC: B25J15/08
Filed: 1985-06-11
Abstract: PURPOSE:To soften a restriction for arranging a cylinder, to reduce the depth and the height of a whole hand, and also to keep away the cylinder from a high temperature work, by using in common the cylinder for opening and closing a hand lever and opening and closing a finger lever. CONSTITUTION:When a cylinder 26 is brought to an elongating operation, the rotational force of the closing direction works on a finger lever 23 centering around a hinge pin. On the other hand, to the finger lever 23, the energizing force of the opening direction always works by a coil spring, and this energizing force competes with the rotational force of the closing direction of the finger lever 23. Accordingly, when the elongating force of the cylinder 26 is received, first of all, a hand lever 21 executes the closing operation, and both the hand levers 21 hold a work W. In this case, the finger lever 23 remains opened. When the hand lever 21 rotates until it hits against a stopper 33, the pushing force of the cylinder 26 overcomes the energizing force of the coil spring, the finger lever 23 rotates in the closing direction, and the work W is inserted and held from its thickness direction.

Title: Liquid crystal display device
Inventor: KIMURA MUTSUMI
IPC: G02F1/133
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To increase the response speed of a thin film transistor TR liquid crystal display device by correcting a picture signal, which will be applied to a certain picture element, dependently upon another picture signal applied to the picture element till then. SOLUTION: For the period (a turning-on period 14) when a scanning line potential 11 is a potential to set a thin film TR to the turned-on state, the picture signal is transmitted to a picture element electrode potential 12 through a signal line. This picture signal Vsig2' is corrected dependently upon a voltage Vsig2 which will be applied to a liquid crystal phase. Thereafter, the scanning line potential 11 becomes a potential to set the thin film TR to the turned-off state. If the response time of the liquid crystal phase is sufficiently shorter than the period to the next turning-on period 14, namely, a turning-off period 15 in this period (the turning-off period 15), the balanced state is reached in this period. That is, the voltage Vsig2 to be applied to the liquid crystal phase is surely obtained. Consequently, fast response is possible.
