Abstract: In one embodiment of the present invention, a unit circuit of a shift register includes a bootstrap circuit configured with a transistor T1, a transistor T2 and a capacitor, a transistor T3, a transistor T4, and a reset signal generation circuit. By use of two-phase clock signals and whose high level periods do not overlap with each other, the reset signal generation circuit generates a reset signal which is at a high level in a normal state and changes to a low level when an input signal turns into the high level. During a period that the reset signal is at the high level, transistors T3 and T4 perform discharge of a node and pull-down of an output signal. Thus, it is possible to obtain a power-saving shift register that fixes an output signal at a low level in a normal state without allowing a through current to flow therein.

Abstract: In one embodiment of the present invention, a display panel drive circuit includes a plurality of circuit blocks each of which includes former circuits and latter circuits. In each of the circuit blocks in the display panel drive circuit, a signal is transmitted from the former circuits to the latter circuits. Further, the display panel drive circuit includes an inter-block shared wire which allows respective two of the circuit blocks adjacent to each other to be connected to each other. Furthermore, in the display panel drive circuit, the signal of the respective two of the circuit blocks adjacent to each other is transmitted in a time division manner, via the inter-block shared wire. This eliminates the need for an external memory or an arithmetic circuit, thereby making it possible to reduce the area of a circuit in a driver.

With the buffer, it is possible that a consumption current be reduced and a current drive for a load is enhanced.

Abstract: In one embodiment of the present application, during an initial setting period, switches are rendered conductive, so that voltage on a signal line becomes equal to a source voltage, and input voltages of inverters become equal to a logic threshold voltage. During a writing period, other switches are rendered conductive, and the inverters serve as amplifiers. The last-stage inverter is made up of a P-type Tr14, and an N-type Tr15 having a lower current drive capability than the P-type Tr14. At the beginning of the writing period, the voltage on the signal line varies due to current flowing through the P-type Tr14, and therefore the rate of change of the voltage on the signal line does not change by reducing the current drive capability of the N-type Tr15.

Abstract: While an output signal of a flip-flop is inactive in a shift register, NAND circuits of clock pulse extracting sections prevent the performing of conduction switching operation in accordance with periodic level change of clock signals between a logical derivation path for High output and a logical derivation path for Low output, by input of the output signal.

Abstract: In one embodiment of the present invention, a unit circuit of a shift register includes a bootstrap circuit configured with a transistor T1, a transistor T2 and a capacitor, a transistor T3, a transistor T4, and a reset signal generation circuit. By use of two-phase clock signals and whose high level periods do not overlap with each other, the reset signal generation circuit generates a reset signal which is at a high level in a normal state and changes to a low level when an input signal turns into the high level. During a period that the reset signal is at the high level, transistors T3 and T4 perform discharge of a node and pull-down of an output signal. Thus, it is possible to obtain a power-saving shift register that fixes an output signal at a low level in a normal state without allowing a through current to flow therein.

Abstract: In a chair-type massaging machine, when using a leg massaging device or when used as merely a chair or a sofa, it is made possible for a user to take a relaxed posture such as stretching legs forward. The leg massaging device provided in the chair-type massaging machine of the present invention is provided with an advancing and retreating mechanism. The advancing and retreating mechanism allows the leg massaging device to advance and retreat between a zero position in which the treating surface of the leg massaging device hangs down at the front end of the seat section and a second massaging position in which the treating surface is kept substantially horizontal in a massaging mode time.

Abstract: In one embodiment of the present invention, a unit circuit of a shift register includes a bootstrap circuit configured with a transistor T1, a transistor T2 and a capacitor, a transistor T3, a transistor T4, and a reset signal generation circuit. By use of two-phase clock signals whose high level periods do not overlap with each other, the reset signal generation circuit generates a reset signal which is at a high level in a normal state and changes to a low level when an input signal turns into the high level. During a period that the reset signal is at the high level, transistors perform discharge of a node and pull-down of an output signal. Thus, it is possible to obtain a shift register which performs discharge of a node and pull-down of an output signal and achieves a small area and low power consumption without using an output signal from a subsequent circuit.
