摘要： There is to be provided a liquid crystal drive controller with a built-in power supply circuit wherein latch-up is made difficult to arise even if one amplitude level of the segment line drive voltage is set to the ground potential and the levels of other liquid crystal drive voltages are determined accordingly. A semiconductor integrated circuit with a built-in power supply circuit, wherein a negative voltage generated in a power supply circuit is applied to a substrate or a well region as a bias voltage, is provided with a switch for temporarily applying the ground potential to the substrate or well region to be biased with the negative voltage at the time of starting up the power supply circuit.

摘要： By implementing reduction in power of common electrode voltages applied from a power source of a liquid crystal drive device to common electrode interconnects of a liquid crystal display panel, respectively, reduction in power consumption of the liquid crystal display panel as a whole is attained. A VCOM operation waveform in a charging process from a second voltage VCOML to a first voltage VCOMH shows that a charging current Icha represents the sum of a charging current from VCOML to a reference voltage VCI, Icha1=Cp(VCI-VCOML)/Δt, and a charging current from the reference voltage VCI to the first voltage VCOMH, Icha2=Cp(VCOMH−VCI)/Δt. Accordingly, power consumed by Icha1 is the reference voltage VCI×Icha1, and power consumed by Icha2 is VCI×Icha2×2. Meanwhile, a discharging current at a time of discharging from the first voltage VCOMH to the second voltage VCOML is the sum of a discharging current from the first voltage VCOMH to the ground potential GND, Idis1=Cp(VCOMH−GND)/Δt, and a discharging current from the ground potential GND to the second voltage VCOML, Idis2=Cp(GND-VCOML)/Δt. Now, if converted in terms of power consumed at the reference voltage VCI, since Idis1 represents discharge to GND, power consumption thereby becomes zero. Then, consumed power due to the discharging current from the ground potential GND to the second voltage VCOML, Idis2, is VCI×Idis2.
摘要翻译：通过将从液晶驱动装置的电源施加的共电极电压的功率分别实现为液晶显示面板的公共电极互连，能够实现液晶显示面板的整体功耗的降低。从第二电压VCOML到第一电压VCOMH的充电过程中的VCOM操作波形示出充电电流Icha表示从VCOML到参考电压VCI的充电电流之和Icha 1 = Cp（VCI-VCOML）/ Deltat ，以及从参考电压VCI到第一电压VCOMH，Icha 2 = Cp（VCOMH-VCI）/ Deltat的充电电流。因此，Icha1消耗的功率是参考电压VCIxIcha1，Icha2消耗的功率是VCIxIcha 2×2。同时，从第一电压VCOMH向第二电压VCOML放电时的放电电流是从第一电压VCOMH到地电位GND的放电电流Idis 1 = Cp（VCOMH-GND）/ Deltat，和从地电位GND到第二电压VCOML的放电电流Idis 2 = Cp（GND-VCOML）/ Deltat。现在，如果以参考电压VCI消耗的功率转换，由于Idis 1表示放电到GND，因此功耗为零。然后，由于从地电位GND到第二电压VCOML，Idis2的放电电流的消耗功率为VCIxIdis 2。

摘要： An escape glove comprising a glove having a palm portion with a heat-insulating layer thereon, together with a heat- and wear-resistant elastic guide member attached to the palm portion, the elastic guide member having a lateral groove therein proportioned to receive an escape rope therein. The elastic member is located substantially at the center of the heat-insulating sheet layer and permits the user to control relative movement between the rope and the guide member by exerting varying amounts of pressure by his hand movement.
