  • Patent number: 8988637
    Abstract: To suppress light leakage at the time of dark state, and to provide a liquid crystal display device whose electrodes in the reflection areas can be formed with high precision. The liquid crystal display device has a reflection area within a pixel unit by corresponding at least to a reflection plate forming part, and the reflection area is driven with a lateral electric field mode and normally-white. A driving electrode for forming an electric field to a liquid crystal layer of the reflection area is formed on the reflection plate via an insulating film by using a non-transparent electric conductor.

    Abstract: An IPS-mode transflective LCD device includes an array of pixels each including a reflective region and a transmissive region. The reflective region operates in a normally-white mode, and the transmissive region operates in a normally-black mode. A first potential is applied to a liquid crystal layer in the reflective region, and a second potential is applied to the liquid crystal layer in the transmissive region. The first and second potential have therebetween an opposite magnitude relationship in each of the pixels.

  • Patent number: 8436967
    Abstract: An IPS-mode transflective LCD device includes an array of pixels each including a reflective region and a transmissive region juxtaposed. The reflective region operates in a normally-white mode, and the transmissive region operates in a normally-black mode. A common data signal is supplied to the reflective region and transmissive region, whereas the common electrode signal in the transmissive region is an inverted signal of the common electrode signal in the reflective region, to thereby obtain similar gray-scale levels.

  • Patent number: 8336326
    Abstract: Provided is a dispenser including an ice-making water tank for storing ice-making water and an auger-type ice-making machine for producing ice chips by freezing the ice-making water in the ice-making water tank. The auger-type ice-making machine includes a refrigeration casing into which the ice-making water is supplied, and the refrigeration casing and the drain pan are connected to each other through the intermediation of an ice-making water drain pipe. The ice-making water in the refrigeration casing is drained at predetermined time points, and the drain pan is washed with the ice-making water thus drained.

  • Patent number: 8286444
    Abstract: Provided is a dispenser in which a wash water discharge opening provided to a drain pan is connected to an external tap water system via a wash water supply path. The wash water supply path is provided with a wash water supply valve for controlling whether or not to supply wash water to the drain pan. Based on delivery information output from a delivery control section for controlling delivery of ice chips, a wash control section in a controller judges whether or not a delivery count of the ice chips has reached a predetermined set count, and, when it is judged that the delivery count has reached the set count, opens the wash water supply valve to perform a wash action.
