  • Patent number: 8477585
    Abstract: An optical pickup has an objective lens that is shared for light of three wavelengths. The effective diameter of the light that passes through the objective lens decreases in a sequence of the light of a first wavelength (light for a first optical disk), the light of a second wavelength (light for a second optical disk) and the light of a third wavelength (light for a third optical disk); and the light of the third wavelength is incident on the objective lens in a finite system. The objective lens is provided so that the focal distance of the light of the second wavelength is greater than the focal distance of the light of the first wavelength.

  • Patent number: 8427610
    Abstract: A liquid crystal display device includes a pair of substrates provided opposite to each other, a common electrode provided on one of the pair of substrates, and a pixel electrode provided on the other of the pair of substrates. A vertical alignment type liquid crystal is sealed between the pair of substrates. An alignment film is polymerizable upon irradiation of UV, and is obtained by polymerizing substantially the entire alignment film with a voltage applied between the electrodes after the liquid crystal is sealed between the substrates. A pixel region has areas whose electro-optical characteristics are different from each other because of a difference between applied voltages at the time of polymerization.

  • Publication number: 20120266205
    Abstract: A TV receiver as an electronic device is connected to an adjustment device by an exclusive cable of two transmission lines connected to an HDMI connection terminal. In adjustment mode, a main microcomputer of the TV receiver sends a signal to the adjustment device through a transmission line including an HPD line with an HPD port serving as an output port for the signal, and receives a signal from the adjustment device through a transmission line including a +5V line with a +5V port serving as an input port for the signal. Thus, the microcomputer can perform adjustment processes by receiving product information and various set values from the adjustment device to store them in a memory, and by sending the stored various values to the adjustment device, without providing a UART port, making it possible to reduce manufacturing cost.
