  • Publication number: 20140104504
    Abstract: According to one embodiment, an electronic apparatus includes a housing which includes a front bezel. A display panel and a middle frame are contained in the housing. The middle frame includes a support face which supports an outer circumferential part of the display panel, and is configured to sandwich and hold the outer circumferential part of the display panel between the support face and the front bezel. A reinforcing member is attached to the middle frame. The reinforcing member reinforces the middle frame and is fixed to the front bezel through a connecting member.

  • Patent number: 7701268
    Abstract: In a second system that generates a clock signal that is synchronized with a first system, a control voltage value that controls the second oscillator such that the second system is synchronized with the first system is monitored according to the phase difference between a reference signal that is generated using the output of a first oscillator in the first system and the output of a second oscillator, whereby frequency fluctuation that occurs due to age deterioration of the first oscillator is detected.

  • Patent number: 6801093
    Abstract: A frequency synchronous apparatus includes a switch, frequency division circuit, phase comparison circuit, frequency adjustment and calculation circuit, memory, conversion circuit, and voltage-controlled oscillator. The switch selects either one of a highly stable clock output and a reference clock output in accordance with a mode switching signal. The frequency division circuit divides the frequency of the synchronous clock. The phase comparison circuit detects the phase difference between an output clock from the frequency division circuit and an output clock from the switch, and outputs a phase difference value. The frequency adjustment and calculation circuit performs synchronous control so as to adjust the phase difference value output from the phase comparison circuit to 0, and outputs a synchronous control value at this time. The memory holds the synchronous control value output from the frequency adjustment and calculation circuit.

  • Patent number: 5459764
    Abstract: A clock synchronization system is constituted by first and second clock generating sections. The first and second clock generating units are alternately set in current and spare use modes. The apparatus clock from one clock generating section in the current use mode is supplied to an external circuit. In each clock generating section, a state signal generating section receives a first state signal representing one of the modes, and outputs a second state signal representing a set mode opposite to the mode represented by the first state signal to the other clock generating section. A clock generating section generates a clock synchronized with the network sync signal.
