To provide a power supply control mechanism that can switch an operation mode of a device at users desired optional timing while achieving reduction in size and weight of an electronic device. For this reason, the invention disclosed in the present application includes a power supply control unit that includes a detection terminal and controls a power supply from a power source to a driving circuit, a push switch that can be operated by a user, and a signal generation unit that operates with a power supplied from the power source. The push switch can change a voltage to be applied to the detection terminal according to an operation performed by the user. The signal generation unit outputs a detection signal to be applied to the detection terminal, and stops the output of the detection signal when the voltage of the detection terminal satisfies a predetermined condition. The power supply control unit controls the power supply by detecting that the push switch is operated and the detection signal is stopped on the basis of a change in the voltage applied to the detection terminal, thereby switching an operation mode of a device between at least two modes of a normal operation mode and a sleep mode.

The present invention is intended to permit both real-time display of a picture represented by a non-compressed video signal on a television and display of a picture represented by a compressed video signal at any desired time by simultaneously transmitting the compressed video signal and non-compressed video signal via one interface. An STB packetizes a compressed video signal, and multiplexes the compressed video signal and a blanking signal combined with a non-compressed video signal. Thus, both the video signals are transmitted simultaneously. A picture represented by the non-compressed video signal is displayed on a television in real time. The compressed video signal is stored in a storage medium incorporated in the television, read at any users desired time, and decoded so that a picture represented by the compressed video signal can be viewed at the users desired time.

A magnetic recording medium of the present invention is a magnetic recording medium including a non-magnetic substrate; a non-magnetic layer that is formed on one of principal surfaces of the non-magnetic substrate and contains a non-magnetic powder, a binder, and a lubricant; and a magnetic layer that is formed on a principal surface of the non-magnetic layer opposite to the non-magnetic substrate and contains a magnetic powder and a binder. The magnetic powder has an average particle size between 10 nm and 35 nm inclusive. The lubricant is migratable to the magnetic layer and forms a lubricant layer on a surface of the magnetic layer when a pressure is applied to the magnetic layer. When spacing of the surface of the magnetic layer before and after washing the lubricant with n-hexane is measured with a TSA (Tape Spacing Analyzer), the value of the spacing after washing is 3 to 10 nm, and the value of the spacing before washing is 1 to 5 nm smaller than the value of the spacing after washing.

A wireless charging module includes: a power receiver (2) having a power receiving resonant circuit (4) composed of a power receiving coil and a resonant capacitor; and a rechargeable battery (5) to which output power of the power receiver is supplied. A rectification circuit (20) converts, to DC power, AC power generated in the power receiving resonant circuit through electromagnetic induction between a power transmitting coil of a power transmitter (1) and the power receiving coil, so as to charge the rechargeable battery. The wireless charging module further includes: a capacity detection circuit (24) for detecting a remaining capacity of the rechargeable battery; and a power reception controller (25) for controlling an operation of the capacity detection circuit. The power reception controller can operate the capacity detection circuit with switching between a high-accuracy measurement mode and a low-accuracy measurement mode, the high-accuracy measurement mode detecting the remaining capacity with high accuracy, and the low-accuracy measurement mode detecting the remaining capacity with accuracy lower than that of the high-accuracy measurement mode. The capacity detection circuit is operated in the high-accuracy measurement mode in charging of the rechargeable battery and the low-accuracy measurement mode in discharging of the rechargeable battery. Thus, the remaining capacity of the rechargeable battery can be detected effectively in a power saving manner.

According to the present invention, a projection type image display apparatus enables control of a large amount of light masking through a light-masking unit while maintaining a uniform illumination distribution in an area to be illuminated by the illumination light. The apparatus uses two array lenses on which lens cells are arranged in matrix form, where light-masking unit masks the array lens installed on the light source side in their particular area. The light-masking unit adjusts the amount of light emitted from the light source. The light-masking area of lens cells adjacent to lens cells closest to an optical axis is made smaller than the light-masking area of other cells.
