摘要:
A power supply device accumulates charges generated by a photovoltaic unit. The power supply device includes a first capacitor having a first capacitance, in which the charges generated by the photovoltaic unit are charged; a second capacitor having a second capacitance that is larger than the first capacitance; and a switching unit that switches between a first connection of connecting the photovoltaic unit to the first capacitor and a second connection of connecting the first capacitor to the second capacitor.

A display control unit performs a control of displaying first image information on a display unit. An electric-power supply unit converts thermal energy generated from a body temperature of a user into electric power upon the user contacting the electric-power supply unit, and supplies the electric power to the display control unit. A determination unit determines whether the user is in contact with the electric-power supply unit. When it is determined that the user is not in contact with the electric-power supply unit, the display control unit performs a control of rewriting the first image information displayed on the display unit with second image information.

In an image forming apparatus, a monitoring unit monitors whether a returning factor required to switch an operational state of the apparatus from a power-saving mode to an operating mode is generated, an antenna unit receives external electrical wave, a power generation unit generates electricity from the received electrical wave and supplies the electricity to the monitoring unit, and a controlling unit switches the operational state of the apparatus from the power-saving mode to the operating mode when the monitoring unit detects generation of a returning factor.

A thermoelectric conversion element converts thermal energy of a user into electric power. A holding unit holds the electric power converted by the thermoelectric conversion element, and outputs the electric power. A switching unit switches between a first mode in which electric power is supplied to all units of an image forming apparatus and a second mode in which electric power is supplied to a part of units of the image forming apparatus. When the image forming apparatus is in the second mode, the switching unit switches from the second mode to the first mode upon receiving the electric power output from the holding unit.

In an image forming apparatus, an energy converting unit receives light from an optical source and converts the light into electric power, and an electrical storage unit stores therein the electric power. The energy converting unit is arranged in such a manner that a relative position of the energy converting unit to the optical source is always constant when a reading unit is reading an image.

A heater device includes a heating unit which includes a heating element that generates heat using an induction-heating method. A power supply part supplies a driving current to the heating unit. A first high-frequency component cutoff unit is connected to the power supply part. A switching unit controls the supply of the driving current from the power supply part to the heating unit. A second high-frequency component cutoff unit is connected to the switching unit. And a connection unit connects the first high-frequency component cutoff unit and the second high-frequency component cutoff unit.

Provided is an electrochromic display element including a first substrate, a first electrode over the first substrate, a first electrochromic layer over the first electrode, an electrolyte layer over the first electrochromic layer, a second electrode over the electrolyte layer, and a second substrate over the second electrode. The first electrochromic layer contains tin oxide having an average primary particle diameter of less than 30 nm and an electrochromic compound containing a functional group bindable to the tin oxide. The amount by mole of the electrochromic compound per area of the first electrochromic layer is from 2.0×10−8 mol/cm2 through 2.0×10−7 mol/cm2.
