  • Patent number: 10437153
    Abstract: A substrate having a surface on which a resist film is formed and that has undergone pattern exposure processing and development processing is conveyed into a chamber and held by a holding plate. The surface of the substrate W held by the holding plate is irradiated with flash light emitted from flash lamps. The spectral distribution of the flash light has a peak in a wavelength range of 200 nm to 300 nm. The spectral distribution of the flash light also shows that the relative intensity at a wavelength of 300 nm is 20% or more higher than that at a wavelength of 500 nm. Since the resist film absorbs ultraviolet rays, the resist film can be selectively heated by irradiating the resist film with flash light that includes a large number of wavelength components in the ultraviolet region.

  • Patent number: 10393406
    Abstract: An electrical water heater adapted for energy management and a method of controlling the consumption of electrical power from the power supply grid of a utility is described. The bottom resistive heating element of the water heater is a dual element resistive heating element which has a high power rated resistive heating element to heat water and a further low power rated resistive heating element. The power rating of the low power resistive heating element is calculated to be lower than the supply grid diversified mean load. A controller has a communication link with a utility which manages the power supply grid. The utility can control the resistive heating elements of the dual element in such a way, and depending on conditions of the grid, to conserve energy and regulate its frequency thereby resulting in a cost saving to the consumer and the utility. The low power rated resistive heating element is also connectable to an alternative power source.

  • Patent number: 8909033
    Abstract: A method is provided for interconnecting a single electrical heating element of a hot water heater to first and second AC electrical power sources. Typically, these first and second AC electrical power sources include a utility provided electrical power source and a renewable power source that generates AC power from DC power. The method includes operating a controller that selectively connects and disconnects the first and second power sources. If sufficient electrical power is available from the renewable power source, the utility provided electrical power source may be disconnected to preferentially utilize renewable energy.

  • Patent number: 8768526
    Abstract: A system for shifting energy demand from on-peak time windows to off-peak time windows by using hot water heater load shifting, while providing the end user with the level of service (i.e., availability of hot water) according to the user's customary use described by service quality criteria. The shift is accomplished by a controller located at the end user establishment and in communication with a central control server. The controller monitors local water heater upper and/or lower temperature and controls upper and/or lower water heater heating elements in accordance with a demand shift process commanded by the central control server. The controller may determine usage and remaining capacity for reporting back to the central control server. A volumetric capacity and usage determination is disclosed. The control server may select water heaters according to use patterns and/or measured capacity.
