Abstract: A displaceable nozzle (8) of an injection steam generator for small appliances, particularly irons or ironing stations, comprising a steam chamber (3) inside a steam generator housing (1) provided with an injection opening (5), is positioned telescopically on a fixed member to define a nozzle chamber (10). This nozzle (8) can be displaced by an inside pressure in the nozzle chamber in a first pressure range in the direction of the injection opening (5) and can be moved back from the injection opening (5) by a restoring force e.g., a restoring spring (12), wherein the inside pressure in the nozzle chamber (10) is lower in second pressure range than in the first pressure range. A drain passage (18) for the nozzle chamber 10 is connected via a valve arrangement (19, 21) to the fixed member (11), so that excess residual water, which exits when the nozzle (18) is moved back from the nozzle chamber (10), does not cause calcification of the nozzle opening (9) and the injection opening (5).

Abstract: A semiconductor integrated circuit related to the present invention comprises a logic circuit, and a mode-switching circuit. The logic circuit has a multiplicity of logic elements, which are driven by a driving voltage applied from a dummy power supply line. The mode-switching circuit, during an active mode, supplies to the dummy power supply line a first electric potential for driving a logic element, and, during a sleep mode, supplies to the dummy power supply line a second electric potential, which is higher than zero volts, and lower than a first electric potential. In a first preferred embodiment, a second electric potential is set to a value such that it is possible to reduce logic circuit OFF leakage current during a sleep mode, and to shorten the time for transitioning from a sleep mode to an active mode.

Abstract: An LED is provided with a p-type semiconductor region in the shape of an island being buried in an n-type semiconductor region from the surface of it, and forms a pn junction at the interface between these n-type region and p-type region. The pn junction has a bottom junction at the bottom of the n-type region and a side junction at the peripheral side face. The bottom junction comprises a first subjunction being deep and constant in junction depth and a second subjunction varying continuously in junction depth. The depth of the second subjunction is shallower than the depth of the first subjunction. The p-type region portion above the second subjunction is thinner in thickness than the p-type region portion above the first subjunction. A light passing through the p-type region portion of the former is less in absorption and more in optical power of the output light. The total power of the output light of the whole LED is increased correspondingly to reduction in thickness of the p-type region.
