Abstract: A stroke sensor includes conductor pieces 51 to 57 of a detected body 50 two-dimensionally arranged on a lower surface of a slider 41 in a specified pattern. The lower surface of the slider 41 is divided into four regions corresponding to respective detector units 61 to 64 along a Y-direction. The conductor pieces 51 to 57 are arranged over a specified X-direction extent in the respective regions. The arrangement of the conductor pieces 51 to 57 is set such that the combinations of the conductor pieces 51 to 57 detected by the detector units 60 become different in each and every shift range in the X-direction. This makes it possible to consistently specify the shift range based on the combination of the detector units 61 to 64 staying in the detected state.

Abstract: In an insulation type AC-dc converter in which input current from a commercial power supply is converted to obtain insulated direct current, the overall efficiency is raised and the structure is simplified. A multi-resonance type half-bridge DC-DC converter having an insulation transformer T is used as a first converter, and a boosting chopper circuit for power factor improvement is used as a second converter. Hence through multi-resonance operation, increases in losses can be suppressed even when the switching frequency is raised, and because a half-bridge circuit is used, switching elements and similar with lower voltage ratings can be employed, whereby overall efficiency can be increased.
Abstract: A system manages communications between a provider and a requestor in a distributed network. A requestor is implemented on a computing device and provides a stay online binding. The stay online binding identifies a binding that is desired by the requestor. A provider is implemented on a computing device and provides a binding. The provider receives the stay online binding from the requestor and continues providing the binding because the provider became aware of the stay online binding.
Abstract: The network system includes a controller and a plurality of terminals. The controller repeats transmitting a request signal indicative of a predetermined probability. Upon receiving the request signal, the terminal sends, at the probability indicated by the request signal, a response signal including the identification information uniquely allocated to the terminal. Upon receiving the response signal, the controller sends a notification signal with reference to the identification information included in the response signal. The terminal judges whether or not a response has been completed, on the basis of the received notification signal. The terminal sends no response signal in response to receiving the request signal once after judging that the response has been completed. The controller prepares the next request signal indicative of the probability not less than that indicated by the previous request signal.

The well layer 6a is formed of AlcGadIn(1-c-d)N (0<c<1, c<a, 0<d<1, 1?c?d>0), and contains a second impurity at a concentration of B equal to or greater than zero. In the nitride semi-conductor light emitting device of the present invention, the concentration of A is larger than that of B, in order that the barrier layer 6b has a concentration of oxygen smaller than that in the well layer 6a.

Abstract: An organic EL element (1) is formed by laminating two emitting layers (5, 7) between an anode (3) and a cathode (9) with a hole transporting non-emitting layer (6) being interposed between the two emitting layers (5, 7).

Moreover, it is difficult for holes to reach an electron transport layer (8), so that the electron transport layer (8) is not deteriorated, and the organic EL element (1) can thereby have a long life.
