  • Publication number: 20120050716
    Abstract: The distance measuring device includes a light source (1), a light-receiving sensor (2), a timing controller (5), a distance calculator (6), and a delay controller (8). The timing controller (5) outputs a modulation signal and plural reference timing signals. The modulation signal is a square wave signal having high and low level periods appearing alternately. Each of the high and low level periods has its length randomly selected from integral multiples of a predetermined unit time period. The reference timing signals include a signal having the same waveform as that of the modulation signal and a signal having the same waveform as that of the inverted modulation signal. The light source (1) varies an intensity of the light in concordance with the modulation signal. The delay controller (8) delays the plural reference timing signals by the delay period (Td) to create plural timing signals respectively.

  • Publication number: 20120049865
    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.

  • Patent number: 8125158
    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.

  • Publication number: 20120047226
    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.

  • Publication number: 20120033657
    Abstract: The network system includes a controller and a plurality of terminals. The controller sends a first request signal indicative of a response probability to the plurality of the terminals. Upon receiving the first request signal, each terminal sends a first response signal to the controller at the response probability indicated by the first request signal. The controller determines the total number of the terminals on the basis of the number of the received first response signals and the response probability. The controller determines a limited time period on the basis of the total number of the terminals, and sends a second request signal indicative of the limited time period to the terminals. Upon receiving the second request terminal, each terminal randomly selects a waiting time period from time periods not greater than the limited time period, and sends a second response signal to the controller after a lapse of the waiting time period.

The non-emitting layer (6) includes at least one energy transfer auxiliary material in a hole transporting material. In the organic EL element (1), the energy transfer auxiliary material transfers excitation energy in the non-emitting layer (6) to the emitting layers (5, 7) adjacent to the non-emitting layer (6) effectively, so that luminous efficiency of the emitting layers (5, 7) can be enhanced. 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.
