  • Patent number: 8767200
    Abstract: A luminous flux branching element includes a transparent base member arranged diagonally to an optical axis and having an incidence plane and an emission plane parallel to each other. Incident light from the incidence plane is split into a main luminous flux emitted from an emission position on the emission plane and a branched luminous flux emitted from a branch position apart from the emission position and having a smaller light quantity than of the main luminous flux. A reflecting member is arranged on the incidence plane to cause the incidence plane to reflect reflected light from the emission plane. A non-coat region in which antireflection-treatment is not performed is formed in a region of the emission plane where the incident light from the incidence plane is reached, and antireflection-treatment is performed in the emission plane excluding the non-coat region and the incidence plane.

  • Publication number: 20140102396
    Abstract: The accuracy in controlling the heating temperature of a glow plug and the reliability of the control operation are improved. An electronic control unit 101 is configured such that a standard applied voltage for glow plugs 50-1 to 50-n is set according to the engine speed and the load conditions of the engine. In addition, a correction coefficient set in advance according to the temperature classification of the mounted glow plugs 50-1 to 50-n is readably stored in the electronic control unit 101 as a correction coefficient map. By multiplying the standard applied voltage by a correction coefficient K read from the correction coefficient map and applying a voltage of the multiplication result to the glow plugs 50-1 to 50-n as a driving voltage through the power circuit 102 to perform driving control, stable and reliable heating temperature control can be realized regardless of variations in the heating temperature characteristics.

  • Publication number: 20140096733
    Abstract: There is provided a new glow plug that can be easily determined as to whether or not it is a new article. An additional circuit 12 formed by connecting a diode 13, a fuse 14, and an adjusting resistor 15 in series in this order is connected in parallel to a heating element 11 of a glow plug 1. The diode 13 is provided so as to have an anode located on the positive electrode side of the heating element 11 and a cathode located on the fuse 14 side. In the case of a unit inspection, by applying a positive voltage for test to a heating element negative electrode connecting portion 3a, it is possible to determine whether or not the glow plug 1 is normal without blowing the fuse 14 before the glow plug 1 is used in a vehicle.

  • Publication number: 20130263156
    Abstract: In order to evaluate the service quality of an application, there are methods which acquire various types of events which occur upon a Web browser upon which an application is operating in order to analyze thereof. On this occasion, if all events are acquired/collected, a load is placed thereby upon the Web browser or a server which records the events. In the present invention, when the Web browser starts the application, a connection is made to an event handler which acquires events related to user operations or application responses. When the event handler detects the occurrence of an event, if the event has not been recorded in the past, the event is recorded as a log. In the case of another event, in case a script has been executed or in case data has been modified, the event is recorded as a log.

  • Publication number: 20130198333
    Abstract: Web browser operation is reproduced without a server being affected by the web operation. A web browser of a client receives a web page, executes an embedded browser-in-formation-acquiring function module and operation-log-acquiring function, generates a log of operations on the web page and application log of the result of executing an application code, and transmits the logs as a user log, together with information related to the web browser, to a content storage and reproduction server device. The content storage and reproduction server converts the received and gathered content and user log, and generates reproduction content and a reproduction user log for reproducing operation in the web browser of an external reproduction device. The content and user log are converted so that web operation can be safely and accurately reproduced with consideration given to the user environment and to the environment during reproduction when the web operation is reproduced.
