  • Patent number: 10939515
    Abstract: A discharge lamp includes a discharge tube containing electrodes, and base sections. The base sections have terminals for connecting to external power lines, and internal power lines for connecting the terminals to the electrodes within the discharge tube. Information generation devices that generates information to be output to outside are provided within the base sections. Superimposition circuits that superpose the information, generated by the information generation devices, on the internal power lines within the base sections are also provided within the base sections. The information generation devices include sensors and generate information based on output of the sensors. A receiving circuit extracts and receives the information, superposed on the internal power lines, from the external power lines connected to the internal power lines. Thus, information generated on the discharge lamp side can be transmitted to outside with a simple construction.

  • Patent number: 8970127
    Abstract: A lighting circuit according to embodiments includes: a self-hold element connected in series to an AC power source that generates power for lighting an illumination load, together with the illumination load, the self-hold element being configured to control supply of the power provided by the AC power source to the illumination load by the self-hold element being turned on/off; a noise prevention circuit connected in parallel to the self-hold element; and a damping circuit configured to connect a damping resistance to the noise prevention circuit parallely only for a predetermined period from turning-on of the self-hold element, thereby preventing the self-hold element from being repeatedly turned on/off during a period in which the self-hold element is on under normal conditions, due to a transient during power supply.

  • Patent number: 8844367
    Abstract: A measurement unit for tensile or compressive stress can includes a CCD camera for detecting an interference light, the interference light being formed with a measurement beam from a measured region and a reference beam from a reference mirror. A first objective lens can have the reference mirror. An image processing apparatus can measure the three-dimensional shape of the measured region from the position of the first objective lens at which the interference light provides the maximum contrast and can measure the distance between two gauge points on the basis of the three-dimensional shape. When strain is generated on a micromaterial, the strain against the measured tensile stress is measured on the basis of the tensile stress and the distance between the two gauge points.

  • Patent number: 6988935
    Abstract: The present invention is one for providing an apparatus and a method which make it possible to remove a foreign object or matter such as scale attached on an inner surface of a pipe easily for a short period of time by means of simple equipment and manner, and constituted as follows. Specifically, a holder (11) is attached onto an end of a pipe (P), an abrasion assisting member (16) fixed to a tip end of a support arm (15) is inserted into the pipe (P) by use of the holder (11) and stopped at an area (A) where oxide scale (S) is generated in a large amount. Then abrasive is sent with pressure into the pipe (P) by a blast device (14), and thus a flow rate of the abrasive in the scale-abraded area (A) is increased to abrade and remove the oxide scale (S) securely. Moreover, if required, a spiral groove (17) is formed on an outer circumference of the abrasion assisting member (16) to increase centrifugal force of the abrasive.
