A space division multiplexed (SDM) transmission system that includes at least two segments of transmission media in which a spatial assignment of the two segments is different is provided. For example, the SDM transmission may include a first segment of transmission media having a first spatial assignment and a second segment of transmission media having a second spatial assignment, wherein the first spatial assignment differs from the second spatial assignment. An example method obtains an optical signal on a first segment of transmission media having a first spatial assignment and forwards the optical signal on a second segment of transmission media with a different spatial assignment. The transmission media may be a multi-core fiber (MCF), a multi-mode fiber (MMF), a few-mode fiber (FMF), or a ribbon cable comprising nominally uncoupled single-mode fiber (SMF).

In a flip chip type light-emitting element of the present invention, an n type contact electrode 14 is formed on an n layer 11 exposed in a comb-tooth shape, a light transmission electrode 15 made of an ITO is formed over the entire surface of an upper surface of a p layer 13 and twenty pad electrodes 16 are formed at prescribed intervals on the light transmission electrode 15. The plane form of the pad electrode 16 has four branches 16b protruding in the form of a cross from a circular central part 16a and the adjacent pad electrodes 16 connected to each other by the branches 16b.

A light guide and various vehicular lamp assemblies using the same are presented herein. In one embodiment, the lamp assembly includes a light source, such as an LED module. A light coupler is operable to receive light from the light source, and distribute the light in a first direction. The light guide includes an elongated, curvilinear body with first and second longitudinal end faces, and opposing light-emitting and light-guiding surfaces extending between the two end faces on a respective side of the body. The first end face communicates with the light coupler to receive light therefrom. The light guide body transmits light generated by the light source along the longitudinal expanse thereof. The light-guiding surface includes an array of longitudinally-spaced optical grooves configured to refract light generated by the light source in a second direction. The depth of preselected optical grooves is varied along the length of the light guide.

To provide a slurry for thermal spraying capable of forming a favorable sprayed coating. The present invention provides a slurry for thermal spraying including spray particles including at least one material selected from the group consisting of ceramics, inorganic compounds, cermets, and metals and a dispersion medium. Here, the spray particles have an average particle size of 0.01 μm or more and 10 μm or less and are contained in the slurry for thermal spraying at a proportion of 10% by mass or more and 70% by mass or less. In the slurry for thermal spraying, the spray particles have a zeta potential of −200 mV or more and 200 mV or less.

An object according to the present invention is to provide a catalyst layer for a fuel cell, which prevents the lowering of the performance due to the lack of oxygen in a high current density region and can provide a desired power, even when containing a small amount of catalyst particles. The catalyst layer for a fuel cell has a structure including: an electroconductive carrier made of a secondary particle which is formed by agglomerating a plurality of primary particles; catalyst particles which are dispersed on and carried by the electroconductive carrier; and an ionomer which covers the electroconductive carrier and the catalyst particles, wherein the catalyst particles have the particle quantity in a range of 0.05 mg/cm² to 0.15 mg/cm², the electroconductive carriers have the average secondary particle size in a range of 100 nm to 180 nm, and the ionomer has the film thickness in a range of 6 nm to 16 nm. Thereby, the catalyst layer for a fuel cell can reduce the amount of oxygen per one piece of the secondary particles to inhibit oxygen from concentrating on the surface of the ionomer, and shortens the diffusion distance of oxygen in the ionomer to alleviate a rate-controlled condition by the concentration diffusion process of oxygen in the catalyst layer.

An energy absorbing system is provided to protect vehicle drivers and the like from serious injury which may occur when the vehicle strikes a wall or other rigid structure. The system utilizes a plurality of energy absorbing units having hinged plates with a cushion backing which dampens the impact by swinging in an overlapping fashion. The plates are formed from steel and the cushion is formed with a high density outer polymeric casing and a relatively low density filler within.

A ceiling speaker mountable in a ceiling tile for mounting in a suspended ceiling of a room, includes a central woofer, and at least four surrounding pivoting tweeters that are independently adjustable so as to provide broad flat coverage throughout the room. A crossover network directs low frequency signals to the woofer and high frequency signals to the tweeters and an optional stereo separator circuit directs left and right signals to different pairs of the tweeters. A method for adjusting sound dispersion produced by the ceiling speaker is also disclosed.

An improved method of providing a carbon dispersion coating on surfaces of a substrate in a direct metallization process, wherein the substrate comprises conductive and non-conductive portions. The method comprises the steps of contacting the substrate with the carbon dispersion to coat the substrate with the carbon-containing dispersion and at least one of moving a non-absorbent roller over at least a portion of a substantially planar surface of the substrate to remove excess carbon dispersion from the substantially planar surface of the substrate and passing the substrate through a vacuum extraction chamber to extract excess carbon dispersion remaining on surfaces of the substrate. The method provides cleaner copper surfaces to minimize the microetch requirement and also prevents the carbon dispersion from undesirably redepositing on surfaces of the substrate.

A method for forming the vertically-oriented lens assembly is also disclosed, including: disposing the optical lens (2) on a rigid supporting member (5) of the lens frame (1) so that the optical lens (2) is vertically oriented; applying a force to the optical lens (2) via the tightening screw (8) to make the rigid supports (7) both abut the optical lens (2); adjusting a supporting force provided by the elastic support (4) to the optical lens (2) by the adjusting screw (10); attaching pre-tensioning spring leaf (6) and dispensing an adhesive through bores (3) to fixedly attach the optical lens (2) to the lens frame (1); and attaching an axial stop block (11), allowing high stability and a high surface precision and it can be used in engineering applications.

An automatic braking control device includes a temperature obtaining section for obtaining an index value of a temperature of brake fluid, a collision prediction time calculation section for calculating collision prediction time of a vehicle with an object, a collision determination section for determining whether the collision prediction time is less than or equal to a threshold, and a pressure control section for controlling a start timing of pressurization of the brake fluid when the collision prediction time is less than or equal to the threshold. The pressure control section sets the start timing to a first timing when the index value is a first temperature and to a second timing when the index value is a second temperature higher than the first temperature. Time from determination of the collision determination section to the first timing is shorter than time from the determination to the second timing.
