摘要:
This invention provides various technologies to maximize an air cleaning effect, utilizing photocatalyst materials such as titanium di-oxide.It is possible for the photo catalyst material of the present invention to have an effect of air cleaning not only in day time but also at night, making use of titanium di-oxide as main photocatalyst and platinum as auxiliary catalyst. The former is a photocatalyst material and the latter works to have an effect of having organic compounds adsorbed and decomposed.

There is provided a control apparatus that controls a motor of an electric power steering system to assist a steering effort of an operator. The control apparatus includes a sensor, a parameter computer, a difference computer, a target torque computer, and a motor driver. The parameter computer computes a current value of one of physical parameters of one of constituents of the electric power steering system based on a steering parameter determined by the sensor referring to an equation of motion. The difference computer computes a difference between the current value of the one of the physical parameters computed by the parameter computer and a predetermined value of the one of the physical parameters. The target torque computer computes a target torque of the motor which compensates for the difference between the current value and the predetermined value of the one of the physical parameters.

An LED illumination apparatus includes at least one connector and a lighting drive circuit. The connector is connected to an insertable and removable card-type LED illumination source, which includes multiple LEDs that have been mounted on one surface of a substrate. The lighting drive circuit is electrically connected to the card-type LED illumination source by way of the connector. The card-type LED illumination source preferably includes a metal base substrate and the multiple LEDs that have been mounted on one surface of the metal base substrate. The back surface of the metal base substrate, including no LEDs thereon, thermally contacts with a portion of the illumination apparatus. A feeder terminal to be electrically connected to the connector is provided on the surface of the metal base substrate on which the LEDs are provided.

There is provided a double-face driving silent chain wherein the size of each inner link plate of an exterior driving link train to a back face thereof is set to be equal to or greater than the size of each link plate of an interior driving link train. Thereby, inner side planes of the back face of the inner link plate abut against the both side planes of an interior driving sprocket and guide and prevent the silent chain from engaging with the sprocket in twist. All the link plates, other than the inner link plates of the exterior driving link train, have the same shape when seen from the side and the outermost link plate of the interior driving link train is thin as compared to the other link plates.

A method of constructing underground galleries using a pneumatic transfer system and a stratum disposal method are provided, wherein in constructing a disposal gallery of a stratum disposal site and tunnels such as mountain tunnels or in performing stratum disposal of waste matter, the carrying-out of excavation chips or the like, the carrying-in of materials and equipment or the like and the carrying-in and positioning of waste matter may be effected safely, quickly and reliably at low cost, and the buffer material quality for waste matter may be secured. In construction, an air carrying pipeline (10) is used while extending the air carrying pipeline (10) downward as desired during excavation of a vertical shaft (2) so as to carry out vertical shaft excavation chips (a) to the ground and carry in materials and equipment including vertical shaft spray concrete (b) to the underground site. Alternatively, the vertical shaft itself is used as the air carrying pipeline (10), and by using the air carrying pipeline (10) extending from the vertical shaft (2a) to an underground gallery (3), excavation chips (a) from the underground gallery (3) are carried out to the ground and materials and equipment for the underground gallery are carried in to the underground site. In operation, the air carrying pipeline (10) is used to carry in a carrying container (11) with the waste matter (A) and a buffer material (13) integrated together and stored therein, to the underground site, and the integrated waste matter (A) and buffer material (B) are positioned and buried in a disposal hole (7).

An illumination light source includes four different types of LEDs, namely a blue light-emitting diode 11 emitting blue light, a blue-green light-emitting diode 12 emitting blue-green light, an orange light-emitting diode 13 emitting orange light and a red light-emitting diode 14 emitting red light.
摘要:
A metal base wiring board including: an insulation substrate composed of an upper insulation layer and a lower insulation layer; and a metal base attached to a rear surface of the insulation substrate. In front surfaces of the upper and lower insulation layers, wiring patterns are embedded and connected to each other. The insulation substrate has a plurality of recesses whose bottom faces are exposed areas of the front surface of the lower insulation layer. LED bare chips are mounted on the bottom faces of the recesses so as to be connected to the wiring pattern of the lower insulation layer.
