摘要:
An adjustable lumbar support device for a seat having a lumbar support panel arranged in the backrest of the seat. The lumbar support panel is movable in a forward direction and rearward direction by a spring member. The spring member has a base end portion in contact with the back of the lumbar support panel and terminal ends pivotably connected to a bracket mounted in the backrest of the seat. A threaded shaft axially displaces a holding bracket near the terminal ends of the spring member when the threaded shaft is rotated either manually or by an electric motor. The rotation of the threaded shaft axially displaces the holding bracket which pivots the spring member to move the lumbar support panel forwardly or rearwardly.
摘要:
Magnetic attracting means, especially a permanent magnet, is disposed in a high pressure feed water heater drain pipe line or air separator water tank of feed water and condensed water systems in a thermoelectric power plant. By adoption of this arrangement, iron oxides contained in water in the feed water and condensed water systems can effectively be attracted and removed by this magnetic attracting means.

摘要:
A radio communication system whereby a range is enabled and communication control and quality can be ideally maintained even if the communication distance changes. The transmitting apparatus has a transmitting unit that repeatedly transmits one data packet; a receiving unit that repeatedly receives a response packet; an integrating unit that integrates a repeatedly received response packet; and a determining unit that determines, by use of a result of the integration, whether the received response packet is correct. The receiving apparatus has a receiving unit that repeatedly receives a data packet; an integrating unit that integrates a repeatedly received data packet; a determining unit that determines, by use of a result of the integration, whether the received data packet is correct; and a transmitting unit that repeatedly transmits the response packet when determination is made that the received data packet is correct.
摘要:
Provided is a light source device including a light guide panel which has a first inner reflecting surface and a second inner reflecting surface opposing each other, a first light source which irradiates first illuminating light from a lateral direction to the light guide panel, a second light source which is arranged opposite a side on which the second inner reflecting surface is formed on the light guiding panel, and which irradiates second illuminating light to the second inner reflecting surface, and an optical member which is arranged between the light guide panel and the second light source, and which reduces intensity of incident light, wherein a plurality of scattering areas are provided on the second inner reflecting surface which scatter and emit the first illuminating light from the first inner reflecting surface to outside of the light guide panel.
