摘要:
A pilot-type water discharging/stopping and flow regulating valve device capable of performing both the discharging/stopping of water and the regulation of flow by light operations, and capable of, once the flow is regulated, discharging the water at a pre-regulated specified flow in the next water discharge even if the water is stopped.The pilot type water discharging/stopping and flow regulating valve device has a main valve, a back pressure chamber, an introducing small hole, a pilot channel and a flow regulating mechanism. The flow of the main channel is regulated by advancing and retreating the main valve following the advance/retreat of a pilot valve. The valve device further has a water discharging/stopping switching mechanism that switches between the discharging and stopping of water by advancing and retreating the pilot valve between a water discharge position and a water stop position. Furthermore, the flow regulating mechanism is configured to maintain the flow regulating position of the pilot valve at a previously regulated flow regulating position when the water discharging/stopping switching mechanism causes the pilot valve to perform water discharging operation after causing the pilot valve to perform water stopping operation.

To provide a pulse laser light timing adjusting device capable of easily adjusting pulse laser light timing, a timing adjusting method, and an optical microscope. An optical microscope in accordance with the present invention includes mirror pairs 21 and 31 to generates the first timing adjusting optical beam in which the first pulse laser light ω1 is delayed from the second pulse laser light ω2 and the second timing adjusting optical beam in which the second pulse laser light ω2 is delayed from the first pulse laser light having a first wavelength from the optical beam extracted at the beam samplers 15 and 16, a first detector 23 and a second detector 33 to output a first detection signal and a second detection signal based on a nonlinear optical effect, and timing adjusting means 42 to adjust the timing based on the first detection signal and the second detection signal.
摘要:
An optical fiber (10) includes: a core (11); a first cladding (12) surrounding the core (11) and having a lower refractive index than the core (11); and a second cladding (13) surrounding the first cladding (12) and having a lower refractive index than the first cladding (12). The first cladding (12) is doped with light attenuating dopant so that a concentration of the light attenuating dopant in the first cladding (12) increases from an inner surface of the first cladding (12) toward an outer surface of the first cladding (12).
摘要:
In a hot and cold water mixing device, the slope in a medium-temperature range is gently, and the slopes in a low-temperature range and a high-temperature range are steep. When the target temperature of water mixture is set in the medium-temperature range, a combined biasing force of serially-arranged bias springs acts on a main shaft leftwards, a biasing force of a temperature-sensitive spring acts on the main shaft rightwards, and these biasing forces balance with each other so that the main shaft and valve elements are stopped. When a handle is turned to enter into the high-temperature range exceeding, e.g. 50° C., a slide shaft biases the main shaft leftwards only with the second bias spring. When the handle is turned to enter into the low-temperature range, e.g. below 30° C., the slide shaft biases the main shaft only with the first bias spring leftwards.
