摘要:
In a transmission type screen and other optical devices formed by combining optical sheets such as a Fresnel lens sheet and a lenticular lens sheet, the generation of stray light and defective appearance caused by a friction-reducing agent are prevented. In the optical devices such as a transmission type screen 3 formed by combining a plurality of optical sheets such as a Fresnel lens sheet 1 and a lenticular lens sheet 2, a friction-reducing agent 20 is provided on a surface of at least one of the optical sheets at a thickness of 0.3 nm or more to 10 nm or less. A coating applicator 30 for the friction-reducing agent 20 includes: a transfer roller 31; coating liquid-supplying means 32 for supplying the coating liquid 20 to the transfer roller 31; and scraping means 35 for adjusting the thickness of the coating liquid 20 adhering to the transfer roller 31. In the coating liquid 30, the surface roughness Ra (JIS B 0601-1982) of the transfer roller 31 is set to 0.01 to 1 μm.

摘要:
A fluid-measuring device intermittently drives a heater during a measurement period and receives outputs of the lateral side temperature sensors as lateral side temperature signals upon non-driving whenever the heater stops heating during a measuring period. Then, the fluid-measuring device receives outputs of the lateral side temperature sensors in response to the heating of the heater 4 as lateral side temperature signals upon driving corresponding to the lateral side temperature signals upon non-driving. The fluid-measuring device also receives upstream and downstream side temperature signals outputted from upstream and downstream side temperature sensors corresponding to the lateral side temperature signals upon driving. The fluid-measuring device detects physical properties data of the fluid on the basis of the lateral side temperature signal upon non-driving and the lateral side temperature signal upon driving. The fluid-measuring device corrects the upstream and downstream side temperature signals on the basis of the physical properties data. The fluid-measuring device detects a temperature profile varied owing to the velocity of the fluid on the basis of the corrected upstream and downstream side temperature signals, and calculates the flow rate of the fluid.

The earth pressure in the underground working area is effectively alleviated by injecting high-pressure liquid into a weak ground stratum underlying the ore bed being excavated thereby to enlarge the stress envelope formed around the working face. The liquid injection hole is formed as by drill means to extend from the working face or a neighboring gateway through an intermediate layer into the weak stratum preferably at a point outside of the stress envelope initially formed.
