Title: Shutter for laser beam
Inventor: YOSHIMURA ISAO
IPC: G02B5/08
Filed: 1993-07-13
Abstract: PURPOSE:To provide a shutter for laser beam where the consumption of the power damper is small, and which is miniaturized and lightweight with long life by arranging a lens to diverge the laser beam immediately before the power damper, and making the diverged laser beam incident on the power damper. CONSTITUTION:The laser beam from a laser beam device is reflected by a reflecting mirror 2 and its optical path is bent, and the laser beam is guided to a lens 4. The laser beam incident on the lens 4 is diverged by the lens 4, and the diameter of the laser beam is increased, and the laser beam is made incident on a power damper 3. The density of the intensity of the laser beam incident on the power damper 3 is reduced in inverse proportion to the area of the laser beam, and the local heating of the power damper 3 due to the absorption of the laser beam is reduced. This constitution reduces the danger of breaking the power damper 3.

IPC: G21D3/08
Filed: 1994-07-26
Abstract: PURPOSE:To prevent trip accidents due to the lack of suction pressure by performing the judgment of the steam load drop it its early stages by taking earlier operation signal between a steam load drop detection means and a power drop means as load drop signal. CONSTITUTION:In a power drop detector 11, a rate limiter 21 receives a power signal Ids, limits the output of input decrease rate below a tolerance value and a subtractor 23 subtracts the signal Ids from this output for outputting. A judger 24 gives off output when the output of the subtractor 23 exceeds a predetermined value. The judger and a NOT element 26 prevent instantaneous 0 signal occurrence by turning on the output when the load is gamma% or less and turning off when it is larger. Also, it outputs the output of the judger 24 and the element 26 as signal 11s by way of an AND element 25. Then, the output 2s of a load drop detector 2 and the output 11s is sent through an OR element 30 and a new load drop signal 3es sent to a water level and flowrate controller 3 to control the condensate flowrate. Thus, earlier signal of the signal 2s and 11s can be operated to surely prevent trip accidents.

IPC: G06N7/02
Filed: 1992-07-01
Abstract: PURPOSE:To obtain glossiness in a print by specifying the incorporated quantity and the whiteness of regenerated pulp in the paper being the base paper, thereby using the regenerated pulp. CONSTITUTION:The surface of a side on which one of photographic layers is provided while using the paper as the base paper is coated with a polyolefin resin and the opposite surface is coated with a resin having film forming capability. The base paper contains >=10wt.% regenerated pulp produced from waste paper as the source material in the whole pulp compsn., and the degree of whiteness of the regenerated pulp is specified to >=70. Regenerated pulp has the lower forming ability for bonding fibers compared with vergin pulp but smoothens the surface of paper after paper making.

Thereby, regenerated paper containing regenerated pulp having >=70 whiteness is used to improve this disadvantage.
