    The cleaning of the suction roll was some of the operating problems facing in every paper mill. Unless the clogged suction roll were cleaned, the suction efficiency might be deteriorated. And the suction roll has so many holes that cleaning was almost impossible.
    Machine tenders found that the high pressure jet water would spurt out the stock and other foreign matter, thereby cutting down the time and labour. As it happened, engineers at Asahi Iron Works Company in Osaka, has been thinking about the same problem. Last year, Asahi Iron Works had introduced to Honshu Paper Company and Seiko Isuzu Automobile Company, the “Paper Mill Washer”. Seiko Isuzu is manufacturing a new type high pressure water pump as car washer since for years before.
    Distinctive features of the pump are : two special modified elliptic gears which are arranged and combined properly in the casing, the increased out put considerably per revolution and the highest overall efficiency. Capacity of the pump is up to 10 gallons per minute at 330 r.p.m.. Derivery pressure is up to 250 pound per square inch.
    This pump is used as a main component in the washer. The portable type is extremely easy to handle and to move from place to place. And is very quiet but efficient operation. A cohered pulp is spurt out thoroughly by spraying or jetting. Also it is fitted in removal of strongly cohered pitch, dirty grease and machine oil. Therefore, it is applied to cleaning the machine frame, stock chest, flowbox, etc.

    The standing crops of red pine for our study had been fallen down every month of a year at a certainlocation, and their resin contents were determined.
    The moisture contents of the standing crops were almost invariable through a year, about 60 %, and on the other hand, the resin contents varied with the seasons, low in summer and high in winter. It was found that the resin contents were not correlative with the diameters, heights and annual diameter increments of the wood samples.
