Abstract: An apparatus for cooling thin-webbed H-beam steel includes means for forcibly spray cooling the flanges of the H-beam in intermediate and final hot rolling zones. The cooling is based upon tracking information with respect to predetermined positions along the length of the H-beam. A plurality of flow quantity control blocks are disposed in parallel with each having a three way valve having a water supply side port, a nozzle side port, and a water drain port. A plurality of on-off valves connect the nozzle side port to nozzles in a nozzle group to select nozzles based upon the flange width of the H-beam. A variable throttle mechanism maintains pressure loss at the water drain side equal to pressure loss at the nozzle side. Switching of the three way valve of one flow quantity control block can be carried out without affecting other flow quantity control blocks.

Abstract: The invention is directed to provide a rolling method which enables an enlarged range of reduction ratio in sizing-rolling in the common drive system. The invention provides that when tension applied to rolled material between the upstream and downstream-placed mills is made higher than a value that tension/average resistance to deformation of rolled material is 0.2, the upstream-placed mill is caused to perform force rolling, and when compressive force of the rolled material is made higher than a value that compressive force/average resistance to deformation of rolled material is 0.1, the downstream-placed mill together with the upstream-placed mill are caused to perform tensile rolling in the common drive system. The rolling methods provides a stable rolling in a larger sizing range without decrease of diameter or buckling of rolled material.

Abstract: An automatic document feeder (ADF) for use with with a copier, laser printer or similar image recorder and capable of handling a computer form (CF) document in addition to ordinary documents in the form of sheets. The ADF is selectively operable in either one of two different document transport modes, i.e., it transports initial fives pages of a CF document at a speed per page which is lower than an ordinary speed. While the lower transport speed is selected, the operator has a sufficient time to determine in which direction the CF document neatly folds along the perforation intervening between the first and second pages.

Abstract: A thin-webbed H-beam steel having a web thinner that flanges is produced by forcibly water cooling the outer surface of the flanges during an intermediate hot rolling prior to a final hot rolling by cooling to less than 700.degree. C., interrupting the cooling to return the temperature to greater than 700.degree. C., and repeating the cooling and interrupting in order to refine the microstructure of the surface of the flanges to a predetermined depth from the surface; final-hot rolling the intermediate-hot rolled H-beam steel; and forcibly water cooling the flanges of the final-hot rolled H-beam steel in a manner such that the web does not wave during this forcible water cooling, and such that upon completion of the forcible water cooling, thermal stress, generated in the web during air cooling to room temperature, does not exceed the buckling strength of the web.

Abstract: A heater is adapted to provide heat for heating a room by effecting heat exchange in a heat section which is between combustion and ventilation sections. The heat exchange section comprises a rotary body positioned across the combustion and ventilation sections so as to rotate at that position. The rotary body has air flow passages extending in the same direction as the axis of rotation of the rotary body. The heater can effect heat exchange with an increased efficiency and also can prevent the interior of the room from being abnormally dried.

The reflector is disposed to satisfy two essential conditions. The first essential condition provides that solar radiation reflected from the reflecting surface of the reflector be substantially entirely directed toward the heat collecting surface of the heat collector at the southing time of the winter solstice, while the second essential condition provides that solar radiation incident upon the heat collecting surface of the heat collector be not excessively interrupted by the reflector at the southing time of the summer solstice.
