Title: Dividing device
IPC: G06F7/535
Filed: 1992-03-11
Abstract: PURPOSE:To perform division fast without reference of characteristics of a divisor and a dividend. CONSTITUTION:Three units, i.e., a recovery type divider 1 which performs division fast when the quotient is obtained by several-time operation, a multiplication convergence type divider 2 which performs division fast when not, and a prediction type divider 3 which performs division fast when a predicted value was hit, are combined. A division control circuit 30a monitors the end of each of the dividing processes and employs the result of one divider as a division result when the divider ends its division, outputs it through an output circuit 40a, and also stops other dividing processes.

Title: Method for measuring neutralization of concrete structure
Inventor: FUKUKAWA YOSHIAKI
IPC: G01N33/38
Filed: 1984-05-02
Abstract: PURPOSE:To measure easily neutralization depth of concrete on site by transferring the red coloration occurring in the phenolphthalein reaction arising in the unneutralized part of the concrete to a test piece object inserted into the small hole provided in the concrete. CONSTITUTION:The small hole 2 is drilled down to a required depth from the surface of a concrete structure 1. Compressed air is sent therein to blow away cement powder and further the inside of the small hole is cleaned with fresh water. A sponge-like circular cylindrical object 5 constituting a test piece is inserted into the hole 2 and the phenolphthalein soln. is injected by an injection needle 6 into the object. The object 5 is removed after prescribed time and the distance from the zero point position to the region discolored to a red is measured and is determined as the neutralization depth. The neutralization depth of the structure 1 is thus easily and exactly measured.

Title: Dehumidifier
Inventor: URATANI EIICHI
IPC: B01D53/26
Filed: 1978-07-19
Abstract: PURPOSE: The dehumidifier which is so arranged as to change the water content in compressed air depending upon seasons and maintain its relative humidity always below 100% by using one of two cooling water circulating systems of different cooling water temperatures and cooling and dehumidifying gas by a heat exchanger.  
     CONSTITUTION: The cooling water circulating system B is circulated in the summer season. Compressed air is supplied from inlet 5 and is cooled down to its dew point temperature or under in a heat exchanger 2 and its relative humidity exceeds 100%. The water contents in the compressed air condense and the condensate is drawn out from the drain discharge port 8 of a mist separator 3. At this time, the cooling water temperature obtained through running of a chiller 12 is beforehand set lower by about 5°C than the atmospheric temperature. The water content in the compressed air being sent out from a delivery pipe 7 is high but its relative humidity is sufficiently below 100% and therefore production of water drops in a compressed air using apparatus 14 and pipings does not occur. In the winter season, the cooling water circulating system C is used.

Filed: 1984-05-01
Abstract: PURPOSE:To prevent the trailing end portion of a sheet from remaining at the inlet end of a tray by deflecting a guide groove for guiding a trunnion at a portion facing a transfer member, and shifting an untransferred portion at the deflected portion on the upstream side of sheet transportation, with respect to a transfer portion. CONSTITUTION:When a trunnion 15 of a bin tray 3... is positioned at an untransferred portion 36c of a guide groove, an inlet end of the bin tray is positioned on the upstream side of sheet transportation from a sheet transport downstream side perpendicular tangent V-V of a kick-out rotor 10, so that even if resistance in the transport direction works upon a sheet, the trailing end of a sheet kicked out by the kick-out rotor 10 is reliably placed at a regular position on the upstream side of the inlet end of the bin tray to prevent the back portion of the sheet from remaining at the inlet end of the tray. Furthermore, as it is not necessary to increase the rotating speed of the kick-out rotor 10, a small amount of sheets will be accumulated at a designated regular position without lack of uniformly of the sheets.
