Title: Blower for nuclear power generating plant
Inventor: IGARASHI WATARU
IPC: F04D29/10
Filed: 1987-02-18
Abstract: PURPOSE:To prevent a drain from accumulating in a shaft seal casing, by providing a balance pipe to be set in the lowermost part of the shaft seal casing and to be given a gradient descending toward the direction of a blower suction port. CONSTITUTION:A blower constitutes a shaft seal of a shaft seal casing 5 and packings 6, 6', providing a balance pipe 7 which connects a suction port 3 with the lowermost part of the shaft seal casing 5. Since the shaft seal casing 5 generates in its inside always a pressure equal to the suction port 3, inflow fluid into the shaft seal casing 5 is prevented from hanging into a drain, and the fluid, being left as placed in a gas state, passes through the balance pipe 7 being guided to the suction port 3. Accordingly, forming a structure which accumulates no drain in the shaft seal casing 5 during normal operation, the blower 1, which discharges the drain into the blower 1 by a gradient of the balance pipe 7 even in case of the accumulated fluid in the shaft seal casing 5 changing into the drain when the blower 1 is stopped, prevents the drain from accumulating in the shaft seal casing 5.

Title: Manufacture of coloring hot-dip galvanized steel sheet
Inventor: ISHIHARA HARUHIKO
IPC: C23C2/06
Filed: 1988-02-16
Abstract: PURPOSE:To manufacture the title steel sheet in the wide hue range by spraying Zn powder and titanium oxide powder onto the surface of steel sheet in which sticking ratio of hot-dip zinc is prepd. and subjecting the stuck titanium oxide to oxidizing treatment by a heat treatment furnace. CONSTITUTION:Rot-dip zinc is stuck onto the surface of the steel sheet 1 to be hot-dipped through a hot-dip zinc bath 2 to prepare the sticking thickness of hot-dip zinc to the prescribed sticking ratio by a high-pressure gaseous stream from a wiping apparatus 3. Before the solidification of a zinc sticking layer, the mixed powder of Zn powder and TiO powder is blown thereon from a spraying nozzle 5 of a powder blowing apparatus 4. The steel sheet 1 on which the mixed powder is blown is continuously passed through a heat treatment furnace 6 in an oxidizing atmosphere and oxidizes sticking TiO by heating into TiOx (x=1-2) to change its color into the hue in accordance with the conditions. On the other hand, the stuck Zn powder is sufficiently melted and more stably solidifies TiOx to form a surface layer which is hard to peel. By this method, the coloring hot-dip galvanized steel sheet in the wide hue range can be obtd. by an on-line system according to circumstances.

Title: Automatic gain controller
Inventor: OKUDA KOZO
IPC: H04M1/60
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To suppress the unnecessary gain control against the ending-of-word parts and the background noises of voices and also to secure the maximum gain. SOLUTION: It is decided based on the input signal level calculated by a CPU whether the gain control should be executed. If the input signal level is less than threshold Th11, a flag 2 is set at 1 and the gain control is not executed by the CPU. If the input signal level is more than threshold Th12, the flag 2 is set at 0 and the gain control is executed. If the Th11 is equal to or less than the input signal level and also the input signal level is equal to or less than the Th12, it is decided that the input signal level is reduced compared with the value larger than the Th12 as long as the flag is set at 0. Thus, no gain control is executed.  If the flag is set at 1 when the Th11 is equal to or less than the input signal level and also the input signal level is equal to or less than the TH12, it is decided that the input signal level is increased compared with the value smaller than the TH11. Thus, the gain control is executed. Both Th11 and Th12 can also be variably set.

Title: Production of aluminum or aluminum-alloy strip coil or sheet, suitable for alkali treatment
Inventor: MARUYAMA HARUMI
IPC: C23G1/00
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To prevent nonuniform etching in alkali treatment for an aluminum or aluminum-alloy sheet to be annealed as a coil or a laminated body of sheets. SOLUTION: In applying annealing treatment to a cold rolled strip coil or laminated body of cold rolled sheets of aluminum or aluminum alloy, the amount of rolling mill oil remaining on the surface of the strip coil or sheet is regulated to <=1g/m<2> and then annealing treatment is carried out. The regulation of the amount of residual rolling mill oil to the above range is performed, e.g. by means of removal by cleaning with a detergent, evaportation by regulation of temperature at the time of finishing of cold rolling to >=70 deg.C, etc.  By regulation of the amount of residual rotling mill oil to the above range, the amount of rolling mill oil gathering between sheets on the end side of a small-thickness cold rolled sheet coil can be reduced and the amount of hydrogen formed by decomposition at the time of annealing can be reduced and the amount of hydrogen absorption on the end side can be reduced. As a result, the occurrence of nonuniform etching due to the progress of etching at the time of alkali treatment can be inhibited.
