Title: Pump unit for oil-supply device
Inventor: OTAKI TSUTOMU
IPC: B67D7/66
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To prevent vibration and noise caused by the pulsating motion of a pump without increase of the weight, by providing a pumping part in a main body and forming a volute part installing a volute chamber and a filter part adjacent to the volute part so as to make cylindrical bodies and providing ribs in the filter part. SOLUTION: The upper end of the flow passage forming in the passage extending upward from a pump part 33 installed in the main body 30 of a pumping unit reaches the cylindrical volute part 36 forming a volute chamber. A cylindrical filter part 37 installed adjacently to the volute part 36 in the horizontal direction to contain the filter in the inside is reinforced by ribs R. A bypass valve part 39 containing a bypass valve connecting the filter chamber in the filter part 37 and the passage 7 at the pump inlet side, is a screw-in type and it is installed between the pump part 33 in the main body 30 and the filter part 37. Since pulsatory motions are not generated even if the wall is thin, owing to the ribs provided in the filter particularly having a large radius, the material can be reduced and a sturdy pumping part without pulsation can be obtained.

Title: Ink supply circuit of printing head
Inventor: RIYUTSUKU RENIYOO
IPC: F04B17/00
Filed: 1995-06-13
Abstract: PURPOSE: To reduce the size of a printer, through cooperation of an assembly comprising a variable volume chamber and a valve and an assembly for constituting an ink and solvent reservoir of a constricted part and a variable volume chamber which drives with an eccentric wheel having a pressure sensor being coupled through a valve. CONSTITUTION: Variable volume chambers 1, 23 detect the volume periodically through an eccentric wheel 3 coupled with a motor 4 rotating at a constant speed. The rotation cycle includes a stop interval required for static pressure measurement through a pressure sensor 5 at every revolution. When a jet 21 is delivered by opening a valve 19, although the volume of ink 34 under pressure of air 180 in the reservoir 18 decreases with time to cause pressure drop, since the pressure is sustained and thereby the volume of ink is sustained, the variable volume chamber 1 and valves 7, 9 function as pump to sample ink 33 in a reservoir 17 and provides it to the reservoir 18. During this interval, pressure is measured by means of the pressure sensor 5, and when the reservoir 17 is empty and the pressure is deficient, the valves 7, 9 and 13 are used sequentially.

Title: Method for removing dross in hot dip alloy plating bath
Inventor: TAKEBAYASHI HIROSHI
IPC: C23C2/12
Filed: 1995-06-14
Abstract: PURPOSE: To efficiently remove a bottom dross generated in manufacturing the Al-Zn hot dip plated steel sheet by adding the dross generated in an Al-Zn hot dipping bath containing Al of the prescribed amount, and floating the dross in the bath to be removed. CONSTITUTION: The dross generated in a hot dipping bath is added to an Al-Zn hot dipping bath containing at least 40wt.% Al (preferably below about 70wt.%), and the dross in the Al-Zn hot dipping bath is floated on the surface of the hot dipping bath, and discharged out of the hot dipping bath. Because the amount of Al and Zn in the hot dipping bath is fluctuated by removing the dross, the removal is performed after the galvanizing work, and when the galvanizing work is re-started, the Al concentration is adjusted to the original value. The amount of the dross is different according to the Al-Zn galvanizing composition. The bottom dross generated in the hot dipping bath is efficiently removed without much labor or dangers in manufacturing the Al-Zn hot dip metal plated steel sheet.
