Title: Charging method and device of aqueous dispersant into storage tank and discharging method and device thereof
Inventor: REHMER GERD
IPC: B67D3/00
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To keep a high quality of an aqueous dispersant contained in a storage tank for a long time and prevent biodegradation and damage of equipment resulting from the biodegradation, by adjusting to keep the delivery opening at almost the water level when charging water by use of such a conduct pipe that the delivery opening follows up the level change near the water face. SOLUTION: A charging pipe 1 of a storage tank 7 is connected to a floating pipe 2 provided with a plurality of rotary joints 3. A float 4 is fitted to the end of the floating pipe 2 and a delivery opening 5 is positioned a little lower than the water level 6. The bottom of the water storage tank 7 is inclined to conduct water to a discharge pipe 8. In this constitution, fresh liquid is charged to the nearby position of the surface on charging it and the liquid held for a long time is taken out from the storage tank 7 through the lower discharge pipe 8 on discharging it. In this way, an additional equipments cost for agitation can be reduced and at the same time, the aqueous dispersant stored in the tank is prevented from excessive aging and the high quality is retained for a long time.

Title: Ac motor for vehicle
Inventor: YOSHIHARA NOBUYUKI
IPC: H02K1/17
Filed: 1994-06-09
Abstract: PURPOSE:To decrease leakage magnetic flux and prevent the destruction of permanent magnets due to a centrifugal force of themselves by locating the permanent magnets outside a rotor and generating magnetic flux without rotating the permanent magnets. CONSTITUTION:Permanent magnets 27a, 28a are fastened to blackets 12, 13 with adaptors 29a, 30a respectively and they are so located that they may face magnetic pole claws 2a, 3a of field iron cores 2, 3 of different polarity. Due to such locations of the permanent magnets, magnetic flux which is generated when current is caused to flow through a field coil 4 is further increased in a stator iron core 10. By this method, the permanent magnets 27a, 28a are not destroyed due to centrifugal forces of themselves because they do not rotate and the magnetic flux increases due to the existence of the permanent magnets and thereby leakage magnetic flux between the magnetic pole claws 2a, 3a is reduced.

Filed: 1988-05-25
Abstract: PURPOSE:To produce a highly stable superconducting element at high reproducibility by sealing a point contact by using glass of low melting point whose melting point is lower than a deterioration temperature of superconductive materials. CONSTITUTION:One surface of a bulk body 1 is polished to a mirror surface 2 and, at the same time, one end of a superconductive fine line 3 is polished to acquire a sharp end 4.

Title: Aqueous composition, aqueous cutting fluid based thereon, their production, and cutting method using this cutting fluid
Inventor: KABURAGI SHINGO
IPC: H01L21/304
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To provide an aq. cutting fluid which does not impact on the work environment or global environment and which not only exhibits a high dispersibility of abrasive grains but also prevents the precipitate from becoming a hard cake. SOLUTION: Abrasive grains G are dispersed in an aq. compsn. which comprises silicic acid colloid particles P stably dispersed in a dispersion medium M contg. a hydrophilic polyhydric alcohol compd. (e.g. ethylene glycol), a lipophilic polyhydric alcohol compd. (e.g. propylene glycol), and water. The dispersion medium M is odorless and nonflammable. Though abrasive grains sediment with time, they do not become in close contact with each other; hence, the resulting precipitate does not become a hard cake and is redispersible and recyclable. Since this aq. cutting fluid inherently has a low viscosity, the decrease in viscosity due to water get mixed in or the increase in viscosity due to cutting scraps get mixed in is slow and the life of the fluid is long. Washing with water of workpieces is possible.  Since org. compds. contained in the dispersion medium M are low-molecular and biodegradable, the waste of the medium M can be treated with activated sludge.

Filed: 1985-06-14
Abstract: PURPOSE:To obtain a heat-responsive pressure-sensitive transfer material showing favorable transfer performance under low impact energy, by incorporating an oil having specified properties into an ink layer. CONSTITUTION:The heat-responsive pressure-sensitive transfer material has the ink layer comprising an oil which is a solid or a highly viscous liquid when being heated. In preservation, a base and the ink layer are firmly adhered to each other, and an offset phenomenon is prevented from occurring. At the time of printing, the adhesion between the base and the ink layer is lowered through a lowering in the viscosity of the oil under heating, so that defective transfer such as transfer of broken characters can be obviated even when printing with low impact energy. The oil has an absolute viscosity of 60-300 cp or is a solid at normal temperature, and has an absolute viscosity at a heating temperature of 40-80 deg.C of 5-50 cp.

Abstract: PURPOSE:To obtain stable pulse-width limitting even when the reference voltage of a converter varies by using a periodical signal wave-form as digital quantity, dividing the reference voltage by resistance circuit and giving the voltage level of control signals an upper limit or a lower limit. CONSTITUTION:A periodical signal wave-forms are generated successively as digital quantities from a function generator 20, and the wave-forms are changed into analog in a D/A converter 22 and modulation signals vm are obtained. On the other hand, the reference voltage Vref of the D/A converter 22 determining the amplitude of modulation signals is potential-divided by a resistance dividing circuit 29, and the voltage level of control signals Vc is given the upper limit VM or the lower limit Vm. Consequently, the pulse width of output signals is given the lower limit or the upper limit. Accordingly, the amplitude of the modulation signals vm does not vary due to the scatter of parts used and a temperature change.
