Title: Ink jet printer
Inventor: MAENO FUMIO
IPC: B41J2/165
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To eliminate an ink cartridge to be mounted in a carriage of an ink-jet printer by providing an ink feed part at a position confronting to a nozzle of a printing head which has finished printing and stopped outside a printing area, and connecting to an ink meniscus of an ink feed hole. SOLUTION: An ink feed part 33, an ink feed part 34, a flexible tube 35 and a bracket 36 are filled with ink and connected to an ink inside a cartridge 37. A negative pressure in the ink feed part 33 because of a height difference H or the ink feed part 33 and a surface of the ink inside the cartridge 37 is kept by a recessed meniscus formed at an ink feed hole by a capillary attraction. After a carriage 15 stops, a pinch valve 40 starts to operate to compress the flexible tube 35, whereby the ink in the ink feed part 33 is shut from the ink in the cartridge 37. Thereafter, a PZT of the ink feed part 33 is activated to drive a vibrating plate, whereby the recessed meniscus of the ink feed hole is changed to a projecting meniscus.

Title: Liquid-cooling device
Inventor: TSUDA SHOZO
IPC: F25B39/02
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To prevent liquid from bubbling, improve reliability for cooling capacity, and at the same time miniaturize and make compact a device and reduce its costs by equipping a refrigerating device with a compressor, a condenser, a pressure-reducing mechanism, and a cross-fin-type evaporator and accommodating the cross-fin-type evaporator in a liquid tank. SOLUTION: When liquid to be cooled being heated by a machine tool flows into an upper chamber A of a cross-fin-type evaporator 27 from a liquid inflow port 31, liquid 30 in the chamber A is cooled by the cross-fin-type evaporator 27 and is lowered since its specific gravity is decreased, flows down while being cooled among cross fins 27a, 27a,... along upper/lower directions, and flows into a chamber B at the lower portion of the evaporator 27 as shown by an arrow X. The cold liquid 30 in the chamber B is sucked through a suction strainer 33 by a pump 34 and is supplied to the machine tool through piping 35. In this manner, by accommodating the cross-fin-type evaporator 27 in the liquid tank, the liquid 30 can be effectively cooled without using any stirrer and suppressing bubbling.

Title: Equipment and method for feeding two power supply voltage
Inventor: PURESUTON DEII BURAUN
IPC: H02M3/155
Filed: 1994-01-05
Abstract: PURPOSE: To generate two adjusted output efficiently by using first and second voltage regulators that do not have a transformer. CONSTITUTION: Once the voltage of an output terminal 22 has dropped below a predetermined level, a control device 38 supplies a pulse to a control terminal 56. When a SIGNAL(SG) 40 is high, a switch 54 is on and a current energy is accumulated in an inductor 48 via the inductor 48 and the switch 54. When the SG 40 is low, the switch 54 is off and a current increases a voltage V1 via the inductor 48 and a diode 62. When the voltage of an output terminal 24 drops below the predetermined level, a control device 100 operates a ground switch(GS) 109. When SG 102 is high, GS 109 is turned on and the inductor 116 accumulates an energy. When a voltage V2 reaches the predetermined level, the GS 109 is turned off and an energy accumulated in the inductor 116 is attenuated via the diode 22 and flows toward the output terminal 24.

Filed: 1995-01-27
Abstract: PURPOSE:To obtain a composition for oral cavity having an excellent suppression effect of pH reduction of a bacterial plaque, constituted by containing arginine, canavanine or their salts, and a carbon dioxide producing agent or carbon dioxide. CONSTITUTION:Arginine, canavanine which is an arginine analog, and their salts of 0.05-20wt.%, and a carbon dioxide producing agent or carbon dioxide of 0.5-20wt.% are contained in this composition. Further, a calcium ion capturing agent of 0.05-50wt.% is contained in it as indispensable component, and the other optional components which are added in an usual composition for oral cavity, are added to adjust pH of 5-10, when it is dissolved in water of 10 fold amount. By combining arginine, canavanie or their salts having a high safety and the carbon dioxide producing agent or carbon dioxide, with a manifestation of suppressing effect of lactic acid production, together with promoting effect of its decomposition, a reduction of pH of a bacterial plaque is suppressed. Since, even taking a food containing sucrose at the same time, the pH lowering is suppressed, a cariogenicity is reduced, and it is useful in fields of quasi-drug, a cosmetic and a food, and capable of changing a bacterial flora in the oral cavity to a flora rich with a goody bacteria.

Filed: 1980-02-02
Abstract: PURPOSE: To flow battery current between a welding rod and welding base metal intermittently at minute intervals and arc-weld the base metal by connecting a magnet coil to a manget iron core holding the welding rod.  
     CONSTITUTION: A welding base metal 5 and a DC magnet coil 1 are connected to a battery 6. Then, the output current of the battery 6 flows to the welding rod 4 and arc current flows between the rod 4 and the base metal 5. Then, the arc current flows to the magnet coil 1, and a magnet iron core 3 is attracted, by which the rod 4 is detached from the base metal 5. At this time, the arc current breaks, and the attraction force of the iron core 3 is lost. Therefore, the rod 4 is allowed to contact with the base metal 5 by a resilient spring 2. Again, the arc current is flowed by the battery voltage, and this is repeated, whereby the welding current is obtained.
