Title: Dry-cleaning of garments using gas-jet agitation
Inventor: PURER EDNA M
IPC: D06F17/12
Filed: 1998-09-02
Granted: 2001-04-21
Abstract: Substantial amounts of particulate soils in garments (10) can be removed by agitation in gas-jet in a solvent-free, low-pressure environment. The ability of the present gas-jet agitation system (14) to remove particulate soils from garments and fabrics (10) rivals that of conventional dry-cleaning processes which agitate the garments and fabrics while immersed in solvent. Thus, a dry-cleaning operation may consist of a solvent-immersion step for removing soluble soils and a gas-jet agitation step to remove particulates. Considerable savings in equipment and operating costs may be realized in the practice of the invention, since solvent flow rates need not be boosted to provide necessary agitation for particulate soil removal. The savings achievable by employing gas-jet agitation are even more pronounced in dense phase gas dry cleaning systems, which require pressurized environments to maintain a liquefied solvent. Advantageously, the apparatus (14) employed in the practice of the invention has no moving parts and is relatively inexpensive to fabricate and maintain. Further, the gas (20) used as a means of agitation may be any commonly-available inexpensive gas, such as carbon dioxide, nitrogen, or air, so that the process is environmentally-friendly.

Abstract: A projection type liquid crystal display according to the present invention comprises a dichroic prism for separating or synchronizing a light to provide fundamental colors for color display, and unit for enlarging and projecting a transmitted light from the liquid panel. The liquid panel has one surface fixedly attached to a transparent member and the other surface integral with the dichroic prism directly or though at least one optical component. In the projection type liquid crystal display, the light which provides fundamental colors for color display and is separated or synchronized at the dichroic prism is incident on the light incidence surface of the liquid panel through the transparent member or the dichroic prism without contacting with the air in the space. The light incident on the liquid crystal panel is irradiated from the light outgoing surface of the liquid crystal panel through the transparent member or the dichroic prism without contacting with the air in the space and thereafter enlarged and projected. With this arrangement, it is possible to simplify the structure of the peripheral optical systems of the liquid crystal panel and to improve image quality.

Granted: 2001-04-21
Abstract: The present invention relates to a power factor correction (PFC) circuit. A winding set and a diode are connected in series between the bridge rectifier and the positive electrode of the electrolytic capacitor of the AC/DC rectifying circuit in the conventional switching power supply, and another winding set is connected in series between the positive electrode of the electrolytic capacitor and the DC/DC converter of the power supply. The two winding sets share the same magnetic core, so that the diode is switched between a backward and a forward bias state by controlling the polarity of the two winding sets. The AC power source is able to direct the input current into the electrolytic capacitor in each phase of the AC sine voltage without increasing the DC chain voltage on the electrolytic capacitor. The output terminal of the DC/DC converter is not influenced by the 120 Hz AC effect. Therefore, it is applicable to effectively improve the power factor of the input power of the switching power supply, and increasing the electrical performance and quality.
