Publication number: 20070220683Abstract: A nonvolatile semiconductor memory device which is superior in writing and charge holding properties, including a semiconductor substrate in which a channel formation region is formed between a pair of impurity regions formed with an interval, and a first insulating layer, a floating gate, a second insulating layer, and a control gate over an upper layer portion of the semiconductor substrate. It is preferable that a band gap of a semiconductor material forming the floating gate be smaller than that of the semiconductor substrate. For example, it is preferable that the band gap of the semiconductor material forming the floating gate be smaller than that of the channel formation region in the semiconductor substrate by 0.1 eV or more. This is because, by decreasing the bottom energy level of a conduction band of the floating gate electrode to be lower than that of the channel formation region in the semiconductor substrate, carrier injecting and charge holding properties are improved.Type: ApplicationFiled: March 20, 2007Publication date: September 27, 2007Applicant: Daewoo Electronics CorporationInventor: Chang Hoo Kim

Patent number: 7254967Abstract: A drum-type washing machine is equipped with a drying device, which increases condensing efficiency by increasing the contact of air flowing along a condensing duct with cooling water, and prevents water formed in a condensing duct from flowing into a fixed drum. The washing machine is equipped with a drying device, which includes a discharging duct to connect an outlet of a blowing fan with an air inlet of a fixed drum and provided with a heater therein, and a condensing duct to connect an air inlet of the fixed drum with an inlet of the blowing fan and provided with a condensing unit to remove moisture. The condensing unit includes a cooling water dispersion member disposed in the lower portion of the inside of the condensing duct and a cooling water supply pipe configured to supply cooling water to the cooling water dispersion member.Type: GrantFiled: March 27, 2003Date of Patent: August 14, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Jae-Myong Kim, Kwang-Su Kim

Patent number: 7249472Abstract: The invention relates to a device for treating web-type textiles, nonwovens or paper in a continuous stream, uses a gaseous treatment agent that circulates in the device. The product lies on the exterior face of a permeable drum (5), which is subjected to an induced draught and has two base sections (11, 12) on its front face, more precisely on a sieve-type or perforated surface (9), which covers the drum structure. A perforated drum jacket (15), whose edges are merely clipped into the two base sections (11, 12) extends between said base sections (11, 12). To achieve this, an annular groove (17) is machined into the base sections (11, 12). The edge of the sheet metal (15) and a ring-shaped clip segment (23) are inserted into said groove and are retained there by means of screws.Type: GrantFiled: July 12, 2001Date of Patent: July 31, 2007Assignee: Fleissner GmbH & Co.

Patent number: 7213349Abstract: While venting clothes dryer heat outside may be acceptable during the summer months, it is desirable to reuse such heat once the outside temperature starts to fall. The disclosed heat recovery unit for a clothes dryer works towards meeting this need. The heat recovery unit may include a housing having a support box and a cover attached to the support box by a hinge. The cover may include an exhaust register and an indicator light cover through which a ‘clean filter now’ light, a ‘low flow’ light, and a ‘high temperature warning’ light may be viewed when lit. The heat recovery unit also may include a controls box positioned in the support box, where the controls box maintains electronic intelligence of the recovery unit. A recovery unit fan may be positioned in the support box to blow room temperature air up through a heat exchanger in the support box. An internal bypass channel may channel clothes dryer air around and outside of the heat exchanger during hot days.Type: GrantFiled: August 1, 2006Date of Patent: May 8, 2007Inventor: Richard A. Brunner

Patent number: 7168274Abstract: The combination washer/dryer and method for operating a combination washer/dryer. The washer/dryer has a containment drum which receives wash water, and includes a perforated clothes drum which rotates within the containment drum. A heat plenum is provided in heat transfer relationship with the containment drum, and a source of heat coupled to the heat plenum supplies heat for water in the containment drum. During a drying cycle, hot air from the heat source supplied from the fire box to the containment drum for heating wash water during a washing cycle, and for supplying hot air during a drying cycle. A drying air plenum is connected to receive drying air from the source of heat, delivering the drying air to the top of the containment drum, where it enters the rotating basket. An exhaust plenum discharges hot air laden with moisture from the containment drum through a lint filter.Type: GrantFiled: May 5, 2003Date of Patent: January 30, 2007Assignee: American Dryer CorporationInventors: Dennis Slutsky, Craig F.
