Abstract: Provided are a non-volatile dual inline memory module (NVDIMM) supporting a DRAM cache mode and an operation method of the NVDIMM. The NVDIMM includes a DRAM chip, an NVM chip, and a controller that controls the DRAM chip to operate as a cache memory of the NVM chip. The controller sends a read command to the DRAM chip with reference to a cache address of data requested to be written from a host to the NVM chip, and sends a write command to the NVM chip with reference to an address of the data requested to be written at a time point when a read latency (RL) of the DRAM chip and a write latency (WL) of the NVM chip coincide with each other.

Abstract: A burner nozzle is disclosed, comprising a nozzle body that includes a slit such that a line passage to the slit opens in an outlet face surface at the surface of the burner nozzle body. A plurality of channels is connected to the slit. A group of first channels is connected to a source of oxidizing substance, and a group of second channels is connected to a fuel source. Each of the first channels and second channels have a circumferential passage to the slit at a non-zero distance from the outlet face surface. Furthermore, each of the first channels and second channels is formed to output a directed tubular flow towards a side wall of the slit, or towards a circumferential passage in a side wall of the slit. A safe pre-mixed burner configuration is achieved. A burner and a surface treatment device incorporating the burner nozzle are also disclosed.

Abstract: A gas burner system for food cooking appliances is provided. The system includes a gas supplying duct for delivery of gas to burner system. A first sump and a second sump are coupled to the duct through a pair of nozzles, such that the first and second sumps mix primary air with gas delivered by the duct. A pair of Venturi effect chambers are connected to the first sump and second sump respectively, and are inclined towards a pair of concentric burner components that include an outer burner component and an inner burner component. The Venturi effect chambers direct the air-gas mixture to the inner and outer burner components. Caps are provided over the first and second burner components.

Abstract: A device for intensifying a flame, comprising an object intended to be placed in front of the burner head, at a distance from said burner head, so that it is placed at least partly inside a flame extending from the burner head, and furthermore, said object being arranged to glow, heated by said flame. An apparatus for applying the device, for heating a liquid or air, comprising a burner and a combustion chamber, wherein the apparatus comprises an object in the combustion chamber. In the method, the device is installed in front of the burner head, or in an apparatus for heating a liquid or air, comprising an opening for the burner head, and a combustion chamber.

Abstract: A lantern which may be manipulated between a closed position in which it surrounds a mantle or mantles for the lantern to a second, opened position in which the globe has been moved or otherwise manipulated to provide access to the mantle or mantles. As an example, the globe may slide upward relative to the mantles so as to expose the mantles for changing. A globe for the lantern includes a frosted band located on a circumference radially outward from the mantle or mantles. The frosted band minimizes glare from the lantern, and the combination of the frosted band and clear sections located above and below the band provide illumination substantially equal to a clear globe.

Abstract: A gas operated lantern includes a control mechanism whereby a user may start gas flow through the lantern, operate a choke, and ignite the lantern. The user may perform these operations using the same control in an easy, simple series of motions. The user may rotate a knob, rotating a stem, to start gas flow and press the knob axially inward along the stem to operate a choke and an igniter.

Abstract: A toner for developing electrostatic images includes (a) toner particles having a weight-average particle size of 1-9 .mu.m, (b) hydrophobized inorganic fine powder having an average particle size of 10-90 nm and (c) hydrophobized silicon compound fine powder. The hydrophobized silicon compound fine powder has an average particle size of 30-120 nm, and a particle size distribution such that it contains 15-45% by number of particles having sizes of 5-30 nm, 30-70% by number of particles having sizes of 30-60 nm and 5-45% by number of particles having sizes of at least 60 nm. The hydrophobized silicon compound fine powder having a broad particle size distribution including coarse particles functions to prevent the embedding of the hydrophobized inorganic fine powder (functioning as a flowability improver) from being embedded at the toner particle surfaces, whereby the toner is allowed to exhibit stable performances even in a continuous image formation on a large number of sheets.

Abstract: A process for producing a sturdy refractory metal oxide article includes the steps of heating a substrate of organic material impregnated with a metal compound to thermally decompose the compound without substantial thermal decomposition of the substrate, further heating to decompose and remove the organic material and complete conversion of the compound to a metal oxide so that a metal oxide replica of the substrate remains and further heating to sinter and densify the replica such that the replica has a strength (shock resistance) figure of merit of at least three g-meters and the replica retains such strength after heating to 1500 C.

Abstract: The present invention relates to a pulsating gas fuel light source, utilizing a flexible diaphragm secured within a housing that reciprocates between two positions to generate a pulsating fuel flow thereby providing a lamp which flashes at regular intervals. The pulsating gas fuel light source is suitable for use as a highly visible warning light for construction sites on highways to warn passing traffic.

Abstract: A mechanically durable, highly luminous mantle for a gas-powered light source.

Abstract: Three cylinders containing a combustible gas under pressure are interchangeably attached to a lantern supporting stanchion to serve as a tripod stand for the lantern and provide a source of fuel for the lantern from one of the locations of attachment.

Abstract: In a device for the burning of gas by means of a mantle the improvement comprises a support for the mantle. The support includes attachment means for connecting it to a gas outlet tube emanating from the device. Lower body means is connected to the attachment means which is characterized as being substantially incapable of communicating significant amounts of gas from the interior to the exterior side wall of the lower body means. Connected thereto is an upper body means which is characterized as having a substantially porous side wall for the communication of gas to its exterior. A support plate having a substantially circular configuration is connected to the upper body means and, finally, mantle piercing means is caused to emanate from the support plate.

Abstract: An emergency mantle lamp is disclosed for use with a gas stove. The mantle lamp is adapted to be placed over a gas burner on a stove top. When the gas is turned on a perforated conical base conducts the flame upwardly to a formed mantle surrounded by a glass chimney. The mantle heated by the flame emits a fairly bright light for illuminating a room.

Abstract: An igniter device for a gas lamp of the type having a main mantle burner and a main control valve operated by a control lever, is provided with an auxiliary valve controlling the gas flow to an auxiliary burner the flame from which is directed onto the mantle to ignite this when fed with gas. The main control lever is connected to a piezo-electric spark generator which is operated by the lever to generate sparks as the main valve is moved to a fully open position. The auxiliary valve is also linked to the main control lever so as to be opened just as or just before the piezo-electric spark generator is operated whereby ignition of the auxiliary burner and hence the main burner is effected by the single operation of the main control lever to fully open the main flow control valve. The construction includes means for ensuring that the auxiliary valve is closed when the main control lever is released.
