Decoration lamp

The present invention generally relates with filling air string unit in decorative lighting string. This filling air string which to make the lighting string to expandable or to shrinkable with lighting device and the firm device. This filling air string is made up from soften plastics which has a filling air room. The lighting string will made up into many different kind of shapes when volume expansion when expand and sufficient the air. The lighting string will minimize the volume when emit the air. This filling air volume has a gas room in the central that has some capacity for this lighting device. As this lighting device firm in the central of this gas room to be able to reveal any kind of shapes and clearly to showing the lighting string while rising this filling air string.

Decorative lighting string with filling air type

An apparatus and a method for detecting ignited flammable gas in a conduit or for detecting the impurity content of a gas composition are described. In the apparatus, a sensor body is provided which is equipped with at least one perforated isolator plate for slowing down the flow of an ignited flammable gas when fed back into the cavity of the detection apparatus. The sensor body further includes at least one optical sensor mounted juxtaposed to a gas inlet for sensing an ignited flammable gas and for sending a signal to a controller for shutting off the flammable gas supply. The present invention novel apparatus can further be utilized to detect the impurity level in a gas composition, and to detect any reaction product between a flammable gas and a material that forms the chamber component.

Apparatus and method for detecting ignited flammable gas in a conduit

An apparatus and a method for stopping the propagation of an ignited flammable gas in a conduit used in semiconductor processing are proposed and described. In the apparatus, a mounting mechanism and a bullet are provided inside an elongated conduit body wherein the bullet is detachably mounted to the mounting means, while the mounting mechanism is fixedly attached to an inside wall of the elongated conduit body. The bullet is equipped with an explosive pack in a body portion and a bullet head in a head portion. When a flame from an ignited flammable gas enters the conduit and ignites the explosive pack, the bullet is propelled into and frictionally engaging the inlet end of the conduit body such that an internal passageway in the inlet end is substantially blocked to prevent the further propagation of flame upstream into the conduit. The bullet utilized in the present invention novel apparatus may be suitably supplied with a tapered body such that the tapered surface advantageously engages the internal passageway in the inlet end of the conduit body when the bullet is by the explosion of an explosive pack toward the inlet end.
