A liquid fuel burner for burning liquid fuel in the form of a gaseous mixture with air. The liquid fuel burner has a porous member provided at least with a fuel receiving section for receiving the liquid fuel supplied to the burner and a fuel evaporation section from which the liquid fuel is evaporated. An air supplying device is provided for forcibly supplying air to the fuel evaporation section. The rate of air supply is varied by means of a damper or like means. Heating means are provided for maintaining the fuel evaporation section at a substantially constant temperature. The rate of burning is varied while maintaining the air-fuel ratio of the mixture substantially constant, because the rate of evaporation of the fuel is almost in proportion to the rate of supply of air to the fuel evaporation section. The heating means facilitates the evaporation of the fuel and permits a rapid rise and stabilization of burning after ignition.

Liquid gas burner

The present invention is directed to a method and an apparatus for formation of images by particles on a photosensitive plate. Particles employed are translucent, whereby a charge holding the particles to the photosensitive plate may be efficiently removed from selected particles by image-wise light from an original document, etc., so ensuring production of well-defined images. For production of color images, there is employed a panchromatized plate and particles which are transparent to different types of light and have associated therewith dye material permitting production of clearly defined color images, it being made possible to obtain a color copy of an original document in a process requiring only one exposure stage and only one development stage.

Image formation method having translucent particles containing a

Disclosed is a light transmission particle containing a colorless sublimable dye, an acyl leucophenoxazine compound suitable for use in the formation of a color image. This particle can produce a clear color image having little fogging and having an excellent resolving power.

Light transmission particle for forming color image

Disclosed is a light transmission particle containing a colorless sublimable dye that is a spirobenzopyrane indole compound suitable for use in the formation of a color image. This particle can produce a clear color image having little fogging and having an excellent resolving power.

Image forming particles for use in electrostatic image formation, which particles have a light transmitting property, said particles comprising an electrically conductive material and subliming substance. The electrically conductive particles exhibit superior translucency which enables a charge preliminarily imparted to a photoconductive support member to be readily erased upon exposure to light image from an original, with consequent reduction of electrostatic attraction between the particles and the support member to minimum for presenting clear and definite images without fogging. Furthermore, the particles are electrically independent due to absence of electrostatic attraction therebetween and because of their electrical conductivity adhere to the support member by electrostatic induction of the charge imparted to the latter without adhesion between the particles, thus being uniformly arranged on the support member in one single layer and as close to each other as possible, thus offering resultant images of superior quality.

Electrostatic image forming process and particles comprising reactive

The present invention relates to an electrophotographic color process comprising the steps of: (a) charging an electrophotographic light-sensitive material by corona discharge, said material having at least two kinds of color-producing photoconductive particles disposed at random on an electroconductive support, said color-producing photoconductive particles consisting essentially of a photoconductive particle, a sensitizer and a leuco dye, (b) exposing said charged material to light, (c) developing said material by toner containing acid substance, and producing color in the leuco dye by the interaction of the leuco dye with the acid substance, and forming a color image by carrying out once the procedure of charging, exposing and developing. An electrophotographic light-sensitive material comprising an electroconductive support and a photoconductive layer consisting of at least two kinds of color-producing photoconductive particles disposed at random on the support, said color-producing photoconductive particles consisting essentially of a photoconductive particle, a sensitizer and a leuco dye.
