Abstract: A laser printer capable of controlling the operation of a fixing heater to heat a roller, including an energizing circuit for energizing a heater, a temperature detecting circuit such as thermistors, a noise canceling circuit, and a control circuit for controlling the energizing circuit and the heater. After receiving a voltage indicating an abnormal temperature of the heater over a prescribed length of time duration, the noise canceling circuit is configured to transmit a LOW level voltage to a latch circuit as an abnormality signal. The control circuit suspends the energization of the heater in response to the abnormality signal.

Abstract: An image forming apparatus has a light-emitting device, a photosensitive member being exposed to the light to form an electrostatic latent image on the photosensitive member, an image forming portion that forms an image corresponding to the electrostatic latent image on a recording medium, a cover, a light-emitting device control circuit, a first power supply that supplies electric power to the light-emitting device, a second power supply that supplies electric power to the light-emitting device control circuit, and a controller that includes a detection unit that detects the opening and closing of the cover and a power supply controller to control the electric power so that the first power supply stops to supply the electric power to the light-emitting device while the second power supply supplies the electric power to the light-emitting device control circuit when the detection unit detects the cover is open.

Abstract: A manganese dry battery with excellent leak-proof property is provided, in which electrolyte leakage does not occur even if the size of a positive electrode material mixture is increased to meet a demand for improvement in discharge property. In a sealing part, a first circular projection, a second circular projection and a third circular projection are arranged at the bottom in sequence from the center to the outside, and a positive electrode carbon rod supporting part is provided in an innermost periphery portion to have an interval from the first circular projection. A groove between the first projection and the carbon rod is formed to have a substantially rectangular vertical section, kraft board is pressed by flat bottom surfaces of the first and second projections and an opening of the zinc can is fitted between the second and third projections.

Abstract: The present invention provides a high-capacity cylindrical battery, wherein a burst-proof mechanism, which functions to discharge a gas outside when the internal pressure of the battery abnormally increases, does not sacrifice the space for power generating elements but increases the total capacity for power generating elements. The cylindrical battery of the present invention has a circular groove formed in the vicinity of an opening of a battery case, in which power generating elements are accommodated, the circular groove having a bottom that is bent inward the battery case and has at least one gas discharge aperture, which is sealed with a seal element. The seal element is an elastic ring to be set in the groove and seal the gas discharge aperture. This arrangement enables the gas discharge aperture to be sealed again even after the burst-proof mechanism functions, thereby ensuring a continuous use of the battery.

Abstract: Pest infestations of plant materials are controlled by the application of vaporized organic aldehydes of 3 or more carbon atoms, with at least the initial part of the exposure being performed under a subatmospheric pressure.

Abstract: Mosquito abatement is effected by administering to a water source containing mosquitoes an effective amount of a water-insoluble alcohol in a water-miscible form. The water-miscible form is provided in a wide variety of ways such as mechanical agitation (e.g. sonication), addition of a surfactant (e.g. a detergent), etc. The invention also provides labeled containers, including dispensers, containing a composition comprising a water-insoluble alcohol in a water miscible form and an affixed legible label providing instructions for the use of the composition for mosquito abatement.

Abstract: The present invention relates to Mucoriopsis ellipsoidus fungus. The invention also provides methods of extracting chitin from Mucoriopsis ellipsoidus and the chitin produced by this process.

Abstract: The present invention provides antimicrobial compositions, especially compositions comprising an antimicrobial (microbiocidal or microbiostatic) compound and a potentiator of antimicrobial activity. Compositions of the invention combining an antimicrobial compound and a potentiator are able to kill or inhibit the growth of microorganisms using much lower concentrations of the antimicrobial compound. The potentiator also enhances the efficacy of antimicrobial compounds against resistant strains of the microorganism.

Abstract: The sealing of the top and/or bottom of the cylindrical positive electrode of an air-cell is improved and leakage of the electrolyte from the jellied zinc negative electrode disposed within the positive electrode which is constituted of a collector layer, catalyst layer, and a porous layer is prevented. By utilizing a positive electrode constituted of a metallic collector layer made of a metal mesh or such, a catalyst layer disposed around said collector, and a fluororesin porous layer as an air diffusion layer, an outer cup and an inner cup are pressed on the top of the positive electrode in order to prevent the leakage of the electrolyte.

Abstract: The present invention relates to a process to manufacture alkaline cells by applying electrically conductive paint on an inner wall area of cathode container which contacts with cathode molds, and by heating said cathode container itself by applying electromagnetic induction in order to dry and/or cure the paint and to form a uniform electrically conductive coating layer adhered firmly on the inner wall of said container. By employing this process, continuous production of alkaline cells having excellent and uniform load characteristics which deteriorate very little became possible.

Abstract: The present invention provides a cylindrical alkaline battery comprising a positive electrode case of a cylindrical form having an opening at one end and accommodating an electricity-generating element comprising a positive electrode, a negative electrode, a separator and an alkaline electrolytic solution, an insulating gasket provided at the opening of the positive electrode case, a bottom plate being the negative electrode terminal provided on the gasket, and a heat-shrinkable member such as shrink tube or the like covering the outer surface of the positive electrode case. In this battery, the opening end of the positive electrode case and the outer surface of the battery extending therefrom are covered with an electrical insulating film.

Abstract: In a process wherein a slurry of water-containing coal and a solvent is heated to 100.degree.-350.degree. C. and then subjected to vapor-liquid separation by which water vapor is separated from the slurry to obtain a dehydrated slurry, a slurry to be dehydrated is mixed with a part of the dehydrated slurry and then heated. The dehydrated slurry thus obtained is suitable for use as a starting material for the hydrogenolysis of coal.

Abstract: Disclosed is a process for the treatment of water-containing coal which comprises mixing the water-containing coal with a hydrocarbon oil having a specific gravity higher than that of water at temperatures in the range of 100.degree. to 350.degree. C.; heating the resulting mixture at a temperature in the range of 100.degree. to 350.degree. C. and a pressure not lower than the saturated vapor pressure of water at that temperature; and then allowing the heated mixture to settle at a temperature in the range of 100.degree. to 350.degree. C. and a pressure not lower than the saturated vapor pressure of water at that temperature, whereby an upper layer consisting of the water separated from the water-containing coal is formed on a lower layer consisting of the mixture of the dehydrated coal and the hydrocarbon oil.
