IPC: G03G9/08
Filed: 1985-02-16
Abstract: PURPOSE:To ensure high fluidizability and stable electrification development characteristics of a toner by mixing fine particles as a fluidizing agent electrifiable to a polarity same as that of the surface charge of an image bear ing body with the toner. CONSTITUTION:The fine particles as a fluidizing agent electrifiable to apolarity same as that of the surface charge of an image bearing body are mixed with the toner in an amt. of 0.1-2 wt. % of the toner, and they are made of an oxide of a metal, such as Al, and have an average particle diameter of 5-100 mum. When added too small, a fluidizing effect is deteriorated, and when added too much, action for grinding and removing matters attached to the surface of the image bearing body is not exhibitted, thus permitting the surface of the image bearing body to be cleaned well, not to need to be coated with a metal soap film, and sharp images high in density to be always obtained.

Title: Method of distillation at room temperature
Inventor: TAKADA KAZUHARU
IPC: C02F1/04
Filed: 1979-03-13
Abstract: PURPOSE: To economically change seawater into fresh water, by maintaining a plant under a high-degree vacuum and distilling the seawater at room temperature.  
     CONSTITUTION: Seawater of about 30°C is passed through a filter 15. The seawater is then sucked into an evaporation chamber 1 through a brine pipe 13 without being preheated. The evaporation chamber is maintained under a vacuum. The seawater is widely sprinkled over a horizontal heat transfer tube 3 from a seawater sprinkler 2. Steam, which is compressed by a compressor 10 and whose temperature is raised to about 35.5°C by supplying energy to the steam, is introduced into the heat transfer tube 3. Heat exchange is caused between the steam and the sprinkled seawater and heat balance is maintained between them. Evaporation is takes place on the outside surface of the tube 3 so that steam of about 33.5°C is generated. The former steam in the tube 3 is condensed. The condensed water flows out of the tube 3 and stays in a distilled water chamber 5. Incondensible gas such as air joins the condensed water introduced from the chamber 5 through a pipe 22. The mixture is sucked into a vacuum pump 19. The incondensible gas is released into the atmosphere through a gas separator 24. The condensed water is picked out of a pipe 26.

IPC: F02D41/16
Filed: 1986-02-12
Abstract: PURPOSE:To provide simple constitution by generating a rotational speed regulating signal as opening signal in place of a throttle opening detecting signal in the output of a full closing signal of a throttle valve to set the rotational speed corresponding to the opening signal as a desired idling rotational speed. CONSTITUTION:When a full closing detecting means M3 generates the full closing signal of a throttle valve, a change-over means M4 generates the regulating signal output of a rotational speed regulating means M2 as an opening signal in place of the detecting signal output of a throttle opening detecting means M1. And the rotational speed corresponding to the opening signal generated in the output of said full closing signal is set as a desired idling rotational speed by a rotational speed setting set as a desired idling rotational speed by a rotational speed setting means M5. Namely, the desired idling rotational speed is set according to the opening signal from the change-over means M4 in the output of said full closing signal. Thus, the desired idling rotational speed is altered by a simple constitution without providing exclusively an input circuit in an electric controller.
