Title: Conductive image forming particles
Inventor: TAKASHIMA YUUJI
IPC: G03G15/22
Filed: 1977-11-16
Abstract: PURPOSE: To enhance resolution in electrophotography, by attaching transparent films containing copper iodide on the surfaces of fine particles to form conductive image forming particles, thereby enhancing fluidity of the particles, and by reducing electric resistivity.  
     CONSTITUTION: Paricles 1 of about 5W80 μ in diameter prepared by dispersing pigment,dye, or the like in a transparent resin, such as polystyrene or acrylic resin are coated with layer 2 prepared by dispersing copper iodide in a transparent hydrophobic resin, such as arcylic, vinyl acelate, or the like resin. Such coating permits particle resistivity to be lowered below about 10 6  ohm cm, agglomeration of particles 1 due to triboelectricity to be prevented, and the releasability of particles 1 freed of static attraction by imagewise exposure from a photoreceptor to be also enhanced; therefore, superior electrophotographic images to be obtained.

Title: Heat exchanger
Inventor: SAHO NORIHIDE
IPC: F28D9/00
Filed: 1990-05-30
Abstract: PURPOSE:To achieve a higher heat exchange efficiency through uniform of temperature distribution of fluid within a passage by packing a laminate layer of a fine metal material comprising a highly heat conducting material and a fine metal material comprising a low heat conducting material to integrate mutual contact metallurgically between a heat transfer plate wall, a passage wall, a fin and the fine metal materials. CONSTITUTION:A high temperature and high pressure fluid A flows in at an inflow port 11 and a low temperature and low pressure fluid B flows in at an inflow port 23. The fluids undergo a heat exchange flowing respectively through a passage 1 and a passage 13. The main heat moving route is as follows: the fluid A-metal particles 8-a heat transfer plate 14-metal particles 19-the fluid B. A fin 7, a fin 8 and a plate 2, a plate 14, a side wall 3, a side wall 15, an upper wall 5, an upper wall 16, a lower wall 6, a lower wall 17, metal particles 9 and metal particles 20 are made of stainless steel with a small heat conductivity and hence, heat transfer of this route is very limited. The stainless metal particles 9 and 20 serve to prevent heat from flowing into a low temperature part with a temperature difference between upper and lover ends of the heat exchangers. The heat conductivity of the heat transfer plate 4 is larger than stainless steel and smaller than copper. Heat transfer surface areas of the metal particles 8 and 19 and fin efficiency of the metal particles have great effect on heat exchange efficiency.

Title: Coke oven cover
Inventor: MOJI TOSHIHIKO
IPC: C10B25/02
Filed: 1987-06-02
Abstract: PURPOSE:To attain maintenance of an intra-stopper passage pressure so as to be advantageous against leakage of produced gas and admission of air, by operating a pressure control plate disposed in a passage for gas ascension formed at the stopper part of an oven cover projecting in a coke oven chamber. CONSTITUTION:Part of a coke oven gas produced from a coal 2 fed into a carbonization chamber enters a stopper region opening 28 for introduction of produced gas, goes through a stopper region passage space, reaches an oven top space 5, and gets out of the oven through a riser pipe hole 7 along with a gas which has traveled through charged coal pieces. The pressure detected by a pressure detector 35 installed in a stopper region passage space is converted into an electric signal by a converter 36, and conveyed by a conductor 37 to a manipulator 38 by which a pressure control plate 30 disposed in the stopper region passage is operated. In the initial stage of coal charging when the amt. of produced gas is large, since the detected pressure is positive the operation by the manipulator 38 is performed so as to cause the cross section of the stopper region passage to be at a maximum. In the latter stage of carbonization when the amt. of produced gas is small, the pressure control plate 30 is manipulated so as to decrease the cross section of the stopper region passage in accordance with the detected pressure, thereby preventing admission of air into the carbonization chamber due to the pressure of the chamber becoming negative.
