Title: Electrophotography device
Inventor: NARITA MITSURU
IPC: G03G21/08
Filed: 1989-01-13
Abstract: PURPOSE:To restrain the surface potential of a photosensitive body from lowering and to obtain an excellent image without fogging as to printing quality by specifying the wavelength of destaticizing light. CONSTITUTION:Since electric field is hardly impressed on an exposing part in the case of destaticization, carrier is generated in a charge generation layer and the carrier, especially negative charge, is easy to be left in a boundary between a surface protective layer and the charge generation layer or in the charge generation layer when the light of long wavelength is made to irradiate. Therefore, in an electrostatic charging process which is a next process, the remaining carrier and positive charging negate each other and the surface potential of the photosensitive body lowers. By setting the wavelength of the destaticizing light at <=680nm on the basis of such mechanism, the negative space charge is made as little as possible. Thus, the electrostatic charging potential is suppressed from lowering and excellent printing without fogging is accomplished.

Title: Method and device for gasifying waste
Inventor: KONISHI SUGIHIRO
IPC: B09B3/00
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To gasify water-containing waste in a short time without auxiliary combustion, by putting the waste under a high pressure and high temperature condition for a few minutes to turn it into slurry and to change it to low molecular organic substances by hydrothermal decomposition, and by dehydrating the waste at the same time. SOLUTION: For instance, waste 5 such as sewage sludge is concentrated to a required water content, and subsequently introduced into a reaction evaporation device 8 to be separated into steam 20 and organic substances 5b converted to low molecular weight substances to be liquefied, by hydrothermal decomposition in a reaction evaporator 8c, and the organic substances 5b are turned into slurry and introduced into a gasified furnace 11. Next, the organic substances 5b are partially oxidized with oxygen 9 in the gasified furnace 11 to generate crude gas 10 such as carbon monoxide and hydrogen are generated, and the crude gas is purified in a scrubber 13 by the treatment such as dedusting and desulfurization to form purified gas 12.  Thus, the waste 5 such as sewage sludge is not only treated but also gasified solely without auxiliary combustion, so that the gasified purified gas 12 is burnt to be effectively used for power generation.

Title: Linear motor and x-y table machining apparatus
Inventor: HIROTA MINORU
IPC: H02K33/18
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To prevent the excessive temperature rise of the coil passing part of a yoke which generates heat when the coil is energized by supplying compressed air to the part for cooling the part. SOLUTION: An air duct 6 is installed around an upper yoke 2 so that the air outlets 6a of the duct 6 can be directed to the surface of the yoke 2. An annular magnetic flux loop is formed of permanent magnets 3 and yokes 2, 5, and 5 so that a coil 1 can linearly move forward and backward in accordance with the Fleming's left-hand rule when the coil 1 is energized with a prescribed current. Since compressed air for cooling is discharged toward the whole peripheral surface of the yoke 2 nearly over the full length of the yoke 2 from the outlets 6a of the duct 6, the temperature rise of the yoke 2 which generates heat due to eddy currents when the coil 1 is energized can be suppressed considerably by the cooling effect of the compressed air and the thermal deformation of the yoke 2 can be prevented.

Title: Heat exchanger
Inventor: SUGANO TADAO
IPC: F24H9/00
Filed: 1983-01-19
Abstract: PURPOSE:To reduce generation of CO due to flame cooling by contriving shortening of a flame length by making a combustion speed of the flame high, by providing a plurality of units of inner fins in an axial direction of the inside of a heat exchanger and a primary air-fuel premixing burner on one end of the heat exchanger. CONSTITUTION:A combustion is kept on by forming a combustion flame 2 by a burner 1. Combustion gas 2' of a high temperature generated within a heat exchanger 3 is entered into a combustion cylinder 6 from an opening part 6' and comes back to the opening part 6' by converting its advancing direction on the way. The combustion gas 2' of high temperature is converted its direction further and is passed through a gap between the external circumference of a combustion cylinder 6 and an inner fin 4. Then heat exchange is done between the combustion gas 2' and the inner fin 4. The heat exchange is expedited further by a baffle plate 7. Then, heat is transferred from the inner fin 4 to an outer fin 5. In addition to the above, when a convection fan 9 starts, an air flow occurs and touches the surfaces of the heat exchanger 3 and the outer fin 5 forcibly and heat exchange is performed between air and the combustion gas 2' in the heat exchanger 3.

Title: Control element driving device
Inventor: ITO MASAHIKO
IPC: G21C7/14
Filed: 1989-01-18
Abstract: PURPOSE:To enable automatic scramming in case of an abnormal temperature rise of a cooling material and facilitate the replacement of an electromagnet by providing a permanent magnet opposite an armature at the upper end of a control element. CONSTITUTION:If the temperature of the cooling material rises abnormally for some reason during the operation of a nuclear reactor, the armature 36 and permanent magnet 102 rise in temperature and when at least either one nearly reach the Curie point, the attractive force between the both is lost, so that the armature 36 separates from a permanent magnet type attraction device 10. The control element, therefore, falls by gravity and is inserted into a reactor core to attain the nuclear reactor scramming. Even when the temperature is lower than the Curie point, artificial nuclear reactor scramming is performed by pressing a push rod 107 down by an up/down driving device. Consequently, the automatic scramming in case of the abnormal temperature rise of the cooling material and the replacement of the electromagnet are easily enabled.
