Title: Conversion of heat energy to mechanical energy and heat engine
Inventor: TANAKA TSUYOSHI
IPC: H02N11/00
Filed: 1989-06-14
Abstract: PURPOSE:To move a pair of magnets and to convert heat energy into mechanical energy stably with high thermal efficiency by arranging a magnetic substance between these pair of magnets, shielding magnetism and then heating and cooling the magnetic substance to change the permeability. CONSTITUTION:A magnetic substance 3 is arranged between a magnet 1 and a magnet 2. If the magnetic substance 3 is heated to a Curie temperature and over, the magnetic permeability and magnetic susceptibility will be 0; the magnetic shielding will be reduced and magnetic repulsive force generated between magnets 1 and 2. If the magnetic substance 3 is cooled to the Curie temperature and below, the magnet 1 will magnetically be shielded from the magnet 2 with the magnetic substance 3 and magnetic attractive force will be generated between the magnetic substance 3 and magnet 2. If the magnet 2 is fixed, the magnet 1 will be able to perform reciprocating movement. The heat energy can thereby be converted into the mechanical energy.

Filed: 1984-07-23
Abstract: PURPOSE:To enable a liquid electrolyte to be supplied into the matrices by packing an electrolyte-holding material into one end of each of the fuel and the air electrodes and forming an electrolyte supply path in each of the separators. CONSTITUTION:Each unit cell is formed by placing a matrix 3 between a fuel electrodes 2a and an air electrode 2b positioned in such a manner as to locate their gas flow paths 2aS and 2bS perpendicular to each other. When a fuel cell is constituted by stacking thus formed unit cells with separators 4 interposed, a cut is formed in one end of each of the fuel and the air electrodes 2a and 2b and a pasty electrolyte-holding material 6 prepared by mixing a silicon carbide powder into a liquid electrolyte is packed into the cuts. Additionally, joint pipes 7 continuous with an electrolyte container 8 are connected to the separators 4. Because of the above structure, it is possible to easily and securely supply the liquid electrolyte into the matrices 3 from their outside without any necessity of complicated formation of the electrodes 2a and 2b even when they are thin.

Title: X-ray fluorescence analyzer
Inventor: NAKATANI TAKEHIKO
IPC: G01N23/223
Filed: 1991-06-24
Abstract: PURPOSE:To prevent the emission of fluorescence X rays affecting the analysis of a sample and to enhance the accuracy of the analysis by providing a sample mask which is covered with the intermediate layer comprising heavy metal and the uppermost layer comprising the same material as the target material of an exciting X-ray source. CONSTITUTION:When exciting X rays are cast on the vicinity of an analyzing window 16, fluorescence X rays are emitted from the layers of a substrate 11 and multiple layers 14 in addition to a sample 10. Of these X rays, the fluorescence X rays (when the substrate 11 is made of stainless steel, the fluorescence X rays of Fe, Cr, Ni and the like are main parts) are absorbed with an Au layer 12 of the multiple layers 14. The fluorescence X rays from the Au layer 12 are absorbed with an Rh layer 13 at the upper layer. The fluorescence X rays from the Rh layer, which is the uppermost layer, enter into an X-ray analyzing part together with the fluorescence X rays from the sample 10. Since an X-ray tube for an Rh target is used, the emission of the fluorescence X rays from the uppermost Rh layer 13 does not become problem. When the X-ray tube for a chromium target, a molybdenum target or the like is used, the same metal as the target is used for the uppermost layer.

Title: Transfer device for color electrophotographic copying machine
Inventor: KATSUTA ISAO
IPC: G03G15/01
Filed: 1984-07-23
Abstract: PURPOSE:To increase transfer speed and to improve copying efficiency by the constitution in which color transfer is executed by using a transfer drum and that monochromatic copying or black and white copying is executed in the same manner as for an ordinary black and white copying machine without using the transfer device. CONSTITUTION:In monochromatic copying or black and white copying, the transfer drum 1 moves toward an arrow A and is put in a stationary state; at the same time, a corona discharger 2b and an auxiliary paper transport 7 are moved toward an arrow B to the position in proximity to the surface of a photosensitive drum 4, by which said copying is executed. The main paper transport 3 changes the introducing part thereof toward an arrow C so as to move near to the ejection side of the transport 7. The transfer paper 15 delivered by a timing roller 11 is thereby copied by the copying process similar to the copying process of the black and white copying machine. The copying speed is thus increased and the copying efficiency is improved.

Title: Control circuit of machinery
Inventor: NAKAMURA MASAKI
IPC: H05B3/00
Filed: 1980-10-29
Abstract: PURPOSE:To cause a change of time limit more than an inverse proportion, by comparing the voltage obtained by subtracting the fluctuation of the power supply voltage from the constant voltage output of a constant voltage circuit with the charging voltage of a charging capacitor in a CR integral network and then controlling the conduction time of a load. CONSTITUTION:When a power supply switch 2 is closed, a heater 20 conducts to charge a capacitor 6. When the charging voltage of the capacitor 6 reaches the gate voltage of a PUT12, the PUT12 is turned on. Then a pulse output is delivered to a cathode terminal 13. Accordingly a thyristor 19 is turned on to flow the current to a solenoid 18. Thus the switch 2 is opened to cut off the current to the heater 20. In case the power supply voltage has a fluctuation, the voltage proportional to the power supply voltage is subtracted from a certain level of voltage decided by a constant voltage diode 9. As a result, the changing factor of the gate voltage of the PUT12 becomes larger than the fluctuation factor of the power supply voltage.
