Title: Biased-magnetization correction controller for converter output transformer
Inventor: OKUMA YASUHIRO
IPC: H02M7/537
Filed: 1993-02-17
Abstract: PURPOSE:To convert the voltage of a single-phase AC power supply into a positive- negative AC voltage pulse train in high frequency through a semiconductor AC switch on-off driven by a switching-signal generating circuit, and to reduce the number of the parts of a biased-magnetization correction control circuit for the output transformer of a converter circuit applied to a single-phase transformer. CONSTITUTION:An output from a transformer 15 detecting AC supply voltage is full- wave rectified by a single-phase full-wave rectification circuit 22, and the quantity of biased magnetization is obtained from the difference of a voltage time product during the period of application of a positive voltage pulse train to a transformer 13 and similarly a voltage time product for the period of application of a negative voltage pulse train regarding the full-wave rectified output voltage through a biased magnetization detector 21. A pulse-width command value 180 is corrected so that the quantity of biased magnetization is brought to zero and given to a switching-signal generating circuit 20a, and biased magnetization is corrected and controlled. Accordingly, the number of parts can be made smaller than a conventional circuit, in which the voltage of the transformer 13 is extracted by another transformer for insulation and biased magnetization is corrected.

Title: Heating element for thermal ink jetting
Inventor: SAKURAI KIKUICHI
IPC: B41J2/05
Filed: 1988-02-08
Abstract: PURPOSE:To converge heat fluxes from heating elements in one direction to realize the heating element with a favorable thermal efficiency, by a method wherein, the surface other than the upper surface of the heating element is covered with a thermally insulating material, and on the upper surface of the heating element a thermally conductive body is formed. CONSTITUTION:As a substrate 102, a ceramic, a glass, or the like is used. A thermally insulating material layer 104 formed on the substrate 102 uses a heat resistant organic resin, a porous material, an amolphous material, or the like having a specific heat which is sufficiently smaller than that of a heating element 106 or an electrode 108 and a small thermal conductivity. The heating elements 106 formed on the thermal insulating material layer 104 is provided by vapor deposition or sputtering. A protective layer 110 protecting the surface except the upper surface of the heating elements 106 uses the same material as the thermal insulating material layer 104. In this manner, the most of heat fluxes generated by the heating elements 106 can be transmitted to an ink through a conductive body 112. On the other hand, the thermally insulating material formed on the surface other than that of the heating elements can reduce the lateral diffusion, especially, to the electrode couples of the heat flux flowing into the thermally conductive body.
