Title: Electronic engine control device
Inventor: ABE KUNIHIRO
IPC: F02D45/00
Filed: 1985-12-03
Abstract: PURPOSE:To enhance the starting ability of an automobile engine to aim at simplifying a radiation system with the use of an electronic engine control device for the engine, by providing a voltage boost stopping function to a pressure booster circuit disposed between a constant voltage circuit and a battery. CONSTITUTION:An electronic engine control device comprises a voltage booster circuit 4 between a constant voltage circuit 2 for feeding a predetermined operat ing voltage to a control circuit 3 and a battery 1. When a starter switch 5 is turned on, a starter motor 7 is driven to crank an engine which therefore is started. At this time a relay 6 is energized to change over contacts 6a, 6b into the voltage booster circuit 2 side, and therefore, the voltage booster circuit 2 increase a battery voltage up to a value substantially twice as large as the original value, and feeds the boosted voltage to the constant voltage circuit 4. Thus, erroneous operation of the control circuit 3 is prevented, thereby it is possible to enhance the starting ability of the engine.

Title: Lead-acid battery
Inventor: TERADA MASAYUKI
IPC: H01M4/68
Filed: 1988-10-28
Abstract: PURPOSE:To enhance the charging performance of a battery which is allowed to stand after overdsicahrge by forming a PbF2.SnO composite oxide on the surface of a positive current collector. CONSTITUTION:A PbF2.SnO composite oxide is formed on the surface of a positive current collector. Since the PbF2.SnO composite oxide has high electric conductivity, good sulfuric acid resistance and oxidation resistance, electric conductivity between the current collector and an active material is kept good. Since the composite oxide layer prevents the corrosion of the current collector, the surface of the current collector is hardly converted into a lead sulfate layer. Even if the lead sulfate layer is formed on the current collector, since the PbF2.SnO composite oxide exists in the lead sulfate layer, charging current can flow through the composite oxide.

Abstract: PURPOSE:To have a high quality image with uniform spot shape by forming cross-over in the cross-section of a beam when a vertical deflection electrode is traversed, and thereby lessening the deflection distortion resulting from frame abberation. CONSTITUTION:A voltage V1 is impressed on a back face electrode 1 while another voltage V2 higher that V1 is impressed on a drawout electrode 3, and then a voltage V0 as V1<V0V2 is impressed in the condition that a heater current is flowed to facilitate electron emission through heating of a wire electrode 2, and now the surface electric field of the wire electrode 2 becomes positive to cause emission of an electron stream, which is accelerated toward the drawout electrode 3. If V0 as V0>V2 is impressed, the surface electric field of the wire electrode 2 becomes negative, and electron mission is suppressed. Now emission of the electron beam is repeated at certain intervals from the upper electrode 2 one after another by controlling the voltages individually, and a sheet-shaped electron beam is generated which has a current distribution uniform in the horizontal direction for each wire electrode 2. Further, a voltage V3 is controlled secularly for accomplishment of correspondence to image signal, to control the amount of beam passage individually beam by beam, and thus the beam reaches a convergence electrode 5.
