Abstract: PURPOSE:To obtain a clear TV picture image on a fluorescent screen by a main focussing lens through a combination of unipotential and bipotential type electron lens and specifying their mutual interval. CONSTITUTION:The electrode of a composite type electron lens consists of an arrangement of the conical first to fourth electrodes 1-4. When the potential for the electrodes are V1-V4, respectively, the first potential condition and the second one are set to V2<V1 or V3<V4 and V1 or V3<V2<=V4, respectively. The dimensional condition which determines the characteristics of such an electron lens system is the distance l between the unipotential type electron lens consisting of the first to third electrodes and the potential type lens consisting of the third and fourth electrodes. This distance l is set to 0.6D-1.5D. This can produce a clear TV picture image on a fluorescent screen by small diameter beam spots.

IPC: C21D8/12
Filed: 1981-05-19
Abstract: PURPOSE:To obtain an electromagnetic steel sheet having a magnetic property and an insulating property under a stable condition, while raising an iron loss- improving effect, by forming a tension film on one surface of the electromagnetic steel sheet, irradiating laser beams to the other surface, and then coating the other surface with an insulating film at a proper temperature.

Filed: 1981-05-18
Abstract: PURPOSE:To increase the lifetime of a dry battery by supplying a driving current of a switching circuit and a driving current of the second constant-voltage circuit for stabilizing the output voltage through resistors from the first constant-voltage circuit. CONSTITUTION:When an input voltage VIN is lowered and the input current of the amount corresponding to the lowered voltage tends to increase, the driving current of two driving currents branched from the output terminal of a resistor T22 and the zener current of a constant-voltage diode D13 will increase since the current which flows through the resistor R22 as a current source of the driving current of a transistor Q11 is constant. Accoringly, the zener current is decreased, the operating point of the diode D13 is displaced from the constant-voltage operating range, and the outut voltage VOUT will gradually increase. Since the zener current of the diode D13 is thus gradually decreased, the output voltage VOUT is not stabilized, and is further lowered upon decrease of the input voltage VIN.
