Abstract: A high frequency and high voltage generating circuit for a discharge lamp lighting device controls its initial output at the starting time of a discharge lamp to prevent applying a high voltage to the discharge lamp in the "cold cathode" state. The circuit comprises in combination an oscillation circuit having an oscillation capacitor, a non-linear inductor and a thyristor, and an initial output limiter for delaying the output supply until the lamp filament is sufficiently preheated for preventing sputtering and for extending the operational life of the discharge lamp. The output control is formed as a bias circuit for the nonlinear inductor and includes a thermistor with a negative or a positive temperature coefficient.

Abstract: It is the purpose of the present discharge lamp lighting system to provide reignition energy to a discharge lamp in each half cycle of the a.c. power source. The discharge lamp is connected to a conventional a.c. power source through ballast means and an oscillation booster circuit, which provides an intermittent oscillation output for the reignition operation of the discharge lamp. The operation period of the intermittent oscillation output is so controlled that the reignition operation period is included in each half cycle of the discharge lamp current. The lamp voltage and source voltage are established to agree as much as possible with each other for minimizing the terminal voltage of the ballast means, whereby a compact and economical device with a small inductance ballast means is achieved.

Abstract: A brushless polyphase DC motor is applied to a spindle motor for a disk device and has a stator generating a magnetic field in an excited state and a rotor obtaining turning force by the electromagnetic interaction with the stator. When an electrical charge current is intermittently and alternately supplied to the coil of the stator in opposite directions, for example, if electrical charge is stopped after current in the normal direction is supplied, a residual magnetic field density is generated in the stator during the stopping period. The residual magnetic flux density is employed for performing electrical charge in the reverse direction by supplying current in the reverse direction. In this case, a high torque is generated by increasing a change in the magnetic flux density.

Abstract: A high intensity discharge (HID) lamp has an arc tube including a pair of main electrodes and at least one auxiliary electrode or probe, wherein a high frequency (HF) high voltage is applied to the probe for forming a high frequency (HF) ignition discharge for establishing a low frequency (LF) arc discharge between the main electrodes. In this ignition system, the electrodes of the arc tube are arranged so that an LF discharge path and an HF discharge path are positioned in an X- or a Y-configuration in the arc tube for causing easy lamp ignition. Also, to simplify the outer leads, it is desirable to mount the probe on one of the main electrodes by a dielectric member opposite another main electrode thereby to form a shorter gap between the probe and the other main electrodes than that between the main electrodes. The starting device of HID lamps has a high frequency-high voltage (HF-HV) generator, the output of which is applied, directly or indirectly, to the probe. Accordingly, sure ignition and hot-restrike can be achieved by applying through the outer leads a superimposed voltage including the source voltage and the HF-HV.

Abstract: A discharge lamp lighting circuit system comprises a discharge lamp, an intermittent oscillation circuit, and an arrangement for controlling the energy supplied for lighting the discharge lamp with a high power factor. The intermittent oscillation circuit is energized by a low frequency a.c. power supply, i.e. a commercial alternating current power supply, for intermittently generating a high frequency high voltage in each half cycle of the alternating current of the low frequency a.c. power supply. By supplying the low frequency alternating current voltage and the intermittent high frequency high voltage to the lamp the discharge lamp is reignited in each half cycle of the a.c. of the low frequency alternating current power supply and the lit state of the discharge lamp is sustained by the low frequency alternating current voltage. The supplied energy controlling arrangement supplies the low frequency current to the discharge lamp during the operation period of the intermittent oscillation circuit and it also supplies the high frequency current generated by the intermittent oscillation circuit, effectively to the discharge lamp, whereby the discharge lamp is lit with a high power factor.

Abstract: A discharge lamp is ignited in every half cycle in its operating system including a discharge lamp operating circuit provided with a low frequency alternating current power source, a single winding type current limiter. The discharge lamp is connected to the power source through the current limiter and a series circuit including a high voltage output generator is connected in parallel to the discharge lamp. The high voltage output generator operates during the lamp operation for reigniting the discharge lamp. The voltage of the low frequency alternating current power source is set to less than the required reignition voltage of the discharge lamp during its operation, whereby the lamp current stabilizer size is minimized. Further, a filament preheating circuit is arranged to use current derived from the high voltage generator. The filament preheating circuit is combined with this operating circuit and so is a time delay for assuring a stable operation.

Abstract: A discharge lamp lighting device combines one or more discharge lamps and a backswing booster including essentially a power source circuit having a power source connected in series with a ballast and a high voltage generating circuit having an oscillation capacitor and a series circuit of a nonlinear inductor and a switching semiconductor. The supply voltage for the discharge lamp from the power source circuit is established to the extent permissible by the lower limit for sustaining an arc discharge of the lamp so that the terminal voltage of the ballast in the lamp operation is maintained as low as possible. The preferred backswing booster is of small size and an impedance circuit having a capacitor either with or without a bias coil is added to the high voltage generating circuit to produce a momentary high voltage. A leakage transformer or a voltage transformer with a tap or with a supplemental winding may be coupled to the power source circuit to establish a specified potential point from which voltage for the high voltage generating circuit is supplied to reduce the applied voltage during the lamp operation. An economical lighting device for the sequential ignition of two discharge lamps by means of a single high voltage generating circuit is disclosed.
