Title: Data bus system
Inventor: SHIRAI HIDEAKI
IPC: H04Q9/00
Filed: 1990-10-20
Abstract: PURPOSE:To eliminate the possibility of malfunction by setting a dangerous period in synchronism recovery operation at the time of the transmission and reception of serial data in consideration of decision deviation of the start position of a stop time or stop period. CONSTITUTION:A maximum time setting means 4 such as a timer sets the dangerous period corresponding to the maximum time, which can be estimated as the decision deviation of the start position of the stop time or stop period, previously in consideration of the maximum time and a bus controller 1 performs control so that the transmission is started after the dangerous period. Consequently, even a terminal which starts operating at an earlier position than usual does not start transmission in said dangerous period, so the system never malfunctions.

Title: Discharge lamp lighting device
Inventor: NISHIZAWA YOSHIO
IPC: H02M7/48
Filed: 1989-10-31
Abstract: PURPOSE:To reduce heating of a switching transistor so as to suppress it to a certain level of heating, whereby the using of expensive transistor can be omitted by running a dc current regulated by current limit resistor, constantly in a secondary coil of a current transformer. CONSTITUTION:When a dc power source 10 is turned 'ON', a mono-stone self-excitation inverter circuit 16 is started and oscillation begins. Since a secondary coil 28b is provided on a ballast choke 28, voltage is generated on an end of the coil 28b, and the voltage is rectified and smoothed, while a condenser 44 is charged at a certain dc voltage. The dc current regulated at the dc voltage by a current limiting resistor 46 is flown into the secondary coil 30b of a current transformer 30. By running the dc current in the coil 30b, a dc magnetic flux is generated, whereby apparent saturating magnetic flux density of the transformer 30 is reduced, as well as an inductance value of the coil 30b. Since an effective value of the voltage generated on both ends of the coil 30b is also reduced, a base current of a switching transistor 26 is reduced according to the amount of the dc current running in the coil 30b.

Filed: 1991-10-31
Abstract: PURPOSE:To obtain a waveform which smoothly rises in the output of the voltage regulator by providing a circuit which precharges a phase correcting capacitor when powered ON. CONSTITUTION:This voltage regulator is equipped with a reference voltage block 8, an error amplifier 1, the precharging circuit 5, an output transistor(TR) 3, the phase correcting capacitor 4, and resistors 40 and 41. In this case, no charge is accumulated in the phase correcting capacitor 4 when the power source is turned ON, but the common source TR 51 of the precharging circuit 5 is OFF, so the phase correcting capacitor 4 is instantaneously discharged. The gate voltage of the output TR 3 reaches the same potential with the level of an input voltage Vin and the output TR 3 turns OFF. Then the error amplifier 1 supplies a current almost equal to that of a constant-current source 9 to the phase correcting capacitor 4, which is gradually discharged and becomes stable when balanced with the error amplifier 1. Neither of the output rising waveform 6, rounding nor a regulated output waveform is exceeded.
