Title: Discharge lamp lighting device and lighting system
Inventor: KUBOTA HIROSHI
IPC: H05B41/24
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device operating without the use of element with high breakdown voltage. SOLUTION: A diode D3 is turned on, while a transistor Q1 is on to cause a drop of the cathode potential of a trigger stop diode D4, and electric charges on a capacitor C5 are discharged. Because the time constant of a resistance R1 and capacitor C5 at which the capacitor C5 is charged to cause a trigger element Z1 to be turned on, is set in a lag from the switching time of the transistor Q1, the capacitor C5 is kept in a condition of not being charged, as long as the transistor Q1 is in switching operations. When an inverter circuit 15 is in operation with the transistor Q1 in switching motion, the capacitor C5 is not charged, so that there is no need to equip the trigger stop diode D4 with a high breakdown voltage.

Abstract: PURPOSE:To make it possible to perform the clear detection of a target by avoiding the jamming of an arrival interference wave, by emitting the radar transmission signal of the polarized wave crossing that of the arrival interference wave from a radar antenna. CONSTITUTION:The characteristic analysis of a polarized wave is performed by such a method that the amplitude and phase of a horizontal component H are compared with a vertical component V as reference by a signal processing means. According to this result, the radar transmission signal generated in a transmitter 4 is synthesized to the polarized wave crossing that of an arrival interference wave at right angles by polarization wave synthesizers 10a-10n to be emitted from a radar antenna 1. Because the radar transmission signal strong in autocorrelation having a signal mode unaffected by jamming of the interference wave is reflected from a target to be received by a receiver 5 while guided thereto as mentioned above, the jamming of the arrival interference wave is avoided by a signal processor 6 and the detection of the target can be performed.

Abstract: PURPOSE:To control the travelling of a car effictively by arranging plural detecting coils to detect the vertical component of a magnetic field in the width direction of the travelling car, discriminating a detecting coil located on a guide line and controlling the operational direction in accordance with the set position of the detecting oil. CONSTITUTION:Detecting signal levels from the detecting coils 11a-11g to detect the vertical component of a magnetic field are sent to a comparator 21 respectively. The comparator 21 compares these detecting signal levels with a reference level, and outputs either a signal ''1'' or ''0'' to a position discriminator 22 when the signal levels are either more than the reference level or less than the reference level respectively. The discriminator 22 detects the shifted distance of the travelling car from the guid line by the signal status from the comprator 21 and sends the detected result to a steering angle adjustor 23. Consequently, the adjustor 23 decides the steering angle so as to compensate the shifted distance, the output signal of the discriminator 22, and drives a steering motor 25 positively or reversely through a motor controlling circuit 24.

Title: Call answering system
Inventor: NAKAMURA SEIZO
IPC: H04W84/02
Filed: 1985-04-23
Abstract: PURPOSE:To shorten a call answering time by allowing a frame which is sent from a master station to each slave station to have a selective call signal having a flag at a bit position corresponding to the call number of the slave station, and letting the slave station answer at timing determined according to the number of flags before or after the flag of the slave station. CONSTITUTION:When the selective call signal is applied to an input terminal 1, a frame synchronizing signal detecting circuit 3 detects a frame synchronizing signal 112 and actuates a counter. The counter 4 begins to count when the frame synchronizing signal is detected according to a clock, and sends a pulse to an AND circuit 7 when its counted number reaches a value set by a number setting circuit 5. If a selective call signal part 113 is '1' at this time, the AND circuit 7 sends its output to a call detection output terminal 8 to indicate the slave station is called and when the selective call signal part 113 to '0', no signal appears at the call detection output terminal 8.
