Title: Lighting device for fluorescent lamp
Inventor: OGAWA SOICHIRO
IPC: H01J61/52
Filed: 1991-02-14
Abstract: PURPOSE:To enhance a luminous efficacy as well as to lengthen the life of a lamp by sending preheating current to an electrode at the time of starting and during lighting a fluorescent lamp having the electrode composed of triple coils, and thereby making a preheating current value smaller during lighting than at the starting time. CONSTITUTION:Both the ends of a glass pipe 1 are provided with electrodes each of which is composed of triple coils 2 containing oxides 3 made up of a core with and of a primary coil. Mercury 4 and argon gas 5 are enclosed in the pipe 1. And when a fluorescent lamp starts operating, it is lighted with both the electrodes preheated by means of a lighting circuit having a preheat circuit, and sending preheat current is kept on during lighting. Since preheating current is therefore sent in addition to lamp current, it is possible to make a preheating current value during lighting smaller than that of starting time, so that brightness temperature can thereby be kept optimum. By this constitution, a luminous efficacy can thereby be enhanced, and the life of the lamp can also be lengthened.

Title: Phase locking circuit
Inventor: YAMAKAWA KUNIO
IPC: H03L7/107
Filed: 1987-01-30
Abstract: PURPOSE:To suppress a noise, and to facilitate a recovery to a locked state, by constituting a loop filter of two stages in case of a locked state, and constituting the loop filter of one stage in case of an unlocked state. CONSTITUTION:When a phase locking circuit is in a locked state, a lock detector 10 detects the locked state and opens a switch 7. As a result, a first loop filter 4 and a second loop filter 6 are connected in a longitudinal train, the capacity for suppressing an unnecessary frequency component such as an input noise, etc., increases, and a noise appearing in an output terminal 5 becomes small. Also, in case of an unlocked state, the lock detector 10 detects it and closes the switch 7. As a result, an output of the first loop filter 4 is directly inputted to a voltage control oscillator 2, a capture range is widened, and a return to the locked state is facilitated.
