Fluorescent lamp

An indicating device with a flat fluorescent lamp which comprises a fluorescent lamp having flat side surfaces and one or more indications formed on the side surfaces of the fluorescent lamp. The indicating device can be further provided with an ornamental frame which is attached to the outer periphery of the fluorescent lamp and a mounting base which is attached to one side of the ornamental frame and holds therein a discharge circuit including a stabilizer and a glow lamp for the fluorescent lamp.

Indicating device with flat fluorescent lamp

An ultrasonic oscillator device which has automatic gain control and which comprises a phase detector for detecting the phase difference between a load voltage and varying quantities indicating an operational condition of the load. The device further comprises a voltage control oscillator adapted to control an oscillating frequency through a direct current voltage corresponding to the phase difference. Further, the ultrasonic oscillator device is combined with a vibrator driven thereby and a small sized motor having a fan to forcedly cool the vibrator. The vibrator and the fan are accommodated in a housing, the size of which is made small, to produce a compact type machine.
