Title: Measurement of attached emitter quantity for fluorescent lamp
Inventor: MOMOTA ATSUKO
IPC: H01J9/04
Filed: 1986-03-25
Abstract: PURPOSE:To enable whether an emitter is attached to an electrode filament by a standard quantity to be accurately judged by measuring the frequency of an applied voltage at which the impedance of the electrode filament becomes maximum. CONSTITUTION:A reference lamp 1 is connected to an impedance measuring instrument 2 and the impedance of a standard lamp filament is measured by the instrument 2 by changing applied frequency. Curves indicative of the change in the impedance are recorded by a measurement result recorder 3 for every frequency while indicating the frequency on the axis of abscissa and the reciprocal of the value of the impedance on the axis of ordinate. Then, the lamp 1 wherein whether the quantity of an emitter thereof is proper being desired to be measured is connected to the instrument 2 and the curve indicative of the change in the impedance is recorded as in the case of the standard lamp while being superposed on the curve of the standard lamp. The frequencies at which the values of the impedance are maximum in the two curves are compared with each other by the two curves and whether the quantity of the emitter is proper is determined. A controller 4 controls the instrument 2 and the recorder 3 to realize an automatic measurement.

Therefore, a tracking phenomenon is hardly generated between the conductive parts even when the water splash.  In addition, the groove part 35 is formed between the conductive parts set as an unlike pole to each other at least, and is formed in a circumferential direction surrounding the conductive parts, so that the invasion of the water is hardly generated in the unlike pole conductive parts to surely prevent the invasion of the water on a lamp holder 36.

Abstract: PURPOSE:To ensure the reception of an input signal near a signal detection limit level by constituting a device so that the signal of definite amplitude is outputted if the pulse of the amplitude larger than a signal detection level exists among n-pieces of the pulses of a PAM signal. CONSTITUTION:The PAM signal which is PAM-modulated and is separated into the signal of a single frequency is converted into the definite amplitude by an amplitude converting means 1, and is outputted as a bipolar equiamplitude pulse. Besides, the PAM signal is compared with the signal detection level at its amplitude level of each pulse by an amplitude discriminating means 2, and is outputted as amplitude information to a signal detecting means 3. The signal detecting means 3 outputs the amplitude information as signal detection information if there is one piece, at least, of amplitude information discriminated to be larger than the signal detection level among n-pieces of the amplitude information. A signal confirming means 5 inputs a signal confirmation pulse from a signal confirmation period generating means 4 and the signal detection information, and fixes and holds the signal detection information at the point of time when the signal confirmation pulse is inputted, and simultaneously, sends it as signal control information to a signal controlling means 6. The signal controlling means 6 sends or stops sending the bipolar equiamplitude pulse to an output side according to the signal control information.
