Abstract: PROBLEM TO BE SOLVED: To make an automobile trademark clearly confirmable even in the nighttime by electrically connecting numbers of LEDs trimmed almost in the entire mark body, which is formed in a trademark shape, to the printed circuit on a printed substrate. SOLUTION: A void part 1a is provided on almost the entire part of a mark body 1 formed in the shape of an automobile trademark and numbers of LEDs 2 are trimmed therein. A printed substrate 3 is then formed in a shape conforming to that of the mark body 1. A printed circuit 3a is printed on the back of the printed substrate 3. The numbers of LEDS 2 are electrically connected together and fitted on the printed substrate 3 by running a pair of lead wires through a through hole from the obverse of the printed substrate 3 and soldering the end of the lead wire together with the printed circuit 3a. A nighttime lighting lamp wiring system or a brake lamp wiring system is electrically connected to the printed circuit 3a. Thus the trademark is lit when the brake panel is stepped on or when the light of a head lamp or the like is lit while running in the nighttime.

Title: Method for measuring polarization dispersion of single mode optical fiber
Inventor: YAMABAYASHI YOSHIAKI
IPC: G01M11/02
Filed: 1983-03-01
Abstract: PURPOSE:To measure the polarization dispersion of a single mode optical fiber simply and highly accurately, by reading the shift of frequency modulation to be imparted to a light source according to a scale provided in advance. CONSTITUTION:A length L of an optical fiber to be measured is measured. The maximum frequency shift DELTAf of frequency-modulated coherent light is variable. Said light is inputted to one end of the optical fiber to be measured as linearly polarized light, which forms an angle of approximately 45 deg. with respect to the main axis of double refraction of the optical fiber. The power of light outputted from the other end is observed through a polarizer. With the maximum frequency shift DELTAf being changed, disturbance is imparted, and the minimum value of the maximum frequency shift DELTAf when the change in optical power due to the disturbance becomes the minimum is obtained. The relationship between the amount of attenuation in a resistor attenuator 22 and the maximum frequency shift DELTAf is measured in advance. The maximum frequency shift DELTAf is obtained from the value of the resistor attenuator 22. Polarization dispersion D is computed by an expression D=2.405/(2pi.DELTAf.L).

The FET of a preamplifier is formed on the uppermost layer, I type GaAs layer 5, by performing ion implantation. An N electrode 12 of the photo diode is formed in a way that after part of the substrate is removed in the type of a via hole 11 from the back surface by performing a chemical etching, an entire surface evaporation is performed on the back surface. A P<+> region 16 is formed by diffusing an impurity in the window layer of the I type Ga0.7Al0.3As layer 4, and at the same time, is used as the electrical connection part to a gate part 9 of the FET of the preamplifier. Thereby, the parasitic capacity in the FET part is reduced because the N<+> conductive layer does not exist under the FET part.
