Abstract: PURPOSE:To construct a high-resolution light signalling device by a method wherein a plural number of LEDs are arrayed at a fixed interval on a substrate and selectively subject to an electric signal and one end of each optical fibre scope is faced at a light emitting surface and the other ends are gathered in array. CONSTITUTION:Original informations on a script to be copied are converted to electric signals and fed to a light signalling device 3a to convert to light signals, which are faced at a surface of a light-sensitive drum 1 via a condenser lens 3b. The device 3a is equipped with an array of a mesa-type LED11 on a substrate 10. An LED11 has a P and N type Ga1-xAlxAs layers, 11a and 11b respectively, on a GaAs substrate 10, and an electrode 12 having a hole 12a is built on the layer 11b to constitute a light emitting surface. A lead wire 13 is connected with the electrode 12, and a lead wire 15 is connected with a common electrode 14 on the back surface of the substrate 10. Electric signals are selectively fed into lead wires 13 and 15 to activate appropriate LEDs. One end of optical fibre bundle 17 is in face of output terminal of LEDs and the other end forms a collected light output terminal 16. With this construction, the resolution is improved, and it is not affected with some defective LEDs and the production yield of the device is enhanced.

IPC: H01J31/15
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To provide an anchor structure that can suitably control resonance of a filament shape negative electrode for a fluorescent character display tube. SOLUTION: An anchor structure of a fluorescent character display tube is composed providing with a plurality of arm sections 36 that apply mutually different tensions of a plurality of negative electrodes 28.

Title: Video signal amplifier circuit
Inventor: AMANO RYOSUKE
IPC: H04N5/243
Filed: 1991-06-14
Abstract: PURPOSE:To keep an output dynamic range constant while preventing adverse effect due to saturation of the amplifier circuit. CONSTITUTION:An input video signal from a terminal 12 is fed to a base of a PNP transistor(TR) 12. A constant current source 13 is connected to an emitter of the TR 12 and an emitter output is fed to an inverting input terminal of an operational amplifier 15 via an input resistor 14 whose resistance is variable. An output of the operational amplifier 15 is extracted through a terminal 17 and fed back to the inverting input terminal via a negative feedback resistor 16.

Title: Error rate monitor device
Inventor: OGAWA KAZUO
IPC: H04L27/18
Filed: 1979-12-27
Abstract: PURPOSE:To make high-frequency circuit parts needless to make the circuit scale small, by adding one discriminator to the detecting circuit for phase step out to discriminate presence or absence of noise margin each time. CONSTITUTION:Discriminator 7 is added to the output of circuit C2-2 which operates absolute values of two inputs of the last stage to output the difference between these two absolute values. Signal (16) is integrated by low-pass filter 2-2, and it is discriminated whether the integral value is larger than a prescribed value or not, thereby deciding phase step out. Threshold voltage Vt is used to discriminate signal (16) directly by discriminator 7, thereby discriminating whether noise margin exists sufficiently or not. Then, pulses of output signal S3 of discriminator 7 are counted to count the degree of presence of absence of noise margin. As a result, the error rate is estimated at every certain time.
