Title: Rare-earth element-doped optical fiber amplifier
Inventor: YOSHIDA HARUO
IPC: H04B10/293
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To obtain a rare-earth element-doped optical fiber amplifier which is provided with a signal generation function and which reduces a noise accumulation effect in a multistage cascade connection at a time when light is amplified and relayed by a method wherein an original signal is self-extracted, the signal is processed in such a way that its waveform is shaped or that its timing is adjusted and exciting signal light is modulated so as to be amplified in synchronization with the injection of signal light to be amplified. SOLUTION: A part of a light signal is taken out by an optical branching filter 30, and it is received with high sensitivity by a light-signal reception means 4 so as to be photoelectrically converted. The received signal which has been converted into an electric signal is timing-regenerated or waveform-shaped through an input drive-type timing filter 33 so as to be returned to the original signal. Exciting light from an exciting light source is modulated by the original signal. The modulated exciting light is multiplexed with the light signal by an optical multiplexer 12, and their multiplexed light is amplified through a rare-earth element-doped optical fiber 15 in synchronization with the injection of the light signal. When the light signal is multiplexed by the optical multiplexer 12, the timing of both is different.  As a result, an optical delay circuit 31 is inserted into a light signal line so as to make the timing agree.

Title: Dial numeral discriminating device
Inventor: TAKEUCHI KOICHI
IPC: H04Q1/30
Filed: 1986-10-08
Abstract: PURPOSE:To directly obtain numeral information from a terminal and to expand a service range by expressing the continuing time of an electrical impact vibration string as a function for a dialed numeral, previously determining the coefficient of the function, then deciding a dialed numeral from the measured continuing time of the string with the aid of the function. CONSTITUTION:A control circuit 11 skips the part A of the impact and vibration string, and surely grasps the top of a part B. When it is grasped, the circuit 11 renders a time count circuit 7 to start time counting, and grasps the end of the part B. Since under the same measuring condition the process that the part B electrically converges is almost constant regardless of the magnitude of dialed numerals, there is far less possibility that the point where termination is judged varies. When the circuit 11 recognizes the termination of the part B, it surely graspes the arrival of a part C. When the circuit 11 grasps the top of the part C, it stops the circuit 7 from counting time, and reads out a count-up as a measured value T3. The circuit 11 calculates each coefficient and decides the dialed numeral, and finally outputs a decided numeral through a circuit 6.

Title: Reflection-type optical encoder
Inventor: ITO YOSHINORI
IPC: H03M1/30
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain a reflection-type optical encoder which suppresses the generation of reflected light from parts other than a light reflection pattern for encoder. SOLUTION: A rotating disk 1 of the optical encoder is provided with a transparent substrate 2, and a metal vapor-deposited film 3 is formed on the surface 2a of the transparent substrate 2. A light-shielding film 4 which is composed of a photosensitizer is formed on the metal vapor-deposited film 3, the light-shielding film 4 is etched, and a light reflection pattern, for the encoder, which is prescribed by the part of the exposed metal vapor-deposited film 3 is formed.  When the surface of the rotating disk 1 is irradiated with light from the side of a light-emitting element, only the light with which the light reflection pattern 31 for the encoder is irracliated is reflected to the side of a light-receiving element, the light with which parts other than the pattern are irracliated is absorbed by the light-shielding film 4 and a light component which is reflected to the side of the light-receiving element hardly exists. Consequently, it is possible to prevent a bad effect that the S/N ratio of a detection signal is dropped due to the light reflected in the parts other than the light reflection pattern 31 for the encoder and a bad effect that light creeps to an optical element or the like in the circumference so as to generate a bad influence.
