Title: Multistage luminous-intensity detecting device having fault display
Inventor: BITOU KENJI
IPC: G01J1/42
Filed: 1983-07-12
Abstract: PURPOSE:To ensure multistage luminous-intensity display and fault display of characteristic deterioration of photoelectric elements by simple constitution, by processing outputs of plurality of photoelectric elements by comparators, operating circuits, logic circuits, and the like. CONSTITUTION:Two photoelectric elements CalphaA and CalphaB are closely arranged in a light detector DEC and have the equal characteristics. Their divided voltages corresponding to the luminous intensities are processed by comparators C1A and C1B and C2A and C2B... having different reference voltages in a luminous-intensity comparing circuit part COMP. The levels of AND gates G1.1, G1.2... in a coincidence circuit AMC corresponding to the luminous intensities becomes high. The inverted output of the front stage are applied to corresponding AND gates G2.1, G2.2... in an encoder part ENC, and LEDs in a luminous intensity display part DP are lit. Meanwhile, the outputs of the detector DEC are processed by a operating circuit OPC and a judging circuit DSC, and the outputs of the comparators C1A and C1B... are processed by an exclusive circuit EX-OR. Illuminance-resistance characteristic deterioration is displayed on a fault display device AT.DP through an OR circuit ORC. Thus the multistage luminance-intensity display and the deterioration display of the photoelectric elements is ensured by the simple constitution.

Title: Pseudo-reverberation sound generating device for fm
Inventor: YAMAGUCHI KATSUMI
IPC: G01S7/52
Filed: 1980-09-10
Abstract: PURPOSE:To provide a pseudo-signal being similar to a reverberation sound of a sonar signal which is frequency-modulated, by a method wherein a signal, to which a frequency deviation pattern signal of a frequency-modulated sonar transmitting signal and a random numbers signal are added controls a frequency of a sine wave. CONSTITUTION:Patterns Sp, stored in a deviation pattern generating part 11, are read in turn, and the results and a random numbers Sr of a random numbers generating part 13 are added together by an adder 12 to obtain a signal Sa. The signal Sa indicates a frequency of each moment of a reverberation which changes in a complicated manner, and a period tp of the signal Sp corresponds to a pulse width of a sonar signal. This signal Sa reads a sine wave stored in each address of a sine wave generating part 16 via a variable frequency divider 14 and an address counter 15 to obtain a sine wave signal of a frequency deviation as shown in Fig. The signal is converted by means of a D/A converter and is added to a multiplier 5. Meanwhile, outputs of an envelope generating part 1 and a noise generating part 2 are multiplied by means of a multiplier 3 to be added to the multiplier 5. This obtains a mimic FM reverberation sound signal being very similar to a reverberation sound generated corresponding to a sonar transmitting signal.

Title: Light switch
Inventor: NAKAZATO KOJI
IPC: G02F1/35
Filed: 1990-05-16
Abstract: PURPOSE:To output signal light to different output ports by switching by adjusting the spread of the evanescent field of signal light, which is generated in a light directional coupling member, by the intensity of exciting light to switch the output ports of signal light. CONSTITUTION:When exciting light is not inputted, the spread of the evanescent field of signal light is relatively large is a light directional coupler 3, and consequently, signal light is easy to leak from an optical fiber 2 to an optical fiber 1, and it is taken out as an output A from the output port of the optical fiber 1. When exciting light is inputted, the spread of the evanescent field of signal light is relatively small in the light directional coupler 3, and consequently, light coupling is difficult to occur in the coupler part, and signal light is outputted from the optical fiber 1 as it is. Thus, the light switch operation is realized in accordance with turning-on/off of exciting light.
