Title: Noncontact discrimination system
Inventor: OSADA MASAHIRO
IPC: G06K17/00
Filed: 1994-12-20
Abstract: PURPOSE: To extend the communicable distance by controlling the frequency of a carrier by a carrier frequency control part based on the frequency or the signal intensity of the return signal from a responder so that this frequency of the carrier is close to the resonance frequency of the responder. CONSTITUTION: The unmodulated carrier is transmitted from an interrogator 1, and the reverberation signal from a responder 2 is received by a reception part 14, and the frequency of the received reverberation signal is measured by a frequency measuring part 16 to detect the accurate resonance frequency of the responder 2. A variable frequency division circuit 19 properly selects the frequency division number based on the value of the resonance frequency of the responder 2 to generate the carrier signal whose frequency is closest to the resonance frequency of the responder 2.  Consequently, even if the inductance value or the capacity value of the coil or the capacitor in a resonance part 21 of the responder 2 is varied from the initial value because of the production error or the temperature characteristic, the carrier frequency of the interrogator 1 is equalized to the actual resonance frequency or the responder 2 to suppress the reduction of the communication distance.

Filed: 1990-11-22
Abstract: PURPOSE:To obtain nonlinear optical material having short absorption edge and large nonlinear optical characteristic by using a specific organic compound. CONSTITUTION:The organic compound shown in the formula I, 2-(p-chlorophenyl) imidazoline is used. Because this organic compound has short pi-conjugate length, the absorption edge is short and there is little fear to absorb output higher harmonics. It can be independently used, and on the other hand can be used as a composite compounded with (pi) electron conjugate series organic compound having electron releasing substituent and electron withdrawing substituent. Hereby, nonlinear optical material having high nonlinear optical characteristic and short absorption edge can be obtained.

Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of excessive power transmission output when power is supplied and when an input signal is cut by installing a switch means which changes over a control signal inputted to an amplifier to a signal from a feedback means when the level of the signal amplified by the amplifier is not less than a prescribed level. SOLUTION: A discrimination circuit 8 discriminates the level of the input signal of an amplifier 1 or a signal amplified by the amplifier 1 and outputs the discrimination signal of a high level or a low level according to whether it is more than a prescribed level or not. An AGC circuit 5 inputs detection voltage output from a detector 4 and outputs a control signal for controlling the feedback of a gain from the amplifier 1 in accordance with the voltage value. A switch 6 change over the control signal inputted to the amplifier 1 to a signal from the AGC circuit 5 when the discrimination circuit 8 discriminates that the level is above the prescribed level. Thus, the amplifier 1 does not output an excessive output signal since the gain is controlled to become that corresponding to prescribed output voltage.

Filed: 1988-12-16
Abstract: PURPOSE:To make the downflow of water drops good even when they condense on the outer surface and prevent the increase in the draft resistance of air flow and decrease in the coefficient of heat transfer by providing a water drainage face which communicates among flat plate fins in the direction of the steps on the downstream side surface by means of a flat groove of a flat plate fin. CONSTITUTION:A heat exchanger consists of a flat plate fin 7 which is provided with a plurality of steps of flat groove 8 which is constituted by cutting the front edge side in the air flow direction A of the fin 7 and a flat pipe 11 which is inserted into the flat groove 8 from the side face of the flat plate fin 7. A water drainage face 9 which communicates among the flat plate fins 7 in the direction of the steps is provided on the downstream side face that is downstream of the flat grooves 8 of the flat fin 7. When this heat exchanger with the fin is used as an evaporator and water drops condense on the outer faces, the water drops staying on the upper face of a flat pipe 11 are pushed by the air flow A and move to the downstream side and follows the water drainage faces 9 that communicate with each other in the direction of the steps. Accordingly it is possible to make good the fall of the water drops and suppress the increase in the draft resistance of the air flow A and decrease in the coefficient of heat transfer.
