Title: Flash photographing device
Inventor: TANIGUCHI NOBUYUKI
IPC: G03B15/05
Filed: 1983-06-07
Abstract: PURPOSE:To reduce the probability of malfunction by detecting the prescribed proportion of the reflected light from an object caused by flash light emission and an exposure, and outputting two kinds of light emission stop signal, and providing a terminal which transmits these signals to flashes. CONSTITUTION:In case that two flashes LFP1 and LFP3 emit light successively, the first light emission stop signal is outputted from a control circuit BOC when a measured value of the reflected light from the object attains a prescribed proportion, and the second light emission stop signal is outputted from the circuit BOC when it reaches a correct exposure. Ia mode other than this successive light emission mode, only the second stop signal is outputted. The terminal which transmits light emission stop signals from a signal output means to flash devices is provided additionally. Thus, it is unnecessary to provide plural terminals for transmission to flash devices, and the difficulty of arrangement of terminals due to restrictions of the connection part between a camera and flash devices is eliminated. Further, the probability of malfunction between the camera and flash devices is reduce to improve the reliability.

Title: Eddy current flaw detector
Inventor: HIBINO TAKASHI
IPC: G01N27/90
Filed: 1979-08-11
Abstract: PURPOSE: To ensure an independent processing for both the amplitude and the phase of the signal component, by connecting the output voltage of the bridge circuit to the phase regularizing circuit via the amplitude regularizing circuit and then obtaining the impedance variation of the bridge circuit.  
     CONSTITUTION: When the impedances of coils L 1  and L 2  of bridge circuit 101 vary, a difference is caused between the phase and the amplitude of the voltage between terminals A and B. For the amplitude, the voltage between terminals B and C is rectified by rectifiers 13 and 12 of amplitude regularizing circuit 102, the differential voltage is extracted via subtractor 14, and then this differential voltage is used to control automatic gain controller 11 to secure the equal voltage amplitude between terminals B and C. For the phase, phase wave detector 17 of phase regularizing  circuit 103 delivers the DC voltage proportional to the phase difference between the  signals of terminals B and D having an equal amplitude, and thus phase circuit 15  is controlled to give a control to secure the same phase for the voltage of terminals B and D each. Accordingly, output 19 of subtractor 18 becomes zero with a gentle change of the impedance, and then the signal of the sudden impedance change due to the flaw detection is delivered.

Filed: 1987-04-25
Abstract: PURPOSE:To reproduce a normal clock signal in synchronism with a specific pattern even if there is a flaw in a position close to the period of the signal of the specific pattern recorded in a recording medium by adding a pattern coincidence detection circuit that outputs a phase comparison permission signal. CONSTITUTION:The pattern coincidence detection circuit 15 detects the approximate coincidence between the pattern of a reproduced signal from a disk 1 supplied through a binarization circuit 13 and that of the signal of the specific pattern, and the detection circuit 5 outputs a phase comparison permission signal. However, in case there is a flaw in a position close to the period of the signal of the specific pattern, the phase comparison permission signal is not outputted. Therefore, the action of the phase comparator 21 of a PLL circuit 30 to compare said output with an output from an edge detection circuit 16 is not executed. Accordingly, the lock on the PLL circuit 30 is not released, and the reproduction of a normal clock signal in synchronism with the signal of the specific pattern can be executed.
