Abstract: PURPOSE:To start the operation of the electromagnetic relay surely, by connecting the connection point between the transistor and the constant-voltage element and the light projecting and receiving circuit side of the current limiting resistance by the output of the light projecting and receiving circuit. CONSTITUTION:When the output of light projecting and receiving circuit 10 becomes ''H'', transistor 20 is turned on in a short time. The circuit between terminals 22 and 23 is short-circuited completely through diode bridge 21 by the collector and the emitter of transistor 20 which is turned on, and the residual voltage between terminals 22 and 23 becomes 0V approximately. Therefore, all of the voltage of DC power source 4 is applied to relay 3, and relay 3 starts the operation surely. When transistor 20 is turned off, transistors 15 and 16 are turned on immediately, and voltages are generated in both ends of Zener diode 17, and the residual voltage is generated between terminals 22 and 23. Though the current is reduced due to this voltage, the current is sufficient for relay 3 to hold the operation, and relay 3 continues operating.

IPC: G01R31/26
Filed: 1981-03-16
Abstract: PURPOSE:To obtain the highly efficient, highly reliable gain measuring device which is readily operated, by detecting the resonance of a circuit under test, fixing an oscillating frequency, and measuring the power gain of the transistor. CONSTITUTION:The oscillating frequency of a voltage controlled oscillator 11, wherein the oscillating frequency is controlled stepwise, is fixed to the resonant frequency of the circuit under test 6, which is formed by input and output tuning circuits, a reference transistor which couples said circuits, and the like. The input and output matching and tuning are performed in the circuit 6. When the reference transistor of the circuit 6 is replaced by a transistor to be tested, and a step voltage generator 14 is started, the detecting level of a broad band detector 13 is increased. The voltage is decreased after the circuit 6 has been resonated. Then the generator 14 is returned to the step immediately before, and the frequency of the oscillator 11 is readily and accurately fixed to the resonance frequency. The maximum power gain PG of the transistor is determined  by the equation I, based on the output level P1 of the oscillator 11 and the input level P2 of the detector 13. Thus, the readily operable, highly efficient, highly reliable gain measuring device is obtained. alpha in the equation is a matching loss of the circuit 6.

Title: Measuring method for yield point elongation
Inventor: MASUSE HIDEO
IPC: G01N3/06
Filed: 1986-02-21
Abstract: PURPOSE:To eliminate the need for manual operation and to take an accurate measurement by detecting automatically a yield point elongation end point as an inflection point where variation in load is large and measuring the yield point elongation on the basis of it. CONSTITUTION:Detectors 1 and 2 output and store a load and an elongation signal in a buffer device 3 continuously until a lock generating device 6 outputs a stop command when a load placed on a test-piece exceeds the yield point A and becomes equal to the load at the point A and a point E where the load increases a little bit from the point A is detected. The stop command outputted by the device 6 is inputted to a differentiating device 4, which reads the load value out of the device 3 and performs differential arithmetic operation to store the result. Then, an arithmetic device 5 searches for a differential value from the point E to the point A to find a point C where the load becomes minus for the 1st time. Then, the 1st detection of an inflection point is performed from the point E to the point C and when no inflection point is detected, a differential value set as an estimated differential value is made smaller than the initial value to perform the 2nd detection; and an inflection point detected by repeating the same operation until the inflection point is detect is regarded as the end point of yield point elongation.

Title: Encoding device
Inventor: KAMURA YUKARI
IPC: H04N19/134
Filed: 1991-02-08
Abstract: PURPOSE:To equalize the delay quantity of image data to that of audio data at the time of encoding. CONSTITUTION:Digital image data are encoded by a predictive encoding circuit 14 in encoding frame units with high efficiency and outputted as encoded image data. The encoded image data are stored temporarily in a buffer memory 15 with a write clock and read out as buffer image data at a specific read speed. A delay quantity calculating circuit 16 finds the delay quantity of the buffer image data as a mean delay quantity in units of N (N: integer larger than two) encoding frames predetermined according to the write clock. Then a delay control circuit 17 varies the delay quantity of a delay circuit 18 according to the input level of digital audio data on the basis of the mean delay quantity. Consequently, the audio data which is delayed corresponding to the delay quantity of the buffer image data are outputted as delayed audio data from the delay circuit 18. Those buffer image data and delayed audio data are multiplexed by a multiplexing circuit 19 and sent out as a multiplexed signal.
