Abstract: PURPOSE:To prevent the precision degradation due to multiple reflection of responding waveforms of a tested element by installing a multiple reflection preventive circuit near an input terminal of an analogue comparator in a pin electronics. CONSTITUTION:A signal out of a timing generating apparatus 2 and a test pattern out of a pattern generating apparatus 1 are synthesized by a waveform formatter 3 and the output is supplied to an element to be tested 8 through a driver 5. The response output of the element 8 is converted into digital value by an analogue comparator 6 and a theoretical comparison test is carried out for the digital value and an expected value of the generating apparatus 1 by a digital comparator 4 at the time which the generating apparatus 2 indicates. To improve the time precision of the testing, a multiple reflection preventive circuit 7 is installed in an input terminal of the comparator 6. Multiple reflection can be eliminated by making the series-resistance value of the resistor, on- resistance of a diode and a transistor in the circuit 7 be equal to the characteristic impedance between a transmission wire of a pin electronics and the element 8. Consequently, a test for selecting the working speed and access time at high precision can be made possible.

Filed: 1979-01-31
Abstract: PURPOSE: To produce a stable glow discharge having high sputtering and oxidizing effects on a metal substrate, by exposing a metallic substrate to be treated in the positive column part of a glow discharge produced between electrodes for sufficient time.  
     CONSTITUTION: An Al substrate 1 and electrodes 2, 2 are set in a vacuum chamber, and a voltage is applied from a power source 3 across the electrodes 2, 2 to produce glow discharge. The substrate 1 acts on the electrodes 2, 2 as a bipolar electrode, therefore both the ionized O 2  and N 2  act on the substrate 1 as illustrated when the leak of the vacuum chamber can not be neglected. Consequently surface- oxydation effect is also shown. As a result, the treatment of, e.g., Al substrate by glow discharge is conducted effectively, hence the treatment is very useful for preliminary treatment for Se metallizing to produce a sensitive material for electron photography.

Abstract: PROBLEM TO BE SOLVED: To adjust the light quantity of the transmission light of a film from the side of a film adapter used by being mounted to an electronic camera, matched with performance on an electronic camera side. SOLUTION: When the release button 118 of the electronic camera 11 is pressed, a control part (A) 111 uses output from an area sensor 112 and measures the brightness of the film, that is the light quantity of the transmission light from the film. In the case that the measured light quantity is out of an appropriate light quantity range which can be coped with by an automatic exposure control part (AE) 111a, the control part (A) 111 transmits a light source light quantity adjustment command for specifying increase or decrease in light quantity so as to settle the light quantity of the transmission light from the film within the appropriate light quantity range to the control part (B) 211 of the film adapter 21.  In such a manner, by adjusting the brightness of a light source on the side of the film adapter 21 by control from the electronic camera 11 for receiving the image of a film frame, the light quantity matched with the performance on the side of the electronic camera 11 is obtained.
