Title: Method for measuring current-voltage characteristics
Inventor: HABU OSAMU
IPC: G01R31/26
Filed: 1991-07-26
Abstract: PURPOSE:To correctly measure output characteristics of an element to be measured even if the characteristics rapidly change by sequentially changing a set output voltage value or a current value according to an output from a signal source to the element. CONSTITUTION:Output voltage and output current limiting values of a voltage source are set to smart V, I respectively. Voltage and current flowing to an element to be measured in this state is a measured value A, and since a measured value B with step voltage V increased is in a voltage source state, it increments by step V to have a measured value C obtained. At the measured value C, the current reaches start I, so that current higher than the start I may not flow to the element and the voltage stops at voltage Vi. This state is determined to be a current limiting state, and a step I current limiting value is increased. With step V added to this measured value D, time current reaches the set output current limiting value am voltage Vj to have a measured value E obtained. Further with current increased by step I to measured values F, G, H, set voltage is reached at a measured value I, to which step V is added. Thus data other than the measured values A, B, D, I can be obtained to allow accurate measurement of output characteristics.

Title: Surface height measuring instrument, and exposing device using the same
Inventor: NARAKI TAKESHI
IPC: G03F9/00
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To surely measure the surface height of a substrate at a high speed by adjusting the width of slit light in accordance with the thickness or material of the substrate. SOLUTION: When the information on the thickness and material of a glass plate 16 is supplied to a main control section from an input section, the information is supplied to an arithmetic section after the information is once held in a storing section and the arithmetic section calculates the optimum width of slit light SL based on the information. Namely, the widths of the slit-like light transmitting sections 66a and 78a of slit plates 66 and 78 are calculated so that the reflected light rays of the slit light SL from the surface and bottom of the plate 16 cannot overlap each other. The arithmetic section then finds the optimum width of the slit light SL based on the widths of the sections 66a and 78a.  Therefore, the reflected light of the slit light SL from the surface of the plate 16 can be detected surely and, at the same time, the surface height of the plate 16 can be recognized surely. Namely, the maximum dynamic range which is not affected by the reflected light from the bottom of the plate 16 can be obtained and the measuring time of the surface height can be shortened.

IPC: H04L7/08
Filed: 1993-08-03
Abstract: PURPOSE:To attain the miniaturization of a device and low power consumption by reducing the hard amounts of a memory used for frame phase synchroniza tion. CONSTITUTION:A writing address and a reading address to a memory part 30 are compared by an address comparing part 20 for entire low-order frame signals.
