Title: Voltage measuring instrument
Inventor: NAGAI TOSHIAKI
IPC: G01R15/24
Filed: 1991-11-11
Abstract: PURPOSE:To accurately measure a terminal voltage by storing a conversion coefficient for converting the output value of a polarization analyzer into a voltage value at every terminal of an object to be measured. CONSTITUTION:A conversion coefficient is measured in advance by irradiating 10 the terminal of an object 21 to be measured with laser light. In other words, by successively applying 4 an arbitrary voltage Vlow and another voltage Vhi across transparent electrodes 25, the results of polarization analysis 30 are obtained at each voltage. By repeating such operation a plurality of times, the conversion coefficient of the terminal is calculated 41 from two reference voltage values and the results of the polarization analyses and the coefficient is stored 42. After calculating the conversion coefficients of all terminals, the calculated conversion coefficients are stored 42. Then, when the object 21 is mounted on a printed board 22, the refractive index of an electrooptic crystal 24 varies due to the terminal voltage applied across the crystal 24, since each terminal is electrically connected to light reflecting electrodes 26 through a contact mechanism 23. Since the reflected 26 light of the laser light irradiating the terminals is polarized due to the variation, the terminal voltage value is decided 40 by detecting 30 the polarized state of the reflected light. At the time of deciding the terminal voltage values, the conversion coefficients stored 42 at every terminal are successively read out and used.

Title: Control memory device
Inventor: AKASHI MINEO
IPC: G06F9/26
Filed: 1985-12-25
Abstract: PURPOSE:To shorten the processing time of a microsequence by deciding whether a microstep is shared or not when the address of a control memory device is specified and automatically outputting a shared microcommand. CONSTITUTION:By information stored in a sharing deciding information memory part 50, the output selection of microcommand information is automatically rearranged. If a different address is specified, the microcommand is read out of the same cell array of a control information memory part 40. Thus the microcommand can be read out in common out of the same memory cell, even if the address designation values in a control memory which may occur right after function branching are made to coincide with each other. Accordingly the number of microsteps can be reduced.
