Title: Voltage measuring device
Inventor: ISHIWA EIJI
IPC: G01R19/10
Filed: 1980-12-26
Abstract: PURPOSE:To measure with high accuracy the difference between the values of two times measurements of voltage to be measured, by previously measure an error of a measuring device and then storing the error. CONSTITUTION:An amplifier 1 can be varied in two degrees of amplification, high and low i.e., in the amplification factors 1 and n. The gain of the amplifier 1 is set at 1, and the 1st voltage to be measured is supplied to the amplifeier 1 via a subtractor circuit 5. Thus the measured value including the errors of the amplifier 1 and an A/D conveting circuit 2 is latched to a latching circuit 6. This measured value is applied to the circuit 5 via a D/A converter 7 and a buffer amplifier 8. Under such conditions, the gain of the amplifier 1 is set at an n-fold value. Thus an n-fold value as much as the general error of a measuring device is delivered from the circuit 2 to be stored in a microprocessor 3. After this, the 2nd voltage to be measured is supplied and this output is stored in the processor 3. The processor 3 gives a subtraction to both inputs. In such a way, the difference between the vlues of two times measurements of voltage to be measured can be measured with high accuracy.

Title: Automatic generator for generated syntax
Inventor: NISHINO FUMITO
IPC: G06F17/28
Filed: 1986-08-09
Abstract: PURPOSE:To prevent the level of syntax from dropping and to cope with complicated syntax by correctly generating generated syntax by a machine. CONSTITUTION:A natural language sentence analyzer 2 and a natural language sentence generator 3 translate an original text inputted to a reader 1 for a parallel translation sentence as a parallel translation sentence. A natural language sentence comparator 4 compares the translation with a translation given to the reader 1. If they disagree with each other, the comparator 4 decides that there are errors in the generated syntax or its shortage. A generated syntax error recognizer 5 recognizes the syntax deriving the errors, and a generated syntax correcting device 6 corrects the generated syntax. A generated syntax inspecting device 7 inspects whether the corrected generated syntax correctly functions with respect to translations on a right answer file 9, thereby automatically generating the generated syntax.
