Abstract: PURPOSE:To increase the range of input converting voltage, by detecting a difference voltage between the reference voltage and the input voltage with a correction given to the reference voltage and holding the reference voltage for a prescribed period to add an automatic scale correcting function. CONSTITUTION:An input device 31 samples the voltage of a reference power source 29 and holds it after dividing it into holding capacities 35 and 36.

Title: Method and apparatus for detecting force
Inventor: UDAGAWA TSUGIO
IPC: G01L1/10
Filed: 1984-04-20
Abstract: PURPOSE:To broaden the detecting range of an external force, which is applied to a piezoelectric body and to make sensitivity uniform, by detecting the frequency of an applied voltage, whose phase angle with respect to the terminal voltage of the piezoelectric body is changed to a large extent. CONSTITUTION:Under the state where an external force is not applied to a piezoelectric body 1, a phase angle theta in a phase angle setting circuit 6 is set at theta1. A frequency F from a variable frequency oscillator 4 becomes a stable state at a frequency f0 so that a point P1 is obtained on a curve X0. Under this state, the external force is applied to the piezoelectric body 1 and the phase angle characteristic is changed into a curve X1. Then the output from a differential amplifier circuit 7 is changed and the oscillating frequency F of the variable frequency oscillator 4 is changed from f0 to f1 and stabilized at a point P2 corresponding to the phase angle theta1. The frequency change during this period is obtained by measuring the output e0 from the differential amplifier circuit 7, and the applied external force can be found.

Title: Graphing method for convertible debenture
Inventor: TAKEUCHI HIDEO
IPC: G06C3/00
Filed: 1980-06-11
Abstract: PURPOSE:To read the timing of less-risk and efficient investment on a graph, by representing graphically the price of convertible debenture while comparing it with an investment estimated value and a parity price. CONSTITUTION:A (parity price divided by  investment estimated value) 5 is graphed on the X axis, and a (convertible debenture price divided by  investment estimated value) 6 on the Y axis respectively. A straight line 7(Y=X) shows (parity price = convertible debenture price). The minimum price of convertible debenture, however, is equal to the investment estimated value actually, so Y=1 is considered to be the minimum value on the Y axis, so that while Y<=1 is discarded on the Y axis, a (convertible debenture price divided by  investment estimated price -1)8 is shown graphically on the Y axis. The left-to-right movement of the graph means an increase in parity price, and the down-to-up movement an increase in convertible debenture. For safety, comparison with values on the X axis is made, and for efficiency, comparison with a straight line 9(Y=X-1) is made.

IPC: H01J37/147
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To reduce glitch noise of a D/A converter by performing lithography lithography again by setting lithographic position data of shape electron beam lithography and follow-up data again, when a sample stand movement amount during lithography on a sample stand which moves continuously tends to deviate from a preset allowable range. SOLUTION: An allowable range of movement amount in lithography is preset in a comparison means 10 for movement amount in lithography. When movement amount of a sample stand 19 exceeds an allowable range, deviation alarm is emitted to a sub-deflection control circuit 7 by the comparison means 10, and an interruption signal is emitted to a blanking control circuit 11 which controls irradiation time of electron beam for lithography simultaneously. The blanking control circuit 11 immediately interrupts present lithography. The sub-deflection control circuit 7 modifies position data of lithography. A lithographic position is moved to an allowable range by movement of lithographic position data in this way. Then, pattern generation by the blanking control circuit 11 is started again.
