Filed: 1981-06-05
Abstract: PURPOSE:To make the oscillation stable, by designating in such a way that the (gm) when an external power supply is applied to an oscillation circuit at the application of power supply is not different from the (gm) when the circuit is driven with a regulated power supply. CONSTITUTION:When a power is supplied, a high level voltage is given to a voltage control terminal 12, an N type FET10 turns on, and a P type FET5 and an N type FET6 turn off, and a power supply voltage for a P type FET1 and an N type FET2 is an external voltage (VDD-VSS). In this case, current feedback is given with resistors 3 and 4 and the increase in the (gm) of an inverter operated as an oscillation circuit is less. When the oscillation circuit is at a normal oscillation state and a low level voltage is applied to the voltage control terminal 12, and when the N type FET10 turns off and the P type FET5 and the N type FET6 turn on, a voltage applied to the FET2 comes from an output of a regulated power supply 11. Although the voltage is lower than that at the application of power supply, since the P type FET5 and the N type FET6 turn on, and the (gm) of the inverter operated as the oscillation circuit can be made equal to the (gm) at the application of power supply.

Title: Method for correcting alignment error
Inventor: ICHIKAWA HAJIME
IPC: G01B9/02
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To correct an alignment error accurately and conveniently by fitting information obtained through interference measurement optimally to a surface represented by polar coordinate format. SOLUTION: A polar coordinate system γ, θ, ϕ is represented by a coordinate conversion formula of orthogonal coordinate system x, y, z. When the center of sphere of a surface to be inspected r=R (constant) is located at shix, shiy, shiz with respect to the origin of coordinate 0, 0, 0 at the center of sphere of the measuring wave front of an interferometer, the surface to be inspected can be represented by an expression (x-shix)<2> +(y-shiy)<2> +(z-shiz)<2> =R<2> . The expression is employed along with a coordinate conversion formula for making a conversion into polar coordinate format r=f (R, shix, shiy, shiz; θ, ϕ). Furthermore, the xy coordinate values of interterometer measurement data xi, yi, Δrij obtained for every measurement pixel l, j by each CCD from a variation [dr] of [r] for the shift of alignment represented by a microdisplacement of variables are converted according to the conversion formula into θϕ coordinate values and then the partial differentiation coefficients are calculated for each pixel thus determining the shift.

Title: Semiconductor integrated circuit
Inventor: TAKANO SATOSHI
IPC: H01L21/8236
Filed: 1984-04-27
Abstract: PURPOSE:To prevent malfunction by providing a level shifter which lowers the ''L'' of a signal to a negative potential in front of a normally off type MESFET of gallium arsenic with a uneven threshold value so that the MESFET turns off completely when an input signal to its gate is at ''L''. CONSTITUTION:When a signal with the ground potential is inputted to the level shifter C, a node 26 is held at -phiB by setting Vss to a negative potential below -phiB. At this time, a normally off type MESFET23 turns on and the potential at an output terminal OUT is lowered to the negative level -phiB. This level shifter C is connected to a decoder circuit consisting of an inverter A and an NOR circuit B and then the ''L'' of the output signal of the inverter A is lowered by the level shifter C from the ground potential to a negative potential and inputted to the gate of a normally off type MESFET4. Therefore, FETs 4-6 are turned off completely when inputting ''L'' and this line is prevented from being unselected selectively.
