Title: Generating method for holographic optical element
Inventor: AMAKO ATSUSHI
IPC: G02B5/32
Filed: 1988-01-27
Abstract: PURPOSE:To execute the blaze conversion of a hologram by a simple method by bringing at least one spherical wave to very small displacement along an optical axis line or in a plane being orthogonal to an optical axis in the course of exposure. CONSTITUTION:In the course of an interference exposure, a light source Q of a spherical wave S is moved by a prescribed quantity in a prescribed direction. Therefore, an entrance lens 17 which has fixed a piezo-element being well-known itself is used as a spherical wave light source. In such a way, by moving one generated wave (spherical wave) S in the course of exposure, as for a hologram generated by a two-luminous flux interference exposure, its contrast drops, and an action effect being equal to a blaze conversion is shown. That is, the diffraction efficiency becomes high. In such a way, a complicated equipment and a great deal of manhour become unnecessary, and also, a technique of a high level is unnecessary and the blaze conversion of a surface relief type hologram can be realized.

Inventor: YOSHIDA SHINJI
IPC: H01L21/822
Filed: 1984-01-30
Abstract: PURPOSE:To remove the dispersion of the resistance value and to get exact value of it by a method wherein one of the impurities which becomes a doner or an acceptor is doped simultaneously to a series resistor part when semiconductor resistors of the inverse conductive type are connected in series to each other and is made as a semiconductor resistor element. CONSTITUTION:When a resistor is formed with the designed value R, it is very rare that the total value of the P type resistor value RP and the N type resistor value RN is the same to R. When the short of the resistance value r at this time is indicated r=R-(RP+RN)<0, B ions are injected with the dose volume of phiB, and the resistor value R is made R=PP1+RN1, RP1=RP+alphaBphiB, RN1=RN+betaBphiB. Namely, R=RP+RN+(alphaB+betaB)phiB, when the resistor value fluctuation rate of the P type resistor and the N type resistor are made alphaB and betaB respectively, and it will be all right to obtain the condition of r=(alphaB+betaB)phiB. Because B is a P type impurity here, alphaB and betaB will be indicated alphaB<0, betaB>0. The same result will be obtained when P ions are injected in place of B ions.

Abstract: PURPOSE: To avoid the quick gain change of an operational amplifier and to reduce the amplitude voltage of ringing by continuously turning on/off the circuit between the inverted input terminal and the output terminal of the operational amplifier in the refresh period. CONSTITUTION: When switches S1 and S2 are temporarily turned on by a clock ϕr at the time of switching from turning-on/off to turning-off/on of a set of switches X10, X10', X20, and X20', a set of switches X11, X11', X21, and X21'..., electric charge remaining in capacitors C10, C11... and C20, C21... is completely refreshed not to have a bad effect upon following band frequency determination. Switches S1 and S2 are turned-on/off by the high-speed clock in the period when they should be turned on. Since a switch takes action equivalent to a resistance component, the quick gain change of the circuit is suppressed even if switches S1 and S2 are continuously turned off by the end of the refresh period, and therefore, the voltage amplitude of ringing brought about at this time is reduced.
