Title: Direct-coupled amplifying circuit
Inventor: NAKAYAMA KAZUAKI
IPC: H03F3/45
Filed: 1982-08-20
Abstract: PURPOSE:To set the offset voltage accurately at zero, by setting the positive and negative power supplies under a floating state (or its approximate state) from an earth and detecting and amplifying the potential difference between the intermediate potential point and the earth to feedback said potential difference. CONSTITUTION:The currents I1 and I2 flow to resistances Rb and Rg1 as well as to resistances Rg2 and Rf in the directions shown by arrow marks respectively owing to the presence of the offset voltage of a differential amplifier (Q1 or Q2). The current I1 is equal to the current I2 since the power supply + or -VCC is floated, and I=(Vg1-Vg2)/(Rg1+Rg2) is satisfied for the current I. At the same time, the potential Vb at the middle point of the power supply is set as Vb=(Rb+Rg1)I and the DC output potential V0 is set as V0=-(Rf+Rg2)I respectively. While Vg1=Rg1Vb/(Rb+Rg1) is satisfied for the voltage Vg1 of an input terminal. Then Vg1 is equal to 0 if the resistance Rb is infinite. The current I is substituted for the above-mentioned equation of Vb, and Rb infinity  is taken into consideration. Thus Vg1-Vg2=0, i.e., Vg1=Vg2=V0=0 is satisfied. Then the DC output of a direct-coupled amplifier is set accurately at zero.

Title: Concentration detecting apparatus
Inventor: TANAKA TETSUO
IPC: G01N21/59
Filed: 1988-06-10
Abstract: PURPOSE:To set the voltage amplitude of a subtracting amplifier circuit at a sufficiently high value and to make it possible to detect concentration highly accurately by amplifying the difference voltage between a preset scale voltage and a detected voltage for the amount of transmitted light in the subtraction amplifier circuit. CONSTITUTION:An output voltage Vd of an operation amplifier circuit 10 becomes a voltage which is obtained by amplifying the difference voltage obtained by subtracting a scale voltage Vc (=Vn) from an output voltage Vm from an amplifier circuit 6. Therefore, a voltage amplitude, i.e. the ratio of R2/R1, can be set at a sufficiently large value, even if the output voltage range of the operation amplifier circuit 10 is equal to that of an amplifier circuit 25. When the concentration of developing liquid is changed from Dn to Ds, Vm is changed from 1.0 to 1.1V, and Vd changes from 0 to 2.0V. When Vm changes by 0.1V, Vd changes by as high as 2.0V. Therefore, accuracy in comparison and judgment in a comparing circuit 11 is increased.

IPC: F04C2/344
Filed: 1985-07-03
Abstract: PURPOSE:To facilitate the adjustment of discharge pressure by varying the thickness of the vane part of the blade of a vane pump. CONSTITUTION:The blades 36A-36F of a vane pump are formed so that each thickness of the vane parts 37A-37F is different at the top edge side and the basic edge side. Since the discharge pressure of the vane pump can be varied by varying the thickness of the top edge side vane parts 37A-37F, the blades 36A-36F having the vane parts 37A-37F having a variety of thickness are provided. Therefore, an arbitrary discharge pressure can be obtained by installing each blade 36A-36F having the vane part 37A-37F having each constant thickness onto the blade installation groove 35 of a rotor 27 in case of necessity.

Abstract: PURPOSE:To enable metal to be buried in an ultrafine recess by selecting an ionization rate and ion accelerating energy to increase the lateral sputter etching speed of the shoulder accumulated film of a substrate recess larger than the lateral growing speed due to impacts of ionized atoms or molecules to the accumulated film. CONSTITUTION:Molybdenum is used as a conductive material 40, and thermally melted by an electron gun 42 in a vacuum tank 45 to be evaporated. A voltage of several tens volt is applied from an arc power source 46 to an arc electrode 44 disposed near the gun to generate an arch discharge near the electrode 44, thereby ionizing part of evaporated molybdenum vapor. Molybdenum atoms 48 and ions 50 are incident to a substrate 52, but, in this case, the ions 50 are accelerated by an accelerating voltage applied by an accelerating power source 56 to a substrate holder 54 to impact the substrate 52, thereby uniformly accumulating the molybdenum in the groove. A sectional shape as shown in obtained even at -0.5kV of accelerating voltage by increasing the ion current density by a method of raising the ionization rate.
