Title: Bias circuit of transistor
Inventor: WAKAMATSU SHIGEMI
IPC: H03F1/30
Filed: 1982-07-22
Abstract: PURPOSE:To mount a transistor (TR) without adjustment and to improve the voltage utilization rate, by making it possible to setting the collector current and the voltage distribution between the collector and the emitter of the serial connection TR without having influecne with each other. CONSTITUTION:The voltage at a point 4 which is obtained by dividing the voltage of a power source 3 by resistances R9 and R10 is applied to the positive phase terminal of an operational amplifier Q5, and the voltage at a point 5 which is generated as the voltage drop due to the emitter current of a TRQ1 of a resistance R6 connected in series to TRs Q1 and Q2 is impressed to the opposite phase terminal through a resistance R11. Since the operational amplifier Q5 and the TRQ1 form an emitter follower circuit, voltages at points 4 and 5 are equal to each other. Consequently, a current Ic of the TRQ1 is determined by the resistance value and is not affected by characteristics of TRs Q1 and Q2. The voltage distribution between TRs Q1 and Q2 is determined by resistances R1' and R2' and is set independently of the current Ic.

Abstract: PURPOSE: To continuously perform a positive and negative nonlinear correction by a method wherein a sensing element converting a measured quantity into an electric signal is excited in proportion to a reference voltage to be obtained from the difference voltage between a variable voltage dividing point and a fixed voltage dividing point.  
     CONSTITUTION: The output of a bridge circuit 20 having sensing elements R g1 WR g4  converting a pressure et al into an electric signal is transferred to a receiving resistor 6 through a voltage/current converter 1. And further, a part of an output voltage is fed back to dividing resistors R 01 , R 02  and a constant voltage V z  is fixedly divided and along with this, the variable voltage dividing circuit is formed from a variable resistor R x  and from the difference voltage of these, a reference voltage VR is obtained, thus, the bridge circuit 20 is controlled so as to be proportional to the reference voltage VR. As a result, the relation between an output current and the pressure can be made an approximate linear state by setting the variable resistor RX properly. Thus, with a simple structure, positive and negative nonlinea correction can be made smoothly.

Title: Preamplifier integrated circuit
Inventor: SUZUKI HIROAKI
IPC: G11B5/02
Filed: 1984-06-25
Abstract: PURPOSE:To prevent disturbance of pictures at a head switching point by providing a terminal which adjusts the output terminal DC of a regenerative amplifier IC for the purpose of eliminating the DC offset of the regenerative amplifier which causes inversion phenomena, waveform distortion, etc. at the head switching point. CONSTITUTION:When the value of a resistance 17 is reedueced, the emitter current of a transistor TRQ12 is increased, and that of TRQ11 is increased, and the base potential of a TRQ13 is reduced, and the DC voltage of an output terminal 12 is reduced. When the value of a resistance R16 is reduced, the emitter current of the TRQ12 is reduced, and the base potential of the TRQ13 is raised, and the DC voltage of the output terminal 12 is raised. Thus, the ratio among resistances R16, R17, and R15 is changed to change freely the voltage of the output terminal 12 in both of positive and negative directions. Consequently, this circuit is used for, for example, an amplifier 3 of a conventional circuit to adjust the DC offset between amplifiers 3 and 4.

After the overlapped laser beams penetrate through a pinhole 12 and an optical filter 13, the phase shift of interference beams is detected by a detector 14. Through these procedures, the etching evaluation can be enhanced.

Abstract: PURPOSE:To produce the optical device having high accuracy by treating a forming surface so as to include hydrophilic parts and hydrophobic parts, then immersing the forming surface into a soln. contg. an optically active material and subjecting the same to a solidification treatment. CONSTITUTION:After the forming surface 102 is treated to include the hydrophilic parts and hydrophobic parts 101, the forming surface 102 is immersed into the soln. contg. the optically active material and is subjected to the solidification treatment. Namely, the aq. soln. sticks only to the hydrophilic parts when the material treated to have the hydrophilic parts and hydrophobic parts is immersed into the aq. soln. and is taken out. Since the circumference is hydrophobic, the aq. soln. stuck thereto is domed by surface tension. A material which solidifies in the aq. soln. is previously dissolved into the aq. soln. at this time, then the domed solids can be formed on the surface of the material by executing the solidification treatment. Lenses 104 are formed if the solids are transparent. The shapes having a transmittance distribution in the concentrical direction in plane are formed if the solids are translucent. The optical device having the high accuracy is obtd. in this way.
