Abstract: PURPOSE:To prevent dielectric breakdown by a method wherein an overlying electrode and an underlying electrode constituting a MIM structure capacitor are connected by a wire of a conductive material in a process, and the wire is cut in the last process. CONSTITUTION:An underlying electrode 2 is formed on an insulator substrate 1 of sapphire by a liftoff method.

Title: Differential amplifier
Inventor: KANEKO YOSHIAKI
IPC: H03F3/45
Filed: 1988-11-01
Abstract: PURPOSE:To obtain a high input impedance required substantially for an operational amplifier by connecting an NPN transistor(TR) to the input side of each PNP TR and connecting a constant current source to the emitter of the TR. CONSTITUTION:Since an input differential voltage to NPN TRs Q3,Q4 connecting to each input of PNP TRs Q1, Q2 forming a differential pair is applied to the input of the PNP TRs Q1, Q2, that is, the base as it is, the normal differential amplification is implemented by the TRs Q1, Q2. Input bias currents IB+, IB- are decreased because a current amplification factor beta of NPN TRs Q3, Q4 is high (usually nearly 100). Thus, when the differential amplifier circuit is used for the input stage of the operational amplifier, a high input impedance is obtained.

Abstract: PURPOSE:To decrease the noises caused by the shift of a head carriage by attaching two guide rails through which the head carriage is moved and a step motor which drives the head carriage to a frame via a polymer sheet such as the silicone rubber, elastomer, etc. CONSTITUTION:Two guide rails 2 through which a head carriage 1 is moved and a step motor 3 which drives the carriage 1 are fixed to a frame 7 via a polymer sheet 6 such as the silicone rubber, elastomer, etc. This sheet 6 has the extremely large loss compared with the metallic materials like aluminum, stainless steel, etc., used to the motor 3 and the rails 2. Thus the vibrations of the sheet 6 are suppressed by the loss of the sheet 6 and not transmitted to the frame 7 easily. This decreases the vibrations of the frame 7 caused by the shift of the carriage 1.

Title: Shape variable optical element
Inventor: MATSUI NAOKI
IPC: G02B7/00
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce consumption of an expensive piezoelectric material and also reduce a production cost by using a part of an optical element main body or a part of a holding member as the piezoelectric material. SOLUTION: A concave mirror 10 comprises a main body 12 consisting of the piezoelectric material and conductive films 14, 16 on a surface and a back face of the main body 12. The conductive films 14, 16 are electrodes for polarization and for driving, however the conductive film 14 on the front surface is used in common as reflective film. If DC voltage is applied in the same direction as polarizing direction for the polarized concave mirror 10, whole body of the concave mirror 10 is enlarged in a direction of thickness (a direction expressed by an arrow T) and as the result thickness of whole body is increased. However, in this case, as main body 12 is joined to a hard round frame 15 in a peripheral part of a mirror, shrinkage of a mirror diameter D is hardly occurred due to prevention of shrinkage in a diameter direction.  Stress generated in this way is relaxed by shrinkage of curvature length L1, L2 of the mirror surface. Therefore, varying voltage applied to between the conductive films 14, 16 enables deforming a reflection surface 11 of the concave mirror 10.

Title: Ground-fault protecting circuit for current supply circuit
Inventor: HASUMI TAKASHI
IPC: H04M19/00
Filed: 1987-11-04
Abstract: PURPOSE:To suppress the output current of a current supplying circuit lower than a normal current value, by causing a constant-voltage controlling means to fix the voltage of a constant-current means to a constant voltage. CONSTITUTION:A Zener diode 24 is an element for causing a transistor(TR) 10 to make constant-current operations when a ground-fault occurs and, because of the diode 24, the base voltage of the TR 10 is fixed to a Zener voltage. When a ground-fault occurs and a fault current Iet reaches a fault detecting current value, the section between the collector and emitter of a TR 23 is conducted and an electric current is made to flow to the diode 24. Since the TR 10 is fixed to the Zener voltage by the operation of the diode 24, the TR 10 makes constant-current operation by the output current of a current supplying circuit. Therefore, the output current of the current supplying circuit can be suppressed lower than a normal current value.
