Title: Large output current amplifier
Inventor: MULDER JAN
IPC: G11B5/012
Filed: 2002-06-25
Abstract: PROBLEM TO BE SOLVED: To solve the problem, when a normal maximum output current is doubled, of current consumption increasing in an amplifier, in which an output current Iout corresponding to input signals (Vin, -Vin) applied to two input terminals of the amplifier is transmitted to a load impedance RL connected between two output terminals. SOLUTION: Degenerate differential pairs are employed, in which four transistors (T1, T2, T3 and T4) which use a degenerate impedance Reg having the same value as the impedance RL as a feedback resistor, and control signals (-Vin/2, Vin/2), having a phase opposite to the phase of the input signals (Vin, -Vin), are applied to the upper pair (T3, T4) of the differential pair. Accordingly, the output current Iout of the amplifier can be doubled, without increasing the power consumption. The main purpose of the amplifier is to control the write head of a hard disk.

Title: Gate opening degree sensor for optical fiber and gate opening degree monitor for optical fiber using it
Inventor: FUKUSHI MORIHISA
IPC: G01G3/12
Filed: 2002-06-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide a highly reliable gate opening degree sensor for optical fiber requiring no power supply, and to provide a gate opening degree monitor using the sensor.  <P>SOLUTION: When a gate 20 descends, a flexible moving material 2 also descends and is accumulated on a saucer 3 from the part coming into contact with the saucer 3. When the material 2 is accumulated on the saucer 3, the weight on the saucer 3 increases and a beam 4 bends in accordance with the weight. Since the accumulated amount of the material 2 is proportional to the descending amount of the gate 20, the opening degree of the gate 20 can be indicated by processing the strain caused by the bending of the beam 4 as the change of the wavelength of reflected light by using fiber Bragg gratings 6a and 6b by means of a signal processing section. When the gate 20 ascends, the strain can also be indicated similarly. Since the fiber Bragg gratings 6a and 6b are used for the beam 4 constituting the gate opening degree sensor 1 which detects the opening degree of the gate 20, the sensor 1 is high in reliability and does not require power supply.  <P>COPYRIGHT: (C)2004,JPO
