Title: Optical fiber cable
Inventor: IRI EIJI
IPC: G02B6/44
Filed: 1984-02-24
Abstract: PURPOSE:To reduce the strain of an optical fiber when tensile force and flexural force operate on a cable by stranding plural units around a tensile strength body which has a sufficiently large external diameter at specific intervals while inverting the stranding direction periodically. CONSTITUTION:A unit 2 is constituted by stranding, for example, six optical fiber cores 8 around a reinforcing material 7 in one direction and also covering the outside with a buffer layer 9. Each optical fiber core 8 is formed by coating an optical fiber 10 with a silicone resin coating 101 and a plastic coating 11. This unit 2 is stranded around the tensile strength body 1 which has the much larger diameter than the unit 2 clockwise, counterclockwise, clockwise... alternately at specific intervals. Consequently, even when tensile strength and flexural force operate on the cable, the strain of the optical fiber 10 is reduced to hold stable transmission characteristics.

IPC: G06K7/10
Filed: 1989-02-13
Abstract: PURPOSE:To improve the reading rate of a bar code by adding an accelerometer to a pen scanner and changing the frequency of a voltage control oscillator by using the output of the speedmeter. CONSTITUTION:The output of a photodetector 13 is amplified by an amplifier 15 and a waveform shaping circuit 16 shapes the waveform of the amplified output. Then, the output of the circuit 16 is supplied to a control circuit 17. An accelerometer 31 is provided in a container 11 and outputs vx, vy and vz corresponding to the respective components of the respective accelerometers are integrated in circuits 32-24 and converted to velocity outputs Ex, Ey and Ez corresponding to acceleration. Then, square mean value is calculated to these outputs in a circuit 35. For a voltage control oscillator (VCO) 19, the frequency is controlled by an output Ev of the circuit 35. Accordingly, the oscillation frequency of the VCO corresponds to the operation moving speed of the pen scanner and the oscillation output is operated as a reference signal corresponding to the waveform shaping output of the photodetector. Thus, the reading and recognizing rate of the code can be improved.

Title: Variable gain amplifier
Inventor: SATO HIDEAKI
IPC: H03G3/10
Filed: 1988-02-19
Abstract: PURPOSE:To increase the input impedance and to avoid the output operating point due to gain control from fluctuated by adopting differential circuit constitution and varying a resistance of a field effect transistor(TR) connecting sources of field effect TRs in differential pairs so as to control the gain. CONSTITUTION:The differential circuit constitution is adopted, where a 1st field effect TR Q1 and 2nd field effect TR Q2 are connected in differential pair, and sources of the 1st and 2nd field effect TRs Q1, Q2 are connected by a 5th field effect TR Q5. Since the drain-source voltage of the 5th field effect TR Q5 is always at nearly zero, the drain-source resistance is dependent on the gate voltage. The drain-source resistance is varied by controlling the gate voltage to vary the gain of the variable gain amplifier. Thus, it is possible to increase the input impedance and the output operating point is not fluctuated even if the gain is controlled.
