Title: Optical receiving circuit
Inventor: ASAI TAKAHIRO
IPC: H04B10/293
Filed: 1981-03-17
Abstract: PURPOSE:To constitute an optical receiving circuit having the automatic gain control function of a high linearity, by changing the gain of an amplifier by plural switches and fixed resistances. CONSTITUTION:A photocurrent induced in a photodiode 1 is amplified by a low noise amplifier 2, and the output is taken out as the final output through an AGC amplifier 3, a buffer amplifier 6, and a pilot signal eliminating circuit 7. A part of the output of the buffer amplifier 6 is led to a signal amplitude detecting circuit, and a DC voltage proportional to the amplitude of the input signal is given to an AGC circuit 5. The AGC circuit 5 generates n-bit turn-on/off signal for gain control to turn on and off switches 130, 131-13n-1, and the resultant resistance value of resistors 120, 121-12n-1 is switched to 2 kinds of value by the combination of turning-on and off of these switches to set the amplification degree of the AGC amplifier to a prescribed value.

Title: Loop shape data transmitting device
Inventor: OTA KEISHIRO
Filed: 1987-02-20
Abstract: PURPOSE:To make it possible to diagnose the fault of a hardware by outputting data received in a slave station and then converting the outputted data into serial signals again so as to transmit to a master station. CONSTITUTION:When a signal l, for example, is received as a received signal, a carrier signal (n) whose frequency is twice that of the received signal is generated. At this time, a transmission buffer 37 outputs parallel transmission data (p) with a timing signal (m) outputted from a synchronizing carrier generation circuit. The received signal l is converted into a parallel received signal (q) in a serial parallel converter 39 setting the carrier signal (n) as a clock signal and the parallel transmitted signal (p) and the parallel received signal (q) are compared in a comparator 38 so as to output a coincidence signal (o). By setting the compared result as a decision signal (t), which is the AND of the coincidence signal (o) and a decision timing signal (s), then the signal (t) is inputted to a CPU 35, which examins the decision signal 35 and checks whether or not the transmitted data coincides with the received data transmitted from the slave station, thereby the fault of the hardware is diagnosed.

Title: Lens centering machine
Inventor: TSUBOI MASARU
IPC: B24B9/14
Filed: 1980-03-26
Abstract: PURPOSE:To reduce the time required for the centering process drastically by controlling the rotational speed of a lens turning motor according to the angle of rotation of a rotary shaft detected. CONSTITUTION:Projection members 14, 15 and 16 are arranged at a position of 20 deg., 100 deg., 230 deg. and 340 deg. to change-over the rotational speed of a lens 5 according to the rotational speed of a motor M. Here, for example, as a diamond tool 11 won't come in contact with the lens 5 before a driving shaft 8 turns by up to 20 deg. in the process, the lens 5 is rotated away. While the rotary shaft turns from 20 deg. to 100 deg., only centering is performed with a relatively fast rotation. This eliminates the need for adjusting the rotation of the lens 5 to the centering process requiring the lowest rotational speed thereby reducing the time for the centering process drastically.
