Title: Signal amplifier circuit for 2/4-wire conversion circuit
Inventor: ASADA HIROSHI
IPC: H04M1/00
Filed: 1990-03-28
Abstract: PURPOSE:To easily adjust each amplification factor of a transmission signal and a reception signal while keeping the loop gain almost constant by connecting both inputs of a feedback loop formed to 1st and 2nd operational amplifiers via a resistor, connecting the resistor at an adjustable position to ground and constituting the resistor with two resistors whose resistance has a desired ratio. CONSTITUTION:A resistor 5, a sliding resistor 6 and a resistor 7 are inserted between an inverting input terminal of a 1st operational amplifier 1 and an inverting input terminal of a 2nd operational amplifier 2, and a slider 8 connecting to ground slide-contacts on the sliding resistor 6. When the slider 8 is turned upward with respect to the sliding resistor 6, a resistance between one terminal of the sliding resistor 6 at the 1st operational amplifier 1 and ground is increased, while a resistance between one terminal of the sliding resistor 6 at the 2nd operational amplifier 2 and ground is decreased. Thus, when the amplification factor of the 1st operational amplifier 1 is decreased, the amplification factor of the 2nd operational amplifier 2 is increased. Thus, while keeping the loop gain almost constant, the amplification factor of the transmission signal and the reception signal is easily adjusted.

Abstract: PROBLEM TO BE SOLVED: To properly perform a reading mode change caused by an unreadable error. SOLUTION: Firstly, a system controller 23 sets a disk motor 3 to a high- speed reading mode to rotate it at a high-speed, and outputs a control signal to a servo circuit 25 and a focus tracking servo circuit 31 to read a desired data of a disk 1 by a pickup 7.

Title: Self-illumination type road lighting
Inventor: IDO KENICHI
IPC: E01F9/576
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a self-illumination type road lighting rivet which does not project from a road face and efficiently radiates the rays of an illuminant from the surface of a transparent body to increase the visibility and obtains a small elevation angle of the radiating rays. SOLUTION: A transparent body 2 is fixed above a lighting rivet body 1 and an illuminant 3 is fixed below the transparent body 2. The illuminant body 3 is arranged to diagonally turn the optical axis 32 of the illuminating face 31 upward. The central part of the surface 21 of the transparent body 2 is made hollow to form an inclined face 24 at the inside face and an incident face 25 oppositely arranged against the illuminating face 31 of the illuminant 3 is formed at the lower part of the back face of the inclined face 24. The rays L of the illuminant 3 are led from the incident face 25 into the transparent body 2 and radiated from the inclined face 24. Since the radiating inclined face 24 of the illuminant rays is made hollow from the surface of the transparent body 2, it does not project from the road face G.  And the incident angle is made small by the inclination angle of the inclined face 24 and hence, total reflection does not arise and the elevation angle α of the radiating rays L can be made small.
