Title: Amplifier for optical reception
Inventor: SHIMIZU TAKAYUKI
IPC: H04B10/40
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To reduce the chip size of an amplifier for optical reception. SOLUTION: When an input optical signal is inputted to an amplifier for optical reception, a photoelectric conversion element 11 generates a corresponding current signal Iin and supplies the signal Iin to an input terminal IN. A transimpedance preamplifier 20, having a transistor 23 which functions as an amplifier and a feedback resistor 26, generates a voltage signal by converting the current Iin into a voltage by performing voltage amplification. A waveform- shaping circuit 40 shapes the waveform of the voltage signal and fetches an output voltage Vout from a voltage output terminal. When the modification of the waveform of the output voltage Vout is performed, the circuit constants of a resistor 42 and a capacitor 43 in the waveform-shaping circuit 40 are adjusted.  Since the circuit constant adjustment is not performed only on the capacitor 43, the chip size of the amplifier for optical reception can be reduced.

Title: Lighting system
Inventor: TANABE MASANORI
IPC: F21V8/00
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To prevent adverse effect of heat on a light diffusion plate or a prism sheet by installing the light diffusion plate on the top surface of a light guide plate for radiating light from a light source from the top surface and a second frame coupled with a first frame, and forming a gap between the light diffusion plate and the second frame. SOLUTION: When an electric energy is supplied, a light source 9 is lit, light comes in a light guide plate 4, is emitted from the top surface of the light guide pate 4, and radiated upward through a light diffusion plate 6 and a prism sheet 7. When the light source 9 is lit for a long time, heat is generated, and temperature of the whole lighting system is raised. The thin light diffusion plate 6 or the thin prism sheet 7 is bent or deformed by the influence of temperature. If they are closely arranged with no gap, they cannot deform, unreasonable force is applied, and troubles may be caused. Since the deformation is absorbed by a gap, the generation of troubles is avoided, and when temperature is lowered, the deformation is recovered to eliminate troubles.
