IPC: H04B10/61
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To obtain a light output signal having a pulse width shorter than the pulse width of an electric pulse signal for modulation. SOLUTION: The light output signal having a short pulse width is obtained by modulating a light input signal while using a first electric pulse signal for modulation A in a first light modulation part 11 and by modulating the modulated light input signal while using a second electric pulse signal for modulation B in a second light modulation part 12. In this case, the electric pulse signal for modulation inputting from an input terminal 19 is branched into two signals by a spitter 13 and the electric pulse signal of one side is made to be the first electric pulse for modulation A and the branched electric pulse signal of the other side is delayed by a delay unit 14 to be made to be the second electric pulse signal for modulation B. Then, the pulse width of the light output signal is changed by changing the delay amount Δt by the delay unit 14.

Title: Display device and its driving method
Inventor: TAKAHASHI SHINYA
IPC: G02F1/133
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of crosstalk. SOLUTION: While a correction signal is at L, switches (S1, S4) are ON and switches (S2, S3) are OFF, so that +VR or -VR is outputted as a scanning voltage pulse. While the correction signal is at H, the switches (S1, S4) are OFF and the switches (S2, S3) are ON, so that a potential -VC or +VC having the opposite polarity from a nonselect potential (VM) is outputted as a scanning voltage pulse. Consequently, a select pulse is fixed at a potential having the opposite polarity from the nonselect potential (VM) in the correction period and a select pulse falls steeply, so that waveform distortion is corrected.

IPC: F24J2/48
Filed: 1983-03-14
Abstract: PURPOSE:To obtain the heat radiating member which is excellent in heat radiating property and heat resistant property and which is resistant against physical impacts by a method wherein a chromium compound is used to form the heat radiating member. CONSTITUTION:A heat radiating member comprises a base provided on its surface with a chromium oxide layer which is produced as a result of conversion of the chromium compound by heating. To obtain the heat radiating member, a heat radiating material as the base having a predetermined configuration is dipped into a reacting liquid consisting mainly of the chromium compound and then the material is heated to make a layer containing chromium oxide. Thus it is possible to obtain a desired surface condition for the heat radiating member by repeating the above processing cycle several times. In this case, it is effective to apply a surface treatment on the base heat radiating material before it is dipped into the reacting liquid, for example, metal plating, flame spraying, or the like.
