Patent JP-H06196786-A (JP)
Title: Optical amplifier
Inventor: SAITO TOMOKI
IPC: H01S3/067
Filed: 1992-11-27
Abstract: PURPOSE:To provide an optical amplifier of low noise by reducing spontaneous emission light in and out of a signal light band which is emitted from the optical amplifier. CONSTITUTION:Input signal light 201 is amplified at an optical amplification section 100 and then the output light 202 is input into a spontaneous emission light eliminating section 101. At the spontaneous emission light eliminating section 101, only the light which is in the same polarization state as the signal light passes a polarization separating element 5 and then an output signal 203 is obtained. The polarization state of the signal light output from the optical amplification section 100 is a one-polarization state, however, the spontaneous emission light is in a random polarization state. So, at the polarization separating element 5, only a part of the spontaneous emission light having polarization components which agree with the polarization state of the signal light is allowed to pass through and components which are at right angles with the polarization state of the signal light is shut off. By this method, spontaneous emission light in and out of a signal band can be reduced and an optical amplifier of low noise can be obtained.

IPC: H04N5/18
Filed: 1993-11-25
Abstract: PURPOSE:To obtain an excellent clamping waveform reduced in sag or deformed synchronizing signal with a simple circuit configuration. CONSTITUTION:A video signal Se is applied to a charge/discharge capacitor via an input buffer A1. A charge/discharge circuit 32 charges a charge/discharge capacitor C1 when a SYNC tip level of the input video signal Se is smaller than a preset clamp level and discharges the charge/discharge capacitor C1 conversely when the SYNC tip level of the input video signal Se is higher than the preset clamp level. The SYNC tip level Lc of the video signal Se matches a clamp level Ld. In this case, a charging voltage Sg is given to a connecting point PF via a diode D and a variable resistor VR based on an ENV signal Sc. Thus, discharge by the clamping and the charging by the charging voltage Sg from/to the charge/discharge capacitor C1 are implemented and to improve the clamp signal waveform.

Title: Ink jet printing head
Inventor: KANEMITSU SATOSHI
IPC: B41J2/05
Filed: 1999-11-10
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet printing head detecting the flow state of ink from the supply of ink to the discharge thereof accurately at every ink pressure chamber by a simple device. SOLUTION: A pair of electrodes 19 are arranged in the vicinity of each heat generating part at every ink pressure chamber 14 (14i, 14n+1-14o+4) and, if the resistance value between the electrodes 19 becomes a resistance value 'H' at the time of the filling with an air bubble from a resistance value 'L' at the time of the filling with ink by the generation of a drive pulse signal to subsequently fall normally, the discharge and supply of ink are judged to be normal. When the falling of the resistance value during a period when the resistance value rises to the resistance value 'H' at the time of the filling with an air bubble to again become the resistance value 'L' at the time of the filling with ink is slow, it is judged that the contraction of an air bubble is slow, that is, ink is not discharged because of the clogging of a jet nozzle.  When the resistance value is held to the resistance value 'L' at the time of the filling with ink and does not become 'H', it is judged that the heat generating part 9 generates no heat by the disconnection of electrode wiring or the interiority of the heat generating part 9. When the resistance rises from the resistance value 'L' at the time of the filling with ink to the resistance value 'H' at the time of the filling with an air bubble and does not fall, it is judged that ink is not supplied to the ink pressure chamber 14.
