Title: Device for detecting ejection of liquid
Inventor: SUGITA YUKIO
IPC: B41J2/01
Filed: 2002-03-27
Abstract: <P>PROBLEM TO BE SOLVED: To judge ejection of a liquid by a simple structure of a device without wasting liquid.  <P>SOLUTION: An optical beam 21 is projected to a surface 23 of an ink on an ejection nozzle 6 from a light emitting device 22 of an ink ejection detecting device 12. At the same time, an ink ejecting means 9 is operated to vibrate the surface 23 of the ink. By the vibration, a reflection angle θ of a reflected light of the optical beam 21 is varied by virtue of the vibration, and then a measured output of a photodetector 25 is varied. The output is amplified by an amplifier 34. A main controller 31 judges that clogging of ink occurs when the amplified value is not greater than a threshold value It and judges that it is normal when the amplified value is not less than the threshold value It. As it is needless to eject the ink so that the ink is not wasted, it is possible to reduce the running cost of the device.  <P>COPYRIGHT: (C)2003,JPO

IPC: B65G17/22
Filed: 2002-03-27
Abstract: <P>PROBLEM TO BE SOLVED: To solve failure due to high speed operation of a loop type conveyer line.  <P>SOLUTION: When a conveyed body 2 conveyed at a low speed on the loop type conveyer line 1 is caught by a catching means 19 and a belt 17 is moved, the conveyed body 2 is conveyed at a high speed. When the belt 17 is stopped and the catching means 19 is released at the time when the conveyed body 2 is conveyed to a predetermined position at the high speed, the conveyed body 2 is conveyed again at the low speed on the loop type conveyer line 1. As a result, the loop type conveyer line 1 operates at the low speed as it is, so that a failure due to the high speed operation, namely a failure due to vibration or noise during driving and a failure of fine acceleration operation, can be solved.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a wavelength multiplex communication system, capable of performing normal wavelength multiplex communication, making insertion losses uniform, and reducing cost of the overall system.  <P>SOLUTION: In this system, first and second multiplexer-demultiplexers which face each other are connected by an optical fiber cable. Wavelength filters are cascaded to the first multiplexer-demultiplexer in the order, from λ4 through λ2, and wavelength filters are cascaded to the second multiplexer-demultiplexer in the order reverse to that in the first case, i.e., from λ1 through λ3. In each multiplexer-demultiplexer, a light-receiving section is connected to the former filters near the cable, and a light-transmitting section is connected to the latter filters. With this constitution, optical signals transmitted between the first and second multiplexer-demultiplexers are relayed by almost the same number of wavelength filters, and thus the insertion losses influenced by transmission of the optical signal through the wavelength filters can be made uniform.  <P>COPYRIGHT: (C)2004,JPO
