IPC: C22B11/00
Filed: 1991-05-22
Abstract: PURPOSE:To almost completely remove impurities, such as lead by subjecting an iridium compd. contg. lead, etc., to reduction roasting, then treating this compd. with nitric acid. CONSTITUTION:The iridium compd. contg. the lead, etc., as impurities is put into a magnetic crucible and is subjected to a reduction treatment by blowing a hydrogen flame. The nitric acid (about 30 to 63% concn.) is then added to this iridium compd. and is heated to about 50 to 70 deg.C, by which the impurities, such as lead, are dissolved and extracted. The impurities, such as lead, are removed by filtration sepn. and the compd. is washed with pure hot water. The costly iridium is refined by the simple method in this way.

IPC: B41J2/44
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a fluorescent light emitting device which dispenses with an independently controllable control electrode and a negative voltage power source for the control electrode. SOLUTION: Two anode arrays 7, 8 each consisting of a plurality of anode dots 6 are provided on an anode substrate 2 of a device. Adjacent two anode dots 6, 6 in the anode arrays 7, 8 are commonly connected to an IC. Two cathodes 12, 13 are provided on the anode arrays 7, 8. An intercept electrode 20 is provided between the anode arrays 7, 8. A voltage for the cathodes 12, 13 is switched between 0 V or 40 V.

When the voltage of 0 V is applied to the cathode 12 at the let side of the intercept electrode 20, both of the potential differences between the cathode 12 and anode array 7 and between the cathode 12 and plane control electrode 11 become 40 V so that an electon generated from the cathode 12 reaches the anode dot 6.  The cathode 13 placed at the right side of the intercept electrode 20 is set to 40 V and both of the potential differences between the cathode 13 and anode array 8 and between the cathode 14 and plane control electrode 11 become 0 V so that an electron is not generated because there is not potential difference.

Abstract: PROBLEM TO BE SOLVED: To reduce the vibration of an optical box in the midst of rotating a rotary polygon mirror without causing cost rise by restricting the optical box on a supporting means for supporting the optical box by restricting force acting in parallel with the supporting surface of the supporting means. SOLUTION: The optical box 10 has supporting members 12 at four corners and fixed on a main body frame 20 being the spporting means of the optical deflecting scanner through a machine screw. An elastic body 21 holds the projecting part 15 of the optical box 10 by compressing force (restricting force) acting in a horizontal direction being parallel with the supporting surface. Thus, the central part of the optical box 10 is restricted by the frame 20. By restricting a part where amplitude is maximum when the optical box 10 is vibrated in such a way, the large vibration is prevented from occurring and the vibration of the optical box 10 is attenuated by the elastic force of the elastic body 21.  The extremely high-performance scanner where the vibration occurring in the optical box 10 while the rotary polygon mirror R1 is being rotated is effectively restrained and there is no trouble such as noise or the deterioration of image quality caused by the vibration of the optical box 10 is realized.

Abstract: PURPOSE:To improve the running speed with the less wear of a type belt by providing a running member running in the same direction as the belt does between the platen and the type belt in a type belt system impact type printer. CONSTITUTION:A belt 8 formed from a stainless sheet or as running member made of teflon or the like is provided between a platen 4 and a type belt 1, running in the same direction as the type belt 1 does and at a low speed. As a result, the relative speed between the type belt 1 and the belt 8 is smaller than that between the type belt 1 and the platen 4. In addition, when a print hammer 5 works, the type belt 1 contacts the plate 4 on the type side thereof through the belt 8 thereby reducing wear of the type belt 1. Thus, the printing speed can be improved with a higher running speed without lowering the print quality.

Abstract: PURPOSE: To intensify the black level in video signals and to improve the gradiation of an image by compressing the level of the video signals through an AGC circuit only when the video signals are higher or lower than a voltage of a preset width.  
     CONSTITUTION: Video signals are impressed upon a recording tube 49 through an amplifying transistor 12, a level adjusting circuit LV and amplifying transistors 26 and 29. If the resistance of a variable resistor 25 is adjusted, an AGC circuit CC is connected through a resistor 21 with the transistor 12. If the level of the video signals is higher than the voltage divided by resistors 17 and 18, a diode 22 is rendered conductive together with a diode 23, which is lower than the voltage divided by resistors 19 and 20, so that the level of the video signals to be impressed upon a recording tube 40 through the circuit CC is compressed when the video signals become higher or lower than a preset voltage. As a result, the image which is intensified in black and white levels is formed by the video signals, from which the unnecessary information such as the back ground or eging is eliminated, and the level of the video signals is controlled to fall within a preset range to produce an image having a satisfactory gradation.
