Title: Repair of lining of wall of coke oven
Inventor: MATSUO MASATAKA
IPC: F27D1/16
Filed: 1978-05-08
Abstract: PURPOSE: To improve adhesivity of a lining layer by flame spraying and to bond the layer to a wall of a coke oven, by removing attached carbon, etc. from the wall surface of the coke oven through exidizing flame of a flame gun, followed by flame spraying of refractory powder.  
     CONSTITUTION: After coke is taken out from a coke oven by a coke pushing machime, carbon and tar deposited on a repairable part of a wall of the coke oven is removed by oxidizing combustion of a flame gun. The wall is coated with fefractory powder by flame spraying to form a lining layer, which has improved adsecitity. When the refractory powder is applied by flame spraying to the wall of the coke oven while it and hot bed are maintained at a temperature of not less than 400°C by oxidizing flame in removing carbon, the linining layer has improved adhesivity.

IPC: G05D3/12
Filed: 1983-03-29
Abstract: PURPOSE:To stabilize the running of a moving table, by adjusting the intensity of the driving force of both driving devices facing to the moving table in accordance with the ratio of distances between the moving table and the driving devices. CONSTITUTION:A moving guide 6 equipped with driving devices 41 and 41a at both ends is moved in the direction of Y by the driving force of both the driving devices 41 and 41a. In the same way, another moving guide which moves in the direction of X is also installed and a moving table 7 is slidably supported by both the moving guides at their intersecting part. A location detecting device 8 detects distances l and m between the moving table 7 and the driving devices 41 and 41a. Then the detecting device 8 calculates the ratio of the distances, l/m, and adjusts the intensity of the driving force of the driving devices 41 and 41a based on the calculated result. The movement of the table 7 in X-axis is also performed in the same way. Since the driving force is controlled in such a way, the moving table 7 does not make any vibration and meandering. Therefore, the running of the moving table 7 can be stabilized.

Abstract: PURPOSE:To prevent the increase of forward voltage by using dry etching method in the final etching process. CONSTITUTION:A resist mask 9 is formed: an aperture 10 is formed by using a photo mask having an aperture in a Schottky contact electrode aperture forming region; the film 9 having the aperture 10 is used as a mask, and wet etching is performed for about 120 seconds by using hydrofluoric acid and the like; a silicon dioxide film 7 exposed in the aperture 10 is etched and eliminated by a thickness of about 1600Angstrom , thereby forming a first aperture 11 with a gentle slope on the periphery. By using the film 9 as it is, and using carbon tetrafluoride and hydrocarbon trifluoride, reactive ion etching is performed at a pressure of 3Torr for about 120 seconds; about 4000Angstrom  thickness is etched and eliminated, thereby forming a second aperture 12 reaching an N-type silicon laver 2. Thus, the aperture 12 is so formed that the shape is excellent in coverage of an electrode to be formed. Since a modified film is not formed, the forward bias can be stabilized so as to be equal to or less than 0.46V.

Inventor: MIKAMI TOMOHISA
IPC: B41J2/355
Filed: 1986-03-12
Abstract: PURPOSE:To enable recording dots to be formed with high precision regardless of the kind of recording paper by controlling so that a recording pulse voltage may be increased, thereby narrowing the width of a pulse when the smoothness of the recording paper is high, and the recording pulse voltage may be reduced, thereby increasing the width of a pulse when the smoothness is low. CONSTITUTION:When recording is started, a start signal (B) begins to be sent, and an input value through a keyboard is latched by a latching device 23 then. ROM 24 having an address for an output from the latching device 23 outputs a smoothness of recording paper corresponding to the number (C) of a designated recording paper. Further, ROM 25 having an address for the output of recording paper smoothness (E) outputs a drive pulse wave crest (F) which reduces the margin of recording density fluctuation below a prearranged value against the smoothness of recording paper. ROM 21 outputs a drive pulse width (D) for recording a density corresponding to a gradation data, (A) while PPG22 generates a pulse having a width which is equal to the output of drive pulse width. A transistor 27 is turned ON only for the existing time of the pulse, and a thermal head heating element 28 is driven by the pulse having the afore- mentioned wave crest and width.
