Title: Gas babble brick for metallurgical vessel
Inventor: HANSU HEEFUGEN
IPC: C21C7/072
Filed: 1984-11-14
Abstract: A gas bubble brick for metallurgical vessels consists of a porous, gas-permeable shaped brick (2) made of refractory material, a gas-tight partial encasing surrounding the latter, which encasing is welded together from a metal jacket (4) extending around the lateral circumferential area of the shaped brick and a metal cover (6) covering the outer face of the shaped brick, a gas supply pipe (10) which is welded to the rim of a central gas inlet orifice (8) of the metal cover (6), as well as a break-through safeguard in the area of the gas supply pipe. In order to prevent closure of the gas bubble brick in the gas outlet area and in order thereby to ensure purge readiness, a constricted cross-section (12) is provided inside the gas supply pipe (10) at a distance from the gas inlet orifice (8) of the metal cover (6), there being provided in the pipe section between the metal cover and the constricted cross-section a closure body (17), which is movable at least in the axial direction of the gas supply pipe and is, for example, a copper ball or the like, the cross-section of which is smaller than the inside diameter of the gas supply pipe (10) and greater than the constricted cross-section (12). The closure body (17), together with the constricted cross-section (12), thereby forms a non-return valve, which prevents a pressure drop occurring in the gas bubble brick after switching off the gas supply.

Title: Pen positioning method for ink jet printing head carriage provided with a plurality of pens
Inventor: DEIBUITSUDO DABURIYU PINKAANER
IPC: B41J2/21
Filed: 1993-09-27
Abstract: PURPOSE: To semi-automatically compensate in a user interaction for an aligning error between a monochromatic pen and a trichromatic pen replaceable in an ink jet print head carriage. CONSTITUTION: The method for aligning a pen of an ink jet print head carriage comprises a user interaction with automatic pen alignment firmware to select the best alignment among a number of illustratively printed options to achieve semi-automatic inter-pen alignment. Its algorithm is invoked by keystroke on a keypad of the ink-jet printer's control panel, typically when a new pen is installed in the printer's carriage. The printer prints stored horizontal and vertical alignment test patterns, including superposed patterns of spaced linear segments, that illustrates a range of alignment options indicated by printed symbolic indicia. The printer also prints a stored illustration of the printer's keypad keys that should be struck to make selected alignments. The user examines the printout, selects desired alignments and strikes selected ones of the indicated keys.  Horizontal alignments are made in firmware by shifting the timing between ink-jet firings. Vertical alignments are made in firmware by pixel shifting, i.e., by selecting different ink-jets for firing.

Title: Ignition timing controller for internal combustion engine
Inventor: SHINSHI MAMORU
IPC: F02P5/153
Filed: 1987-09-25
Abstract: PURPOSE:To secure a fail-safe function as well as to aim at improvement in reliability by judging that there is something wrong with a cylinder internal pressure sensor at a time when an increment in cylinder internal pressure prior to a compressive top dead point of an internal combustion engine is smaller than the threshold value corresponding to this increment. CONSTITUTION:A sensor 2 detects cylinder internal pressure in an internal combustion engine, and a means 3 detects a maximum crank angle position in this cylinder internal pressure. A means 6 compensates fundamental ignition timing on the basis of a feedback compensation value, and calculates output ignition timing. In these means, an increment in cylinder internal pressure ranging from the specified crank angle position to a compressive top dead point is integrated by a device 7. When the integrated value by this means 7 is smaller than the threshold value corresponding to this integrated value, it is judged that there is something wrong with the sensor 2 by a means 8.
