Title: Combustion chamber structure of engine
Inventor: FUJII NORIAKI
IPC: F02F1/24
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal ignition and fire propagation inhibition from occurring by avoiding the formation of ridge lines in the circumference of an ignition plug and providing a connecting face connecting respective conical faces to each other in a cylinder head. SOLUTION: A ceiling wall face of a combustion chamber is formed of a closed end of a recess 21. A part of the recess 21 is constituted of a pair of air intake side conical faces 22 continuing to the both intake valves 10, a pair of exhaust side conical faces 23 continuing to the both exhaust valves 13, and flat squish area forming faces 24, 25. In the circumference of the ignition plug 18 arranged in an approximately central part of the combustion chamber, first- fifth connecting faces 28, 29, 30, 31, 32 are formed in the ceiling wall face of the combustion chamber, namely, the recess 21 in such a state as cutting ridge lines formed by crossing respective conical faces 22, 22, 23, 23 with each other. An acute angle part is thus eliminated from formed in the ceiling wall face of the combustion chamber.  This constitution enables the prevention of abnormal ignition by a heat spot or of the fire propagation inhibition from the ignition plug.

Title: Method for vacuum-refining molten steel
Inventor: HIGUCHI YOSHIHIKO
IPC: C21C7/10
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To improve degassing speed and to remarkably shorten treating time of molten steel without bringing about increases of an equipment cost and the running cost by controlling a parameter calculated from circulating speed, cross-sectional area in a vacuum vessel and bath depth in the vacuum vessel in a specified range. SOLUTION: Molten steel after blowing in a converter, in tapped into a ladle and the ladle is transferred to an RH to execute degassing treatment. At this time, the parameter X is controlled to in the range of 0.3-1.0. Then, the parameter X=Q/(H.A1/2) and wherein, Q: the circulating speed (m3/s), A: cross-sectional area (m2) in the vacuum vessel, H: the bath depth (m) in the vacuum vessel. Concretely, the control of the parameter X is suitably adjusted to The circulating speed Q and the bath depth H in the vacuum vessel, because the cross-sectional area A in the vacuum vessel is constant. In this way, the RH treating time can be shortened by >=25% and this cost is reduced to a half and also, matching of a production pitch with a continuous casting method can be obtd. in good condition.

Title: Method for controlling output of welding power source in short circuit transfer arc welding method
Inventor: OGASAWARA TAKAAKI
IPC: B23K9/073
Filed: 1983-12-20
Abstract: PURPOSE:To decrease generation of spatters and to obtain good weldability by controlling optionally the ratio between the high current period when high current is conducted from right after generation of an arc in short circuit transfer arc welding and the low current period when a short-circuit arises in succession thereto. CONSTITUTION:The ratio TAB/TAP between a low current period TAB and a high current period TAP is set and the specified ratio TAB/TAP is maintained by increasing or decreasing the period TAP, a low current value IAB, a wire feed speed and a high current value IAP or high voltage value VAP according to the error between the set ratio and the detected actual ratio. If, therefore, the actual ratio increases as compared to the set ratio TABT/AP and the number of short- circuits decreases, the burning up rate of the wire is decreased by decreasing the period TAP, the value IAB and the value IAP or the value VAP according to the rate of the error and further the number of short-circuits is increased by increasing the wire feed speed. Conversely when the actual ratio decreases, the period TAP, the value IAB and the value TAP or the value VAP are increased and further the wire feed speed is decreased to decrease the number of short-circuits.

Abstract: PURPOSE:To reduce man-hour in the case of focusing by a manual operation and to enhance reading accuracy by processing the read signal of the pattern of an original for adjustment so that resolution may be obtained and adjusting a distance between a read means and an optical lens. CONSTITUTION:The read means 8 is attachably/detachably connected to a read device 2, and the read signal of the pattern 10 read by the read means 8 from the original for adjustment 1 is processed by a signal processing means 9 so as to obtain the resolution, then a decision means 11 decides whether the resolution is equal to or above a reference value, or under the reference value. In the case of deciding that the resolution is equal to or above the reference value based on the decided result by the means 11, it is judged that focusing is attained. In the case that the resolution is under the reference value, at least either of the optical lens 7 and the read means 8 is moved by a moving means 12 by a 1st specified distance which is previously set. Then, it is repetitively moved by the means 12 by the 1st specified distance until the decided result attains equal to or above the reference value so as to perform focusing. Thus, focusing is automatically performed, an error in adjustment is eliminated and the reading accuracy is enhanced.

IPC: B24D3/00
Filed: 1991-09-20
Abstract: PURPOSE:To perform the machining of extra-abrasive grains for an electrodeposited grinding wheel stably and positively with high accuracy. CONSTITUTION:Diamond abrasive grains 11 are placed in a row on a flat plate 12 formed of high-accuracy machined heat resistant ceramics or the like. A high-accuracy machined iron plate 13 of high temperature (about 600 deg.C) is pressed parallel to the flat plate 12 by adding pressure P gradually, and the iron component is mechanically stuck to the pressing face to form an iron stuck layer. At the time of applying electroless plating to form an electrodeposited grinding wheel, plating proceeds with the iron stuck layer as a core, and a conductive thin film is formed on the plane. Since this thin film is formed with an iron compound as the core, the iron component displays anchor effect so as to improve adhesion and prevent flaking.
