Abstract: A V-type multiple cylinder air intake is being configured to improve the volumetric efficiency by utilizing the resonance effect while also eliminating the adverse influence of the resonance effect (residual resonance) when the engine is operating in regions of medium to high rotational speeds. The V-type multiple-cylinder air intake device has two collectors with one arranged on each bank of the V-type multiple-cylinder engine; a plurality of branch pipes extending from the collectors to a respective intake port of an opposite bank; and a plurality of crossover passages extending from the collectors to a respective branch pipes extending from the collector of the opposite bank.

Abstract: A numerical control apparatus for the numerical control of a roll grinding machine comprises a flaw detecting means for scanning the entire surface of a roll (11), provided with an ultrasonic detecting head (23) for detecting flaws formed in the surface of the roll (11), a command generating means for generating cross-feed commands to repair detected flaws on the basis of flaw information about the positions and levels of the detected flaws, a control means for executing a first shaft position control operation on the basis of the cross-feed command to position the grinding wheel at a position with respect to a Z-axis corresponding to the position of the flaw by moving the wheel spindle stock in parallel to the axis of the roll and a second shaft positioning control operation to cross-feed the grinding wheel in parallel to an X-axis, and a decision means for deciding whether or not the flaw has been completely repaired and invoking the next cross-feed command if the flaw has been completely repaired.

Abstract: A work management system has input means having a function of inputting coordinate information from the surface of a panel, output means having a function of projecting electronic information onto the panel, and data processing means for executing a predetermined processing, e.g., preparation and input processing of a form, a chart or a drawing, retrieval, editing, totalization, etc., by establishing a correspondence between the information projected on the panel by using the output means and the coordinate information input from the input means. The data processing means displays a list of registered items to be designated in a window for selection of one of the items, whereas, when coordinate information is input from two points for an entry column for time setting, the data processing means draws a bar between the two points. Control information which is conformable to working hours of equipment at a work site, e.g.

Abstract: A numerically controlled machine tool machines a workpiece into a roll while rotating the workpiece at a prescribed speed, moving the tool back and forth radially thereof, and moving the tool axially thereof. The misalignment of the workpiece with the axis of the machine tool can be corrected by measuring the amount of misalignment of the axis of the workpiece and entering the measured amount as corrective data into a control system which stores numerical control data produced by successively programming amounts of radial movement of a tool dependent on axial positions of the tool; calculating corrected values of, among said numerical control data, the positional data of the tool in the axial direction and/or corrected values of the data on the amounts of movement of the tool in the radial direction, based on the corrective data; and controlling said tool based on the calculated corrected values to machine the workpiece.

Abstract: The present invention concerns an overheat protection device for a catalytic converter in which the injection of secondary air is prevented when the temperature in the catalytic converter is higher than a lower predetermined value and a warning signal is produced when the temperature is higher than a higher predetermined value.
