A method and a device for cutting gas concrete employing cutting wires (35), whereby, in order to decrease shocks and vibrations, and in order to cut blocks of gas concrete more rapidly and with a finer surface structure, said wires (35) are guided and driven separately from one another in such a way that they are guided in their lengthwise direction relative to a cutting frame (14) and that they ...

PURPOSE:To suppress the abrasion of a flocked belt while preventing the failure in the start of the removing of residual roving, by switching a driving power applied to a mobile frame in the forward driving of a flocked belt in such a manner as to be smaller in the final stage of the stroke than in the initial stage. CONSTITUTION:A flocked belt 12 is placed on a mobile frame 20 and a switching poi...

In an apparatus for controlling a vehicle clutch which is located between an internal combustion engine and a transmission device whose gear shift position is determined in accordance with the operating position selected by a selector, the apparatus comprises a control signal generator which determines the operating pattern for engaging the clutch in response to at least a position signal showing ...

PURPOSE:To prevent an engine from being raced, by determining the opening degree of a fuel supply means in accordance with the clutch engaged amount detected by a clutch engaged amount detecting means and the accelerator depressed amount detected by a accelerator depressed amount detecting means. CONSTITUTION:In an automobile provided with an automatic clutch, when an accelerator pedal 11 is depre...

PURPOSE:To execute satisfactory welding without weld defects such as blowholes by providing projections of a suitable height to the lap parts of materials to be joined to form an adequate spacing and escaping a gasified coating material through this spacing in the stage of welding. CONSTITUTION:Galvanized steel sheets 1, 2 having sheet thicknesses t1, t2 are fixed and held by means of clamper 14 a...

PURPOSE:To enable a transmitting quantity of torque from an engine at the time of speed change to be varied and prevent excessive load from being applied to a frictionally engaging device by controlling the quantity of torque of said engine when manually shifted up with power on. CONSTITUTION:The outputs of an intake-air temp. sensor 100, a throttle sensor 102, a water temp. sensor 104, an O2 sens...

PURPOSE:To improve a shift feeling at the time of a transition period, by altering a variable speed point of a shift map to somewhat lowish when a condition, regulating an engine torque change, is materialized, while depaying the alteration of the variable speed point till the next speed change occurs. CONSTITUTION:A controller bearing the above caption is selecting shift steps of an automatic tra...
