Abstract: The tool comprises a base plate (3) having openings (5), from the lower face (24) of which are fixed punches (4,4a). The openings are located along two orthogonal axes, one of which is inclined relative to one of the tool base plate edges at an angle between fifteen and twenty degrees. The tool works with a lower tool separating the cut-out sheets (2). The punches deform under the pressure engendered by downward displacement of the upper tool and meet a solid separation bar (9). One of the lateral faces of the punch section is tangent to one of the openings so that the pitch between the punches provides an identical total pressure from them, on the cut-out to be separated, near one lower tool separation bar, whatever the position occupied by the separation bars. The non-separated sheet has a front nipped piece (22) gripped by pincers (23) which transport this sheet to the cut-out separation and reception station. <IMAGE>

Abstract: PROBLEM TO BE SOLVED: To prevent reverse rotation or stall of a prime mover by sensing the revolving speed of the prime mover. SOLUTION: The revolving speed of an engine 50 is determined by calculation from the relative rotating angle of an inner rotor 34 with an outer rotor 32 sensed by a resolver 39 mounted on a clutch motor 30 and the rotating angle of a rotor 42 sensed by a resolver 48 furnished on an assist motor 40. Because the rotating angles are obtained by the resolvers as values equipped with positive and negative signs, the revolving speed of the engine 50 will be determined as a value equipped with a positive or negative sign. When the obtained revolving speed of engine 50 becomes a negative value or exceeds downward the specified level, the torque of the clutch motor 30 is controlled by a control device 80 so that the engine 50 rotates at a speed over the specified level. As a result, reverse rotation or stall of the engine 50 can be prevented.

Abstract: Provision of an abnormality detection and suppression system for a valve apparatus, which is capable of detecting abnormal states such as leakage through valve seats or a gland/packing assembly and coping with the abnormality while ensuring protection for the valve apparatus by controlling a driving unit for a valve stem on the basis of information as detected, by means of a vibration sensor, a temperature sensor and a strain sensor are disposed internally of a valve stem 4 at a portion thereof which lies outside of a valve casing of the valve apparatus. When vibration of the valve stem brought abut by leakage through valve seats is detected by the vibration sensor in a fully closed state of the valve apparatus, a valve body thereof is driven further in the valve closing direction by a driving unit 13 controlled by a control unit, both being disposed externally of the valve casing, until the leakage and thus the vibrations disappear while monitoring simultaneously a load applied to the stem by the strain sensor. On the other hand, when a temperature change of the stem is detected by the temperature sensor in the fully open state of the valve apparatus, the control unit decides that the temperature change is due to leakage through a gland/packing assembly 12 of the valve apparatus to thereby control the driving unit so that the stem is driven to move the valve body in the valve opening direction while monitoring simultaneously a load applied to the stem until the change in the temperature is canceled out.
