  • Patent number: 6327784
    Abstract: The invention relates to a method of manufacturing a cutting member (3). According to the method, a single side 9 of a carrier 1 of the cutting member is provided with an auxiliary layer (11). The carrier is provided with a cutting edge (7) by means of an electrochemical machining device (19), an electrode (21) of the electrochemical machining device being arranged on a side (15) of the carrier remote from the auxiliary layer. According to the invention, the auxiliary layer is provided as far as the cutting edge to be provided on the carrier, and, after the cutting edge has been provided on the carrier, the auxiliary layer is maintained on the carrier as a layer which is functional for the cutting member. In this manner, the auxiliary layer has a double function and is thus utilized in a better way. In a preferred embodiment, the auxiliary layer mainly comprises SiO2 and has a thickness below 200 nm, preferably below 100 nm.

  • Patent number: 6312584
    Abstract: An apparatus for electrochemically machining of a workpiece by means of an electrode has an actuator for setting a gap between the electrode and the workpiece. The apparatus further has a channel for flushing the gap with an electrolyte and a container for containing the electrolyte. Power cords and are provided for feeding an electric current I supplied by a power supply through the electrolyte in the gap. Near the gap an antenna is provided to pick up electromagnetic waves radiated from the gap. The antenna is connected to a band-pass filter which passes signals in a frequency band of 40 to 100 MHz to a level detector. The level detector compares the amplitude of the filtered signal with a threshold value and supplies a stop signal to the control unit when the amplitude exceeds the threshold value. The control unit is programmed to open a switch in the power supply in response to the stop signal.

  • Patent number: 6310449
    Abstract: In a device (1) having a variable-speed motor (2), a single switching device (9) has been provided for influencing the speed of the motor and for generating turn-off voltage transients (SP) on a coil terminal (3b) of the motor. The turn-off voltage transients can be applied to a voltage boosting circuit (14) for generating a d.c. control voltage required for driving a control electrode of the single switching device. This d.c. control voltage is supplied to the control electrode of the switching device with the aid of a control pulse generator (10). The d.c. control voltage reaches a higher value than the d.c. supply voltage (V) applied to the device (1). Preferably, the device includes a starting circuit (20), by which a minimum d.c. control voltage, required for the control electrode of the single switching device, can be generated for the first time in order to drive the single switching device into its conductive state.

  • Patent number: 6305083
    Abstract: A housing (1) of an apparatus has a plastics wall portion (2) provided with a plastics panel (4). To make a reliable and visually acceptable connection of the panel (4) to the wall portion (2), the panel is fixed to the wall portion by means of an induction welding process. In this way the connection is resistant to chemical compounds like lotions. Therefore a metal element (8) of electric conducting material having the shape of a closed loop wire is inserted between the wall portion (2) and the panel (4) and subsequently an electromagnetic field is applied in close proximity to the element. Preferably such panel (4) can be used to cover an opening (11) in the wall portion (2) for a display (10) and/or a switch (15) function. To make the housing watertight the element (8) between the panel (4) and the wall portion (2) should surround the opening (3,11).
