  • Patent number: 6671961
    Abstract: A shaving device which comprises a shaving head (1) having at least one cutting blade (5) and two skin-supporting members (11, 13), said skin-supporting members, viewed in the shaving direction, being arranged, respectively, in front of and behind said cutting blade, and defining a contact surface (17) between the shaving head and a skin surface (53) to be treated. The cutting blade and the skin-supporting members are mounted to a sub-frame (9), which is coupled to a main frame (19) and can be displaced with respect to said main frame against a spring force (Fs). The main frame comprises two further skin-supporting members (21, 23) which, viewed in the shaving direction, are arranged, respectively, in front of and behind the sub-frame and extend substantially in said contact surface. As a result, a contact force (Fc) between the skin surface and the skin-supporting members of the sub-frame and hence a skin curvature (&ohgr;2) between the skin-supporting members of the sub-frame, i.e.

  • Patent number: 6657402
    Abstract: A low power portable device includes a terminal (2) for connection of the device to a power source. A rectifier (3) is connected to the terminal and a half-bridge circuit (4) is connected to the rectifier in order to generate an a.c. switching voltage and includes a half-bridge point (5). A control circuit (6) controls the half-bridge circuit from a power supply (7) which derives a supply voltage for the control circuit from the switching AC voltage supplied by the half-bridge circuit. The power supply comprises a charging capacitor (10) connected to the half-bridge point. A load circuit (8) is connected to the half-bridge point and the charging capacitor is connected to the half-bridge point through an impedance (13, 16).

  • Patent number: 6657388
    Abstract: The invention relates to a high-pressure discharge lamp which is provided with a discharge vessel which encloses a discharge space. The discharge vessel has a ceramic wall and is closed by a ceramic plug. An electrode which is located inside the discharge space is connected to an electric conductor by way of a leadthrough element. The leadthrough element projects through the ceramic plug with a close fit and is connected thereto in a gastight manner by way of a sealing ceramic. The leadthrough element has a first part which is formed by a cermet at the area of the gastight connection. In accordance with the invention the leadthrough element has a second part which is a metal part which extends from the cermet in the direction of the electrode.

  • Patent number: 6657361
    Abstract: The invention relates to a piezoelectric drive device with a bimodal piezoelectric resonator, with at least a first control electrode for triggering the resonator in a first drive direction, with at least a second control electrode for triggering the resonator in a second drive direction, and with a trigger circuit for supplying control signals to the first and the second control electrode. The invention is characterized in that a regulating circuit is provided for regulating the control signals, the second control electrode is designed for supplying a feedback signal to the regulating circuit when the resonator is being triggered in the first drive direction by means of the first control electrode, and the first control electrode is designed for supplying a feedback signal to the regulating circuit when the resonator is being triggered in the second drive direction by means of the second control electrode.

  • Patent number: 6655030
    Abstract: The invention relates to a shaving head (1) having at least two cutting members, the cutting edge (7)of at least one of the cutting members (5) being situated at a side, remote from the other cutting member (9), of an imaginary center plane (41) of the carrier (31) of the relevant cutting member, and having a tip angle (&agr;1)enclosed by a main side face (37) and a facet surface (43) of the carrier (31). In this manner, the cutting edge of the relevant cutting member has a tip angle (&agr;1) which is asymmetrical relative to the center plane of the carrier. As a result, a space (57), which is present between the carriers (31, 33) of the two cutting members, is divergent, viewed from the skin contact surface (29), and the risk of said space becoming clogged by cut hairs and shaving foam is considerably reduced.

  • Patent number: 6653782
    Abstract: A lamp has a base and a light-transmitting soft-glass lamp envelope sealed to the base to form a sealed lamp cavity which is filled with a non-oxidizing gas. Current supply leads are connected to the stem feedthroughs and extend into the lamp cavity. A halogen incandescent burner is located in the lamp cavity and has a light-transmitting hard-glass burner envelope which encloses a sealed burner cavity filled with an inert gas containing halogen. The burner envelope has presses at its ends. A tungsten filament coil in the burner has extended legs at its ends that extend out of the burner cavity into the lamp cavity through the burner presses and are connected to the current supply leads in the lamp cavity to act as fuses which open upon breach of the lamp envelope, thus preventing further burner operations.
