    摘要: A method and apparatus are provided for manufacturing an element (1) of a magnetic chuck comprising pole parts (2) of soft magnetizable material and parts (3) of a nonmagnetizable material connected thereto. The method implies that the parts (3) of the non-magnetizable material are casted on to the pole parts (2) of soft magnetizable material. In case of the manufacture of a permanent magnetic chuck cavities (18) are saved between the pole parts (2) during casting. For this purpose the apparatus comprises a mould (10) having ribs (20) therein for forming said cavities (8), the ribs (20) also acting as spacer means for holding the pole parts (2) in a spaced apart relationship during casting. The resulting element (1) of a magnetic chuck has a strong and rigid structure and is less costly to produce than the prior art chucks.

    摘要: A machine unit (18-1) provided with an electrostatic retention means (2) is disposed at a desired position. The electrostatic retention means (2) includes a pair of electrodes (4, 6), an attraction member (8) associated with the pair of electrodes (4, 6) and in which static electricity is induced so as to generate an electrostatic attraction force which attracts and retains an object (12-1), and a power source circuit (10) for supplying positive and negative charges to the pair of electrodes (4, 6) while sequentially and alternately changing the polarity thereof.

    摘要: Un appareil de commutation (1) pour changer la polarite ou l'intensite du champ magnetique de corps ferromagnetiques, p.ex. celui de tendeurs a aimant permanent, presente un arrangement en serie. Cet arrangement contient au moins un enroulement (3) apte a recevoir des corps ferromagnetiques (6), un commutateur electronique commandable ainsi qu'un dispositif d'accumulation d'energie (10). Afin de creer un appareil de commutation de petite dimension, a circuit electrique simple et a commutation fiable, on choisit comme commutateur electronique une lampe eclair (2).
