An image forming method by the electrophotographic process is disclosed. The image forming method comprises the steps of forming a plurality of toner images different in color on an image carrying member by repeating the developing of the electrostatic latent image on the image carrying member with developers containing both toner and carrier, and transferring said plurality of the toner images at a time onto a receiving material, in which the toner to be provided for at least the initial toner image formation is mixed with 0.2 to 2% by weight of metal oxide particles having a BET specific surface area determined by nitrogen adsorption of from 30 m.sup.2 /g to 60 m.sup.2 /g. The method provides clear multicolor images free from any deterioration in the resolution due to transfer doubling trouble as well as in the image quality due to transfer-off spots.
摘要:
A circuit interrupter comprising a pair of separable contacts at least one of which is movable, and an operating mechanism operatively connected to the movable contacts for opening and closing the contacts. The operating mechanism includes a movable contact arm having mounted thereon the movable contact, a latch lever pivotally mounted on the movable contact arm, and a toggle link mechanism connected at its one end to an operating handle and the other end of which is directly engageable with said movable contact arm and the latch lever. The movable contact arm has a latch surface, and the latch lever has a latching end which, in cooperation with the latch surface, releasably catches the other end of the toggle link mechanism. The operating mechanism further comprises a yieldable member providing a yieldable stop surface for preventing the automatic return movement of the other end of the toggle link mechanism from an extended position after the trip operation to a reset position and for yieldably maintaining the other end of the toggle link mechanism at a position in which the toggle link mechanism is partly collapsed. The yieldable stop surface can be overcome by the manual moving effort on the operating handle.

A battery module is provided in which a gap at a bonding section between a positive electrode bus bar and a negative electrode bus bar is less likely to be formed in a bonding process, and stress-induced strain is less likely to be caused at the bonding section after the positive electrode bus bar is bonded to the negative electrode bus bar. The battery module includes a plurality of cells 100 arranged with a same polarity oriented in a same direction, a positive electrode bus bar 200 by which positive electrode terminals of the cells 100 are electrically connected to each other in parallel, and a negative electrode bus bar 300 by which negative electrode terminals are electrically connected to each other in parallel. The positive electrode bus bar 200 includes a flat plate-like extended portion 210 which extends from an edge of the positive electrode bus bar 200 toward the negative electrode terminals, and the negative electrode bus bar 300 includes a bent portion 320 which is bent from an edge opposite to the extended portion 210 toward the negative electrode terminal. In the extended portion 220, a slit 230 is formed at an edge in a width direction perpendicular to an extension direction of the extended portion 220.
