Title: Image forming method
Inventor: MENJO TAKESHI
IPC: H04N1/00
Filed: 1993-12-22
Abstract: PURPOSE:To shorten work time by consecutively forming images plotted on the front and back surfaces of an original on plural transfer materials on a transfer material carrier. CONSTITUTION:A double-sided original placed in a tray 204 is carried so that its front surface may be on a platen side first. On an image forming device side, two transfer materials Pa and Pb are consecutively carried and arranged at a specified position. Firstly, the magenta image on the front surface side of the original is transferred to the transfer material Pa. Next, the original is reversed so that the image on the back surface may be on the platen side, and the magenta image on the back surface of the original is transferred to the transfer material Pb. After successively forming cyan, yellow and black images on the respective transfer materials Pa and Pb in the same manner, the transfer materials Pa and Pb are consecutively separated from the transfer material carrier. The images are simultaneously formed by such image forming operation in a state where the two transfer materials Pa and Pb are sucked to the transfer material carrier. Thus, copying is performed at speed twice as high as the case in the conventional method.

Title: Electrostatic chuck
Inventor: SAEKI HIROAKI
IPC: B23Q3/15
Filed: 1992-12-08
Abstract: PURPOSE:To provide an electrostatic chuck, which can obtain the strong attraction force with a low voltage and does not generate residual attract force. CONSTITUTION:A resistor layer 3 comprising a semiconductor is arranged on the wafer mounting surface of a suscepter 2. A small gap is present at the contact plane between the resistor layer and a semiconductor wafer W. When a voltage is applied from a DC power supply 36 into a counter electrode 32, which is provided at the lower surface of the resistor layer 3, the potential difference is generated between the lower surface of the semiconductor wafer W and the upper surface of the resistor layer 3. Static electricity power is generated by the potential difference, i.e., the contact potential difference. The semiconductor wafer W is attracted with the resistor layer 3 by the static electricity power. The electric charge of OH<-> generated by the ionization of moisture, which is considered to be the cause of residual sucking force, flows to the ground through the resistor layer 3. Therefore, the occurrence of the residual attracting force is suppressed.
