Publication number: 20090283599Abstract: A method accurately inspects whether an IC inlet to be inspected is non-defective or defective in a state in which a large number of IC inlets are formed over an insulating film. The inspection of IC inlets formed over an insulating film is performed by transmitting microwaves to the IC inlets from antennas. To selectively irradiate the microwaves to only one IC inlet to be inspected out of a large number of IC inlets that are formed over the insulating film, a radio-wave absorbing plate is inserted between the insulating film and the antennas, and the microwaves are irradiated to the IC inlet through a slit formed in the radio-wave absorbing plate. The radio-wave absorbing plate is configured such that the slit, which is substantially equal to the IC inlet in size, is formed in a portion of a planar plate that is formed of a radio-wave absorber.Type: ApplicationFiled: July 30, 2009Publication date: November 19, 2009Inventors: Michio OKAMOTO, Hisao Yamagata, Nobuo Murakami, Keizo Kakitani, Hidehiro Fujiwara, Takeshi Saitou

Patent number: 7027751Abstract: An electrophotographic image forming apparatus of the present invention includes a photoconductive drum provided with a photoconductive layer on its surface. A charger uniformly charges the surface of the drum while an exposing unit exposes the charged surface of the drum to thereby form a latent image on the drum. A developing device develops the latent image with toner by feeding the toner to the drum to thereby produce a corresponding toner image and collects residual toner left on the drum after image transfer. An image transferring device transfer the toner image from the drum to an intermediate image transfer body. An air conditioning unit sends dehumidified, air-controlled air to a space around said photoconductive element.Type: GrantFiled: July 3, 2003Date of Patent: April 11, 2006Assignee: Ricoh Company, Ltd.Inventors: Tetsuroh Miura, Katsuaki Miyawaki, Takeshi Saitou, Takeo Suda, Yasushi Nakazato, Yasuo Suzuki
