Patent number: 10697643Abstract: In a cooker according to the present disclosure, a convection heater for executing a convection mode and a circulation fan are disposed in a convection forming space that is in communication with a heating chamber, and a fan driver is disposed outside of the convection forming space. The cooker includes a leakage suppression mechanism for suppressing a microwave leak from the convection forming space. The leakage suppression mechanism is formed by a coaxial seal for setting a distance between opposing faces, i.e., between a circulation fan shaft passing through a first wall forming the convection forming space and the first wall to a predetermined distance or smaller. Therefore, a microwave leak from a mechanism for executing the convection mode is suppressed, and heat cooking with a microwave-heating mode can highly effectively be performed.Type: GrantFiled: August 23, 2016Date of Patent: June 30, 2020Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Seiichi Yamashita, Takahiro Hayashi

Patent number: 7609164Abstract: A radio tag evaluation system includes a transmission member providing a frequency signal to a radio tag. A transmitting antenna, which is placed on one side of the radio tag for transmiting the inquiry signal supplied from the transmission member. The radio tag is placed and supported around the center of an anechoic box. A receiving antenna is placed on the other side of the radio tag. A reception member is connected to the receiving antenna for analyzing a response signal. The transmitting antenna and the receiving antenna are placed orthogonally to each other, and the primary face of the radio tag is placed substantially at an angle of 45 degrees with respect to the transmitting antenna. The receiving antenna is unable to directly receive a transmission radio wave which has passed around the radio tag. Accordingly, a response signal emitted from the radio tag can be relatively strongly received.Type: GrantFiled: August 23, 2006Date of Patent: October 27, 2009Assignee: Honda Motor Co., Ltd.Inventor: Seiichi Yamashita
