Title: Container for use in microwave oven
Inventor: MIZOGUCHI KYOKO
IPC: B65D53/02
Filed: 1988-11-26
Abstract: PURPOSE:To reduce pressure in a container and raise steam pressure in the container at the time of heating food with simple structure by a method wherein the inner pressure in the container is lowered to a specified level when the inner pressure is higher than a specified atmospheric pressure, and when the inner pressure is lower than the atmospheric pressure, the packing seals the container. CONSTITUTION:When steam pressure in a container main body 10 rises, the steam pressure is led through a through hole 23 to between a cover 22 of a lid 20 and pressed portion 31 of a packing 30 to be exhausted. The steam pressure in the container main body 10 is determined by the pressing force between the cover 22 and the pressed portion 31 of the packing 30 and the elastic force of the packing 30 to be a first specific pressure. That is, during normal heating, food in the container main body 10 is heated with pressure maintained at the first specific value even if the steam pressure rises. If dielectric heating is stopped, the steam pressure drops, causing the container main body 10 and the lid 20 to be applied with atmospheric pressure. This increases pressed force between the cover 22 and the pressed portion 31 of the packing 30 so that the container main body 10 and the lid 20 are in a sealed state via the packing 30.

Abstract: PURPOSE:To enable a station in need of transmission of high degree of urgency to execute urgent processing by providing the station with a privilege mode by making the station of the privilege mode capable of executing the transmission by stopping the transmission of another station forcedly even if this station is under transmission. CONSTITUTION:An optional station on an LAN to which CSMA/CD system is applied is set at the privilege mode in which transmission accessing right can be acquired preferentially, and if the transmission line of the LAN is being used in the case of the need of the transmission, the station set at the privilege mode sends a jam signal to this transmission line, and after waiting for prescribed time shorter than minimum back-off time, it starts the transmission to this transmission line. When the station in need of the transmission of the high degree of urgency is set at the privilege mode, this station (privilege station) sends the jam signal and causes collision forcedly if the transmission line is in the course of use. Thus, the station using the transmission line till now stops the transmission, and made to wait for the back-off time. On the other hand, since the privilege station starts the transmission after waiting for the time shorter than the minimum back-off time of each station, it can surely execute the transmission without causing the collision.
