Inventor: HARA KENJI
IPC: G06F17/40
Filed: 1985-02-08
Abstract: PURPOSE:To detect quickly a variation of a data by comparing new and old data by a harware, comparing its difference, generating an interruption if a variation occurs, and requesting a transfer suspension to a CPU. CONSTITUTION:When reading out a memory 1 by a CPU, a memory selecting signal inversion MS and a reading-out signal inversion RD become L, a bus buffer 4 makes a signal pass through to the right from the left, and the contents of the memory 1 are sent out onto data buses D0-D3. When executing write to the memory 1, a data sending-out signal DT/inversion R becomes H, and a signal ALE appaering in the beginning of a machine cycle becomes H. Therefore, an output signal SA of an AND gate 7 becomes H, and an output signal Qa of D-flip-flop 5a becomes H only at 1 clock time. In this way, the bus buffer 4 cuts the connection of the memory 1 and the data buses D0-D3. Also, read-out is requested to an inversion RD terminal of the memory 1 by an inversion output signal Qa of a D inversion flip-flop 5a.

IPC: A47J27/00
Filed: 1995-02-09
Abstract: PURPOSE: To considerably get rid of the lack of heating on the side surface of a pot without reducing the content volume of the pan so much in comparison with the entire dimension of the pan. CONSTITUTION: The side surface shape of a pan 8 is formed in the shape of a curved surface so that an inclination angle α on the downside 8a of the outer side surface can be larger than an inclination angle β on the upside 8b of the outer side surface with a water level height A of maximum cooked rice quantity as a border. The inner side surface of an inner frame 4 confronted to the downside 8a of the outer side surface of the pan 8 is formed into a slope whose inclination is smaller than that of the inclined curved surface on the downside 8a of the outer side surface of the pan 8. At the position of an almost 2/3 height B as high as the water level height A of maximum cooked rice quantity, a gap (a) between the pot 8 and the inner frame 4 is set from 2mm to 6mm.  Therefore, the enough gap for radiation heat supply can be secured between the side surface part downside of the pot 8 required for cooking rice and the inner side surface of the inner frame. Since the downside of the side surface part of the pan 8 is formed in the shape of curved surface protruded outside, it is not necessary to reduce the content volume of the pan 8.
