Title: Heating cooker
Inventor: SUGIHARA MICHIMASA
IPC: H05B6/12
Filed: 1990-02-16
Abstract: PURPOSE:To obtain a heating cooker with remarkably reduced noise in standard frequency zone by arranging a circular metal film on a cooker body at a position opposing to a heating coil, so that magnetic flux leaking from the cooker body is decreased. CONSTITUTION:If high frequency current is supplied from an inverter circuit 13 to heating coils 6 and 7, the coils 6 and 7 generate magnetic flux. The magnetic flux causes induced current in a container 2, which in turn generates heat and starts cooking. At this time, current is induced by the magnetic flux of the heating coils 6 and 7 in a circular metal film 10 arranged on an outer periphery opposing to the heating coils 6 and 7, and counter magnetic flux to the magnetic flux of the coils 6 and 7 is formed in the film 10. These magnetic fluxes oriented counterwise to each other act to cancel mutually. Thus leakage of magnetic flux from the cooker body 1 can be reduced.

Filed: 1980-03-21
Abstract: PURPOSE:To generate an N-bit parallel code, which corresponds to one of 2N input terminals, at a low cost with simple constitution by making the logical state of the input terminal different from those of the other input terminals. CONSTITUTION:To select a code to be generated, data selector DS1 has 2N (n=3 in this case) input terminals 10-17, and output terminal 5 is connected to switch circuit 4.
