Title: Level conversion circuit
Inventor: UMEZAWA YOSHIAKI
IPC: H03K19/0175
Filed: 1990-06-29
Abstract: PURPOSE:To reduce the power consumption and to simplify the circuit constitution by forming the level conversion circuit of a current switch having a MOS transistor (TR), a bipolar TR and a constant current source and with a constant voltage circuit applying a constant voltage to the current switch. CONSTITUTION:When an L level input signal SI is fed to an input terminal 41, the gate of a PMOS 43 goes to an L level and the PMOS 43 is turned on. In such a case, since the potential of a drain side node N1 of the PMOS 43 gets higher than that when the PMOS 43 is turned off by a ground potential VSS, the emitter potential of an NPN TR 45 rises and the NPN TR 45 is turned off. Thus, the drain current flowing through the PMOS 43 from the ground potential VSS flows to a negative power supply potential VEE via a constant current source 46. In such a case, an output signal SO goes to an H level.

Filed: 1982-09-30
Abstract: PURPOSE:To enable to obtain stable combustion of fuel promptly after ignition, by disposing a porous sleeve to extend from the central part of a center hole of a combustion ring toward a distributor plate. CONSTITUTION:A porous sleeve 5 is disposed to extend from the centrals part of a center hole of a combustion ring 3 toward a distributor plate 2. The porous sleeve 5 heated by an ignition heater 4 produces upward flow of air near the surface thereof and guides ignited combustion flame toward the central part of a pot by the draft produced by the porous sleeve 5. Therefore, even if the draft of air inside a heat-resisting glass sleeve 12 defining a combustion chamber is weak because so much time is not passed after ignition, it is prevented that the combustion flame flows irregularly. Further, if the porous sleeve 5 is disposed such that proper clearance is formed between the top of the porous sleeve 5 and the distributor plate 2 and a guide plate 6 is disposed above the porous sleeve 5, upward flow of combustion flame and combustible gas guided by the porous sleeve 5 is carried to the circumferential part of the distributor plate 2 smoothly and uniformly by the function of the guide plate 6. Thus, it is enabled to burn fuel in a stable manner promptly after ignition of fuel.
