Title: Heat insulating device for bath burner
Inventor: IKENAGA MITSUO
IPC: F24H1/00
Filed: 1991-04-15
Abstract: PURPOSE:To suppress waste consumption of energy during heat insulation continuous operation by a method wherein a plurality of heat insulation control means are selectively operated by a switching means, and a heat insulation temperature when a heat insulation time is set to a high value is set to a value lower than that when it is set to a short time. CONSTITUTION:First and second heat insulation control means 21 and 22 are selectively operated by means of a switching means 3. The switching means 3 is constituted such that automatic switching operation is effected depending upon whether or not a heat insulation time is set to a high value. Namely, an output from a heat insulation time setter 41 is compared with an output from a reference time setter 42 to decide a maximum value of a heat insulation time in which the first heat insulation control means 21 is brought into an operation state by means of a comparator 40. An output from the comparator 40 is inputted to a switching means 3. As a result, when a heat insulation time is for example, below a reference time, the comparator 40 is brought into a non-output state, and the first heat insulation control means 21 is operated by means of the switching mesas 3. This constitution holds a heat insulation temperature when a heat insulation time is short to a relatively high value.

Abstract: PROBLEM TO BE SOLVED: To provide a non-volatile storage with excellent storage characteristics and high reliability, and capable of microfabrication. SOLUTION: The storage device comprises a laminated structure formed of an interface control insulating film 2, a ferroelectric thin film 3 and an upper electrode ascendingly formed on a Si single crystal substrate 1 in a gate electrode portion of a transistor. In this case, the interface control insulating film 2 is formed of a laminated film of silicon oxide and silicon nitride or an insulating film mixed with these components, and a carrier injection stopper layer 4 is formed in the interface between the ferroelectric thin film 3 and the upper electrode.  Thereby, the silicon nitride film acts as an etching stopper in etching for forming the gate, while the carrier injection stopper layer 4 and the interface control film 2 prevent the carrier from being injected from the substrate 1 and the upper electrode to the ferroelectric thin film 3, thus a MFIS-FET is obtained which is capable of microfabrication by self-aligning and has excellent storage characteristics and high reliablility.

Abstract: PROBLEM TO BE SOLVED: To prevent carrier attraction with simple constitution at low cost in the case of disconnecting a power source for generating developing bias voltage when the bias voltage is impressed on a developing means by providing a discharging light source which is lit to optically discharge surface potential on an image carrier in the case of disconnecting the power source voltage. SOLUTION: When the power source voltage Vcc from a power source circuit 65 becomes equal to or under a specified voltage, a power source disconnection detection circuit detects the disconnection of the power source and turns on an NPN type transistor in a discharging light source lighting circuit. As a result, charge voltage by a charge circuit is impressed through the discharging light source 33 and the transistor provided between an electrifying device 15 and a developing device 17, so that a current flows to the light source 33, which is lit. In the case of disconnecting the power source of a device main body in the midst of image forming operation, the surface potential on a photoreceptor drum 14 is discharged by the light source 33, which is lit, until the drum 14 naturally stops and the surface potential naturally disappears even in the case the drum 14 is slightly rotated.
