Title: Petroleum combustion device
Inventor: KAWASAKI YOSHITAKA
IPC: F23D3/02
Filed: 1985-02-12
Abstract: PURPOSE:To enable to perform complete quenching as well as to prevent generation of a bad odor or CO etc. after quenching, by a method wherein shutting plate which is advance and retreat free is inserted between a combustion chamber and a fire plate, and two openings, of which one opening which line up with a combustion chamber passage and one opening which makes air convect and pass, are provided. CONSTITUTION:While combustion, fuel which is evaporated by self-heating from a wick which is raised through a combustion opening 8a of the shutting plate 8 receives the supply of air from air holes 6a in the combustion chamber 6, and burns mixingly. In other way, while quenching, the wick is lowered by an operating knob 3 and is made to immerse under the fire plate 5 as well as the shutter plate 8 is pushed in and fire is quenched. When the shutter plate 8 is pushed in while quenching, the attachment of fuel on the surface of the shutter plate 8 is removed and the generation and transpire of bad odor materials such as a sort of aldehyde or CO by the partial oxidation of fuel can be avoided without rising fuel vapor in the high temperature combustion chamber 6.

Title: Discharge tube lighting circuit and discharge tube lighting method
Inventor: MATSUMOTO NORIO
IPC: H02M7/48
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent noise generation caused by piezoelectric transformer vibrations due to the light modulation of a discharge tube by providing a means for alternately supplying an alternating current having different amplitudes on a piezoelectric transformer driving circuit for a piezoelectric transformer in time-sharing. SOLUTION: A modulated light generator 22 outputs a triangular wave having a repeatable frequency of power time-sharing. A modulated light signal generator 24 compares this triangular wave with the voltage of an external modulated light signal 23 and generates a rectangular wave. The rectangular wave outputted from the modulated light signal generator 24 switches a transistor Tr on and off and divides a reference voltage V1 into two values by resistance to be changed. When the rectangular wave is high, the transistor Tr is on and the partial pressure ratio of the reference voltage V1 becomes low. When the rectangular wave is low, the transistor Tr is off and the partial pressure ratio of the reference voltage V1 becomes high. The duty ratio of the rectangular wave pulse depends on the magnitude of an external modulated light voltage and can be sequentially altered.

Abstract: PURPOSE:To produce header in a large quantity, by laminating second ceramic- printed layer through a metallized layer onto a ceramic-printed layer provided on surface of a ceramic plate. CONSTITUTION:First ceramic 3 is printed on a green shet 1, and then, metallized printing is executed, and second ceramic 3' is further printed.
