Title: Combustion safety device
Inventor: OOHASHI NORIYOSHI
IPC: F23N5/00
Filed: 1978-12-29
Abstract: PURPOSE:To detect whether burning flame is normal or abnormal and secure the safety of its combustion by closing a solenoid safety valve at its abnormal time by bringing the burning flame into contact with one electrode surface of a combustion sensor to thereby heat the electrode and bringing the combustion exhaust gas into contact with the other electrode surface thereof. CONSTITUTION:In case that a knob 17a of a push and turn type plug 17 is depressed when using a gas equipment, a solenoid safety valve 18 is opened. When the knob 17a is then turned, the plug 17 is opened to this ignite an ignition plug 22. Thus, an ignition flame burner 20 is ignited to thereby form an ignition flame F. Then, a main burner 15 is ignited to thereby form a main combustion flame F'. The ignition flame F heats the electrode surface 14 on the outer periphery of a combustion sensor 11 at this time. When exhaust gas P2 from the combustion flame F' passes through the inner hole of the sensor 11, the gas P2 makes contact with the electrode surface 13 on the inner periphery of the sensor 11. The electromotive force of the sensor 11 at this time continuously open the solenoid safety valve 18 continuously opened upon discharge of a capacitor 24 at its initial ignition time.

Title: Heat pipe
Inventor: MUNEKAWA MASAAKI
IPC: F28D15/00
Filed: 1978-12-29
Abstract: PURPOSE: To simplify wick structure of heat pipe and to enable to disposed the heat pipe horizontally, by shaping the heat pipe in a loop shape.  
     CONSTITUTION: Work fluid W staying in lower straight-pipe portion 1b is evaporated by heat transferred from heat source through heat transmitting means 6 and flows upward into upper straight-pipe portion 1a via opposite curved pipe portions. In the upper straight-pipe portion 1a, gasified work fluid releases heat and is condensed into liquid, and work fluid thus liquiefied flows downward into heating straight-pipe portion 1b along the inner surface of heat pipe 1. Through the operation of heat pipe 1 described above, it is enabled to release heat. Therefore, in case of applying such a heat pipe in an apparatus such as radiator, heat recovering apparatus or the like, it is enabled to operate heat pipe efficiently by forming a loop-shaped heat pipe including a pair of straight-pipe portions and locating these straight-pipe portions horizontally and at positions displaced vertically from each other.

Title: Liquid tube convection type combustion heating furnace
Inventor: KUBOTA NORIKAZU
IPC: F22B31/00
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To surely ignite a planar flame type burner by connecting a liquid tube of at least one corner on the side of the planar flame type burner to an adjacent furnace wall by a connection plate. SOLUTION: A liquid tube 56 provided in opposition to each of the opposite ends of a multiply perforated planar fireproof block 73 is connected to an adjacent inner wall 54 by a connection plate 61. And a pilot burner 76 with a discharge ignition device for forming a flame is provided between the plate 61 on one side and the block 73. The presence of the plate 61 and the tube 56 connected by the plate 61 restrains a flame 28 and a flow of combustion gas produced by the flame 28 at a burner port 76a of the burner 76, and hence even if the flame 28 is formed, a small flame 28a formed on the burner 76 is not put out. Thus mixed gas 27 can be surely ignited by the flame 28a of the burner 76.

Filed: 1994-07-19
Abstract: PURPOSE:To obtain a line drawing image of high quality even when an image is enlarged. CONSTITUTION:An emphasis processing part 31 performs emphasis processing for density data on an aimed pixel and its peripheral pixels. The value obtained by the emphasis processing part 31 is multiplied by a coefficient M at a 1st multiplication processing part 321. For the density data, a smoothing processing part 33 performs smoothing processing and when an image selected with an image selection key 6 is the line drawing image, a threshold value processing part 34 performs threshold value processing for the value obtained by the smoothing processing part 33. A 2nd multiplication processing part 322 multiplies the value obtained by the threshold value processing part 34 by a coefficient N. When the image selected with the image selection key 6 is the line drawing image, M is set to N. Then an addition processing part 35 adds the output value of the 1st multiplication processing part 321 and the output value of the 2nd multiplication processing part 322 together and outputs the result as density data on the aimed pixel to an image formation part 7.

Title: Manufacture of high density wiring board
Inventor: MINAMI NOBUYUKI
IPC: H05K3/10
Filed: 1990-06-26
Abstract: PURPOSE:To improve insufficient burying of the end of a wire by cutting an insulated wire, then setting the output of an ultrasonic oscillator to the same as that at the time of wiring the wire, and burying the end of the wire in an adhesive layer. CONSTITUTION:When a time for once stopping a stylus for cutting a wire is approached, the moving speed of the stylus is started to be decelerated, and the output of an ultrasonic output unit is started to be reduced. A wiring machine stops moving of the stylus, stops its magnetostrictive vibration and cuts the wire. In this case, since the controller of the machine receives a wire cut signal, it set the output of the oscillator to the same as that at the time of wiring at a high speed constant speed during a period after a predetermined time is elapsed. Thus, even if the moving speed of the stylus is slow in a wiring region at the end of the wire after the wire is cut, since the output of the oscillator is large, the adhesive layer is sufficiently dissolved, the end of the wire is buried in the layer so that the end is not floated.
