Title: Incomplete combustion detecting device for space heater
Inventor: MORIMOTO SATOSHI
IPC: F23N5/20
Filed: 1987-09-08
Abstract: PURPOSE:To control the fluctuation of the sensor resistance incidental to the temperature fluctuation of exhaust gas so as to prevent the detection error of incomplete combustion by providing a gas sensor with a heater, and regularly changing the power supply to the heater. CONSTITUTION:In order to detect the incomplete combustion by causing a gas sensor 2, which utilizes the changing resistance value of metallic oxide semiconductor, to contact the exhaust gas from a burner 02, a means is set up with a switch 20 and a timer 28 which cause the power supply to a heater 6 to regularly fluctuate so that the temperature of the sensor 2 may be alternately fluctuated between the high and low temperature zones. The timer is operated at intervals of 60 seconds, for example, to control the switch 20. During the initial 20 seconds, the switch 20 is turned on to heat the sensor 2 to 300 to 500 deg.C, and during the following 40 seconds, the switch 20 is turned off so as to maintain its temperature in the lower temperature zone of 100 to 200 deg.C by means of the residual heat and the heating by the exhaust gas. At the 40th second, the CO level is measured by way of the resistance value of the sensor 2. In this way, the temperature-dependency of the sensor in the lower temperature zone changes drastically, and it does not indicate the valley type temperature characteristics any more even if the exhaust gas temperature fluctuates.

Abstract: PURPOSE:To make magnified display possible by mounting the shift circuit inputted to a D/A converter and converting the data of the number of quantized bits indicated on the basis of the shift value in digital quantity by the D/A converter. CONSTITUTION:A shift circuit 7 extracts the continuous data 20a (data region) corresponding to the number of quantized bits of a D/A converter 9 on the basis of an indicated shift value from the data width of digital quantity to input the same to the converter 9. Since the converter 9 outputs the max. value of the extracted data region in a ful scale, if the shift value 21 is indicated, the waveform of the digital quantity 20 can be arbitrarily displayed in a magnified state by the converter 9 further reduced in the number of quantized bits. That is, since the D/A converter having resolving power lower than that of sampling data can be used, cost reduction can be achieved.

Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent ink from running straight by making a region where a tip is connected to an ink storage part displaceable in a width direction with a barrel longitudinal direction and engaging a sliding piece with an operating body in such a manner that the former moves forward/backward and further arranging a pressing spring between the rear part of the operating body and the rear part of the sliding piece. SOLUTION: In such a state that a tip 11 is turned downward for writing, a ball valve 16 comes into contact with the rear end of the tip 11 in such a way that the former is deflected to one of the sides of the latter and an ink flow path for ink to flow in is formed on the other side in the tip 11. The ink 18 which flows into a valve chamber 7 from an ink storage pipe 17 through a guide hole 9 is conducted upto the back face of a tip ball 12. Under this state, a bar axial part 15 is pressed to make the tip ball 12 come into contact closely with the inner edge of a tip embracing part and thus the ink is prevented from running straight. Besides the tip ball 12 is minutely moved backward by a pen pressure, enabling the ink to flow out through a generated gap. Further the ink runs smoothly by the rotation of the tip ball 12 when the pen is used for writing. Thus it is possible to obtain the handwriting with high density without a blot.
