Title: Evaporating burner
Inventor: MIYAHARA KINGO
IPC: F23D11/04
Filed: 1984-07-28
Abstract: PURPOSE:To perform the starting ignition of unevaporating combustion correctly and eliminate the generation of red flame perfectly by a method wherein an ignition promoting and injection stabilizing ring, bent toward inner side at the tip end of fuel oil scattering position is arranged on inner peripheral surface of a cylinder wall combustion surface. CONSTITUTION:Some part of fuel oil, injected toward the fuel oil scattering position A of a cylinder wall combustion surface 6 by a fuel oil dispersing end 21 provided at the peripheral end of a base end opening side of an evaporating cylinder 11, is prevented by stagnating under swirling current condition due to a negative pressure generated at the bent portion 27 of the ignition promoting and injection stabilizing ring 26 from blowing off to the foward of the combustion cylinder 1 by the combustion air injected from a bottom combustion surface 5, then, the predetermined amount of fuel oil blows and hits an ignition plug 29, therefore, ignition starting is effected rapidly and surely. The fuel oil can effect the unevaporating combustion and the fuel oil is not blown off to the cylinder wall combustion surface 6 side under unburnt condition. According to this method, the generation of the red flame, produced by the flow of fuel oil under unburnt condition into a gas chamber 4 from the gas injection holes of the cylinder wall combustion surface 6, may be eliminated.

Title: Semiconductor integrated circuit device
Inventor: KITANO JUN
IPC: G11C11/408
Filed: 1985-07-19
Abstract: PURPOSE:To balance precharge level at all time even when a power supply source bump occurrs by supplying a timing signal whose potential is raised above the voltage of the power supply source to the gate of a short-circuit MOSFET to equalize the precharge levels in a dynamic differential amplifier circuit. CONSTITUTION:Differential MOSFETs Q3 and Q4 constitute a differential amplifier circuit which receives an input signal supplied from an external terminal, and a reference voltage to identify the high level and low level of the input signal, and is excited by a timing signal. And, the drain precharge voltage of the MOSFETs Q3 and Q4 is shortcircuited by a MOSFET Q5 which is actuated by the timing signal whose potential is raised to a level higher than the voltage of the power supply source. In this way, the level can be maintained constant even if the power supply source bump occurrs, and hence an output signal in accordance with the voltage differential between the two input voltages can be generated. Therefore, a level margin against the bump is secured.

Filed: 1988-06-27
Abstract: PURPOSE:To obtain a stable framing output by comparing the polarity of a signal being the result of frequency-dividing a vertical synchronizing signal with that of a framing signal and correcting the state of a frequency divider circuit only when the polarity of the both is dissident consecutively for a prescribed time or over. CONSTITUTION:The title circuit has a frequency divided circuit 5 inverting the output at each leading of a vertical synchronizing signal and a framing discrimination circuit 6 discriminating the polarity of the framing signal and that of the output of the frequency divider circuit 5, and an H pulse is outputted at an output terminal 63 if the dissidence of the plurality is consecutive for a prescribed time or over, the internal state of the frequency divider circuit 5 is corrected and the polarities at two input terminals 61, 62 of the framing discrimination circuit 6 are made coincident. After the polarity is coincident, since a set input terminal 53 of the frequency divider circuit 5 goes to an L level, the framing output 7 is single frequency division of the vertical synchronizing signal. Thus, even if a signal including noise is given to a video signal input, a stable framing output is obtained.

Title: Clogging prevention in ink globule jetting device
Inventor: MAEDA JIYUNJI
IPC: B41J2/165
Filed: 1984-07-30
Abstract: PURPOSE:To permit preclusion of clogging at an orifice by detecting a change in value of resistance to determine a completion of ink filling during the period of a suspended operation of an ink globule jetting device. CONSTITUTION:After completion of printing operation, a valve device 17 of an ink globule jetting device is changed over and a front chamber 8 is communicated with the atmosphere. If an air pump 14 is operated under the condition, the pressure of ink within the chamber 5 gradually increases in comparison with the pressure within the front chamber 8, and eventually the ink starts flowing from the first orifice into the front chamber 8. And the ink within the air supply pipe 15 rises and wets the detector electrode 23, resulting in, by the ink, a drastic reduction in the value of resistance between the body 22 and the detector electrode 23 and the completion of ink filling is detected. As mentioned above, the ink within the front chamber surely covers the first orifice during the time of suspended operation, resulting in a perfect prevention of clogging due to the main reason of drying of ink at the first orifice.
