Title: Supplementary fuel introduction equipment of internal- combustion engine
Inventor: SUZUKI TERUKAZU
IPC: F02M25/022
Filed: 1983-08-15
Abstract: PURPOSE:To promote complete burning of CH fuel by electrolyzing water into hydrogen and oxygen at the engine driving time and sending them at an appropriate ratio into the cylinder of an engine. CONSTITUTION:An electrode plate disposed inside the primary chamber A which is formed by dividing a water tank 1 by a middle partition plate 3 is fed with an electric current along with starting an internal-combustion engine, water is electrolyzed into hydrogen and oxygen and they float up. Fine water drops are removed by a draining plate 4 and hydrogen and oxygen, as being separated from each other, pass through the gap 6 between the tank and the drawing plate 4 and the gap 2 between the tank and the middle partition plate 3 sequantially and then flow into the secondary chamber B. Air is sent by a pump P via a duct 5 into a chamber B to generate air bubbles from a bubble generator 8. The air bubbles are broken on the water surface into dew-like particles so that hydrogen and oxygen are mixed therewith at an optimum ratio and flow through a supply pipe 7 into the cylinder of the engine. Complete burning of CH fuel may be thereby promoted.

Abstract: PURPOSE:To prevent exposure of a heat transfer pipe to the gas phase part of a generator, to prevent overheating of the heat transfer pipe, and to enable reduction of corrosion of the heat transfer pipe, by providing a controller which increases a delivery amount of a solution pump or reduces a heating amount on a generator when temperature detected by a temperature detector to detect the temperature of the approximate topmost part of the heat transfer exceeds a given value. CONSTITUTION:A title freezer is embedded in the approximate topmost part of a heat transfer pipe 23 in a high temperature generator 1, and is provided with a temperature detector 22 to detect temperature therearound. When the temperature of the heat transfer pipe 23 detected by the temperature detector 22 is increased to a value at least 40 deg.C higher than absorption liquid detected by a temperature detector 24, a controller 25 increases a delivery amount of a solution pump 12 to 100%. In which case, a flow rate of absorption liquid to the generator 1 is increased, and the level of the absorption liquid is raised. When the level of the absorption liquid in the generator 1 is raised to a value high enough to allow the topmost part of the heat transfer pipe 23 to be immersed in the absorption liquid, the temperature of the topmost part of the heat transfer pipe 23 is lowered gradually. When temperature detected by the detector 22 is decreased to approximate 175 deg.C, the controller 25 stops control through which a delivery amount of the pump 12 is increased.

Title: Composite synchronizing signal separator
Inventor: TSUJI MASAYUKI
IPC: H04N5/10
Filed: 1988-06-15
Abstract: PURPOSE:To obtain a composite synchronizing signal separator which hardly receives adverse influences from circumstantial factors, such as a temperature change, etc., by combining plural monostable multivibrators, gates, and FFs. CONSTITUTION:A monostable multivibrator 3 is triggered by a separated horizontal synchronizing signal and generates pulses of a prescribed magnitude. The width of the pulses is set in such a way that the pulses can terminate within vertical synchronizing pulses of odd fields. Another monostable multivibrator 4 is triggered by the tail edge section of the output of the monostable multivibrator 3 and generates pulses of a prescribed magnitude. Since the pulses are gated by composite synchronizing signals, only parts overlapping the vertical synchronizing pulses of odd fields are extracted. A D-type FF 7 is set by the extracted pulses, is reset by the inverted signals of the composite synchronizing signals, and obtains pulselike output. Horizontal and vertical synchronizing signals are separately extracted by using the pulselike output of the FF 7 and the output of the monostable multivibrator 3.

Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To reduce the cost and size of a fire sensor by using a parallel combined resistance of a low temperature linearizing resistance and a high temperature linearizing resistance being thermistor temperature characteristic linearizing resistances as a current limiting resistance for a fire detection display element. SOLUTION: The parallel combined resistance of the low temperature linearizing resistance R1 and the high temperature linearizing resistance R2 being thermistor temperature characteristic linearizing resistances is used as the current limiting resistance for the fire detection display element 7. Namely the parallel combined resistance of both the resistances R1, R2 is used as the current limiting resistance for the display element 7 and a microcomputer 3 having four ports PORT1 to PORT4 is used to constite the fire sensor. Since the parallel combined resistance of the resistors R1, R2 is used instead of a conventional light emitting diode current limiting resistance and a current limiting resistance for a fire detection display element used for a conventional fire sensor is eliminated, the fire sensor can be made low in cost and small in size.
