Title: Fuel pumping-up type petroleum burner
Inventor: NAKAMURA KAZUHARU
IPC: F23N1/00
Filed: 1978-12-27
Abstract: PURPOSE: To facilitate airflow control and provide optimum balance in relation to oil amount by a method wherein a constant oil surface level device is fitted with an overflow pipe having a tip end in a position slightly lower than the tip end of an oil feed pipe faced to a combustion portion, and the other end of the overflow pipe is immersed in oil in an oil tank.  
     CONSTITUTION: With a motor 13 driven, a blower and a pumping-up pump 9 rotate, and oil in a tank 8 is fed to a constant oil surface level device 1. With an airflow regulator damper 6 opened by rotating an operating knob 14, combustion air from the blower is fed to a combustor 2 via a blasting pipe 4, and the blasting pressure is applied to the device 1 via a branch pipe 5. At this time, the lower end of an overflow pipe 7 is immersed in the oil in the tank 8, so that the blasting pressure cannot be relieved but pushes the oil surface down. Thus, the oil pressure in the device 1 increases, and the oil is pushed out from the tip end of an oil feed pipe 3 into the combustion portion 2. The discharged oil amount varies in proportion to the variation of fuel and air amounts by the open-close operation of the damper 6.

Title: Video signal transmitter and screen copying device
Inventor: TAKAHASHI YASUHIKO
IPC: H04N5/91
Filed: 1991-06-10
Abstract: PURPOSE:To provide a video signal transmitter and a screen copying device which can transmit and reproduce the accurate video signals without casing any off-synchronized state. CONSTITUTION:A video signal transmitter converts the inputted analog composite video signal into a digital composite video signal to transmit this signal via a communication cable 41. At the same time, the transmitter produces a window signal from an input analog video signal and transmits this signal via a window signal line 42 in order to extract a synchronizing signal out of the digital composite video signal. A printer extracts the synchronizing signal out of the digital composite video signal base on the received window signal. Then the printer controls the print timing based on the extracted synchronizing signal and perform the copying print of screens. Thus no off-synchronized state is caused since the window signal is transmitted via the independent line 42 for extraction of the synchronizing signal and then the synchronizating signal is reproduced.

Title: Frequency generator
Inventor: OBATA SHIGEO
IPC: H02K21/24
Filed: 1985-07-26
Abstract: PURPOSE:To obtain a frequency generator (FG) having a high output and high precision by mounting a coil for the FG of a plurality of turns and displaying an effect of the arrest of noises by the drawing-around of a pattern wiring for the FG coil. CONSTITUTION:Magnetic flux crossing a generating wire element 5 for a FG coil changes with the revolution of a rotor yoke 8 on which a multipolar magnet 7 is fixed, and speed signals corresponding to the speed of revolution are generated at output terminals 1, 2. Since a coil having a plurality of turns is shaped in the FG coil at that time, the number of the generating wire elements 5 is multiplied in succession, and generated voltage is also increased in proportional to the number of turns of the FG coil, thus resulting in strengthening against the jump-in of noises. A connecting wire 3 joining the FG coil and the output terminal 1 is similar to a crossover 4, and the direction of currents flowing through the connecting wire 3 and the direction of currents flowing through the crossover 4 are mutually directed oppositely, thus arresting noises even on the generation of noises.

Abstract: PURPOSE: An aqueous dispersion of vinyl chloride resin to be processed into paste is treated with a plasticizer or with both of a plasticizer and an organic solvent to remove water from the product, thus giving the high-quality resin paste sol without heating and drying steps.  
     CONSTITUTION: An aqueous dispersion containing 25W80wt% of vinyl chloride resin that is obtained by polymerization of vinyl chloride monomer or a monomer mix mainly containing the same in an aqueous medium and is to be processed into paste is mixed with 20W1,500pts.wt. of a plasticizer and 0W40pts of an organic solvent per 100pts of the vinyl chloride resin. The addition causes the vinyl chloride resin to shift into the plasticizer layer or mixture layer thereof with the organic solvent, resulting is separation of the aqueous layer. Then, dehydration is effected to give the vinyl chloride resin paste sol. Heating and drying steps can be eliminated and the deterioration can be prevented in the quality of the paste sol.

A line lwith the inclination theta, that is y=ax+b, is changed to decide (b) with which all the points satisfy y<=ax+b in the range of the product length L1. Taking the line having the inclination theta for an initial value, the line l is moved in the direction (y) and then stopped once, the line l is further moved in parallel in the direction (y) to stop at a point where the product width is W, where a line L perpendicularly crossing the line l is moved in the direction (x) from the forward end of the steel plate, and a size measuring position is decided.

Title: Water leak detector
Inventor: FUKAMI YASUMASA
IPC: G01M3/16
Filed: 1986-07-15
Abstract: PURPOSE:To simply discover abnormality such as disconnection of a cable for connection between a water leak detector body and a sensor, by arranging a resistor and a checker connected through a switch means in parallel with an electrode of a water leak sensor. CONSTITUTION:A resistance value between electrodes of a sensor 6 is several MOMEGA when a dry condition is therebetween and current flowing through a resistance connected to a negative terminal of a comparator Co is small while a voltage at the negative terminal is smaller than that at a positive terminal and a lamp L and a buzzer Bz are OFF. As the resistance between the electrodes falls with water building up between the electrodes of the sensor 6, the voltage at the negative terminal of the comparator Co rises so high that the lamp L and the buzzer Bz are activated to alarm about water leak. When a check switch SW is turned ON, a transistor Q is activated to connect a resistance R1 in parallel between the sensor electrodes. Since the resistance R1 is the same as the resistance value as given when a water drop is attached between the electrodes, the voltage at a negative input of the comparator Co rises to activate the lamp L and the buzzer Bz together. Thus, the cable 5 is determined to be normal.

IPC: H04B10/14
Filed: 1990-06-26
Abstract: PURPOSE: To facilitate the replacement of a laser module and to reduce the waste of time by deciding a power level of a transmission signal that is needed to properly modulate laser from the operation characteristic value of a laser module and adjusting the size of a transmission signal input to the level described above. CONSTITUTION: The required level of a transmission signal to modulate laser when an inclined capability, i.e., the rated power of SE laser is Pnom, and modulation degree is M which desires that input impedance is R is calculated by the following expression. L=1/2×(Pnom/SE)<2> ×R×M<2> . An operational characteristic is decided by deciding input power intensity that is needed to operate 100% modulation. When a new laser module is replaced, a microprocessor measures the characteristic of the installed laser module according to the expression and decides an analog signal level that is needed for the input part 38 of the module based on the characteristic. Then, it measures an actual analog signal level to laser and adjusts it to a calculated level.
