Title: Leakage current measuring system
Inventor: AKATANI MASAMI
IPC: G01R31/02
Filed: 1985-03-19
Abstract: PURPOSE:To enable to obtain active component and reactive component of leakage current simply and at high accuracy by using a general-purpose clamp type leak meter and adding a simple additional circuit. CONSTITUTION:The body of a leak meter LM amplifies and rectifies secondary side current of a current transformer CT and an indicating ammeter is also unified. Tertiary winding and a bias coil La to let flow bias current is wound on a transformer CT. An adapter AD adjusts bias current to a coil La to a specified value. A neutral point (t) is provided in a descending transformer Tr and secondary low voltage side. Secondary side of the transformer Tr is connected to a bridge by a three-terminal variable resistor VR, and a resistor R and coil La are connected in series between the neutral point t and the sliding terminal of the resistor VR. As secondary side of the transformer Tr is loaded by resistance of a high value, bias current becomes the same or reverse phase to the phase of power source voltage. The phase can be reversed and the value of bias current can be changed by changing the resistance VR.

Title: Mixing ratio controller for burner
Inventor: MORIMOTO KAZUYUKI
IPC: F23N5/18
Filed: 1990-03-07
Abstract: PURPOSE:To provide a compact and less-expensive mixing ratio control device for a burner capable of preventing any erroneous sensing caused by a dew formation by a method wherein means for sensing a mixing ratio between gas and air is constructed such that a bypath for communicating a gas supplying passage with an air supplying passage is provided with an air speed sensor. CONSTITUTION:In a mixing ratio control device for a burner, a bypath B1 for communicating a gas supplying passage G1 with an air supplying passage A1 is provided, wherein its bypath B1 is provided with an air speed sensor 10. When a pressure difference occurs between the gas supplying passage and the air supplying passage, air having an air speed corresponding to the pressure difference is generated in the bypath. Accordingly, sensing of its air direction and air speed enables the pressure difference to be detected by sensing them with an air speed sensor. Since the bypath is used for communicating both supplying passages, a dew formation is hardly generated and even if the dew formation occurs, it may be removed by an air purging or the like.

Title: Car air conditioner
Inventor: SHIKAMURA AKIO
IPC: B60H1/32
Filed: 1984-03-22
Abstract: PURPOSE:To simplify a fresh air leading system and to make it possible to restrain that warmed air or cooled air is scattered wastefully, by setting an inner air intake and its opening/closing damper, in front of the condenser of a condensing unit. CONSTITUTION:On the bottom face of the housing D of a condensing unit, an inner air intake 11 and its opening/closing damper 12 are set, in front of a condenser 9. When car room inner air is contaminated and an inner air/outer air change-over damper 6 is changed to the outer-air-side, the damper 12 is opened in linkage with the damper 6, hotness or coolness contained in the inner air is absorbed, while the inner air is passing through fin gaps of the condenser 9, as it is sucked by the negative pressure made by an exhaust fan 10, the inner air is mixed with the condenser cooling air which is taken from an air intake, and is exhausted outside from an air outlet 8. Consequently, it is not necessary to set a contaminated air exhaust opening and its forced ventilating fan, because the outer air can be easily led into the car room, and it can be restrained that warmed air or cooled air is scattered wastefully.
