Title: Faraday rotary switch
Inventor: UEDA KENICHI
IPC: G02F1/09
Filed: 1985-10-31
Abstract: PURPOSE:To equalize a dielectric constant of the periphery of a magnetic field generating coil and to prevent a dielectric breakdown by using water as a Faraday rotary medium, and immersing the magnetic field generating coil into the water. CONSTITUTION:Ultraviolet rays which have been irradiated in the direction as indicated with an arrow B are polarized linearly by a polarizer 1 and transmit through in water 5. In this case, if a current I flows to a magnetic field generating coil 3, and a magnetic field H is applied to the water 5, when the ultraviolet rays transmit through the water 5, its plane of polarization rotates by 90 deg., becomes parallel to the polarization direction of a polarizer 2 and the ultraviolet rays pass through the polarizer 2. On the other hand, when the magnetic field generating coil 3 is not conducted electrically, the plane of polarization of ultraviolet rays does not rotate at all, when passing through the water, the plane of polarization of ultraviolet rays becomes orthogonal to the polarizating direction of the polarizer 2 and the ultraviolet rays are cut off by the polarizer 2. In this way, since the magnetic field generating coil 3 has been immersed into the water 5 filled in a sealed case 7, a dielectric constant of the periphery becomes uniform, an electric field concentration is not generated, and a dielectric breakdown can be prevented.

Title: Switching regulator
Inventor: ISHIKAWA YUICHI
IPC: H02M3/335
Filed: 1985-10-31
Abstract: PURPOSE:To prevent an oscillation transistor from damaging by canceling the magnetic flux of a choke coil of a blocking oscillator, and turning ON the transistor after the exciting energy is completely discharged. CONSTITUTION:A blocking oscillator of a witching regulator is composed of a transformer T having windings L1-L3, and a transistor (Tr) Q. In this case, a voltage drop circuit R having a series circuit of a diode D2 and a resistor R3 is connected in parallel with a series circuit of a diode D1 and a resistor R2 with the base of Tr Q to stop a current in a very low voltage range. Thus, in the blocking oscillator TR Q tends to turn ON due to the erasure of the magnetic flux of the transformer T, but a voltage is generated in the base winding L3 until the exciting energy is completely discharged from a choke coil L, it still remains in OFF state. As a result, it can prevent Tr Q from damaging due to a surge current.

Title: Sodium sampling apparatus
Inventor: HAINO HIROSHI
IPC: G01N1/10
Filed: 1989-09-22
Abstract: PURPOSE:To prevent impurities in sodium from moving by making the position of the inlet nozzle of a sampling container higher than that of an outlet nozzle. CONSTITUTION:Sodium flows into a sampling container 1 via an inlet piping 4 and an inlet nozzle 2 and flows out via an outlet nozzle 3 and an outlet piping 5. When, after sodium is accumulated in the container 1 and continued to flow until the effect of traces of impurities possible to attach inside at an early stage is removed, the flow of sodium is stopped, part of sodium in the nozzle 2 above the openings of the container 1 flows down therein, a liquid level in the container 1 is lowered to the opening of the nozzle 3 and the liquid level in the nozzle 3 is below that of the container 1. Therefore, sodium in the container 1 is separated from that in the pipings 4 and 5 and impurities are prevented from moving between sodium in the container 1 and that in the pipings 4 and 5 due to a segregation generated while sodium is cooled. Thus, the reliability of a sample can be increased.
