Title: Double dc power supply circuit
Inventor: WATANABE AKIRA
IPC: H02J1/10
Filed: 1992-05-18
Abstract: PURPOSE:To deal with any failure mode of a double DC power supply circuit, by excluding the voltage drop of its diode for preventing a reverse current. CONSTITUTION:The outputs of two DC power supplies 1, 2 are connected with each other via respective switching elements 3, 4, and an output voltage VO is made obtainable. Also, the output voltage VO is monitored always by a decision device 6, and when the output voltage VO exceeds a predetermined changing limit the decision device 6 outputs the signal for indicating a failure. On the other hand, the output voltages of the two DC power supplies 1, 2 are compared with each other by a comparator 5, and the signal for indicating which output voltage is higher than the other is outputted from the comparator 5. Then, both the outputted signals are sensed by a switching control part 7, and the switching element connected with the side of the faulty DC power supply is switched off.

Title: Gas pipe
Inventor: MIYABE HARUYASU
IPC: F16L9/12
Filed: 1989-07-04
Abstract: PURPOSE:To prevent discharge from bing induced even in a high electric field within a gas pipe by installing an insulating material with cavities such as a plurality of insulating members in a fiber form made of, for example, quartz and resin, in a gas pipe made of a resinous material. CONSTITUTION:A gas pipe 1 through which helium, carbon tetrafluoride and the like flow, is made of a resinous material such as Teflon and the like wherein a plurality of insulating fibers 3 as thin as several mum in size which are made of quartz and resinous materials, are installed within the pipe main body 2 as thin as several mm in size in mutually coiled relation. For example, a gap formed by fibers 3 is smaller than an average free stroke of a single gas molecule. Even if the gas molecule passing through the gas pipe placed in a high electric field is ionized while electrons produced are thereby accelerated, the electrons just collide mainly against the insulating material while probability with which the electrons collide against other molecules, becomes low. This constitution prevents discharge within the gas pipe from being induced, thereby preventing the pipe main body from being damaged due to radiated heat.
