Patent JP-H05146061-A (JP)
Title: Dc transmission facility
Inventor: KUWABARA TAKASHI
IPC: H02J1/00
Filed: 1991-11-18
Abstract: PURPOSE:To obtain a DC transmission facility requiring no expensive DC circuit breaker by making a decision whether a voltage detected at a neutral point has a polarity of plus or minus and then controlling the firing phase of thyristor in an A/D converter based on an output signal. CONSTITUTION:When a DC current ia is higher than ib in a bipolar DC transmission system, differential current between ia, ib flowing through a metallic return line 8 flows from a ground point 9 toward a neutral point 10. In other words, DC voltage at the neutral point 10 has a minus level with respect to the ground point 9. A minus decision output is fed from a polarity decision unit to a controller 15 which then controls the firing phase of thyristors in A/D converters 5, 6 to reduce the DC current ia. The control is performed until a DC voltage detector 13 detects zero voltage at the neutral point 10. When the DC current ib is higher than ia, a plus voltage appears at the neutral point 10. According to the constitution, voltage on the metallic return line can be constantly kept at zero level.

Title: Formation of resist pattern
Inventor: NAKAMURA HIROKO
IPC: G03F7/11
Filed: 1986-12-19
Abstract: PURPOSE:To prevent charge up by using a conductive film of polybeta-diketone as a flattening layer. CONSTITUTION:The polybeta-diketone layer is formed as the flattening layer on a semiconductor substrate, for example, Al/Si substrate in formation of a resist pattern for which multi-layered resist layers having conductive films are used under a resist layer. After the resist layer is then formed, the layer is patterned. Since the polybeta-diketone has conductivity, the charge stagnating in the resist on the polybeta-diketone layer flows through the polybeta-diketone to the semiconductor substrate. The charge up is thereby prevented.

Title: X-ray ct detector
Inventor: AKAI YOSHIMI
IPC: G01T1/20
Filed: 1989-11-22
Abstract: PURPOSE:To prevent the lowering of the image quality of a display image due to the deterioration of the radiation of a scintillator by transmitting the light generated from a fading light source through a reflecting film to allow the same to be efficiently incident on the scintillator. CONSTITUTION:A colored part is generated in a scintillator 2 by the irradiation with X-rays at the time of the photographing of an object and the output of light lowers. After the completion of photographing, when the scintillator 2 is irradiated with the generated light (t) of a fading light source, an interference film 9 has high transmitivity to the light (t) and, therefore, the light (t) transmits through the interference film 9 to be efficiently incident on the scintillator 2 to perform the fading of the colored part and the lowering of the sensitivity of an X-ray CT detector due to the deterioration of radiation can be prevented and, as a result, the fluctuation of a CT value or the generation of an artifact is reduced and the deterioration of image quality can be prevented. Since the reflecting film 9 reflects the generated light of the scintillator 2 with high reflectivity, the generated light is efficiently incident to a photodiode 3 in cooperation with the reflection due to white paint and detection sensitivity can be enhanced.
