Title: Organic thin film
Inventor: NAITO KATSUYUKI
IPC: H01L31/04
Filed: 1990-09-19
Abstract: PURPOSE:To obtain a uniform and stable amorphous organic thin film by incorporating at least one of triphenylamine derivative stereoscopically asymmetrical as an entire molecule and p-diphenoquinone derivative stereoscopically asymmetrical as an entire molecule. CONSTITUTION:Substituent groups of three phenyl groups have different two or more triphenylamine skeletons in such a manner that the two or more skeletons are different from each other, and contains at least one of triphenylamine derivative stereoscopically asymmetrical as an entire molecule and p-diphenoquinone derivative stereoscopically asymmetrical as an entire molecule. The triphenylamine derivative or the p-diphenoquinone derivative has phenyl group introduced with the same substitutent group, and lowers its crystallinity as compared with that having partly excellent symmetry so that an amorphous state becomes stable. Since the triphenylamine derivative has two or more triphenylamine skeletons, a decrease in thermal resistance due to an increase in a molecular weight can be avoided.

Title: Lighting device for motorcycle
Inventor: YAMAGUCHI MASASHI
IPC: B62J6/00
Filed: 1983-12-29
Abstract: PURPOSE:To reduce the number of parts items, by using each filament of a turn signal lamp and a driving indicator lamp in common, while controlling switching speed in a load current flowing into these filaments, and combining both turn signal and driving indicator lamps in coommon use. CONSTITUTION:Each of lighting devices 5a and 5b is controlled by a control circuit using a microcomputer 17. When a numerical value of a pulse signal out of a counter 23 accords with the specified value written in an interruption register 24, an interruption program is processed. When these lighting devices 5a and 5b come to turn signal lamps, switching speed in a load current is slow as in illustration (a) whereby time T for on-time A and off-time B is in a state being long and flashed. Likewise, when these lighting devices 5a and 5b come to driving indicator lamps, the switching in the load current is swift enough as in illustration (b) whereby the time T for on-time A' and off-time B' is short, coming to T>T' which is seen as if it comes into a state of being lighted for human eyes. With this constitution, in time of driving indicator lamps, it is processed with an interruption routine and in time of turn signal lamps, it is processed with a main routine.

Filed: 1984-11-30
Abstract: PURPOSE:To reduce the heat generation in a light load such as X-ray fluoroscopy to improve the reliability by providing a lamp voltage generating portion for X-ray photograph and a lamp voltage generating portion for X-ray fluoroscopy. CONSTITUTION:The first and the second lamp voltage generating portions 7, 8 comprise the first and second switching means 3a, 3b for switching the output of rectifying-smoothing means 2, respectively, the first and the second high tension transformers 4a, 4b and the first and the second rectifying means 5a, 5b, and they output a lamp voltage for providing the generation of X-rays for X-ray photograph and a lamp voltage for providing the generation of X-rays for X-ray fluoroscopy. The controlling portion 9 operates the first lamp voltage generating portion 7 in the X-ray photograph and operates the second lamp voltage generating portion 8 in the X-ray fluoroscopy. Since the supplying power to a X-ray tube 6 is small in the X-ray fluoroscopy, it is possible to make the primary inductance of the second transformer 4b larger than that of the first transformer 4a, and thus it is possible to restrain the primary current of the transformer 4b to a small value.
