Abstract: PURPOSE:To reduce the cost of a small-sized and high-reliability power supply switching circuit by providing a Zener diode, the first photocoupler, an inverting transistor Tr, and the second photocoupler and switch the power to supply it to the first or the second load. CONSTITUTION:When a voltage higher than a Zener voltage is applied to an input terminal 1, a Zener diode 2 is made conductive, and about 1V DC voltage is applied to the first photocoupler 4 through a resistance 3 to make it conductive. A voltage applied from a power regulator 6 is supplied to a circuit 8, to which power is supplied, through a photodetector of the photocoupler 4. Simultaneously, about 1V DC voltage is applied to the base terminal of an inverting Tr11 by voltage dividing resistances 9 and 10, and the Tr11 is made conductive, and the second photocoupler 13 is turned off. Next, when a DC voltage lower than the Zener voltage is applied to the input terminal 1, the diode 2 is cut off, and the photocoupler 4 is turned off, and power is not supplied to said circuit 8. Meanwhile, about 1V voltage is applied to the photocoupler 13 through a resistance 12 because the Tr11 is turned on, and the photocoupler 13 is turned on, and power is supplied to the second load 14.

Title: Finger picture input device
Inventor: TAKEDA MASAHIRO
IPC: G06K9/00
Filed: 1990-03-23
Abstract: PURPOSE:To prevent an image by a finger guide from coming out in an obtained picture, and to obtain the finger picture of good quality free from the influence of the finger guide by preventing the finger guide from being in contact with the finger contact surface of a finger placing stand. CONSTITUTION:The finger guide 2 is attached to, for instance, the supporting member 6 of a prism 1 so as not to be in contact with the finger contact surface of the prism 1. Besides, the finger guide 2 is arranged at the right side of the finger contact surface of the prism 1, and is set so that its one side along which a finger 5 is to be laid is parallel with the longitudinal direction of the prism 1, and in addition, the direction of it is adjusted so as to intersect the scanning direction of a television camera 4 at right angles. Thus, since the finger guide 2 is arranged so as not to be in contact with the finger contact surface of the prism 1, light from a light source 3 is total-reflected by the finger contact surface just below the finger guide 2, and as the result, the finger guide never exercises influence upon the picture to be image-picked up by the television camera 4 at all.

Title: Polymerization catalyst for olefin
Inventor: HIRUTSUKA KUNUUTEIRA
IPC: C08F4/06
Filed: 1991-01-16
Abstract: The present invention concerns a polymerization catalyst of olefins, said catalyst containing an active chromium compound on an inorganic support. The catalyst in accordance with the invention is prepared by vapourizing a precursor of chromium oxide such as chromyl chloride and allowing the chromium oxide vapour to react with the surface of, e.g., silica gel support material at 160...500 DEG C. A selective binding of the chromium oxide to the support material is achieved by keeping the vapour pressure sufficiently high and the duration of interaction with the support sufficiently long so as to maintain an excess of the chromium compound in relation to the number of available binding sites on the support material. The activity of a catalyst in accordance with the invention even with a very low content of catalytic metal is as high as the activity of a catalyst of an appreciably higher metal content that has been prepared by the methods of the conventional technology.
