Filed: 1990-02-06
Abstract: NEW MATERIAL:A benzotriazole compound expressed by formula I (R is lower alkyl; X is halogen). EXAMPLE:5-chloro-2-(3-methyl-2,4-dihydroxyphenyl)benzotriazole. USE:Intermediate of various resin, ultraviolet absorber for latex and cosmetic, etc., or industrial chemicals such as photographic agent. PREPARATION:A compound expressed by formula II is subjected to diazotizing reaction together with nitrous acid such as sodium nitrite or potassium nitrite in acidic medium such as hydrochloric acid or sulfuric acid, etc., to obtain a diazonium salt expressed by formula III and a compound expressed by formula IV is dropped to subject to diazo coupling reaction to obtain a compound expressed by formula V. Furthermore, said compound is reduced with zinc dust in the presence of alkali such as sodium hydroxide to afford the compound expressed by formula I. Besides, said compound is advantageous in using operation because of having high solubility in water in contrast to conventional benzotriazole-based ultraviolet absorber.

IPC: B21B37/00
Filed: 1979-03-09
Abstract: PURPOSE: To make possible the shape control over a wide range during performing the rolling work, by suitably combinedly controlling the roll bending and the displacement of the intermediate roll depending on the transverse tension distribution in the strip.  
     CONSTITUTION: The transverse tension distribution of the strip 1 is detected by the electromagnetic pickup 6 on the delivery side of the rolling mill 5, and the shape discriminator 7 discriminates the existence and degree of the edge wave and center buckle, and inputs the discriminated result to the arithmetic unit 15.

Title: Optical controller
Inventor: SHIBATA KENICHI
IPC: G01J5/0805
Filed: 1984-02-15
Abstract: PURPOSE:To constitute a small-sized optical controller by providing a displacing body which varies the relative position relation between a couple of facing bodies which face each other, a couple of light passing windows which do not face each other across the couple of facing bodies, and a light varying means which directs light from one passing window to the other light passing window. CONSTITUTION:Oscillators 21 and 22 oscillates on the basis of voltages applied to the 1st and the 2nd terminals 7 and 8. For example, when a +5V DC constant voltage is applied to the 2nd terminal 8 and a +35V and a -25V voltage are applied to the 1st terminal 7 alternately at a 3-5Hz period, the oscillators 21 and 22 oscillate accurately in the opposite directions as shown by S and S'. The facing bodies 35 and 36 vary in relative position relation on the basis of the oscillations and the light passing parts 37 and 38 are placed in the state wherein they are superposed on one another and opened and the state wherein they are not superposed on one another and closed alternately and repeatedly; for example, when an object of temperature measurement faces the 1st light passing window 5 and an infrared light temperature sensor faces the 2nd light passing window 6, infrared light from the body to be measured enters a storage body 2 through the 1st light passing window 5 and modulated periodically and intermittently by the facing bodies 35 and 36, and then the light is changed in traveling direction and made incident on the sensor to measure the temperature precisely.

IPC: H03F3/45
Filed: 1978-03-13
Abstract: PURPOSE:To make it possible to obtain a stable output signal, even if there is dispersion of characteristics of a transistor, with the wide range of an input voltage level by connecting loads whose impedance increases according to a rise in potential. CONSTITUTION:The 1st loads 1 and 2 are connected in series to MOSFETs 3 and 4 respectively to form series circuits 5 and 6, and the 3rd load 12 supplied with the potentials of connection points 10 and 11 is connected between connection points 7 and 8. Load 12 functions to increase the impedance according to the rises in potential of connection points 10 and 11 and, for example, when input voltage levels to gates of FETs 3 and 4 are low, potentials of connection parts 10 and 11 increase to increase the impedance of load 12 and, in consequence, currents of circuits 5 and 6 are also increased, thereby decreasing potentials of connection parts 10 and 11. Namely, potentials of connection parts 10 and 11 become stable at certain values through the feedback function of load 12. Consequently, variations in output potential of connection points 10 and 11 can be reduced even if gate input voltages of FETs 3 and 4 vary over the wide range.
