IPC: C07J41/00
Filed: 1982-06-08
Abstract: NEW MATERIAL:The steroid glycoside of formula I -formula IV (R is H or acetyl; Z is group of formula V). USE:Useful for repelling harmful fish such as shark. Ensures the safety of divers working in waters in which the harmful fish lives. PROCESS:The poison gland of a poisonous fish, MINAMI-USHINOSHITA (a fish of Cynoglossidae family) is stimulated, and the exuded viscous liquid is freeze- dried. The dried product is suspended in 0.1N ammonia water, diluted with acetone, left to stand, and filtered. The solvent is removed from the filtrate, and the residue is suspended in 0.1N ammonia water, and extracted thrice with ethyl acetate. The organic phase is evacuated to remove the solvent and obtain the residue, which is eluted by normal pressure column chromatography successively with chloroform and 3%, 10%, 25% and 50% methanol/chloroform mixture. The fraction eluted by 10% methanol/chloroform mixture is collected, and the solvent is removed under reduced pressure. The compound of formula I wherein R is acetyl can be separated from the residue.

Title: Power generation apparatus for vehicle
Inventor: TSUTSUI TOSHIO
IPC: H02P9/30
Filed: 1995-04-24
Abstract: PURPOSE: To supply the leading current of a synchronous generator for a vehicle in a simple circuit constitution and to improve a power generation state and a vehicle state. CONSTITUTION: In a power generation apparatus, for a vehicle, which comprises an AC generator 100, a quantity of power generation state which is related to the power generation state of the AC generator 100 and which is changed by the supply of a condensive current to the generator 100 is detected. When it is judged on the basis of the detected quantity of power generation state that the supply of a leading current to armature windings 5a, 5b, 5c is required, the leading current is supplied to the armature windings 5a, 5b, 5c (including a case in which its supply amount is increased). When it is judged that the supply is not required, the supply of the leading current is stopped (including a case in which its supply amount is reduced).  Thereby, when it is required to change (improve) a power generation state, e.g. by an output increase by the supply of the leading current, the leading current is supplied so as to realize its change (its improvement). When it is not required to change the quantity of power generation state by the supply of the leading current, the supply of the leading current is stopped. Thereby, it is possible to suppress a trouble due to the supply of the leading current, especially the change rate of an output current, i.e., an increase in ripples.
