Title: Active carbon treated by chitosan for deodorizing and decoloring surfactant and deodorizing and decolorization of surfactant using the same
Inventor: KIKUCHI RYUJI
IPC: C09K23/00
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a method for deodorizing and decoloring a surfactant in which the surfactant can be deodorized and decolored with a simple apparatus according to simple operations at a low cost in a short time without elution into the surfactant by bringing the surfactant into contract with active carbon treated with chitosan used for deodorizing and decoloring of the surfactant. SOLUTION: Chitosan used for treatment of active carbon is an almost colorless and odorless white powder available at a low cost. The chitosan is obtained by deacetylating chitin which is a natural product obtained from shells of crabs and lobsters, has no toxity, irritation and biodegradability and is used as foods, cosmetics and detergents. The chitosan is a polyamine polymer and, therefor, acts as a flocculant to entrap, connect and flocculate the active carbon grains. The active carbon treated by the chitosan is obtained by initially dissolving the chitosan in a dilute acid, suspending the active carbon in the resultant solution, regulating the liquidity to a neutral or an alkaline one, precipitating the chitosan and integrating the chitosan with the active carbon.  The moleculer weight of the chitosan is >=1,000 without limitation thereon if the chitosan may be soluble in the dilute acid. The amount of the chitosan used is 0.05-50 wt.% based on the active carbon.

Title: Dc two-wire type proximity switch
Inventor: UEMURA YOUICHIROU
IPC: H03K17/945
Filed: 1981-07-07
Abstract: PURPOSE:To reduce leakage current at the off-time of a proximity switch and to reduce remaining voltage at the on-time by connecting constant current and constant voltage means to the output terminal of the proximity switch and also connecting a circuit for short-circuiting the constant current means at the on- time of the switch. CONSTITUTION:When an object M to be detected does not approach a detecting coil l of a proximity switch, a signal is not supplied from a detecting circuit A, transistors (TRs) Q1-Q3 are turned off and current I0 supplied from a constant current diode I is the sum of the current consumption IA of a circuit A and the current IZ flowing into a constant voltage diode Z, so that leakage current is not unnecessarily consumed. When the object M approaches the coil l, TRQ1-Q3 are turned on by an output of the circuit A and the constant current source I is short-circuited by the TRQ1. Even if current IB3 flowing into the TRQ3 is small, the current IB3 is compensated by current IR flowing into a resistor R0 and the circuit A is stably driven. The remaining voltage at the on-time of the proximity switch is limited only the voltage VZ applied to the circuit A and the voltage applied between the base and emitter of the TRQ3 and the voltage is not unnecessarily consumed.
