Abstract: PROBLEM TO BE SOLVED: To make the opening and closing motion of a valve element certain and to reduce current consumption by making a turning-on timing to each solenoid of an solenoid driven valve optimum according to a variation in the acting time of the valve element. SOLUTION: The changing over of turning-on to each solenoid is carried out by applying an current to another solenoid after the elapsed time (t2, t5) of a delay time (Tdo, Tdc) from the stop of turning-on to either solenoid. In addition, in the case of turning-on to each solenoid, a temporary depression is detected on an actually flowing current, and a means for correctingly setting a next delay time (Tdo, Tdc) by multiplying a fixed factor to action times (Tmo, Tmc) from the stop of turning-on (t1, t14) to the detection (t3, t6) of the depression in another solenoid is provided. The current supplied to each solenoid is composed of an acting current to open and close a valve element and a holding current to hold the state of the valve element after action.

Title: Preparation of gel using calcium ascorbate
Inventor: MURATA YOSHIFUMI
IPC: C08B37/04
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To efficiently prepare a gel-like composition by using calcium ascorbate capable of exhibiting a gel-forming action in a proper concentration. SOLUTION: This method for preparing a gel-like composition, preferably alginic acid gel, comprises using calcium ascorbate as a gelling agent.

For example, a gel-like composition can be obtained in one step by mixing an aqueous solution of a substance having a gelling ability (preferably sodium alginate) with an aqueous calcium ascorbate solution containing an organic acid (preferably lactic acid, ascorbic acid, gluconic acid, or the like). When reduced ascorbic acid or its salt is used as a gelling agent, the oxidative deterioration of a substance contained in the prepared gel beads can be prevented. Thereby, the gelling agent does not require its washing away after gelled in the gel-like composition, and can be used as a vitamin preparation.
