Filed: 1988-12-03
Abstract: PURPOSE:To enable the easy adjustment of an operating point and obtain a plurality of switch output levels from a set of light emitting and receiving elements by providing a signal processing circuit for generating switch output when the light receiving quantity of the light receiving element is at the predetermined level. CONSTITUTION:The set output levels Vxa to Vxn of comparators 35a to 35n in the signal processing circuit 33 of a light receiving element 17 are adjusted and set to the predetermined level. As a result, when a ball lens 15 is positioned respectively at points (a), (b) and (c), ON.OFF switch output signal is sent from corresponding output circuits 36a to 36n. Then the contactless switch is fixed to a detected part and then the set output levels Vxa to Vxn of the comparators 35a to 35n are adjusted, therefore, it is possible to accurately set the operating point of switch output. In addition, it is very easy to adjust the operating point. Furthermore, it is easy to constitute a contactless switch having a single or a plurality of operating points by changing only a controller part.

Title: Improvement of cyclodextrin
Inventor: CHIIIRIN JIYAN
IPC: C12P19/18
Filed: 1989-11-27
Abstract: PURPOSE: To increase the production of an α- and the total cyclodextrin by using a specifically treated starch as a substrate when the starch is cyclized to provide the cyclodextrin in the presence of a cyclodextrin glucanotransferase obtained from Bacillus macerans.  
     CONSTITUTION: A raw starch is added to about 60-80% aqueous alcohol solution and treated in an autoclave at a high temperature under a high pressure (e.g. at 121°C, for 8-10 min). Thereafter, the treated product is subjected to a centrifugal separation and the precipitated part is gathered to provide a granular starch easily soluble in cold water. The obtained starch is dissolved in water (in a concentration of 1-10%), and a cyclodextrin glucanotransferase obtained from Bacillus macerans is added to the obtained starch solution. A cyclization reaction of the starch by the Bacillus macerans is carried out at pH 5.5-7.5 and at 40-60°C to provide the objective cyclodextrin.
