Abstract: All two-character chains including two general characters and all three-character chains including one special character between two general characters are detected from a registration character string in which a large number of special characters not having any meaning are frequently arranged, or all two-character chains including two general or symbolic characters are detected from a converted registration character string produced by changing each special character of the registration character string to one type of symbolic character determined in correspondence to one general character adjacent to the special character. Also, occurrence frequencies of the general or symbolic characters of each chain are counted and stored in a recording medium with the registration character chains.

Abstract: Supertwist liquid crystal displays having very short switching times are obtained if the nematic liquid crystal mixture contains at least one component chosen from group A consisting of compounds of the formulae AI to AVI: wherein R1 and R2 in each case independently of one another are each R and R is alkyl having 1-12 C atoms, wherein one or two non-adjacent CH2 groups can also be replaced by —O—, —CH═CH—, —CO—, —O—CO— or —CO—O—, and up to four other components.

Abstract: Supertwist liquid crystal displays having very short switching times are obtained if the nematic liquid crystal mixture contains at least one component chosen from group A consisting of compounds of the formulae AI to AVI: ##STR1## wherein R.sup.1 and R.sup.2 in each case independently of one another are each R and R is alkyl having 1-12 C atoms, wherein one or two non-adjacent CH.sub.2 groups can also be replaced by --O--, --CH.dbd.CH--, --CO--, --O--CO-- or --CO--O--, and up to four other components.

Abstract: A division code is added to both ends of a group of pieces of data registered in an item of a data record L and between each pair of adjacent data, so that a piece of code-added data is produced. Thereafter, a character chain pattern (C1,C2) of each pair of adjacent characters C1 and C2 in the code-added data is prepared, an occurrence frequency Fi of each character Ci in each piece of data H is calculated, and character chain information (F1,F2,H,L) corresponding to each character chain pattern (C1,C2) is prepared. Therefore, a index file in which pieces of character chain information prepared for the same item of a plurality of data records are listed is prepared. When a keyword is input by a user, the division code is added to both ends of the keyword to produce a code-added keyword, and a series of keyword character chain patterns is prepared from the code-added keyword in the same manner.

Abstract: A plurality of characters arranged in a text are numbered in order of occurrence for each character type, and an occurrence number table in which one or more occurrence numbers are listed for each character type is prepared in an occurrence number preparing unit. Also, a set of two character types is defined as a character pattern, and a set of two occurrence numbers of two adjacent characters of which types correspond to one character pattern is defined as an occurrence number pattern. One or more occurrence number patterns respectively corresponding to one character pattern are arranged for each character pattern, and a list of occurrence number patterns is prepared as an index file in an index file preparing unit.

Abstract: There is disclosed an evaluating apparatus for evaluating a manipulation performance of a commodity with operating parts. Three dimensional position and orientation of a first body like an operator's fingertip is detected to virtually display the first body. Also, configuration and functions of operating parts planned to be attached to a commodity are set, and three dimensional position and orientation of a second body like a commodity model having the same external shape as that of the commodity is detected to virtually display the commodity with the operating parts. When a planned area of the second body is manipulated by the first body, a contact of the second body with the first body is detected, and an operating part Po placed at a position corresponding to the planned area is detected. Thereafter, the operating part Po of which an external shape is virtually changed by the manipulation of the first body is displayed according to the configuration and function of the operating part Po.
