    • PROBLEM TO BE SOLVED: To provide a novel chemical compound having a sufficient enough number of H + in its molecule that has a catalyst activity higher than a conventional heteropolyacid and a high stability as a catalyst, and an efficient method for preparing it. SOLUTION: The heteropolyacid is represented by the general formula (1): H 8 [(PW 11 TiO 39 ) 2 O]-xH 2 O(wherein x is an integer of from 1 to 100). The heteropolyacid represented by the general formula (1) can be prepared by first forming an ether adduct of a heteropolyacid represented by the general formula (1) by a treatment comprising the following steps (A) and (B), and subsequently removing the ether from the resulting ether adduct. The step (A) is a process wherein an aqueous solution comprising a heteropolyacid salt represented by the general formula (2) and TiCl 4 is made acidic by hydrochloric acid. The step (B) is a process wherein an ether is added to an aqueous solution comprising a heteropolyacid salt represented by the general formula (2): K 7 [PW 11 O 39 ]-xH 2 O (wherein x is an integer of from 1 to 100) and TiCl 4 .

    • PROBLEM TO BE SOLVED: To identify a display part even upon the occurrence of a power failure, and ensure low power consumption by applying the constitution that a light source to emit light capable of exciting a phosphor having a persistence characteristic is laid at least at one position of the edge of a photoconducting board. SOLUTION: The prescribed pattern of display part is drawn on the back of a photoconducting board 1, using a phosphor 2 having a persistence characteristic. Also, a light emitting diode as a light source 3 to excite the phosphor 2 of the display part is buried in the edge of the photoconducting board 1. Furthermore, the edge of the photoconducting board 1 is coated with a white substance and a reflector 4 is thereby formed. The phosphor 2 forming the display part, when in contact with light from the light source 3, is excited and emits light. In this case, the emission of light due to photo-excitation continues over a certain time, even when the light source 3 stops emitting light. Also, the display part continues to emit light, while gradually lowering brightness until the next lighting of the light source 3, even when the light source 3 is intermittently turned on for a short time. According to this construction, the lighting time of the light source 3 can be shortened by applying a timer function.
